Wethanktheyoungman.Withouthishelp,wecannotfinishit.A.bothmustB.mustbothC.areboth为什么要选A?

Question

We ________ thank the young man.Without his help ,we can not finish it.
A.both must B.must both C.are both
为什么要选A?

Answer 1

首先确定不是进行时,排除A.
both当形容词的时候,有
both of the boys=both boys =both the boys（两个男孩都...）
接代词的时候是
both of us=we both（我们都...）
当both做副词的时候,放在Be动词,助动词,情态动词之后,行为动词之前
比如说
We both like English.就类似于we both must thank the young man.
We can both sing.
另外,both 也构成短语both...and...（两者都...）
比如Both Tom and Tina like English.（Tom和Tina都喜欢英语）
