A new factory that turns used wine bottles into green sand could revolutionize the recycling industry and help to filter(過濾)the nation's drinking water.
For the last 100 years special high grade white sand quarried(開采)at Leighton Buzzard in Bedfordshire has been used to filter tap water to remove bacteria and impurities—but this may no longer be necessary.
The green sand has already been successfully tested by water companies and is being used in 50 swimming pools in Scotland to keep the water clean.
Backed by one million pounds from the European Union and the Department for Environment, Food and Rural Affairs(Defar),a company based in Scotland is building a factory to turn beverage bottles back into the sand from which they were made.
The idea is not only to avoid using up increasingly scarce sand in Scotland and avoid any further quarrying but also to solve a crisis in the recycles only 750 000 tones of it.
Howard Dryden, the scientist and managing director of the company has spent six years working on what he calls Active Filtration Meadia, or AFM, the recycled glass. He says he needs bottles that have already contained drinkable liquids to be sure that drinking water would not be polluted.
"The fact is that tests show that AFM does the job better than glass, it is easier to clean and reuse and has all sorts of properties that make it ideal for other applications, "he claimed. He also thinks the market will be able to take 250 000 tones of green sand a year. The plan is to build five or six factories in cites in UK where the bottles come from to cut down on transport.
The factory will be completed this month and is expected to go into full production on January 14 next year. Once it is providing a "regular" product, the government's drinking water inspectorate will be asked to perform tests and approve it for general use by water companies.
小題1:It may no longer be necessary to use high-grade white sand to keep water clean because_____.
A.there is no need to keep water clean
B.A new factory has been set up
C.The green sand has been used to keep the water clean
D.White sand is being use up
小題2:According to the passage ,the new idea can do the following except_____.
A.avoiding using up increasingly scarce sand
B.avoiding further quarrying of white sand
C.solving the crisis in the recycling industry
D.cutting down the cost on transport
小題3:Tests show that ______ in keeping the water clean.
A.AFM is more efficient than white sand
B.AFM is more efficient than glass
C.glass is more efficient than AFM
D.white sand is more efficient than green sand
小題4:The underlined word "Backed" in the third paragraph can best be replaced by"_____".
A.AllowedB.Opposed
C.SupportedD.Forbidden
小題5:What would be the best title for the passage?
A.Revolution in the Recycling for the Industry.
B.Modern Technology an New Markets.
C.Revolution in Environmental Protection.
D.Unlocking the Benefits of Green Sand.

There is a small shop about 200 meters from where I live that sells groceries, meat and other basic necessities.

One of the most fascinating things about television is the size of the audience. A novel can be on the “best seller” lists with a sale of up to 100,000 copies, but a popular TV show might have 70
million TV viewers. TV can make anything or anyone well-known overnight.
This is the principle behind “quiz” or “game” shows, which put ordinary people on TV to play a game for prizes and money. A quiz show can make anyone a star, and it can give away thousands of dollars. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show’s producers, who were pulling the strings, gave the answers to the most popular contestants beforehand. Why? Because if the audience didn’t like the person who won the game, they turned the show off. The result of this cheating was a huge scandal(丑聞). Based on the show off, a movie titled “Quiz Show” is on 40 years later.
Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren’t taken seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating(羞辱) them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions.
小題1:What is the most important thing as to television?
A.How many viewers they can attractB.Becoming the best seller on the list
C.How much money can be given awayD.The number of people attending shows
小題2:What does the underlined part “pulling the strings” probably mean?
A.Planning the shows with effortB.Drawing the curtain on the stage
C.Controlling the result secretlyD.Playing “quiz” or “game” openly
小題3:Charles Van Doren stopped his career as a television personality because ________.
A.he had earned enough wealth and fame.
B.one of the participants had told the truth
C.the film “Quiz Show” was being shown
D.his frequent appearance had bored the audience
小題4: It can be inferred from the passage that _______.
A.TV Game Shows are more popular than before.
B.the scandal was not made known until 40 years later
C.getting money is the only purpose of people taking part in shows
D.people can make themselves famous by taking part in shows

