新概念英语中多次出现I have bought a house.现在完成时,不是不能使用非延续性动词吗,若能用,何时用?

现在完成时中的非延续性动词的用法.
英语中,有一类为数不多的动词,被称为非延续性动词,也有人将其成为短暂性动词或一次性动词.其实,所谓的非延续性动词只是针对现在完成时态以及过去完成时态而言,有些动词持续时间非常之短,从而不能与时间联用.下列动词均为非延续性动词：
1.come 2.go 3.come 4.arrive
5.buy 6.sell 7.lend 8.borrow
9.give 10.get 11.die 12.return
13.leave 14.begin15.start 16.finish
17.turn on 18.turn off 19.get to
20.get on 21.get off 22.put on
23.take off 24.stop
非延续性动词只与完成时态有关,而与其他时态毫无干系.那么,它们在完成时态中到底怎样使用呢?我们看看下列的总结和归纳：
1.非延续性动词可以用在完成时态的句子中：
(1)He has already come here.
(2)They have ever bought dictionaries.
(3)She has died.
(4)They told me that he had returned the book.
(5)We asked him whether he had got the message.
2.但非延续性动词在完成时态的句子中不能与时间联用：
(1)He has already died for ten years.( X )
(2)They have already come here for 2 days.( X )
(3)I have already bought this car for 3 years.( X )
(4)She has borrowed the book for nearly one week.( X )
(5)I have got this message from him for half an hour.( X )
3.解决方案：
（1）仍然用完成时态,可将非延续性动词改为延续性动词（多用be + 形容词句型或用 had 等延续性动词）
（2）抛弃完成时态,归为一般过去时,动词可不变.
