教具、学具：
一个带有分针的钟表、录音机、课文录音带。

一、 Class Opening and Review：
1、Play“ What Time Is It” to review how to say times.
2、Play“Simon Says” to review actions and phrases such as：ride a bike, walk, run, jump,play ping-pong等。
二、Key Concepts：1、Introduce：
(1) Demonstrate“minute, hour”with a big clock.
(2) Demonstrate“exercise” with five volunteers. Ask each volunteer (in a whisper ) to perform an action(use the actions recommended for “Simon Says” above.) 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 ...
C: …exercise.
T: Right! (Point to the final volunteer.) And __ing is …
C: …exercise.
T: Very good!
2、Use the Student Book and Audiotape:
(1)《教科书》第一局部 T：Exercise helps make your body healthy and strong.出示问题：What is exercise? How much exercise do you need? 同学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， 并利用钟扮演示使同学能回答: How many minutes are there in an hour?/How many minutes make an hour?
(2)《教科书》第二局部 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: Teach “Everyone, Everyone, Reach up High” in Number 3 of the student book.
