【摘要】鉴于大家对十分关注，小编在此为大家搜集整理了此文&英语语法大全&，供大家参考!本文题目：高中英语语法大全词法第1章 主谓一致一.概念:主谓一致是指：1) 语法形式上要一致，即单复数形式与谓语要一致。2) 意义上要一致，即主语意义上的单复数要与谓语的单复数形式一致。3) 就近原则，即谓语动词的单复形式取决于最靠近它的，一般来说，不可数名词用动词单数，可数名词复数用动词复数。例如：There is much water in the thermos.但当不可数名词前有表示数量的复数名词时，谓语动词用复数形式。例如：Ten thousand tons of coal were produced last year.二.相关知识点精讲1.并列结构作主语时谓语用复数，例如：Reading and writing are very important. 读写很重要。注意：当主语由and连结时，如果它表示一个单一的概念，即指同一人或同一物时，谓语动词用单数，and 此时连接的两个词前只有一个冠词。例如：The iron and steel industry is very important to our life. 钢铁工业对我们的有重要意义。典型例题The League secretary and monitor ___ asked to make a speech at the meeting.A. is　　B. was　 C. are　 D. were答案B. 注： 先从时态上考虑。这是过去发生的事情应用过去时，先排除A.，C。本题易误选D，因为The League secretary and monitor 好象是两个人，但仔细辨别，monitor 前没有the，在英语中，当一人兼数职时只在第一个职务前加定冠词。后面的职务用and 相连。这样本题主语为一个人，所以应选B。2. 主谓一致中的靠近原则1)当there be 句型的主语是一系列事物时，谓语应与最邻近的主语保持一致。例如：There is a pen, a knife and several books on the desk. 桌上有一支笔、一把小刀和几本书。There are twenty boy-students and twenty-three girl-students in the class.班上有二十个男孩，二十三个女孩。2)当either... or... 与neither... nor，连接两个主语时，谓语动词与最邻近的主语保持一致。如果是由here, there引导，而主语又不止一个时，谓语通常也和最邻近的主语一致。例如：Either you or she is to go. 不是你去，就是她去。Here is a pen, a few envelops and some paper for you. 给你笔、信封和纸。3.谓语动词与前面的主语一致当主语有with, together with, like, except, but, no less than, as well as 等词组成的短语时，谓语动词与前面的主语部分一致。例如：The teacher together with some students is visiting the factory. 教师和一些学生在参观工厂。He as well as I wants to go boating.他和我想去划船。4. 谓语需用单数的情况1)代词each以及由every, some, no, any等构成的复合代词作主语时，或主语中含有each, every时, 谓语需用单数。例如：Each of us has a tape-recorder. 我们每人都有录音机。There is something wrong with my watch. 我的表坏了。2)当主语是一本书或一条格言时，谓语动词常用单数。例如：The Arabian Night is a book known to lovers of English. 《天方夜谭》是英语爱好者熟悉的一本书。3)表示金钱，时间，价格或度量衡的复合名词作主语时，通常把这些名词看作一个整体，谓语一般用单数。例如：Three weeks was allowed for making the necessary preparations. 用三个星期来做准备。Ten yuan is enough. 十元够了。5.指代意义决定谓语的单复数1)代词what, which, who, none, some, any, more, most, all等词的单复数由其指代的词的单复数决定。例如：All is right.　一切顺利。All are present.　人都到齐了。2)集体名词作主语时，谓语的数要根据主语的意思来决定。如family, audience, crew, crowd, class, company, committee等词后，谓语动词用复数形式时强调这个集体中的各个成员，用单数时强调该集体的整体。例如：His family isn't very large. 他家成员不多。His family are music lovers.　他家个个都是音乐爱好者。但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。例如：Are there any police around? 附近有警察吗?3)有些名词，如variety, number, population, proportion, majority 等有时看作单数，有时看作复数。例如：A number of +名词复数+复数动词。The number of +名词复数+单数动词。A number of books have lent out.The majority of the students like English.6.与后接名词或代词保持一致的情况1)用half of, most of, none of, heaps of, lots of, plenty of 等引起主语时，谓语动词通常与of后面的名词/代词保持一致。例如：Most of his money is spent on books. 他大部分的钱化在书上了。Most of the students are taking an active part in sports. 大部分学生积极参与体育运动。2)用a portion of, a series of, a pile of, a panel of 等引起主语时，谓语动词通常用单数。例如： A series of accidents has been reported. 媒体报道了一连串的事故。A pile of lots was set beside the hearth. 炉边有一堆木柴。3)如 many a 或 more than one 所修饰的短语作主语时，谓语动词多用单数形式。但由more than... of 作主语时，动词应与其后的名词或代词保持一致。例如：Many a person has read the novel.　许多人读过这本书。More than 60 percent of the students are from the city.百分之六十多的学生来自这个城市。三.巩固练习( ) 1.

