Question

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 (厄瓜多爾人) 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 (解釋) 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 (遺傳) 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.

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

【解析】

試題分析：在俄羅斯的高加索山脈，近日有將近50位老人慶祝百歲生日，還有人不僅僅是100歲而已。而在全美國百歲老人也才不過3人。不僅是高加索山，在厄瓜多爾也有相似的 “長壽村”。這些老人長壽有什么秘密嗎？

1.“First of all, hard physical work is a way of life for all of these long-living people.”可知，他們長壽的第一個原因是艱苦的體力勞動。這對夫婦是用來證明此例的。故選B。

2.細節(jié)理解題。根據(jù)First of all, hard physical work is a way of life for all of these long-living people. 可知，他們長壽的第一個原因是艱苦的體力勞動。他們一生都沒有脫離勞動。故選C。

3.To a great extent (程度), they are separated from the pressures and worries of industrial society.”可知，長壽村的人們的隔離使他們遠離了現(xiàn)代社會的壓力和焦慮，因此可見壓力和焦慮是有害于人們健康的一項因素。故選D。

4.isolation 可以表示“分離的狀態(tài)”。故選A。

5.。
