Its soil is pure silica,so barren it supports only lichens as ground cover.It does,however,sustain a sand-swimming lizard that cannot live where there is moisture or plant matter the soil.两句是连在一起的,出自托福的真题.
第一句主要是 so barren it supports only lichens as ground cover 中,so barren后省略了 that,完整句子应该是so barren that it supports only lichens as ground cover,"这里的土壤是纯的二氧化硅,如此的贫瘠以致于它只能支持苔类作为地表覆盖'第二句你最后多打了the soil两个词,原句是 It does,however,sustain a sand-swimming lizard that cannot live where there is moisture or plant matter.主要4点点:1.强调句,do + verb.表强调,具体参具"强调句_百度百科":2.however 用在句中表(强)转折,这个是很常见的用法,直接翻译成句首"然而"3.lizard that cannot live - 最普通的that 引导的定语从句4.where there is moisture or plant matter 作名词性从句,意思是 "潮湿或有植物的地方",关于句词性从句的具体用法参见"名词性从句_百度百科":/view/414544.htm#7整句意思是 "然而,这种土壤支持着一种在潮湿或有植物地方无法生存的sand-swimming的蜥蜴"

状语从句的概念：
状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。
比较while/as/when：1、as/when引导短暂性动作的动词例句：如：Just as/Just when/When I stopped my car, a man came up to me. 2、当从句的动作发生于主句动作之前，只能用when引导这个从句，不可用as或while。如：When you have finished your work, you may have a rest. 3、从句表示“随时间推移”连词能用as，不用when或while。如：As the day went on, the weather got worse. 比较untill/till： 两个连词意义相同,肯定形式表示的意思是“做某事直至某时”，动词必须是延续性的。否定形式表达的意思是“直至某时才做某事”，动词为延续性或非延续性都可以。正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。肯定句例句：I slept until midnight. 我一直睡到半夜时醒了。 &&&&&&&&&&&&&&&&&&&&&& Wait till I call you. 等着我叫你。注意：在肯定句中可用before代替：Let's get in the wheat before the sunsets. 否定句例句：She didn't arrive until 6o'clock.&&&&&&&&&&&&&&&&&&&&&&&&&I didn't manage to do it until you had explained how. 1、Until可用于句首，而till通常不用于句首。例句：Until you told me, I had heard nothing of what happened. 2、Untilwhen疑问句中，until要放在句首。例句：Until when are you staying? 你呆到什么时候？注意：否定句可用另外两种句式表示。 1）Not until…在句首，主句用倒装。例句：Not until the early years of the19th century did man know what heat is. 2）It is not until…that…
状语从句的用种类：
1、时间状语从句：表示时间的状语从句可由when, as, while, whenever, after, before, till(until), since, once, as soon as(或the moment), by the time, no sooner…than, hardly(scarcely)… when, everytime等引导。 　　e.g. When I came into the office, the teachers were having a meeting. 　　&&&&&& He started as soon as he received the news. 　　&&&&&& Once you see him, you will never forget him. 　　&&&&&& No sooner had I gone to bed than I went to sleep. 　　2、原因状语从句：原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as, nowthat（既然）等，for表示因果关系时（它引导的不是从句）为并列连词，语气不如because强。 　　e.g. He is disappointed because he didn't get the position. 　　&&&&&&As it is raining, I will not go out. 　　&&&&& Now that you mention it, I do remember. 　　3、地点状语从句： 　　引导地点状语从句的连词是where和wherever等。 　　e.g. Sit wherever you like. 　　&&&&&&Make a mark where you have a question. 　　4、目的状语从句： 　　引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。 　　e.g. Speak clearly, so that they may understand you. 　　&&&&&&She has bought the book in order that she could follow the TV lessons. 　　&&&&& He left early in case he should miss the train. 　　5、结果状语从句： 　　结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that（从句谓语一般没有情态动词）,so…that, such…that等引导。 　　e.g. She was ill, so that she didn't attend the meeting. 　　&&&&&&He was so excited that he could not say a word. 　　&&&&& She is such a good teacher that everyone admires her. 　　6、条件状语从句： 　　条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unless, so(as)long as, on condition that, so(as) far as, if only(=if)。注意：条件从句中的if不能用whether替换。 　　e.g. If he is not in the office, he must be out for lunch. 　　&&&&& You may borrow the book so long as you keep it clean. 　　&&&&&&So far as I know（据我所知）, he will be away for three months. 　　&&&&& You can go swimming on condition that(=if) you don't go too far away from the river bank. 　　&&&&&&If he had come a few minutes earlier, he could have seen her. 　7、让步状语从句： 　　让步状语从句可由although, though, as, even if(though), however, whatever, whether…or, no matter who(when, what,…)等引导。注意：as引导的让步状语从句一般是倒装的。 　　e.g. Though he is a child, he knows a lot. 　　&&&&& Child a she is, he knows a lot. 　　&&&&& Whatever(=No matter what) you say, I'll never change my mind. 　　8、方式状语从句： 　　方式状语从句常由as, as if(though), the way, rather than等引导。 　　e.g.You must do the exercise as I show you. 　　&&&&& He acted as if nothing had happened. 　　9、比较状语从句： 　　比较状语从句常用than, so(as)…as, the more…the more等引导。 　　e.g. I have made a lot more mistakes than you have. 　　&&&&& He smokes cigarettes as expensive as he can afford. 　　&&&&& The busier he is, the happier he feels.
