延续性与非延续性动词在现在完成时态中的使用
延续性动词和非延续性动词在现在完成时态中的使用有一些区别。

1.延续性动词：
延续性动词表示持续的动作或状态，常见的有live（住）、work
（工作）、study（学习）、wait（等待）等。

在现在完成时态中，延续
性动词通常用来表示一个动作或状态开始于过去，持续到现在，并且可能
会继续下去。

10年了。

态中，非延续性动词通常用来表示一个动作已经完成或一个状态已经发生，没有持续的时间。

例如：
- She has arrived at the airport.（她已经到达了机场。

- The project has finished.（项目已经完成了。

比如，动词sleep（睡觉）可以是延
续性动词，表示持续的睡眠状态，也可以是非延续性动词，表示一次性的睡眠动作。
