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.The African wild dog has been endangered.【单选题】

3、Why People Use Pseudonyms (假名字)?You can\'t choose the name you are given at birth, but in many countries you can change it legally when you reach adulthood. Of course, most people never change their names even if they feel unhappy about them. However some people do take this course of action－particularly artists! What makes an artist want to change their name? Sometimes it\'s for purely personal reasons, such as the Nobel Prize winning poet from Chile, Neftalf Reyes. He didn\'t want his father to know he was writing poetry, so he changed his name to Pablo Neruda when he was a young man. At other times the reason may appear strange, take the case of the Portuguese poet Femando Pessoa, ____ wrote under 75 different names. The reason? "When I use a different name, I always write in a different way," he explained. In most cases, however , people change their names for social, historical, political, or cultural reasons. Here are some of the most common: reason. The person\'s real name is just too long and difficult to remember. Let\'s be honest, Madonna Louise Ciccone is not as easy to remember as just plain Madonna. And short names are much easier to remember: William Bradley became Brad Pitt and Edson Arantes do Nascimento became Pele.Sometimes names are changed for marketing purposes. For example, if a name sounds too foreign, it may be changed to something that is more recognizable in a market. So in the film world, Ramon Estsvez adopted the name Martin Sheen. Or maybe the artist\'s real name doesn\'t sound attractive－Chad Everett does sound a lot better than Raymond Cramton.Artists sometimes choose the name of someone they admire. Robert Zimmerman changed his name to Boo Dylan because of his admiration for the Welsh poet, Dylan Thomas.Another reason may be practical: in the past, women found it very difficult to get published. To avoid this situation, they sometimes gave themselves men\'s names, so the English author Mary Ann Evans became George Eliot, and she did get her books published!【单选题】

A.whom

B.who

C.which

D.that

正确答案:B

答案解析:本题难度不大，考点是非限定性定语从句的引导词，因为此处的先行词是the Portuguese poet Femando Pessoa，是人，所以要用修饰人的引导词，而且又做主语，结合选项的信息提示，正确答案是B。

4、The State of Marriage TodayIs there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times, and extramarital (婚外的) affairs will be even more common than now.But what are the reasons for this, and is the picture really so gloomy (明暗的)? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands－as they usually didn\'t have jobs outside the home. But with the rising number of women in well－paying jobs, this is no longer the case, So they don\'t feel that they need to stay in a failing marriage.In answer to the second question, the outlook may not be as pessimistic (悲观的) as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now simply live together and don\'t bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive.So is marriage really an outdated institution? The fact that most people still get married indicates that it isn\'t. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!Which of the following is true about the marriage in the United States today? ____【单选题】

A.Divorce leads to the breakup of the family.

B.More than half of the married couples get divorced.

C.American people marry more than four times.

D.More and more people are getting divorced.

正确答案:D

答案解析:本题有一定难度，干扰项干扰较大，B的干扰最大，但是原文提到的是almost 50% of marriages end in divorce now，所以B项里，more than half，夸大了原意，所以正确答案应该是D。

5、Money or Friendship or Both1. Friends and money don\'t mix. It\'s a dangerous combination since a fight over money is one of the fastest ways to end a friendship. But what if a friend asks you to tend him or her some money? If you don\'t lend your friend the money, you risk losing the friend. If you do lend your friend the money, you risk losing both the friendship and your money.2. We have to face facts, so here are some situations you might run across with your buddies (伙伴) and some helpful tips (忠告) on how to deal with them. Thinking about why this person needs to borrow in the first place. If he is always living beyond his means, it is his fault, not yours. Any Sensible person would not put himself in a position of debt so often. So simply say "no" to this friend. Even if your friend really needs that money for emergency use and you are willing to help him, before you dive into your pocket, follow this reality check: Do you have the extra money? Are you sure you don\'t need it? Are you willing to write off that amount if it\'s not returned? If your answers are negative, do yourself a favor and say "no".3. Let\'s assume you can\'t stand saying "no" to your friend because you don\'t want him living off cat food. What do you do? Write down these details on a sheet of paper before opening up your wallet:Amount of the loan.Date of the loan.Time of repayment.Amount of interest (if any).Lender\'s and borrower\'s signature.This will at least keep the borrower from forgetting the loan so easily, If your friend\'s loan is past due, it\'s important that you ask him－and it\'s actually not rude. The longer you wait, the more you are brood (忧伤), and the more your resentment builds.4. You can send him a friendly reminder via E - mail. Tell him something like "I\'m going over my bank account and I\'m just wondering when we\'ll be able to settle that money thing." E - mail saves you from an uncomfortable face - to - face confrontation. There is almost no chance of turning a bad reaction into an argument. Unlike a public conversation, an E - mail message will always be private.5. After asking two or three times, you might have to write it off. That\'s what happens. If he just doesn\'t have the money or is unwilling, then what kind of friend is that?Before you lend money to your friend ____.【单选题】

A.you can remind your friend of it via E - mail

B.you can lend more money to him or her

C.you must get to know why he or she needs that money

D.if you should lend money to your friend

E.you can call the police to settle the issue

F.there is no need to maintain a friendly relation with him or her

正确答案:C

答案解析:本题难度不大，答案依据不难找到。答案依据在第二段。读懂题干意思后，认真阅读第二段。第二段第二句话，Think about why this person needs to borrow in the first place，是主要依据，再回来看选项，C项符合文章句意，是答案。
