题目内容
19.It rained heavily overnight and not until this morning __________.( )A. | had it stopped | B. | did it stop | C. | stopped it | D. | it stopped |
分析 雨下得很大,直到今天早上,它才停.
解答 答案为B
not until+时间状语位于句首主谓应用部分倒装.又因为时态前后一致,故用did it stop.故选B.
点评 部分倒装,部分倒装是指将谓语的一部分如助动词或情态动词倒装至主语之前.如果句中没有谓语,就用助动词或情态动词.否定意义的词放句首用部分倒装英语中构成部分倒装的主要情形有:
1.含否定意义的词(如 never,hardly,seldom,little,few,not until,not,not only,no sooner,no longer,nowhere,by no means 等)置于句首时,其后用部分倒装.如:
Never have I seen read such a book.我从未读过那样的书.
2.only 加状语(副词/介词短语/从句)放在句首时,其后用部分倒装.如:
Only in this way can you do it well.只有这样你才能做好.
3.so/neither/nor 表示前面所说的情况也适合于后者时,用"so/neither/nor+助动词+主语"这样的倒装句式.如:
He can sing English songs and so can I.他会唱英语歌,我也会.
4.当虚拟条件句含有 were,should,had 时,可省略 if,将 were,should,had 置于句首.如:
Were I Tom(=If I were Tom),I would refuse.如果我是汤姆,我就会拒绝.
5.so…that 结构中,将 so+adj./adv.置于句首时,其后要用倒装语序.如:
So cold was the weather that we had to stay at home.天气太冷,我们只好呆在家里.
