Question: Article: If you have ever been discouraged because of failure , please read on. Usually, achieving what you set out to do is not the important thing. Let me explain. Two brothers decided to dig a deep hole behind their house. As they were working, a couple of older boys stopped by to watch. "What are you doing?" asked one of the visitors. "We plan to dig a hole all the way through the earth!" one of the brothers answered excitedly. The older boys began to laugh, telling the younger ones that digging a hole all the way through the earth was impossible. After a long silence, one of the diggers picked up a jar full of spiders , worms and a lot of insects. He removed the lid and showed the wonderful contents to the visitors who were laughing at them. Then he said quietly and confidently, "Even if we don't dig all the way through the earth, look what we found along the way!" Their goal was far too difficult, but it made them dig. And that is what a goal is for--to make us move in the direction we have chosen. In other words, it sets us to digging! But not every goal will be fully achieved. Not every job will end successfully. Not every hope will come to pass. Not every love will last. But when you fall short of your aim, perhaps you can say, "Yes, but look at what I found along the way! Look at the wonderful things which have come into my life because I tried to do something!" And I believe it is the joy in the journey, in the end, that truly matters.

Question: Article: People have wondered for a long time how their personalities and behaviors are formed. It's not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive. Social scientists are, of course, extremely interested in these types of question. They want to explain why we possess certain characteristics and exhibit certain behaviors. There are no clear answers yet, but two distinct schools of thought on the matter have developed. As one might expect, the two approaches are very different from each other, and there is a great deal of debate between _ of each theory. The argument is often conveniently referred to as nature vs. nurture. Those who support the "nature" side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors. That our environment has little, if anything, to do with our abilities, characteristics and behavior is central to this theory. Taken to an extreme, this theory maintains that our behavior is predetermined to such a great degree that we are almost completely governed by our instincts . Proponents of the "nurture" theory, or, as they are often called, behaviorists, claim that our environment is more important than our biologically based instincts in determining how we will act. Behaviorists see humans as beings whose behavior is almost completely shaped by their surroundings. Their view of the human being is quite mechanistic; they maintain that, like machines, humans respond to environmental stimuli (something that helps sb./ sth. to develop better and more quickly)as the basis of their behavior. The social and political connections of these two theories are significant. In the United States, for example, blacks often score below whites on standardized intelligent test. This leads some "nature" proponents to conclude that blacks are genetically worse than whites. Behaviorists, in contrast, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result ,they do not develop the same responses that whites do. Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes. That the argument will continue for a long time is certain.
Answer: what makes different stages of intelligence

Answer: The author is mainly concerned about solving the problem _ .

Question: Article: Have you ever suddenly felt that someone you knew was in trouble--and was he? Have you ever dreamed something that came true later? Maybe you have ESP . ESP stands for Extra Sensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away. Here's an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I saw him sitting in the chair!" Just then, a telegram came. The woman's father died of a heart attack. He died sitting in a chair. There are thousands of stories like this one on record. Scientists are studying them to find out what's behind these strange mental messages. Here's another example--one of hundreds of dreams that have come true: A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There's room for one more." The man felt the driver seemed dead, so he ran away. The next day, when the man was getting on a crowded bus, the bus driver said, "There's room for one more." Then the man saw that the driver's face was the same face he had seen in the dream. He wouldn't get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed! Some people say stories like these are _ . Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.
