1．通过打电话的方式了解同学们有什么爱好（如：打篮球、弹钢琴、学英语等）；这个爱好持续了多长时间？在过去某一个时间里是否做过这件事（如：昨天、前天、上个星期等等）；做了多长时间？

完成任务所需要的语言结构：

2) What is your hobby?
3) How long have you been playing basketball?
4) I have been playing basketball for about ten years.
5) How long did you play it yesterday?
6) I played it for about two hours.
下面请听老师示范：

2．让学生自述自己做某一件事的情况。如：
I have been studying dancing for about five years. I danced for about two hours last 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：
1) What are you doing?
2) When did you do it?
3) How long have you been doing it?
4) How long did you do it?
下面请听老师示范：
A: What are you doing?
B: We are watching a new movie.
A: How long have you been watching it?
B: We have been watching it for about ten minutes.
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。请看下面的例句：
1) The skating marathon has been going for eight hours.
2) I have been collecting kites for seven years.
3) He has been watching English movies since 1998.
4) I have been listening to music videos since I was seven years old.
通过以上例句我们可以看出for后面接的是一个时间段：eight hours和 seven years，而since后面接的是具体的时间点：1998 （1998年）、I was seven years old（我7岁）。
首先听老师的示范，……，下面请同学们自己完成表格。
