题目内容

You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.

There are four basic types of blood; A, B, AB, and O. A simple test can make sure of a person's blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is received from parents.

The four groups must be transfused carefully. A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group; therefore, it is often called the universal donor (万能捐赠者). For the opposite reason, AB is sometimes called the universal recipient（接受者）. However, because so many reactions (反应) can happen in transfusions（输血）, patients usually receive only salt of plasma (liquid part of blood) until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way, it is possible to prevent the transfusion from any bad reactions.

A. Chapter One. …you probably have an image in your mind of what the “perfect’ or “ideal” body looks like. Try not to press yourself to look that way. Each person is born with genes that control the shape of his / her body. Everyone is different. It’s important to be comfortable with the body you have.
B. Chapter Two.…You use energy for everything you do. That energy comes from the food you eat. Too much food or too little exercise causes your body to store the extra energy in fat cells. But, if you exercise regularly and eat a healthy diet, you’ll feel healthier and stronger not to mention look great.
C. Chapter Three. … Your body runs best on foods high in carbohydrates and low in fat and sugar. Eating a healthy diet will provide your body with everything it needs to run smoothly. Your body breaks down proteins into amino acids(氨基酸), so you don’t need to take in the amino acids separately.

E. Chapter Five. …Always warm up and stretch for 5-10 minutes before you do strength or endurance exercises. Afterwards, take 10 minutes to cool down. Your heart should beat normally when you stop. Exercising with a group may help you to exercise regularly.
