题目内容
Only when I checked the paper once more _________ there was a mistake.
A.I realized B.did I realize C.I had realized D.had I realized
B
【解析】
试题分析:句意:只有我再次检查试卷时才意识到有一个错误出现了。这是倒装句,Only+状语从句放在句首时,主句用部分倒装。检查时发现的错误,检查和意识到几乎同时发生所以用过去式,故选B。
考点:考查部分倒装的用法。
点评:本题难度适中。本题对已学语法知识点的回顾,需要考生熟记倒装的各种情况。
即学即练:Only then ________ the importance of English.
A. I realized B. did I realize C. I had realized D. had I realized
解析B:。在句首的only如果后面跟了副词、介词短语或从句等状语,则主句用倒装结构。如only后跟的是主语,就不用倒装结构了。