(含义：达比太太已不再住在肯塔基州。)Mrs. Darby has lived in Kentucky for seven years. (含义：现在还住在肯塔基州，有可能指刚离去)注意： 用过去时表示现在，表示委婉语气。1)动词want, hope, wonder, think, intend 等。例如：Did you want anything else? 您还要些什么吗?I wondered if you could help me. 能不能帮我一下。2)情态动词 could, would。例如：Could you lend me your bike? 你的自行车，能借用一些吗?3.一般将来时1)　shall用于第一人称，常被will 所代替。will 在陈述句中用于各人称，在征求意见时常用于第二人称。例如：Which paragraph shall I read first? 我先读哪一段呢?Will you be at home at seven this evening? 今晚七点回家好吗?2)　be going to +不定式，表示将来。a. 主语的意图，即将做某事。例如：What are you going to do tomorrow? 明天打算作什么呢?b. 计划，安排要发生的事。例如：The play is going to be produced next month。这出戏下月开播。c. 有迹象要发生的事。例如：Look at the dark clouds, there is going to be a storm. 看那乌云，快要下雨了。3)　be +不定式表将来，按计划或正式安排将发生的事。例如：We are to discuss the report next Saturday.我们下星期六讨论这份报告。4)　 be about to +不定式，意为马上做某事。例如：He is about to leave for Beijing. 他马上要去北京。注意：be about to do 不能与tomorrow, next week 等表示明确将来时的时间状语连用。4. 一般现在时表将来1)下列动词come, go, arrive, leave, start, begin, return的一般现在时可以表示将来，主要用来表示在时间上已确定或安排好的事情。例如：The train leaves at six tomorrow morning. 火车明天上午六点开。When does the bus star? It stars in ten minutes. 汽车什么时候开?十分钟后。2)以here, there等开始的倒装句，表示动作正在进行。例如：Here comes the bus. = The bus is coming. 车来了。There goes the bell. = The bell is ringing. 铃响了。3)在时间或条件句中。例如：When Bill comes (不是will come), ask him to wait for me. 比尔来后，让他等我。I'll write to you as soon as I arrive there. 我到了那里，就写信给你。4)在动词hope, take care that, make sure that等的宾语从句中。例如：I hope they have a nice time next week. 我希望他们下星期玩得开心。Make sure that the windows are closed before you leave the room. 离开房间前，务必把窗户关了。5. 用现在进行时表示将来下列动词come, go, arrive, leave, start, begin, return等现在进行时可以表示将来。例如：I'm leaving tomorrow. 明天我要走了。Are you staying here till next week? 你会在这儿呆到下周吗?6. 现在完成时现在完成时用来表示之前已发生或完成的动作或状态，其结果的影响现在还存在;也可表示持续到现在的动作或状态。其构成：have (has) +过去分词。7. 比较一般过去时与现在完成时1)一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作;现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。2)一般过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。一般过去时的时间状语：yesterday, last week，...ago, in1980, in October, just now等，皆为具体的时间状语。现在完成时的时间状语：for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等，皆不确定的时间状语。共同的时间状语：this morning, tonight, this April, now, already, recently, lately 等。3)现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, work, study, know.。一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。例如：I saw this film yesterday. (强调看的动作发生过了)I have seen this film. (强调对现在的影响，电影的内容已经知道了)Why did you get up so early? (强调起床的动作已发生过了)Who hasn't handed in his paper? (强调有卷子未交，疑为不公平竞争)He has been in the League for three years. (在团内的状态可延续)He has been a League member for three years. (是团员的状态可持续)句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时，不能使用现在完成时，要用过去时。(错)Tom has written a letter to his parents last night.(对)Tom wrote a letter to his parents last night.8. 用于现在完成时的句型1)It is the first / second time.... that...结构中的从句部分，用现在完成时。例如：It is the first time that I have visited the city. 这是我第一次访问这城市。This is the first time (that) I've heard him sing.　这是我第一次听他唱歌。注意：It was the third time that the boy had been late.2)This is +形容词最高级+that...结构，that 从句要用现在完成时。例如：This is the best film that I've (ever) seen. 这是我看过的最好的电影。9.过去完成时1) 概念：表示过去的过去--------------------------& 其构成是had +过去分词构成。那时以前　 那时　 现在2) 用法a. 在told, said, knew, heard, thought等动词后的宾语从句。例如：She said (that)she had never been to Paris. 她告诉我她曾去过巴黎。b. 状语从句在过去不同时间发生的两个动作中，发生在先，用过去完成时;发生在后，用一般过去时。例如：When the police arrived, the thieves had run away. 警察到达时，小偷们早就跑了。c. 表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示&原本...，未能...&。例如：We had hoped that you would come, but you didn't. 