2017-03-30 04:47:00 来源:北外网课

相信对于很多英语六级考生而言,动词不定式早已是一个耳熟能详、手到擒来的问题。但你知道吗,在英语中还存在很多不带to 的不定式,也是英语六级的重中之重。今天,北外网课(北京外国语大学网络课堂)老师也对这些知识点进行了梳理,一起学习一下吧。

在“动词+ 宾语+不定式”结构中, 如果动词是表示感觉意义的see,hear, watch, smell, feel, notice, 或是表示“致使”意义的 have, make, let, 其后的不定式结构不带to.

John made her tell him everything.

这类结构转换为被动语态时,后面的不带to 的不定式一般还原为带to 的不定式.

She was made to tell him everything.

had better,had best, would rather, would sooner, would just as soon, might (just) as well,cannot but 等搭配之后, 动词不定式也不带to.

They cannot but accept his term.

I’d rather not have eggs and bacon for breakfast.

make do,make believe, let drop, let fall, let fly, let slip, let drive, let go of, letthere be, hear say, hear tell, leave go of等固定搭配中, 用不带to的动词不定式.

I’ve heard tell of him.

John let fly a torrent of abuse at me.

在动词help(help +宾语)之后可用不带to的不定式, 也可用带to的不定式.

Can I help (to) lift this heavy box?

在介词except,but 之后, 如果其前有动词do的某种形式, 不定式一般不带to, 反之带to.

There’s no choice but to wait till it stops raining.

Smith will do anything but work on a farm.

There is nothing to do except wait till it stops raining.

连词 ratherthan, sooner than 置于句首时, 其后的不定式不带to.

Rather than push the book back as he wanted to do, he forced himselfto pick it up.

出现在句中其他位置时, 其后的不定式有时带to, 有时不带to.

The manager believes it is important to invest in new machineryrather than to increase wages.

He decided to write rather than telephone.

用作补语的动词不定式, 如果主语是由“all + 关系分句”,“thing+关系分句”,“what分句”或“thing +不定式结构”等构成,并带有do的某种形式,这时,作为主语补语的不定式可以省to,也可以不省.

The only thing I can do now is go on by myself.

What he will do is (to) spoil the whole thing.

The thing to do now is clear up this mess.

All you do now is complete the form

The least I can do is drive everybody else closer to the issue.
