Unit2 Healthy eatingPeriod one Warming upTeaching aim:To appreciate what a balanced diet is.Teaching procedures:Step 1. 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 groups2. How does this information help you make a healthy mealStep 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 balanced2. Does it include food from each of the three categories What (if anything) is missingStep 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.
