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.

It's the end of class. When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their cell phones. They want to log on* to their micro blogs to check the interesting things that have happened in the last hour.

　　Since last year, the trend* of micro blogging has swept the country. Recent surveys shows that most students in middle schools have a micro blog and some even update* their blogs over five times per day.

　　"We learn many fresh and interesting things on micro blogs and they have become popular topics in class," said Andy Liang, 14. "If you do not know about them, you are out of the loop."

　　It is also a great place for students to let out stress. "My parents always ask me to study all the time, and encourage me before exams, but it really adds pressure," said Simon Zhang, 15. "When I share these feelings on my micro blog, I get many replies from friends in the same situation, which makes me feel better."

　　But parents are worried that micro blogging could be a waste of time. Some misleading messages may even cause danger to kids, they said.

　　Mr. Shen, a professor at the China Education Association, suggests parents not worry too much as long as kids are not crazy about micro blogging. Maybe it can become a window for parents to understand their children. "If parents can read their children's micro blogs, they'll know their thoughts, thus leading to better communication and solutions to problems," he said. He also gives some tips for kids.

　　---Don't micro blog for more than one hour a day.

　　---Never micro blog in class.

　　---Try to talk face to face with people from time to time.

　　---Be critical*. Don't trust all the messages on a micro blog.

1.The underlined part "out of the loop" in the passage probably means                 .

　　A. not popular    B. not excited    C. unhealthy        D. unlucky

2.Micro blog made Simon       when he shared his feelings and got replies on his micro biog.

　　A. feel sad       B. let out stress   C. add pressure      D. make friends

3.We can know from Mr. Shen that micro blogging can                  .

　　A. make kids crazy while logging on to it        

 B. bring a lot of misleading messages

　　C. become a window to understand young kids      

D.lead to worse communication

4.Which statement is TRUE according to the passage?

　　A. It's good for kids to micro blog for more than one hour a day.

　　B.Kids should trust all the messages on a micro blog because they are useful.

　　C.The trend of micro blogging has swept the country since five years ago.

　　D. Kids should try to talk face to face with people, not just micro blogging.
