Book 3 Unit 2 Healthy eatingCOME AND EAT HERE (1)Wang Peiwei sat in his empty restaurant feeling very frustrated. It had been a very strange morning. Usually he got up early and prepared his menu of mutton kebabs, roast pork and fried rice. Then by lunchtime they would all be sold. His restaurant ought to be full of people. But not today! Why was it so? What could have happened? He thought of his mutton kebabs and fatty pork cooked in the hottest, finest oil. His fried rice was hot but did not taste of fat. His cola was sugary and cold and his ice cream was made of eggs, milk, cream and fruit. “Nothing could have been better,” he thought. Suddenly he saw his friend Li Maochang hurrying by. “Hello, Maochang,”he called, “Your usual?” But Maochang seemed not to hear. What was the matter? Something terrible must have happened if Maochang was not coming to eat with him as he always did.Pengwei followed Li Maochang into a newly-opened small restaurant at the end of the street. There was a sign in the window.Tired of all that fat? Want to be thinner?Come inside to Yong Hui’s slimming restaurant.Only slimming foods served here.Make yourself thin again.Curiosity drove Wang Pengwei inside. It was full of people. A verythin lady came forward. “Welcome!” she said, “My name is Yong Hui.I will take all that fat off you in two weeks if you eat here every day.” Then she gave a menu to Wang Peiwei. There were only two kinds of food and one drink on it: raw vegetables, fruit and water. Wang Peiwei was amazed at this and especially at the prices. It cost more than a good meal in his own restaurant. He could not believe his eyes! He threw away the menu and hurried outside. On his way home he thought about his own menu. Did it make people fat? He wondered if he should go to the library to find out. He couldn’t have Yong Hui getting away with telling people lies! He had better do some research!After reading, he realised what was wrong with Yong Hui’s restaurant. It was not giving its customers energy-giving food! After eating in her restaurant people would become tired very quickly. Perhaps this was a way to win his customers back! Peng Wei wrote his own sign. It said: Want to feel fit?Come and eat here!Our food gives you energy all day!The competition between the two restaurants was on!Daisy wished to be ___so that she could wear all the latest, cool clothes designed for the young. She decided to do some ___into what foods should be eaten to become thinner. She learned that one of the ___of not eating enough was to become very tired quickly. When shewent to the doctor, he told her she could be thinner as well as healthy if she ate more vegetables like beans,___and ___.So she did. She felt very fit when she started eating more ___foods as well as her usual energy–giving foods. She even began to enjoy eating all the vegetables___rather than cooked. She soon looked like a model!COME AND EAT HERE (2)The next day Wang Pengwei’s restaurant was nearly full and he felt happier. Perhaps he would be able to earn his living after all and not have to close his restaurant. He did not look forward to being in debt because his restaurant was no longer popular. He smiled .But the smile left his face when he saw Yong Hui walking in. She did not look happy but glared at him as she moved round the customers. “May I ask w hat you were doing in my restaurant yesterday? I thought you were a new customer and now I find you came only to spy on me and my menu,” she shouted. “Please excuse me,” he calmly explained,“I wanted to know where all my customers had gone yesterday. I followed one of them and found them in your restaurant. I don’t want to upset you but I found your menu so limited that I stopped worrying and started advertising the benefits of my food. Why don’t you sit down and try a meal?”Yong Hui agreed to stay and soon they were both enjoying the dumplings, fatty pork and cola.When they were served the ice cream Yong Hui began to look ill. “I feel sick with all this fat and heavy food,”she said,“I miss my vegetables and fruit.”Wang Pengwei was just enjoying a secon d plate of dumplings so he sighed.“yes,”he added,“and I would miss my dumplings and fatty pork. But don’t you tired quickly?” “Well, now you mention it. I do have to rest a lot, ”admitted Yong Hui. “But don’t you think it would be better if you were a bit thinner?” she asked Wang Pengwei. “I’m sure you would feel much healthier.”They began chatting about menus and balanced diets. “My research has shown me that neither your restaurant nor mine offers a balanced diet,”explained Pengwei,“I don’t offer enough fibre and you don’t offer enough body–building or energy–giving foods. Perhaps we ought to combine our menus and provide a balanced menu with foods full of energy and fibre. ”So that is what they did ,They served raw vegetables with the hamburgers and boiled the potatoes rather than fried them .Then they served fresh fruit with ice cream. In this way they cut down the fat and increased the fibre in the meal. Their balanced menus became such a success that before long Wang Pengwei became slimmer and Yong Hui heavier. After some time the found that their business cooperation had turned into a personal one .Finally they got married and lived happily ever after!THE TOWN HAS TO DECIDE(At the meeting that evening there are two speakers: one for and one against building a McDonald’s restaurant.)FOR BUILDING A MCDONALD’SI was excited when I heard that our community(社区) was to have its own McDonald’s restaurant. I thought about all those young people who would not have to go to the next town to buy their favourite burgers and chips. McDonald’s cares about healthy eating too and works with scientists to provide food that is of high quality,safe and healthy. It is also cheap .They often provide salads as well as burgers and chips. You can also choose between cola and milk shakes(奶昔). Of course it also means more work for our area that needs jobs badly. McDonald’s say the y are interested in doing what is right for the community and being a good neighbour. So I think they will be concerned about providing parking for the cars in our main street. Many of our young people will be only too happy to work for it. They make a promise to the people that work for them. They say,“We value you, your growing skills and your help to the company.”I can see nothing but good if this company comes to build its restaurant in our town.AGAINST BUILDING A MCDONALD’SI am very worried about McD onald’s building a restaurant in ourhometown. We are a small community and we enjoy our local dishes. I am not sure if McDonald’s food is as healthy as they say in their advertisements. When scientists look at it carefully they find high levels of fat, sugar and salt. This is very worrying. Too many young people are getting fat through eating too much fatty food. McDonald’s is not giving young people a good idea of what a healthy diet should be. Local Chinese food ,on the other hand, is full of fresh vegetables and fresh meat and fish. The food at a McDonald’s restaurant is always the same so I wonder if it is made or brought in from elsewhere. Although it is freshly cooked ,it must be less healthy than our own locally grown and cooked Chinese food.I also worry about all those cars bringing people to buy food in McDonald’s. First, there would be petrol fumes(气体),which would make our clean air dirty. Second, there’s the problem of all those cars that try to park and prevent other cars from moving quickly through our town. Third, what will happen to all the food containers if people decide to eat on the side of the road just out of town? Will they just throw them on the ground?I’m sure many young people would be happy to work for McDonald’s but will they be treated fairly(公平地)?In American, McDonald’s does not allow Unions to operate in its restaurants and these are people who speak up for the workers. If ,as they say, the workers are happy with themwhy should they fear some workers joining a Union?So when I consider the food, the cars and the jobs, I think we should not allow McDonald’s to build their restauran t in our town.。
