高考英语求详解 After_____ seemed a long time ,they finally arrived at the destination.

已经知道答案是A...after作介词,故后接宾语从句.
我的疑问是:当after作连词时,不是可以选it吗?为什么不行呢?

解答
当然不能选it.正如你所说,after是介词,后面接的是宾语.介宾短语做修饰.——————seemed a long time后面缺少主语,what可以在宾语从句做主语,符合题意.而如果选择了it,后面成了一个完整的句子.英语语法中不存在介词+完整句子的形式.如果把after去掉了,将这句话逗号改为句号.才可以选it.那如果after作连词呢不是可以接句子吗after 后面不能直接接句子,要接词组或从句。你听过after a long time.接的是一个名词短语对不对。但你一般说after it is a long time 么?多余了。after作连词时怎么用after作连词,引导时间状语从句,表示“在……之后”。以after引导的时间状语从句,既可以放在主句之前,也可以放在主句之后。如果从句放在主句之前,一般要用逗号把它与主句隔开。 ①I’ll call you after I have spoken to them. 我和他们谈过以后会打电话给你。 ②Several years after they’d split up, they met again by chance in Paris. 他们离婚几年后在巴黎偶尔遇见了。 ③After the work was done, se sat down to sum up experience. 做完工作,我们坐下来总结经验。 ④I found the letter long after he had gone away. 他走后很久我才发现了那封信。
