考点聚焦
动词与介词、形容词与介词以及介词与名词等所形成的搭配结构，是介词考查的重点，也是考生学习时的一个难点。对于搭配问题，首先要理解不同介词的含义，在此基础上要强化记忆，记准搭配结构。
3.Scientists are convinced__the positive effect of laughter__physical and mental health.
A.of;at B.by;in C.of;on D.on;at
[C]考查动词convince的介词搭配convince sb. of sth.及名词effect和介词的搭配have an effect on sth.。要特别注意的是，还有一些动词，如:rob,remind等，都有相似的结构，rob/remind sb. of sth.。“他抢了我的钱”，要表达为“He robbed me of my money”，而不能只顾中文思维，错误地说成“He robbed my money”。

4.The better use you can make__time,the greater contributions you will make__society.
A.in;to B.on;for C.of;to D.in;on
[C]考查两个动词词组make use of sth.和make contribution to sth.

Human facial expressions differ from those of animals in the degree__they can be controlled on purpose.
A.with which
B.to which
C.of which
D.for which
[B]本题表面上看是考查定语从句，而实质上却是考查介词的使用，即to some/the degree“某种程度上”。

好了，接下来非谓语动词~

五.非谓语动词
1.The three men tried many times tosneakacross the border into the neighboring country,__by the police each time.

下午加油来更~！

1.动词不定式一般式表示的动作可能与谓语动词的动作同时发生，也可能在之后发生。例如:I saw the young man enter the house.(同时发生)
I hope to go there next time.(之后发生)
2.动词不定式完成式表示的动作在谓语动词之前发生。例如:I`m sorry to have broken your glasses.
动词不定式进行式表示的动作与谓语动词同时发生。例如:When he came in,I happened to be reading at the table.

4.动词不定式的被动式有两种形式:to be done表示将要被做，to have been done表示已被做。例如:The new cinema to be put up next year will be very large.
The cinema is said to have been built last year.

困了。。

突然发现需要码的很多很多诶~

5.在表示情绪的动词，如like,love,hate等后，用动名词做宾语表示一般倾向，用动词不定式表示特定某事;但在would/should like/love,prefer后要用动词不定式。例如:I hate eating the same food every day.
Would you like to watch TV in the evening?

6.在动词need,want,require后用动名词表示被动含义，相当于动词不定式的被动式;而用动词不定式的主动式则表示主动含义。例如:The house needs cleaning.=The house needs to be cleaned.
He needs to clean the house first.
7.在介词后一般用动名词做宾语，但在少数介词，如but,except后用动词不定式做宾语，但要注意to的省略:如but前有do则省去to。例如:I have done nothing but help him with his luggage.
I have no choice but to wait for him at the bus stop.

8.分词的完成式一般不用来做定语，因此，要表示主动，完成的意义常用定语从句。例如:The accident which happened yesterday was very serious.
9.如果分词短语的逻辑主语与句子不同，则要用从句或分词独立主格结构来表示。例如:Weather permitting,we will go to the Central Park.
10.分词做状语时，分词的逻辑主语要与句子的主语相一致。若他们之间的关系是主谓关系，用现在分词，而动宾关系则用过去分词。如果分词的动作先于谓语，分词要用完成式。例如:Having finished his composition,he went home.
While looking through the paper,he found some errors.
