Question

【题目】You can see eighty percent(百分之) of the class ____ most of the work. The rest of the work ________ really difficult.

A. is doing, isB. are doing, areC. are doing, isD. is doing, are

Answer 1

【答案】C

【解析】

句意：你可以看到百分之八十的学生正在做大部分的工作。剩下的工作真的很难。

考查系动词辨析。前句是宾语从句，从句主语eighty percent of the class（百分之八十的学生）是复数人称，系词需用are，可排除AD两项；后句 The rest of the work是单数人称，系词需用is。根据句意结构，可知选C。
