1. A.
   If it wasn’t for
2. B.
   Were it not for
3. C.
   Had it not been for
4. D.
   If it hasn’t been for

Answer 1

C
試題分析：通過(guò)分析句子，可知其中包含一個(gè)虛擬條件句。根據(jù)主句“would not have been”可看出這是對(duì)過(guò)去情況的虛擬，所以條件句用過(guò)去完成時(shí)。又因?yàn)樘摂M條件句中有had, should, were時(shí)，可以將if去掉，然后把had, should, were提到主語(yǔ)前面，故選C。
考點(diǎn)：虛擬條件句的考查
點(diǎn)評(píng)：注意區(qū)分真實(shí)條件句和虛擬條件句，真是條件句實(shí)現(xiàn)的可能性非常大，而虛擬條件句往往指不能實(shí)現(xiàn)的或純屬假想的情況。
