教学过程：
Pre-task preparations
1、教师与学生问答，复习日常用语，为本课时新句型的学习做铺垫。
T: How do you feel today?
S1: I’m fine.
S2: I’m just so so.
S3: I’m happy today. It’s my birthday.
2、播放歌曲An apple a day keeps the doctor away.的动画，让学生欣赏并跟唱。
While-task procedures
1、出示listen and enjoy的图片，与学生问答。
T: Look at these pictures. Is the boy feeling well?
S1: No, he isn’t.
T: How’s he?
S1: He is sick.
T: What does he do?
S1: He goes to see the doctor.
接着，学生看图听儿歌，回答问题，与此同时，教师出示look and learn的单词卡片，教授生词。
T: How’s he?
S1: He has a toothache.
S2: He has a fever.
S3: He has a cold.
S4: He has a headache.
T: Have a toothache. Ache means pain. Toothache. T-o-o-t-h-a-c-h-e, toothache.
Ss: Toothache. T-o-o-t-h-a-c-h-e, toothache.
然后教师用同样的方法教授短语have a fever，have a cold，have a headache。最后，教师将这些图片拿在手中，任意选出一张，让学生快速说出短语，以巩固记忆。
2、学生以小组形式讨论listen and enjoy 中男孩牙疼的原因。然后，学生说说讨论的结果。教师可先与一名学生对话，作为示范。
T: Why does the boy have a toothache?
S1: He doesn’t brush his teeth.
T: How many times do you brush your teeth every day?
S1: I brush my teeth twice a day.
T: Oh. He should brush his teeth twice a day.
S2: He eats too much candy.
T: Yes, he shouldn’t eat too much candy.
S3: He eats before bedtime.
T: So he shouldn’t eat before bedtime. I think he must go to see the dentist.
...
3、引导学生用...should/shouldn’t ...句型给男孩提出建议，并将核心句型板书在黑板上。
T: The boy has a toothache, because he doesn’t brush his teeth twice a day. We can say “Please brush your teeth twice a day.”We can also say”You should brush your teeth twice a day.”
Ss: You should brush your teeth twice a day.
T: Don’t eat too much candy. We can also say “you shouldn’t eat too much candy.”
Ss: You shouldn’t eat too much candy.
请学生用...should/shouldn’t ...句型表述黑板上的其他祈使句。
4、学生两人一组，根据Ask and answer的图片和句型提示结对问答。操练核心句型和词汇。
Post-task activities
播放listen and say的录音，学生听录音并跟读儿歌，再一次复习巩固已学词组和句型。然后，学生四人一组，思考have a fever和have a cough时应该注意些什么。
