英语语法问题
是这个,much of the research has already been completed为什么用单数谓语动词?this kind of books这个后面为什么接单数谓语动词?men of this kind这个后面为什么接复数谓语动词?

1 much of the research has already been completed 因为research是不可数名词,much of the research 是说研究的大部分,所以还是属于不可数的,因此谓语只能用单数形式.
2 this kind of books 它主要说明的是kind,表示这一种书,所以只能用单数谓语动词.
3 men of this kind 它的主语是位于of前面的men,而不是kind,所以只能用复数谓语动词.
因此,在这种由kind 和 of 组成的主语存在于句子中的时候,我们要把of前面的那个名词作为真正主语,然后再去判断谓语动词的单复数.
再问：好的好难哦哦
