Question

【題目】The kids ________ in the garden when it suddenly began to rain.

A.playB.playedC.are playingD.were playing

Answer 1

【答案】D

【解析】

句意：孩子們正在花園里玩，突然下起雨來。

A. play動(dòng)詞原形；B. played過去式或過去分詞；C. are playing現(xiàn)在進(jìn)行時(shí)態(tài)形式；D. were playing過去進(jìn)行時(shí)態(tài)形式。根據(jù)when it suddenly began to rain.可知，此空應(yīng)填過去進(jìn)行時(shí)態(tài)形式。結(jié)構(gòu)是“主語+was/were+現(xiàn)在分詞”，故填were playing，故選D。
