教学步骤：

Step 1 Greetings

Greet the whole class as usual. Step 2 free talking

Show students a picture in which a beautiful girl is waiting for someone by the sea. T: Is it a beautiful picture? Ss: Yes, it is very beautiful. T: Who do you know she is waiting for? Ss: ……

T: As far as I know, she has been waiting for him (her husband) for ages. Do you believe it? Ss: ……. (On the blackboard, write down “As far as I know, she has been waiting for him (her husband) for ages.”) T: Believe it or not, it is up to you. But now let’s just have a look at the sentence on the screen. What kind of TENSE is it in the sentence? Ss: It is the present perfect. …

T: Not exactly. It is another tense, which is called The Present Perfect Continuous. Now let’s get a close look at the tense. Step 3 Lead-in Here are some scenes where we can use the tense The Present Perfect Continuous to express them. Picture1 My younger brother (access)the net for a long time. (has been accessing ) Picture2 The baby (sleep)for 1 hour(now it is still sleeping). (has been sleeping ) Picture3 They basketball all the day(from morning to 5:00pm). (have been playing) Picture4 The boy a book for almost 4 hours(he is still reading now.).(has been reading) Picture5 He with his girlfriend for half an hour(They are talking now).(has been talking) All the sentences include the tense: The Present Perfect Continuous

Step 4 The Present Perfect Continuous

Task1现在完成进行时: 概念及结构

概念：现在完成时表示一个由过去某一时间开始并一直延续到现在的动作，这个动作在可能刚刚结束，也可能还要进行下去。例如：(Ask students to translate the following two Chinese sentences into English) 我从1999年起就一直在教英语。

I have been teaching English since 1995. 我们已经在灵山中学读了2年书了。 We have been studying in Lingshan senior school for 2 years. 结构: have/has been doing

Task 2 describe the following pictures in pairs Picture1 (A pig is running) I don't know why the pig in the whole morning.

Picture2 (Some people and students are playing games) They games in the school the whole morning. (from 11:00 to now)

Picture3 (A girl is waiting her favorite football star) Oh, you have come at last! I you for two long hours (from 13:00 to 15:00).(我等了你足足两个小时)

Picture4 (A boy baby is crying) He (他一直在哭) , because he cann’t get what he wanted. Task3 the characteristics of the Present Perfect Continuous Tense (现在完成进行时的特征) 1)强调时间的持续性。如： 电话响了差不多一分钟, 为什么没人接? The telephone has been ringing for almost a minute. Why doesn’t someone answer it?

2) 表重复。叙述从过去某时到现在或最近已在重复的动作。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. Task 4 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。如: 我的手很脏, 我在油汽车来着。

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

你的眼睛又红又肿, 你是不是哭来着？

Your eyes are red and puffy. Have you been crying? 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 month. 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跟 现在的 关系。 Attention: for+一段时间，不一定都用现在完成时。如果说的是过去的一件事情，则用一般过去时。

例如：

My father________a worker for 10 years. He _________ once in the army for 3 years. ( be) 父亲做工人10年了，他曾经在部队里呆过3年。 结论 : 1. 现在完成时强调过去的动作对现在造成的影响。 2. 过去的一件事情持续多长时间或发生多少次，用一般过去时。
