Thousands of sharks are hunted in Asia for special foods, such as shark fin ( 鱼翅 ) soup. And many others get caught in nets, while fishermen are hunting other fish. 49

How to Deal With Problems of Growing Old

Thirty-one million Americans are over 60 years of age, and twenty-nine million of them are healthy, busy, productive citizens. By the year 2030, one in every five people in the United States will be over 60. Elderly people are members of the fastest-growing minority in this country. Many call this the "graying of America"

In 1973, a group called the "Gray Panthers" was organized. This group is made up of young and old citizens. They are trying to deal with the special problems of growing old in America. The Gray Panthers know that many elderly people have health problems: some cannot walk well, others cannot see or hear well. Some have financial problems; prices are going up so fast that the elderly can&39;t afford the food, clothing, and housing they need. Some old people are afraid and have safety problems. Others have emotional problems. Many elderly are lonely because of the death of a husband or a wife. The Gray Panthers know another fact, too. Elderly people want to be as independent as possible. So, the Gray Panthers are looking for ways to solve the special problems of the elderly.

The president of the Gray Panthers is Maggie Kuhn, an active woman in her late 70s. She travels across the United States, educating both young and old about the concerns of elders. One of the problems she talks about is where and how elders live. She says that Americans do not encourage elders to live with younger people. As far as Maggie Kuhn is concerned, only elders who need constant medical care should be in nursing homes.

Maggie Kuhn knows that elders need education, too. She spends lots of time talking to groups of older Americans. She encourages them to continue to live in their own houses if it is possible. She also tells them that it is important to live with younger people and to have children around them. This helps elders to stay young at heart.

Edward de Bone

Lateral thinking ( 迂回思维 ) , first described by Edward de Bone in 1967, is just a few years older than Edward&39;s son. You might imagine that Caspar was raised to be an adventurous thinker, but the de Bone was so famous, Caspar&39;s parents worried that any time he would say something bright at school, his teachers might snap, "Where do you get that idea from ? "

"We had to be careful and not overdo it,” Edward admits. Now Caspar is at Oxford--which once looked unlikely because he is also slightly dyslexic ( 诵读困难 ) . In fact, when he was applying to Oxford, none of his school teachers thought he had a chance. "So then we did several thinking sessions, " his father says, "using my techniques and, when he went up for the exam, he did extremely well." Soon after, Edward de Bone decided to write his latest book, "Teach Your Child How to Think" , in which he transforms the thinking skills he developed for brainstorming businessmen into informal exercises for parents and children to share.

Thinking is traditionally regarded as something executed in a logical sequence, and everybody knows that children aren&39;t very logical. So isn&39;t it an uphill battle, trying to teach them to think ? "You know, " Edward de Bone says, "if you examine people&39;s thinking, it is quite unusual to find faults of logic. But the faults of perception are huge! Often we think ineffectively because we take too limited a view." "Teach Your Child How to Think" offers lessons in perception improvement, of clearly seeing the implications of something you are saying and of exploring the alternatives.

What is TRUE about Caspar ? 查看材料

A.He is Edward"s son.

B.He is an adventurous thinker.

C.He first described lateral thinking.

D.He is often scolded by his teacher.
