A.walksB.walkedC.was walkingD.had walked

Answer 1

【答案】C

【解析】

句意：老人在路上走著，卡車突然把他撞倒了。

考查動(dòng)詞時(shí)態(tài)。A. walks一般現(xiàn)在時(shí)；B. walked一般過去時(shí)；C. was walking過去進(jìn)行時(shí)；D. had walked過去完成時(shí)。when引導(dǎo)的時(shí)間狀語從句，從句是一般過去時(shí)，主句是過去進(jìn)行時(shí)；表示當(dāng)從句的動(dòng)作正在發(fā)生時(shí)，主句的動(dòng)作發(fā)生了。故選C。
