No one really knows how and why people change as they get older. Also, no theory sufficiently(足够细心地) explains all the changes of the aging process. Aging is a complex and varied process that varies in how it affects(影响) different people and organs. In fact, even in one person , different organ systems “age “ at a different rate.

At a certain point in our lives, our body systems will begin to weaken . It may become more difficult for us to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer , we have always tried to slow or stop this change that leads us toward the end of our lives.

Many factors(因素) decide our health . A good diet plays an important role. The amount and the type of exercise we get are another two factors. Our living condition is yet another. But scientists studying the aging problem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.

There is nothing to be afraid of as the old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often we get better understanding of the world and ourselves.

What we consider the old age now may only be middle-aged some day soon. Who knows ,with so many advances in medical science happening so quickly, life length may one day be measured in centuries ,rather than in years!

  Many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, cannot teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.

It is always more important to know how to study by oneself than to memorize (记住) some facts or a formula (公式). It is usually quite easy to learn a certain fact in history or a formula in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein, Newton and Galileo didn’t get everything from school. But they were all so successful. They invented so many things for mankind. 

Above all, they knew how to use their brains.

1.Whether he is more ________or less, a teacher can’t teach his students everything they want to know.

       A. important       B. useful             C. difficulty        D. knowledgeable

2.A teacher’s job is mainly to train his students to master the ability of __________.

       A. learning by themselves                B. making a living  

       C. reading and thinking                  D. studying all the subjects

3.The reason for scientists’ success is that _______.

       A. they read books that were not taught at school  

       B. they worked all their lives

       C. they wasted not a single moment