使用状语从句时要注意的几个问题：　　
1、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。　　e.g. We'll go outing if it doesn't rain tomorrow. 　　&&&&&& I'll write to you as soon as I get to Shanghai. 　　2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be，就可省略从句中的“主语+be”部分。　　e.g. When(hewas) still a boy of ten, he had to work day and night. 　　&&&&&& If(you are) asked you may come in. 　　&&&&&& If(it is) necessary I'll explain to you again. 　　3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。　　e.g. You are to find it where you left it.（地点状语从句）　　&&&&&& Tell me the address where he lives.（定语从句，句中有先行词）　　&&&&&& I don't know where he came from.（宾语从句）　　&&&&& Where he has gone is not known yet.（主语从句）　　&&&&&& This place is where they once hid.（表语从句）注意：表示“一…就…”的结构 hardly/scarcely…when/before/no sooner…than和as soon as都可以表示“一…就…”的意思。例句：I had hardly/scarcely got home when it began to rain. &&&&&&&&&&& I had no sooner got home than it began to rain. &&&&&&&&&& As soon as I got home, it began to rain. 注意：如果hardly/scarcely或nosooner置于句首，句子必须用倒装结构：例句：Hardly/Scarcely had I got home when it began to rain. &&&&&&&&&&& No sooner had I got home than it began to rain.
限制性定语从句的概念：
限制性定语是指对被修饰名词或代词的必需修饰，是被修饰名词或代词不可缺少的修饰语，如果去掉它句子意思往往会不明确或会发生变化。如：The travellers knowing about the floods took another road. 知道发大水的那些游客改道走了。&&&&&&& The boys wanting to play football were disappointed when it rained. 想踢足球的那些男孩子因为下雨而感到失望。
关系代词引导的定语从句：
关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中所起作用如下： 例：Is he the man who/that wants to see you? 他就是你想见的人吗？（who/that在从句中作主语）&&&&&&&&&&&&&He is the man whom/that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） 2)Whose用来指人或物，(只用作定语,若指物，它还可以同ofwhich互换）例：They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。&& &&&&&&& Please pass me the book whose(of which) coverisgreen. 请递给我那本绿皮的书。 3）which, that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。例如：A prosperity which/that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which/that在句中作宾语） &&&&&&&&&&& The package(which/that) you are carrying is about to come unwrapped.你拿的包快散了。(which/that在句中作宾语）
关系副词引导的定语从句：关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 1）when, where, why 关系副词when, where, why的含义相当于“介词+which”结构，因此常常和“介词+which”结构交替使用。例如：There are occasions when(on which) one must yield.任何人都有不得不屈服的时候。 &&&&&&&&&&& Beijing is the place where(inwhich) I was born. 北京是我的出生地。 &&&&&&&&&&& Is this the reason why(for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗？ 2）that代替关系副词 that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和“介词+which”引导的定语从句，在口语中that常被省略，例如：His father died the year(that/when/in which) he was born. 他父亲在他出生那年逝世了。 &&&&&&&&&&& He is unlikely to find the place(that/where/in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。
限定性定语与非限定性定语的区别：
1、形式不同：限定性定语从句主句和从句之间不用逗号隔开，口语中使用时也不停顿；而非限定性定语从句与主句之间通常有逗号隔开，口语中使用时有停顿。 2、功能不同：&限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意不完整或概念不清；而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意仍然清楚、完整： 如：People who take physical exercise live longer. 进行体育锻炼的人活得长些。(若把从句去掉句子就失去意义) &&&&&&& His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。(若把从句去句子意义仍然完整) 3、翻译不同：在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开： 如：He is the man whose car was stolen. 他就是汽车被窃的那个人。 &&&&&&& I've invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。 4、含义不同： 如：I have a sister who is a doctor. 我有一个医生的姐姐。(姐姐不止一个) &&&&&&& I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。(只有一个姐姐) 5、先行词不同限定性定语从句的先行词只能是名词或代词，而非限定性定语从句的先行词则可以是名词或代词，也可以是短语或句子；另外，当先行词为专有名词或其他具有独一无二性的普通名词时，通常要用非限制性定语从句，而不用限制性定语从句： 如：Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。(which指drive too fast) &&&&&&& He changed his mind, which made me very angry. 他改变了主意，这使我很生气。(which指整个主句) &&&&&&& Mr.Smith, who is our boss, will leave for Japan next week. 我们的老板史密斯先生下周要去日本。(先行词为专有名词，要用非限制性定语从句修饰)&& &&&&&&& Her father, who has a lot of money, wishes her to study abroad. 她父亲很有钱，希望她出国学习。(先行词为表独一无二意义的普通名词，要用非限制性定语从句修饰) 6、关系词不同：关系词that和why可用于限制性定语从句中，通常不用于非限制性定语从句；另外，在限制性定语从句中，关系词有时可以省略，而在非限制性定语从句中关系词一律不省略。
判断关系代词与关系副词方法：
