听力原文： 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; (29)it seemed impossible to get the thread to run smoothly around the needle. Though he was tired, Howe so, Howe ran into the salve problem as before. (29)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, hut suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that (30)he bad 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 practiced sewing machine．(31)Elias Howe was not the only one who found 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.

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.

听力原文： One winter day in 1891 a class at a training school in Massachusetts U. S. A. , went into the gym for their daily exercises. Since the football season had ended, most of the young men felt they were in for a boring time. But their teacher, James Nesmith had other ideas. He had been working for a long time on a new game that would have the excitement of American football. Nesmith showed the men a basket he had hung at each end of the gym and explained that they were going to use a round European football. At first everybody tried to throw the ball into the basket no matter where he was standing. "Pass! Pass!" Nesmith kept shouting, blowing his whistle to stop the excited players. Slowly they began to understand what was wanted of them.
The problem with the new game, which was soon called basketball, was getting the ball out of the basket. They used ordinary food baskets with bottoms and the ball of course stayed inside. At first someone had to climb up every time a basket was scored. It was several years before someone came up with the idea of removing the bottom of the basket and letting the ball fall through. There have been many changes in the rules since then and basketball has become one of the world's most popular sports.

A．He took them to watch a basketball game.
B．He trained them to play European football.
C．He let them compete in getting balls out of a basket.
D．He taught them to play an exciting new game.

Professor Arthur Shimamura, of the University of California at Berkeley, says there are three main ways in which mental function changes. The first is mental speed, for example how quickly you can react to fast-moving incidents on the road. Drivers in their late teens react quickly but tend to drive too fast, while the over sixties are more cautious but react more slowly. The near-inevitable slowing with age also partly explains why soccer players are seen as old in their thirties, while golf professionals are still in their prime at that age. This type of mental slowing results from a reduction in the efficiency with which the brain's neurons work.
The fact that adults find it harder to learn musical instruments than children points to a second type of mental loss with age—a reduction in learning capacity. The parts of the brain known as the temporal lobes control new learning, and are particularly vulnerable to the effects of aging. This means that, as we get older, we take longer to learn a new language, are slower to master new routines and technologies at work, and we have to rely more on diaries and other mental aids.
'Working memory' is the third brain system which is vulnerable to the effects of aging. Working memory is the brain's 'blackboard', where we juggle from moment to moment the things we have to keep in mind when solving problems, planning tasks and generally organizing our day-to-day life. Absent-mindedness occurs at all ages because of imperfections in the working memory system—so, for instance, you may continually lose your glasses, or find yourself walking into a room of your house only to find that you cannot remember what you came for.
Such absent-mindedness tends to creep up on us as we age and occurs because our plans and intentions, which are chalked up on the mental blackboard, are easily wiped out by stray thoughts and other distractions. Stress and preoccupation can also cause such absent-mindedness, in addition to age-related changes in the brain. The frontal lobes of the brain—located behind the forehead and above the eyes are where the working memory system is located. Like the temporal lobes, which handle new learning, the frontal lobes are more vulnerable to the aging process than other parts of the brain.
The news, however, is not all bleak. Although neurons reduce in number with age, the remaining neurons send out new and longer connecting fibres(dendrites) to maintain connections and allow us to function reasonably well with only relatively small drops in ability.
This and other evidence suggests that the principle 'use it or lose it' might apply to the aging brain. Professor Shimamura studied a group of university professors who were still intellectually active, and compared their performance on neuropsychological tests with that of others of their age group, as well as with younger people. He found that on several tests of memory, the mentally active professors in their sixties and early Seventies were superior to their contemporaries, and as good as the younger people.
Research on animals provides even stronger evidence of the effects of stimulation on the brain structure. Professor Bryan Kolb, of the University of Lethbridge in Canada, has shown that animals kept in stimulating environments show sprouting(生长) and lengthening of the connecting nerve fibres in their brains, in comparison With animals kept in unstimulating environments.
The beneficial effects of continued mental activity are shown by the fact that older contestants in quiz shows are just as fast and accurate in resp
