[单项选择]It may sound like something out of a science fiction plot, but Oxford researchers say that modern conventional medicine is gradually developing ways to change the moral states of humans through pharmaceutical drugs, and thus control the way people think and act in various life situations. These new drugs will literally have the ability to disrupt an individual’s personal morality, and instead reprogram that person to believe and do whatever the drug designer has created that drug to do.
"Science has ignored the question of moral improvement so far, but it is now becoming a big debate," said Dr. Guy Kahane from the Oxford Centre for Neuroethics in the UK. "There is already a growing body of research you can describe in these terms. Studies show that certain drugs affect the ways people respond to moral dilemmas by increasing their ability to share in another’s feelings, group affiliation and by reducing aggression."
While this may sound good in theory,
A. induce crime among drug-takers
B. cause death if taken at a high dose
C. bring about moral improvement
D. make some patients feel lonely

[单项选择]Fish farming in the desert may at first sound like an anomaly, but in Israel over the last decade a scientific hunch has turned into a bustling business.
Scientists here say they realized they were no to something when they found that brackish water drilled from underground desert aquifers (含土水层) hundreds of feet deep could be used to raise warm-water fish. The geothermal water, less than one-tenth as saline as sea water, free of pollutants and a toasty 98 degrees on average, proved an ideal match.
"It was not simple to convince people that growing fish in the desert makes sense," said Samuel Appelbaum, a professor and fish biologist at the Jacob Blaustein Institutes for Desert Research at the Sede Boqer campus of Ben-Gurion University of the Negev.
"It is important to stop with the reputation that arid land is nonfertile, useless land," said Professor Appelbaum, who pioneered the concept of desert aquaculture in Israel in the late 1980s. "We should consider arid land wh
A. fresh water can be drilled from underground desert aquifers
B. the water drilled from the underground desert aquifers is only one-tenth as salty as sea water
C. the water drilled from the underground desert aquifers contains more nutritious elements than fresh water
D. the water drilled from the underground desert aquifers is not as hot as the sea water
