Teaching procedures & ways
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
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...?
sugar
cakes or bananas
cakes
fat
chocolate or chicken
chocolate
fiber
pork or cabbage
cabbage
protein
eggs or cream
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
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
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.
Wang Pengwei’s restaurant
Yong Hui’s restaurant
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
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.
Explanation
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
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
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).
