not…until…怎么译比较好?

直到。。。才。具体用法倒装句之部分倒装 部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词,则需添加助动词do,does或did,并将其置于主语之前。句首为否定或半否定的词语,如no,not,never,seldom,little,hardly,at no time,in no way,not until… 等。Never have I seen such a performance。Nowhere will you find the answer to this question。Not until the child fell asleep did the mother leave the room。当Not until引出主从复合句,主句倒装,从句不倒装。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 答案A。这是一个倒装问题。当否定词语置于句首以表示强调时,其句中的主谓须用倒装结构。这些否定词包括no,little,hardly,seldom,never,not only,not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time。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。改写为正常语序为,Man did not know what heat is until the early years of the 19th。现在将not提前,后面就不能再用否定了,否则意思就变了。