一：用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：This is the mountain village where I stayed last year. &&&&&&&&&&& I'll never forget the days when I worked together with you. 判断改错（错）This is the mountain village where I visited last year. （错）I will never forget the days when I spent in the countryside. （对）This is the mountain village(which) I visited last year. （对）I'll never forget the days(which) I spent in the countryside. 注：习惯上总把表地点或时间的名词与关系副词where, when联系在一起。此两题错在关系词的误用上。二：准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。例1. Is this museum ___ you visited a few days age? &&&&&&& A. where&&&&&&&& B. that &&&&&& &C. on which &&&&&&& D. the one 例2. Is this the museum ____ the exhibition was held.&&&&&&&&& A. where&&&&&&&&&B. that &&&&&&& C.on which &&&&&&& D. the one 答案：例1：D，例2：A 例1变为肯定句：This museum is___ you visited a few days ago. 例2变为肯定句：This is the museum ___ the exhibition was held. 注：在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。而句2中,主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因in the museum词组，可用介词in+which引导地点状语。而此题中，介词on用的不对，所以选A。关系词的选择依据在从句中所做的成分，先行词在从句中作主、定、宾语时，选择关系代词(who,whom,that,which,whose)；先行词在从句中做状语时，应选择关系副词(where地点状语，when时间状语，why原因状语)。
定语从句知识体系：
关系代词that的用法：
1）不用that的情况： a)在引导非限定性定语从句时。 如：（错）The tree, that is four hundred years old, is very famous here. b)介词后不能用： 如：We depend on the land from which we get our food. &&&&&&& We depend on the land that/which we get our food from.2)只能用that作为定语从句的关系代词的情况 a)在there be句型中，只用that，不用which。 b)在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。 c)先行词有the only, the very修饰时，只用that。 d)先行词为序数词、数词、形容词最高级时，只用that。. e)先行词既有人，又有物时。例：All that is needed is a supply of oil. &所需的只是供油问题。&& &&&&&&& Finally, the thief handed everything that he had stolen to the police. 那贼最终把偷的全部东西交给了警察。
主语从句的概念：
如果一个句子在复合句中充当一个主语，那么这个句子就是主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，whichwhatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用。
主语从句用法：
1、主语从句的引导词：主语从句通常由连词that和whether、连接代词或连接副词以及关系代词型what引导： 如：That he is still alive is a wonder. 他还活着，真是奇迹。 &&&&&&& When we arrive doesn't matter. 什么时候到没有关系。 &&&&&&& What we need is money. 我们需要的是钱。 &&&&&&& What I want to know is this. 我想知道的就是这一点。 &&&&&&& Whether they would support us was a problem. 他们是否会支持我们还是一个问题。 2、主语从句与形式主语it：有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。这分三种情况： (1)对于以连词that引导的主语从句，通常用形式主语代主语从句： 如：It's a pity that he didn't come. 很遗憾他没来。 (2)对于以连接代词(副词)引导的主语从句，可以使用形式主语代主语从句，也可直接在句首使用主语从句： 如：Whether they would support us was a problem. 他们是否会支持我们还是一个问题。&&&&&&&&&&It was a problem whether they would support us. 他们是否会支持我们还是一个问题。 (3)对关系代词型what引导的主语从句，通常不用形式主语，总是主语从句放在句首： 如：What we need is money. 我们需要的是钱。 &&&&&&& What I want to know is this. 我想知道的就是这一点。 (4)如果句子是疑问句，则必须用带形式主语it的结构： 如：Is it true that he is the girl's father? 他是那女孩的父亲，是真的吗？ &&&&&&& How is it that you are late again? 你怎么又迟到了？3、连词that的省略问题：引导主语从句的连词that有时可省，有时不能省，其原则是：若that引导的主语从句直接位于句首，则that不能省略；若that引导的主语从句位于句末，而在句首使用了形式主语it，则that则可以省略： 如：That you didn't go to the talk was a pity. 很遗憾你没去听报告。(that不可省) &&&&&&& It was a pity(that) you didn't go to the talk. 很遗憾你没去听报告。(that可省)
主语从句应注意的几个问题：
1、that引导的主语从句既可放在句首，也可放在句尾，但在下列情况下that从句不可提前。（1）在It is said/reported...that结构中： 如：It is reported that a bank was robbed yesterday. （2）在Ithappened/occurred...结构中：Ithappenedthattheteacherwasnotintheofficethatday. （3）含主语从句的复合句是疑问句时：如：Is it ture that you will give up the job? 2、下面这种情况常用it作形式主语。在It doesn't matter+what/whatever…结构中。 如：It doesn't matter what you say. 3、由what引导的主语从句谓语动词单复数问题 what引导的主语从句一般按单数对待，但是，在实际使用中究竟按单数还是按复数对取决于其成分的含义。 如：What we need is more time. &&&&&&& What were left behind were five empty bottles.
同位语从句的概念：
在复合句中充当同位语的名词性从句称为同位语从句。同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一，从句作同位语表示与之同位的名词(短语)的实际内容，它的作用相当于名词，对前面的名词(短语)加以补充说明或进一步解释，相当于一个表语从句，它们之间的关系是同位关系，即主表关系。
同位语从句的用法：
1、同位语从句的引导：词引导同位语从句的词语通常有连词that，whether，连接代词和连接副词等： 如：We heard the news that our team had won. 我们听到消息说我们队赢了。&&& &&&&&&& They were worried over the fact that you were sick. 他们为你生病发愁。&&&&&&&&&I have no idea when he will come back. 我不知道他什么时候回来。 &&&&&&& There is some doubt whether he will come. 他是否会来还不一定。&&&&&&&&&The question whether it is right or wrong depends on the result. 这个是对还是错要看结果。注：whether可引导同位语从句，但if不能引导同位语从句。 2、同位语从句与定语从句的区别： （1）意义的不同：&同位语从句是用于说明所修饰名词的具体内容的，它与被修饰词语通常可以划等号；而定语从句是限制所修饰名词的，它的作用是将所修饰的名词与其他类似的东西区别开来： 如：We are glad at the news that he will come. 听到他要来这个消息我们很高兴。(news的内容就是that he will come，故that引导的是同位语从句) &&&&&&& We are glad at the news that he told us. 听到他告诉我们的这个消息我们很高兴。(that从句是限制thenews的内容的，即我们高兴只是因为他告诉的这个news而不是其他的news，故that从句为定语从句)（2）引导词的不同：&&&&&&&&& what, how, if, whatever等可引导名词性从句，但不引导定语从句。 （3）引导词的功能上的不同：&&&&&&&&& that引导同位语从句时，它不充当句子成分，而引导定语从句时，它作为关系代词，要么充当定语从句的主语，要么充当定语从句的宾语。如上例that he told us中的that就充当told的宾语。 （4）被修饰词语的区别：&&&&&&&&& 同位语从句所修饰的名词比较有限，通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等，而定语从句所修饰的名词则非常广泛。另外，when和where引导定语从句时，通常只修饰表示时间和地点的名词，而它们引导同位语从句时却不一定；又如why引导定语从句，它通常只修饰名词thereason，而它引导同位语从句时则不一定： 如：I have no idea when they will come. 我不知道他们什么时候来。(同位语从句) &&&&&&& I'll never forget the days when I lived there. 我永远不会忘记我住在那儿的日子。(定语从句) &&&&&&& We don't understand the problem why this is the best choice. 我们不明白这个问题，为什么这是最好的选择。(同位语从句)&&&&&& &There a son why he didn't come to the meeting is that he is ill. 他未能来开会，原因是他生病了。(定语从句)
