现在完成时的用法
英语中的动词有多种分类法。
根据其有无含义，动词可分为实义动词和助动词；根据动词所表示的是动作还是状态，可以分为行为动词和状态动词；根据动词所表示的动作能否延缓，分为延续性动词和终止性动词。
可以表示持续的行为或状态的动词，叫做“延续性动词”，也叫“持续性动词”，如：be, keep, have, like, study, live, etc. 有的表示短暂、瞬间性的动词，叫做“终止性动词”，也可叫“短暂性动词”，或“瞬间性动词”，如die, join, leave, become, return, reach, etc. 终止性动词构成的现在完成时，不可以用表示一段时间的状语（如：since 和for引导的短语）来修饰，终止性动词构成的现在完成时，只表示动作发生的因果关系，不能表示动作的延续，因此不能用表示一段时间的状语来修饰。
如可以说：The Red Cross has already started for the earthquake-stricken area. 但不可说：The Red Cross has already started for the earthquake-stricken area for three days. 因为start是终止性动词, 它所表示的动作短促, 当红十字会出发时，start这个动作便结束了, 不可能延续两天。
在十多年的教学生涯中，发现学生对于如何解决这对矛盾不知所措，下面我来归纳一下解决这对矛盾的四种方法。
1. 用ago时间状语短语来代替since或for引导的时间状语： eg. Mr. Richard has returned from America for two years. (wrong) Mr. Richard has returned from America since two years ago. (wrong) 应改为: He returned from America two years ago. 2．用It is… since…复合句代替简单句eg. It has been/is two years since Mr. Richard returned from America. 注意：以上两种办法适用于所有终止性动词。

现在完成时的四种用法
现在完成时的四种用法现在完成时是英语中一个很重要的时态，也是很容易弄错的一个时态。
归纳起来，现在完成时共有四种主要用法，现分别解说如下：一、现在完成时表示影响该用法的现在完成时表示一个过去发生的动作在过去已经完成，并且这个过去发生并完成的动作对现在有影响或结果，同时说话者强调的或感兴趣的就是这个影响或结果，如汉语说“他已离开这个城市了”，其中的“离开”肯定发生了，它对现在的影响或结果就是“他现在已不在这个城市了”；又如汉语说“有人把窗户打破了”，显然“打破窗户”这一动作发生在过去，并且在过去已经完成了，但说话人强调的重点是打破窗户对现在的影响——窗户现在仍是破的。
如：He has left the city. 他已离开这个城市。
(结果：他不在这个城市。
)Someone has broken the window. 有人把窗户打破了。
(结果：窗户仍破着。
)I have lost my pen. 我把钢笔丢了。
(结果：我现在无钢笔用。
)He has finished his work. 他把工作做完了。
（结果：他现在可以做其他的事了。
）二、现在完成时表示持续该用法的现在完成时表示一个过去发生的动作或开始的状语在过去并未完成或结束，而是一直持续到现在，并且有可能继续下去(也可能到此结束)，如汉语说“他在我们学校教书已有30年了”，显然“他在我们学校教书”是从30年前开始，并且一直教到现在，已经持续了30年；又如汉语说“自上个星期以来他一直很忙”，显然“忙”是从上个星期开始的，并且这一“忙”就一直忙到现在。
如：He has taught in our school for 30 years. 他在我们学校教书已有30年了。
He has been busy since last week. 自上个星期以来他一直很忙。
