主要知识点：
1、 情态动词must、could、might、can’t表推测的用法
情态动词
用法
must
表示某事发生的可能性很大
could/might
表示某事发生的可能性不是很大，对某事的发生没有很大的把握
can’t
表示某事不会发生的可能性很大
【例句】:1、You must be tired after working for eight hours without a rest.
2、Don’t play with the knife. It could/might cut your hand .
3、The red bike can’t be Mary’s.Hers is blue.
【注】: 1、情态动词表推测的三种句式：
①在肯定句中一般用must(一定），may(可能，也许），might/could(可
能，也许）
【例句】:He must/may/might/could know the answer to this question.
②在否定句中用can’t/couldn’t(不可能），may not/might not（可能不：
也许不）
【例句】:The man can’t/couldn’t be the headmaster. The headmaster has
gone to America.
He may/might not know the scientist.
③疑问句中用can/could,表示惊讶、怀疑、不相信等。
【例句】:Could he have finished the task ?
Can he be at home now?
【提示】:might,could不是may,can的过去式，而表示语气较为委婉或
可能性较小
2、情态动词表推测的三种时态
①对将来情况的推测，用“情态动词+动词原形”
【例句】:She must/may/might/could arrive before five.
②对现在或一般情况的推测，用“情态动词+be”,“情态动词+be+doing”
或“情态动词+动词原形”
【例句】:He must/may/might/could be listening to the radio now.
③对过去的情况推测，用“情态动词+have+过去分词”
【例句】:The ground is wet. It must/may/might/could have rained last
night.
【提示】:情态动词should/ought to表推测时，意为“按说应该、理
应......”，但与“have+过去分词”连用时，意为“本应该
做某事却没做”
【例句】:It’s seven o’clock.Jack should/ought to be here at any moment.
例：---Look at that girl! Is she Susan?
---No, she ______ be Susan. Susan has gone back to her hometown.
A. mustn’t B. can’t C. needn’t D. wouldn’t
解析：此题考察情态动词的用法。根据句意可知，应用can’t(一定不是）
答案：B
3、含情态动词must的反意疑问句
①陈述部分有must,且表示“必须”时，附加疑问部分用mustn’t, 如果表
示“有必要”则用needn’t
【例句】: We must work hard , mustn’t we ?
The teacher must show concern for each pupil , needn’t he?
②陈述部分中是mustn’t表示“禁止”时，附加疑问部分用must
【例句】:We mustn’t be late, must/may we ?
③陈述部分中的must表示“一定”、“想必”等推测意义时，附加疑问部
分是根据陈述部分的谓语动词或其助动词来定
【例句】:He must be a teacher, isn’t he ?
④must have done是对过去情况的推测，当陈述部分没有明确的表示过去
的时间状语时，附加疑问要用have的相应形式；当陈述部分有明确的
过去时间状语时，附加疑问要用过去时。
【例句】:You must have lived here for a long time, haven’t you?
You must have seen him yesterday, didn’t you ?
2、 whose 疑问代词，意为“谁的”，位于名词之前，作定语修饰名词。
【例句】: ---Whose book is this ?
---It’s mine.
例：“______ bookcase is this?”“It must be ______.”
A. Who’s;Tom B. Who’s;Tom’s C. Whose;Tom’s D. Whose;Tom
解析：根据句意可知第一个空要填whose”谁的”，第二个空要用名词所有格
形式来表示，Tom’s=Tom’s bookcase.
答案：C
3、 belong to 意为“属于”，其主语通常是物，它不能用于进行时和被动语态。
To为介词，后接名词或人称代词的宾格形式，不能接名词性物主代词或名词
所有格。
【例句】: This bicycle belongs to Amy.
例：---Whose guitar is this ?
---It ______ Alice. She plays the guitar.
A. might be B. must be C. can belong D. might belong to
解析：根据句意应先排除A和B，因为它们后面应该用名词所有格形式；belong
to 是固定短语，to不能省略。
答案：D
【注】: The book belongs to Mary.
= The book is Mary’s.
4、anything valuable 意为“贵重的东西”，当形容词修饰something,anything,nothing
等复合不定代词时，形容词要后置。
【例句】: I have something important to tell you.
5、 pick up 意为“捡起；拾起”，它的宾语如果是名词，该名词宾语可以位于pick
和up之间，也可以位于pick up 之后；它的宾语如果是代词，该代词宾语只
能位于pick与up之间。
【例句】: Please pick up the book.=Please pick the book up.
Please pick it up.
【注】: pick up 的其它用法
①（无意中）学会
【例句】:If you go to England you’ll soon pick up English.
②搭载；开车去接
【例句】: The car stopped to pick me up.
③感染；患病
【例句】: Where did you pick up a cold?
例：It seems that the aged people _____ the H7N9 more easily from the recent
Cases.
A. pick up B. mix up C. set up D. use up
解析：此题考查动词短语辨析。Pick up 患病；感染；mix up 混合在一起；
Set up 建立；use up 用完，又根据题意可知选A
答案：选A
6、 有关away短语
run away 逃跑 take away 拿走；带走 stay away 离开
move away 搬走 put away 收起来 give away 捐赠；赠给
例：The old man was very generous. He decided to ______ some of his money to
the people in need.
A. run away B. give away C. move away D. stay away
解析：由句意可知，这位老人很慷慨，他决定把自己的一些钱捐给需要的人。
故give away符合题意。
答案：B
7、 there be+主语+v-ing结构，意为”有......正在做......”，其中v-ing用作定语，
修饰其前面的主语，相当于一个定语从句
【例句】:There are some boys playing football on the playground.
【注】：情态动词可用在there和be中间表推测或判断
例：Listen!There must be someone ________ at the door.
A. to knock B. knocking C. knock D.knocked

答案：选B

to go to bed.
解析：结合本题中的“她昨晚没有睡好”可知，现在她觉得很瞌睡，故填
sleepy., feel(感觉)+形容词
答案：sleepy
9、情态动词+be +v-ing结构，表示推测某个动作正在进行。
【例句】: He could be sleeping at home now.
10、 suit 名词，“西服；套装”，动词，“适合；适宜于”

②suit sb 意为“适合某人”，除了指衣服、鞋子等在花色、款式上适合
某人，也指时间、食物等适合某人。另外suit还可指满足某人需要、
合某人心意。
【例句】: This dress doesn’t fit me.
The dress suits you beautifully.
例：It’s difficult to find a time that ______ everybody.
A. suits B. fit C. suit D. Fits
解析：关系代词that指代先行词time,并在定语从句中作主语，从句
的谓语动词应用第三人称单数形式，首先排除B和C。Fit 常
指大小、尺寸适合；suit除指颜色、款式适合，还可指时间、
款式适合，还可指时间、食物等适合。
答案：A
11、 not only...but also...（不但...而且...）的用法

修饰延续性动词，多指现在的情况与过去相比，故常用于现在时态
