[单项选择]Study after study has shown what has come to be known as an "empathy gap" in people. In its simplest form, this means that when we are happy we have trouble identifying with someone who is sad, or when we’re angry we have difficulty understanding why someone is content. Basically, our ability to empathise with another person is dependent on the state we ourselves are in, and this has some interesting implications for public policy.
A recent study by Loran Nordgren of Northwestern University’s Kellogg School of Management, Mary-Hunter Morris of Harvard Law School, and George Loewenstein of Carnegie Mellon University, examined the empathy gap with regard to torture policy. Man’s propensity to turn monster has long been of interest to behaviourists and psychologists. Witness Philip Zimbardo’s prison experiment, or Stanley Milgram’s shock experiment. Both of those studies, along with many others, support the idea that our actions depend as much on context as on any inherent dispositio
A. We are hostile to those who win over us in sports competition.
B. We share our happiness and bear infliction in the road toward success.
C. We bring our fury under control when other people rebuke us.
D. We believe there is neither everlasting friendship nor eternal enmity.

Man has invented ways to keep warm, but how do animals defend themselves They cannot reason in the sense that man can, but nature has taken care of the animal kingdom by providing animals with special instincts (本能). One of these instincts is known as hibernation (冬眠).
"Sleeping like a dormouse (榛睡鼠)" is not only a common saying but is a reality. When winter comes, the dormouse and other hibernating animals have reached a well- nourished state. They eat very well in warmer days laying down fat in the tissues of their bodies and during hibernation this keeps them alive. Safe in their nests, or burrows (地洞), they sleep soundly until the warmth of spring arrives.
Bats, tortoises, snakes, frogs, even insects like butterflies, hibernate more or less completely. Some, like the squirrels (松鼠), sleep during coldest weather but are roused (弄醒) by a warm spell (暖流). During hibernation, th
A. It moves about to keep warm
B. It grows thicker fur
C. It stores fat before hibernation
D. It goes to warmer areas

Passage One
The study of genetics has given rise to a profitable new industry called biotechnology. As the name suggests, it blends biology and modem technology through such techniques as genetic engineering. Some of the new biotech as they are called, specialize in agriculture and are working enthusiastically to patent seeds that give a high yield, that resist disease, drought, and frost, and that reduce the need for hazardous chemicals. If such goals could be achieved, it would be most beneficial. But some have raised concerns about genetically engineered crops.
"In nature, genetic diversity is created within certain limits," says the book Genetic Engineering, Food, and Our Environment. "A rose can be crossed with a different kind of rose, but a rose will never cross with a potato. Genetic engineering, on the other hand, usually involves taking genes from one species and inserting them into another in an attempt to transfer a desired prope
A. by mixing different species
B. within the species itself
C. through natural selection
D. through selection or contest
