When you cut your skin, you bleed(流血). If a person loses a lot of blood, he will become ill and may die. Blood is very important. People have always known that. At one time, some people even drank blood to make them strong!

When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called "blood transfusion（输血）". The blood goes from the arm of the healthy person into the arm of the sick person.

But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups—O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely.

There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time.

We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood. The "blood bank" will give it to you.

I know what you’re thinking : pizza （比萨饼）? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to.
I know lots of women who skip breakfast （不吃早餐） , and they have a ton of different excuses for doing it . Some say they don’t have time, others think they’re “saving” calories （卡路里）, still others just don’t like breakfast food .
But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking , R , D , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
【小题1】The word “leftovers” in Paragraph 1 probably means__________.

Are you a man or a mouse? When people ask this question they want to know 31   you are a   32  person or a coward(懦夫). But you will never really know the answer to this question  33  you are tested in real life. Some people  34  they are brave but when they come face to face with real  35 , they act like cowards. Others think of themselves as cowards, but when they meet danger, they act like  36 .
Lenny had always thought of himself as a  37  person. He got worried before examinations. He worried about his job and health. All he wanted in life was to be safe and healthy.  38 , on January 15^th, 2002, a plane crashed into the Potomac River in Washington. Lenny went to the river to see what was happening. He saw a woman in the  39  water. Lenny did not feel afraid. He kept very  40  and did a very dangerous thing. He jumped into the Potomac, 41  to the woman, and kept her head  42  the water. Seventy-eight people died that day. Thank to Lenny, it was not  43 .
When you are in a very  44  situation and feel afraid, the body automatically produces a chemical in the blood. The chemical is called adrenalin(肾上腺素). 45 adrenalin in the blood system, you will feel stronger and stronger and are  46 to fight or run away. However, when you are absolutely terrified, the body can produce too much adrenalin. When this  47 , the muscles become very hard and you find you  48  move at all. You are then paralyzed(使瘫痪，使麻痹) with fear. This is  49  when we are very frightened, we sometimes say we’re “petrified”, which means “stone”. We are   very frightened 50  we become stonelike.
