A．did he begin       B．had he begun      C．he began          D．he has begun

 

Answer 1

【答案】

A

【解析】

試題分析：句意：直到他離開家，他才意識(shí)到家庭對(duì)于他來(lái)說(shuō)是多么的重要。這里not until放在句首句子，這里的主句用部分倒裝。根據(jù)主句的謂語(yǔ)動(dòng)詞用的是過(guò)去式可知這里空格處也應(yīng)該用過(guò)去式，故選A。

考點(diǎn)：考查倒裝的用法。

點(diǎn)評(píng)：本題難度適中。倒裝句是高中階段必須掌握的語(yǔ)法項(xiàng)目，它分為部分到裝和全部倒裝，情況復(fù)雜，需要考生熟記它們的用法。

即學(xué)即練：—How was the weather then?

—Hardly_____off the plane，when it started to rain.

A.I had stepped                 B.had I stepped

C.I stepped                      D.did I step

解析：B。hardly, seldom等否定副詞位于句首作狀語(yǔ)時(shí)，后面要用部分倒裝，再由句意可知，選B。
