    The eruption of a volcano in the Canary Islands could trigger a “mega-tsunami”（巨大海啸）that would hit Atlantic coastlines with waves as high as 330 feet, scientists said on Wednesday. They said an eruption of the Cumbre Vieja volcano on La Palma, part of the Spanish island chain off West Africa, was likely to cause a massive chunk（大块）of rock to break off, crashing into the sea and kicking up huge walls of water higher than any other in recorded history. The tsunami would be capable of traveling huge distances at up to 500 miles an hour, the scientists said in a research paper to be published soon.
    Simon Day, of the Benfield Greig Hazard Research Centre at the University College of London, said that as the volcano was not erupting at present, the short-term and medium-term risks were “negligible”. But Cumbre Vieja should be monitored closely for any signs of activity so that emergency services could plan an effective response, he said. “Eruptions of Cumbre Vieja occur at intervals of decades to a century or so and there may be a number of eruptions before its collapse（倒塌）,” said Day, who cooperated on the research with Steven Ward of the University of California. “Although the year-to-year probability of a collapse is therefore low, the resulting tsunami would be a major disaster with indirect effects around the world.”
    The effects would spread north, west and south of the Canaries, with the west Sahara bearing the worst of the wave’s energy. The energy released by the collapse would be equal to the electricity consumption of the entire United States in half a year.
    Immediately after the landslide（山崩）,a huge wave of water 93,000 feet high and tens of miles wide would form. As the landslide rocks moved deeper under water, a tsunami would develop. Within 10 minutes, the tsunami would have moved a distance of almost 155 miles. On the west Saharan shore, waves would probably reach heights of 330 feet.
    Florida and the Caribbean, the final north Atlantic destinations to be affected by the tsunami, would have to brace themselves for 165-foot waves some eight to nine hours after the landslide. Wave heights toward Europe would be smaller, but substantial waves would hit the coasts of Britain, Spain Portugal and France. The research paper estimated water would penetrate several miles inland and that the devastation would cause trillions of dollars in damage.
    76. What would be the result of a big chunk rock falling into the sea?
    A. Waves would be very high.                                         B. The volcano would stop.
    C. Walls of water would kick up a storm.                          D. An earthquake would take place.
    77. The word “negligible”(Line 3, Paragraph 2) is closest in meaning to ______.
    A. unimportant                    B. small                              C. predictable               D. avoidable
    78. From the passage we may learn that the volcano erupts ______.
    A. every year                                                                 B. every 5 to 9 years
    C. every 10 to 100 years                                                        D. every 5 to 10 months
    79. All of the following are true EXCEPT ______.
    A future eruption of Cumbre Vieja volcano may experience a massive collapse
    Waves generated by the landslide could even reach the coasts of the United States
    The landslide-released energy is equal to half a year’s electricity consumption in the US
    American scientists have managed to utilize the volcanic energy for civil purposes

    D
    Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
    Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
    The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
    Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
    The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
    Over the past last 100years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
    68. What is mainly talked about in this passage?
    A. The melting of glaciers.                B. Global warming.
    C. The world’s weather.                  D. The earth’s temperature.
    69. What causes global warming according to scientists?
    A. Human activities.                     B. The nature itself.
    C. The earth’s atmosphere.                D. New discoveries
    70. How can greenhouse gases make the globe warm?
    A. They keep heat in the atmosphere   
    B. They let the heat go out into space.
    C. They release heat into the air.       
    D. They can make the other gases warm.
    71. From the passage we can see that global warming will bring about _________.
    A. the pollution in the atmosphere            B. natural disasters
    C. population pollution                     D. the rise of glaciers