同位语从句用法解析：
一、理解同位语从句的含义，把握同位语从句的实质：　　在主从复合句中作同位语的从句称为同位语从句。同位语从句一般用that, whether, what, which, who, when, where, why, how等词引导，常放在fact, news, idea, truth, hope, problem, information, wish, promise, answer, evidence, report, explanation, suggestion, conclusion, word, possibility等抽象名词后面，说明该名词的具体内容。换言之，同位语从句和所修饰的名词在内容上为同一关系，对其内容作进一步说明。例：The news that they had won the game soon spread over the whole school. 他们比赛获胜的消息很快传遍了整个学校。析：they had won the game说明the news的全部内容，因此该句为同位语从句。二、正确运用同位语从句的引导词，准确把握同位语从句：1、如同位语从句意义完整，应用that引导同位语从句。（即that不充当任何成分，只起连接作用，不可省略）　例：The general gave the order that the soldiers should cross the river at once. 将军下达了战士们立即过河的命令。　析：the soldiers should cross the river at once是the order的全部内容，且意义完整，因此应用that引导同位语从句。 2、如同位语从句意义不完整，需增加"是否"的含义，应用whether引导同位语从句。（if不能引导同位语从句）例：We'll discuss the problem whether the sports meeting will be held on time. 我们将讨论运动会是否会如期举行的问题。析：the sports meeting will be held on time 意义不完整，应加“是否”的含义才能表达the problem的全部内容，因此应用whether引导同位语从句。 3、如同位语从句意义不完整，需增加"什么时候"、"什么地点"、"什么方式"等含义，应用when, where, how等词引导同位语从句。　例1：I have no idea when he will be back. 　析：he will be back 意义不完整，应加"什么时候"的含义才能表达idea的全部内容，因此应用when引导同位语从句。　例2：I have no impression how he went home, perhaps by bike. 析：he went home 意义不完整，应加"如何"的含义才能表达impression的全部内容，因此应用how引导同位语从句。 4、当主句的谓语较短，而同位语从句较长时，同位语从句常后置。如：The thought came to him that may be the enemy had fled the city.

1、 Have you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you think caused this change in colour? It is soil that has been washed into the river from the riverbank or from t}le nearby fields．Components of SoftSoil is made up of a number of layers（层），each having its own distinctive colour and texture．The upper layer is known as the litter．It acts like a blanket．limiting temperature changes and reducing water loss．The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus（腐殖质），which is black and gives the topsoil its dark colour．This layer is usually rich in nutrients，oxygen，and water．Below the topsoil is the subsoil，a layer that contains more stones mixed with only small amounts of organic matter．This layer is lighter in colour because of the lack of humus．Beneath the soil lies a layer of bedrock．Soil forms from the bottom up．Over time bedrock is attacked by rain, wind，frost, and snow．It is gradually broken down into smaller particles in a process called weathering．Plants begin to grow，and rotten materials enrich the topsoil．Most of the soil in Eastern Canada．for example．Was formed from weathered rock that was exposed when the ice disappeared l2.000 years ag0．Water Beneath the SoilSurface water collects and flows above the ground in lakes．ponds．and rivers．Once in the soil or rock，it is called groundwater．Gravity pulls groundwater through the soil in a process called percolation（渗透）．Eventually the water reaches a layer called the water table．Under this is bedrock through which water cannot percolate．As water percolates downward，it dissolves organic matter and minerals from the soil and carries them to deeper layers．This causes a serious problem because plants require these nutrients for growth.Soil pHSoil can be acidic．neutral．or basic．The pH of the soil is determined by the nature of the rockfrom which it was formed．and by the nature of t}le plants that grow and rot in it．The acidity of rain and snow can lower the pH of the groundwater that enters the soil．By burning fossil fuels such as coal，oil and gasoline，humans have been contributing to higher levels of acidity in many soils．When fossil fuels are burned．gases are released into the air and then fall back to earth as acid rain．Acid soil increases出e problem of carrying nutrients to lower soil levels．As nutrients are removed，soil is less fertile．