　　典型例题

　　1)　Why can't I smoke here?

　　At no time___ in the meeting-room

　　A. is smoking permitted　　B.　smoking is permitted

　　C. smoking is it permitted　D.　does smoking permit

　　2) Not until the early years of the 19th century ___ what heat is.

　　A. man did know　 B. man know　 C. didn't man know　 D. did man know

　　答案D.　 看到Not until…的句型，我们知道为一倒装句，答案在C，D 中选一个。
