【題目】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

【答案】A

【解析】

句意：——我厭倦了打掃房子。——現(xiàn)在掃地機(jī)器人的應(yīng)用越來(lái)越廣泛。為什么不買一個(gè)呢?考查動(dòng)詞語(yǔ)態(tài)辨析。Sweeping robots和動(dòng)詞use（使用）是被動(dòng)關(guān)系，需用“be done”被動(dòng)結(jié)構(gòu)，可排除CD兩項(xiàng)。today（今天，現(xiàn)在）用于一般現(xiàn)在時(shí)，根據(jù)句意結(jié)構(gòu)和語(yǔ)境，可知B項(xiàng)時(shí)態(tài)錯(cuò)誤，故選A。
