教学过程
一、热身（Warm-up）

See the flowers, see the flowers.
Playground, playground.
Let-s run, let's run.
Dining hall, dining hall.
Have lunch, have lunch.
Grass, grass.
Play football, play football.
Gym, gym.
Play basketball, play basketball.
活动方式：要求学生边说chant，边做动作。

1．Play a game: Bomb
活动方式：教师将school, library, playground, computer room, art room, music room. dining hall, grass, gym等单词卡片贴在黑板上，并将炸弹放在某个单词下，要求学生按照顺序快速说出这些单词。

当读到埋有炸弹的单词时，全班学生则要跳过不能发出声音，如果谁违规了，全班学生则对着他说“One, two, bomb”。

2．活动：学校今昔谈
活动方式：学生两人一组就学校的过去和现在展开对话，然后教师请几组学生到讲台前表演。

如：
Sl: Was there a computer in the classroom ten years ago? S2: No, there was a TV and some fans in the classroom.
Sl: Was there a library in our school five years ago?
S2: Yes, but it was small. Now there is big and bright.
Sl: I like the gym. I often play basketball and ping-pong in it.
S2: But there was no gym three years ago.
Sl: You’re right.
3．活动：听一听，猜一猜
活动方式：教师藏起一张运动项目的图片，让学生根据老师的描述，猜一猜是哪项运动项目，在活动过程中，学生可以随时猜，直到猜对为止，猜对的学生应给予奖励。

如教师藏起一张踢足球的图片： T: We often play it on the playground.
S: Morning exercises.
T: No. We play a ball.
S: Basketball.
T: No. We often use our feet and head.
S: Football.
T: Yes.
教师示范后，可让一名学生抽出一张运动类的图片，由该生描述它的特征，其他学生来猜。

三、新课呈现( Presentation)
1．教学单词cycling和词组go cycling
教师描述：This is a sport. It’s a popular sport. It’s a cheap way to get around. It’s a sport of traveling on a bicycle.学生猜测后，教师出示骑车的图片说：This sport is cycling.教师
板书：cycling，并采用“大小声”的方式操练单词。

教师边说：go cycling边模仿骑车的动作，骑到某个学生面前模拟将自行车交给这位学生，这位学生接过自行车后接着模仿骑车的动作说：go cycling，依次类推，全班接力说词组。

游戏结束，教师板书：go cycling，全班边模拟骑车的动作边读词组。

2．教学单词badminton
教师出示羽毛球拍问学生：Do you like badminton? Can you play badminton? 教师板书：badminton，play badminton，教师先分音节带读单词，然后引导全班齐读单词，再比一比谁最快记住这个单词。

教师边挥动羽毛球拍边说：play badminton，然后教师将球拍交给学生，让学生也边挥拍边说词组。

3．教学单词ice-skate
教师出示冰鞋的图片问：Can you ice-skate? 学生回答：Yes, I can. (No, I can’t.)教师板书：ice-skate，用升降调带读单词，全班拼读记忆单词ice-skate。

4．教学句子I didn’t like winter before. I thought it was too cold, a nd I couldn’t go cycling.
教师提问：Which season do you like best? Why? 学生回答后，教师说：I like winter. But I didn’t like winter before. I thought it was too cold, and I couldn’t go cycling.板书：But I didn’t like winter before. I thought it was too cold, and I couldn’t go cycling. 告诉学生：thought是think的过去式，
could是can的过去式。

最后让学生说说这两句话的意思，引导全班齐读句子。

5．教学句子：How about now? Now I love to ice-skate and play in the snow.
教师：I didn’t like winter before. How about now? Guess, please.学生发言后教师说：Now I like winter. I love to ice-skate and play in the snow.教师板书句子：How about now? Now I love to ice-skate and play in the snow.全班齐读句子。
