单元语法全解 熟悉句型 把握要领

现在完成时(3)

本单元的语法重点仍然是现在完成时.在本单元的语法部分,我们总结一下现在完成时的注意事项.

1.如果单纯表示一段时间,或强调一段时间,虽有since从句(一般过去时),主句也可以不用现在完成时.

It is two years since his father died.＝His father has been dead for two years.他父亲已去世两年了.

2.非延续性动词在完成时的否定式中已变成一种可以延续的状态,因此可以表示动作的延续性.

I haven't left here since 1997.自从1997年以来,我一直没有离开过这儿.

3.常见的非延续性动词与延续性动词的转换(主要是指将一个非延续性动词转换成一个延续性动词)

初中阶段常见的需要转换的动词有:

She left her hometown five years ago.她五年前离开了她的家乡.

She has been away from her hometown for five years.她离开家乡有五年时间了.
