A single night of taking the drug Ecstasy can cause serious brain damage and hasten the【C1】______of Parkinson’s disease, scientists say. Just two to three Ecstasy tablets-a quantity that thousands of clubbers take during raves-can permanently 【C2】______ brain cells that affect movement and【C3】______, according to American research that 【C4】______ the drug to Parkinson’ s for the first time.
A study by a team at Johns Hopkins University in Baltimore, Maryland, 【C5】______ monkeys and baboons found that both species of primate【C6】______irreversible damage to key cells 【C7】______ dopamine neurons, which are lost in Parkinson’ s, after receiving three low doses of Ecstasy at three-hour【C8】______.
The study is particularly significant because baboons are one of the best animal models for the human【C9】______. George Ricaurte, who led the research, said that widespread【C10】______of the drug may already be【C11】______victims of such neurological damage. "The most troubling【C12】______is that young adults using Ecstasy may be【C13】______their risk for 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-faceted damage that Ecstasy can do【C14】______users. We’ve long known that repeated use damages serotonin brain cells. This study shows that even very【C15】______use can have long-lasting effects【C16】______many different brain systems. It sends an important message to young people: don’t【C17】______with your own brain."
Janet Betts, the Essex mother whose daughter Leah died after a single Ecstasy tablet in 1995, said: "This comes as no【C18】______. People can’t see the effects at first, and they’re in permanent denial, saying it’s not going to happen to them. But we’ll see the【C19】______later, just as we have【C20】______smoking."
【C7】
选项
A、marked
B、titled
C、naming
D、called
答案
D
解析
考查动词辨析。此处是说这种主要的细胞被称为多巴胺神经细胞,由于是被动含义,因此只能在过去分词中选择。mark表示“作标记”;title表示“给予称号尤其是头衔”,放在此处均不合适,所以选D.called。
