LISTENING TEXT 1
Part 1
MIKE: Ohhh, ouch, my stomach hurts!
MUM: What's wrong, Mike?
MIKE: Oh, my stomach hurts. I must have eaten too much today. .
MUM: Well, what did you eat?
MIKE: For breakfast, I had two pieces of chocolate, a glass of coke and two cookies.
MUM: That isn't a very healthy breakfast. What else did you eat?
MIKE: Around 8:30 I was hungry again, so I ate an apple and a bag of potato chips.
MUM: Uh-huh.
MIKE: And then I had a couple of sandwiches at ten. MUM: That's a lot of food! Did you eat anything else?
MIKE: Well, yes, I had lunch, too.
MUM: What did you have for lunch?
MIKE: Hmm, let me see, I had two hamburgers, two large orders of French fries, an apple pie, and a large milkshake.
MUM: Oh, my! Well, no wonder your stomach hurts. But maybe we should go to see the doctor just to be sure.
Answers:
1 He has a stomachache.
2 Two pieces chocolate, a glass of coke, and two cookies.
3 Answers will vary since Ss are asked their opinions.
LISTENING TEXT 2:
DOCTOR: Hi, Mike. Hi, Mrs. Peterson. How are you?
MUM: I'm fine, thanks. But Mike has a stomach¬ache. He ate too much today. All junk food.
DOCTOR: Well, let's take a look. Come here, Mike. Where does it hurt?
MIKE: On the left side, right here.
DOCTOR: Here?
MIKE: Ouch! Yes!
DOCTOR: Hmm. Let me check and see if you have a fever. Put this in your mouth.
MIKE: Hmmffgg.
DOCTOR: Now, let's see. No, your temperature is nor¬mal. Your mum's right - you probably just ate too much. Here, take these pills tonight and tomorrow morning and see if you feel better. If anything changes or you don't feel better, give me a call.
MUM: Thank you, doctor.
MIKE: Ouch. Yeah, thanks, doctor.
Answers:
1 His left side hurts.
2 No, he doesn't. His temperature is normal.
3 Take some pills and call him if there is a problem.
Step 4 Speaking practice
　 Everyone wants to be healthy and strong. But sometimes we are not feeling well. When we re ill, we d better go and see a doctor and the doctor will look over us and give us some advice. Now we’re going to practice some everyday English used by doctors and patients. Here are three situations for you. Choose one of them and make up a dialogue with your partner according to the example given and then act out.
Sample dialogue 1:
D= Doctor; L = Lily
D: What seems to be the trouble, Lily?
L: I'm not sure. My back hurts but so do my legs.
D: Oh? Let's have a look. Does your back hurt here?
L: No, a little lower.
D: How about here?
L: Ouch. Yes, right there. Ohhh.
D: Show me where your legs hurt.
L: They hurt behind my knees and here on this part. D: That's called the calf of your leg. Well, you might have two problems.
L: Two problems? Oh no, is that serious?
D: I don't think so. Have you done any heavy lifting recently?
L: Why, yes. Last night I helped my cousin carry some boxes of books to her room. We had to walk all the way from her school.
D: I see. Well, you have a sore back from lifting too much. Have your mum rub it for you.
L: OK. But what about my legs?
D: Nothing to worry about them. They're just tired from so much walking! So take a rest today.
L: Oh, great! No housework! Thanks, Doctor.
Sample dialogue 2
D = Doctor; P = Patient
D: Good morning. How are you feeling today?
P: Good morning, doctor. Oh, I'm not feeling so good. D: What's the matter?
P: I'm coughing all the time.
D: I see. And do you have a fever?
P: Yes, I think I do. And I have a terrible headache.
D: OK. Lie down and let me examine you. Let's check your temperature. (The doctor takes the patient's tem¬perature.) Well, you have a bit of a fever, but nothing to worry about. Let's listen to your cough. (The doc¬tor asks the patient to cough and listens to the patient's chest and breathing.) It sounds ok. You have a cough, but your lungs sound fine. Do you have difficulty breathing?
P: No. I just have a cough.
D: I think you have a cold. I will give you some medi¬cine for your cough. Drink lots of water and get plenty of rest. Stay in bed until your fever goes down. If the fever doesn't go down, or if it goes up, please call me immediately.
P: Thank you, doctor.
Sample dialogue 3
D = Doctor; P = Patient
P: Ouch! Doctor, doctor, please help me. Ow, it hurts!
D: Calm down. Where does it hurt?
P: My arm hurts, right there. I fell off my bike and hurt my arm.
D: Let me have a look. Hmm, that's a big bruise. Can you move your fingers?
P: Yes, but it hurts.
D: It looks like your arm might be broken. We are going to have to x-ray it to make sure. Please go with the nurse.

