Step I Warming up
Review the words of foods by showing their pictures. First, ask students to list the foods they like best. Then tick off 3 of them they eat most often. Second, show the three groups of foods and see which group their foods belong to. Third, ask students to tell us in what ways their foods help them grow.
T: There are so many delicious foods. What’s your favorite?
S1: I love eating meat, sugar and bread. My mother is sure to cook meat for me every day. I enjoy all kinds of meat, such as roast pork, beef, mutton kebabs and fried chicken. I have been used to eating sweets or bread while watching TV.
T: So what have happened to you?
S1: I am getting fatter and fatter. They all call me a big couch potato. But I can’t resist the attraction of them.
S2: I often eat vegetables, fruits and noodles. In order to keep slim, I only have a bowl of noodles each time. My parents are worried about my health. But I think it is worth the loss.
T: You have enough fiber. Would you mind me asking you a question? Do you often get tired while you are at school?
S2: Very often. I feel I ought to get more energy.
T: Now do you think we should eat each kind of food?
S: Yes. We need every kind of food to give us energy, fiber, protein and minerals so as to grow healthily.
T: So what does healthy eating mean?
S: Healthy eating means a balanced diet.
T: Right. Eating properly and maintaining a healthy weight are extremely important for us students, because we are growing and going through major changes to our body, mind and emotions. So remember the three groups of food: energy-giving, body-building and protective foods.

Step II  Pre-reading
Get the students to discuss the questions with their partners in this part. Then ask them to report their work. This part will help the students understand the text.
T: Please look at the slide show and discuss the questions with your partners. Then I’ll ask you to report your work. Are you clear?
Which food contains more...? Examples of foods Answer
sugar chocolate or grapes
cakes or bananas chocolate
fat cream or rice
chocolate or chicken cream
fiber peas or nuts
pork or cabbage nuts
protein potato crisps or ham
eggs or cream ham eggs

S: For the fattest food, the correct order I think is ice-cream, eggs, chicken, rice and peaches.
T: Do you agree with her / him?
S: Yes, I do.

Step III  Reading
Get the Ss to comprehend the passage quickly and accurately and meanwhile help the Ss to form a good habit of reading. Teacher gives the Ss a couple of minutes to look through the whole passage. Tell the Ss to read the text silently and then ask for the main idea of the text on the slide show with their partners. Teacher encourages the Ss to express their ideas.
T: What health problem do you know are connected with eating?
S: Too fat, too thin, anorexia, heart attack and high blood pressure.
T: In the USA there are a lot of people who are fat or getting fat. They have health problems as a result of not eating properly. So the whole society is concerned about what people can do to help them lose weight and keep fit. In order to satisfy people’s need and especially to continue to share the market, the famous fast food chain McDonald’s restaurants develop a new kind of potato crisps and put a lot of cabbages into their hamburgers. Here we’re going to learn a story about a competition between two restaurants. Let’s see what’s the result.
Fast reading
In this part the teacher should ask the students to read the passage quickly for the first time to find out the main idea of the text. Then ask them to read the text again carefully to obtain some details. Before reading show the tasks on the screen and let the students read the sentences first. This task can help them have a good understanding about the text.
1. The two restaurants supplied the healthy diet.
2. The reason why Yong Hui’s restaurant was so popular with customers.
3. Wang Pengwei found out why he had lost his customers and decided to win them back.
T: At first I’d like you to read the text quickly to get the general idea of the text. Pay attention to the sentences which contain modal verbs.
(2 minutes later)
T: Stop here. Which one do you prefer?
Ss: We’d prefer the third sentence.
T: Why do you prefer it?
S1: As far as I can see, it is the third sentence. The first one is not true because they didn’t supply the healthy diet. And the second sentence is a piece of information about Yong Hui’s restaurant we can get from the text.
T: Do you agree with her/ him?
S2: Yes. That’s exactly my opinion. In this story Wang Pengwei is one of the leading characters. This part only tells us how the competition began and what Wang Pengwei would do next.
T: Well done.
Careful reading
T: Now, it’s the time for us to read the text carefully and decide which sentences are true. Then correct the false ones. First read the sentences.
1. Usually Wang Pengwei’s restaurant was full of people.
2. He provided a balanced diet in his menu.
3. Yong Hui served a balanced diet.
4. Yong Hui could make people thin in two weeks by giving them a good diet.
5. Wang Pengwei’s customers often became fat after eating in his restaurant.
6. Yong Hui’s menu gave them energy foods.
7. Wang Pengwei’s menu gave them foods containing fiber.
8. Wang Pengwei admired Yong Hui’s restaurant when he saw the menu.
9. Wang Pengwei decided to copy Yong Hui’s menu.
Give the students 7 minutes to read the text and to think over or discuss the questions. The teacher should walk around the classroom to help those students who need help.
Ss: a. Sentence 1 is true. We can see it from the sentence “His restaurant ought to be full of people.”
b. It’s false. He didn’t provide a balanced diet in his menu, because his menu made people fat.
c. It’s false. Yong Hui didn’t serve a balanced diet either, because her menu only served people with protective foods.
d. It’s false. I don’t think Yong Hui gave them a good diet. She could make them not only thin but also unhealthy by only giving them raw vegetables, fruits and water.
e. Sentence 5 is also true. Because people wouldn’t go to Wang Pengwei’s restaurant and his menu is full of fat and sugar.
f. It’s false. Yong Hui gave them protective foods.
g. It’s false. Wang Pengwei’s  menu gave them foods containing much fat and energy.
h. It’s false. Wang Pengwei didn’t admire her when he saw the menu. He didn’t believe what she said and planned to stop her from telling lies.
i. It’s false. He decided to improve his menu to compete against her.

