untill 是到 直到。。的意思 那么not untill呢? 是什么意思 ?
Not until the child fell asleep did the mother leavethe room. 母亲一直到孩子入睡后离开房间。 这边为什么要使用not untill而不是untill ?
1、表达方式不同
until是till的强调形式,但是它们表达的意义是相同的,都表示"直到某时"。
2、写法不同
当主句是否定句时,它引出的意思是"直到(某时)(某动作)才(发生)" ,这时候常会出现"not until …"的结构,如果将 "not until …"的结构放在句首,那么主句要写成倒装句。
扩展资料:
until 可以放在句首而till则不行。可以说:Until they used up all their money, the young couple were very happy 。却不可以说:Till they used up all their money, the young couple were very happy 。
此两个连词意义相同。肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可 以。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。
Until the child fell asleep, the mother didn't leave the room untill是要用在否定句吗? 看你用好像是这样呀 untill 加后面的did not
追答在其他例句中:
1 Stay here TILL I am back
== Don't leave UNTIL I am back.
2 They went on with their work TILL they finished it
==They didn't stop their work UNTIL they finished it.
3 He didn't leave until yesterday -------- Until yesterday , he didn't leave --------- Not until yesterday, did he leave. (三种句型都有了。)
按照你这边说的 我可以理解为: untill 需要使用在否定句中吗? 因为not untill和untill意思好像是一样的?