（三）教学过程
Step 2 Pre-reading discussions
Answers to the exercises:
1 No correct answer: all three choices can provide en¬ergy, but at different levels depending on when they are eaten (consumed) and how much (quantity) is con¬sumed.
2 Three meals is common but answers may vary. The second part requires self-reflection.
3 Water is consumed in different liquids. Encourage Ss to consider this fact in their responses.
4 In the "Warming Up," the Ss had to consider what is and isn't a snack. Their response to this question should reinforce, or add to, their understanding of just what a snack is.
Step 3 Reading
Read the text carefully again, and give the students some explanations.
①　Reading
1. What do traditional diets often have? too much fat and too many calories
2. What can help our body fight disease and give us energy? vitamins, fiber and minerals
3. What contains a lot of protein? fish, meat and beans
4. Why do some people become vegetarians?
Because they believe it is healthier not to eat meat or they think we should not kill animals for food.

Step 4 Listening to the reading passage
Play the tape for the students to listen and follow.
Step 5 Post-reading
Answers:
1 It means the food we need to keep our bodies healthy and active. Green foods are organic foods, that is, foods that are grown and produced naturally. But not all green foods are actually green in color.
2 Any food that tastes good; any food that is healthy; any food that is a vegetable; any food that is organic; any food that is safe.
3 We have more foods to choose from and many of the foods are not produced organically; We are busier than in past years so we now have less time to eat than before; More snack foods are available since more people like to eat between meals; now many people are paying more attention to their health because others remind them to; some people refuse to eat foods produced with chemicals because they believe they are unsafe; some people care as much about the health and safety of animals as people so they refuse to eat meat; people today expect food to taste good and still be healthy, and they now have more choices when they go to market; many people don’t get enough nutrition from their food so they take supplements, especially vitamin pills.
4.Sample answers:
●People go to fast food restaurants because they are quick and convenient.
●Too much sugar and fat will make you as big as a whale.
●Some people start crash diets because they are in too much of a hurry to lose weight naturally.
●To keep a balanced diet, we must first make a list of the foods we most often eat.

Step 3 Vocabulary
Answers to the exercises:
1 nutrients 2 diet 3 fibre/fiber 4 minerals 5 fat 6 sugar 7 protein 8 calories
Step 4 Grammar
Ss must use one of the modal verbs listed in the direc¬tions but expect the advice they provide in their answers to vary greatly. The important thing is for Ss to use each of the modal verbs (and their negative forms) listed at least once and to add different kinds of advice which a doctor might give to a patient. Encourage Ss to be spe¬cific and detailed in their advice.
Sample answers to Grammar Exercise 1:
1 You have a bit of a fever. You should stay home to¬day.
2 You had better change your diet if you want to stay healthy.
3 If you are sick, you had better not go outside in the rain.
4 Before you eat an apple, you should make sure it is ripe.
5 You don't look well. You ought to get some rest.
6 You have a bad cough. You had better take this cough medicine twice a day.
7 This medicine will make you sleepy. You had better not drive your car until this afternoon.
8 There's nothing seriously wrong with your knee, but you should try not to run on it.
Note: In American English, had better and had better not are used much less often because it is considered stronger than should. Indeed, it can sometimes be taken as a threat, as in you had better do it ... or else, indicat¬ing that negative consequences will result from inac¬tion.
Instructions to Grammar Exercise 2:
The purpose of this exercise is to provide Ss with prac¬tice in applying grammar to a real-life situation, in this case a newspaper advice letter. Have Ss read and dis¬cuss the model before doing it themselves. Remind Ss to follow a logical sequence when giving their advice to Xiao Lin.
Sample advice for Grammar Exercise 2:
1 First, you ought to talk to your friend about it before the dinner.
2 But if you don't want to ask her, then you had better do what she does at the table.
3 Of course, you should try all the food you are of¬fered.
4 However, you shouldn't be too nervous. After all, you're her guest and she will try her best to make you feel comfortable.

参考答案：1 F 2.T 3.F 4.F 5F
Suggested Answers:
Instructions Point out to Ss that a good snack doesn't have to be something you buy at the grocery store and eat out of a bag. As the article says, it can be a piece of frui_ or something simple you make like a salad. Ask Ss to 'rank their favourite snacks from "most healthy" to "least healthy" on the blackboard and try to reach an agreement about their list of rankings.
Extension Have small groups of Ss go on the Internet and do a word search with the phrase "snack recipes." Ask them to write down or print out a recipe they find interesting. Now have each group present their list to their classmates by writing the ingredients on the board along with the name of the dish and either a photo or sketch of what it should look like when it is ready to eat. Then ask each group leader to give you the recipe for how to use the ingredients step-by-step. Now invite another group to guess how the ingredients should be prepared and have them write their recipe on the black¬board. This can be a competition to see which group can come closest to writing the correct recipe.
