现在完成时有两种情况,即短暂性动作和延续性状态。两者接的时间状语各不一样。

一,短暂性动词不能接since和for,只能在过去式中接过去时间状语。

The old man has died, and he died two years ago. 那个老人已经去世了,他是两年前死的。My brother has joined the army, and he joined it half a year ago.我弟弟已经当兵了,他是半年前参军的。My uncle has left Tianjing, and he left the day before yesterday.我叔叔已经离开天津,他是前天走的。Tom has come back from work, and he came back thirty minutes ago.汤姆已经下班回家了,他是半小时前回来的。Mary has caught a bad cold, and she had it a week ago.I have bought a mobile phone, and I got it three days ago.

二,短暂性动作可以用be动词构成的词组,或其它动词来代替相应的意思,这时可以接since和for

The old man has been dead for two years. 那个老人已经去世两天了。My brother has been in the army since half a year ago.我弟弟已经当兵半年了。My uncle has been away from Tianjing for two days.我叔叔已经离开天津两天了。Tom has been back home for half an hour.汤姆下班回家半小时了。Mary has had a bad cold since a week ago.马丽得重感冒已经一个星期了。I have had the mobile phone for three days.这个手机我已经买了三天了。

了解了两种形式的表达法,以后在写作和语法选择方面,就会轻松很多。

动词时态的学习还需要同学们的练习,只有通过多阅读,多做题,才能巩固所学知识。今天推荐几种语法练习,有利于大家参加各种考试的时候,轻松得高分。
