    One reaction to all the concern about tropical deforestation（砍伐森林） is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
    The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
    Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks ,disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
    Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
    Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
    Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realize the severe effects of tropical deforestation, it will be 20 years too late.
    Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
    58．The underlined word "synthetics" probably means a kind of _________.
    A．natural rubber   B．tropical material   C．man-made material   D．tropical tree
    59．In the last paragraph the author tries to__________.
    A．tell people how to avoid the tropical deforestation
    B．show us how important it is to protect the tropical forests
    C．persuade people to buy something synthetic
    D．let people realize the effect of tropical deforestation
    60．The author's attitude towards the tropical deforestation is____________.
    A．puzzling        B．cold        C．supporting       D．opposed

    It was starting to get dark and Bobby turned to walk home when suddenly his eyes caught the setting sun’s rays reflecting off something along the roadside. He reached down and discovered a shiny dime(一角钱). Never before has anyone felt so wealthy as Bobby felt at that moment.
    As he held his new found treasure, a warmth spread throughout his entire body and he walked into the first store he saw.
    His excitement quickly turned cold when the salesperson told him that he couldn’t buy anything with only a dime.
    He saw a flower shop and went inside to wait in line. When the shop owner asked if he could help him, Bobby presented the dime and asked if he could buy one flower for his mother’s Christmas gift. The shop owner looked at Bobby and his ten cents offering. Then he said to him, “You just wait here and I’ll see what I can do for you.”
    The sound of the door closed as the last customer left. All alone in the shop, Bobby began to feel cold and afraid. Suddenly the shop owner came out. There, before Bobby’s eyes, lay twelve long stem, red roses, with leaves of green and tiny white flowers all tied together with a big silver bow. Bobby’s heart sank as the owner picked them up and placed them gently into a long white box. “That will be ten cents, young man.” The shop owner said reaching out his hand for the dime.
    Sensing the boy’s reluctance(勉强), the shop owner added, “I just happened to have some roses on sale for ten cents a dozen. Would you like them?”
    When the man placed the long box into his hands, he knew it was true. Walking out of the door that the owner was holding, Bobby heard the shopkeeper say, “Merry Christmas, son.”
    小题1:Bobby feel that he was rich?

    Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep a problem that couldn’t be solved the night before can often appear more manageable, although the evidence（证据）until now has been personal experience. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can improve insight（洞察力）and problem-solving.
    “If you have some newly-got memories in your brain, sleep acts on these memories and rebuild them, so that after sleep the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist（神经病学专家）at the university. To test the theory, they taught volunteers two simple rules to help them turn some numbers into a new order．There was also a third，hidden rule，which could help them increase their speed in solving the problem．The researchers divided the volunteers into two groups：half were allowed to sleep after the training while the rest were forced to stay awake．Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group．“Sleep helped，”Born said in a telephone interview．“The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep，so it can act on the problem．”But Born admitted that he and his team don’t know how rebuilding of memories occurs or what governs it．Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can help develop creative thinking．Although the role of sleep in human creativity will still be a mystery，the research gives people good reason to fully respect their periods of sleep，they added．
    60．The underlined phrase“sleep on it”in Paragraph 1 probably means_________．
    A．to delay deciding something until the next day
    B．to get as much sleep as possible
    C．to go on sleeping without being disturbed
    D．to sleep till after the time you usually get up in the morning
    61．Jan Born and his team carried out the experiment through________．
    A．comparison    B．interview        C．survey          D．imagination
    62．It can be inferred from the passage that___________．
    A．people should sleep so long as they have time
    B．sleep is the only way to solve hard problems
    C．people have various periods of sleep   D．people know how sleep rebuilds memories
    63．What would be the best title for the passage?
    A．How Sleep Works．               B．Sleep Helps Solve Problems．
    C．No Evidence，But Well Founded．   D．Born’s Discovery on Sleep．