    There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration （集中）of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution.
    Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of coal and oil is creating a “greenhouse effect” - raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
    Another view, less widely held, is that increasing particular matter in the atmosphere is preventing sunlight and lowering the earth’s temperature - a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen though one recent government reports that the greenhouse effect is very possible. Perhaps, if we are lucky enough, the two tendencies will offset（抵消）each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people don’t think about the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worth?
    72. As pointed out at the beginning of the passage, people used to think that air pollution ________.
    A. caused widespread damage in the countryside
    B. affected the entire eastern half of the United States
    C. had damaged effect on health
    D. existed only in urban and industrial areas
    73. As to the greenhouse effect, the author ________.
    A. shares the same view with the scientists
    B. is uncertain of its happening
    C. rejects it as being ungrounded
    D. thinks it will destroy the world soon
    74. It can be concluded from the last paragraph that ________.
    A. lowering the world’s temperature only a few degrees would lead major farming areas to disaster
    B. raising the world’s temperature only a few degrees would not do much harm to life on earth
    C. almost no temperature variations have occurred over the past decade
    D. the world’s temperature will remain constant in the years to come
    75. This passage is mainly about ________.
    A. the greenhouse effect
    B. the burning of coal and oil
    C. the potential effect of air pollution
    D. the likelihood of a new ice age

    Research on the human brain has been attracting more and more scientists in recent years, just like the booming hi-tech industry. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i.e. to transplant a chip into a human brain. This idea may make everyone’s dream come true. If we compare a human brain to a hard disc（硬盘）, what the scientists are doing is to enlarge the capacity of the hard disc. For the time being, there are some difficulties in such transplant experiments, but scientists never give up.
    Experiments have started on animals. In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U.S. turned a bear into a dolphin.
    The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology available, deep and detailed images were made of the memory area in Ted’s brain containing information about swimming by the scientists. They obtained a series of useful information, the signals transferred by the nervous system. Such information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin’s brain. The information saved on the chip was released by means of electric power.
    Recently, another comprehensive memory transplant was performed at the Motor Nerve Research Institute of the University of California. The comprehensive memory transplanted in the experiment included actions, moods, logic, words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.
    The transplant was performed making a transfer from a dog named “Genius” to a dog named “Idiot”. “Genius” could understand and follow up to 100 gestures and orders made by its master. It was a real genius in memorizing. “Idiot” was the younger brother of “Genius”. It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory.
    The operation was a complete success. When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master. But “Genius” gave no response to its master, and in fact did not recognize him at all.
    57. The purpose of the experiment is _____.
    A. to combine the computer and the human brain    
    B. to enlarge the capacity of human brain
    C. to make some stupid dog turn clever          D. to make bear swim
    58. Which of the following statements is TRUE?
    A. The scientists transferred a button-sized chip with useful information in Tallin’s brain.
    B. The first comprehensive memory transplant was performed at the Motor Nerve Research University.
    C. The second experiment wasn’t an entire transplant of the memory area.
    D. The Idiot was an animal with memory before brain experiment
    59. What does the underlined word “success” refer to?
    A. The two dogs woke up.
    B. They were both good at memorizing.
    C. The Idiot grasped all the abilities of Genius.
    D. The Genius grasped all the abilities of Idiot.
    60. According to the text, we can infer _____.
    A. a person can know more after the experiment
    B. a bear can swim after being transferred a chip with related useful information
    C. a dog can become clever after entire transplant of the memory area
    D. it is really good for animals to have been involved in the transplant experiment

