动词不定式在名词后的作用

如题所述

1 、不定式作表语

不定式可放在be动词后面,形成表语。例如:

My work is to clean the house every day.

His dream is to be a teacher.

2、 不定式作定语

不定式做定语通常要放在被修饰的词后。例如:

The next train to arrive was from NewYork.下一列到站的火车是从纽约开来的。

He was the first guest to arrive.他是第一个到达的客人。

扩展资料:

不定式与介词"to"区别

to 有两种用法:

一为不定式+动词原形;

一为介词+名词动名词,to 在下面的用法中是第二种,即to+ 名词/动名词:

admit to承认,confess to承认,be accustomed to 习惯于,be used to 习惯于, stick to 坚持, turn to开始,着手于, devote oneself to 献身于, be devoted to 致力于, look forward to 盼望,pay attention to 注意

介词but,except,besides+to do(do)

在这种句型中,如介词前有动词do,后面应接不带to的不定式;如无do,则接to不定式,即带do不带to, 带to不带do。如:

The enemy soldiers had no choice but to give in.

On Sunday afternoon I had nothing to do but watch TV.
