在高中英语语法中，单独考察的题型几乎是没有的，但是语法知识点却贯穿整张试卷，下面小编为大家整理了现在完成时的语法知识，希望可以为大家带来帮助，一起来学习一下吧！

现在完成时

1、表示过去发生的某一动作对现在造成的影响或结果。常用的状语有already, yet, just等。

2、表示过去已经开始，持续到现在，而且还可能继续下去的动作状态。往往和表示一段时间的状语连用，如today, this week, lately, recently, in the past few days, since, for a long time等。

注意：

（1）非延续性动词在肯定句中不能与表示一段时间的时间状语连用。

（2）此类动词在否定句中则可以与表示一段时间的时间状语连用。这类动词有：begin, leave, go, borrow, come, return, born, die, buy, arrive。

3、在时间或条件状语从句中，现在完成时代替将来完成时，表示将来某个时刻之前已经完成的动作。

4、现在完成时和一般过去时的区别

现在完成时：表示某一已完成的动作对现在造成的影响或结果，强调的是现在的情况，不能喝表示过去的时间状语连用。

一般过去时：只单纯表示过去的动作或状态，和现在不发生联系。它可以和表示过去的时间状语连用。