Sample recipe:
Crispy Beef Roll
Ingredients:
300 grams (0.66 lb) ground beef 350 grams (0.77Ib) bread crumbs 2 eggs
1 gram (1/4 tsp) MSG 2 grams (1/3 tsp) .salt 10 grams (2 tsp) cooking wine
5 grams (1/6 oz) finely cut scallions 5 grams (1/6 oz) chopped ginger
10 grams (1 1/2 tbsp) dry cornstarch 300 grams (3/5 cup) cooking oil
Directions:
1 Add to the ground beef the" salt, MSG, cooking wine, scallions, ginger and 5 g (1 tbsp) of the dry corn¬ starch, and mix well until it becomes sticky.
2 Whip the eggs in a bowl.
3 Divide the ground beef into 3 portions and shape into long rolls 5 cm (2 inches) in diameter and 15 cm (6 inches) in length. Steam over strong fire for 10 minutes. When the rolls cool off, cover them with the whipped egg and bread crumbs.
4 Heat the oil in a wok to 110-135 °C (230-275 OF) and deepfry the beef rolls until they are a golden color. Drain off the oil.
5 Cut in a slanting way to divide the rolls into sections 3 cm (1.2 inches) long each. Put on a plate and serve.
Features: Golden in color.
Taste: Crispy outside and tender inside, the rolls are really delicious.
Give the students some explanations when necessary.
Step 6 Necessary language points
Today we ve done some listening and speaking, and learn how to give advice and some everyday English used between doctors and patients.
1>Even if we choose nutritious food for our main meals, we probably still need to refuel now and then.
　Even if　[用法]同even though，即使；尽管
　now and then　[用法]同a little now and a little then; every now and then，有时候
2>Most fruits are naturally sweet and we can eat them just the way they are.
　just the way they are　[用法]意同in the way that they are
3>There are many recipes for simple and healthy snacks that taste great and keep us going.
　taste 　[用法]连系动词，相关用法见高一上册 unit 12
Step 7 Writing
Ask the students to think about the question. They may work in pairs and make a list of reasons for or against eating meat, and then use the list to write their para¬graph. You may also discuss the question with the whole class before the students write the paragraph.
Sample 1
DON'T EAT MEAT!
We should not eat meat or use animal products. A vegetarian diet is healthier than a diet with lots of meat. Vegetables and fruits contain more minerals and vita¬mins than animal products, so we should eat bananas instead of bacon. In the past, we had no choice, but to¬day we know better. It is not right to kill animals for food or clothing and animals should not be kept in small boxes or cages. We must stop treating animals in this way. Finally, we must stop eating meat if we want to survive. Animal farms use up too much of our resources. We should use that land for other kinds of farming that
give us more food. If we stop eating meat, we will treat our animals better, protect our planet and use our re¬sources in a better way. So please don't touch that ham¬burger, steak or sausage and don't buy that fur coat-help make the world better!
Sample 2
DON'T TOUCH MY STEAK!
Animal meat is delicious and nutritious and it should be part of everyone's diet. We should eat vegetables too, of course, but we should not become vegetarians or vegans. Meat tastes good and is healthy. It contains many of the nutrients we need to keep our body going. A good steak, for example, is an excellent source of protein. If we don't eat meat, we will get weak and sick. A lot of people would go hungry if we stopped eating meat.
Eating meat is natural. We are part of nature and ani¬mals are meant to be eaten. Some people may think that it is cruel to kill animals for food or clothes. But they forget that we are all part of nature. It is not cruel to kill animals, as long as we treat them well and only kill the animals we need for food. We must not kill them for fun and we should not treat them badly. It is true that some animals are kept in small cages and have a very bad life, but that doesn't mean that it is wrong to eat meat.
If we treat our animals well, we can enjoy a good steak when we are hungry and wear a leather jacket when we are cold. So please, all you vegans and vegetarians, don't touch my steak!

Step 3 Speaking practice
　 Everyone wants to be healthy and strong. But sometimes we are not feeling well. When we re ill, we d better go and see a doctor and the doctor will look over us and give us some advice. Now we’re going to practice some everyday English used by doctors and patients. Here are three situations for you. Choose one of them and make up a dialogue with your partner according to the example given and then act out.
Sample Dialogue1
A: Good evening, ma' am. May I take your order?
B: Yes. I'm a vegetarian, so I don't want to eat any meat. Do you have any vegetarian dishes?
A: Yes, we do. We have onion soup and two salads. We also have spicy tofu and a vegetarian burger.
B: Hmm. Well, I do like spicy food. Maybe I'll try the tofu. You said you had two salads, what are they?
A: We have a house salad and a tomato salad.
