Question

【题目】一I'm tired of cleaning the house.

一 Sweeping robots more and more widely today. Why not buy one?

A. are usedB. were usedC. are usingD. used

Answer 1

【答案】A

【解析】

句意：——我厌倦了打扫房子。——现在扫地机器人的应用越来越广泛。为什么不买一个呢?考查动词语态辨析。Sweeping robots和动词use（使用）是被动关系，需用“be done”被动结构，可排除CD两项。today（今天，现在）用于一般现在时，根据句意结构和语境，可知B项时态错误，故选A。
