In the Caucasus region（高加索地区）, nearly 50 out of every 100,000 people live to celebrate their 100^th birthday, and many don’t stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Caucasus people aren’t alone. The Pakistani Hunzas, who live high in the Himalaya Mountains, and the Vilcabambans of the Andes Mountains in Ecuador seem to share the secret of long life too.
　　These peoples 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 Caucasus people aged 110-140, 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.” The very youngest estimate was age 60.
　　What accounts for this ability to survive (live) 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-lived peoples. They began their long days of physical labor as children and never seem to stop. For example, Mr. Rustam is 142 years of age. He remembers his life experience: the Crimean War of 1854; the Turkish War of 1878; the Bolshevik Revolution in 1917. His wife is 116 years old. They have been married for 90 years. Mr. Rustam has no plan of retiring from his life as a farmer. “Why? What else would I do?” he asks. Oh, he’s slowed down a bit. Now he might quit (stop working) for the day after 6 hours in the field instead of 10.
　　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 5,000 to 12, 000 feet(1,660 to 4,000meters) 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（因素）that may lead to the good health of these people is their isolation. To a great extent, they are separated from the pressure（压力）and worries of industrial society.
　　Inherited（遗传的） factors also play some role. Most of the longest-lived peoples had parents and grandparents who also reached very old age. Good family genes may, therefore, be one factor in living longer.
　　Finally, although these three groups don’t eat exactly the same foods, their diets are similar. All of them eat little animal meat. Their diets are full of fresh fruits, vegetables, nuts, grains, cheese and milk. They never eat more food than their bodies need.
　　It is clear that isolation from urban pressure and pollution, clean mountain air, daily hard work, moderate diets, good genes, and a youthful approach to life all lead to the health and remarkable long life of all these people.
【小题1】 What is the main idea of this article?

In learning English, one should first pay attention to listening and speaking. It is the groundwork (基础) of reading and writing. You’d better    your best to speak while you do much listening. Don’t be       of making mistakes. But be careful not to let them stop (阻止) you from improving your       . While you are doing this, a good        is to write or keep a diary, write notes or letters. Then if you can, ask some others to go through (浏览)        you have written and tell you where it is wrong. Many mistakes in your speaking will be        found when you write. Through correcting mistakes, you can do better in learning English.
If you are slow in speaking, don’t       about it. One of the helpful ways is reading, either aloud or to yourself. The important thing is to choose       interesting to read. It mustn’t be too difficult for you. When you are reading        this way, don’t stop to       the new words if you can guess their meanings when they have nothing to do with the sentences. You can do that some other time.

Zach Linsky, 11, watches TV for 3 and a half hours a day and plays video games every other day. Zach, a sixth grader in Washington, D. C., is an American. But unlike many kids, he doesn’t have a TV, VCR, or computer in his bedroom. He only has a boom box (手提录音机).

The survey of 3,155 kids, aged 2 to 18, shows that they spend 5 hours and 29 minutes on average(平均的) a day using some types of media outside of school, including 2 hours and 46 minutes watching TV, 21 minutes on the computer, 20 minutes playing video games, and 8 minutes on the Internet. The good news: The total includes 44 minutes spent reading.

The survey also shows that those aged 2 to 7 spend 3 hours and 9 minutes watching TV every day and shows that 32 percent in that age group have TV sets in their rooms. Among those aged 8 to 18, 21 percent have computers in their rooms, 65 percent have TV sets, and 61 percent say their parents don’t stop them from watching TV. Nearly 1 in 4 say they watch more than 5 hours a day.

“Kids are living much more lonely lives than ever before,” says Kay S. Hytnowitz. “They just disappear into their rooms and spend all of their time with these media.”
