不带to的不定式用法
不定式什么时候不带to

动词不定式何时不带to?在英语中,常见的不定式是带to的不定式,但在某些情况下,要使用不带to的不定式。
关于这类不带to的不定式,在使用时极易出错,因此,只有经常注意分析此类语言现象,才能达到正确理解的目的。
现将不带to的不定式的几种情况列举如下:一、在“动词+宾语+不定式”结构中,如果动词是表示感官意义的,如see,feel,hear,observe,notice,watch,listen to,look at等等,其后作宾语补足语的动词不定式结构不带to。
例如:Did you see him go into the house?你看到他进入那座房子了吗?She looked at(watched)other people play basketball.她在观看别人打篮球。
I didn't notice anyone enter the room.我没注意到有人进入那房间。
He listened to us talk.他听我们谈话。
二、在使役动词make,let,have等之后,作宾语补足语的不定式结构不带to。
例如:John made her tell him everything.约翰叫她把一切事情都告诉他。
The soldier had him stand with his back to hisfather.士兵要他背对他父亲站着。
Let me do it.让我来做。
注意:当这类动词转换为被动语态时,后面不带to的动词不定式要转换为带to的动词不定式(但have一般不用于被动句)。
但当句子的动词为let时,to仍可省略。
例如:The boy was seen to go into the house.有人看到那男孩走进那座房子。
They were made to work day and night.他们被迫日夜干活。
The prisoners were let go.罪犯被释放了。

3)在do nothing/anything/everything but(except)结构中。
例如:Last night I did nothing but watch TV.昨天晚上,我除了看电视别的什么也没有干。
但是,如果谓语动词不是“do nothing,anything,everything”,那么but(except)所跟的不定式则仍须带。
