1、African wild dogFinding a babysitter while you go out to work is, for example, an inconvenience. For the 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 or the babysitting suffers, or the 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 or fewer 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. "Poor reproduction 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、One-Room SchoolsOne-room schools are part of the heritage of the United States, and the mention of them makes people feel a longing for "the way things were." One - room schools are an endangered species (种类), however. For more than a hundred years, one - room schools have been systematically shut down and their students were sent away to centralized schools. As recently as 1930 there were 149,000 one - room schools in the United States. By 1970 there were 1,800. Today, of the nearly 800 remaining one - room schools, more than 350 are in Nebraska. The rest are spread through a few other states that have on their road maps wide - open spaces between towns.Now that there are hardly any left, educators are beginning to think that maybe there is something yet to be learned from one - room schools, something that served the pioneers that might serve as well today. Progressive educators have come up with new names like "peer - group teaching" and "multi - age grouping" for educational procedures that occur naturally in the one - room schools. In a one - room school the children teach each other because the teacher is busy part of the time teaching someone else. The fourth grader can work at the fifth grade level in math and the third grade level in English without the bad name associated with being left back or the pressures of being skipped (超过) ahead. A youngster with a learning disability can find his or her own level without being separated from other pupils. A few hours in a small school that has only one classroom and it becomes clear why so many parents feel that one of the advantages of living in Nebraska is that their children have to go to a one - room school.A major characteristic of the one - room school system is that ____.【单选题】

A.learning is not limited to one grade level

B.pupils mostly study math and English

C.some children have to be left back

D.teachers are always busy

4、Operatunity1. Operatunity is a TV talent show for amateur opera singers, The winners get the chance to sing with the English National Opera. When two housewives, Denise Leigh and Jane Gilchrist won in 2002, their lives changed forever, As they sang Verdi\'s Rigoletto at the Coliseum (音乐厅) in Rome, they were transformed from working mothers into opera celebrities (名人).2. "I live in the village I was born in," says Denise, who is blind. "Lots of my neighbours are family, and my life is all about my three children. Jane, who worked as a cleaner and a shop assistant, was in a similar situation." She says. All I had to look forward to was seeing my four children grow up, and I love them, but ... you know there must be more things than life. Winning Operatunity has opened up avenues I never knew existed."3. "Last year was amazing," Denise continues, "Last month was Paris, before that we were recording at Abbey Road, in London, and recently we had our album launch at the Royal Opera House" "We\'ve been treated like princesses," laughs Jane, "... champagne, chocolates, five - star hotels ..."4. But it wasn\'t all so easy. For Denise, the worst part was waiting at the beginning. "After I\'d sent in my application form I worried for a month, Then I had to wait ten days after my first audition (试唱). That was awful." Even when they won the competition they were allowed to tell their close family but they weren\'t allowed to tell anyone else until later. Denise and Jane also found the travelling is difficult. They couldn’t take their children with them while they were away singing, so they had to organise childcare. However, there\'s been no problem with the physical side of singing: "We didn\'t have to worry about that as we\'ve had lots of help and wonderful voice training." says Jane. They also had to learn to deal with the media." The kids loved the fact that they could stay up and watch us on TV, but I just couldn\'t understand why some newspapers were more interested in the fact I divorced at 21, rather than the fact I had just sung at the Coliseum, says Denise.While traveling, Denise and Jane had to ask someone to ____.【单选题】
