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

"Depend on yourself" is what nature says to every man. Parents can help you. Teachers can help you. But all these only help you to help yourself.
There have been many men in history. But many of them were very poor in childhood, and no uncles, aunts or friends to help them. Schools were few. They could not depend upon them for an education. They saw how it was and set to work with all their strength to know something. They worked their own way till they became well-known.
One of the most famous teachers in England used to tell his pupils, "I can not make worthy men of you, but I can help make men of yourself."
Some young men don't try their best to make themselves valuable to the human beings. They can never gain achievement(成就) unless they see their weak points and change their course. They are nothing now, and will be nothing as long as they live, unless they accept the advice of their parents and teachers, and depend on their own efforts.

Someone asked me, “ what do you think of youth?” I showed him
a can of COKE. See this?
“C” means “courage”. There’s a seed in everyone’s heart. As long as you really keep watering it, it will grow and harvest. Courage gives us the power to follow our dreams. Believe in yourself and be prepared for anything in the future.
“O” stands for “optimism(乐观)”. When in trouble, some
people feel disappointed but some people still keep their dreams. Be sure to choose the latter. Life is very much like a mirror. If you smile on it, it smiles back on you. If you frown, you will get a similar look in return. Throw away the sadness in your hear while filling it with brightness and hope.
“K” can be understood as “knowledge”. In order to keep up with the times, we should use knowledge to enrich ourselves. Knowledge is the food of thought and, as long as it is put in our brain, we will grow wiser.
“E” is short for “enthusiasm(热情)”. Enthusiasm is the sign of youth. We use colorful and paint-brushes in our hands to create the pictures of youth on our own. Let the sky and sea know we’re young. Let our enthusiasm wherever we go.
Drink a can of COKE. You will find your youth as refreshing (有活力的) as a can of coke. Enjoy and value your youth.
1. In the passage, the word “COKE” refers to _______
A. a kind of drink young people enjoy
B. what young people should have