B: What's the house salad?
A: It's lettuce, tomato, onion, mushrooms and corn.
B: That sounds good. I'd like a house salad, please.
A: OK, so one spicy tofu and one house salad. What would you like to drink?
B: Orange juice, please.
Sample Dialogue2
A: Excuse me, waiter! Could I order, please? I'm very hungry!
B: Of course. What would you like?
A: Oh, I like all kinds of food. I'll eat anything as long as I get a lot of it!
B: I see. Well, in that case, I recommend that you order a steak.
A: Well, yes, but I'm worried that it may not be enough. What does it come with?
B: It comes with two vegetables and your choice of French fries or bread rolls.
A: Can I have both fries and bread rolls?
B: Sure. And perhaps you'd like a salad?
A: Good idea! I'd like a regular house salad. Oh, and I'd like some dessert, too.
B: We have apple pie and ice cream.
A: Great. I'll take the apple pie, please.
Sample Dialogue 3
A: Good evening. May I take your order?
B: Yes, please. I'm ordering dinner for three friends and I need your help. One of them is a vegetarian.
A: Well, we have a vegetarian burger. Do you think your friend would like that?
B: Yes, that's a good idea. My other friend does not like spicy food.'
A: In that case, I'd recommend either a BLT sandwich or a chicken roll-up.
B: I think a BLT sandwich will be fine. She likes sand¬wiches. What does it come with?
A: It comes with a choice of French fries or potato crisps.
B: Potato crisps. Now, my third friend loves Chinese food. What do you recommend?
A: The Sichuan-style pork is very popular.
B: OK, let's try that. Oh, and I'd like a vegetarian burger, too.
A: Right, so that's two vegetarian burgers, a BLT with crisps and a Sichuan pork. What would you like to drink?
A: Ah, that's easy: four diet cokes.

Step 5 Writing
Sample 1
Dear Emily,
The best way to lose weight is to exercise and eat healthy food. Don't try to lose weight fast, because that can be dangerous. Try to make small changes in your eating habits: eat fruit instead of sweets and don't eat too much fast food. You should also try to get more exercise. Why not try going for a walk every day? A long walk with a friend is fun and is also a good way to improve your health.
Yours,
Sample 2
Dear Peter,
People who play basketball and other sports ought to eat food that gives them a lot of energy. Try to eat lots of carbohydrates and protein. Keep a balanced diet and make sure to eat noodles, vegetables and fruit. You should eat a healthy meal and rest before you train or play a game. You must also remember to drink lots of water. You needn't worry too much about your size and strength; good players come in all sizes.
Yours,
Sample 3
Dear Steve,
It sounds like you need to take a look at your diet. You probably need to eat a better breakfast and you should eat fruit instead of sweets. You have to make sure that your diet is balanced and that you get enough exercise. By eating right and keeping fit, you will have more en¬ergy and you won't feel tired.
Yours,
（四）总结扩展
Step 5
Have we ever tiled to make snacks or seen our mother make snacks. Let’s try to write the recipe for your favorite dish. Before writing, you should read Tips first.
Sample 1
DON'T EAT MEAT!
We should not eat meat or use animal products. A vegetarian diet is healthier than a diet with lots of meat. Vegetables and fruits contain more minerals and vita¬mins than animal products, so we should eat bananas instead of bacon. In the past, we had no choice, but to¬day we know better. It is not right to kill animals for food or clothing and animals should not be kept in small boxes or cages. We must stop treating animals in this way. Finally, we must stop eating meat if we want to survive. Animal farms use up too much of our resources. We should use that land for other kinds of farming that
give us more food. If we stop eating meat, we will treat our animals better, protect our planet and use our re¬sources in a better way. So please don't touch that ham¬burger, steak or sausage and don't buy that fur coat-help make the world better!
Sample 2
DON'T TOUCH MY STEAK!
Animal meat is delicious and nutritious and it should be part of everyone's diet. We should eat vegetables too, of course, but we should not become vegetarians or vegans. Meat tastes good and is healthy. It contains many of the nutrients we need to keep our body going. A good steak, for example, is an excellent source of protein. If we don't eat meat, we will get weak and sick. A lot of people would go hungry if we stopped eating meat.
Eating meat is natural. We are part of nature and ani¬mals are meant to be eaten. Some people may think that it is cruel to kill animals for food or clothes. But they forget that we are all part of nature. It is not cruel to kill animals, as long as we treat them well and only kill the animals we need for food. We must not kill them for fun and we should not treat them badly. It is true that some animals are kept in small cages and have a very bad life, but that doesn't mean that it is wrong to eat meat.
If we treat our animals well, we can enjoy a good steak when we are hungry and wear a leather jacket when we are cold. So please, all you vegans and vegetarians, don't touch my steak!
