Sorry to say, our brains naturally start slowing down at the Cruelty young age of 30. It used to be thought that this couldn"t be helped, but new studies show that people of any age can train their brains to work faster. "Your brain is a learning machine," says University of California scientist Dr. Michael Merzenich. Given the right tools, we can train our brains to act like they did when we were younger. All that"s required is the practice designed just for the purpose: a few exercises for the mind.
Merzenich has developed a computer-based training method to speed up the process(过程)                         in which the brain deals with information (positscience.com). Since much of the data we receive comes through speech, the Brain Fitness Program works with language and hearing to better speed and accuracy (准确性).
Over the course of training, the program starts asking you to distinguish (辨别) sounds (between "dog" and "bog", for example) at an increasingly faster speed. It"s a bit like tennis instructor, says Merzenich, hitting balls at you ~faster and faster to keep you challenged(受到挑战). You may start out slow, but before long you"re pretty quick.
The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic. If you ask your brain to learn, it will learn. And it may even speed up while in the process.
To keep your brain young and plastic you can do one of a million new activities that challenge and excite you: playing table tennis or bridge, doing crossword puzzles, learning a language.... "When it comes to preventing ageing, you really do "use it or lose it" ," says Barbara Sahakian, professor at Cambridge University.

People turn to magic(魔力)chiefly as a form of insurance--that is, they use it along with actions that actually bring results. For example, hunters may use a hunting charm(咒语). But they also use their hunting skills and knowledge of animals. The charm may give hunters the extra confidence they need to hunt even more successfully than they would without it. If they shoot a lot of game(猎物), they credit the charm for their success. Many events happen naturally without magic. Crops grow without it, and sick people get well without it. But if people use magic to bring a good harvest or to cure a patient, they may believe the magic was responsible. 
People also tend to forget magic"s failures and to be impressed by its surface successes. They may consider magic successful if it appears to work only 10 per cent of the time. Even when magic fails, people often explain the failure without doubting the power of the magic. They may say that the magician made a mistake in reciting the spell or that another magician cast a more powerful spell against the magician.
Many anthropologists(人类学家) believe that people have faith in magic because they feel a need to believe in it. People may turn to magic to reduce their fear and uncertainty if they feel they have no control over the outcome of a situation. For example, farmers use knowledge and skill when they plant their fields. But they know that weather, insects, or diseases might ruin the crops. So farmers in some societies may also plant a charm or perform a magic rite to ensure a good harvest.

A．a hunterB．a farmerC．a magicianD．an anthropologist
小题2:Which of the following can best serve as the title of the passage?

How Room Designs Affect Our Work and Feelings
Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical（经验的，实证的） basis. They are discovering how to design spaces that promote creativity, keep people focused and lead to relaxation.
Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room"s ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.
In additions to ceiling height, the view afforded by a building may influence an occupant"s ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention.
Using nature to improve focus of attention ought to pay off  academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.
Recent study on room lighting design suggests than dim（暗淡的） light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.
So far scientists have focused mainly on public buildings. "We have a very limited number of studies, so we"re almost looking at the problem through a straw（吸管）," architect David Allison says. "How do you take answers to very specific questions and make broad, generalized use of them? That"s what we"re all struggling with."
小题1:What does Joan Meyers-Levy focus on in her research?
A．Light.B．Ceilings.C．Windows.D．Furniture.
小题2:The passage tells us that ______.
A．the shape of furniture may affect people"s feelings
B．lower ceilings may help improve students" creativity
C．children in a dim classroom may improve their grades
D．students in rooms with unblocked views may feel relaxed
小题3:The underlined sentence in the last paragraph probably means that ______.
A．the problem is not approached step by step
B．the researches so far have faults in themselves
C．the problem is too difficult for researchers to detect
D．research in this area is not enough to make generalized patterns
小题4:Which of the following shows the organization of the passage?
CP: Central Point    P: Point   SP: Sub-point（次要点）   C: Conclusion

From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us.When humans first 1 , they were like newborn children, unable to use this 2 tool.Yet once language developed, the possibilities for human kinds future 3 and cultural growth increased.
　　Many linguists believe that evolution is 4 for our ability to produce and use language.They 5 that our highly evolved brain provides us 6 an innate language ability not found in lower 7 . Proponents of this innateness theory say that our 8 for language is inborn, but that language itself develops gradually, 9 a function of the growth of the brain during childhood.Therefore there are critical 10 times for language development.
Current 11 of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable. 12 , more and more schools are discovering that foreign languages are best taught in 13 grades.Young children often can learn several languages by being 14 to them, while adults have a much harder time learning another language once the 15 of their first language have become firmly fixed.
16 some aspects of language are undeniably innate, language does not develop automatically in a vacuum.Children who have been 17 from other human beings do not possess language.This demonstrates that 18 with other human beings isnecessary for proper language development.Some linguists believe that this is even more basic to human language 19 than any innate capacities.These theorists view language as imitative, learned behavior. 20 , children learn language from their parents by imitating them.Parents gradually shape their child"s language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.

　　Trees are useful to man in three very important ways: they provide him with wood and other products, they give him shade, and they help to prevent drought and floods.
　　Unfortunately, in many parts of the world man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had.
　　Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.
　　Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by making charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.
　　This does not only mean that the villagers sons and grandsons have fewer trees. The results are even more serious. For where there are trees their roots break the soil up—allowing the rain to sink in and also hold the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.
63. The purpose that the writer wrote this article for is ____ .
　A. to tell people that trees are very useful to man
　B. to warn people not to cut down trees any more
　C. to warn that man mustn"t destroy forests any more
　D. to explain how trees help to prevent drought and floods
64. In the writer"s opinion, ____ , or the forests slowly disappear.
　A. measure must be taken                      B. people shouldn"t draw benefit from the tree
　C. government must realize the serious results      D. unless trees never be cut down
65. According to the article we know it is ____ to prevent the forests from slowly disappearing.
　A. necessary but impossible                    B. necessary but difficult
　C. impossible and unimportant                  D. difficult and impossible
66. In the last two paragraphs the writer wanted to make it clear that ____ .
　A. where there are no trees, the soil becomes hard and poor
　B. where there are many trees, there are fewer floods
　C. where there are no trees, the land might become desert slowly
　D. floods will make the land become desert
