this kind of cimputer is very expensive computer of this kind are very expensive请问,为什么第一个用is,第二个用are?this kind of computer is very expensive 和computer of this kind are very expensive

问题描述:

this kind of cimputer is very expensive computer of this kind are very expensive
请问,为什么第一个用is,第二个用are?
this kind of computer is very expensive 和
computer of this kind are very expensive

问题在于第一个主语是kind,种类,单数,所以is。第二个主语computer,一个种类的电脑有很多,所以复数。

第二句主语应该是:
computers of this kind ,中心词是computers名词复数,谓语用复数
第一句主语是单数,中心词是kind,谓语用单数