Plants grow more slowly in acidic soil，and also become easily attacked by diseases．1、The layer of soil that provides necessary nutrients for plant growth is called．A．1itterB．topsoilC．humusD．subsoil2、According to the text．which of the following is NOT true?A．Soil forms from weathered rock on the earth surface．B．The deeper layer of soil is darker in colour than t}le surface soil．C．Air pollution is partially responsible for acid soil．D．Groundwater tends to carry away nutrients for plant growth．3、We can infer from the passage that the water table lies ．A．between the topsoil layer and the subsoil layerB．in the subsoil layer above bedrockC．between the subsoil layer and bedrockD．in the bedrock layer beneath the subsoil4、The underlined word “dissolve” is used to express the idea that organic matter and minerals from soil are ．A．rushed away into the riverB．cleaned and purified by waterC．destroyed and carried away by waterD．mixed with water and become part of it
2、 When Jackie Robinson walked onto Ebbets Field in Brooklyn, New York, on April 15, 1947, he changed baseball forever. As the first African American to play in the Major League in modern times, many believe he changed the country forever.Robinson was born in 1919. He lived in a time when rules controlled what African Americans could do. He was a top athlete, playing football, basketball and baseball. But playing for a major League team was off limits to Robinson because of his race. Branch Rickey, president and manager of the Brooklyn Dodgers, signed (和……签约) Robinson in 1947. He believed that Robinson not only had the skills, but the courage to face the challenge of becoming modern baseball’s first black player.It wasn’t easy. Robinson sometimes faced boos (嘘声) from fans. But he became a star, anyway. In 1962, he became the first African-American player chosen to enter the Baseball Hall of Fame. In 2005, he was awarded a Congressional Gold Medal, the highest award Congress can give to an American.By breaking baseball’s color barrier (肤色障碍), Robinson opened the door for many to follow his footsteps, not only in baseball, but in other areas of life as well. After he stopped playing the game, Robinson worked as a manager for a coffee company. He wrote a newspaper column (专栏). He also

3、 Pingyao, in the center of Shanxi Province, is a famous historic cultural city of China and a world cultural heritage site (世界文化遗址). It’s 90 kilometers south of Taiyuan on the Fen River.People lived in Pingyao during the New Stone Age. Its long period as a country government seat has left Pingyao with lots of historic buildings and sites, with a 2,700-year history. Ninety-nine of them are under government protection, including Zhengguo Temple, Shuanglin Temple and Pingyao Ancient City.During the Ming and Qing Dynasties, businessmen organized commercial (商业的) groups that did business nationwide. Shanxi Province had some of the most important ones and Pingyao was their center. In 1823, a store, known as Rishengchang(Sunrise Prosperity), traded in bank checks rather than in silver or gold coins. It was the beginning of modern Chinese banking. Branch banks were soon set up in major cities in China and other parts of Asia, leading to great development in Pingyao. Its Lacquer ware (漆器) became well known.In Pingyao Ancient City are many traditional houses and commercial buildings, 3,797 of which are protected and more than 400 of which are in good condition. Not only do the houses in Pingyao show Shanxi’s history and culture, but this large number is valuable for studying its history, customs, and ancient buildings and art.

8、 There is an old saying in English： "Laughter is the best medicine". Until recently, few people took the saying very seriously. Now, however, doctors have begun to investigate laughter and the effects it has on the human body. They have found evidence that laughter really can improve people's health.Tests were carried out to study the effects of laughter on the body. People watched funny films, while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing； it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.Other tests have shown that laughter appears to be capable of reducing the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which tolerated the pain for the longest time was 'the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce endorphins （内啡肽） in the brain. These are