    "Depend on yourself" is what nature says to every man. Parents can help you. Teachers can help you. But all these only help you to help yourself.
    There have been many men in history.  But many of them were very poor in childhood, and no uncles, aunts or friends to help them. Schools were few. They could not depend upon them for an education. They saw how it was and set to work with all their strength to know something. They worked their own way till they became well-known.
    One of the most famous teachers in England used to tell his pupils, "I can not make worthy men of you, but I can help make men of yourself."
    Some young men don't try their best to make themselves valuable to the human beings. They can never gain achievement(成就) unless they see their weak points and change their course. They are nothing now, and will be nothing as long as they live, unless they accept the advice of their parents and teachers, and depend on their own efforts.
    64. Which of the following titles fits this article best?
    A. What Nature Says to Every Man.    B. How to Be Famous.
    C. Men Must Help Each Other.        D. Depend on Yourself.

    A. they wanted very much to become well known
    B. they made great efforts to learn and work
    C. they had received a good education
    D. they had rich parents
    66. According to the famous teacher in England, a teacher can________.
    A. make his pupils rich men
    B. help his pupils find a way to be famous
    C. help his pupils make themselves useful men

    A team of scientists proved that seals had a very good sense of hearing. These men trained blind seals to expect food when they heard sounds. The seals always began snapping(猛咬) when a strong signal was sounded.
    It was proved that even a soft signal, a considerable distance away, could make these sea animals respond. That should make the fisherman who makes much noise while working, or talks loudly, start thinking.
    The same team of scientists also trained seals to recognize different sounds. One bell-tone meant food ,two bell-tones meant no food. In the beginning, the seals made mistakes when the two bell-tones were sounded. They were given a light tap after each mistake. The seals were good learners. They easily learned to tell the difference between the sounds.
    67.Why was it necessary to use blind seals? Because they______.
    A. were unable to use sight for clues    B. had better hearing
    C. were waiting to be fed             D. were the only animals to be found
    68. To those seals strong signal meant_____.
    A. snapping     B. nothing      C. food       D. a light tap
    69. The article doesn’t say directly but suggests that fishermen usually think______.
    A. seals have no good sense of hearing   B. seals have good sense of hearing
    C. seals can only recognize bell sounds   D. seals can not hear soft or long distant sounds
    70. Which title will be the best to suit the article?
    A. Clever Seals                      B. Smart Learners 
    C. An Underwater School             D. An Unknown School

    D
    An altimeter(高度计) is an instrument used in an airplane to tell the pilot how high he is flying. The altimeter used in most airplanes is a kind of barometer(气压计), which, like barometer found in ordinary homes, is a measuring instrument for air pressure. The weight of the atmosphere presses downwards everywhere. At sea level this pressure is more than 14 pounds on every square inch of the surface. The higher you go into the air, the lower the air pressure is. An altimeter measures this air pressure to show the altitude of the airplane, or, how high it is above sea level.
    But the altimeter does not show how high the plane is above the ground. A plane might be flying at an altitude of 15,000 feet, but it would be only a thousand feet or so above the ground if the land in that area happened to be 14,000 feet above sea level. The pilot adjusts his altimeter to the actual sea-level pressure before leaving the airport and then corrects it in flight by new information given to him by radio. He flies high enough to be above any mountain he may pass on his course .The barometer altimeter is correct within about 300 feet.
    Another kind of altimeter, the radio altimeter, makes use of radio reflection. It calculates the height of the flying plane by sending out electrical signals to the surface below and measuring the time required for them to bounce back(反弹). It is correct within 15 feet over water, but is not reliable over land. Big planes usually have both kinds of altimeter.
    67. Which of the following diagrams gives the correct relationship between altimeters and barometers? (a----altimeters, b----barometers)

    68. The following drawing shows a plane flying over a mountain. Which of the heights given in the drawing is given by the barometer altimeter in the plane at this moment?

