第二課時
一、任務(wù)示范及講解
1．通過打電話的方式了解同學(xué)們有什么愛好（如：打籃球、彈鋼琴、學(xué)英語等）；這個愛好持續(xù)了多長時間？在過去某一個時間里是否做過這件事（如：昨天、前天、上個星期等等）；做了多長時間？
Name Hobby How long (for) Time (past) How long (for)
完成任務(wù)所需要的語言結(jié)構(gòu)：
1）. What’s your name?
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.
下面請聽老師示范：
Name Hobby How long (for) Time (past) How long (for)
Wang Gang play football for five years yesterday one hour
Li Hong dancing for seven years last Sunday two hours
Zhao Ming swimming for four years last week ten hours
2．讓學(xué)生自述自己做某一件事的情況。如：
I have been studying dancing for about five years. I danced for about two hours last Saturday. 等。
3．通過打電話對本班的同學(xué)作一個采訪，詢問他 / 她正在做什么？做了多久了？是否打算繼續(xù)做下去？并請同學(xué)們匯報調(diào)查結(jié)果
完成任務(wù)所需要的語言結(jié)構(gòu)：
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?
下面請聽老師示范：
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． 同學(xué)們，為了豐富你們的課余生活，學(xué)校準(zhǔn)備組織課外活動小組。在組織活動小組之前，學(xué)校要對你們的愛好進(jìn)行調(diào)查，你們有些什么愛好呢？這些愛好從什么時候開始的？到現(xiàn)在持續(xù)了多久？
請同學(xué)們通過這個練習(xí)學(xué)會“since”和“for”在表示時間時的用法。請看下面的例句：
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.
通過以上例句我們可以看出for后面接的是一個時間段：eight hours和 seven years，而since后面接的是具體的時間點(diǎn)：1998 （1998年）、I was seven years old（我7歲）。
首先聽老師的示范，……，下面請同學(xué)們自己完成表格。

完成任務(wù)所需要的語言結(jié)構(gòu)：