    Many do-it-yourself homeowners are interested in
    trying out solar power to leam about the technology and
    perhaps to provide energy for limited-use applications．
    There are a variety of ways to find cheap solar panels
    （板）, including buying used and building your own
    with factory seconds．Both methods will save money
    while forcing you to learn the ins-and-outs of a solar
    power array （阵列）．  
    We've all seen solar-powered street signs or PV
    panels being used for various purposes at remote locations．
    When those units become cracked or chipped and are considered "unsafe", companies are forced to replace them, generally to avoid responsibility issues．Because it's difficult to get rid of PV panels, many companies, if approached, are willing to give them away or to sell them for modest prices．Depending on the degree of damage present, expect to see performance degradation （降级） in the range of 10% to 60%．A multimeter （万用表） can be used to test the panel before buying．If the panel's free, take it anyway．It could still be useful in a home solar project．
    A solar panel is really nothing but a box serving as a container for a large group of solar cells．Factory second solar cells are usually sold on eBay at a small part of their regular cost．The cells come in a variety of sizes．You will need to figure out how much power a single cell produces to determine how many will need to be wired together to form an array．
    A simple search of the Internet will show numerous sites detailing home solar panel projects．Do-it-yourself lovers are generally quite generous in supply photographs of their work and description of what went wrong and right with the project．
    Getting cheap solar panels with slight imperfections, either used or through sales of factory seconds, is a perfect solution for home-built renewable energy projects．The high number of solar lovers online provide a wealth of useful information．Only limited skills are required, plus an understanding of the basic wiring involved．All are well within the talents of almost any home handyman．Beyond the satisfaction of having completed the project, you'll come away with a functional solar panel that will be a source of power for use around the house or at remote locations．
    Solar energy systems are quickly becoming more popular with homeowners as prices continue to decline．
    72．The author writes the passage to introduce ____．
    A．ways of finding cheap solar panels B．ways of saving energy

    Can you imagine a catfish bigger than a boy? There are more than 1，000 kinds of catfish；28 species are found in the United States' lakes and rivers． This huge family has some mighty strange members. Let's meet a few.
    Walking catfish．Nature's feisty little catfish，found in southern Florida，has an extra lung for breathing on dry land. When its swimming hole dries up，the walking catfish waddles on stiff forward fins in search of another lake or stream．If an enemy attacks，the fish flares（展开）its top and front fins and leaps at the attacker to scare it off．
    Armored catfish．This catfish has heavy，bony plates protecting its body. The shell makes the fish difficult to bone. To cook it，throw the fish whole into a fire. When it is done，break it open for eating．Some armored catfish are found in Florida，but the 100-pounders live in South America．
    Rounding out the family of strange catfish are talking catfish，which make growing sound when you pull them from the water；climbing catfish，which move quickly up shore brush in search of food；electric catfish，which can deliver a mild shock；and blind catfish，which settle in the inky blackness of underwater caves．Blind catfish find food through taste buds in their eight whiskers（须）．
    Most catfish have four whiskers on the upper jaw and four on the lower jaw. Sensory holes on these whiskers help the fish smell and taste food even in the muddiest of water．The United States does not have catfish anywhere near the size of those in South America．But in some large U.S，rivers，blue and flathead catties do top 100 pounds．
    Most of the catfish you are likely to catch will be much smaller，about frying pan size．When you catch one，remember that the top fins and the forward fins have poison glands（腺）at their bases. They can give you painful wounds （…）
    63．The purpose of the passage is to___________．
    A．encourage readers to go fishing for catfish
    B．inform readers of the world's largest catfish
    C．describe the unusual characteristics of catfish
    D．explain different ways to catch a variety of catfish
    64．The author talks about the way of cooking an armored catfish to show that
    A．it has heavy and bony plates        B．it's hard to cook and eat
    C．it has too many bones      D．it's poisonous inside
    65．Which is NOT mentioned about catfish in the passage?
    A．Its eating habits．                                    B．Its living conditions． 
    C．Its whiskers．                                 D．Its size
    66．What may be continued in the last paragraph?

