In the Caucasus (高加索) region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don’t stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren’t alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans (厄瓜多尔人) of the Andes Mountains seem to share the secret of long life, too.

These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked “at what age does youth end?” most of these old people had no answer. Several replied, “Well, perhaps at age 80.”

What accounts for (解释) this ability to survive to such old age, and to survive so well? First of all, hard physical work is a way of life for all of these long-living people. They begin their long days of physical labor as children and never seem to stop. For example, Mr. Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. “Why? What else would I do?” he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations (海拔) of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel (血管) system stronger.

Another factor that may contribute to the good health of these people is their isolation. To a great extent (程度), they are separated from the pressures and worries of industrial society. Inherited (遗传) factors also play some role. Most of the longest-living people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.

1. The example of Mr. and Mrs. Mamedov implies that some Caucasians aged 100 to 140 _________.

A. become weak and hopeless

B. benefit from physical work

C. are too old to work in the fields

D. are still working in the fields

2.What is the main way of life for all of these long-lived people?

A. Retiring from their lives as farmers.

B. Having been married for 90 years.

C. Hard physical work.

D. Having no intentions.

3.Which of the following factors is NOT helpful to people’s health and long life?

A. Clean mountain air. B. Daily hard work.

C. Good genes D. Stress and pressure.

4. What does the underlined word “isolation” mean?

A. the state of being separated B. pressure

C. lack of physical labour D. worry

5. What is the main idea of the passage?

A. Russian people live longer than Americans

B. People in the city live longer than those in the country

C. The reason why mountainous people live longer

D. Pressures and worries contribute to long life

Individuality is the particular character, or aggregate (total) of qualities that distinguishes one person or thing from others. Many artists late in the last century were in search of a means to express their individuality. Modern dance was one of the ways some of these people sought to free their creative spirit. At the beginning there was no exacting technique, no foundation from which to build. In later years, trial, error and genius founded the techniques and the principles of the movement. Eventually, innovators (改革者) even drew from what they considered the dread ballet, but first they had to get rid of all that was academic so that the new could be discovered. The beginnings of modern dance were happening before Isadora Duncan, but she was the first person to bring the new dance to general audiences and see it accepted and acclaimed (称赞).

Her search for a natural movement form sent her to nature. She believed movement should be as natural as the swaying of the trees and the rolling waves of the sea, and should be in harmony with the movements of the Earth. Her great contributions are in three areas.

First, she began the expansion of the kinds of movement that could be used in dance. Before Duncan danced, ballet was the only type of dance performed in concert. In the ballet the feet and legs were emphasized, with virtuosity (高超技巧) shown by complex, codified positions and movements. Duncan performed dance by using her body in the freest possible way. Her dance stemmed from her soul and spirit. She was one of the pioneers who broke tradition so others might be able to develop the art.

Her second contribution lies in dance costume. She rejected ballet shoes and stiff costumes. These were replaced with flowing Grecian (希腊式的) tunes, bare feet, and unbound hair. She believed in the natural body being allowed to move freely, and her dress displayed this ideal.

Her third contribution was in the use of music. In her performances she used the symphonies of great masters including Beethoven and Wagner, which was not the usual custom.

She was as exciting and eccentric (怪异) in her personal life as in her dance.

1.According to the passage, what did nature represent to Isadora Duncan?

A．Something to conquer. B．A model for movement.

C．A place to find peace. D．A symbol of disorder.

2.Compared to those of the ballet, Isadora Duncan’s costumes were less _________.

4.We can infer from the passage that the author _________.

A. appreciates modern dance very much

B. dislikes Isadora Duncan’s dance

C. thinks highly of individuality

D. knows a lot about modern arts

5.Which of the following would be the best title for the passage?

A．Artists of the Last Century

B．Evolution of Dance in the 20th Century

London—Sheep, like turkeys and ostriches, are not considered the most clever animals. British scientists said last Wednesday humans may have underestimated the woolly creature. They could be much smarter than we think.

Researchers at the Babraham Institute in Cambridge, southern England, have shown that the animals have a good memory system and are extremely good at recognizing faces—which they think is a sure sign of intelligence.

Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish 25 pairs of sheep faces and used electrodes （电极） to measure their brain activity , which showed they could remember 50 faces for up to two years .

“If they can do that with faces, they have to have reasonable intelligence; otherwise, what is the point of having a system for remembering faces and not remembering anything else?” Kendrick said in an interview.

So hours of seemingly mindless eating grass may not be so mindless after all.

Kendrick believes sheep got their reputation as dumb （unable to speak, unintelligent） animals because they live in large groups and do not appear to have much individuality and are frightened of just about everything.

“All animals, including humans, once they are frightened, don’t tend to show signs of intelligent action,” he explained.

In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain which allows them to distinguish between many different faces which look extremely similar.

“The most important finding （of the study） is that they are able , both from a behavioral point of view and from looking at the way the brain is organized , to remember a large number of individuals for a very long time,” said Kendrick. “It is a very strange system. They are showing similar abilities in many ways to humans.”

1.From the first paragraph we can find that______. .

A．people used to think sheep are smarter than the other animals

B．people used to raise sheep in a wrong way

C．people don’t consider sheep as clever animals

D．people have done a lot of research on sheep

2.From what Kendrick said in the interview we learn that_____. .

A．scientists have learned everything about sheep’s intelligence

B．scientists have learned a little about sheep’s intelligence

C．scientists can’t do anything more about sheep’s memory

D．scientists do not have to research animals’ memory

3.As is known in the passage,__________.

A．sheep are among the week animals

B．it is not right for people to raise sheep in groups

C．when sheep eat grass in the field their minds may be active

D．if people feel frightened, they may become braver
