Question

【題目】My mother some washing when the telephone rang.

A. does B. did C. is doing D. was doing

Answer 1

【答案】D

【解析】句意：電話鈴響時(shí)，我媽媽正在洗衣服�？疾閯�(dòng)詞時(shí)態(tài)。根據(jù)when當(dāng)…的時(shí)候，它引導(dǎo)的時(shí)間狀語(yǔ)從句，從句一般用一般時(shí)態(tài)，主句用進(jìn)行時(shí)態(tài)。本句從句用一般過(guò)去式，從句要用過(guò)去進(jìn)行時(shí)態(tài)。結(jié)合句意和語(yǔ)境可知選D。
