Not until she arrived at the meeting room______she had forgotten to bring the document.
A．she realized
B．did she realize
C．she did realize
D．does she realize
答案
B
解析：直到她到达了会议室，才意识到自己忘了带文件。本题考查倒装句。当某些含有否定意义的副词及连词放在句首时，该句的主谓要倒装，而且是部分倒装，即需要把助动词置于主语之前。所以当not until放到句首时，句子需要倒装。类似的词或短语有：never，seldom，rarely，hardly，scarcely，by no means，in no time，in no circumstances，not only…but also，no sooner…than，hardly…when，等等。参考例句：(1)Not until last week did I get a work permit．(直到上周我才拿到工作许可证)。(2)Not until he told me the truth did I know I misunderstood you．(直到他告诉我真相，我才知道我误解了你)。
