被动形式: He preferred to be assigned some heavier work to do.
语法功能： 表示与谓语动词同步发生
2) 完成形式：He pretended not to have seen me.
被动形式：The book is said to have been translated into many languages.
语法功能：表示发生在谓语动词之前
二）不定式常考的考点：
1）不定式做定语----将要发生
2）不定式做状语----目的
3）不定式充当名词功能---To see is to believe.
三)不定式的省略
1)感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel
+ do 表示动作的完整性，真实性；
+ doing 表示动作的连续性，进行性

" 感官动词后面接形容词而不是副词：The cake tastes good; It feels comfortable.
2) 使役动词 have bid make let 等词后不定式要省略但同1)一样被动以后要还原to
I 'd like to have John do it.
I have my package weighed.
Paul doesn't have to be made to learn.
3) help help sb do help sb to do help do help to do
四)有些动词后只跟不定式如：

force sb to do. be more likely to do love to do warn sb to do be able to do

二. 动名词： 具有动作性特征的名词

一)动名词的形式:
一般形式：I don't like you smoking.
完成形式：I regret not having taken your advice.
被动形式：This question is far from being settled.
二) 动名词常考的点
1)动名词做主语谓语动词为单数
2)在动名词和不定式中,做为介词的宾语是动名词
3)动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语.
I would appreciate_______ back this afternoon．（MET 1992）
A．you to call B．you call C．you calling D．you're calling（Key：C your calling 也对）

例外：war and peace is… war and peace是一个整体
