Can a computer think? That depends on what you mean by “think”. If solving a math problem is “thinking”, then a computer can “think” and do so much faster than a man. Of course, most mathematical problems can be solved by repeating certain process over and over again. Even the simple computers of today can do that. It is frequently said that computers solve problems only because they are“programmed” to do so. They can only do what men have them do. One must remember that human beings also can only do what they are “programmed” to do. Our genes “program” us the moment the fertilized ovum(受精卵) is formed, and our possible abilities are limited by that “program”. Our “program” is so much more enormously complex, though, that we might like to define “thinking” in terms of the creativity that goes into writing a great symphony or in developing a brilliant scientific theory. In that sense, computers certainly can’t think and neither can most humans.

Surely, though, if a computer can be made complex enough, it can be as creative as we. If it could be made as complex as a human brain, it could be equal to a human brain and do whatever a human brain can do. To suppose anything else is to suppose that there is more to the human brain than the matter that composes it. The brain is made up of cells in a certain arrangement. If anything else is there, no signs of it have ever been discovered. To duplicate (复制) the material complexity of the brain is therefore to duplicate everything about it.

But how long will it take to build a computer complex enough to duplicate the human brain? Perhaps not as long as some think. Long before we approach a computer as complex as our brain, we will perhaps build a computer that is at least complex enough to design another computer more complex than itself. This more complex computer could design one still more complex and so on and so on. In other words, once we pass a certain critical point, the computers take over and there is a “complexity explosion”. In a very short time thereafter, computers may exist that not only duplicate the human brain but go far beyond it.

1.In what sense does the writer think that humans are programmed?

A. Their characteristics, powers, etc. are fixed before birth.

B. He thinks a man’s abilities are not limited, as a computer’s are.

C. In the sense that humans will always be better than computers.

D. Computers must be operated by men, but man can operate by himself.

2.What does the writer mean by saying that the average human being is unable to ‘think’?

A. It is not true. All humans can ‘think’ in all sense.

B. Human beings fail to think as fast as a computer.

C. Most people don’t have great creative ability.

D. Something has been wrong with his genetic program.

3.What is the ‘critical point’ mentioned in the last paragraph?

A. The point at which a computer is an exact copy of a human brain.

B. When one computer is itself clever enough to design a better one.

C. When a computer can be made as creative as we are.

D. When the computers destroy each other in an explosion.

4.The word ‘explosion’ mentioned in the last paragraph means ________.

A. great damage　　 B. a terrific noise

C. excitement　　 D. big leaps forward

When an NBA player is young he thinks he can win the championship by himself. It is only later when he has aged and been through many battles that he learns an important lesson: there is no “I ” in “team”.

There is no better example of the value of teamwork than the Boston Celtics. Paul Pierce, Ray Allen and Kevin Garnett were all superstars on three different teams. Yet, none of them had any titles to show for it. Then, last season, they decided to sacrifice money and individual statistics to play together. Garnett and Allen joined Pierce on the Celtics and changed the NBA in the process.

It started in simple ways. Garnett and Allen are two of the most intense athletes in the world. They treat every second of every practice like it is the NBA championship. If you want to play alongside them then you will have to do the same. So, the young guys on the Celtics started giving their full effort too.

Pierce had been the star of the Celtics for many years. He used to shoot the ball many times a game. But with the addition of Allen and Garnett he shot less and focused on defense. His selflessness showed the young players that doing what made the team better was the only thing that mattered.

When the Celtics were winning and the game was almost over, Garnett, Pierce and Allen would come out of the game. But they wouldn’t just sit on the bench. Instead, they stood and cheered and screamed for their teammates. They wanted to support their friends and teammates.

Now, the guys who don't play know they can still affect the game by cheering so they scream and cheer when Garnett, Allen and Pierce are playing. The Celtics have developed a strong relationship. They are more than just teammates. They are brothers.

The result: the Boston Celtics won the championship and are considered the favorites to win the Eastern Conference championship again this year.

There is a saying that goes, "A successful team beats with one heart." If that is the case, the Celtics may have the biggest heart in the NBA.
