    A new power plant in Nakoso, Japan, might someday change everything for coal plants．Since the new power plant fired up in September, the designer, Mistubishi, is expecting to prove it's possible to burn coal without polluting．This technology is known as integrated gasification combined cycle （IGCC）．Proving IGCC works should give Mitsubishi's US partner, NRG Energy, the jump other hurdles to building new clean plants．
    The project promised to solve the problem of the ages for power plants: how to produce cheap, clean, reliable electricity．No existing technology can do all three perfectly．
    The problem is IGCC isn't there yet．It costs about 20 percent more than traditional plants．And even though it's easier to collect the resulting carbon dioxide from an IGCC plant than a traditional plant, there's no proven way to get rid of the greenhouse gas．One plan is to drill a shaft（通道） to pump the carbon dioxide underground, into saltwater formations．But there's no guarantee it will remain underground forever．
    NRG administrators think solving the IGCC riddles is worth the trouble because they expect the U．S．will soon limit the amount of carbon dioxide that power generators may give out ．
    "With the additional cost of IGCC, to just voluntarily build something that's 20 percent more expensive, that’s commercial suicide," NRG chief administrator, David Crane said．
    NRG administrators expect the cost to decline after six or seven plants are built．But other industry experts think it will take about a dozen plants for the price to be competitive with traditional coal plants．
    Takaya Watanabe, a vice general manager of Mitsubishi, admits that the cost challenges are difficult．“It’s good for a company to say we want to be green, but unless someone is willing to pay, it's a dream．It won't keep our family eating rice," he said．
    小题1:What is expected of the new technology?
    A．To make electricity without polluting the air．
    B．To produce energy without burning coal．
    C．To keep the use of electricity cheaper．
    D．To pump carbon dioxide more easily ．
    小题2:What's the biggest problem the companies are faced with?
    A．How to pump greenhouse gases．
    B．How to deal with the high cost．
    C．How to get along with other partners．
    D．How to improve the new technology．
    小题3:What can be inferred from the passage?
    A．New technologies are unacceptable to people．
    B．It's unlikely to build more new power plants．
    C．The companies are run on a tight budget．
    D．Going green is easier said than done．

    Job sharing refers to the situation in which two people divide the responsibility of one full-time job．The two people willingly act as part-time workers, enough hours between them to fulfill the duties of a full-time worker．If they each work half the job, for example, they each receive 50 per cent of the job's wages, its holidays and its other benefits．
    Job sharing differs from conventional （常规的） part-time work in that it occurs mainly in the more highly skilled and professional areas, which require higher levels of responsibility and employee commitment．    Job sharing should not be confused with the term work sharing, which refers to increasing the number of jobs by reducing the number of hours of each existing job, thus offering more positions to the growing number of unemployed people．Job sharing, by contrast, is not designed to address unemployment problems; its focus, rather, is to provide well-paid work for skilled workers and professionals who want more free time for other activities．
    As would be expected, most job sharers are women．A survey carried out in 1988 by Britain's Equal Opportunities Commission showed that 78 per cent of sharers were female, the majority of whom were between 20 and 40 years of age．Subsequent studies have come up with similar results．Many of these women were re-entering the job market after having had children, but they chose not to seek part-time work because it would have meant lower status．Job sharing also offered an acceptable shift back into full-time work after a long absence．
    The necessity of close cooperation when sharing a job with another person makes the actual work quite different from conventional one-position jobs．However, to ensure a greater chance that the partnership will succeed, each person needs to know the strengths, weaknesses and preferences of his or her partner before applying for a position．Moreover, there must be a fair division of both routine tasks and interesting ones．In sum, for a position to be job-shared well, the two individuals must be well matched and must treat each other as equals．
    小题1:.
    In what way is work sharing different from job sharing?
    A．Work sharing requires more working hours．
    B．Work sharing is aimed at creating more jobs．
    C．Work sharing provides a more satisfactory salary．
    D．Work sharing depends on the employer's decision．
    小题2:.
    According to Paragraph 4, young mothers preferred job sharing to conventional part-time work mainly because _____．
    A．they sought higher social status
    B．they were over ideal working ages
    C．they had difficulty finding full-time jobs
    D．they had to take care of both work and family
    小题3:.
    In job sharing the partners should _____．
    A．enjoy equal social status
    B．have similar work experience
    C．keep in touch with each other
    D．know each other very well
    小题4:.
    The main purpose of the passage is to ______．
    A．describe job sharing in general
    B．discuss how to provide more jobs
    C．recommend job sharing to women
    D．compare job sharing with work sharing

    Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping. Everybody dreams. But only some people remember their dreams. Our dreams often include all the senses (感觉)—smells, sounds, sights, tastes and things we touch. We dream in colour. Sometimes we dream the same dream over and over again. These repeated（重复的） dreams are often unpleasant. They may even be nightmares—bad dreams that frighten us.
    Early in the twentieth century, two famous scientists developed their personal ideas about dreams. Austrian psychiatrist(心里学家) Sigmund Freud published a book called “The Interpretation(诠释) of Dreams” in 1900. Freud believed people often dream about things they want but can’t have. These dreams often have something to do with sex and aggression(侵犯). Swiss psychiatrist Carl Jung worked closely with Freud for several years, but he believed dreams could help people grow and understand themselves. He believed dreams provide solutions(解答) to problems we face when we are awake. He didn’t believe dreams hide our feelings about sex or aggression. Today we know more about the science of dreaming because researchers can take pictures of people’s brains while they are sleeping.
    Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions(感情). Robert Stickgold is a professor of psychiatry at Harvard University in Massachusetts. Doctor Stickgold says that when we dream, the brain is trying to make sense of the world. He does not agree with Sigmund Freud that dreaming is the way we express our hidden feelings and desires(愿望).
    Scientists believe it is important to keep researching dreams. Doctor Stickgold says it has been more than one hundred years since Sigmund Freud published his important book about dreaming. Yet there is still no agreement on exactly how the brain works when we are dreaming or why we dream.
    46. Dreams _________. 
    A. are remembered by everyone
    B. express all that we think in our mind
    C. include few senses and things we touch
    D. are sometimes nightmares(恶梦) that repeat and frighten us
    47. A book on dreaming was published by _________.
    A. Sigmund Freud     B. Robert Stickgold    C. Carl Jung   D. the writer
    48. In the passage, all the psychiatrists _________.
    A. believe dreams can help people understand all the problems that they face
    B. think dreams always hide someone’s feelings about sex or aggression
    C. study dream and dreaming and have their own ideas
    D. have the same idea that people often dream about the things they want
    49. From the passage, we know that _________.
    A. Jung thought that dreams provide solutions to problems we face when we are sleeping
    B. Freud developed the idea that dreams are expressions of people’s hidden feelings
    C. scientists have known quite well why we dream because they can take pictures of our brains
    D. other researchers have discovered how dreaming helps our bodies work with problems and very sad emotions
    50.Which would be the best title(标题) for the passage?
    A. The Explanations of Dreams         B. The Ways of Dreams
    C. The Solutions to Dreams             D. The Mystery(奥秘) of Dreams and Dreaming

    The world’s biggest Internet search engine, Google, has proven once again to be king of the Web. Users can download “Google Wi-Fi” software and then enjoy free Wi-Fi service available in some US cities since last Tuesday.
    Wi-Fi is short for “Wireless Fidelity”(无线上网). It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio sigal.
    A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. Google had already set up two “hotspots” in the US city of San Francisco which provide a free Wi-Fe service.
    The Wi- Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks.
    Wi-Fi is stioo limited to a few cities, where there are “ hotspots”. But its capability(容量) of sending information has already done better than that of the mobile phone network, even that of 3G (Third Generation telecommunication technology). Some scientists have started to call Wi-Fi 4G.
    In addition to a high speed Internet connection, Fi-Fi has other advantages compared to mobile phones. We-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don’t need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.
    小题1: Wi-Fi is not available in cities without_____.
    A．a computerB．a radioC．a hotspotD．a cell phone
    小题2: Which of the following is NOT the advantage of Wi-Fi?

