In the Caucasus 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 parison, 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 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 bee 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 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-lived 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 e from mountainous regions. They live and work at elevations 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, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived 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:在俄罗斯的毕加索地区，将近每1000，000人中就有50人能够活到100岁，甚至还不止100岁。而与之相对比，在美国每1000000人中仅有3人能超过百岁，这是什么原因造成的呢？在本文中作者对此种现象进行了分析，提出了长寿的几个方面因素。
【小题1】C推理判断题。在文章第三段开头作者提出问题What accounts for this ability to survive to such old age, and to survive so well？然后指出其中一个原因是First of all, hard physical work is a way of life for all of these long-lived people.随后列举了Mr. and Mrs. Mamedov的例子，由此判断他们的长寿得益于体力劳动。
【小题2】C 细节理解题。根据文章第三段hard physical work is a way of life for all of these long-lived people.可以判断C选项正确。
【小题3】D细节理解题。从文章末段内容可知作者认为高加索地区的人们与外界隔绝，没有来自工业社会的各种压力，这是他们长寿的原因之一，由此判断压力对人的健康和寿命是不利的，故答案选D。
