In the Caucasus (高加索) region of Russia, nearly 50 out of Wap版

试题详情及答案解析

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 theirisolation. 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.

试题分析：在俄罗斯的高加索山脉，近日有将近50位老人庆祝百岁生日，还有人不仅仅是100岁而已。而在全美国百岁老人也才不过3人。不仅是高加索山，在厄瓜多尔也有相似的 “长寿村”。这些老人长寿有什么秘密吗？
【小题1】细节理解题。根据“First of all, hard physical work is a way of life for all of these long-living people.”可知，他们长寿的第一个原因是艰苦的体力劳动。这对夫妇是用来证明此例的。故选B。
【小题2】细节理解题。根据First of all, hard physical work is a way of life for all of these long-living people. 可知，他们长寿的第一个原因是艰苦的体力劳动。他们一生都没有脱离劳动。故选C。
【小题3】细节理解题。由“To a great extent (程度), they are separated from the pressures and worries of industrial society.”

可知，长寿村的人们的隔离使他们远离了现代社会的压力和焦虑，因此可见压力和焦虑是有害于人们健康的一项因素。故选D。

【小题4】词义猜测题。另外一个有关于他们健康的原因是他们的与世隔离。由于他们远离了现代的健康负面因素，因此更能获得健康快乐。因此

isolation可以表示“分离的状态”。故选A。

【小题5】主旨大意题。文章主要是介绍了长寿的一些人们，并着重分析了他们为什么会那么会长寿的原因。故选C。