natural chemicals which diminish both stress and pain.There is also some evidence to suggest that laughter helps the body's immune(免疫的)system, that is, the system which fights infection. In an experiment, one group of students watched a funny video while another group served as the control group - in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells, that is, the cells which fight infection.As a result of these discoveries, some doctors and psychiatrists （精神病学家） in the United States now hold laughter clinics, in which they try to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.1、 We learn from the first paragraph that laughter____________________. A．is good for one's healthB．is related to some illnessC．has been investigated long sinceD．has no effect on the body2、Doctors have found that laughter_______________________. A．keeps down blood pressure.B．has similar effects to physical exerciseC．decreases the heart rateD．increases stress3、Which of the following statements is NOT true of laughter, according to the passage?A．It reduces pain. B．It exercises the body. C．It improves the body's immune system. D．It can cure cancer.4、The writer's attitude towards laughter is__________. A．criticalB．doubtfulC．positiveD．negative
9、 Reduce, reuse, and recycle. This familiar environmentalist slogan tells us how to reduce the amount of rubbish that ends up in landfills and waterways. The concept is being used to deal with one possibly dangerous form of waste — electronic junk (电子垃圾), such as old computers, cell phones, and televisions. But this process for managing e-waste may be used in an unscrupulous way more often than not used, a recent report suggests.“A lot of these materials are being sent to developing nations under the excuse of reuse — to bridge the digital divide,” said Richard Gutierrez, a policy researcher.One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, e-waste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment.Businessmen also pay workers a little money to get back materials such as gold and copper. This low-tech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.”China, for example, has become a dumping place for large amounts of e-waste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial is finally beginning to take the lead.1、 The passage mainly tells us that _______.A．developing countries are facing serious environmental problemsB．e-waste is sent to developing countries under the excuse of reuseC．developing countries are making full use of e-wasteD．e-waste is a growing problem in developed countries2、What does the third paragraph mainly discuss?A．A lot of e-waste is dumped in developing countries.B．Poor people break up e-waste to collect some valuable materials. C．The problem of e-waste is growing in developing countries.D．Old computers and TVs still work before they are sent abroad.3、The underlined word “unscrupulous” in Paragraph 1 probably means “________”.A．immoralB．wrongC．proudD．unsafe4、From what Gutierrez said we can learn that ________.A．developing countries should be responsible for this problemB．exporting countries should be mainly responsible for this problemC．neither rich nor poor countries should be blamed for this problemD．poor countries should be blamed for this problem
10、 Preparing for the Next Job MarketThe latest spike in the unemployment rate is being felt across the board ?in 98 percent of metropolitan areas, in high-wage and low-wage jobs, among young and old, women and men, but especially men．This landscape means that young Americans who are trying to plan their futures right now have some hard choices．Do they go to college and take on debt without hope of getting a job? And what about high school students? Do they have any chance of securing a job without a college degree? Perhaps the education system needs to react to this rapidly moving economic crisis．In our current economic collapse, the connection between education and employment could not be more different than it was during the Depression．Education must now hold center stage, not because of an enemy abroad but because of the global economy．The jobs of the future will demand levels of education, particularly skills in mathematics, technology and science, which exceed those now taught in high school．A healthy society should strive for full employment．