Question

The book has been translated into thirty laguages since it ____ on the market in 1973.

A．has come

B．comes

C．had come

D．came

Answer 1

D

試題分析：根據(jù)since引導(dǎo)的從句的時(shí)間狀語(yǔ)in 1973，這是過(guò)去的時(shí)間，所以用一般過(guò)去式，故選D。
點(diǎn)評(píng)：本題難度適中。動(dòng)詞時(shí)態(tài)的考查與一定的語(yǔ)境結(jié)合一起增加了試題的難度，有的考生時(shí)態(tài)的用法背的很熟，但在不同的語(yǔ)境下，就做不對(duì)了，提醒考生一定要會(huì)分析理解語(yǔ)境。
即學(xué)即練：---Has Li Lei finished his work today?
--- I have no idea, but he ______ it when I saw him this morning.
A. had done   B. would do   C. was doing  D. did
解析：C。句意：：--今天李雷完成他的工作了嗎？----我不知道，但我今早看到他時(shí)他在工作。根據(jù)句意及時(shí)間狀語(yǔ)when I saw him this morning可知用過(guò)去進(jìn)行時(shí)。
