A single night of taking the drug Ecstasy (摇头丸) can cause serious brain damage and speed up the start of Parkinson’s disease（帕金森综合症）, scientists say. Just two or three Ecstasy tablets can permanently destroy brain cells that affect movement and reasoning, according to American research that links the drug to Parkinson’s for the first time.
A study by a team at Johns Hopkins University in Baltimore, Maryland, involving squirrel monkeys and baboons (狒狒) found that both species suffered permanent damage to key cells, which are lost in Parkinson’s, after receiving three low doses（剂量）of Ecstasy at three-hour periods.
The study is particularly important because baboons are one of the best animal models for the human brain. George Ricaurte, who led the research, said that the widespread abuse of drug might have caused severe damage. “The most troubling result is that young adults using Ecstasy may be increasing their risk of developing Parkinsonism as they get older.”
Alan Leshner, a former director of the US National Institute on Drug Abuse, said, “This study emphasizes the multi-aspect damage that Ecstasy causes to users. We’ve long known that repeated use damages brain cells. But this study shows that even very occasional（偶尔） use can have long-lasting effects on many different brain systems. It sends an important message to young people: don’t experiment with your own brain.”
Janet Betts, a mother whose teenage daughter Leah died after a single Ecstasy tablet in 1995, said, “This comes as no surprise. But people can’t see the effects at first, and they say it won’t happen to them. We’ll see the symptoms later, just as we have with smoking.”The article is intended to ______.
| A．explain the bad effects of drugs on people’s health |
| B．warn young people of the risk of taking the drug Ecstasy |
| C．persuade people out of such bad habits as smoking and using drugs |
| D．tell us the links between the drug Ecstasy and the animal models |

| A．can permanently destroy one’s brain cells |
| B．can cause serious brain damage occasionally |

| A．Because these animals usually take drugs. |
| B．Because their brain is similar to human beings. |
| C．Because there is a model in the animals’ brains. |
| D．Because they will soon get well after the experiment. |

It doesn’t matter when or how much a person sleeps, but everyone needs some rest to stay alive. That’s what all doctors thought, until they heard about Al Herpin. Al Herpin, it was said, never slept. Could this be true? The doctors decided to see this strange man themselves.
Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.
The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by his strange continuous sleeplessness. They asked him a lot of questions, hoping to find an answer. They found only one answer that might explain this question. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason? No one could be sure.

After we meet people, it is up to us to make them our friends．Let us stop a moment and consider what really makes a friend. The major qualities like faithfulness, devotion, friendliness，flash through our minds. But it is the large number of very small particular qualities that make up one’s whole character, such as cheerfulness, friendliness and punctuality. After all, “to make a friend, be a friend” is not such a big and difficult order. Ther
e are particular favorable qualities, which attract others to us, and some fundamental psychological do’s and don’ts．
If you are in the presence of a shy person, talking and asking casual questions may bring him out of his shell. Think of what would be most acceptable to the other person for you to talk, or to listen. Either way, the goal is to make yourself pleasant．
Always remember to listen, but listen intelligently. To have anyone “hang on our words” is the most unnoticeably clever way in the world to please somebody．For a few extremely happy seconds we are the center of attraction，but when it is our turn to be audience，let us remember how we felt as the actor，and let’s be genuinely interested in what the other fellow is saying．
Other people will l
ike us, if we like them. If you want friends, keep your mind and heart open to friendship. Be alive to the other person’s world．This passage is mainly about________.

How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?
In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.
Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger foreasier walking across sandy surfaces, they are taller, to reach higher branches. They have shorter tusks（象牙）, and most importantly, longer trunks to dig for water in riverbeds.
Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families. They drink only every 3 –4 days, and can s
tore water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders – they seldom root up trees and break fewer branches, and thus maintain what little food sources are available. Young elephants may even eat the dung（粪便）of the female leader of a group when facing food shortage.
During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine（尿液）to make them muddy!
As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.The underlined part in Paragraph 2 means “ ”.
| A．remains in the African countries | B．drinks 120 liters of water a day |

Dad came in the midnight. We heard every sound, but we pretended to be asleep.
Next morning he looked weak and thin, sitting in a chair by the kitchen fire. The light of the fire shone through his long empty sleeve. Everything went as usual. Grandma found something to do in the bedroom. Grandpa went out for some water. Mother, with her back to us, was getting the cakes ready for breakfast.
But nothing was right. When grandma came out of the bedroom, she walked on tiptoe. When grandpa came back, he said nothing about the weather. At breakfast Mother passed us the fruit and said something, but her voice was too high.
At last my sister, Lou, pushed back her chair. “It’s your turn to wash the dishes.” But I had washed the dishes the night before. I said nothing because it was not right to quarrel in front of Dad just home with the empty sleeve.
“It is your turn,” Lou said again. I looked at her in surprise.