那时我们希望你能来，但是你没有来。3)　过去完成时的时间状语before, by, until , when, after, once, as soon as。例如：He said that he had learned some English before. 他说过他以前学过一些英语。By the time he was twelve, Edison had began to make a living by himself. 到了十二岁那年，爱迪生开始自己谋生。Tom was disappointed that most of the guests had left when he arrived at the party.汤姆失望了，因为他到达晚会时，大部分客人已经走了。10. 用一般过去时代替过去完成时1)　两个动作如按顺序发生，又不强调先后，或用then，and，but 等连词时，多用一般过去时。例如：When she saw the mouse，she screamed. 她看到老鼠，就叫了起来。My aunt gave me a hat and I lost it. 姑妈给了我一顶帽子，我把它丢了。2 ) 两个动作相继发生，可用一般过去时;如第一个动作需要若干时间完成，用过去完成时。例如：When I heard the news, I was very excited.3)　叙述历史事实，可不用过去完成时，而只用一般过去时。例如：Our teacher told us that Columbus discovered America in 1492.11.将来完成时1) 构成will have done2) 概念a. 状态完成：表示某事继续到将来某一时为止一直有的状态。例如：They will have been married for 20 years by then. 到那时他们结婚将有二十年了。b. 动作完成：表示将来某一时或另一个将来的动作之前，已经完成的动作或获得的经验。例如：You will have reached Shanghai by this time tomorrow. 明天此时，你已经到达上海了12现在进行时现在进行时的基本用法：a. 表示现在(指说话人说话时)正在发生的事情。例如：We are waiting for you. 我们正在等你。b. 习惯进行：表示长期的或重复性的动作，说话时动作未必正在进行。例如：Mr. Green is writing another novel.　他在写另一部小说。(说话时并未在写，只处于写作的状态。)c. 表示渐变，这样的动词有：get, grow, become, turn, run, go, begin等。例如：The leaves are turning red. 叶子在变红。It's getting warmer and warmer. 天越来越热了。d. 与always, constantly, forever 等词连用，表示反复发生的动作或持续存在的状态，往往带有说话人的主观色彩。例如：You are always changing your mind. 你老是改变主意。13. 过去进行时1)概念：表示过去某时正在进行的状态或动作。2)过去进行时的主要用法是描述一件事发生的背景;一个长动作延续的时候，另一个短动作发生。3) 常用的时间状语有this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while等。例如：My brother fell while he was riding his bicycle and hurt himself.　 我兄弟骑车时摔了下来，受了伤。It was raining when they left the station. 他们离开车站时，正下着雨。When I got to the top of the mountain, the sun was shining.　我到达山顶时，阳光灿烂。14. 将来进行时1) 概念：表示将来某时进行的状态或动作，或按预测将来会发生的事情。例如：She'll be coming soon. 她会很快来的。I'll be meeting him sometime in the future. 将来我一定去见他。注意：将来进行时不用于表示&意志&，不能说 I'll be having a talk with her.2)常用的时间状语有soon, tomorrow, this evening，on Sunday, by this time，tomorrow, in two days, tomorrow evening等。例如：By this time tomorrow, I'll be lying on the beach. 明天此时，我正躺在海滩上呢。15. 一般现在时代替一般将来时When, while, before, after, till, once, as soon as, so long as, by the time, if, in case (that), unless, even if, whether, the moment, the minute, the day, the year, immediately等引导的时间状语从句，条件句中，用一般现在时代替将来时。例如：He is going to visit her aunt the day he arrives in Beijing. 他一到北京，就去看他姨妈。16. 一般现在时代替一般过去时1 ) &书上说&，&报纸上说&等。例如：The newspaper says that it's going to be cold tomorrow. 报纸上说明天会很冷的。2) 叙述往事，使其生动。例如：Napoleon's army now advances and the great battle begins.拿破仑的军队正在向前挺进，大战开始了17. 一般现在时代替现在完成时1) 有些动词用一般现在时代替完成时，如hear, tell, learn, write , understand, forget, know, find , say, remember等。例如：I hear (= have heard) he will go to London. 我听说了他将去伦敦。I forget (=have forgotten) how old he is. 我忘了他多大了。2) 用句型 & It is ... since...&代替&It has been ... since ...&。例如：It is (= has been) five years since we last met. 从我们上次见面以来，五年过去了。18. 一般现在时代替现在进行时。在Here comes.../There goes...等句型里，用一般现在时代替现在进行时。例如：There goes the bell. 铃响了。19. 现在进行时代替将来时1) 表示即将发生的或预定中计划好的活动。例如：Are you staying with us this weekend? 和我们一起度周末好吗?We are leaving soon.　 我们马上就走。2) 渐变动词，如get, run, grow, become, begin以及瞬间动词die等。例如：He is dying. 他要死了。20.时态一致1) 如果从句所叙述的为真理或相对不变的事实，则用现在时。例如：At that time, people did not know that the earth moves. 那时，人们不知道地球是动的。He told me last week that he is eighteen. 上星期他告诉我他十八岁了。2) 宾语从句中的，助动词ought, need, must, dare 的时态是不变的。例如：He thought that I need not tell you the truth. 他认为我不必告诉你真相。三.巩固练习:1、I' ll give the book to him as soon as he ________ back.2、Has the baby ________ crying yet?

