Alzheimer's disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it.

Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children.

There are also some physical tests that might show who is at risk of developing Alzheimer's disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients.

Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer's. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke.

The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years.

Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition.

Researchers say they still do not know what causes Alzheimer's disease. But they say these findings might help prevent the disease in the future.

We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons most of them move to find food more easily, but others move to get away from places that are too crowded. When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移)is probably the migration of the fish, which is called “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mice. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.

Recently, scientists have studied the migration of a kind of lobsters(龙虾). Every year, when the season of bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.

A. give birth              B. enjoy warmer weather

B. The migration of the fish called “salmon” is the most famous migration.

C. Living things move from one place to another because they like to travel.

D. Sometimes we know why and how living things move from one place to another, but sometimes we don’t.

It’s that unbelievable fantasy that all of us in the music business are pursuing. While we think that few of us will ever win the “ jackpot”(最高奖赏)of music fame and fortune, emotionally we still hope that one day we will be included in that small group.

   As long as the music business has existed, people have been trying to discover the basic ingredients for success. Opinions range from having post-graduate degrees in composition on the one hand, to having an uncle who drives the bus for Reba McIntype, a famous country music singer, on the other hand. (Probably both would be helpful!) In my opinion, however, there are two doors that are absolutely essential in order to enter credibility. They are available to anyone, but they do require a key, and the key to both of them is perseverance.

There is nothing that can replace excellence! It is the first door we must open in order to have any hope of achieving our musical goals. And, unfortunately, there is no shortcut to excellence. The only way to achieve it is through dedication, discipline and lots of blood, sweat and tears… in other words, perseverance.

Every day I received emails from promising songwriters and musicians all around the world who mistakenly think that natural talent is the magic ingredient for success. While talent is certainly a plus, it is by no means the miraculous elixir(神奇的灵丹妙药)that will turn you into a famous person. Think about it for a moment: How many very talented people do you know personally who are much better songwriters and musicians than those you hear on TV and on the radio? I’ll bet you can say that you know quite a few. And yet, most of these gifted artists will never be known outside their own family or community. Why? Because natural talent—by itself—is not enough.

Next time we will explore the other door to the world of music achievement—the door of credibility—and how the perseverance key works to unlock it as well.

A. talent        B. dedication C. perseverance      D. discipline

69. Which paragraph will end with “Whether you’re very talented, or just average,   perseverance in practicing makes a difference in your music career.”?

A. One    B. Two    C. Three  D. Four

70. What is the author most probably?

A. A psychologist              B. A teacher  C.A well-known musician   D. A talented writer

71. From the passage, the author wants to tell us_________.

A. difficulties in the music business
