【題目】The Russian rocket designer has died. For many years, he ____ as a deputy to the father of Soviet space program.

A. serves B. was serving C. served D. has served

【答案】C

【解析】描述過去所發(fā)生的動作，本句中沒有反應(yīng)出對現(xiàn)在的影響也沒有延續(xù)到現(xiàn)在，故不要使用現(xiàn)在完成時。句意：俄羅斯的火箭設(shè)計師去世了。很多年來，他都充當(dāng)俄羅斯的太空計劃之父的角色。
