No one really knows how and why people change as they get older. Also, no theory sufficiently explains all the changes of the aging process. Aging is a complex and varied process that varies in how it affects 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 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.

One day last month after I received my salary, I went shopping with my little son. 21 in the 22 store, I had my pocket 23 and my whole salary was gone with it. I was so angry that I almost lost 24 of myself. What could I do? We were not very rich. The money was really not a small sum for my family. It would 25 our life greatly. How could I tell my wife?
I felt very sad and even 26 for losing the money then I got home. To make up for my 27 mistake, I gathered all my strength to give our house a thorough cleaning and then prepared a wonderful meal and cooked a special dish my wife loved to 28 her.
When she came home, I 29 a smile to 30 her. She was 31 to see the neat house and delicious meal. We sat at the table and began to eat. I told my story 32 . She did not 33 .It was as if she had not heard my words.
“I’ve lost my salary,” I murmured to her again.
“I see,” she did not shout at me as I had 34 . She didn’t lose her 35 . So I was afraid she was trying hard to 36 her anger.
A moment later, my wife was still 37 and seemed to be enjoying her favourite dish. At last I could not keep asking, “I’ve lost the money. Why not shout at me?”She 38 her eyes, looking at me and said, “oh, on the contrary, I’m thinking about how to 39 you. It’s 40 who is to blame.
