     It's 2009. You feel sick, so you go to the doctor. She checks your fever, looks at your throat, and asks

what you've been thinking about lately. When you leave, she gives you some medicine, but also a list of

thinking skills that you are supposed to practice daily. She says that the way you think is causing some of

your illness.

     Doctors and other scientists who study the human mind and try to explain why people behave in the way

that they do, called psychologists, are starting to believe it. You know that your brain is connected to every

part of your body through your nervous system (神经系统). Now scientists have proved that how you think

and feel can have an influence on the health of your body.

     Stress (压力, 紧张) is caused whenever there is a problem or a change in your life. Of course, everybody

has stress more or less; nobody's life is perfect. In fact, stress is necessary. Without stress, we would never

learn anything or grow or change. We would probably be bored to death. But too much stress can hurt you.

It can weaken your body's protection so that you are more likely to catch diseases. It can even make you more

likely to have an accident.

     When you feel stress, your brain sends a message to your body to produce a chemical called adrenaline (肾

上腺素) . Adrenaline speeds up your breathing and your heartbeat. Today you have a different kind of stress.

Problems like endless homework or troubles with your family are the kind of things you can't fight or run away

from, so you don't use up all that adrenaline.lt just stays bottled up inside you, and that's what can do something

bad to you.

     What can you do about stress? First, you can try to find ways to change things so you aren't under so much

stress. You can set up a plan to finish homework or go to a doctor or a psychologist to try to work things out

with your family or your friends. But sometimes you can't change a stressful situation. Sometimes you don't

even want to. A big change might be a good change, but it will still be stressful.

     The link (关联) between your body and brain works in two ways. Your body can help your mind deal with

stress. If you are under stress, you need to take especially good care of your body. It's important to get enough

sleep and eat nutritious meals. Some people take a vitamin-mineral pill every day. Another thing that you can do

is daily exercise, If you go walking or do aerobic dancing or work out at the gym, you give your body a chance

to burn up some of that adrenaline. Of course, a person who isn't used to much physical activity should start

slowly. Anyone with a continuing physical problem should check with a doctor before starting any exercise

programs.

A. illness and abilities

2. Which of the following is true according to the passage?

A. You shouldn't go to the gym if you are under stress.

B. One can do his homework to burn up adrenaline.

C. Diseases and accidents are caused by stress.

D. Everyone needs stress to improve himself.

A. it's difficult to change a stressful situation

B. it's not stressful when a good change takes place

C. a big change will cause another stressful situation

D. a stressful situation can't be changed without any effort

A. The Body-Brain Link

B. The Causes of Stress

We often don' t give importance to minor things thinking they won' t matter. But at times, some things look very minor but their result can be really powerful. Here are some of the efforts which can change the relationship between parents and children.

Pat your child when he loses:May it be failure in the class, or on the field, speak words of encouragement to your child. The trust and confidence in your relationship will go to another level. After all, words of encouragement during failure are more valuable than words of praise after success.

Give him importance, like a member of the family:Hang his painting in your room or in the office, take his opinion when you are buying furniture for the house. Your child will believe in himself and be a winner throughout.

Share your own experience when your child makes a mistake:When you see your child lying or stealing, share with him the mistakes you made in your life. He' 11 know it is all right to make mistakes and that he can share with you anything.

Appreciate at least one quality in your child every day:Each day look at what qualities your child possesses and appreciate him, maybe for his caring attitude, his dance skills or his observation power. Tell him how proud you are of him because of those qualities.

Become his age before bedtime:Jump on the bed, have pillow fights, act silly, dance—become a child with your child for sometime. You' 11 forget all your day's stress.

Try these minor things; you' 11 see the love deepen and the relationship blossom.
