Everyone likes living in a clean and comfortable environment. If the envionment(环境) is bad, it will affect（影响）our bodies, and make us not feel well. Sometimes we may be terribly ill.

It’s germ that makes us ill. There are germs everywhere, They are very small and you can’t find them with your own eyes, but you can see them with a microscope（显微镜）. They are very small and there may be hundreds of them on a very small thing, Germs can always be found in the dirty water. When we look at dirty water under the microscope, we shall see them in it. Germs can also be found in air and dust（灰尘）. If you cut your finger, some of the dust from the floor may go into it, and you will have much pain in it. Sometimes the germs will go into all of your boby, and you will have pain everywhere.
To keep us healthy, we should try to our best to make our environment become cleaner and tidier. This needs us to act together.
【小题1】The writer tell us that________.

Healthy eating habit along with regular exercise is the only way to become fit. If you have the correct number of calories and exercise regularly, you will lose weight, keep fit, and feel great, too.
During your teenage years, it is important to give your body the energy it needs. If you skip (跳过) meals, you won’t get enough calories, and then you will feel tired. By the way, calorie is just another word for energy. About 50% of your calories should come from rice, bread, vegetables and fruit. You also need to drink a lot of water, 6 to 8 glasses a day. Water helps keep your system clean. Drinking enough water will make your skin better and make you healthy.
Exercise is something that can help to make you look good, feel good and be healthy. Experts suggest that teenagers spend at least 30 minutes exercising a day, five times a week. That is easy to do! You can walk or ride your bike to school, and do sports at school. However, teenagers often give up sports, saying they have no time left after their studies. In fact, doing exercise can help them sleep better at night and increase their ability to focus on their study.
If you follow the suggestions above, you will look and feel much better and become fit.
【小题1】What’s the main idea of this passage?

What will you do if weight keeps going up? Here are ideas to help you stay healthy:
Don’t sit around
Stay active. Try to exercise 30 to 60 minutes every day. Your exercise doesn’t have to be hard. Start small. Take the stairs instead of the elevator(电梯). Walk or ride a bike to places such as school or a friend’s house. Help your mum with housework, such as cleaning windows or the bathroom. It all burns fat. Make changes from time to time so you don’t get bored: Try running, biking, skating. There are many choices. Don’t spend long hours watching TV or playing video games. Even reading a book burns more fat.
Eat healthy
Truly different kinds of food and get enough fruits and vegetables each day. Drink water and low fat milk instead of soft drinks like Cola. Stay away from fast food. Eat when you are hungry, not when you are bored or because you can’t think of anything else to. Don’t eat meals or snacks while watching TV because you’ll probably end up eating more than you need. Some worry so much about their weight that they don’t eat breakfast. This is a bad idea. Teenagers need enough food. If not, you won’t get the nutrients you need to grow normally.
Don’t rush to go on a diet
Even if you are a little heavier than your fiends, you still may be normal. Remember to talk to doctors and your parents before you decide to lose weight.

Walk to school every day? That will work, but not if you like sleep in. If you like bad smells and crowding(拥挤), the bus might be your best Choice. But why not a bicycle? A bicycle will get you there faster than your feet and will save your money.
This is why you see more bicycles than any other kind of transportation in China, about 500 million of them. That’s close to one for every two people in the whole country. But if you survey your class at school, you may will find a higher rate(比率).
Bicycles became popular because they are fun for people and at the same time help develop a strong body. No vehicle is better than a bicycle for enjoying an autumn weekend outside the city with parents or friends. You can travel on small, quiet paths. You also can park your bicycle beside the path wherever you want to stop to admire the beauty.
Cycling every day helps people build with city healthier hearts and stronger muscles(肌肉). Scientists say a 30-minute ride every day can help you lose weight.
Today, bicycles also are popular with city planners. They see bicycles as a good way to reduce heavy traffic. Unlike buses, bicycles produce no exhaust(尾气) and don’t burn energy. Many countries are encouraging more daily use of bicycles.

A
Do you feel a little sleepy after lunch? Well, that’s normal (正常). Your body slows down then. What should you do about it? Don’t drink coffee! Instead, take a nap (打盹).
It’s good to have a daily nap. First of all, you are more energetic after napping. You remember things better and make fewer mistakes. Also, you can learn things more easily after taking a nap. A nap may improve your self-confidence (自信) and make you more active. It may even cheer you up. But, there are some rules you should think about taking a nap.
First, take a nap in the middle of day.
Next, a 20-minute nap is best. If you sleep longer, you may fall into a deep sleep. After waking from a deep sleep, you will feel worse. Also, you should set an alarm clock. That way, you can fully relax during your nap. You won’t have to keep looking at the clock so you don’t sleep too much.
Now, the next time you feel sleepy after lunch, don’t get stressed. Put your head down, close your eyes, and take a nap.

Almost every day, we discuss the topic of health, especially for kids. But what is health? “Health” means eating well, getting enough exercise, and having a healthy weight. Let’s read the following rules. They can help you stay healthy.
(1). Eat a variety of food, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite food. Remember that we can only get the nutrition (营养) we need by eating different kinds of food, especially fruit and vegetables.
(2). Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty of calcium (钙) to grow strong bones, and milk is rich in it. Every day, you should drink at least three cups of milk, when you are 9 years old or older. You should also try to have less sugary drinks, like soda and coca. They include a lot of sugar. Sugar only includes calories (热量), not important nutrition.
(3). Listen to your body. When you are eating, notice how your body feels. When your stomach feels comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can make you unhealthy and fat.
(4). Limit screen time. What’s screen time? It’s the amount of time you spend watching TV, movies and playing computer games. The more time you spend on these sitting-down activities, the less time you spend playing sports, like basketball, and doing other activities like riding and swimming. Try to spend no more than 2 hours a day on screen time.
