The mystery had reached its climax（高潮）：The man had undoubtedly been murdered．However, no one present knew who could have killed such a kind person． It was therefore time to call in the great detective, who gave one searching glance at the corpse（尸体）, and then used a microscope．
“Aha!” he jumped as he picked a hair off the dead man’s coat．“The mystery is a mystery no longer．We have only to find the man who lost this hair, and the criminal will be in our hands．” The chain of logic was complete, and the detective started to do his search．
For four days and four nights he moved unobserved through the streets of New York, scanning closely every face, looking for a man who had lost a hair．On the fifth day he discovered a man pretending to be a tourist, and his head was enveloped in a cap reaching below his ears．The man was about to board the Gloritania, and the detective lost no time in following him on board．
“Arrest him!” shouted the detective, and then, drawing himself to his full height, he took out the hair．“This is his,” said the great detective, “and it proves his guilt．”
“Remove his hat,” ordered the ship’s captain firmly．
It was discovered that the man had no hair．
“Aha!” said the great detective without a moment’s hesitation． “He has committed not one murder, but about one million!”

I told my friend Graham, "I often walk two miles from my house to the town centre. Unfortunately, there is a big hill on the way." He replied, "You should say 'fortunately’." He explained that I should be glad for the extra exercise that the hill gave.
I thought he was right. My attitude to the hill has now changed. As I approach the foot of the hill and prepare to climb, I tell myself that this hill will help me lose weight and get fit. This hill is my friend. I have a smile of satisfaction as I reach the top of the hill.
Problems are to be faced. We cannot achieve anything with an easy life. Helen Keller once wrote that "Character cannot be developed in ease and quiet. Only through experiences of trial and suffering can the soul be strengthened ..."

London’s Chinese community dates back to the 18th century, when a small number of Chinese sailors moved to the city to work in Limehouse, east London. As time went by, other Chinese people came to this area and Limehouse began to be known as "Chinatown". At the start of the 20th century, there were just 545 Chinese people in Britain. However, this situation changed greatly after the Second World War. At this time, many farmers in Hong Kong lost their jobs, and decided to move to London. In the 1950s, a small Chinese restaurant opened in central London. Many British people visited it and said that Chinese food was wonderful! Suddenly, Chinese restaurants started opening in every part of the city. Instead of too little work, the new Chinese immigrants (移民) now found that they had too much! Most of the new immigrants enjoyed their lives and the chances they were offered. Many asked their friends and relatives to join them from their hometowns, and a lot of families were reunited again at this time.
As time went by, London’s Chinese community became more and more successful. The sons and daughters of the first restaurant workers, encouraged by their parents, studied very hard at school and university. And most got highly-paid jobs. As a result, increasing numbers of Chinese families left Chinatown and moved to the more expensive places. Chinatown, however, is still as lively as ever, and a must-see for any visitor to London.From the passage, we can learn that the first members of "Chinatown" were _____.

When we donate（捐献） blood, a small amount is usually taken in advance for at least ABO and Rh systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh + or Rh-.
The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances(物质) contained in each type, the four groups must be transfused carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital.
There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The least common is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world.Which of the following shown the correct relationships in blood transfusions?

The text mainly tells us ______.
| A．about the basic types of human blood |
| B．what kind of blood is the most common |

Long long ago, there was a small seed（种子）. Because it was only a seed, nobody noticed it. Thus, feeling inferior (低级的), the seed gave no importance to his existence. Then one day, a wind picked him up and threw him on an open field in the sun. Later, he was given rain. Years later he saw a traveler sitting by his side. "Thank you God for this. I really needed some rest," he heard the traveler say. "What are you talking about?" the seed quickly asked. He thought the man was making fun of him. No one ever spoke to him like that. "Who just spoke?" the shocked man asked. "It is me, a seed." "A seed?" the man looked at the big tree. "Are you joking? You are no seed. You are a big tree!" "Really?" "Yes! Why else do you think people come here?" "What do they come here for?" "To feel your shade (树阴)! Don’t tell me you didn’t know you had grown over time. "A moment passed. The seed thought and smiled for the first time in his life. The years of torture (磨难) by the sun and the rain finally helped him grow up. "Oh! That means I’m not a little seed anymore!

You are watching a film in which two men are having a fight. They hit one another hard. At the start they only fight with their fists. But soon they begin hitting one another over the heads with chairs. And so it goes on until one of the men crashes through a window and falls thirty feet to the ground below. He is dead!Of course he isn't really dead. With any luck he isn't even hurt. Why? Because the men who fall out of high windows or jump from fast moving trains are professionals. They do this for a living. These men are called stuntmen. That is to say, they perform tricks. There are two sides to their work. They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall on to hard ground but on to empty cardboard boxes covered with a mattress (床垫). Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar! But although their work depends on trick of this sort, it also requires a high degree of skill and training. Often a stuntman' s success depends on careful timing. For example, when he is "blown up" in a battle scene, he has to jump out of the way of the explosion just at the right moment.
Naturally stuntmen are well paid for their work, but they lead dangerous lives. They often get seriously injured, and sometimes killed. A Norwegian stuntman, for example, skied over the edge of a cliff (悬崖) a thousand feet high. His parachute failed to open, and he was killed. In spite of all the risks, this is no longer a profession for men only. Men no longer dress up as women when actresses have to perform some dangerous action. For nowadays there are stuntgirls too.Stuntmen are those who ______.
| A．often dress up as actors |
| B．prefer to lead dangerous lives |
| C．often perform seemingly dangerous actions |
| D．often fight each other for their lives |
Stuntmen earn their living by ______.
| A．playing their dirty tricks |
| B．selling their special skills |

Which of the following is the main factor of a successful performance?
| A．Strength. | B．Speed. |
| C．Exactness. | D．Carefulness. |
What can be inferred from the authors example of the Norwegian stuntman?
| A．Sometimes an accident can occur to a stuntman. |
| B．The percentage of serious accidents is high. |
| C．Parachutes must be of good quality. |
