"after"is often used in the Past Tense. If it is used. In Future Tense, the word which expresses "point of time"is behind it,
After/In
e. g. He paid a short visit to Hangzhou last month but came back again after a
few days.
He will arrive after four o'clock.
Don't hurry, I'll go with you in a few minutes.
He said he would come in a month.
(Bb: in +"lenghth of time" after + "point of time")
3. 从一道题看 go ahead 的用法
请看下面这道题：—Do you mind my taking the books away？—____________ ．
A．Certainly，please doB．No，go aheadC．Yes，not at all D．No，please don't
该题主要考查go ahead在口语中的用法。我们知道go ahead是英语中的一个常用短语，其主要用法有以下几种：
1表示“着手干”（＝begin to do some thing）。
如：The teacher told the students not to write on the papers yet，but John went ahead and wrote his name．老师叫学生先不要在考卷上写字，可约翰已开始写他的名字了。
Once our plan is made，we will go ahead．一旦我们制定了计划，我们就开始工作。
2表示“取得进展”；“取得进步”（make progress）。
如：He has been in the class only a few weeks and he is already going ahead．他来到这个班级才几周就已经取得了进步。
After they settled the problem，they were going ahead fast．解决了问题以后，他们进展得很快。
3．表示“前进”（go forward）；“先进（来）”。如：
Although it was raining hard，they stillwent ahead with their plans．尽管下着大雨，他们仍然继续前进。 You go ahead and tell him that we are coming．你先走一步，告诉他我们随后就到。
4．表示“继续做”（go on with），常与 with连用，后接名词。如：
Let's go ahead with our work．我们继续工作吧。
After a short rest，they went ahead with their experiment．休息了一会后，他们继续做实验。
5含有“毫不犹豫地去做”的意思，常用于口语中，其具体含义要根据句子灵活翻译。
如：—I was wondering if I could use your typewriter．—Sure，go ahead．
—不知是否可以用一下你的打字机。—没问题，请便好了。
If you want to use the bathroom，go ahead．要是你想用浴室，就用吧。
—May I ask you a question？—Yes，go ahead．
—我可以问你一个问题吗？—可以，尽管问吧。
熟悉了以上的用法后，我们便可看出上面那道题中的go ahead属于第五种用法，因此该题的正确答案为B。其意思为:—我把这些书拿走你不介意吧？—不介意，请随便拿吧。
