Large animals that inhabit the desert have evolved a number of adaptations for reducing the effects of extreme heat. (31) adaptation is to be light in color, and to (32) rather than absorb the sun’s rays. Desert mammals also depart from the normal mammalian practice of maintaining a (33) body temperature. (34) trying to keep down the body temperature deep inside the body, (35) would involve the expenditure of water and energy, desert mammals allow their temperatures to rise to what would normally be fever (36) , and temperatures as high as 46 degrees Celsius have been measured in gazelles (瞪羚羊). Another strategy (37) large desert animals is to tolerate the loss of body water to a point (38) would be fatal for non-adapted animals. The camel can lose up to 30 percent of its body weight (39) water without harm to itseff, (40) human beings die after losing only 12 to 13 percent oftheir body weight. An equally important adaptation is the ability to (41) this water loss (42) onedrink. Desert animals can drink prodigious volumes in a short time, and camels have been known to (43) over 100 liters in a few minutes. A very dehydrated person, (44) , cannot drink enoughwater to rehydrate at one (45) , because the human stomach is not sufficiently big and because a toorapid (46) of the body fluids causes death from water intoxication. The (47) of water loss is ofobvious advantage in the desert, as animals do not have to remain (48) a water hole but can obtain food from gazing sparse and far-flung pastures. Desert-adapted mammals have the (49) ability to feednormally when extremely dehydrated; it is a common experience in people that appetite is lost even (50) conditions of moderate thirst.

It seems that our society favors a kind of ritualized aggression. Everywhere you look, in newspapers and on television, issues are presented using the terminology of war and conflict. We hear of battles, duels and disputes. We see things in terms of winners and losers, victors and victims. The problem is society’s unquestioning belief in the advantages of the debate as a way of solving disagreements, even proving fight from wrong. Our brainwashing begins early, at school, when the brightest pupils are co-opted onto the debating team. The training in this adversarial approach continues at our tertiary institutions. The standard way to present an academic paper, for instance, is to take up an opposing argument to something expressed by another academic. The paper must set out to prove the other person wrong. This is not at all the same thing as reading the original paper with an open mind and discovering that you disagree with it. The reverence for the adversarial approach spills over into all areas of life. Instead of answering their critics, politicians learn to sidestep negative comments and turn the point around to an attack on their accusers. Defense lawyers argue the case for their clients even when they suspect they may be guilty. And ordinary people use the same tactics—just listen to your teenager next time you pull him up for coming home late. You can be sure a stream of abuse will flow about your own time-keeping, your irritating habits, and your history of bad parenting. Unfortunately, the smarter your kid, the better his or her argument against you will be. You’ll be upset, sure, but you’ll comfort yourself that those teenage monsters of yours will one day turn into mature, tough adults who can look after themselves—by which you mean, of course, they will be able to argue their way out of sticky situations. It’s not that you should never use angry words, or take up a position in opposition to someone or something. There are certainly times when one should take a stand, and in such cases strong words are quite appropriate: if you witness injustice, for instance, or feel passionately about another’s folly. Mockery—so creel when practiced on the innocent—can be very useful in such situations. There is no better way to bring down a tyrant than to mock him mercilessly. What I dislike is the automatic assumption most people have when it comes to disagreements: they should attack, abuse, and preferably over power their opponent, at whatever the cost. But just think how easy it can be to persuade a "difficult" person to be considerate of you or your wishes when you are pleasant to them, and unthreatening. Give them a way out of a potentially aggressive situation without losing face, and they will oblige you willingly. The author’s tone in this passage can be best described as
Joan of Arc would be proud. Edith Cresson, France’s first woman Prime Minister, has taken office with avow to lead the country into a battle whose outcome will be as fateful as any fought by the Maid of Orleans. "There’s a world economic war going on, and France is not waging it," Cresson warned last year. Now the combative Prime Minister is preparing an offensive to create jobs at home, win markets abroad and keep France in the economic fight. "We are confronted," she says, "with the need to build a balanced Europe, where France is as strong as Germany." Turning to Japan, she warns, "I don’t want hundreds of thousands of jobs to disappear, and to lose our technology and means of wealth." Fighting words at a time when the French, more than ever before, are obsessed with their ability to compete in the global marketplace. Despite illustrations of daring technological progress, such as the TGV and, earlier, the Concorde, "the French really have an industrial inferiority complex," says Paul Goldschmidt, head of Bain ＆ Co., a consulting firm in Paris. Whether that complex is deserved or not, the French see the powerhouse of a united Germany looming large in a Europe destined to become the world’s biggest single market in 1993.Glancing over their shoulders, they look at Italy advancing fast as an economic challenger, its industries quick to exploit market niche. Scanning the horizon, the French are aware of a U.S. reconquering lost export markets even as the Japanese continue their relentless drive for global economic pre-eminence. "We don’t want to end up the Mezzogiorno (意大利南部地区) of Europe," frets Cresson. There is little chance of that happening. The world’s fourth largest economy, with a gross national product of $956 billion, is far from becoming an also-ran. Its companies sell nuclear power plants to Asia, high-speed train systems to the U.S. and Europe, and battle-tested military hardware like the Exocet missile worldwide. French firms are engaged in the gamut of aerospace activity, from missiles for space probes to computerized cockpits for commercial aircraft. They are inventive as well as innovative, patenting, among other things, the radial tire and the hydraulic suspension that makes every Citroen a four-wheeled water bed. They are proud that a Renault-built Formula One car can beat out the seemingly unstoppable Honda-powered McLaren of Ayrton Senna in Grand Prix racing. They are equally pleased that Airbus Industries, the French-led European consortium is giving American companies a run for their money in the competition to sell civilian airlines. Still, Cresson ＆ Co. are right to be concerned. Behind the upbeat economic factors and the prestige of many French products loom some numbers that point to disturbing weaknesses in the economic fabric. French industry is good at many things but maddeningly incapable of deciding where to focus its efforts, thanks to what the daily Liberation describes as a touché-a-tout economy-finger in every pie. Thus there are few areas of real dominance, such as the Germans have in luxury cars and machine tools. According to the passage, the advantages of French economy DON’T lie in the fact that
