Most of us use alarm clocks to wake up at the right time for school or work. We look at our watches to know the right time for the bus or train. However, there is also a right time to eat, sleep, exercise, and take medicine. We can’t look at a clock for the right time for these activities. We must listen to the clock inside our bodies: the biological clock.
Barbara Wells exercised every morning. She woke up at 6:00 a.m. She ran about two miles before she went to work. But Barbara’s legs and back started to hurt. She did some exercise before she ran. But her legs and back still hurt. She ran slower, but the pain didn’t stop. Barbara talked to her doctor. The doctor said, “Don’t run in the morning. Try to exercise later in the day. That is the time when your body is at the right temperature for exercise after work.” Her legs and back didn’t hurt anymore.
Today, doctors are learning more about chronobiology(n.生物钟学), the study of biological(adj.生物的) clocks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep on time every night and to eat only when they’re hungry. Also, doctors discovered that some illnesses, such as heat attacks, occur(v.发生)most often in the morning. This information tells them that the best time to take heart medication may be at night. When patients take heart medication(n.药物)at night, they may prevent a heart attack in the morning.
Many doctors believe chronobiology(生物钟) can help us live healthier lives. It may be the right time to listen to these doctors!Do we all have biological clocks inside our bodies?

When you are ill, you must be unhappy because your body becomes hot, and there are pains all over. You don’t want to work. You stay in bed, feeling terrible.
What makes you ill? They are germs. Germs are everywhere. They are very small and you can’t see them with your eyes, but you can find them with a microscope（显微镜）. They are very small and there could be lots of them on or in a very small thing.
Germs are always in the dirty water. When you look at dirty water under a microscope, you will see them in it. So your parents will not let you drink dirty water.
People can also find germs in the air and dust. If you cut your finger, and if some of the dust goes into the finger, it will become big and red, and you will have much pain. Sometimes they will go into your body and you will have pain everywhere.

The rules（规则，常规） in American schools
Greetings
You needn’t greet your teachers when you come into a very big class. If you are late for class, you may go into the classroom quietly. But you should say sorry to the teacher after class.
Answering questions
Don’t talk when somebody else is speaking. If you have something to say, you have to wait. When someone is speaking, you shouldn’t interrupt him or her. If you want to answer the teacher’s questions, you may stand up and speak loudly. It’s impolite to keep quiet when your teacher asks you questions. If you don’t know the answers, you can say “I’m sorry”.
Other interesting rules
Some American schools don’t allow students to wear caps, sunglasses or too large trousers. And they can’t bring any bananas to school. The school bags for the students are usually sheer （透明的）, so teachers can find what’s in it easily.If you are late for class in American schools, what should you do?