I sometimes wonder if old Finchley has the right personality to be a research scientist. He keeps asking when he’ll be coming back. After all, it was his own fault. Nobody tries out what has just been invented on themselves any more but Finchley. Well, he must have pumped about a thousand c. c. s into himself before I noticed he was clearly becoming smaller.
It was funny watching him, because his clothes remained the same in size. They simply piled up around him so that he looked like a small boy in his father’s clothes. But he kept getting smaller and smaller. As my colleague Dawson and I watched him, he disappeared! All we could see was Finchley’s clothes on the floor. They looked so strange, because the lab coat was on top, shirt and trousers inside and, I suppose, underclothes inside again. It gave me a strange feeling, and I think Dawson was a bit shaken, too.
Dawson was sitting on his chair in front of a microscope he’d been using to examine a family of mites(螨蟲). He looked through the scope kind of absently again, and was nearly scared to lose awareness when he found old Finchley waving back from the other end.
It seems as if Finchley had taken a free ride on a dust mite and landed on the land of the mite family. Of course, we didn’t know till Finchley told us later. But anyhow, as I said, Dawson nearly passed out. He jumped off his chair and pointed at the microscope, to shocked to speak.
小題1:Finchley disappeared because ________.
A.he took something poisonous
B.he was changed into a dust mite
C.his father’s clothes totally covered him up
D.what he and his colleagues invented resulted in his disappearace
小題2: It frightened Dawson to see Finchley _______.
A.got into his scope by accidentB.was waving through his telescope
C.suddenly got lost in his clothesD.gradually disappeared in the lab
小題3: It can be inferred that Finchley, Dawson and the writer have possibly invented _____.
A.some kind of medicineB.a new powerful microscope
C.a machine to make people smallD.a new way to make a culture of mite
小題4: It can probably be concluded that Finchley ________.
A.passed out there and thenB.is not fit to be a scientist
C.is a devoted scientistD.will remain tiny all the time

  Do you now who Stefani Germanotta is? Perhaps not, but you’ll almost certainly know the star called Lady Gaga, a 24-year-old American famous for her cutting edge pop videos and strange fashion sense. She was the biggest winner at the MTV Europe Music Awards in Madrid on November 7, 2010. Her awards included the best female artist and the best song.
Her popularity doesn’t end there. The BBC reports that the University of South Carolina has a sociology course about the life, work and rise to fame of Lady Gaga. The course is due to start in spring 2011. “We’re going to look at Lady Gaga as a social event,” said professor Mathieu, who will teach Lady Gaga and the Sociology of Fame.
Germanotta, in fact, is a college student. She learned to play the piano by age 4. At age 17, she was one of the only 20 young people to get early admission to New York University’s Tisch School of the Arts, the famous music school. Yet after her second semester, she took a big risk—she decided to quit and concentrate on a music career. But hwo did she manage to go from nowhere to supar star in just two years?
She may well have had a plan for the top. She created “The Ultimate Pop Burlesque Show” with another artist. It was the first of many strange images. The pair gained enough attention to get a spot at a famous music festival in Chicago. Later, a record company signed Germanotta.
While Lady Gaga enjoys popularity, there are critics accusing her of regularly using rude language in her lyrics(歌詞) and wearing overly sexy clothing.