It's for sb.和 It's of sb.这样的句子中，由于表语形容词性质的不同，导致了不定式逻辑主语标志用for或of的区别。1)for sb. 句型中的形容词一般为表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult, interesting, impossible等：例如：It's very hard for him to study two languages. 对他来说学两门外语是很难的。2)of sb句型中的形容词一般为表示性格，品德，心智能力，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。例如：It's very nice of you to help me. 你来帮助我，你真是太好了。用for还是用of 的另一种辨别方法：用介词for或of后面的逻辑主语作句子的主语，用介词前边的形容词作表语，造个句子。如果通顺用of，不通则用for。例如：You are nice.　(通顺，所以应用of)。He is hard.　 (非所表达的意思，不通，因此用for。)4. 不定式作表语不定式可放在be动词后面，形成表语。例如：My work is to clean the room every day. 我的工作是每天清扫房间。His dream is to be a doctor. 他的梦想是成为一名医生。5. 不定式作定语不定式做定语通常要放在被修饰的词后，往往表示未发生的动作。例如：I have a lot of work to do.　我有许多事要做。There was nothing to bring home that morning. 那天早上(他回家时)两手空空。6. 不定式作状语1)目的状语常用结构为to do , only to do(仅仅为了), in order to do,　so as to do,　so(such)... as to...(如此...以便...)。例如：He ran so fast as to catch the first bus.　他飞快地跑以便赶上第一班车。I come here only to say good-bye to you.　我来仅仅是向你告别。2)作结果状语，可以表示没有预料到的或事与愿违的结果，不定式要放在句子后面。I awoke to find my truck gone. 我醒来发现箱子不见了。He searched the room only to find nothing. 他搜索了房间，没发现什么。3) 表原因I'm glad to see you. 见到你很高兴。She wept to see the sight. 她一看到这情形就哭了。4)表示理由和条件He must be a fool to say so.You will do well to speak more carefully.7.用作介词的toto 可以用作介词，也可用作不定式的标示。下面的to 都用作介词：admit toobject tobe accustomed tobe used tostick toturn to开始look forward tobe devoted topay attention tocontribute toapologize todevote oneself to8. 省去to 的动词不定式1) 情态动词 ( 除ought 外) 后。2) 使役动词 let, have, make后，感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后。注意：被动语态中不能省去to。例如：I saw him dance. 我看见他跳舞。=He was seen to dance.The boss made them work the whole night. 老板让他们整夜干活。=They were made to work the whole night.3) would rather，had better句型后4) Why... / why no...句型后5) help 后可带to，也可不带to, help sb (to) do sth：6) but和except后。but前是实义动词do时，后面出现的不定式不带to。比较：He wants to do nothing but go out. 他只想出去玩。He wants to believe anything but to take the medicine. 除了吃这药，他什么都信。7) 由and, or和than连接的两个不定式，第二个to 可以省去：8) 通常在discover, imagine, suppose, think等词后作宾补时，可以省去to be。例如：He is supposed (to be) nice.　他应该是个好人。9.动词不定式的否定式在不定式标志to前加上not。例如：Tell him not to shut the window。让他别关窗。She pretended not to see me when I passed by. 我走过的时候，她假装没看见。10.不定式的特殊句型too...to...1)too...to　 太...以至于...。例如：He is too excited to speak. 他太激动了，说不出话来。---- Can I help you ? 需要我帮忙吗?---- Well, I'm afraid the box is too heavy for you to carry it, but thank you all the same.不用了。这箱子太重，恐怕你搬不动。谢谢。2) 如在too前有否定词，则整个句子用否定词表达肯定，too 后那个词表达一种委婉含义，意 为&不太&。例如：It's never too late to mend.　 改过不嫌晚。()3) 当too 前面有only, all, but时，意思是：非常... 等于very。例如：I'm only too pleased to be able to help you. 能帮助你我非常高兴。He was but too eager to get home. 他非常想回家。11. 不定式的特殊句型so as to1) 表示目的;它的否定式是so as not to do。例如：Tom kept quiet about the accident so as not to lose his job.汤姆对事故保持沉默是为了不丢掉他的工作。Go in quietly so as not to wake the baby.轻点进去，别惊醒了婴儿。2)　表示结果。例如：Would you be so kind as to tell me the time? 劳驾，现在几点了。12. 