In our times, that goal cannot be realized, or even approximated by creating jobs for the unskilled．The long-term prospect for economic recovery depends on the extent to which we improve our educational system．And this is where America is now at its weakest．##Our high schools produce graduates who do not write well enough, have limited reasoning skills and are unable to use the tools of mathematics．Their command of science is far inferior to that of their counterparts in other nations．And all too many young people drop out．We may still have the best university system, but it benefits only a minority．We will need more engineers, scientists and service providers, particularly in the health professions, with a quality of education that cannot be obtained in the current system．Radical change, not reform, is called for．What should be done? First, high school should be cut short and end when students are 16．Second, a new generation of two-year college programs tied to a wide range of specific skills that the economy needs should be created．Third, access to four-year colleges should be expanded, giving more Americans the chance to acquire the deep learning that makes breakthroughs in technology possible．Fourth, we need to recruit more public school teachers and train them better, particularly in physics, chemistry, biology and mathematics, so that our children can be prepared to compete．1、Nowadays, students graduating from high school____．A．write well enoughB．have limitless reasoning skillsC．can't use the tools of mathematicsD．command science as much as their counterparts in other nations2、What should we do to improve the quality of education?A．Students shouldn't study in high school until 16．B．We should create a new generation of two-year college programs tied to a wide range of specific skills the economy needs．C．We should limit access to four-year colleges．D．We ought to recruit more private school teachers and train them better．3、What does the word "collapse" in the third paragraph mean?A．successB．failureC．developmentD．booming4、Which of the following is NOT true according to the passage?A．Young Americans planning their futures have difficult choices．B．Education must hold center stage due to the global economy．C．The best university system benefits a majority．D．A health society should struggle for full employment．
11、 The food we eat seems to have great effects on our health. Although science has made great steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to diet as well. Different cultures are subject to certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates(硝酸盐) and nitrites(亚硝酸盐), commonly used to keep color in meats, and other food additives, caused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels(标签) of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to cows and chick and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are given to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although the FDA has tried repeatedly to control these, the practices continue.1、How has science done a bad service to mankind?A．Diseases caused by food have been done away with.B．It has caused a lack of information about the value of food.C．Some harmful materials have been added to our food.D．Scientists have made food more expensive to eat.2、What are nitrates used for?A．They help process packaged food.B．They keep the color in meats.C．They cure diseases of cows and chickens. D．They cause the animals to become fatter.3、Which of the following statements is NOT true?A．You can find out harmful additives on the packaging labels of food.B．Drugs given to animals are not all for medical reasons.C．Researchers knew about the harm of food additives about 60 years ago.D．Food may cause forty percent of cancer in the world.4、According to the passage, the FDA might be _________.A．an organization which controls the safety of food B．a producer which makes additivesC．a factory which processes foodD．a hospital which cures cancer
12、 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。During the first half of the nineteenth century in the United States, Christmas was a very different kind of holiday than it is today. There was no set of way of celebrating the day,which was not yet an official holiday.
71 Some observed Christmas as an important Christian religious day honoring the birth of Jesus.Others celebrated the day with parties,music,drinking and eating.
