1 . Most people know how to keep their bodies healthy, but not many people think about how to keep their brains healthy. Brain health is very important. It can help to make your brain work better and to stay away from some brain problems, such as strokes (中风).

Our reporter Judy is speaking to Dr. Cortez, professor of psychiatry.

Dr. Cortez: We must eat healthily. One of the best ways for the brain to get energy is from wholegrain food, like wholemeal bread. They can keep the brain working hard for longer.

Judy: Is fat important? What kind of fats should we eat?

Dr. Cortez: The brain needs fat to work well. Fatty acids(脂肪酸) are healthy fats found in fish and nuts. Trans-fatty acids(反式脂肪酸) from fast food like hamburgers are not good for the brain. They may cause damage to the brain.

Judy: People talk about berries a lot. Are they a “super food”?

Dr. Cortez: Yes, berries are very good for the brain. Blueberries, strawberries and blackberries are full of something called antioxidants. They help the brain to stay healthy.

Judy: What about sleep?

Dr. Cortez: Sleep is important. It is difficult for your brain to work well if you don’t have enough sleep. But too much sleep is also bad. It can make you feel tired.

Judy: We know exercise is good for our bodies. Is it good for our brains?

Dr. Cortez: Yes, exercise is another good way to take care of the brain. It makes the blood(血) move to the brain more easily and quickly.

2 . It is no longer as easy as it once was to choose what to eat. Our eating habits have changed, so has our way of life, and what we need for our bodies is also different. Traditional diets often have too much fat. So we had better learn to make the right choices about what and how we eat.

When we choose what to buy and eat, we had better think whether the food will give us the nutrients (营养物质) we need. Some nutrients help build our bodies and make our bodies stronger. We eat fish, beef and beans because the nutrients in them are good for our muscles. We choose eggs, milk and other dairy products (奶制品), which are good for our bones and teeth. We eat bread, rice and noodles to get carbohydrates (糖类) from them. We choose vegetables and fruit to get vitamins, fiber and minerals.

But the choices we make are not just about nutrition (营养). Many people today choose what to eat according to their beliefs. Some people become vegetarians (素食主义者) because they believe it is healthier not to eat meat or they think we should not kill animals for food.

4 . Mr. Clark is a reporter（记者）from a TV station. He wants to know whether（是否）the students have healthy habits or not. Here are some of the students’ answers.

Mary White: Yeah! I think my habits are very healthy. Every day I get up early and go to bed early. Every morning I eat breakfast and eat well. I eat fruit and vegetables every day. And every day I play soccer for two hours with my friends.

Jimmy Brown: No, I don’t. I get up late so I have no time to eat breakfast. For lunch, I usually eat lots of hamburgers. I know they are not good for me but I like them. I never play sports. In the evening, after I finish my homework, I usually play computer games. I go to bed late, at about eleven o’clock.

Grace Miller: Yes. My habits are very good. I never eat unhealthy food. Ice-cream tastes good but I never eat it. It’s unhealthy. Every day I get up at six o’clock and go to bed at eight thirty. I eat well and play sports every day. I run with my father for half an hour in the morning. So, I am very healthy.

6 . Mr. Jenkins liked all kinds of delicious food. As an important officer, he was often asked to dinner. The shopkeepers tried their best to fawn on (巴结) him. They knew it was good for their business. The officer got fatter and fatter. He could hardly go upstairs at home and had to sleep downstairs. He often felt tired if he walked or did some housework. He was worried about it and had to go to see a doctor.

“Stop eating much fat (脂肪) and sugar, Mr. Jenkins,” said the doctor, “or it will be worse for your health!” It was difficult for the officer to do it. He wouldn’t do as the doctor said. Of course, he found something was wrong with his heart a few months later. Now he thought the doctor was right. And he had to be in hospital.

“You must lose weight, Sir,” said the doctor, “unless you want to die soon!”

“Could you tell me a way to lose weight, please?”

“You must do exercise first.”

“Which exercise?”

“To move your head from side to side when you’re invited to dinner!”

7 . Mrs. Lee goes to buy some fruit every day. Her family love fruit very much. Mrs. Lee likes apples. Her daughter likes pears and her son likes bananas. What does Mr. Lee like? He likes oranges. Mrs. Lee buys some tomatoes and eggs for dinner. Her favourite food is tomato and egg noodles.
