    When coal is burned in a boiler, two kinds of ash by-products are produced: a heavy bottom ash and a fine-as-powder fly ash. About 10 to 15 percent of the coal by-product is bottom ash which is used like sand on streets and highways covered with ice, and also on highways as paving material.
    It is the fly ash, however, that is receiving much attention. Once considered a waste, fly ash is now regarded as a natural resource in the United States. It can be placed in some lower places, where it is compacted and covered with soil, for the seeds of various grasses and plants to be placed in the soil to make the land productive.
    Fly ash may be added to concrete to build roads and other kinds of buildings, taking the place of the cement up to 20 percent. As a by-product of burned coal, fly ash requires no extra energy to be produced, while cement production requires great amounts of energy.
    Besides, the technology is able to take out some useful minerals from the fly ash, which is still a very expensive process today. But the time may come when it is cheaper to take out these products from ash than to mine new supplies.
    小题1: The bottom ash can be put on icy streets________.
    A．in order to rebuild themB． in order to make them colourful
    C．so that people can walk on themD．so that cars can run faster
    小题2:The fly ash_______ bottom ash.
    A．has the same use asB． is more expensive than
    C．has more uses thanD．is much cheaper than
    小题3:The fly ash can be used to________.
    A．grow various plantsB． take the place of soil
    C．cover productive landD．make more productive land
    小题4: Which of the following is right?
    A．To produce fly ash, some extra coal is to be burned.
    B． Fly ash is made while producing cement.
    C．It takes less energy to produce fly ash than cement.
    D．Fly ash is a costless by-product.
    小题5:The word “mine” in the last sentence of the passage means_______.
    A．to buy things from other countries
    B． to search for useful materials in the mountains
    C．to dig deeply into the ground to get useful materials

    For a small but increasing  number of young women in modern-day China, true love is all about the numbers. A potential suitor may have a good sense of humor and reasonable good looks, but what they say really matters is if he owns an apartment and how many square feet it is. A sizable bank account is also a must, and, some say, so is a luxury car。
    At least, that’s the way things look if you watch Chinese television these days. The latest reality-TV scandal to shock the nation involves Ma Nuo, a 22-year-old model from Beijing who appeared on China's most popular dating show, If You Are the One. She rejected an offer from a male contestant to take a ride on his bike. "I'd rather cry in a BMW (宝马) car than laugh on the backseat of a bicycle," Ma told her suitor with a giggle.
    The televised words swept the Internet and made an instant celebrity of Ma, who becomes one of the most talked-about women in the country. The reaction  among young Chinese was especially severe, reflecting growing anxieties over the widening gap between rich and poor, shifting societal values and public attention on the difficulties of finding a mate in a country where men are expected to outnumber women by 24 million in a decade.
    As disgusted as they have been by some of the contestants, viewers continue to watch religiously. Why are people still tuning in? "Audiences like programs because they are honest. They show the current reality of Chinese society," says Yan Mu, one of the founders of Baihe.com. Young people are so focused on making money and building their careers these days, they have little time to devote to dating, he says. "Many people feel pressure from their parents and peers," Yan adds. " It can be a struggle to find a partner." Money may not buy you love. But on China's reality shows, it can at least get you a date.
    小题1:The underlined words“numbers”in the first paragraph include the following except_______
    A．the age and degreeB．the size of the houseC．the sum of the depositD．the price of the belonging
    小题2:What does Ma Nuo mean by saying“I’d rather cry in a BMW car than laugh on the backseat of a bicycle.”in the second paragraph?
    A．When she is in a BMW car, she will cryB．When she is on a bike, she will laugh
    C．She prefers money to true loveD．She prefers true love to money
    小题3:Why do many young men take part in TV dating shows?
    A．because they think they may get true love from them
    B．because they think China’s reality shows can at least give them a chance to date
    C．because their parents and peers force them to do so
    D．because viewers like dating shows
    小题4:Which one of the following statements is TRUE according to the passage?
    A．some contestants have been disgusted because they are dishonest
    B．young people are too busy to take part in dating shows
    C．some people are worried that societal value are changing
    D．Ma Nuo rejected the bike offered by the contestant
    小题5:What is the best title of the passage?
    A．China’s TV Dating ShowB．Date for Love or money
    C．Date Makes You a CelebrityD．Popular TV Dating Show

