2、教授歌谣“Everyone, Everyone, Reach up High” 使学生能跟着节拍边做动作边说歌词。

3、通过本课教学，使学生了解健康的生活方式应加强体育锻炼。

教学重点：

掌握本课四会单词: minutes, hours, exercise

教学难点：

如何在实际中灵活运用 How much/How many/How often是难点。

教具、学具：

一个带有分针的钟表、录音机、课文录音带。

教学过程：

一、 Class Opening and Review：

1、Play “What Time Is It” to review how to say times.

　 T: Hello! Now look, what is it?

   S：Watch.

   T：It is a clock. What time is it now?

   S:  It is_______.

二、Key Concepts：

1、Introduce：

　　(1) Demonstrate “minute, hour” with a big clock .

　　(教师用手拨动时针，正好经过一个小时)

　　T: How many minutes does it past?

　　S: …..

　　T: One hour. Hour, say it.

　　S: Hour.

　　T: How many minutes make an hour?

　　  Minute, say it and guess what it means here.

　　S: Minute.

　　(教师可以用钟来提示学生 minute 是什么意思。同时教师还可以扩展秒，年，天。)

T: Yes, sixty minutes make an hour. Say it.

     S: Sixty minutes make an hour.

     T: How many seconds make a minute?

     S: …….

　　 T: Now look, what time is it now? It is time for exercise.

What does it mean? Guess.

(2) Play“Simon Says” to review actions and phrases such as：ride a bike, walk to school, run, jump, play ping-pong, play soccer, play basketball 等。Some volunteers. Ask each volunteer (in a whisper) to perform an action. Ask the class to guess what he or she is doing . Then ask all the volunteers to perform their actions at the same time and lead a dialogue：　　

T: Look! They are exercising! (Point to each volunteer) Riding a bike is exercise.

　　Playing ping-pong is exercise.

　　Walking is exercise.

　　What else is exercise? (Point to the next volunteer.) __ing is ...

　　S: …exercise.

　　T: Right! (Point to the final volunteer.) And __ing is …

　　S : …exercise.

　　T: Very good!

　　(3) 游戏

　　规则 ： 两个同学上前面来，一个同学面向大家，另一个同学用事先准备好的单词大卡片对着同学，让同学们做动作，前一位同学猜 __ing is exercise . (安排这个环节主要是为了巩固刚刚学过的句型和单词exercise.为下面的学习做准备。)

　　2、Use the Student Book and Audiotape:

　　(1)《教科书》第一部分 T：Exercise helps make your body healthy and strong. 出示问题：What is exercise? How much exercise do you need? 学生边看书边听课文录音，同桌讨论后回答。回答第一题引出动名词短语作主语这一知识点，板书：Riding a bike/Walking to school/Running/Playing ping-pong is exercise. 回答第二题时引出How much 与 How many 的区别， 并利用钟表演示使学生能回答: How many minutes are there in an hour? / How many minutes make an hour?

(2) Ask a volunteer.

T: How do you go to school?

　 V: ride a bike.

　 T: Is riding a bike exercise? How often do you exercise a day？　　V: …… ……

　 T: How many minutes do you exercise a day?

　 V :…….

　学生分组进行对话练习，然后找同学进行检查。

（给学生实践的机会，让学生联系自己的生活实际进行英语学习，加强学生对语言的驾驭能力。）

　《教科书》第二部分

出示问题：How many minutes dose Danny exercise? How often dose Danny exercise? How many minutes dose Danny walk to school? 听课文录音小组讨论后得出结论：Danny needs to get more exercise. 采取多种方式操练：同桌对话、小记者采访的形式询问同学们的锻炼情况，在活动中复习并巩固句式的运用，深刻领悟锻炼的重要性。

　　3、Practice:

　　(1) T： Now, let’s do some exercise together. Ok?

Read the passage in Part 3 Read and write. Then finish the table.

Students say the sentences according to the table: I exercise 2 hours

in a week …

(2)Let’s chant“Everyone, Everyone, Reach up High”

三、Class Closing:

Homework:(1) 画出一些动作或尽量用动作表演出来来练说:___ing is exercise.