        Eat to Excel
        How fit are you? Do you look after yourself? Do you eat healthily or do you eat anything you like? Premier League football club Aston Villa are encouraging their players and local children to eat healthy food. They know that what you eat is the key to success.
        How fit is a footballer?
        Could you run ten kilometers in 90 minutes? A professional footballer can. Footballers have to be strong, quick, skillful and creative in their moves. Every Premier League club makes sure it has a good coaching scheme and a well-planned fitness program. They also ensure that players have the practice and training that will prepare them for matches. What else do you think clubs pay special attention to? A good stadium? Anything else? What about the food they eat?
        Eating the right thing
        A good diet is a fundamental part of sport these days. Aston Villa manager Martin O’Neill’s sport and health experts have chosen a secret weapon --- organic food (food grown without chemicals). Fitness manager Jim Henry eats with his players and said: “I chose to switch to organic food for Aston Villa because I’ve read studies showing that organic food has higher levels of vitamins, minerals and antioxidants.” He believes that the best way to get these is to eat the very best fresh food.
        What to eat after the match
        Head chef at Aston Villa, lan Edge, feeds players with the best food as soon as they finish an away match. He says: “Food is very important to sports stars and particularly after a game. There is an hour of opportunity when they need to eat to get the best muscle strength, so I hand out meals on the coach on the way home. If we can make one per cent difference to the players by using organic food, then it is worth it.”
        Teaching healthy eating
        Everyone at Aston Villa enjoys organic food at their training ground. But the club is also worried about the unhealthy diet among local children who prefer sweets and unhealthy fast food. As part of their work in the community, Aston Villa has opened up their kitchen and invited children from local schools to come and learn how to cook with the help of the Villa head chef. Villa midfielder, Nigel ReoCoker, visited the children on the opening day. “The kitchen promotes healthy eating and a healthy lifestyle.” he said.
        A final word from the kitchen
        Head chef Ian says: “Footballers know how important food is to their profession and nine times out of ten, they go for the healthiest option.” Do you watch your diet? If you do and you keep yourself fit, you can be a winner!
        小題1:Every Premier League Club provides footballers with ______________.
        A.a good coach
        B.a fitness center
        C.proper practice and training
        D.a delicious diet

        A.he believes the studies he has read about organic food
        B.he will only eat organic food with his players
        C.he thinks food is especially important after a game
        D.he chose organic food as a secret weapon for footballers
        小題3:We can learn from the passage that ___________________.
        A.people can make one percent difference to players by using organic food
        B.only a few footballers pay attention to the healthy eating
        C.footballers in Aston Villa usually eat on their way to the match
        D.footballers in Aston Villa usually eat some food within an hour after a match.
        小題4:Why has Aston Villa invited children from local schools?
        A.Because they want to teach kids how to cook delicious food.
        B.Because they want to teach kids to play football.

        Take a look at the following list of numbers: 4, 8, 5, 3, 7, 9, 6. Read them loud. Now look away and spend 20 seconds memorizing them in order before saying them out loud again. If you speak English, you have about a 50% chance of remembering those perfectly. If you are Chinese, though, you’re almost certain to get it right every time. Why is that? Because we most easily memorize whatever we can say or read within a two-second period. And unlike English, the Chinese language allows them to fit all those seven numbers into two seconds.
        That example comes from Stanislas Dahaene’s book The Number Sense. As Dahaene explains: Chinese number words are remarkably brief. Most of them can be spoken out in less than one-quarter of a second (for instance, 4 is “si” and 7 “qi”). Their English pronunciations are longer. The memory gap between English and Chinese apparently is entirely due to this difference in length.
        It turns out that there is also a big difference in how number-naming systems in Western and Asian languages are constructed. In English, we say fourteen, sixteen, seventeen, eighteen and nineteen, so one might expect that we would also say oneteen, twoteen, threeteen, and fiveteen. But we don’t. We use a different form: eleven, twelve, thirteen and fifteen. For numbers above 20, we put the “decade” first and the unit number second (twenty-one, twenty-two), while for the teens, we do it the other way around (fourteen, seventeen, eighteen). The number system in English is highly irregular. Not so in China, Japan, and Korea. They have a logical counting system. Eleven is ten-one. Twelve is ten-two. Twenty-four is two-tens-four and so on.
        That difference means that Asian children learn to count much faster than American children. Four-year-old Chinese children can count, on average, to 40. American children at that age can count only to 15. By the age of five, in other words, American children are already a year behind their Asian friends in the most fundamental of math skills.
        The regularity of their number system also means that Asian children can perform basic functions, such as addition, far more easily. Ask an English-speaking seven-year-old to add thirty-seven plus twenty-two in her head, and she has to change the words to numbers (37+22). Only then can she do the math: 2 plus 7 is 9 and 30 and 20 is 50, which makes 59. Ask an Asian child to add three-tens-seven and two-tens-two, and then the necessary equation(等式) is right there, in the sentence. No number translation is necessary: it’s five-tens-nine.
        When it comes to math, in other words, Asians have a built-in advantage. For years, students from China, South Korea, and Japan --- outperformed their Western classmates at mathematics, and the typical assumption is that it has something to do with a kind of Asian talent for math. The differences between the number systems in the East and the West suggest something very different --- that being good at math may also be rooted in a group’s culture.
        小題1:What does the passage mainly talk about?
        A.The Asian number-naming system helps grasp advanced math skills better.
        B.Western culture fail to provide their children with adequate number knowledge.
        C.Children in Western countries have to learn by heart the learning things.
        D.Asian children’s advantage in math may be sourced from their culture.
        小題2:What makes a Chinese easier to remember a list of numbers than an American?
        A.Their understanding of numbers.
        B.Their mother tongue.
        C.Their math education.
        D.Their different IQ.
        小題3:Asian children can reach answers in basic math functions more quickly because ____________.
        A.they pronounce the numbers in a shorter period
        B.they practice math from an early age
        C.English speaking children translate language into numbers first
        D.American children can only count to 15 at the age of four

