初中英语后面要加不定式的短语

1.can,could,may,should,might,must,ought,need,have,let,make,help sb+do sth.

2.want,would like,like,love,be going to,go on,hate,begin,continue,start,ask,tell,afford,agree,aim,appear,arrange,believe, care,choose,claim,come,consent,dare,decide,demand,desire,determine,decline, expect,elect,fail,offer,happen,seem,refuse,wait,pretend,promise,wish,hope, mean,long,learn,seek,intend,tend,manage,prepare,remember,forget,plan.等可以用与接不定式(to do)，但其中有些词也可以接别的形式，比如动名词等形式(doing)．

3.可以用于”动词＋宾语＋不定式”的词．(即:v.+sb/sth+to do)
advise,allow,appoint,believe,cause,compel,consider,drive,get,guess,invite, judge,know,report,select,state,trust,intend,say,teach,want,beg,warn,expect, intend,pretend,understand,order,send,remind,judge,like,find,force,forbid, encourage.等词可以用于此结构。

4.doing: start/begin/keep/feel like /practice/like/allowed/pay attention to /be used to/consider +doing sth.(所有介词后面都加doing sth.)
see/hear/find/watch sb. doing sth
keep/prevent/stop+from doing sth

1. 聘it作形式定语

动词不定式作宾语且过长时常请it作形式宾语，而让真正的宾语——不定式断后。例如：

The man downstairs found it hard to fall asleep.

2. 小品词to 的回避与复出

许多动词如teach，ask （要；让），tell，beg 等后常有带to的动词不定式作宾补；但let，have，make （让；使），feel，hear 等后作宾补的不定式结构，to 要回避。但在被动语态里to须“重出江湖”；help 后作宾补的不定式可加to，也可省略to.例如：

The policeman made the young woman move her car.

The young woman was made to move her car by the policeman.

[提示] 对不定式进行否定可在其前加not.如：let sb not do sth； tell sb not to do sth. 把直接引语为祈使句的句子变为间接引语，直接引语一般转换成不定式作宾补。例如：

The policeman said. “Don’t play football in the street，children！”

The policeman asked the children not to play football in the street.

3. 回答原因，作目的状语

不定式（短语）常跟在come， go， run， hurry 等动词后作目的状语；或以“in order to +动词原形”、“so as to +动词原形”等形式出现，或回答what . . . for？ / why . . . ？问句。例如：

-Hi， Peter！ Why are you in such a hurry？

-To catch the 7：30 train.

[提示] 有时目的状语可置于句首，意为“为了……”，相当于in order to.例如：

To catch the bus， you must get up early.

在stop后的动词不定式其实是作目的状语，意为“停下来做另一件事”。例如：

Let’s stop to have a meal. I know a good restaurant near here.

4. 作状语，简化相应的复合句

作结果状语的不定式常以“enough to . . . ，only to . . . ， too . . . to . . . ”等形式出场，并能简化成so . . . that . . . 句式。例如：

Liu Mei was so lucky that she received many books from Project Hope.

Liu Mei was lucky enough to receive many books from Project Hope.

5. 作后置定语

作定语时，不定式（短语）常置于被修饰的名词、不定代词等之后。例如：

Now China is the third country to send its astronauts into space after Russia and the US.

[提示]如果不定式（短语）是不及物动词，其后应有必要的介词/副词。例如：

I found a nice place for him to live in.

6. 不定式be to do sth可表将来

be to do sth 表将来，意为“将要做某事”。例如：

Our train is to leave at eight.

7. 时代弄潮儿——“疑问词+不定式”

“疑问词+不定式”结构中的疑问词包括疑问代词which， who （m）， what 和疑问副词how， when， where 等，并常简化相应的从句，但当主句与从句的主语不一致时，不定式常用被动形式。例如：

The little girl wanted to know when her father could take her to Pairs.

The little girl wanted to know when to be taken to Pairs by her father.

第一个回答的太多了吧

refuse to do
like to do
stop to do
start to do

take measures to do
