题目列表(包括答案和解析)
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.”
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
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
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
D. people have long known that repeated use of the drug damages brain cells
A newly-published study has shown that loneliness can spread from one person to another, like a disease.
Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 individuals are taking part.
Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.
University of Chicago psychologist John Cacioppo led the recent study. He and other researchers attempted to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.
Having a social connection with a lonely person increased the chances that another individual would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone’s loneliness.
The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.
The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.
Loneliness has been linked to health problems like depression and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.
The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.
What is true about the Framingham Study?
A. It was only conducted in 1948. B. It involves more than 12,000 participants.

Which statement about the spread of loneliness is true?
A. The spreading effect was the second strongest among friends.
B. No spreading effect was found on husbands and wives.
C. Women are more likely to be affected than men.
D. Brothers are more easily affected than neighbors.
If you make 10 more friends in a year, the days of your feeling loneliness will be reduced by .
A. 48 days B. 25 days C. 20 days D. 15 days
What is the main idea of the passage?
