Step II

Lead-in Ask the Ss to point out the sentences that contain the structure as “We have been excavating here for many years” in the text. Step III Explanation 现在完成进行时

1. 构成形式:

has\have been doing 2. 用法

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。

You have been studying for four straight hours.

1

Why don’t you take a break?

The telephone has been ringing for almost a minute. Why doesn’t someone answer it?

2) 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? 3) 表示重复动作。有时现在完成进行时所表示的动作并不是在一直不停地进行, 而是

在断断续续地重复。

I have been knocking. I don’t think anybody’s in.

我一直在敲门, 我想没人在里面。

You’ve been saying you can succeed for five years.

5 年来你一直在说你能成功。

I have been writing letters since breakfast.

我从早餐起就一直在写信。

4) 表示“刚才、近来”发生的动作, 一般不再继续。此时一般通过上下文的语境进行判断。

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

我的手很脏, 我一直在漆门。

What have you been eating to get as fat as this?

你都吃什么啦, 怎么这么胖？

5) 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”。

I have been wanting to meet you for a long time.

和你见面是我盼望已久的事了。

Too much has been happening today.

今天真是一个多事的日子。

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。

You are here! I have been looking for you long. 我找了你老半天。

现在完成进行时与现在完成时的区别

现在完成时表示结果, 其动作发生在过去，但对现在有影响; 而且现在完成时也可表示动作的持续。而现在完成时表示比较长久的动作和状态, 而现在完成进行时表示较短暂的动作和状态, 而且强调持续性或未暂停性。

I haven’t been working very well recently.
