Lead inHello, everyone! Today we are going to talk about an interesting topic-Health Eating. Before our beginning, please write down what you each think about making a healthy meal, whether you eat a healthy diet, and whether you know that the food you eat helps you grow in different ways. As youre ready, compare your idea with your partner. And then, well invite some pairs of you to give us your ideas.Classify food according to their functions and fill in the form.Foods to give energyFoods to grow bones and muscle (body-building foods)Foods that give fiber for digestion and health(protective food)Fast energy foodSlow energy foodrice noodlesbreadbutter.meateggsmilk.all vegetablesall fruit.Step 2. DiscussionAsk Ss to work the following questions out in groups and let them become familiar with the contents of each one. Questions: 1. Why do you think the food is divided into different groups?2. How does this information help you make a healthy meal?Step 3. AnalysingNow, please design a meal which they enjoy. And then analyse your meal according to the categories of food set out in the textbook.1. Is their meal balanced?2. Does it include food from each of the three categories? What (if anything) is missing?Step 4. To examine the answers.The first three questions are all persons. But the forth question is not. (What will happen to you if you dont eat a balanced diet?)Suggested answers: if you eat too much energy-giving foods you will become fat and suffer from high blood pressure; if you eat too much body-building food you will grow taller and stronger but not necessarily healthier; if you eat too much protective foods for every meal you may lack energy. However without protective food(over a long period of time) you can get serious illnesses like scurvy(lack of vitamin C) or rickets(lack of vitamin D); if you dont eat enough food of any of the three kinds you may get anorexia(too thin).Step 5. Homework: Write down more you know about diet.Period two ReadingTeaching aims:1. Enable Ss to become more aware of the difficulties associated with prepared foods. 2. Help Ss know the harms of unbalanced diets.Teaching procedures:Step 1. Pre-reading1.

Thinking1) What do you think should go into a good meal?2) Imagine you and your partner are going to invite some friends for dinner. What special food of your place would you offer them? Plan a menu.Answers: 1) A good meal should contain some food from each of the three categories above. 2) Sample dialogue:S1: Now our favourite dishes in my hometown involve noodles. What abut you?S2: Well, I like noodles too, so lets use that for the energy-giving part of our dinner. S1: What do you like to eat with noodles?S2: My favourite sauces are spicy ones. So lets suggest noodles with spicy tofu. Thats very healthy and contains some of the body-building food too. Now we just need to include the protective food.S1: Yes, youre right. Now what about vegetables? Theyre protective food and I think beans are nice with some sour and spicy sliced potato.S2: Sounds fun to me. Lets write it down3.