    69. Suppose a plane using a radio altimeter is flying 10,000 meters above highland which is 4,000 meters above sea level. What reading will be given by the altimeter?
    A.10,000meters.   B. 4,000meters.    C.14,000meters.    D. 6,000 meters.
    70. Suppose a plane using both kinds of altimeters is flying over a mountainous area where the land rises and falls very abruptly (迅速地). The pilot keeps his plane steady at the same height. What kind of reading will you get on each of the altimeters?
    A. The readings on both altimeters will remain steady.
    B. The readings on both altimeters will rise and fall abruptly.
    C. The readings on the barometer altimeter will rise and fall abruptly, while that on the radio altimeter will remain steady.
    D. The readings on the radio altimeter will rise and fall abruptly, while that on the barometer altimeter will remain steady.

    Backpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don’t mind carrying a heavy load, your backpack might also power your MP3 player, keep your cell phone running, and maybe even light your way home.
    Scientists from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass., have invented a backpack that makes electricity from energy produced while its wearer walks.
    The backpack’s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer’s back, and the whole pack moves up and down as the person walks. A mechanism with gears(传动装置) collects energy from this motion and transfers it to an electrical generator.
    Surprisingly, the researchers found, people walk differently when they wear the springy packs. As a result, wearers use less energy than when carrying regular backpacks. Also, the way the new packs ride on wearers’ backs makes them more comfortable than standard packs.
    The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. These people often rely on global positioning system(GPS) receivers, night-vision goggles(夜视镜), and other battery-powered devices to get around and do their work. Because the pack can make its own electricity, users don’t need to give up space in their packs to lots of extra batteries.
    For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren’t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!
    65. The passage introduces a new kind of ______ backpack.
    A．electronicB．electricity-producing
    C．electron-generatingD．electricity-controlling
    66. The new backpack makes use of ______ to produce power.
    batteries placed at the bottom of the frame
    the motion of the pack while the wearer walks
    energy the wearer consumes for carrying the pack
    the collective motion of a mechanism and some gears
    67. From the passage, we can infer that ______.
    the backpacks of mountaineers may become smaller in the future
    the new backpack can hardly be produced due to its potential danger
    the new backpack will someday replace MP3 players and cell phones
    the backpack will also provide electricity for lighting our houses
    68. An enormous disadvantage of power-generating backpacks might be that ______.
    they may stop working at any time
    it takes quite a while to have the energy transferred
    they may distract the wearer’s attention from road safety
    they will be extremely heavy with the mechanism

    Everyone has heard of the San Andreas fault (断层), which constantly threatens California and the West Coast with earthquakes. But how many people know about the equally serious New Madrid fault in Missouri?
    Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe. Buildings in the area were almost destroyed. Whole forests fell at once, and huge cracks opened in the ground, allowing smell of sulfur （硫磺）to filter upward.
    The Mississippi River itself completely changed character, developing sudden rapids and whirlpools. Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Madrid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earthquakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington, D.C.
    Scientists now know that America’s two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the movement of these two masses suddenly lurches (倾斜) forward.
    The New Madrid fault, on the other hand, is a vertical fault; a some point, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now, the rock continues to settle downwards, and sudden sinking motions trigger (触发) earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern lllinois.
    Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the area since 1811; these smaller quakes indicate that larger ones are probably coming, but the scientists say have no method of predicting when a large earthquake will occur.
    72. This passage is mainly about__________.
    A. the New Madrid fault in Missouri
    B. the San Andreas and the New Madrid faults
    C. the causes of faults
    D. current scientific knowledge about faults
    73. The New Madrid fault is__________.
    A. a horizontal fault            
    B. a vertical fault
    C. a more serious fault than the San Andreas fault
    D. responsible for forming the Mississippi River
    74. We may conclude from the passage that__________.
    A. it is probably as dangerous to live in Missouri as in California
    B. the New Madrid fault will eventually develop a mountain range in Missouri
    C. California will become an island in future
    D. A big earthquake will occur to California soon
    75. This passage implies that__________.
    A. horizontal faults are more dangerous than vertical faults.
    B. Vertical faults are more dangerous than horizontal faults
    C. Earthquakes occur only around fault areas
    D. California will break into pieces by an eventual earthquake
