unit 6 How long have you been collecting shells?(新目標版八年級英語下冊教案教學設計)

第二課時

一、任務示範及講解

1．透過打電話的方式瞭解同學們有什麼愛好（如：打籃球、彈鋼琴、學英語等）；這個愛好持續了多長時間？在過去某一個時間裏是否做過這件事（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)

完成任務所需要的語言結構：

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.

下面請聽老師示範：

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．透過打電話對本班的同學作一個採訪，詢問他 / 她正在做什麼？做了多久了？是否打算繼續做下去？並請同學們彙報調查結果

完成任務所需要的語言結構：

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?

下面請聽老師示範：

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． 同學們，爲了豐富你們的課餘生活，學校準備組織課外活動小組。在組織活動小組之前，學校要對你們的愛好進行調查，你們有些什麼愛好呢？這些愛好從什麼時候開始的？到現在持續了多久？

請同學們透過這個練習學會“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.

透過以上例句我們可以看出for後面接的是一個時間段：eight hours和 seven years，而since後面接的是具體的時間點：1998 （1998年）、I was seven years old（我7歲）。

首先聽老師的示範，……，下面請同學們自己完成表格。

完成任務所需要的語言結構：
