一道主谓一致的英语题

来源:百度知道 编辑:UC知道 时间:2024/06/07 07:48:38
what we are worrying about _____ her study and work.(be)
我们what引导的主语从句位句首时,主句谓语的单复数取决于表语,这是的表语是her study and work ,那么这里该用is还是are?

填is。可改成:Her study and work is what we are worrying about ;her study and work是一个整体,用单数形式;若将 her study and work改为her study and her work,那么这道题就应该是填 are 了,说到底就是her study and work(单数)和her study and her work(复数)的区别。

我觉得用is

理由是study and work均是不可数名词,两个加一块儿也用单数

is
表语是不可数名词

are

is

is
