after的用法

　after有以后;后来等意思，那么你知道after的用法吗下面跟着我一起来学习一下，希望对大家的学习有所帮助!

after的用法：

　注意after和in的使用：从某时说到多少时间以后，不用after，而用in。如果指“某个时刻，日期或事件以后”，用after。

　He will/would arrive in four weeks

　表达“某事件的若干时间以后”时，应是“若干时间after事件”，而不是“after若干时间of事件”。可说two hours after his arrival，不可说after two hours of his arrival。在“two hours after his arrival”前加不同的介词，有不同的意思:“two hours after his arrival”单用时指“他到达两小时以后”。若前面加the，如the two hours after his arrival指“他到达以后的两小时”，加for指“在他到达以后的两小时全段时间里”，加in 跟没有in意思相同，加within指“在他到达以后的两小时中的某时刻”;

　指“若干时间after日期或月份”时，常把当天的日期或当月除外。如five days after 3 July，指从7月4日算起的5天以后，也就是7月9日。但有例外，five days after I July可能指7月8日，months after July可能指11月，注意避免这种结构产生误解;

　指“从过去的某时或某事说到现在”时，不用after，用since，所以可说Since his graduation he has been abroad(since不可改成after)一定要改的话，可表示为After his graduation he went abroad 这里的after是介词，用作连接词时用法一样。

　He went abroad after he graduated

　不可说 He has been abroad after he graduated

　half after four，five minutes after eight等是美国英语，相当于英国英语half past four，five minutes past eight等，英国方言中也有half after four等表达方式;

　after引导的状语从句，用现在时态，不用将来时态。

　I shall start after he comes

　after常指时间先后的次序，而behind常指位置，如August comes after July，用after,，而A garden lies behind the house，用behind。不过有时after和behind可以通用。

　Please shut the door after/behind you

　He came in after/behind her

　be after指“追求，要求”，

　He is after you

　他正在追求你。

　He is always after me to teach him the violin

　他老是要我教他小提琴。

　after all有时指“虽然这样”，

　In coming home we got caught in the rain and became wet through and through, after all I don't mind as we had a fine time

　不可说be after doing …，这里不是指想要做什么，或是将要做什么，而是已经做了什么。但是可以用after doing…的结构。

　after作为副词时，通常不单用，而是以其他形式出现，如afterwards，then或afterthat。
