Step II Lead-in Present the sentences that contain the structure as “have/has been doing”

by showing the pictures.

Step III Explanation 一、结构形式

现在完成进行时是由“助动词have(has) + been+动词的现在分词”构成。

二、基本用法

1. 1, 叙述某一动作从过去开始一直继续到现在仍在继续之中或刚刚停止。经常与for, since, all morning/day/week用在一起。

1) You have been studying for four straight hours. Why don’t you take a break? 2) The telephone has been ringing for almost a minute. Why doesn’t someone answer it?

2.

叙述从过去某时开始一直继续到现在，但不再继续下去的事情。

－－带有浓厚的感情色彩，强调持续了“那么久”或做得“那么辛苦”

1)

Oh, you have come at last! I have been waiting for you for two long hours. (我等了你足足两个小时) 2) You are here! I have been looking for you long.（我找了你老半天）

3, 叙述“最近”一直从事的工作或活动。－－lately, recently ★What’s the matter? Your eyes are red and puffy. Have you been crying? (你是不是一直在哭？)

★

The weather has been changeable lately; I’ve been having a lot of colds. (最近天气变化无常, 我时常感冒。）

4, 叙述从过去某时到现在，或最近，一再重复的动作。

I have been knocking. I don’t think anybody’s in. (我一直在敲门。我想没人在里面。) I have been writing letters since breakfast. (我从早餐起就一直在写信)

三、注意事项

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

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, 但完成进行是常表示短暂性。

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.

（我的手很脏, 我在油汽车来着。）

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 have been phoning Jenny every night for the several months.

All these days he has been writing articles to our magazine. 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。
