1、African wild dog
Finding 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 spotted hyena is on the verge of extinction.

2、Ford
(1)Ford's great strength was the manufacturing process not invention. Long before he started a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891, although it was by no means the first popular automobile, the Model T showed the world just how creative Ford was at combining technology and market.
(2)The company's assembly line alone. threw America's Industrial Revolution into overdrive(高速运转）. Instead of having workers put together the entire car, Ford's friends, who were great toolmakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Ford' s Highland Park plant was humming (嗡嗡作响) along in 1914, the world's first automatic conveyor belt could turn out a car every 93 minutes.
（3）The same year Henry Ford shocked the world with the $5 a day minimum Wage scheme, the greatest contribution he had ever made. The average Wage in the auto industry then was $2. 34 for a9-hour shift. Ford not only doubled that he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn't involve an awful lot of training or education. The Wall Street Journal called the plan "an economic crime" and critics everywhere laughed at Ford.
(4)But as the wage increased later to daily $10, it proved a critical component of Ford's dream to make the automobile accessible to all The critics were too stupid to understand that because Ford had lowered his costs per car, the higher wages didn't matter, except for making it possible for more people to buy cars.

3、Status of Teachers in America
At present, in many American cities especially, many teachers in the public schools say they are underpaid. They point to jobs such as secretary or truck driver, which often pay more to start than that of the teacher. In many other fields, such as law, medicine, computer science, a beginning worker may make more than a teacher who has taught for several year.
Teaching has never been a profession that attracted people interested in high salaries. It is by history a profession that has provided rewards in addition to money, the satisfaction of sharing knowledge, of influencing others, of guiding young people. But in the past several years, there are more difficulties in teaching, for many, than there are rewards.
Unruly students, who would have chosen teaching as their life career in the past, are going into other fields.
Another reason for this change in teacher candidates is the changing status of women in the United States. Until the late 1960s and 1970s, one of the most popular choices for women was teaching. But as other professions, such as law and medicine opened up to women, women stopped pouring into teacher training programs. Thus, a major pool of excellent candidates for the teaching profession dwindled(减少).
Bit by bit government officials and others realized that the status of the teacher had suffered. They talked about change. But change in a vast society like the United States is not easy. People's attitudes have formed over many years, and sometimes change takes many years.
Which of the following can give us a true picture of jobs in the United States?【单选题】

A.People in most professions usually get the same pay at the beginning.

B.A beginning worker in medicine earns less than one in any other field. .

C.A beginning teacher earns as much as a truck driver who has worked for several years.

D.A teacher with several years' teaching experience can't make as much as a new lawyer.

正确答案:D

答案解析:第1段第4句可知，从教多年的教师薪水比不上一个刚工作的律师。因此选D。

4、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, who 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 ____ 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!

5、A Country's Standard of Living
The "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, for we 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 for many years from civil and external wars, For this 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. For example, Britain's wealth in foodstuffs and other agricultural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products ____ 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.