不定式的特殊句型Why not&Why not +动词原形&表达向某人提出建议，翻译为：&为什么不......?& &干吗不......?&。例如：Why not take a holiday? 干吗不去度假?13.不定式的时态和语态1) 一般式表示的动词，有时与谓语动词表示的动作同时发生，有时发生在谓语动词的动作之后，例如He seems to know this. 他似乎知道这事。I hope to see you again. = I hope that I'll see you again.　我希望再见到你。2) 完成式表示的动作发生在谓语动词表示的动作之前。例如：I'm sorry to have given you so much trouble. 很抱歉，给你添了那么多的麻烦。He seems to have caught a cold. 他好像已经得了感冒。3) 进行式表示动作正在进行，与谓语动词表示的动作同时发生。例如：He seems to be eating something. 他好像正在吃什么东西。4) 完成进行式表示动作从过去开始并延续至说话的时候。例如：She is known to have been working on the problem for many years. 我们知道她研究这问题有好几年了。14. 动名词与不定式1)动名词与不定式的区别：动名词表达的是： 状态，性质，心境，抽象，经常性，已发生的不定式表达的是： 目的，结果，原因，具体，一次性，将发生的2)有些动词如continue接不定式或动名词作宾语，意义基本相同。3)有些动词如continue接不定式或动名词作宾语，意义大相径庭。常见的，下一节有专门讨论第八章 分词一.概念:分词分为现在分词和过去分词两种,是一种非谓语动词形式二.相关知识点精讲:1.现在分词的用法：1) 做表语：He was very amusing.That book was rather boring.很多动词的现在分词都可以作表语：exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.2) 作定语：上面所出现的现在分词都可以用作定语, 修饰一个名词：That must have been a terrifying experience.I found him a charming person.现在分词短语还可以放在名词的后面修饰名词, 相当于一个定语从句：There are a few boys swimming in the river.There is a car waiting outside.3) 作状语：现在分词短语可以表示一个同时发生的次要的或伴随的动作：Following Tom, we started to climb the mountain.Opening the drawer, he took out a box.Taking a key out of his pocket, he opened the door.现在分词短语还可以表示原因, 相当于一个原因状语从句：Not knowing her address, we couldn't get in touch with her.Being unemployed, he hasn't got much money.现在分词短语还可以表示时间, 相当于一个时间状语从句：Hearing the news, they all jumped with joy.Returning home, he began to do his homework.Jim hurt his arm while playing tennis.Be careful when crossing the road.Having found a hotel, we looked for somewhere to have dinner.Having finished her work, she went home.4)作宾补：现在分词在一些动词之后可以做宾语的补语：例如, see, hear, catch, find, keep , have 等.I see him passing my house every day.I caught him stealing things in that shop.I smelt something burning.She kept him working all day.2.过去分词的用法：1) 作表语：We were so bored that we couldn't help yawning.She felt confused, and even frightened.They were very pleased with the girl.I'm satisfied with your answer.He is not interested in research.2) 作定语：She has a pleased look on her face.The teacher gave us a satisfied smile.cooked food a written reportfried eggs boiled waterfrozen food armed forcesrequired courses fallen leavesfinished products a forced smilethe risen sun new arrived visitorsWhat's the language spoken in that country?They're problem left over by history.The play put on by the teachers was a big success.Is there anybody injured?Do you know the number of books ordered?3)作状语：Seen from the hill, the city looks magnificent.Given good health, I hope to finish the work this year.They came in, followed by some children.Depressed, he went to see his elder sister.When treated with kindness, he was very amiable.4)作宾补：过去分词也同样可以作宾语的补语， 接在某些动词后面I will have the clothes washed tomorrow.When they get back home, they found the room robbed.三.巩固练习1. __________ with the best students, I still have a long way to go.A.