    Would you like to be a king or queen? To have people waiting on you hand and foot? Many Americans experience this royal treatment every day. How? By being customers. The American idea of customer service is to make each customer the center of attention. Need proof? Just listen to the commercials. Most of them sound like the McDonald’s ad: “We do it all for you.” Actually, not all stores in America roll out the red carpet for their customers. But wherever you go, good customer service means making customers feel special.
    People going shopping in America can expect to be treated with respect from the very beginning. Most places don’t have a “furniture street” or a “computer road” which allow you to compare prices easily. Instead, people often “let their fingers do the walking” through the store hot lines. From the first “hello”, customers receive a satisfying response to their questions. This initial contact can help them decide where to shop.
    When customers get to the store, they are treated as honored guests. Customers don’t usually find store clerks sitting around watching TV or playing cards. Instead, the clerks greet them warmly and offer to help them find what they want. In most stores, the clear signs that label each department make shopping a breeze. Customers usually don’t have to ask how much items cost, since prices are clearly marked. And unless they’re at a flea market or a yard sale, they don’t bother trying to bargain.
    When customers are ready to check out, they find the nearest and shortest checkout lane. But as Murphy’s Law would have it, whichever lane they get in, all the other lanes will move faster. Good stores open new checkout lanes when the lanes get too long. Some even offer express lanes for customers with 10 items or less. After they pay for their purchases, customers receive a smile and a warm “thank you” from the clerk. Many stores even allow customers to take their shopping carts out to the parking lot. That way, they don’t have to carry heavy bags out to the car.
    小题1: By quoting (引用) the McDonald’s ad: “We do it all for you”, the author intends to_______.
    A．suggest that customers believe what commercials say deeply
    B．show readers the American idea on good customer service
    C．express all the stores pay much attention to the customers
    D．persuade readers to choose the stores with ads correctly
    小题2:In the USA, what may you do at first if you want to do some shopping?
    A．To visit a professional street with lots of similar stores.
    B．To compare prices in many shops in the same street.
    C．To make phone calls and get better shopping choices.
    D．To receive other customers’ answers to the questions.
    小题3:The underlined words “a breeze” in Para.3 most probably means _________.
    A．an easy jobB．a trouble　　C．a funny thing　　D．a boring task
    小题4:Which of the followings shows American stores offer convenience to customers in this passage?
    A．The store clerks don’t usually sit around watching TV or playing cards.
    B．Some stores offer price bargain to the customers like a yard sale.
    C．The clerks give customers a smile and a warm “thank you” after paying.
    D．Some stores open new checkout lanes when the lanes are crowded.
    小题5:Which of the following can be the best title of this passage?
    A．Customer Service in AmericaB．Excellent Stores in America
    C．Shopping Rules in AmericaD．Being King or Queen in America

