Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion.

Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, where as if the parents survived they could have another child. In most contemporary(当代的) societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illnesses than young or middle-aged people; unless they have wealth or private or government insurance, they must often “go on welfare” if they have a serious illness.

When older people become senile (衰老的) or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent (疗养的) hospitals have been built. These are often profit making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply “dumping (倒垃圾的) grounds” for the dying in which “care” is given by poorly paid, overworked, and under skilled personnel.

It can be inferred from the passage that in hunting and gathering cultures _______.

A. it was a moral responsibility for the families to keep alive the aged people who could    not work

B. the survival of infants was less important than that of their parents in times of starvation

C. old people were given the task of imparting the cultural wisdom of the tribe to new generations

D. death was celebrated as a time of rejoicing for an individual freed of the hardships of life

According to the passage, which of the following statements about the old people in the United States is true?

A. Many of them live on social security money which is hardly enough.

B. Minority of them remain in a state of near poverty after their retirement.

C. When they reach a certain age, compulsory retirement is necessary and beneficial.

D. With the growing inflation, they must suffer more from unbearable burdens than ever.

The phrase “this need” in paragraph 3 refers to ________.

A. prolonging the dying old people’s lives

B. reducing the problems caused by the retired people

C. making profits through caring for the sick or weak people

D. taking care of the sick or weak people

Which of the following best describes the author’s attitude toward most of the nursing homes and convalescent hospitals?

A. Sympathetic.        B. Approving.         C. Optimistic.        D. Critical.

What do butterfly wings have to do with computer screens? What do birds have to do with high speed trains?

These may sound like strange things to put together. But scientists, inventors, and designers are doing just that. They are learning from nature to create new technology.

The word biomimicry (仿生学) combines two words: biology and mimicry. So people using biomimicry try to use examples in nature to design new technology.

Biomimicry is not a new idea. People have been studying nature for hundreds of years. Leonardo DaVinci used birds as models to invent his flying machine. And when the Wright Brothers made the first successful airplane, they also studied birds. In 998, Janine Benyus, a natural science writer and teacher, wrote a book about biomimicry. To develop her interest in the subject, Janine Benyus started the Biomimicry Institute.

The Biomimicry Institute is a non-profit organization. It brings together scientists, designers, inventors and many other people. It offers classes to teach people biomimicry. It provides money for people to research and test new technologies. And it wants all people, from children to adults, to think about new ways to learn from nature.

People involved with the Biomimicry Institute believe that biomimicry can help solve many of the world’s problems. Often, new technologies can harm nature, but this is not true for biomimicry. Let’s look at some examples.

Butterflies have colorful wings because light shines off them in a special way. Scientists want to copy these same ways to make light shine off computers. They hope this will make for more colorful screens.

Another example of biomimicry is the bullet train. It travels at speeds of over 250 kilometers per hour! But it had a problem: it made too much noise!

Through the observation of birds, scientists thought about a kind of bird, the kingfisher(翠鸟). The kingfisher can dive into water without making any noise because of the shape of its beak(喙). Researchers thought that if they could design the front of the train like this beak, the train would be quieter. Well, it worked!

1.The first paragraph is written to_____.

A.start a discussion                        B.make a brief summary

C.introduce the topic of the text              D.test readers' knowledge on science

2.Why did Janine Benyus set up the Biomimicry Institute?

A.To honor the Wright Brothers.

B.To show her recent inventions.

C.To gather talented people for her research.

D.To explore the link between nature and technologies.

3.We know from the text that the Biomimicry Institute _____.

A.earns a lot by giving classes on biomimicry    B.tells people about their technologies

C.gives free support to scientists             D.teaches children about birds

4.The author gives the two examples at the end of the text to show _______.

A.biomimcry works harmoniously with nature   B.the fast development of modern technology

C.how biomimcry changes our life            D.how nature inspires scientists

5.What’s the main idea of the text?

A.Biomimicry is widely used in the world.

B.People copy nature to create new technologies.

C.The Biomimicry Institute was set up for science.

D.Birds play an important part in new technologies.

 

At the heart of the debate over illegal immigration lies one key question: are immigrants good or bad for the economy? The American public overwhelmingly thinks they’re bad. Yet the agreement among most economists is that immigration, both legal and illegal, provides a small net boost to the economy. Immigrants provide cheap labor, lower the prices of everything from farm produce to new homes, and leave consumers with a little more money in their pockets. So why is there such a discrepancy between the perception of immigrants’ impact on the economy and the reality?

