C．hadn't spoken	D．haven't been speaking

Answer 1

C

試題分析：句意，那天，他們又成為了朋友。直到那時(shí)，他們彼此不說(shuō)話已經(jīng)有幾乎兩年的時(shí)間了。根據(jù)題意分析可知他們不說(shuō)話這個(gè)動(dòng)作時(shí)發(fā)生在他們又成為朋友之前，故用過(guò)去完成時(shí)態(tài)，本句中強(qiáng)調(diào)的是他們彼此不說(shuō)話的的事實(shí)，選項(xiàng)A為過(guò)去將來(lái)時(shí)態(tài)，選項(xiàng)B為現(xiàn)在完成時(shí)態(tài)否定式，選項(xiàng)D強(qiáng)調(diào)的是動(dòng)作本身，故不用過(guò)去進(jìn)行時(shí)態(tài).所以選C.
點(diǎn)評(píng)：確定一個(gè)句子的時(shí)態(tài)除了可以通過(guò)時(shí)間狀語(yǔ)以外,還可以根據(jù)上下文來(lái)確定.