      The 1980s was called the “Me Decade” because for many this time was marked by a fascination with the self. The idea that each person has a self may seem natuaral to us, but this concept is actually quite new. The idea that each human life is unique developed between the 11th and 15th centuries in Europe. Before that time, individuals were considered in relation to a group, and even today, many eastern cultures place more emphasis on the importance of a collective self than on a unique and independent self.
    Both eastern and western cultures see the self as divided into an inner, private self and an outer, public self. But where they differ is in terms of which part is seen as the“real you.” Western culture tends to promote the idea of individuality—a self that is separated from other selves. In contrast, many eastern cultures focus on an inter-independent self that gets its diversity in large part from inter-relationship with others.
    For example, a Confucian(孔子) idea stresses the importance of “face”—other people’s views of the self and maintaining one’s desired status in their eyes. In the past, some Asian cultures developed clear rules about the specific clothes and even colors that people in certain social classes and occupations were allowed to display, and these live on today in Japanese style manuals. This style of dress is at odds with such western practices as “casual Fridays,” which encourage employees to dress informally and express their unique selves.
    小题1: Which is true about the self according to the text?
    A．Many eastern cultures see the self connected with others.
    B．Those born in the 1980s are generally most self-centered than others.
    C．The concept that eac person has a self may seem strange to eastern cultures
    D．Western cultures regard the self as an outer, public self while eastern cultures don’t.
    小题2: What does the 2nd paragraph mainly talk about?
    A．How eastern and western cultures see the self.
    B．Eastern cultures contrast sharply with western cultures
    C．Both eastern and western cultures appreciate the importance of self
    D．Eastern cultures are as important as western cultures
    小题3: A Japanese dress code is mentioned in the last paragraph to _________.
    A．explain the importance of “face”
    B．say how traditional the Japanese are
    C．emphasize the importance of eastern cultures
    D．show how eastern cultures see the self in relation to others
    小题4: The underlined phrase “at odds with” most probably means_______.
    A．in agreement withB．in disagreement with

    In many parts of the world cars play an essential role in daily life and many societies would stop to function without them. So the claim that in 20 years’ time no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously not only by governments but also by car manufacturers.
    The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized, which will mean extremely large fuel savings, no accidents and better use of roads. The super-intelligent car of the 21st century will drive itself and it will not be owned by on individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.
    According to Dr. David Davis, who leads the research team, these predictions are based on the rising cost of the car culture ,which had blocked up our cities, polluted our air and caused more deaths than both world wars put together.
    Davis says cars will be fitted with intelligent cruise control devices to regulate the distance between one car and another. Brakes and accelerators (加速器) will become redundant（多余的） because the car will automatically speed up or slow down to match the speed of the car in front. Computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people.
    By 2010 Dr. David Davis believes car technology will give motorists a clear view of the road whatever the weather conditions by projecting an image of the road ahead onto the car’s windscreen. And by 2020 cars will travel in convoy linked to each other electronically. Cars will be connected by an electronic tow(牵引) bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the ordinary fuel” says Davis. “But all the others in the train would burn about ten percent of the normal amount and so produce about ten percent of the pollution.
    小题1:We know from the passage that governments and car manufactures ________.
    A．don’t believe the prediction that no one will own cars by 2020.
    B．are devoted to the technological innovation (创新) in car industry.
    C．consider the predictions made by the researchers seriously.
    D．have put the super-intelligent car into mass production.
    小题2:Which of the following will NOT be the characteristics of the cars of 2020 ?
    A．There will be no brake and accelerator in cars.
    B．We will own as many cars as we want .
    C．All cars will be driven by computers.
    D．Car accident will no longer happen.
    小题3:The expression closest in meaning to the underlined phrase “ in convoy”(Para 5) is ______.
    A．in lineB．sidelongC．side by sideD．next to one another
    小题4:What will happen if cars are linked to each other electronically in 2020 ?
    A．Motorists will get a clear view of the road.
    B．The weather conditions won’t have effect on motorists.
    C．There will be a decrease in the pollution caused by car .
    D．All trains will burn less fuel than present.

