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, 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 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 s
moking.” 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 Parkinson’s disease |

| A．won’t cause serious brain damage |
| B．can permanently destroy one’s brain cells |
| C．will result in immediate symptoms |
| D．may bring on Parkinson’s at once |
Why are squirrel monkeys and baboons involved in the experiments?
| A．Because their brain is similar to human being’s. |
| B．Because these animals usually take drugs. |
| C．Because these animals will soon get well after the experiment. |
D．Because there is a  model in the animals’ brains. |
The underlined word “This” in the last paragraph probably means that ______.
| A．Leah died after a single Ecstasy tablet in 1995 |
| B．taking drug has the same symptoms as smoking |
| C．occasional use of the drug can have long-lasting effects on the brain systems |

Holidaymakers who are bored with baking beaches and overheated hotel rooms head for a big igloo. Swedish businessman Nile Bergqvist is delighted with his new hotel, the world’s first igloo hotel. Built in a small town in Lapland, it has been attracting lots of visitors, but soon the fun will be over.
In two weeks’ time Bergqvist’s ice creation(作品) will be nothing more than a pool of water. “We don’t see it as a big problem,” he says. “We just look forward to replacing it.”
Bergqvist built his first igloo in 1991 for an art exhibition. It was so successful that he designed the present one, which measures roughly 200 square meters. Six workmen spent more than eight weeks piling 1,000 tons of snow onto a wooden base; when the snow froze, the base was removed. “The only wooden thing we have left in the igloo is the front door,” he says.
After their stay, all visitors receive a survival certificate recording their success. With no windows, nowhere to hang clothes and temperatures below 0℃, it may seem more like a survival test than a relaxing(轻松的) hotel break. “It’s great fun,” Bergqvist explains, “As well as a good start in survival training.”
The popularity of the igloo is beyond doubt: it is now attracting tourists from all over the world. At least 800 people have stayed at the igloo this season even though there are only 10 rooms. “You can get a lot of people in,” explains Bergqvist. “The beds are three meters wide by two meters long, and can fit at least four at one time.” Bergqvist designed and built the world’s first igloo hotel because ________.
