Module 8 Unit 5 Meeting your ancestors 语法课

单元语法：复习现在完成进行时

学习目标：掌握现在完成进行时的正确用法。能够熟练区分和运用现在完成时和现在完成进行时的用法。

重点语法解说：

一、概述和构成

现在完成进行时表示从过去某时开始到现在为止一直进行的动作，这个动作可能仍在进行，也可能刚刚结束。

现在完成进行时由“助动词have/has （not）+been+ v-ing”构成，多用于持续性动词如live,learn,lie,stay,wait,stand,rest,study等，且常和all the time,this week, this month, all night, all the morning, recently以及“for+时间段”，“since+时间点”等时间状语连用。如：

The Chinese have been making paper for two thousand years.中国人造纸已有2000年历史了。

二、用法

（1）表示从过去某时开始一直延续到说话时还在继续进行的动作，有可能延续下去或可能刚刚结束。

I have been waiting you for about one hour.我等你大约一个小时了。(说话时"等"的动作刚结束) They have been living here for 10 years. 他们住在这里十年了。

（2）表示重复（只断断续续，而非一直不停）。

We’ve been discussing the matter several times this year.我们今年已数次讨论那件事。

I have been saying goodbye to some friends today.我今天同好几个朋友告了别。

现在完成进行时有时表示强烈的感情色彩（表扬或厌恶）。

Oh,you have come at last! I have been waiting for you for two long hours. 你总算来了，我等了你两个小时了。（表示强烈的不满）

三、现在完成时与现在完成进行时的比较

（1）现在完成时表示到现在为止已经完成；现在完成进行时往往表示仍将继续下去的动作。

They have built a ship.他们建了一艘船。（已完成）

They have been building a ship.他们一直在建一艘船。（在进行）

（2）当表示动作刚刚结束时，现在完成时强调动作的结果，现在完成进行时则强调动作在不久以前持续进行的情景。

Now we have cleaned the room; we can move the things in .现在房子打扫好了，我们可以往里搬东西了。（强调打扫完了的结果）

—You look so tired. What have you been doing?你看起来很累，你干什么了？

—I've been playing football.我踢足球了。（强调不久前踢球的情景）

（3）现在完成进行时比较生动，有时含有明显的感情色彩，而现在完成时往往只说- 1 -

What have you been doing? 你都干了些什么？（表示惊讶）

（4）表示状态、感觉和心理状态的动词如be, have, like, love, know, see, hear等，通常不能用现在完成进行时，而用现在完成时。

Have you seen her parents these days?这些天你看见她的父母了吗？
