相互区别

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.

区别联系

1 动名词与不定式的区别

动名词表达的是:状态,性质,心境,抽象,经常性,已发生的 不定式表达的是:目的,结果,原因,具体,一次性,将发生的

2 接不定式或动名词,意义相同

3在下列情况下,一般要用不定式:

①hate,like,love前有would(should)时,如:I'd like to have a cup of coffee.

②当谓语动词begin,continue,start等是进行式时,如:The students are starting to work on the difficult maths problem.

③begin,continue,start与know,understand等状态动词连用时,如:I soon began to understwhat was happening.

⒋advise,allow,encourage,forbid,permit等动词后接动名词作宾语,或带不定式作宾语补足语。如:

Our teachers don't permit our/us swimming in the lake.

Our teachers don't permit us to swim in the lake.

4 部分动词后接不定式或动名词时,意义差别较大,应根据句子语境选择使用。

①forget,remember,regret后接不定式,表示现在或未来的动作,接动名词表示动作已经发生。如:

Don't forget to post the letter for me.

Have you forgotten meeting her in Beijing Airport?

Remember to close the windows before you leave.

I remember writing him a letter a year ago.

We regret to tell you that all of you are not invited toattend the meeting.

They regretted ordering these books from abroad.
