Step I. Lead-in

Look at the pictures below and make sentences according to the time given. The woman has been working for four hours. They have been playing games in the school for almost an hour. The telephone has been ringing for almost a minute.

You are here! I have been looking for you everywhere. Step II. Explanation 现在完成进行时

1.结构：

have / has been+动词的现在分词

2. 现在完成进行时的用法

1）强调动作的持续性。

表示从过去某时开始, 一直持续到现在的动作，可能刚刚停止，也可能还在继续进行。

I have been learning English since three years ago.

We have been waiting for you for half an hour. 2)表重复。叙述从过去某时到现在或最近一直重复的动作。如：

最近天气变化无常, 我时常感冒。

The weather has been changeable lately; I’ve been having a lot of colds.

3)有感情色彩。如：

今天真是一个多事之日。

Too much has been happening today. 3.现在完成进行时和现在完成时的比较

A.未完结性

I’ve cleaned the windows.

我把窗户擦干净了。

I’ve been cleaning the windows.

我擦窗户来着。(可能窗户尚未擦完) B.短暂性

- 1 -

现在完成时与现在完成进行时都可以表示延续至今的状态, 但完成进行时常表示短暂性。

a. They have lived in New York.

b. They have been living in New York.

句a具有长期性, 而句b具有短暂性。

C.刚完结性

与现在完成时相比, 现在完成进行时有时可以表示刚刚完结的动作。有时它是现在事件的直接原因, 或者是得出结论的证据。如:

My hands are dirty. I’ve been painting the car.

Your eyes are red and puffy. Have you

been crying?

你的眼睛又红又肿, 你是不是哭来着？

D.连续性或重复性

现在完成进行时常常用于表示延续至今的连续性或重复性动作。如：

Jim has been phoning Jenny every night for the several month.

All these days he has been writing articles to our magazine. 4.结论:

现在完成进行时主要用于表示

A.过去开始而且现在仍在进行的动作;

B.过去开始, 现在刚刚停止的动作;

C.现在看到其直接结果的动作。

现在完成时主要用于表示已经完成的动作及其与现在的关系。
