Question

【題目】When I came back home, my mother dinner.

A.cooksB.is cookingC.was cookingD.have cooked

Answer 1

【答案】C

【解析】

句意：當(dāng)我回家時(shí)，媽媽正在做完飯。

考查時(shí)態(tài)。A. cooks做飯，一般現(xiàn)在時(shí)；B. is cooking做飯，現(xiàn)在進(jìn)行時(shí)；C. was cooking做飯，過去進(jìn)行時(shí)；D. have cooked做飯，現(xiàn)在完成時(shí)。根據(jù)時(shí)間狀語When I came back home，可知?jiǎng)幼靼l(fā)生在過去的某個(gè)時(shí)刻，主句動詞應(yīng)該用過去進(jìn)行時(shí)，故選C。
