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 remaining lions will die out within decades.【单选题】

Employees will suddenly lose their abilities to concentrate.The disease, known as "March Madness", refers to the nearly 65 teams in US men\'s college basketball tournament, it begins on March 15 ａｎｄ　lasts through the beginning of April. 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.

3、New Product Will Save LivesDrinking water that looks clean may still contain bugs, which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Patton, who started Genera five years ago.

4、Desirable Qualities in a TeacherHere I want to try to give you an answer to the question: What personal qualities are desirable in a teacher? Probably no two people would draw up exactly similar lists, but I think the following would be generally accepted.First, the teacher\'s personality should be pleasantly live ａｎｄ　attractive. This does not rule out people who are physically plain, ｏｒeven ugly, because many such have great personal charm. I would say that excludes all of dull ｏｒpurely negative personality. I still stick to what I said in my earlier book: that school children probably suffer more from bores than from brutes.Secondly, it is not merely desirable but essential fｏｒa teacher to have a _____ capacity fｏｒsympathy in the literal meaning of that word; a capacity to tune in to the minds ａｎｄ　feelings of other people, especially, since most teachers are school teachers, to the minds ａｎｄ　feelings of children. Closely related with this is the capacity to be tolerant not indeed, of what is wrong, but of frailty （脆弱) ａｎｄ　immaturity of human nature which induce people, ａｎｄ　again especially children, to make mistakes.Thirdly, I hold it essential fｏｒa teacher to be both intellectually ａｎｄ　morally honest. This does not mean being a plaster saint. It means that he will be aware of his intellectual strengths.【单选题】
