1、Until可用于句首,而till通常不用于句首。
Until you told me, I had heard nothing of what happened.直到你告诉我以前,出了什么事我一点也不知道。
2、与 not 连用时,情况不一样
until 前面加not一般翻译成直到才(开始)?
I didn‘t go to bed until my mother come back。直到我妈妈回来我才去睡觉。(回来时才开始去睡觉)
till 不与not连用,一般翻译成直到才(结束)?
I finish my homework till my mother come back。直到我妈妈回来我才完成了作业(回来时已经结束)?
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至某时才做某事"。翻译时需判断句中的动词该用肯定式还是否定式。
例:
肯定句:
I slept until midnight. 我一直睡到半夜时醒了。
Wait till I call you. 等着我叫你。
否定句:
She didn't arrive until 6 o'clock.她直到6点才到。
Don't get off the bus until it has stopped.公***汽车停稳后再下车。是"直
扩展资料
Not until …在句首,主句用倒装。
Not until the early years of the 19th century did man know what heat is.直到19 世纪初,人类才知道热能是什么。
Not until I began to work did I realize how much time I had wasted.直到我开始工作,我才认识到了我已蹉跎了几多岁月。
并列连词:
when、while、 till、until、 since、after、 before、 as soon as 等是连接时间状语从句的连词。在时间状语从句中要特别注意时态的搭配:当主句是将来时,从句要用一般现在时。