There are a number of familiar theories. Some argue that people are anxious and feel threatened by an inflow of new workers. Others highlight the stress that undocumented immigrants place on public services, like schools, hospitals, and jails. Still others emphasize the role of race, arguing that foreigners add to the nation's fears and insecurities. There’s some truth to all these explanations, but they aren’t quite sufficient.

To get a better understanding of what’s going on, consider the way immigration’s impact is felt. Though its overall effect may be positive, its costs and benefits are distributed unevenly. David Card, an economist at UC Berkeley, notes that the ones who profit most directly from immigrants’ low-cost labor are businesses and employers —meatpacking plants in Nebraska, for instance, these producers’ savings probably translate into lower prices at the grocery store, but how many consumers make that mental connection at the checkout counter? As for the drawbacks of illegal immigration, these, too, are concentrated. Native low-skilled workers suffer most from the competition of foreign labor. According to a study by George Borjas, a Harvard economist, immigration has reduced the wages of American high-school dropouts by 9%. 

Among high-skilled, better-educated employees, however, opposition was strongest in states with both high numbers of immigrants and relatively generous social services. What worried them most, in other words, was the financial burden of immigration. That conclusion was reinforced by another finding: that their opposition appeared to soften when that financial burden decreased, as occurred with welfare reform in the 1990s, which curbed immigrants’ access to certain benefits.

The irony is that for all the overexcited debate, the net effect of immigration is minimal. Even for those most acutely affected — say, low-skilled workers, or California residents — the impact isn’t all that dramatic. “The unpleasant voices have tended to dominate our perceptions,” says Daniel Tichenor, a professor at the University of Oregon. “But when all those factors are put together and the economists calculate the numbers, it ends up being a net positive, but a small one.” Too bad most people don’t realize it. 

1.What can we learn from the first paragraph?

A.Whether immigrants are good or bad for the economy has been puzzling economists.

B.The American economy used to thrive on immigration but now it’s a different story.

C.The agreement among economists is that immigration should not be encouraged.

D.The general public thinks differently from most economists on the impact of immigration.

2.What is the chief concern of native high-skilled, better-educated employees about the inflow of immigrants?

A.It may change the existing social structure.

B.It may pose a threat to their economic status.

C.It may decrease .their financial burden.

D.It may place a great pressure on the state budget.

3.What is the irony about the debate over immigration?

A.Even economists can’t reach an agreement about its impact.

B.Those who are opposed to it turn out to benefit most from it.

C.People are making too big a fuss about something of small impact.

D.There is no essential difference between seemingly opposite opinions.

4.Which of the following might be the best title of the passage?

A.A debate about whether to immigrate.

B.A debate about the impact of illegal immigrants.

C.The great impact of immigrants on the economy.

D.Opposition to illegal immigration.

 

 Henry Edwards Huntington

Henry Edwards Huntington was born in 1850 in Oneonta, New York. In 1872 he went to work for his uncle, one of the owners of the Central Pacific Railroad. Twenty years later, Huntington moved to San Francisco at his uncle’s request to share management of the Southern Pacific Railroad. On the way to San Francisco, he visited San Marino, and later bought it, which is home to his collections today.
   In 1902, Huntington moved his business operations to Los Angeles, where he developed the street railway system that created the structure of the Los Angeles area. He greatly expanded the existing electric railway lines, creating an extensive inter-urban system providing the transportation necessary. Huntington’s business interests continued to grow particularly in the areas of water, power, and land development; at one time he served on as many as 60 corporate boards throughout the United States.
   At the age of 60, he announced his decision to retire in order to devote time to his book and art collections and the landscaping of the 600-acre farm. In 1911 the large Beaux Arts building, in the charge of the architect Myron Hunt, was completed.

In 1913, Huntington married Arabella Duval Huntington. She shared his interests in collecting. As one of the most important art collectors of her generation, she was highly influential in the development of the art collection now shown in the former building.

In 1919, Henry and Arabella Huntington signed the agreement that conveyed their San Marino property and collections to a nonprofit educational trust, creating the Huntington, one of the world’s great cultural, research, and educational centers.  

Henry E. Huntington died in 1927, leaving his great treasures the Huntington, including the world-famous Huntington Library, Art Gallery, and Botanical Gardens in San Marino, California to the public, which hosts more than 500,000 visitors each year.