    C
    A long-awaited final report from the Food and Drug Administration (FDA) concludes that foods from healthy cloned animals and their offspring(后代) are as safe as those from ordinary animals, effectively removing the last US regulatory(监管的) barrier to the marketing of meat and milk from cloned cattle, pigs and goats.
    The 968-page final report, not yet released but obtained by The Washington Post, finds no evidence to support people’s concerns that food from clones may have hidden risks.
    But, recognizing that a majority of consumers are wary of food from clones—and that cloning could damage the good image of American milk and meat—the report includes hundreds of pages of raw(原始的) data so that others can see how it came to its conclusions.
    The report also admits that human health concerns are not the only subject raised by the coming-out of cloned farm animals.
    “Moral, religious and ethical concerns have been raised,” the agency notes in a document accompanying the report. But the report is “exactly a science-based evaluation.” It reports, because the agency is not authorized by law to consider those subjects.
    In practice, it will be years before foods from clones make their way to store shelves in large quantities, in part because the clones themselves are too valuable to kill for meat or milk. Instead, the expensive animals—replicas(复制品) of some of the finest farm animals ever born—will be used firstly as breeding stock to create what supporters say will be a new generation of superior farm animals.
    When food from those animals hits the market, the public may yet have its say. FDA officials have said they do not expect to require food from clones to be labeled as such, but they may allow foods from ordinary animals to be labeled as not from clones.
    64.   What can we infer from the first paragraph?
    A.    FDA has waited for a long time to get this final report.
    B.    Products from cloned animals have been put into the market before.
    C.    People are having the products from cloned animals safely.
    D.    There have been once opposite opinions against cloned products.
    65.   What does the underlined word “wary” mean?
    A. Disappointed.           B. Careful.         C. Fond.                                 D. Proud.
    66.   It will be a few years before foods from clones come into the market, partly because _____.
    A.    people have little knowledge of the cloned animals
    B.    supporters can’t give powerful evidence to support that
    C.    the few cloned animals will first be used to create superior animals
    D.    they are a new generation for the customers and are too valuable for the customers
    67.   What can we conclude from the passage?
    A.    FDA officials encourage people to eat more food from clones.
    B.    FDA officials think the food from clones will sell better than ordinary food.
    C.    People only worry about the health problems when it comes to foods from the clones.
    D.    All the foods will not have detailed labels on them.

    Let’s do some sleep math．You lost two hours of sleep every night last week because of a big project due on Friday．On Saturday and Sunday，you slept in，getting four extra hours．On Monday morning，you were feeling so bright—eyed that you only had one cup of coffee，instead of your usual two．But don’t be cheated by your energy．You’re still carrying around a heavy load of sleepiness，or what experts call “sleep debt”一in this case something like six hours，almost a full night’s sleep．
    Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get．It’s a shortage that grows every time we skim some extra minutes off our nightly sleep．“People get more sleep debt gradually without being noticed，”says William C．Dement，founder of the Stanford University Sleep Clinic．Studies show that such short term sleep lack leads to a foggy brain，worsened vision，and trouble remembering．Long-term effects include obesity(肥胖)，insulin(胰岛素)resistance，and heart disease．A survey by the National Sleep Foundation reports that we’re losing one hour of sleep each night——more than two full weeks of sleep every year．
    The good news is that，like all debt，with some work，sleep debt can be repaid．Adding all extra hour or two of sleep a night is the way to catch up．For the long-term lack of sleep， take it easy for a few months to get back into a natural sleep pattern．
    Go to bed when you are tired，and allow your body to wake you in the morning(no alarm clock allowed)．You may find yourself catatonic(有紧张症的)in the beginning of the recovery cycle：expect to have ten hours shut—eye per night；As the days pass，however，the amount of sleeping time will gradually decrease．
    So earn back that lost sleep and follow the rules of your innate(固有的)sleep needs. You’ll feel better．“When you put away sleep debt,you become a superman,”says Stanford's Dement，talking about the improved mental and physical capabilities that come with being well rested．
    53．If you have short-term sleep lack，you may___________．   
    A．put on weight    B．get heart disease  C．hate eating food   D．have a poor sight
    54．The example of sleep math is used to show______．
    A．in what case you build up a sleep debt
    B．in what way you can make up for lack of sleep
    C．why you are energetic even without enough sleep
    D．why you need six hours’sleep every night
    55．By saying the underlined sentence，Dement means that______．
    A．you need a lot of sleep to be a superman
    B．you will be in a good state with enough sleep
    C．you need to be a superman to repay sleep debt   
    D．you will become a superman with more sleep debt
    56．What might be the most suitable title for the passage?   
    A．How can you keep energetic?    B．What is sleep debt?
    C．Can you catch up on lost sleep?  D．Can coffee refresh you?
