1.动词不定式作主语
例如:To finish the work in ten minutes is very hard.
To lose your heart means failure.
★ 动词不定式短语作主语时,常用形式主语it作形式主语,例如上面两句可用如下形式:
It is very hard to finish the work in ten minutes.
It means failure to lose your heart.
注意:当主语和表语都是不定式时,不能用形式主语代替动词不定式。
To respect others is to be respected. 尊重别人就是尊重自己。
To become a slave is to give up one's freedom. 做奴隶就等于放弃自由。
2.动词不定式作表语
不定式作表语可以说明主语的具体内容或表示目的。
His wish is to become an astronaut. 他的愿望是成为一名宇航员。
What he hoped was to be admitted into the university. 他希望能被大学录取。
To live is to do something worthwhile. 活着就是要做一些有价值的事情。
注意: 有些作表语的不定式,在结构上是主动的,但在意义上却是被动的。
She is to blame. 她应该受到责备。
The house is to let. 此房出租。
The result is not long to see. 结果不久就会看到。

(1)不定式可以充当部分及物动词的宾语

在feel, find, make, think, consider等动词后,如果宾语带有宾语补足语时,人们常常用it作形式宾语,而把真实宾语放在宾语补足语之后。
