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, too. 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 am. She ran about two miles before she went to work. But Barbara’s legs and back started to hurt. She did some exercises 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 exercises after work.” Her legs and back don’t hurt anymore.

Today, doctors are learning more about chronobiology (时间生物学), the study of biology clocks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep at the same time every night and to eat only when they’re hungry. Also, doctors discovered that some illness, such as heart attacks(心脏病), occur(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 medicine at night, they may prevent a heart attack in the morning.

Many doctors believe chronobiology can help us live healthier lives. It may be the right time to listen to these doctors!

Swimming and English Learning

Can you swim? Do you like swimming? Yes? Well, how can you learn to swim? I think the best way is to go into the water and learn. I’m afraid you’ll never learn to swim just by reading books about swimming or looking at others swimming. It’s the same with the English study. We must practice, practice and practice.

Listening and speaking are very important for beginners. The children in English-speaking countries first listen to others. Then they try to imitate and speak. We can listen to English programs on radio. You may just understand a few words. It doesn’t matter. Just be relaxed, try to catch every word.

Somebody may be a good listener. But he dare not speak. He’s afraid of making mistakes. You know we sometimes make mistakes when we speak Chinese. Don’t be afraid. We must be brave. If you really want to learn English well, you must try to speak with everyone so long as he knows English. Whether you know him or not is not important when there’s nobody to talk with, you can talk to yourself in English. It’s interesting and also a good way to practice your spoken English. Remember, the more you speak, the fewer mistakes you’ll make.

Reading and writing are more important for senior school students. First we must choose the books we’re interested in. A lot of reading will improve your language sense. This is the most important.

Keep writing English diaries. We can also write English articles. You may even post them to English magazines. Don’t be afraid of failure. Failure is the mother of success.

Easier said than done. Well, let’s do more practice from now on. I’m sure you’ll learn English well in this way.
