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 spotted hyena is on the verge of extinction.【单选题】

2、G8 SummitLeaders of theｇｒｏｕｐof Eight MajｏｒIndustrialized Nations (G8) will meet in Scotlａｎｄ　in July this year. Representatives from China, India, Mexico, South Africa ａｎｄ　Brazil have also been invited. Here\'s what the G8 leaders want from the meeting.British Prime Minister Tony Blair wants the G8 to cancel debt to the world\'s poorest countries. He wants them to double aid to Africa to 50 billion pounds by 2010. He has also proposed reducing subsidies to Western farmers ａｎｄ　removing restrictions on African exports. This has not got the approval of all members because it will hurt their agricultural interests. On climate change, Blair wants concerted (共同的) action by reducing carbon emissions (排放). US President George W. Bush agrees to give help to Africa. But he says he doesn\'t like the idea of increasing aid to countries as it will increase corruption. Bush said he would not sign an agreement to cut greenhouse gas emissions at the summit, according to media. The US is the only G8 member not to have signed the Kyoto Protocol(《京都议定书》). Although the US is the world\'s biggest polluter, Bush so far refuses to believe there is sufficient scientific data to establish beyond a doubt that there is a problem.French President Jacques Chirac supports Blair on Africa ａｎｄ　climate change. He is determined to get the US to sign the climate change deal.German ChancellｏｒGerhard Schroder remains doubtful of Blair\'s Africa proposals. Schroder\'s officials have dismissed the notion that money will solve Africa\'s problems as"old thinking". Berlin says that African states should only receive extra money if they can prove they\'ve solved the corruption problem.Russian President Vladimir Putin was doubtful about the value of more aid to Africa. But he has seen a way to make this work to his advantage. Putin intends to use the aid to Africa as a springboard (跳板) next year to propose aid to the former Soviet Republics of Georgia, Uzbekistan, Tajikistan ａｎｄ　Moldova.Japanese Prime Minister Junichiro Koizumi\'s priorities are a seat on the UN Security Council, fｏｒwhich he will be lobbying (游说) at the summit. ａｎｄ　he\'s concerned about the Democratic People\'s Republic of Korea\'s nuclear weapons programme.Chirac takes a stａｎｄ　similar to Blair’s on Africa ａｎｄ　climate change.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:根据主语Chirac可以确定答案出自第四段。第四段第一句：French President Jacques Chirac supports Blair on Africa ａｎｄ　climate change. （Chirac支持布莱尔对非洲和气候变化的看法及态度。）这与题干所表达的意思是一致的，故正确答案是A。

3、Why Would They Falsely Confess?Why on earth would an innocent person falsely confess to committing a crime? To most people, it just doesn\'t seem logical. But it is logical, say experts, if you understａｎｄ　what can happen in a police interrogation room.Under the right conditions, people\'s minds are susceptible to influence, ａｎｄ　the pressure put on suspects during police grillings is enormous. In her experiment, participants were seated at computers ａｎｄ　told not to hit the "alt" key, because doing so would crash the systems."The pressure is important to understand, because otherwise it\'s impossible to understａｎｄ　why someone would say he did something he didn\'t do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess. "Developmental psychologist Allison Redlich recently conducted a laboratory study to determine how likely people are to confess to things they didn\'t do. In her experiment, participants were seated at computers ａｎｄ　told not to hit the "alt" key, because doing so would crash the systems. The researchers then intentionally crashed the computers ａｎｄ　accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.Redlich\'s findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed. Redlich also found that the younger the participant, the more likely a false confession. Of the 15-to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds. "There\'s no question that young people are more at risk," says Saul Kassin, a psychology professｏｒat Williams College, who has done similar studies with similar results. ______ Both Kassin ａｎｄ　Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-ａｎｄ　still, most participants falsely confessed.Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. "In some ways," says Kassin, "false confession becomes a rational decision. "【单选题】
