There ______ no answer
keys in this book is a disadvantage.
A. is B. are C. be D. being
如何选?为什么不用 are?
There ______ no answer keys in this book is a disadvantage.
A. is B. are C. be D. being
你要注意到句子后面的动词 is,它才是句子的谓语动词,所以空格应填非谓语动词 being。
句意:该书没有题目答案是个缺点。
多说一句吧,如果要填 are 的话,也不是不可以,则需要在句首添加连词 that,使之变成主语从句,即:
正:There being no answer keys in this book is a disadvantage.
正:That there are no answer keys in this book is a disadvantage.
