Tiger
s are an endangered species(物种). Half of the world’s tiger 41 live in India. For years, tigers have been disappearing from India’s national parks, but Sariska may be the last straw. And the government has to react.On Thursday, Singh held the first meeting of 42 officials, wildlife experts, and related leaders, aiming to count the nation’s remaining tigers, and to come up with a plan to keep them safe.
It is not hard to guess why the tigers are disappearing. Poachers (偷猎者) can 43 the big cats for $50,000 each. Tiger skin and bones are popular in Chinese 44 . A single tiger tooth can fetch $120. Recently, a group of poachers admitted killing ten tigers in Sariska and were 45 .
“Indian tiger poaching is probably the biggest conservation problem in modern times.” said Belinda Wright, the head of the Wildlife Protection Society of India.
However, poaching isn’t the only 46 . Many poachers use advanced technologies, like night glasses and long–range binoculars. Forest security officers are paid so 47 th
at few of them bother to track down the poachers. Even if a security guard were to find a poacher, many carry only a stick to make him obey the law.Tiger fans hope that Singh’s plans mean end for the poachers and 48 for the endangered species.

That"s where the similarities end: this bag can wirelessly keep track of your belongings and remind you, just as you"re about to leave the house, to take your wallet. It can review the weather report and suggest that you take an umbrella. This purse can even upload your favorite songs onto your scarf.
Surely, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. Dupont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty (耐磨损的) cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $ 150, which is the price of an average leather purse.
Here"s how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you"ve forgotten to take your wallet. In turn, sensors on your purse"s handles will notify the computer that you"ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring - and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years - making for a booming market for wearable computers that don"t look like something out of science fiction.
小题1: According to the passage, the new wearable computers _______.
| A．require users to operate on the stomach |
| B．pick up the signals through wires and chips |
| C．are being applied in some different areas now |
| D．are smarter but more expensive than the old ones |
| A．The new wearable computers have become fashionable. |
| B．People would like to learn more about the new computers. |
| C．New wearable computers promise to sell well in the future. |
| D．The idea of the purse-like computers comes from science fiction. |
| A．introduce a new kind of computer |
| B．explain the functions of computers |
| C．compare different types of computers |
| D．show how high technology affects our life |
One common problem gifted kids face is that they, and those around them, place too much importance on being smart. Such an emphasis can encourage a belief that bright people do not have to work hard to do well. Although smart kids may not need to work hard in the lower grades, whe
n the work is easy, they may struggle and perform poorly when the work gets harder because they do not make the effort to learn. If the academic achievement of highly intelligent children remains below average for an extended period, many teachers will fail to recognize their potential. As a result, such students may not get the e
ncouragement they need, further depressing their desire to learn. They may fall far behind in their schoolwork and even develop behavior problems.IQ is just one element among many in the recipe for success—Children develop well or struggle in school for a host of reasons apart from IQ. These include motivation and persistence, social competence, and the support of family, educators and friends.
Because highly gifted children solve the most varied thought problems faster and more thoroughly than those with more average talents do, they need additional intellectual stimulation while they wait for the rest of the kids to learn the basics. Two central approaches are used to satisfy the educational needs of such children: acceleration and enrichment. Acceleration means studying material that is part of the standard subjects for older students. Enrichment involves learning information that falls outside the usual subjects.
A child might skip one or more grades as a way of accelerating in school. But being with older children for the entire school day—and perhaps for grade-based extracurricular activities such as sports—can make a child feel inferior in every filed outside of academics. One very bright fourth-grader who had skipped two grades remained far ahead of his classmates i
ntellectually, but as his classmates reached adolescence, his social and other shortcomings became painfully apparent. While acceleration is not an option, or not a good one, enrichment can be. After all, school is not a race but an adventure in learning. As such, the goal is not finishing first but absorbing as much knowledge as possible in the time assigned. Thus, providing opportunities for a child to study topics outside the regular subjects can be at least as valuable as pushing him or her through the required material faster.小题1:What is the basic reason for the low academic achievement of highly intelligent children?
| A．Teachers’ failure to recognize their potential. |
| B．Too much emphasis on being intelligent. |
| C．Studying topics outside the regular subjects. |
| D．Lack of encouragement from teachers. |
| A．Skipping one of more grades and studying together with older children. |
| B．Learning the same material in the standard subjects for older students. |
C．Learning information that is not included in the regula r subjects. |
| D．Learning how to read with fluency even in their pre-school days. |
| A．He is in favor of enrichment rather than acceleration. |
| B．He is in favor of acceleration rather than enrichment. |
C．He speaks highly of both enrichment and  acceleration. |
| D．He thinks neither enrichment nor acceleration is a good choice. |
| A．point out the weaknesses of acceleration for gifted children |
| B．compare acceleration with enrichment for gifted children |
| C．stress the importance of enrichment for gifted children |
| D．discuss how to bring out gifted children’s potential |
Professor Taiju Matsuzawa wanted to find out
why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and how the speed of getting old could be slowed down.With a team of researchers at Tokyo National University, he set about measuring brain sizes of a thousand people of different ages with different jobs.
