文档简介
专题精讲精练——不定式
★★★使用易错题点
①不注意语态的变化
误： This job ought to finish well.
正： This job ought to be finished well.
解析：“工作”与“完成”是被动关系，故不定式应使用 to be finished
②混淆点：某些情况不定式表被动含义
在need、require、want等表示“需要”的动词后，可以使用不定式主动表被动
Eg：The room needs cleaning.
2. 在“too…to”结构中
Eg：The box is too heavy to move.
3.在“疑问词+不定式”结构中，不定式可以表示被动的含义
Eg; I don't know what to do.
在“enough+不定式”结构中，不定式可以表示被动的含义
Eg：：The shirt isn't clean enough to wear.
5. 在“there+be”结构中，可以使用不定式主动表被动
Eg：：There is nothing to do.
6.it做形式主语时，主动表被动，常见结构：it is for sb to do sth.★★★某些情况可省略to
1.不定式作表语与to的省略
当主语部分有动词do的某种形式时，用作表语的不定式可以省略to
Eg;All I did was (to) touch the vase, and it broke all of a sudden.
并列不定式与to的省略
当两个或多个作用相同的不定式并列时，通常只需在第一个不定式前用to，其余不定式前的to 可以省略
Eg：I’d like to go to sleep and（to）have a good rest
注意：如果两者有对比关系，则后面不定式前的to不可省略
Eg：To try and fail is better than not to try at all.
3.固定搭配与to的省略
1.let类：
let fall 无意中说出
let fly 发射、攻击
let go 放开
let slip 放走
live and let live 自己活也让别人活
2.make类：
make believe 假装