    Washington, April 4----- The United States has more than 90 million families for the first time, but each contains fewer people on average than ever, the Census Bureau(统计局) reported today.
    The 90,031,000 families in the United States averaged 2.64 members each as of last July 1.“The reason is, in effect, changes in the age structure,” explained Campbell Gibson, a population researcher for the bureau. Most Americans born in the great explosion of births are now in their 20’s and 30’s when they most likely to set up families, he said.
    The fact that many are doing so increased the number of families from 80.4 million in 1980 t0 88.8 million in 1986 and past the 90 million mark last summer.
    At the same time, the average number of people per family dropped from 2.75 in 1985 to 2.65 in 1986 and then to 2.64, Mr Gibson said.
    By comparison, the 1970 Census found the average family contained 3.14 people. Families averaged more than four people in 1939 and more than five in 1880.
    The growing number of ever---- smaller families is still going on, but Mr Gibson pointed out that family growth was not the same as population increase in the 1970’s.
    The same age factors that are increasing the number of families also happened then, but in the 1970’s the proportion(比例) of families in each age group was also growing.
    That hasn’t continued in the 1980’s for a number of possible reasons, Mr Gibson said. For example, in the 1980’s more young people have chosen to remain home with their parents instead of setting up housekeeping on their own, as many did in the 1970’s.
    This could be caused by the increasing cost of housing, he said. Delays in marriage while young people go to work and school, have also been widely reported as a factor, but it was not the only factor for the family changes.
    小题1:The smaller figure of families reported here is _________.
    A．1980B．80,400,000C．2.64D．90 million
    小题2:What’s the reporter’s attitude towards the present situation?
    A. People should get married at later age.
    1. The average number of family members should be 2.64.
    2. It’s not clear in the report.
    3. Young people should set up housekeeping on their own, as many did in the 1970’s.
    小题3:From the last paragraph we may infer that________.
    A. delay in marriage will not help the number of the families
    1. delay in marriage is the major factor of the family changes
    2. the writer felt sorry that many young people now delay their marriages
    3. there must be some other factors which have led to the slower growth in the 1980’s
    小题4: The underlined word “factor” in the passage means_________.
    A．reasonB．something that proves be true
    C．advantageD．something that helps to bring about a result

    In Britain, in a population of 60 million, there are 13 million grandparents, many of whom live alone a long way from their grandchildren.The loneliness of these older people has become an issue that schools are trying to teach children about .
    On a popular teacher’s website, there is a classroom activity to help make children aware of the implications of the different generations of the same family living far from each other. It’s a story about Mrs. Eiderdown, an elderly lady whose grandchildren have moved to Australia with their parents. She lives alone and rarely sees her family .
    First of all, the children speculate about Mrs. Eiderdown’s life.  What does she have for breakfast ? what does she do all day ?how does she feel about her life ?
    One day, Mrs. Eiderdown decides that she wants a pet to keep her company and puts an advertisement in a local shop window. Then she waits at home to see if anyone will answer her advertisement .
    A tall thin man rings her doorbell. he is holding a cardboard box. Mrs. Eiderdown chats with the man for ten minutes before she realizes that she hasn’t looked in-side the box to see what the pet is. She can hear a his-sing sound. The children guess what is in the box(a snake). Mrs. Eiderdown thanks the man but says she doesn’t think the snake is a good idea .
    The next time the doorbell rings, there’s a lady on the doorstep, also carrying a cardboard box.In the bottom of the box, Mrs. Eiderdown sees something black and hairy with eight legs. Again ,the children say what they  think it is (a spider). Mrs. Eiderdown thanks the lady for her kindness but says that a spider is not the sort of pet she has in mind.
    At last, the little girl next door brings her a dog .Mrs. Eiderdown’s life improves a lot because of the dog. more importantly, of course, the little girl, whose own granny lives a long way away, starts to visit Mrs.Eiderdown more often. This interactive classroom idea has led to a greater awareness among children about the possible loneliness of older people who live quite near them .
    小题1:what’s the main idea of the passage?
    A．children get to know about the trouble of the elderly
    B．neighbors help select pets for Mrs. Eiderdown
    C．society helps the lonely people in the UK
    D．school send pets to the lonely elderly

    A．they talk about how she feels about being old
    B．they try to experience her loneliness
    C．they try to imagine how she lives
    D．they write about her life story
    小题3:what can we infer from the passage ?
    A．the little girl often visits her own granny
    B．the people who offer pets are lady’s neighbors
    C．the farther the elderly live ,the lonelier they feel
    D．the little girl begins to care more about Mrs. Eiderdown
