时间介词有in , on,at, after, since,during,by,before,after,until等,前三个介词用法有个口诀: at午夜、点与分,上午、下午、晚用in。





1、时间介词in与after 的用法辨析

介词 in + 一段时间用于一般将来时。如:We’ll go to school in two weeks.

介词after + 一段时间用于一般过去时。如:My mother came home after half an hour. 介词after + 时间点常用于一般将来时。如:We’ll go out for a walk after supper.


介词for 表示一段时间如:I have been living here for 10 years.

介词since 表示从过去某一时间以来如:I have been living here since 2000.


介词before表示“在?之前”如:He won’t come back before five .

介词by表示“到?时为止,不迟于?”如:The work must be finished by Friday.


当所指的时间起止分明时用介词during如:He swims every day during the summer. 如果一段时间不明确则用介词for如:I haven’t seen her for years.


till和until用在肯定句中,均可表示“直到?为止”,如:I will wait till(until)seven o'clock.


如:Tom didn't come back till(until)midnight.

till多用于普通文体,而 until则用于多种文体,并且在句子开头时,用until而不用till如:Until he comes back,nothing can be done.

注意:在last, next, this, that, some, every 等词之前一律不用介词。
