Many people weigh more than they want to. They eat too much or do not exercise enough. They choose unhealthy food, or snacks too often. Weight gain (增加) happens when people eat more food than their bodies use.     1     Dieting (节食) means taking in less food.

It has been shown that writing down everything you eat and drink—as soon as possible—helps you to lose weight. Writing down what you eat is called keeping a “food diary”.

If you write down everything you eat and drink in a day, you might be surprised! It is easy to forget the food you eat while you are reading, working or watching TV.     2     Each snack might seem small, but they add up.

    4     Without the diary, you might forget about the biscuits with your coffee, the soft drink at lunch, or the mid-afternoon banana. You might forget having extra pieces of pizza!

Keeping a food diary will also make you aware (意识到) if you are not eating enough different kinds of foods. It will show if you are not eating enough vegetables or fruit, or if you are drinking too many sweet drinks.     5     They can help you write down what you eat and you will lose weight faster.

5 . I’m Stephen Curry, a basketball player in NBA. As a sportsman, I have a healthy eating habit. Every day I eat fish, chicken, beef and a rainbow (彩虹). Well, not a rainbow in the sky but a healthy rainbow out of different colors of fruits and vegetables.

A red apple can help you keep your heart (心脏) strong. An orange carrot has vitamin A. It can help keep your eyes healthy. I eat them for breakfast.

A yellow banana is good for your body. Yellow corns (玉米) can help keep your stomach (胃) healthy. Green beans are rich in vitamin K. They make your teeth (牙齿) strong. I like them for lunch.

After dinner, I always have some blueberries (蓝莓). They’re good for memory (记忆).

To be healthy, we shouldn’t only eat one thing. Do you eat a rainbow a day?

How to keep healthy?

Good sleep is important.     1     A cup of milk before sleeping may help you get a good sleep. Go to bed at the same time at night and get up the same time in the morning.

    2     You can understand（理解）it easily. Your body needs food for morning activities. It helps you to work better. Your whole day will be more fun after you enjoy a good meal in the morning.

How often do you exercise? If you want to keep healthy, try to exercise at least half an hour every day.     3    

Studies show that the cold or flu virus（病毒）can live on our hands for long.     4    

    5     The oral examination（口腔检查）is not only good for the health of teeth, but also for the whole body.

8 . Moderation（自我调节）

Pay attention to how you lead your life most of the time. A healthy lifestyle is one that doesn’t take extremes （极端） as a way of life. Be moderate in what you do.

Eat well

It is important to pay attention to both what you eat and how you eat. As Socrates said: “You should eat to live ;not live to eat.” A different diet （饮食） with vegetables and fresh fruits is good for the brain. Also take time off for meals.

Exercise

Students must know the value of exercise because it plays a necessary part in counterbalancing （抵消）the stress（压力）responses produced in our bodies by having to meet exams.

Sleep

Students are getting less and less of sleep which might lead to more stress. The hours of sleep before midnight are thought to be the most helpful. For this reason students must re-regulate their body clock and go to bed and get up at regular time.

Express yourself

The way students feel about their work and other issues in their life plays a huge part in how they deal with stress. It is advisable that students should be realistic whatever happens in their lives.

To sum up, studies are really very important, but never at the expense（代价）of students’ physical and mental well-being. Besides, if students feel well they will be ready to face the challenges（挑战） of exams alive and kicking.

10 . My name is Judy. I’m a student from Yucai Middle School. I have a good friend. Her name is Rita. She doesn’t have good eating habits. She eats hamburgers every day. After dinner, Rita likes eating ice-cream. Rita is fat. Her mother doesn’t want her to be a fat girl. She thinks it’s not healthy to eat too many hamburgers and eat ice-cream after dinner.

Rita’s mother is a doctor(医生). She eats healthy food. She eats some bread and a banana for breakfast. For lunch, she eats a sandwich and some fruit. For dinner, she eats salad, chicken and an egg. Rita’s mother doesn’t eat ice-cream because she doesn’t want to be fat. And she likes doing sports. Her favorite sport is tennis. She thinks it’s relaxing and interesting.
