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

C. Hard physical work.

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

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.”

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

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

It’s midnight already, but the lights in Shi Guang’s dormitory are still on. He and three other students are sitting back to back. They’re all wearing earphones and staring at a computer screen, talking to each other only in words like “charge” or “retreat”. Chen Jiasheng, 22, a senior majoring in electrical engineering and automation at Beijing University of Aeronautics & Astronautics, is a gaming team leader. “ Online gaming is not just about gaming, it’s a community in which we communicate with each other using our avatars(化身),” said Chen. For university students like Chen, online gaming has become more than a fashion – it’s part of life and a way of socializing.

A 2012 research report on online gamers in China released by 17173.com, the country’s leading game information portal, supports this concept. According to the report, university students aged between 19 and 25 make up 58 percent of online gamers, and the proportion is rising every year. “Many of my friends spend more time hanging out in online gaming worlds than in reality,” said Wang Jiaming, 21, a junior law major at China University of Political Sciences and Law. “Personally I feel more powerful in virtual worlds than in real life. I’m more confident.”

According to Zhang Quan, 20, a student in the second year economics major at Renmin University of China, one of the distinguishing features of online games compared with offline games is the gaming experience. Offline games test a gamer’s skill at using a keyboard to beat rivals. “Online games are technically more accessible as you don’t have to master these skills,” said Zhang.

But most online games are based on avatars controlled by another human – they are unavoidably more tricky and unpredictable by a computer. “On the surface we are playing games, but actually it’s real people we are dealing with,” added Zhang. “The only difference is that in these games we communicate with each other in different settings, like wars, magic battles and fantasy worlds.”

By engaging in this interactive gaming experience, gamers become team players and promote their social skills. Chen has even made friends by playing in a team with strangers online. “We coordinated our movements and cooperated with each other to win a battle in the cyberspace. The game was virtual but the brotherhood was real. Most of us are good friends in real life,” said Chen.

1.According to the passage, which statement of the following is true?

A. Online gaming is the only world where the young communicate with each other by using their avatars.

B. Online gaming is important to those aged between 19 and 25.

C. Online gaming has a bad effect on health as university students usually stay up playing.

A. some interviews to young people about online gaming.

B. positive effects from online gaming on university students.

C. learning how to co-work with their mates for online gamers

D. the differences between online games and offline ones.

3.The underlined word can be best replaced by ______.

A. competitors B. strangers C. teammates D. partners.

4.Which can be the best title of this passage?

A. Online gaming B. Beyond a virtual reality
