The research was done by a Dr. Griffiths in England. He compared the behavior. of 15 regul

ar gamblers (赌徒) with those of 15 non-regular gamblers before and after they gambled. Both groups had increased heart rates (心率) during gambling because t was exciting. But the regular gamblers' heart rates went down almost straight after to game, while the non-regulars remained excited and had increased heart rates for longer.

When the heart beat increases, the body produces chemicals called endorphins which make you feel good. Dr. Griffiths thinks that regular gamblers lose this good feeling soon after a game and need to play again quickly to regain the pleasure.

He has also discovered that regular gamblers have different psychological reactions (心理反应) from non-regular gamblers. In an experiment where regular and non-regular gamblers thought aloud while playing, regular gamblers had far more unreasonable thoughts. In their minds they turned losses into near-wins. Dr. Griffiths thinks that nearly winning gives the gambler a high n the same way that a win would do.

Based on Dr. Griffiths' research, doctors suggest that one way to help regular gamblers to give up gambling is to give them beta-blockers — drugs that stop them getting a high in the first place.

Dr. Griffiths' research helps you find out______

A.which group of gamblers played the game better

B.a chemical to increase gamblers' heart beat

C.a way to help gamblers give up gambling

D.when gamblers should be given drugs

I don't ever want to talk about being a woman scientist again. There was a time in my life
when people asked constantly for stories about what it's like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space-lime and the nature of black holes.

At 19, when I began studying astrophysics, it did not bother me in the least to be the only woman in the classroom. But while earning my Ph. D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement—jobs, research papers, awards—was viewed through the lens of gender(性别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus(相对于) right brain, or nature versus nurture(培育), I would instantly fight fiercely on my behalf and all womankind.

Then one day a few years ago, out of my month came a sentence that would eventually become my reply to any and all provocations: I don't talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn't want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don't study sociology or political theory.

Today I research and teach at Barnard, a women's college in New York City. Recently, someone asked me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don't dismiss those concerns. Still, I don't tell them "war" stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that's a sight worth talking about.

Why doesn't the author want to talk about being a woman scientist again?

A.She feels unhappy working in male-dominated fields.

B.She is fed up with the issue of gender discrimination.

C.She is not good at telling stories of the kind.

D.She finds space research more important.

To paraphrase 18th-century statesman Edmund Burke, "all that is needed for the triumph of
a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights, movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal.

For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from or is tested in animals — no meat, no fur, no medicines. Asked if she opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes." Asked what will happen when epidemics return, she said, "Don't worry, scientists will find some way of using computers." Such well-meaning people just don't understand.

Scientists must communicate their message to the public in a compassionate, understandable way — in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother's hip replacement, a father's bypass operation, a baby's vaccinations, and even a pet's shots. To those who are unaware that animal research was needed to produce these treatments, as well as mew treatments and vaccines, animal research seems wasteful at best and cruel at worst.

Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.

The author begins his article with Edmund Burke's words to ______.

A.call on scientists to take some actions

B.criticize the misguided cause of animal rights

C.warn of the doom of biomedical research

D.show the triumph of the animal rights movement
