一、after用作介词,是“……时间以后”之意,它通常有两种用法。
1.表示“从过去某个时间算起若干时间之后”,作时间状语,常表示“一段”时间,此时应用过去时。如:
Jim came back to China after two years.两年后Jim回到了中国。
He went to London after three months.三个月后他去了伦敦。
2.表示某个时间、日期或事件以后,这时的时间状语常表示某一“点”时间,时态可以根据实际情况用过去时或将来时。如:
After lunch he went out for a walk.午饭后他出去散步了。
He will be back after four o’clock.他将在四点钟以后回来。
另外,after还可以表示:
1.位置“在……以后”(但值得注意的是,表位置时,用behind比用after更普遍)
Shut the door after you.随手关门。
2.顺序“在……以后”
After you,please! 您先请!(口语,客套话)
3.用作连词,表示“在……以后”
He went to bed after he finished his homework.完成作业后,他才上床睡觉。
After what has happened,he won’t go.在发生了这一切后,他不会去了。
二、in用作介词,表示“从现在或说话时刻算起若干时间以后”,作时间状语,常表示“一段”时间,时态常用将来时。如:
I’ll come and see you again in five days.五天后我再来看你。
We’ll come back in a few minutes.我们马上回来。
另外,in还可以表示“在一段时间内”,如:
We have learned 200 English words in the past three years.在刚刚过去的3年里,我们学了200个英语单词。
三、later表示“多少时间以后”,可与after互换,但需要注意两者的位置。具体换法如下:
时间 later→after 时间
Two years later he graduated from middle school.
He graduated from middle school after two years.
两年后他中学毕业了。

1.I’m coming back____nve days.
