问题描述：

答案A为什么,C为何不可以?
If you want to improve your listening skills,you should often _____tapes after class.
Alisten to B listen C listens to D hear

答

是因为 you。
i, you, we, they 后面的动词没有(s).
所以不可以放C.

答

should是情态动词

答

should是情态动词，情态动词后面的动词必须用原形

答

should 后面跟动词原形

答

因为you不是第三人称

答

should 后边要接动词原形啊！！！

答

C 是动词第三人称单数形式,这里是情态动词should之后,不论人称都是动词原形.

答

should是情态动词，后面应该+动词原形，所以选A不选C
