2 . We all know a healthy lifestyle (生活方式) is important for us. Here are three students’ lifestyles. Whose lifestyle do you think is the healthiest (最健康的)?

Peter is very fat because he always eats a lot (许多). Every day,     1    . For dinner, he usually has three hamburgers and some ice-cream. He doesn’t likes doing exercise. He does exercise less than one hour a week. That’s why he is so fat.

Kate doesn’t eat too much food every day. Her breakfast is only an egg and     2    . She usually has some vegetables and milk for dinner. She doesn’t eat meat because     3    .

Su Jun, a Chinese boy, has an another name—Early. He gets up early every morning and then     4    . He also enjoys tennis and goes to the Tennis Club three to five times a week. He looks strong and healthy. He likes to eat noodles or dumplings with some vegetables for lunch. He often eats salad but     5    .

Now, what’s your answer?

3 . We have to study and work every day, so if we don’t have a strong body, we will do badly in them. Some people don’t know how to keep healthy.     1    

First, eat healthily. We must eat enough food and the food must be clean. Don’t eat too much or too little and eat different kinds of food, such as bread, meat, fish, eggs, milk, fruit and vegetables.     2     Meat, fish, eggs and milk help our bones (骨头) grow. Fruit and vegetables give us vitamins (维生素).     3    

Second, do more exercise.     4     And it is easy to get sick if we are too fat. Doing sports every day can help build ourselves up.

Last,     5     Never feel sad or worry about anything. And remember that keeping a good mood (情绪) is a good way to keep healthy, too.

This is David, an English boy. He is 12 years old. He loves hamburgers. He has one hamburger for breakfast, two hamburgers and two ice creams for lunch.     1     Three hamburgers and a coke (可乐).

Some scientists say, “     2     But if you eat them too much, it is not good for health.” If we have food like hamburgers too much, what can we get?

Scientists have an experiment (实验) on rats (老鼠) to find the answer.

Here are three groups (组) of rats: Group One have fruit and vegetables.     3     But they can only have hamburgers for one hour every day. Group Three have hamburgers and vegetables, too.     4     The rats in Group Three like hamburgers very much and always want them. After the experiment, they are the fattest.

Can it be the same as people? Some scientists say “Yes”. It is OK to love food like hamburgers. But having six hamburgers a day like David makes you fat. You don’t want to be too fat, right? Ice—cream is nice and cool. It’s OK to have one ice-cream after dinner. But it’s not OK to have five ice-creams after dinner.     5    

5 . Different foods help your body in different ways.     1     You need to eat the foods in different groups every day.

You need a lot from the grain (谷物) group every day. Rice and bread are in this group.     2    

Eat enough vegetables each day. Eating more vegetables can help you keep thin.

You also need some fruit each day.     3     That way you’ll eat more. You can drink a glass of apple juice. You can eat a banana or a pear. Eating fruit may also make you feel happy.

Try to drink milk each day. Two glasses are OK.     4    

You also need something from the meat group.     5     You need 80—120g meat a day to have strong muscles (肌肉).

Try not to eat many candies. They may taste good, but they don’t help you to grow strong or stay healthy.

Lisa is my pen pal.     1     She has a big family. Her grandparents are farmers.     2     Lisa lives with her parents and brother in the city (城市). Lisa’s father is a doctor and he works in a Children’s Hospital.     3     Many students like her very much. Lisa has a little brother.     4    

Lisa often has breakfast with her family at home. She often has eggs and milk for breakfast. She has lunch at school every day.     5     Lisa likes Chinese food very much. She wants to visit China and try Chinese food one day.
