During the Spring Festival I had a lot of delicious food.T: The Spring Festival is the most important Chinese traditional festival. During the festival, we usually have delicious food. But not all delicious food is health food. Please look at some photos of food. Can you tell what health food is and what junk food is?(Show some photos of food on the Powerpoint.)Step II Warming upFirst the teacher will show students how to describe the food shown in the photos, using the pattern “I think that . is junk/health food because .”(This pattern will be shown on the PowerPiont). Then ask students to tell what is health food and why these are health food while those are junk food. The teacher will give an example, talking about the photos with students.T: What do you think is junk food shown in the photos, Student 1?S1: I think that ice cream is junk food because it has a lot of fat and sugar.T: What is health food in your opinion, Student 2?S2: I think that vegetables are health food because they contain lots of vitamins.Then ask students to work in pairs talking about the photos and make sure students know what is junk food and what is health food.Every student should stand up and walk around the classroom to make a survey on five of his classmates of their eating habits. Try to find out how many meals they have every day, what their favourite food is and how much water they drink every day. Fill in the following form and decide whether what they eat is junk food or not.After students finish the form, show one or two on the projector and discuss with the whole class.Step III ReadingT: Eating habits are very important to our health.
