22、re semi-aquatic apes. They spent much time in water that they lost their body hair, which makes swimming difficult. Daedalus points out that in fact, water is a deadly environment for human beings not by drowning, but by chilling. Our alleged aquatic ancestors should have grown even thicker, longer

23、fur to minimize heat transfer. Indeed, in a maritime accident, it is worth putting on all the clothes you can find; you will live that much longer in the water. As for swimming forget it. It stirs away all the body heat it generates.Sadly, many sea disasters happen so suddenly that there is no time

24、to look for spare clothes. So Daedalus is devising a nautical uniform which reacts with water to form an ideal survival garment. His first inspiration was the absorptive acrylate polymer used in bandages and babies nappy. It can take up hundreds of times its weight of water, expanding into soft jell

25、y-like stuff as it does so. In fibrous form, it can be woven into cloth. Underclothes of this fabric would swell in water into a splendid wet-suit to prevent heatlosing. But Daedaluss suit will not merely insulate; it will actively generate heat. He recalls the immersion batteries on aircraft life-j

26、ackets, which use sea water to generate electricity, and power a signal lamp. His new garment will be one large distributed battery, triggered by immersion in water.Its electrochemistry is an interesting challenge. At first Daedalus wanted it to generate hydrogen perhaps enough of it to fill a ballo

27、on and lift the wearer out of the water. But more sanely, he now wants it .to exploit the high energy for metal oxidation. A distributed zinc-air battery, exploiting the oxygen dissolved in the water, seems best. A few hundred grams of zinc could keep the wearer warm for hours in the coldest water.

28、Hydrogen generated in a side reaction might usefully inflate floating pockets in the garment.Swollen by gas and absorbed water, the survival suit will usefully discourage at tempts to swim. Its wearer may generate a little added heat by shivering, though this also will stir away all the body heat. O

29、nly young babies can combat cold by passive thermogenesis. Advocates of our aquatic origins are welcome to the uninteresting argument that their ability is a very small remnant of our ancestral watery metabolism.（分数：5.00）(1).From the passage we learn that man dies in sea disasters mainly because（分数：

31、acket.D.to use passive thermogenesis.(3).Daedaluss survival water garment can（分数：1.00）A.generate heat.B.generate gas and heat.C.help the wearer swim and keep warm.D.help the wearer float.(4).We can infer from the passage that（分数：1.00）A.with less sea accidents fewer people will die.B.Daedalus s new d

32、esign of water garment costs too much.C.with thicker fat under skin we may survive sea accidents better.D.an aircraft life-jacket can do the same as Daedalus s water garment.(5).The main idea of the passage is（分数：1.00）A.baby can stay alive in cold water longer than adults.B.how to keep out the cold

It offers prime conditions for spotting some of the 400 varieties of coral and 900 species

As you wander its wide lawns or bicycling along the sidewalks in the late afternoon, it is easy to imagine the wives of Spanish governors serving hot chocolate to their guests on the terrace of the

37、aptly-named Chocolate House.Less imposing, though just as defiant against the sun and humidity, are the remains of the Casa Gobierno, the Governors Palace, which stand beneath a vast banyan tree. It is, as the taxi drivers readily concede, the perfect place to escape the sun, drink iced tea and refl

45、han had been appreciated. Just as heart disease has its origins in childhood, breast cancer is not just an adult disease. For example, there is a strong link between high-fat diets in the population and high rates of breast cancer, but at best a weak relationship to the amount of fat an individual w

46、oman consumes as an adult. But the effects of fat in a child s diet may explain why Japanese women who emigrate to the United States maintain their low risk of breast cancer, while the risk faced by their American-born daughters and granddaughters approaches that of white American women.Studies sugg

47、ested that breast cancer risk might in part be determined by the kind of diet a woman consumed as a child and even what her mother ate during pregnancy if the diets were high in calories, and especially if they were rich in animal fat.Animal studies have also suggested that a prenatal diet rich in polyunsaturated fats, which include most vegetable oils, can increase the susceptib
