Question

【題目】Had I known about this computer program, a huge amount of time and energy__A__.

A. would have been saved B. had been saved

C. will be saved D. was saved

Answer 1

【答案】A

【解析】

根據(jù)句子的倒裝特征判斷此處是省略了if的虛擬語氣, 原形是：If I had known about this computer program, a huge amount of time and energy .故選擇A。句意為：如果我早知道這個(gè)電腦程序, 就可以節(jié)省大量的時(shí)間和精力了。
