and many don't stop at 100! In American only 3 people in 100,000 reach 100. But these old people aren't alone.
The people who live high in the Himalaya Mountains and the Andes Mountains, seem to share the secret of long
life, too.
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 work as children and never seem to stop. For example, Mr. Rustam is 142 years of age. He has
experienced several wars. His wife is 116 years old. They have been married for 90 years. Mr. Rustam doesn't
want to stop his work as a farmer. "Why? What else would I do?" He asks. Oh, he has slowed down a bit.
Now he might work for 6 hours in the field instead of 10.
Another factor (因素) that may contribute (有助于) to the good health of these people is their isolation.
Most of them are kept off the modern world. Inherited (遗传的) factors also help. Most of the longest-lived
people had parents and grandparents who also reached very old ages. So good families genes (基因) may be
one factor in living longer.
Finally, although these three groups don't eat exactly the same food, they 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.
B. Hard physical work.
C. Good family genes.
D. The same food.
B. 与世隔绝
C. 独立
D. 淡薄
B. The Old People in the Mountains
C. Long-lived People
D. The Secret of Long Life

High in the mountains, and deep in the forest, lives a lake with many plants and animals in and around her. The plants and animals have enough food and clean water to keep them healthy. The wind carries pure air, and the rain comes down clear and clean.
But recently, Lucy Lake and her friends haven’t been feeling very well. All the plants and animals get together to talk about the problem. “Why are we sick?” “What can we do?” ask all of them. No one has any answers.
Just then two hikers appear. The animals tell them about their problems. “Can you help us?” they ask. “Yes,” one hiker says. “I think it’s because of acid rain.”
“Acid rain comes from chemicals(化学物质) in the air. The pollution comes from factories, cars and trucks.”
“So, although I don’t want to, I help the pollution travel through the air!” says the wind. “And I carry it to the land!” cries the rain.
“If you can help us think of some solutions(解决方法), we will send a message to tell people how to clean up our environment,” one hiker says.
With the help of the plants and animals, the two hikers make a list of ideas for saving Lucy Lake and her friends.
Time passes, and the forest and lake begin to feel a little better.
The next time the hikers climb up the mountains to Lucy Lake, they smile at what they find. “We’re glad things have started to change,” one hiker says. “And we’re glad you helped us make a difference,” says the other.
