Question

【题目】Peter_____ his homework after nine o'clock in the evening.

A.doesn't doB.does notC.isn't doD.isn't doing

Answer 1

【答案】A

【解析】

句意：皮特在晚上的九点以后不做他的回家作业。

考查否定句。do his homework做他的回家作业，其中do是句中的谓语动词，所以变为否定句时要借助助动词do或者does；Peter是第三人称单数形式，所以助动词用does，即Peter doesn’t do his homework after nine o'clock in the evening.故选A。
