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 smoking.”

1. 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

2. We know from the passage that a low dose of Ecstasy ______.

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

3.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.

4. 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

D. people have long known that repeated use of the drug damages brain cells

.Can you imagine your doctor warning that taking a bath could be unhealthy? In the early 1800s, many doctors thought that bathtubs(浴缸) could carry diseases, so they advised against their use. The advice wasn’t based on personal experience, because few of the doctors owned bathtubs. The White House did not even have a bathtub until 1851.

In the 19th century, only one home out of six had a bathroom. A child took only one bath a week. On Saturday nights, children all lined up for their turns to wash in a wooden bathtub in the kitchen. Mothers had to boil the water on the stove and carry it over to fill the bathtub. It’s no wonder that children could not jump into a bathtub as they do today.

When the first bathtubs were introduced, even their makers weren’t sure whether the new fashion would last. They advertised their products as water containers that “could be used as bathing tubs”.

The bathtub became popular in America shortly after World War I. By then most middle-class families had indoor taps. At first most bathtubs were made of wood, but as the popularity of the product increased, so did the creativity of bathtub makers. Before porcelain(瓷) bathtubs there were rubber ones like the plastic swimming pools kids use today. In the past few years owners often invited guests to see them. They told their friends how wonderful baths in these bathtubs could be.

Now doctors no longer warn that bathtubs carry diseases. Instead, they tell their patients about the benefits of frequent bathing in the bathtubs. Maybe one of the best reasons why doctors encourage frequent trips to the bathtub is that bathed patients smell better!

47. Many doctors in the past were against using bathtubs because ______.

A. they didn’t have their own bathtubs

B. they thought bathtubs could carry diseases.

C. the children might hurt themselves in the bathtubs

D. bathtubs were too expensive for the common families

48. Why couldn’t children jump into a tub in the 19th century as they do today?

A. It was unhealthy to do so.      B. The bathtubs were not enough.

C. Mothers were always busy.     D. The bathtubs were made of wood.

49. Which of the following is true according to the text?

A. Some different materials can be used to make bathtubs.

B. In the 19th century only one home out of seven had a bathroom.

C. The bathtub became popular when they were introduced to the market.

D. Children prefer the bathtubs made of plastic to those made of porcelain.

50. It can be inferred from the last paragraph that ______.

A. all the doctors have bathtubs in their homes

B. the doctors have realized the advantages of bathtubs

C. the doctors will make lots of money by advertising bathtubs

D. the patients should take a bath before going to see a doctor
