There are 50 students in our class, 20 girls and 30 boys. I did a survey（调查）by asking them questions about how they keep healthy.

Forty students say they love doing exercise.     1     But girls think baseball is not easy for them. They would like to play ping-pong three times a week.

    2     He runs fastest in our class. He runs for 30 minutes every day. Every year, he takes part in the school sports meet and he always wins in the race. He hopes that he can be in the Olympic Games in the future.

Tony is good at swimming. He usually goes to the swimming club once a week in winter and four times a week in summer.     3    

Most of my classmates always eat healthy food, such as meat, fruit and vegetables.     4     Twenty students drink juice three times a week. But other students love eating junk food, especially Sally. Eating too much junk food and not doing exercise are bad for her. She is very fat and she always says, “    5    ” But she never does what she says.

I think everyone should do more exercise and eat green food to keep fit.

3 . “You are what you eat.” Nutrition experts often use this saying to improve better eating habits.

To many people, hamburgers, hot dogs, fried chicken and pizza are their favorites. It’s true that many Americans do eat those “junk food”. But others choose more healthy eating habits. Some even go “all natural”. They refuse to eat any food prepared with chemicals or additives(添加物).

What we put in our mouths does become a part of us. To have a healthy diet, you may need to make some changes. Changing your eating habits a little bit at a time may be easier and it can lead to better health. Here are some ways for you:

Keep more fruits, vegetables, low-fat dairy products（乳制品）and whole-grain foods at home and at work.

Try to eat a family meal every day at the dining table. This will help you focus on eating healthy meals and let you control what you eat.

Pack a healthy lunch and snacks for work. Put your snacks on a plate instead of eating from the package. This helps you control how much you eat.

Don’t skip or miss meals, and be sure to list your snacks. If you don’t feel hungry, you may end up choosing an unhealthy snack. If you often feel too hungry, it can cause you to focus a lot on food. Eat your meals with others when you can. That can make you feel relaxed and enjoy your meals, and don’t eat too fast. Try to make healthy eating a pleasure, not a chore.

Do you want to be in good health? Try to do the following things!

Drink eight cups of water every day.     1     If you feel thirsty, just have a cup of water.

Get enough calcium（钙）. Your bones need it. Milk has more calcium. You may also drink soya milk.

    2     Breakfast gives you everything your body needs for the morning, so do not forget your breakfast.

Go for a walk every day. Walking is good exercise, and people need exercise for good health.     3    

Use your brain every day. For example, you can do the crossword puzzle or read a new book.

Have a rest for about twenty minutes when you are tired. You may do something different to have a break.     4     Stretch（伸展）for five minutes after sitting for one or two hours. Stretching your arms and legs is good for your body.

Why not have a try? If you do all the things every day, I’m sure you’ll feel good enough.     5    

6 . Yesterday, Danny ate lunch at a restaurant with his family. Later that night, he had food poisoning(中毒). He wanted to know how it happened.

Danny learned about a few reasons(理由)for food poisoning(中毒).

The first reason is bacteria in the food. Bacteria live in a lot of food and they live in meat, eggs and seafood most often. If you cook the food in a right way, you can make the bacteria die in it.

Another way to get food poisoning is from parasites(寄生虫). They often live in meat, but could live on vegetables, too. If you don’t cook the food in a right way, these parasites may start living in your body.

The third way that you can get food poisoning is by eating the food with toxins(毒素)in it. Sometimes the food gets toxins naturally, and sometimes the toxins come from insect spray(喷雾杀虫剂). So you must wash the food carefully before you eat or cook it.

The last way that people get food poisoning is from allergens(过敏原). Some people are just allergic to some food, and they may feel very uncomfortable after eating it.

Danny decided he would choose food carefully and cook it in a right way before he ate it in the future. That was important. He never wanted to feel this way again.

7 . Where does your meat come from? Maybe a cow, pig or chicken. Did you know that we can make “meat” out of plants as well?

Plant-based meat is not real meat, but looks and tastes like the real thing. It’s made out of plants like potatoes and peas. It’s getting more popular around the world these days. In the US, plant-based meat company Beyond Meat will sell its products (产品) in 5,000 more stores by the end of September. In June, KFC started to sell plant-based burgers and chicken nuggets in Shanghai, Guangzhou, Shenzhen and Beijing. At the same time, Pizza Hut in China has also added plant-based meat to its menu.

Scientists say this food is better for the environment. Producing meat makes too many greenhouse gases (温室气体). If everyone in the world stopped eating meat, it would reduce greenhouse gas emissions (排放) by two-thirds, according to Plant Proteins.

Eating plant-based food is also healthier. Many people get heart disease (心脏病) because they eat too much meat. Would you like to try plant-based meat?

8 . Everybody wants to be healthy. Food is very important. There is a lot of healthy food. You can have more bananas, apples, oranges, tomatoes because fruit and vegetables are good for your health. But don’t eat too much chocolate. It’s bad for your teeth.

Healthy food can make you strong and happy. Remember there is a saying, “An apple a day keeps the doctor away.” Sports can also keep you healthy. Get up early and play sports every day. Don’t be lazy! You will be healthy and happy.

9 . Balancing(平衡) your diet(饮食) is important. But how to balance your diet? Let me tell you.

Breakfast is the most important meal of a day. If you don’t have time to sit down and have a healthy breakfast, try vegetable juice before you go to school. This is better than coffee.

Eat less salt(盐). Foods like hot dogs have a lot of salt in them. So eat less or give them up.

Stay away from foods with too much fat(脂肪). You can eat vegetables, fruits, fish and chicken. They are healthy for you. For example, you can eat chicken hamburgers instead of(而不是) beef hamburgers.

Don’t often go out for lunch. You can let your mother make lunch at home and take it to school. Eat some cabbage or salads with chicken. Also, drink lots of water every day.

Balancing your diet to relax is as important as exercise.

10 . We can make our eyes healthy in many ways. Don’t read in the sun. Watch less TV. Do eye exercises every day. But do you know we can also have healthy eyes by eating some food that is good for eyes?

Kale	Kale is a dark green vegetable. It looks like a cabbage. There is vitamin（维生素）A in it. If you eat kale often, you will still have healthy eyes when you are old. And vitamin A can help you see well in the dark.
Salmon	Salmon is a kind of fish. It has a lot of Omega（脂肪酸）. If you often feel you have dry eyes, Omega in salmon can help you. You don’t need to eat a lot each time. A little will be OK.
Bananas	Bananas are popular fruits for people. They are very good for eyes. There is Beta-carotene（ β-胡萝卜素）in them. When you have sore eyes, Beta-carotene can make you feel better.
Sweet food	Kids like sweet food, such as candy, honey and ice cream. They are delicious. You may not know they are good food for short-sighted（近视）, don’t eat too much. They are bad for teeth.
