　　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．”

[　　]
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．

阅读理解，阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

　　When you are talking to somebody at a party, do you focus entirely on the person you are speaking with or does your attention keep jumping around the room to all the other people there? General1y, if the person is someone you really want to talk to, you will focus on him．Most other people will only get about half of your attention．

　　You may think that this is OK, because if you don't really want to talk to him, then what does it matter if you don't give him your full attention? Consider two things．First, you may just not realize the importance of that conversation．If you are at a networking meeting and you hope to meet the CEO of Company X, but you end up talking to someone who has a low-level job at a different company, then you may let your attention wander(走神)as you speak to him．But maybe you don't realize that this person has already met the CEO and could introduce you．Do you think he will do that if he feels you don't really care about speaking to him? This doesn't mean you need to spend the whole time talking to him．Five or ten minutes of real attentive(专心的)conversation can be worth 30 minutes to an hour of partial attention．

　　Second, whether you want to speak to someone is based on the situation．You can love your wife, but if she tries to talk to you while you are watching something you like on TV, where is your attention going? Make your own decision, but if you want her to feel valued, give her your 100％ attention．The nice thing is that in many cases you can give her your attention for a few minutes and then return to what you were doing．You miss very little, she feels valued, and all is good．
