Question

_______ Anirban Maitra, a professor at Oxford University, Jack’s success would not have been possible.

A．If it wasn’t for

B．Were it not for

C．Had it not been for

D．If it hasn’t been for

Answer 1

C

解析試題分析：通過分析句子，可知其中包含一個虛擬條件句。根據(jù)主句“would not have been”可看出這是對過去情況的虛擬，所以條件句用過去完成時。又因為虛擬條件句中有had, should, were時，可以將if去掉，然后把had, should, were提到主語前面，故選C。
考點(diǎn)：虛擬條件句的考查
點(diǎn)評：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。
