(完整word版)沪教牛津版八年级下期中语法复习

一、动词不定式

动词不定式的基本结构为“to do sth”（有时可以省略to）,在句中除了不能充当谓语外其他成分都可以充当，如主语、表语、宾语、状语、宾语补足语、定语等，这学期我们主要学习动词不定式作宾语、宾语补足语和目的状语。

1.作宾语

需要用动词不定式做宾语的动词有：

want, hope, wish, like ,begin,start, forget, remember, need, ask, learn, decide, would like, try, offer, plan, refuse, agree, help等。

Remember to post the letter.

I hope to stay with you

拓展：

（1）当作宾语的不定式后跟有宾语补足语时，通常需要形式宾语it代替不定式，并将真正的宾语（不定式）置于宾语补足语之后，其结构为：主语+谓语+it+宾语补足语+动词不定式。

I find it difficult to learn Japanese well.

（2）当两个或两个以上的不定式连用时，后面的不定式往往省略to.

He began to read and write after dinner.

（3）动词不定式可以和疑问词who(m), which, what, when, how, where(why除外)等连用，构成动词不定式短语，在句中作主语、宾语或表语等。

How to control the water pollution is a big problem.

The trouble is whom to invite.

（4）”疑问词+动词不定式（短语）”作宾语时，相当于一个宾语从句

I don’t know what to do next time.= I don’t know what I should do next time.

2.作宾语补足语

动词不定式作宾语补足语时，放在宾语的后面，表示宾语是什么或者怎么样。其后接带to的不定式作宾语补足语的动词（短语）有：

ask, tell, like, love, hate, would like, order, teach, want, wish, advise等。

The doctor advised him to take a good rest.

We asked him to sing a pop song at the party.

拓展：

（1）动词不定式作宾语补足语时，在使役动词和感官动词后面需要省略to，常见的此类动词有：have, let, make, feel, hear, notice, see, watch.

The boss made the workers work over 10 hours a day in the past.

I saw Li Lei fall down from his bike,

（2）help接动词不定式作宾语补足语时，不定式符号可以省略也可以不省略。

He often comes to help us (to) do some farming work.

3.作目的状语

动词不定式表目的时，可放在句子的前面，也可以放在句子的末尾，但在句子前面时，动词不定式常用逗号与句子隔开，而在句子末尾时一般不用逗号隔开。

He goes there to enjoy the fresh air.

主语谓语宾语其余部分

宾语提前做主语，主语变为介词by的宾语，谓语变为be+过去分词，时态根据主动语态来确定。