Computer technology helped the researchers to get most exact measurements of the sizes of the front and side parts of the brain
, which have something to do with thinking and feeling, and decide the human character. As we all know, the back part of the brain, which controls task like eating and breathing, does not contract(萎缩) with age.Contraction of front and side parts, as cells(细胞) die off, was seen in some people in their thirties, but it was still not found in some sixty and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction---using the head.
The fin
dings show that contraction of the brain begins sooner in people in the country than those in the towns. Those with least possibility, says Matsuzawa, are lawyers, followed by university professors and doctors. White-collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm workers, bus drivers and shop assistants.小题1: The team of doctors wanted to find out ____.
| A．at what point people grow live longer. |
| B．how to make people live longer |
| C．the size of certain people’s brains. |
| D．which group of people are the busiest |
| A．an examination of farmers in northern Japan |
| B．using computer technology |
| C．examining the brain sizes of different people |
| D．tests given a thousand old people |
| A．our brains contract as we grow older |
| B．one part of the brain does not contract |
| C．sixty-year-olds have better brains than thirty-year-olds |
| D．contraction of the brain begins sooner in people in the country |
| A．engineers | B．office clerks | C．professors | D．researchers |
| A．most of us should take more exercise |
| B．it’s better to live in the towns |
| C．the brain contracts if it is not used |
| D．the more one uses his brain, the sooner he becomes old |
Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don"t threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one，the scientists say，we"ll have a way
to change its course.Some scientists favor pushing asteroids off course with nuclear weapo
ns. But the cost wouldn"t be cheap. I
s it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall，it would be the end of the world. “If we don"t take care of these big asteroids，they"ll take care of us,” says one scientist. “It"s that simple.”The cure，though，might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article.
小题1:What does the passage say about asteroids and meteoroids?
| A．They are heavenly bodies different in composition. |
| B．They are heavenly bodies similar in nature. |
C．There are more asteroids th an meteoroids. |
| D．Asteroids are more mysterious than meteoroids. |
| A．It is very unlikely but the danger exists. |
| B．Such a collision might occur once every 25 years. |
| C．Collisions of smaller asteroids with Earth occur more often than expected. |
| D．It"s still too early to say whether such a collision might occur. |
| A．It sounds practical but it may not solve the problem. |
| B．It may create more problems than it might solve. |
| C．It is a waste of money because a collision of asteroids with Earth is very unlikely. |
| D．Further research should be done before it is proved applicable. |
| A．while pushing asteroids off course nuclear weapons would destroy the world |
| B．asteroids racing across the night sky are likely to hit Earth in the near future |
| C．the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime |
| D．workable solutions still have to be found to prevent a collision of asteroids with Earth. |
| A．Optimistic. | B．Critical. | C．Objective. | D．Subjective. |
When you take the Holmes Rahe you must remember that the score does not show how you deal with stress -- it only shows how much you have to deal with. And we now know that the way you deal with these events dramatically affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women’s magazines ran titles like “Stress causes illness.”
If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many -- like the death of loved one--are impossible to avoid. Moreover, any warning to avoid all s
tressful events is a prescription for staying away from chances as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The idea that all stress makes you sick also takes no notice of a lot of what we know about people. It supposes we"re all vulnerable and not active in the face of the difficult situation. But what about human ability and creativity? Many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change
or challenge can lead to boredom and physical and mental pressure.小题1:.
The score of the Holmes Rahe test shows ____ .
| A．how you can deal with life changing events |

| A．popular avoidance of stressful jobs |
| B．great fear over the mental disorder |
| C．a careful research into stress related illnesses |
| D．widespread worry about its harmful effects |
Why is “such simplistic advice ”(Line 2, Para.3) impossible to follow?
| A．No one can stay on the same job for long. |
| B．More effective ways have been found to get rid of stressful events. |
