At the beginning of the class, the teacher can lead in the topic of the unit by showing students some pictures about foods and talking about them.Warming Up is to tell students how different kinds of food are grouped. This is important as it enables us to talk about the value of particular foods to our health. We want students to appreciate what a balanced diet is. Too much fatty food will mean they store extra energy in their bodies. Too much body-building food may cause problems for digestion and lead to illness unless enough fibre foods are eaten to aid digestion. The teacher can have a free talk with students, let them work in pairs to read through the chart and discuss the questions.Pre-reading contains two more general questions about food for discussion. Students can be encouraged to discuss these questions in pairs. Then they are asked to look at the title of the reading passage and the pictures to predict what the passage is about. This part is very useful for the next part Reading.The reading passage Come and Eat Here(1)introduces students to two unbalanced diets through the restaurants of Wang Peng and Yong Hui. Food at Wang Pengs restaurant contains too much fat while Yong Huis restaurant offers little energy-giving food. The person who often eats at Wang Pengs restaurant will become too fat. That can lead to illnesses such as a heart attack or high blood pressure. The person who often eats at Yong Huis restaurant will become too thin and suffer illnesses such as anorexia or malnutrition. It is important for students to know about the two extremes and avoid them. The teacher can encourage students to skim for the general idea and scan for further understanding. Because this passage introduces a lot of new words, which are only used for food, in order not to let students feel much difficult, the teacher should deal with any language problems while they are reading. After reading, students are required to do the exercises in Comprehending to see how much they have understood the reading passage. The teacher can let them work in pairs or in groups to find the answers cooperatively, and then check their answers with the whole class.To consolidate the contents of the reading passage, students should be required to read the passage again and then retell it. In order to arouse their interest, the teacher can hold a competition. The teacher also needs to make a summary on the passage including the general idea, writing characteristics, and so on to let students understand the passage further at the end of the class.教学重点1.
