After a year of preparing herself, Laura Dekker has been given permission to sail around the world. “I was so happy that I almost jumped into the river,” Laura said, after learning of the court’s verdict(判决).
The 14-year-old was born on a ship in the South Pacific, and currently lives with her father on a boat. When child protection agencies heard about her plan to sail alone, they took the case to court and prevented her from making such a dangerous voyage.
Since the decision, though, Laura had been preparing with her father to convince the court that she was ready. Later on, she received the books and other materials she would need for school while she was at sea. She added safety equipment to a new, big ship. And she took her first aid course to learn several survival skills, like how to put out fires on the boat, take care of her own injuries and deal with lack of sleep. She also planned a safer course --- adding alternate routes(备用路径) to avoid pirate attacks, and planning a course that would have her on dry land as she moved from port to port across the globe.
Even with all of the added preparations, the trip still has its risks. In early June, 16-year-old Abby Sunderland, an American, had to abandon(放弃) her attempt to become the youngest sailor to travel around the world. Her ship’s mast(桅杆) broke due to rough waters in the Indian Ocean, and she was rescued by a French fishing ship.
Laura plans to take longer than Abby for her voyage, and is using a larger and more stable boat. If she finished successfully in less than two years, she will take the title from current record-holder Jessica Watson, of Australia, who was 16 when she completed the journey.
【小题1】Which of the following is TRUE of Laura?

A．how Laura convinced the court

B．why Laura needed to study at sea

C．how Laura prepared for the voyage

D．where Laura could avoid pirate attacks

People who have lost the ability to understand or use words due to brain damage are called aphasics(失语症患者). Such patients can be extremely good at something else. From the changing expressions on speakers’ faces and the tones of their voices, they can tell lies from truths.

Doctors studying the human brain have given a number of examples of this amazing power of aphasics. Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage.

Recently, scientists carried out tests to see if all that was said about aphasics was true. They studied a mixed group of people. Some were normal; others were aphasics. It was proved that the aphasics were far ahead of the normal people in recognizing false speeches — in most cases, the normal people were fooled by words, but the aphasics were not.

Some years ago, Dr. Oliver Sacks wrote in his book about his experiences with aphasics. He mentioned a particular case in a hospital. Some aphasics were watching the president giving a speech on TV. Since the president had been an actor earlier, making a good speech was no problem for him. He was trying to put his feelings into every word of his speech.

But his way of speaking had the opposite effect on the patients. They didn’t seem to believe him. Instead, they burst into laughter. The aphasics knew that the president did not mean a word of what he was saying. He was lying!

Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words. However, according to Dr. Sacks, they are more gifted than normal people. Normal people may get carried away by words. Aphasics seem to understand human expressions better, though they cannot understand words.

45. What is so surprsing about aphasics?

   A. They can fool other people.                B. They can find out the hidden drugs.

   C. They can understand language better.        D. They can tell whether people are lying.

46. How did the scientists study aphasics?

   A. By asking them to watch TV together.        B. By organizing them into acting groups.

   C. By comparing them with normal people.      D. By giving them chances to speak on TV.

47. What do we learn from this text?

   A. What ones says reflects how one feels.

   B. Aphasics have richer feelings than others.

   C. Normal people often tell lies in their speeches.

   D. People poor at one thing can be good at another.

Nuclear radiation（核辐射）has a certain mystery, partly because it cannot be detected（探测） by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being outright by killing masses of cells in important organs. Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated（放射治疗）and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
