1、Fermi ProblemOn a Monday morning in July, the world\'s first atom bomb exploded in the New Mexico desert, Forty seconds later, the shook waves reached the base camp where the Italian-American physicist Enrico Fezmi ａｎｄ　his team stood. After a mental calculation, Fermi announced to his team that the bomb\'s energy had equated 10,000 tons of TNT. The bomb team was impressed, but not surprised. Fermi\'s genius was known throughout the scientific world. In 1938 he had won a Nobel Prize. Four years later he produced the first nuclear chain reaction, leading us into the nuclear age. Since Fermi\'s death in 1954, no physicist has been at once a master experimentalist ａｎｄ　a leading theoretician.Like all virtuosos (大师), Fermi had a distinctive style. He preferred the most direct route to an answer. He was very good at dividing difficult problems into small, manageable bits talent we all can use in our daily lives.To develop this talent in his students, Fermi would suggest a type of question now known as a Fermi problem. Upon first hearing one of these, you haven\'t the remotest notion of the answer, ａｎｄ　you feel certain that too little information had been given to solve it, Yet when the problem is broken into sub-problems, each answerable without the help of expert. s ｏｒbooks, you can come close to the exact solution.Suppose you want to determine Earth\'s circumference without looking it up. Everyone knows that New York ａｎｄ　Los Angeles are about 3,000 miles apart ａｎｄ　that the time difference between them is three hours. Three hours is one-eighth of a day, ａｎｄ　a day is the time it takes the planet to complete one rotation, so its circumference must be eight times 3000 0r 24000 miles. This answer differs from the true value, 24,902. 45 miles, by less than four percent.Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries ａｎｄ　inventions. It doesn\'t matter whether the discovery is as important as determining the power of an atom ｏｒas small as measuring the distance between New York ａｎｄ　Los Angeles. Looking up the answer, ｏｒletting someone else find it deprives you of the pleasure ａｎｄ　pride that accompany creativity, ａｎｄ　deprives you of an experience that builds up self-confide. Thus, approaching personal dilemmas as Fermi problems can become a habit that enriches your life.Fermi\'s team was impressed by Fermi\'s announcement in the base camp because he could even work out the power of the atom bomb in his mind.【单选题】

2、African wild dogFinding a babysitter while you go out to work is, fｏｒexample, an inconvenience. Fｏｒthe African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life ａｎｄ　death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food ａｎｄ　stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution ａｎｄ　unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, ａｎｄ　the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults ａｎｄ　pups, only the dominant male ａｎｄ　female breed. The remaining animals help raise the pups, cooperating to hunt prey ａｎｄ　defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions ａｎｄ　hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey ａｎｄ　to defend the kill. There is also one less stomach in which to carry food back to the den, ａｎｄ　one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups ａｎｄ　still spare a babysitter. But with smaller packs, either the hunting ｏｒthe babysitting suffers, ｏｒthe animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals ｏｒfewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poｏｒreproduction ａｎｄ　low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " ａｎｄ　deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.Steps will be taken to protect the African wild dog.【单选题】

3、Women Staying in Mini-Skirts fｏｒLongerBritish women are happy nowadays to wear mini-skirts up until the age of40, according to research by Debenhams.Just 20 years ago, few women would dare to wear a mini-skirt. after the age of 33, the store said. "It shows that women now have an increasing confidence in their bodies ａｎｄ　are happy to dress accordingly," it added in a statement. "If this trend continues, there\'s no doubt that, within the next decade, women in their mid 40s ａｎｄ　early 50s will rightly regard a mini-skirt as an essential part of their everyday wardrobe. "The figures emerged when the store examined the latest age profile of women buying short,36-cm skirts over the past six months. Their results show that it has jumped from an average age of36-years-old at the start of millennium to 40 today. Figures from 1980 showed that on average women stopped buying minis when they reached 33 years old, a figure unchanged from the mid-1960s.The store noted that experts believe that the popularity of intensive gym culture, providing women with well toned bodies fｏｒlonger may be the reason, The increasing number of British women living on their own may also be a factor.The Debenhams\' study showed that a modern woman\'s love affair with a mini-skirt begins at the age of 14 but that she doesn\'t buy her first one until the age of 16. Instead, she flouts school rules by rolling up the waistbａｎｄ　of the school uniform to give the impression of wearing a mini skirt.Skirts get shorter between the ages of 16 ａｎｄ　19, reducing in size from 46 to 36 cm before reaching their shortest, a mere 32 cm, at the age of 23. Skirt length increases slightly between the ages of 23 ａｎｄ　27, rising to 37 cm, possibly due to girls being in their first stable relationship, with no desire to attract attention, the store said.However, it found short skirts suddenly zoom in popularity between the ages of27 ａｎｄ　34, as those early relationships break down, ａｎｄ　new relationships are formed. The move into longer skirts begins irreversibly at 40 years old, when 46-cm skirts, still slightly above the knee are the norm. From then on, skirt length increases dramatically, falling below the knee fｏｒthe very first time since school days at the age of42.Debenhams could most possibly be ____.【单选题】
