情态动词和助动词后加not,变否定句时需在系动词be、情态动词和助动词时1.
简单句中含有系动词be
2.简单句中谓语动词为行为动词时,要根据时态选用do的相应形式,把肯定句变为否定句。
3.祈使句变否定句时,一般在句首加Don*t,但Let us或Let*s开头的祈使句在 Let us或 Let*s后加not即可。
4.主从复合句中,主句是I think,I believe等结构,变否定句时,形式上否定主句,实际上否定从句。
5.“had better +动词原形”,变否定句时为“had better not +动词原形”。
6.动词不定式变否定式时,常在不定式to前加not。
7.使役动词和感官动词(make,let,hear,see,watch等)后接省略to的不定式,此种不定式变否定句时只需在省略to的动词原形前加not。

fu movie of all time,Enter the Dragon(1973).Tragically however,Lee suddenly and mysteriously died while making his next movie Game

考点分析:
考点1:动词和动词短语
就是表示动作和状态的词。根据其在句中的功能,动词可分为四类,分别是:实义动词、系动词、助动词、情态动词。
动词分类及用法
一、实义动词
& & & & 实义动词又叫行为动词,分成及物动词和不及物动词 。
1、及物动词是必须带宾语的动词,可分为如下两类。 1) 及物动词+宾语例:I love my home. 我爱我家。 He bought an English dictionary. &他买了一本英语词典。 2) 及物动词+间接宾语+直接宾语例:She taught us maths. 她教我们数学。 My mother gave me a new pen. &母亲给了我一支新钢笔。提示:常用的能接双宾语的及物动词有:give, teach, buy, lend, find, hand, leave, sell, show, read, pay, make, offer, build, pass, bring, cook等。
2、 不及物动词不及物动词不需要跟宾语,本身意义完整。例:She came last week. 她上周来的。 It is raining hard. &正下着大雨。 Class began at half past seven. &7点半开始上课。 What happened yesterday? 昨天发生了什么事?
3、同一动词有时可用作及物动词,有时可用作不及物动词。例如:She can dance and sing.   她能唱歌又能跳舞。(sing在此用作不及物动词。)   She can sing many English songs.   她能唱好多首英文歌曲。(sing用作及物动词。)
二、系动词
& & & & 系动词不能单独作谓语,后面必须跟表语构成合成式谓语。表语通常由名词、形容词,或相当于名词或形容词的词或短语等充当,说明主语是什么或怎么样。连系动词有 be, seem, look, become, get, grow, feel, appear, remain, turn。
& & & & 例如:   The story sounds true.   Those oranges taste good.
三、助动词
& & & & 协助主要动词构成谓语动词词组的词叫助动词。 助动词自身没有词义,不可单独使用,只能在实义动词和系动词前构成谓语的时态、语态以及否定式和疑问式。它没有对应的汉译,例如: He doesn't like English. 他不喜欢英语。 (doesn't是助动词,无词义;like是主要动词,有词义) He is singing. 他在唱歌。(is是助动词,无词义,构成现在进行时)
四、情态动词
& & & & 情态动词是一种本身有一定的词义,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等,不能单独作谓语,情态动词后面加动词原形。情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 "not"。常用的情态动词有 :
Can(could) (能,会) 如:I can swim. 我会游泳。   
May(might) (可以) 如: You may go now. 你现在可以走了。  
Must (必须) 如:You must do your homework. 你必须写作业。   
Need (需要) 如:He needs our help. 他需要我们的帮助。
注意:1、情态动词表推测在肯定句中一般用must (一定),can, could(可能),might /may(也许,或许)。否定句中用can’t / couldn’t(不可能)。例如:
It can’t be the headmaster. He has gone to America.  这不可能是校长,他去美国了。
2、can和could表示允许的用法:表示现在的允许时,若是请求别人允许自己做某事,两者均可用,但用could 语气更委婉;若是自己允许别人做某事,一般只用 can,而不用 could。如:   Can [Could] I come in? 我可以进来吗?
3、must和have to的用法   表示必须、必要。(must表示主观多一些而have to则表示客观多一些)如:   You must come in time.   你必须及时过来。   
回答must引出的问句时,如果是否定的回答,不能用mustn't,而要用needn't或don't have to。   — Must we hand in our exercise books today?   — Yes, you must. (No, you don’t have to.)   —我们今天必须交上练习册吗?   —是的。(不,不必。)
4、need表示“需要”或“必须”,作情态动词时,仅用于否定句或疑问句中,后跟动词原形。Need还常用作实义动词,有时态、人称和数的变化,后面通常接名词、代词和带to的不定式,
Do you need a dictionary?   你需要词典吗?
You &needn't give it back before Friday. 你不必在星期五前还我。
& & & & 对于动词的考查,通常会在单选,词语运用和完形填空中出现。除了考查时态和语态外,只要考查实义动词的固定短语,系动词和情态动词的灵活运用。
典型例题:--Must I return the magazine to you right &now,Sandy/
& & & & & --No,you & & & &.you may keep it until next Wednesday.
& & & & A. &needn't & B. &can't & &C. must & &D. may
解析:本题考查情态动词must构成的疑问句的回答方式。否定回答应该用 needn't 。
& & & & 汉语和英语的动词有较大差异,而学习者在学习是往往容易套用汉语,从而混淆意思相近而用法不同的词或词组,也容易混淆词形相近而意思不同的词或词组,例如look for和find, listen和 hear。所以我们在学习中要认真分析不同的词或词组。
典型例题:They had to ___the 800--meter race because of the bad weather.
& & & & & A &put on & B put off & &C &get on & D &get up
解析:本题考查四个动词短语的区别。put on “穿上,戴上”; put off“推迟”; get on “上车”; get up“起床”。根据语境,应选put off。

Last year in the UK at least 45 people died
and 900 more were injured in car accidents where drivers were using their
mobile phones.Yet many
people continue to use them while driving even though it’s
dangerous.
&& Research has shown that it is
difficult to concentrate 0n driving and talking at the same time.It can even be more dangerous than
driving after drinking too much.A recent study found
that when drivers were talking on their mobile phones,their
stopping times were 30 percent slower than when they had drunk too much—and
nearly 50 percent slower than when they were driving normally.It also found that drivers talking on mobile phones were less able
to control their cars than drunk drivers.
&& And talking isn’t even the most
serious problem, texting is. Unbelievably, another recent study reported that
22% of adults admitted
they had sent a text message while driving at least once in the past month.An average text message takes 90 seconds to write and send.That means for one and a half minutes a driver is looking at their
phone’s screen and not at the road.The arrival of new
smart phones such as the iPhone will only make matters worse as they will allow
users to do more things than ever before.
&& Using a mobile phone while
driving puts others’ lives at risk.No matter how well we drive,if another
driver is not being professional or careful,we are put
in danger by their actions.Such drivers are selfish,careless and should have their driving licences(驾照)cancelled.
&&& There is no doubt that
mobile phones call be fun and are extremely useful,especially when you’re in trouble.But there is no need to use them while driving.Just wait until you stop or you will probably get into trouble of
your own.

&&& Paul had business in town
that day and left the builder to his work.When he returned,the builder had just
finished his job.Paul was shocked.Instead of a fence there was a bridge,stretching
from one side of the creek to the other.
&&& As Paul stood on the
bridge,staring in
amazement,his younger brother Jason,came across,and took Paul’s hand.“You are a good man to have built this bridge after a11 I've done,”said Jason.

tears in his eyes,said to the builder who was packing

dirty apple from the ground to eat later on.Prana knows
that when she brings her treasure into the house,I am
not always &38,so she tries to hide it from
