Question

【题目】一Andrew hit a pipe. and filled the room with water.

一Let's help him right away.

A. mopping it up B. mopping up it C. mop it up D. mop up it

Answer 1

【答案】C

【解析】

句意：——安德鲁撞坏了一个水管，房间里充满了水。——让我们马上帮他拖干净。考查动词短语。help sb do sth.“帮助某人做某事”，所以排除A、B选项；mop up是固定短语，意思是“拖干净”，代词作宾语的话应放在两词中间，所以排除D选项；故答案选C。
