When the telephone rings late at night，most women guess it must be one of only four or five people calling. A sister? Maybe. An emergency? Possibly. A mother? Probably not at that time of night. Much more probably it is a close female friend calling to tell you that she is heartbroken because she has split up with her boyfriend again or perhaps simply that a good movie has just started on TV.

At a time when families are spread far and wide and marriages often end in divorce, friendships are becoming more and more important. Erika, a 32-year-old lawyer, is strengthened by her ten year friendship with her married friend Jane. “I was very sick one night, so I called Jane at about 3：00 a．m. to talk about it,” she says. “She was very supportive and even came over to take me to the doctor's.”

As American TV shows like Friends have become more popular, many of us are beginning to see the value of such friendships.TV shows like this tell us that our romantic relationships may not last, but we need to keep in touch with our close friends if we want to survive.

With Erika's family 200 miles away, it is Jane who keeps a spare set of keys to Erika's apartment and waters her plants whenever she is away. “Having Jane around gives me a certain amount of freedom. It is not the kind of thing that you could ask anyone to do, but she knows I would do the same for her.” Jane, who may move to a different city soon, is worried about leaving such a support system of friends. “My friends have more to do with my life than my parents and, therefore, I don't have to spend a lot of time explaining things to them. Friends are more up to date with what is happening.”

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, and then the patient’s memory begins to fail. He may forget dates, 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.

Putting a dinosaur skeleton（骨架）together is not easy. The skeletons are usually very incomplete. Many dinosaur fossils（化石） are discovered badly damaged. Bones are often found crashed (压碎) or bent by the great weight of the dirt and rock above. Sometimes parts from different creatures are mixed together. This just adds to the confusion.

Unfortunately, some scientists have not been careful enough in their descriptions of dinosaurs. They have told grand stories of how dinosaurs looked and behaved. All of these descriptions are based on guesswork – the imaginations of people who have never seen a living dinosaur. Some scientists have made complete pictures of dinosaurs based on just a single bone or tooth or leg. Such pictures are based on many guesses and very little facts. The scientists' ideas often turn out to be wrong when more facts are discovered.

Dinosaur fossils are not found with labels attached showing what the animals looked like. That is why no pictures of dinosaurs are exactly right. Every dinosaur painting is sure to contain at least some wrong information. No artist in the twentieth century ever saw the living, breathing animals -- complete with skin, flesh, and color.

For instance, imagine never having seen or heard of a peacock. One day you find the jumbled bones of it buffed in the ground. You try to put the bones together to form a skeleton. And then you try to draw a picture of what the animal looked like when it was alive. But bones cannot tell the whole story. Even if you are a very good artist, it would be a miracle if you drew a tree picture of a peacock just from the bones and your imagination.
