We ________ thank the young man.Without his help ,we can not
3个回答

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)
