Question

【題目】Since Jack was laid off from his job three months ago, he _____ a new one, but without luck.

A. looked for B. had looked for

C. has been looking for D. is looking for

Answer 1

【答案】C

【解析】

考查時(shí)態(tài)。句意：自從杰克三個(gè)月前被解雇后，他一直在找個(gè)新的工作，但是不走運(yùn)。時(shí)間狀語是since引導(dǎo)的，主句應(yīng)該是現(xiàn)在完成時(shí)或現(xiàn)在完成進(jìn)行時(shí)，這里強(qiáng)調(diào)動作一直在進(jìn)行而且可能還要進(jìn)行下去，用現(xiàn)在完成進(jìn)行時(shí)，故選C。
