Passage 21

(南昌市南昌二中高三冲刺模拟考试B篇)

In the Caucasus region of Russia, 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 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 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 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 come 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 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．

　　　　 It is clear that isolation from urban pressures and pollution, clean mountain air, daily hard word, moderate diets, good genes, and a youthful approach to life all contribute to the health and long life of all these people．

　 A. the advertisement　 B. a travel book　 C. a magazine　 D. the diary

Passage 20

(上海市崇明中学2009届高三5月高考模拟考试C篇)

Beyond two or three days, the world’s best weather forecasts are doubtful, and beyond six or seven they are worthless.

The Butterfly Effect is the reason. For small pieces of weather-to a global forecaster, small can mean thunderstorms and blizzards (暴风雪)-any prediction becomes worse rapidly. Errors and uncertainties increase, from dust devils and storms up to continent-size eddies (旋涡) that only satellites can see.

The modern weather models work with net-like points sixty miles apart, and even so, some starting data have to be guessed, since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart, rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature, pressure, humidity (湿度), and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02, then 12.03… the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations (波动) that the computer will not know about. By 12.01, those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale, and so on up to the size of the globe.
