二．教学步骤
Step ⅠLead-in
This step is to lead the Ss to the topic of this unit ― A Healthy Life.
T: Recently, I read a report — Healthy China, 2005, which is about ten health issues concerning Chinese people the most in the year 2005. According to your understanding, what a healthy life is like? And can you guess what the ten issues are? Work in pairs and have a discussion.
After about 3 minutes.
T: OK, who would like to present your discussions?
S1: Let me try. In our opinion, a healthy life should include two aspects, physical health and
mental health. So a person who lacks either is not a healthy person. We think of several issues that may concern people most, they are: food security, medical service problems, AIDS and effects of environmental pollution on health.
T: Good points. Other issues concerning people most are: nutrition and health condition, medical emergency treatment, mental illness, false medical ads, medicine security and birth defects. If you are interested in any of these issues, you may search on the Internet for more information. Now turn to page 17, Warming Up. Here is a list of health issues that concern young people the most. Can you think of other issues that are also important? Work with your partners, and try to make the list longer.
A sample list:
AIDS and infections, parenting, relationships, food and nutrition, family issues, environmental health, domestic violence, air pollution, cancer, anxiety, birth control, dental health, divorce
Let the Ss write the list on the blackboard and have a discussion on the health issues listed.
T: Now, look at the issues on the blackboard and the issues listed in the textbook on page 17. Which issue do you think is the most important one? Why? Work in groups and have a discussion.
After discussion.
T: Which group would like to share your opinions with the class?
S1: We think that drug taking is particularly important. As we all know, drug taking does great harm to people’s health; it will gradually kill a person if he gets addicted to it. Buying drug costs a lot of money, so many drug takers sell out their fortune to afford the drug they need. And as a result, many families break up in this way. We also know that our government has to spend a lot of money on drug addicts’ treatment.
S2: We think parenting is the most important issue, because many issues arise as a result
of bad parenting or lack of care and love. If children grow up in happy and healthy families, they will form good habits and keep away from those bad habits such as using drugs and smoking.
S3: Our group takes smoking as the most important issue. The reasons are: smoking does great harm to people’s health, it causes damage to people’s lung and heart; smoking shortens people’s life-span; smoking not only does harm to people who smoke, but also affect the health of people around them, especially their family members.
Step Ⅱ Pre-reading
T: I agree with you all. All these issues are important and need to be concerned. I am wondering if any of you smoke. Anyone? ... OK. It seems nobody in our class smokes, that’s really good. I think you are all clear that smoking is harmful to health. But we know that some adolescents started smoking at very early years. Why do you think they smoke? Discuss in pairs.
2 minutes later.
T: OK. I’d like two pairs to present your opinions. Volunteer?
S4: I think some adolescents smoke because they are not well aware of the harm of smoking. Many adults around them smoke, so they may think it is cool to smoke. So I think it is parents’ duty to tell their kids about the harm of smoking before they get addicted to it.
