A person has been badly injured in a car accident. It is necessary to give him a transfusion (输血) because he has lost much blood in the accident. However, special care must be taken in selecting new blood for him. If the blood is too different from his own, the transfusion can kill him.
There are four basic blood groups: A, B, AB and O. A single test can tell us a person’s blood group. Everybody is born with one of these four blood groups. People’s blood group, like hair colour, is inherited (继承) from parents.
Because the substances contained in each group are different, transfusion must be given carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can be given to any other group, so it is often called the universal donor. On the contrary, AB is sometimes called the universal recipient (接受者). However, before being given the transfusion, patients usually receive only salt or plasma (血浆) until their blood can be matched as exactly as possible. In this way, it is possible to avoid any bad results of the transfusion.
There is a relationship between our blood groups and our nationalities. Among the Europeans, about 42 percent are blood group A while 45 percent are blood group O. The rarest is blood group AB. However, some American Indian groups are nearly 100 percent blood group O.

Look at the center circles of Diagram (图) A and Diagram B. Which of the centre circles looks larger?
Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact , they are exactly the same size.
Then look at the picture on the right. What do you see? A vase ? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time.
"What's happening? Is something wrong with my eyes?" You may wonder at what you see. Don't worry. Here is how it goes:
When we look at things, our eyes send messages to our brains and then our brains interpret (解读) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it "Visual illusion" (视觉错误).
Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions.

“I believe you’re the right person to write an advice column (专栏) for the students called Dear Amy!” Jenny, editor of the school newspaper, said to Andy, who finally agreed to accept the job if Jenny promised not to tell it to anyone else.
At first it wasn’t too bad. Most of the letters he received were interesting and quite easy to answer. Then came a letter from a person named Joe.
“Dear Amy,” it began, “I’m in real trouble. I’ve wanted to be a songwriter all my life, but my parents don’t even let me take music lessons. I have a guitar, but they both get angry if I play. I’ve tried explaining, but they didn’t listen. I feel sad. Should I run away from home? Maybe that will make my parents agree.” The letter signed “Joe”.
Andy thought about this letter for a long time. Should he advise someone to run away from home? Probably not. But didn’t Joe have a right to be a songwriter if he wanted to? Andy thought hard, but couldn’t think out a good answer. Andy couldn’t sleep. He just worried about poor Joe.
At a bar a few days later, Eleanor, a girl in Andy’s maths class, sat down next to him and asked, “ What’s wrong with you? You look a little worried.”
“I guess I do,” said Andy.
“If you get a problem, why don’t you try writing to Dear Amy about it?” asked Eleanor.
Andy sighed. But Eleanor continued, “In fact, I guess Dear Amy is rather busy with other problems. She still hasn’t answered the phony letter I wrote her last week. You’d better read it — it may even make the most hard-hearted person cry! It was supposed to be from a songwriter named Joe.”

There is one word you must learn before you visit the USA. That is “Freeze”. Remember it has a special meaning besides the usual one. It means “stand still and don’t move”.

One evening in Los Angeles, someone rang the bell of a house. It was a dangerous area at night, so the owner of the house took his gun with him when he answered the door.