Step IV Comprehending
By now, the students have had a further understanding about the text. Let the students read the text again and find out the differences between the two restaurants.
T: Now please read the passage again and fill in the chart on the screen together with your partners.
 advantages disadvantages
Wang Pengwei’s restaurant Not giving enough foods containing fiber Providing plenty of energy foods
Yong Hui’s restaurant Not giving enough energy foods Providing plenty of fiber foods.

Next discover whether the students have understood the ideas in the reading passage.
T: Until now we have known what’s wrong with both restaurants. What does it matter if you only eat at one of the restaurants?
S1: If we often eat at Wang Pengwei’s restaurant we’ll become too fat which can lead to illnesses  such as heart attack or high blood pressure.
S2: If we often eat at Yong Hui’s restaurant, we’ll become too thin and suffer illnesses such as anorexia or malnutrition.
T: That sounds dangerous. How can they make a balanced diet?
S3: I think both restaurants should supply all kinds of foods so that every customer can eat a little of each kind at the same time. As a result, we don’t worry about what they will lack of.
S4: I don’t agree with you. It’s not realistic. In my opinion, Yong only receives fat people and help them lose weight; Wang only receives slim people and help them to get enough energy.
S5: I’m afraid I can’t agree with you all. I hope the two restaurants will join together as a new one which has all the advantages and avoids the disadvantages.
T: You all have a point there. But what will they do? We will see it next class. Facing the serious competition, Wang wasn’t lost in sadness and he didn’t quarrel with his competitor either. He went to the library to learn more about healthy eating and made his menu better than Yong Hui’s menu. Do you think we should follow his example?
S6: That’s correct. Exactly.
T: Good. What’s your opinion of Yong Hui? Is what Yong Hui did right? Why?
S7: I don’t think she is right. Yong Hui didn’t give us a good diet. She could make us not only thin but unhealthy if we often eat there. She made an unhealthy menu to agree with the fashion and her meal was too expensive. She cheated the customers and they didn’t know they would become unhealthy if they often ate there. So I wouldn’t go there to have a meal.
T: Now let’s deal with some language points. Turn to Page 10. Let’s look at the sentences:
Wang Pengwei sat in his empty restaurant feeling very frustrated.
This sentence means that the second action “feeling very frustrated” happened together with the main action “sat”. Pay attention to the form (v-ing ) of the second action.
Nothing could have been better.
This sentence tells us that everything has worked out the way you would like. It is a sentence that we can use it in any situation.
He couldn’t have Yong Hui getting away with telling people lies!
This sentence means that he will punish Yong Hui for her telling lies.

Step V  Key sentences
The purpose of this step is to let the students know the meanings of the key sentences and let them repeat them fluently.
T: We have known the text well. Now let’s remember the key sentences and repeat them fluently.
Ss: 1. His fried rice was hot but did not taste of fat.
2. Tired of all that fat? Want to be thinner? Only slimming food served here.
3. I will take all that fat off you in two weeks if you eat here every day.
4. It was not giving its customers energy-giving food!
5. Something terrible must have happened if Maochang was not coming to eat with him as he always did.
6. He wondered if he should go to the library to find out.
7. He couldn’t have Yong Hui getting away with telling people lies.

Step VI   Homework
T: Today is the first class of the unit. You ought to preview this unit completely after the class. In this way you will make your study easy. Today’s homework is:
1. Retell the text.
1)Use the first person to retell the story.
2)Try to use proper prepositions and conjunctions.
2. Prepare for the language learning and do Using Words and Expressions on WB (Page 49-50).
