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

       In eighteen thirty, only a few miles away from what is now the great city of Cincinnan,  Ohio, lay a   36  and almost endless forest.

       The man's name was said to be Murlock. He   50   to be seventy years old, but he was really fifty. Something other than years had been the   51  of his aging.

       His hair and long, full beard were white.  His gray,   52   eyes were sunken.  His face was wrinkled. He was tall and thin with drooping shoulders—like someone with many   53  .

Twenty years ago, I drove a taxi for a living. One time I arrived in the middle of the night for a pickup at a building that was        except for a single light in a ground floor window. I walked to the door and knocked.

A small woman in her 80’s opened the door. I took her suitcase to the cab then returned to       her into the cab. She thanked me for my kindness. When we got in the taxi, she gave me a(n)      , then asked, “Could you drive through downtown ?”

“It’s not the         way,” I answered.

“Oh, I don’t mind,” she said. “I’m in no hurry. I’m on my way to a hospice (临终关怀医院).”

I looked in the rear view mirror. Her eyes were glistening.

“The doctor says I don’t have very long.”

I quietly reached over and        the meter (计程器). “What         would you like me to take?” I asked.

For the next two hours, we drove through the city. She showed me the building where she had once worked as an elevator operator. We drove through the neighborhood where she and her husband had lived. Sometimes she’d ask me to       in front of a particular building or corner and would sit staring into the darkness, saying nothing.

As the sun was       , she suddenly said: “I’m tired. Let’s go now.”

We drove in        to the address she had given me. There were people waiting for her and they put her in a wheelchair.

“How much do I have to pay you?” she asked, reaching into her purse.

“Nothing,” I said.

Almost without thinking, I bent and gave her a hug. She held onto me tightly.

“You gave an old woman a little moment of       ,” she said.

I squeezed her hand, then walked into the dim morning light. Behind me, a door shut.

I didn’t        any more passengers that shift. I drove aimlessly, lost in thought. We tend to think that our lives revolve around great moments. But great moments often   47  us unconsciously.
