Question

【題目】More than 20 people ________ in traffic accidents ________ last May.

A. have died, for B. have been dead, since

C. have died, since D. have been dead, for

Answer 1

【答案】B

【解析】

試題分析：since在引導(dǎo)時(shí)間狀語(yǔ)時(shí)，后面接時(shí)間點(diǎn)；for在引導(dǎo)時(shí)間狀語(yǔ)時(shí)，后面接一段時(shí)間。根據(jù)下文last May即可斷定選B。句意：自從去年五月以來，超過20人死于交通事故。結(jié)合語(yǔ)境可知本句描述的是現(xiàn)在已經(jīng)完成的動(dòng)作，用現(xiàn)在完成時(shí)態(tài)。
