1、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.The size of a pack must be big enough fｏｒit to survive.【单选题】

Teams compete against each other in a single elimination tournament that eventually crowns a national champion.Nearly 20 million Americans will become the prisoners of basketball festival madness.The fun comes partly from guessing the winners fｏｒevery game. Friends compete against friends, husbands against wives, ａｎｄ　colleagues against bosses.Big name schools are usually favored to advance into the tournament. But each year there are dark horses from little - known universities.This adds to the madness.

5、A Country\'s Standard of LivingThe "standard of living" of any country means the average person\'s share of the goods ａｎｄ　services the country produces. A country\'s standard of living, therefore, depends first on its capacity to produce wealth. "Wealth" in this sense is not money, fｏｒwe do not live on money but on things that money can buy: "goods such as food ａｎｄ　clothing", ａｎｄ　"services" such as transport ａｎｄ　entertainment.A country\'s capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country\'s natural resources. Some region of the world are well supplied with coal ａｎｄ　minerals, ａｎｄ　have fertile (肥沃的) soil ａｎｄ　a favorable climate, other regions possess none of them.Next to natural resources comes the ability to turn them to use, China is perhaps as rich as the USA in natural resources, but suffered fｏｒmany years from civil ａｎｄ　external wars, Fｏｒthis ａｎｄ　other reasons it was unable to develop her resources. Sound ａｎｄ　stable political conditions, ａｎｄ　freedom from foreign invasions, enable a country to develop its natural resources peacefully ａｎｄ　steadily, to produce more wealth than other country.A country\'s standard of living does not only depend upon the wealth that is produced ａｎｄ　consumed within its own borders, but also upon what is directly produced through international trade. Fｏｒexample, Britain\'s wealth in foodstuffs ａｎｄ　other agricultural ____ would be much less if she had to depend only on those grown at home. Trade makes it possible fｏｒher surplus (剩余的) manufactured goods to be traded abroad fｏｒthe agricultural products which would otherwise be lacking. A country\'s wealth is, therefore, much influenced by its manufacturing capacity, providing that other countries can be found ready to accept its manufactures.【单选题】

A.organizations

B.resources

C.products

D.labors

正确答案:C

答案解析:本题有一定难度，干扰项干扰较大，要认真阅读原文。此处是说如果英国仅依靠国内生产的话，在食品和农产品上的财富就会少得多，此处要使用“产品”的含义，不是使用resources，资源，所以最佳答案是C。