    Our quarrel with efficiency is not that it gets things done, but that it is a thief of time when it leaves us no leisure to enjoy ourselves, and that it strains our nerves when we try to get things done perfectly. In building bridges, American engineers calculate so finely and exactly as to make the two ends come together within one-tenth of an inch. But when two Chinese begin to dig a tunnel from both sides of a mountain both come out on the other side. --The Chinese’s firm belief is that it doesn’t matter so long as a tunnel is dug through, and if we have two instead of one, why, we have a double track to boot.
    　　The pace of modern industrial life forbids this kind of glorious and magnificent idling. But, worse than that, it imposes upon us a different conception of time as measured by the clock and eventually turns the human being into a clock himself. (This sort of thing is bound to come to China, as is evident, for instance, in the case of a factory of twenty thousand workers. The luxurious prospect of twenty thousand workers coming in at their own sweet pleasure at all hours is, of course, somewhat terrifying.)Nevertheless, such efficiency is what makes life so hard and full of excitement. A man who has to be punctually at a certain place at five o’clock has the whole afternoon from one to five ruined for him already. Every American adult is arranging his time on the pattern of the schoolboy - three o’clock for this, five o’clock for that, six-thirty for change of dress, six-fifty for entering the taxi, and seven o’clock for arriving at the destination. It just makes life not worth living.
    小题1:The writer objects to efficiency mainly on the grounds that it ____.
    A．gives us rights to have too much leisure time
    B．urges us to get things done punctually
    C．robs us of leisure time
    D．imposes on us a perfect concept of time
    小题2: In the eyes of the author, the introduction of industrial life gives rise to ____.
    A．the excitement of life
    B．magnificent idling of time
    C．more emphasis on efficiency
    D．terrifying schoolboy
    小题3:The passage tells us ____.
    A．Chinese workers come to work when it is convenient
    B．all Americans are forced to be efficient against their will
    C．Chinese engineers are on better terms with the management
    D．Americans ought not to work so hard for efficiency
    小题4: The author believes that relaxing the rule of punctuality in factories would lead to ____.
    A．great troubleB．increased production
    C．a hard and exciting lifeD．successful completion of a tunnel

    Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.
    The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
    Decibels（分贝）measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
    Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
    A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
    Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
    Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
    小题1: According to the passage, which of the following is increasingly dangerous to sea creatures?
    A．The man-made noises.B．The noises made by themselves.
    C．The sound of earthquakes.D． The sound of the ice-breaking.
    小题2: Which of the following is discussed in the third paragraph?
    A．Different places with different types of noises.
    B．The very human ears sensitive to all types of noises.
    C．The ocean animals' reaction to noises.
    D．The same noise measured differently on land and in the ocean.
    小题3:We can know from the passage that many researchers think that the noise limit of one hundred twenty decibels would _____.
    A．prevent them from doing their research work
    B．benefit them a lot in their research work
    C．do good to their health
    D．increase the industrial output
    小题4: According to the passage, what will scientists most probably do in the future?
    A．They will try their best to decrease noise.
    B．They will work hard to cut down noise pollution.
    C．They will study the effect of different noises.
    D．They will protect animals from harmful noises.

    The journey two naval (海军) officers made some time ago to tile very deepest point on the earth makes us realize how much of the world still remains to be explored (探测). The two men went down several miles to the bottom of the Pacific Ocean hiding in a small steel ball called a “bathy-scaphe” to find out if there are any ocean currents (急流) or signs of life.
    It was necessary to set ont early, so that the bathyscaphe would come to the surfacc in daylight, and so be easily found by the mother ship which would be waiting for it. The divers began preparations at dawn and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.
    In time, the temperature dropped to freezing-point and the men trembled inside the ball. They kept in touch with the mother ship by telephone describing how they felt. Then, at a depth of 3 000 feet, the telephone stopped working and they were quite cut off from the outside world. At 30 000 feet, the men were surprised by a sudden, loud noise-------even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the bathyscaphe touched the soft ocean floor, raising a big cloud of “dust” made up of different kinds of small, dead sea animals. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by thc very large wate-pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the weak but clear voices of the officers were heard on thc mother ship. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none the worse for their experience.
    小题1:The officers started their journey at dawn___.  
    A．because they wanted to return to the mother ship in twenty four hours
    B．because the sea then was calm
    C．when the sun was not too strong
    D．so that they could return before dark
    小题2:What did the officers find out at the bottom of the sea?  
    A．They only found different dead sea animals.
    B．They did find signs of life.
    C．There was no signs of any life.
    D．There was only dust.
    小题3:The journey to the bottom of the sea helped us to realize that______. 
    A．much of the world hasn’t yet been explored
    B．there are not any signs of life at the bottom of the sea
    C．strong water-pressure has great effect on fish
    D．powerful lights can not be turned on at the ocean floor without killing fish
    小题4:Which of the following is closest in meaning to “They were cold and wet through, but none the worse for their experience”?   
    A．They were cold and wet through, which was the worst thing of all.
    B．They were even worse than cold and wet through at the bottom of the sea.
    C．Considering what they had just experienced, being cold and wet through was not too
    bad.
    D．For such an experience, being cold and wet through was not bad for them at all.
