1) 作主语
T o learn English is important.
不定式作主语时，谓语用单数。往往用it 作形式主语，把不定式放在谓语后面。如：
It ’s important to learn English.
翻译：我们完成这项工作需要两个小时。
☆☆注意：
在句型结构It is+ adj. of / for sb. to do sth. 的用法。当不定式的逻辑主语和前面的形容词可以构成系表结构时，用of, 否则用 for .
It is impossible for us to get there on time.
It is very kind of you to help us.
It's important ____ us to learn English.
It's friendly ____ you to come and see me.
It's not healthy ___ you to smoke.
It ’s nice ___ you to say so.
It ’s difficult _ us to finish the work.
2) 作宾语
（1） 动词+不定式构成动宾结构。

通常有哪些词只能．．
（2） 疑问词+不定式, 作宾语。如：
I don’t know what to do next/ how to do it next.

☆☆注意：不定式短语作宾语时，如果还带有宾语补足语，往往把不定式短语放在
宾语补足语之后，用it 作形式宾语。如：

翻译:我发觉跟他挺难相处的。

常与动词ask, tell, order ,want ,get, would like, like, advise, invite, allow, help,
wish,warn, 等连用。

翻译：我想要你找汤姆谈谈。
