现在完成时中的“延续性”问题

现在完成时中的“延续性”问题

英语中有些动词表示的是一种短暂的动作，没有持续性，即“一发生就结束”的动作，这类动词一般称为“非延续性动词”(亦叫点动词或瞬间动词或终止性动词)，在现在完成时中，不能同表示一段时间的状语或How long连用。常见的这类动词有：go, come, leave, arrive, lose, join, borrow, die, begin. 这些动词如果要跟一段时间连用，必须改成相应的具有延续性

a) 非延续性动词可用于现在完成时，但不能与表示一段时间的时间状语连用；

The train has arrived.火车到了。

The train has been here for two hours. 火车到这里已经两个小时了。

The boy has left. 那个男孩走了。

The boy has been away for two days. 那个男孩离开已经两天了。

b) 表示一段时间的时间状语一般为：

①How long…?

②for +一段时间；

③since+一点时间。

c) 非延续性动词的否定形式可以与一段时间连用。

He hasn’t left home for a month.

I haven’t seen you for a long time.
