Alzheimer's disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer's disease. It is a leading cause of death among the elderly. But Alzheimer's disease is not confined(限于) to the aged. There may be a million or more people under the age of 65 suffering from the disease.
At one time, people suffering from the disease were said to be "getting old". The disease was thought to be a natural part of growing old, but it is now known that Alzheimer's disease strikes young and old alike. It is an organic(器官的) disease that destroys brain cells.
Alzheimer's disease affects the patient's memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking. Then the patient's memory begins to fail. He may forget dates, telephone numbers, names and plans.
As the disease progresses, the patient may not recognize family and friends. These symptoms(症状) often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.
In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.
Scientists don't know exactly what causes Alzheimer's disease. It may be caused by a virus(病毒). It may be caused by a poisonous substance(物质) in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.

阅读下列短文，从每题材所给的四个选项中选出最佳选项，并在答题卡上涂黑。
When I was an official of a school in Palo Alto, California, Polly Tyner, the president of our board, wrote a letter that was printed in the Palo Alto Times. Polly’s son, Jim, had great difficulty in school. He was classified as the educationally handicapped and required a great deal of patience on the part of his parents and teachers. But Jim was a happy kid with a great smile that lit up the room. His parents knew his difficulties, but they always tried to help him see his strengths so that he could walk with pride. Shortly after Jim finished high school, he was killed in a motorcycle accident. After his death, his mother submitted this letter to the newspaper.
“Today we buried our 20-year-old son. He was killed in a motorcycle accident on Friday night. How I wish I had known that the last time I had talked to him would be the last time. If I had only known that, I would have said to him, ‘Jim, I love you and I’m always so proud of you.’ I would have taken the time to count the many blessings he had brought to the lives of the people who loved him. I would have taken the time to appreciate his beautiful smile, his laughter, and his genuine love to other people.
“When I put all the good things on the scale and try to balance them with all the irritating (恼人的) things such as the radio that was always too loud, the haircut that wasn’t to our liking, the dirty socks under the bed, etc, I find that the irritations really don’t amount to much.
“I won’t get another chance to tell my son all that I would have wanted him to hear, but, other parents, do have a chance. Tell your young people what you would want them to hear as if it may be your last conversation. The last time I talked to Jim was the morning of the day when he died. He called me to say, ‘Hi, Mom! I just called to say I love you. You have to go to work now. Bye.’ That day, he gave me something to treasure forever. ”
If there is any purpose at all for Jim’s death, maybe it is to make others appreciate life more and to tell people, especially family members, that they should take the time to let each other know just how much they care. You may never have another chance. Do it today!

Thirty years ago, when the movie version of my novel Jaw was published, few people including me knew very much about great white sharks．For hundreds of generations, we humans have been taught to fear and hate sharks, and the movie touched a nerve of horror．
Now something long thought impossible has happened．A great white shark was successfully held in capacity for several months．In August last year a very young female great white shark was caught accidentally in a fisherman’s net off Huntington Beach, California, and then kept in an ocean pen（栏栅）for 25 days．After being moved to the Monterey Bay Aquarium （水族馆）, she grew well in the million-gallon Outer Bay Exhibit．She was so lovely that people all liked her very much．Perhaps she was too young to understand that the big tank was not her natural environment, because she didn’t hit her head against the walls in an attempt to swim away as others of her kind have done．And she began to feed almost immediately on small fish offered to her on a pole．In the months that followed, the shark suffered no serious injuries, caught no diseases, and grew noticeably larger, breaking all records for great white sharks in capacity．The longest that any other great white shark had been held was 16 days．
Until February 23, that is, when she hit and killed a soupfin shark（翅鲨）, as she grew bigger and her behavior grew more aggressive, officials at the Aquarium knew the time had come．On March 31, after 198 days in the aquarium, the great white shark was released into the Pacific．
Scientists still have a lot to learn about sharks, especially great white sharks which are now considered to be in danger．Scientists do know that sharks are necessary to ocean health．Remove any significant animal from the sea food chain and you will risk destroying the balance of nature．
