2. What is your hobby?

2．让学生自述自己做某一件事的情况。

如：

Saturday. 等。

3．通过打电话对本班的同学作一个采访，询问他/ 她正在做什么？做了多久了？是否打算继续做下去？并请同学们汇报调查结果
完成任务所需要的语言结构：

4．同学们，为了丰富你们的课余生活，学校准备组织课外活动小组。

在组织活动小组之前，学校要对你们的爱好进行调查，你们有些什么爱好呢？这些爱好从什么时候开始的？到现在持续了多久？
请同学们通过这个练习学会“since”和“for”在表示时间时的用法。

2．I have been collecting kites for seven years.
3．He has been watching English movies since 1998.

Unit 6 How long have you been collecting shells? 第四课时
一．疑难解析
I．如何表示“从过去开始一直持续到现在，有可能还要持续下去的动作”。

如：到现在为止她滑冰已经有四个小时了。

又如：我从十岁起就一直在集邮。

我们采用如下的方法来表示“从过去开始一直持续到现在，还要持续下去的动作”：
主语+ have / has been + 现在分词，如：
1．She has been skating for four hours.
到现在为止她滑冰已经有四个小时了。

2．I have been collecting stamps since I was ten years old.
我从十岁起就一直在集邮。

在这两个句子中，have和has是助动词，因此把助动词题签，就构成了一般疑问句，在have或has后面加not，就构成了否定形式，have not和has not可以分别缩写成haven’t和hasn’t 。

如：
1．Have you been doing your homework since this morning?
从今天早晨起你就一直在写作业吧？
（表明写作业这个动作从今天早晨就开始了，一直持续到现在，还要持续下去。

）
2．I haven’t been seeing films for a long time.
我有很长时间没有看电影了。

（表明没有看电影这个动作从过去一直持续到现在，还要继续持续下去。

）
II．区分“主语+ have / has been + 现在分词”和“主语+ 动词过去式”这两个句式的不同点及熟练掌握这两个句式的用法。

1．“主语+ have / has been + 现在分词”表示动作从过去开始一直持续到现在，并且还要继续持续下去。

如：
He is a pianist. He has been playing the piano for about twenty years.
他是一个钢琴家。

他弹钢琴大约有二十年了。

弹钢琴这个动作从二十年前就开始了，一直持续到现在，由于他是个钢琴家，那么弹钢琴这个动作还要继续持续下去。

这里强调持续，而不是二十年间他一刻不停地在弹琴。

又如：
I have been collecting snow globes for seven years.
我收集里面有雪花的玻璃装饰品有七年了。

我有这个爱好，七年间我一直在收集这样的装饰品，但是不等于七年间我别的什么也没干。

2．“主语+ 动词的过去式”表式过去某个时间已经发生了动作，有比较明确的表示过去的时间状语。

如：
I did my homework last night.
我昨天晚上做的作业。

表明“做作业”这个动作发生在昨天晚上，动作没有持续性。

二．写作指导
大家在学完这个单元以后要完成两个写作任务，即写一个招聘广告和一封应聘信。

招聘广告可以模仿49页上的第3题来写，应聘信可参考第48页上的3a来写。

下面请看示例：
学校歌咏队要参加一个歌咏比赛，故而要招聘新成员，请你帮歌咏队写一个招聘广告。

应聘信