.Calvinist Christians banned the celebration of Christmas.But groups such as Episcopaliansand Moravians honored the day with religious services and seasonal decorations.By mid-century,Christian groups began to ignore their religious diffrences over the meaning of Christmas and honored the day in special ways.Christmas became an important time for families to celebrate at home. More and more Christians Americans also began to follow the European traditions of Christmas trees and giving gifts.Christians believed that the tree represented Jesus and was also a sign of new beginnings. German immigrants brought their tradion of putting lights,sweets and toys on the branches of evergreen trees placed in their homes.This tradition of setting up a Christmas tree soon spread to many American homes.
74 As these traditions increased in popularity,the modern trade and business linked to Christmas also grew.As Christmas became more popular,some states declared the day a state holiday.Louisiana was the first state to make the move in eighteen thirty-seven.
.It was not until eighteen seventy that President Ulysses Grant made Christmas a federal holiday.A．So did the practice of giving people presents.B．By eighteen sixty,fourteen other states had followed.C．And,some communities did not celebrate the day at all.D．Americans seldom gave each other presents on Christmas Day.E.

14、 There was such a long queue for fried chicken at KFC that we_____ gave up. A．eventuallyB．unfortunatelyC．generouslyD．purposely
15、 In Europe people hold the fork in the left hand and the knife in the right throughout the meal, a system that is generally agreed to be more efficient than the American zigzag（曲折的）method. Americans hold both the fork and the knife in their right hands throughout the meal, so they continually change their forks to the left hand when they have to cut their meat. It seems to be funny for the Europeans to see Americans busy changing their dinner sets, making a lot of noises. A few explanations for this American style are as follows:(1)Americans are practical and efficient. Since most of us are right-handed, it is reasonable to keep our working tools at all times in the right hand that can use them most efficiently.?(2)Americans, the master of the New World are rebels（叛逆者）.They use the zigzag method to break the rules in the Old World and in this way they are thumbing their nose at Mother England. Americans are a restless kind. They do not like to sit in one spot for very long when dining.(3)Forced to do so, they respond by “playing” with the silver.?Whatever the reason for the practice, it is now certainly as American as apple pie. Europeans recognize this and are quick to attack it as evidence of American innocence（无知）of form. Arguments against the zigzag method rest not only on grounds of efficiency but also on those of tradition. In Old World dining, the knife is held in the right hand continually because it can serve as an instant defense against the uninvited intruders（入侵者）.However, such alertness（警觉） is out of place in the New World, as every American believes that this is the home of the brave. Americans juggle their silverware, perhaps, to show that they are not afraid and that one of them holding a fork is worth any number of them holding blades（刀）.?1、Americans use _______ to hold their fork to pick up the salad.?A．the right handB．the left hand?C．both handsD．either of the two hands?2、As the masters of the New World, Americans use a different cutting method from that in the Old World to _______.?A．show their independence of Mother England?B．show their disrespect to Mother England?C．add a new tradition to those in Mother England?D．show off their creativeness to Mother England?3、In the sentence, the word “juggle” probably means _______.?A．holdB．play withC．pick upD．lay down??4、Which of the following statements is NOT true? ?A．European people hold the fork in the left hand and the knife in the right hand.B．The zigzag eating method is related to American characteristics.?C．The zigzag eating method has become an American feature.?D．European people will use the American method because of its efficiency.
16、 In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They found out that any major change can be stressful. Negative events like “serious illness of a family member” were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not show how you deal with stress—it only shows how much you have to deal with. And we now know that the way you deal with these events has a great effect on your chances of staying healthy.By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women's magazines ran headlines like “Stress causes illnesses”.If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. even if stressful events are dangerous, many—like the death of a loved one—are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription(处方) for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move.?The idea that all stress makes you sick also takes no notice of what we know about people. It is supposed that we're all weak and passive in the face of difficulty. But many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and mental damage.1、The result of Holmes-Rahe’s medical research tells us _______.?A．what should be done to avoid stress?B．the way of dealing with major events may cause stress?C．what kind of event would cause stress?D．how to deal with sudden changes in life?2、The studies on stress in the early 1970's led to_______.?A．great fear about the mental problems it could cause?B．widespread worry over its harmful effects?C．a deep research into illnesses connected with stress?D．popular avoidance of stressful jobs?3、According to the passage people who have experienced ups and downs may become___.A．discouraged when faced with difficultyB．physically and mentally weak?C．more experienced in the face of difficultyD．uninterested in what happens to them4、What’s the purpose of writing the text? ?A．To tell people the discoveries about stress.?B．To tell people how to keep healthy.?C．To help people avoid stressful events.?D．To help people view stress properly.
