The old idea that child prodigies (神童) “burn themselves” or “overtax their brains” in the early years, therefore, suffer from failure and (at worst) mental illness is just a myth. As a matter of fact, the outstanding thing that happens to bright children is that they are very likely to grow into bright adults.
To find this out, 1,500 gifted persons were followed up to their thirty-fifth years with these results:
On adult intelligence tests, they scored as high as they did as children. They were, as a group, in good health, physically and mentally. Eighty-four percent of their group were married and seemed content with their life.
About 70 percent had graduated from colleges, though only 30 percent had graduated with honors. A few had even flunked out (退学), but nearly half of these had returned to graduate.
Of the men, 80 percent were in one of the professions or in business, managerial or semiprofessional jobs. The women who had remained single had offices, business, or professional occupations.
The group had published 90 books and 1,500 articles in scientific, scholarly, and literary magazines and had collected more than 100 patents.
In a material way they didn’t do badly either. Average income was considerably higher among the gifted people, especially the men, than for the country as a whole, despite their comparative youth when last surveyed.
In fact, far from being strange, maladjusted (难以适应) people locked in an ivory tower, most of the gifted were turning their early promises into practical reality.
The main idea of the passage is __________.
A. that gifted adults can be as intelligent as when they were young
B. that bright children are unlikely to be physically and mentally healthy
C. that gifted children are most likely to become bright grown-ups
D. that when the bright children grow up, they become ordinary
From the passage, we can conclude that ____________.
A. most of the gifted children became white-collar workers
B. half of the gifted followed up graduated from colleges
C. each of the talented published at least one article
D. successful men got higher income than successful women
Which of the following is mentioned in the passage?
A. The gifted could not be fit for their social positions.
B. Most of the bright and successful women remained single.
C. The gifted men got full marks on intelligence tests.
D. Most of the gifted appeared satisfied with their life.
The explanation of the underlined part “turning their early promises into practical reality” is _____________.
A. earning their living and keeping promises
B. doing practical jobs and facing reality
C. doing what they have promised
D. realizing what they were expected

Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.
Though he was tired,Howe slept badly.He turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practical sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Bronte also drew in her dreams in writing ?Jane Eyre.?
To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious(无意识的),but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious part acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called “secret messages to ourselves ”.
According to the passage,Elias Howe was_________.
A.the first person we know of who solved problems in his sleep
B.much more hard-working than other inventors
C.the first person to design a sewing machine that really worked
D.the only person at the time who knew the value of dreams
The problem Howe was trying to solve was_________.
A.what kind of thread to use
B.how to design a needle which would not break
C.where to put the needle
D.how to prevent the thread from getting caught around the needle
Thomas Edison is spoken of because_________.
A.he also tried to invent a sewing machine
B.he got some of his ideas from dreams
C.he was one of Howe's best friends
D.he also had difficulty in falling asleep
Dreams are sometimes called “secret messages to ourselves” because _________.
A.strange images are used to communicate ideas
B.images which have no meaning are used
C.we can never understand the real meaning
D.only specially trained people can understand them