                      Our bodies are wonderfully skillful at keeping balance.When the temperature jumps, we sweat to cool down.When our blood pressure falls, our hearts can do something.As it turns out, though, our natural state is always changing.Researchers are finding that everything from blood pressure to brain function changes regularly with the cycles of sun, moon and seasons.And their insights (洞察力) are getting new ways for keeping away such common killers as heart disease and cancer.Only one doctor in 20 has a good knowledge of the scientific use of time in medicine.But according to a new American Medical Association, three out of four are eager to change that.“The field is exploding,” says Michael Smolensky.“Doctors used to look at us like, What spaceship did you get off ? Now they're thirsty to know more.”
        In medical school, most doctors learn that people with chronic  conditions should take their medicine regularly.“It’s a terrible way to treat disease,” says Dr Richard Martin.For example, asthmatics (氣喘患者) are most likely to suffer during the night.Yet most patients try to keep a constant level of medicine in their blood day and night, whether by breathing in on an inhaler (吸入器) four times a day or taking a pill each morning and evening.In recent studies, researchers have found that a large mid afternoon dose of a bronchodilator (支氣管擴張劑) can be as safe as several small doses, and better for preventing nighttime attacks.
        If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease.Heart attacks are twice as common at 9 a.m.as at 11 p.m.Part of the reason is that our blood pressure falls at night, then rises as we start to work for the day.“Doctors know that,” says Dr.Henry Black of Chicago's Medical Center, “but until now, we haven't been able to do anything about it.” Most blood - pressure drugs provide 18 to 20 hours of relief (減緩).But because they’re taken in the morning, they're least effective when most needed.“You take your pill at 7 and it's working by 9,” says Dr.William White of the University of Connecticut Health Center “But by that time you've gone through the worst four hours of the day with no protection.” Bedtime medicine would prevent high blood pressure, but it would also push blood pressure to dangerously low levels during the night.
        小題1:Researchers are finding that _________ .
        A.heart disease and cancer are the most common killers of human beings
        B.only blood pressure and brain function are decided by cycles of sun, moon and seasons
        C.the functions of human bodies have much to do with nature
        D.any change in human bodies goes with changes in the surroundings
        小題2:According to the author, it is best for asthmatics to take their medicine _________ .
        A.at certain time
        B.each morning and evening
        C.when the disease occurs
        D.at midafternoon
        小題3:Which of the following statements is NOT true?
        A.Doctors know more about illnesses than before.
        B.Doctors in the U.S.used to be thirsty to know more about the new medical field.
        C.The researchers' insights are providing new methods to prevent common killers.
        D.The correct use of time in medicine attracts more attention in medical circle in the U.S.A.
        小題4:The suggested title for this passage might be _________.

        “BANG!” the door caused a reverberation(回聲).It was just standing there, with Father standing on one side, and I on the other side.
        We were both in great anger.“Never set foot in this house again!” stormed Father.With tears welling up in my eyes, I rushed out of the flat and ran along the street.
        The street lights were shining rather desolately(凄涼的).I wandered aimlessly.
        A young father who held a child in his arms walked past me.I felt as if I saw my childhood from another space: happy and harmonious.
        But now… I don’t know whether it is because I have grown up or because dad is getting old.We differ in our ways of thinking.He always imposes his opinions and codes of behavior on me.Whenever I do something wrong, he never admits it.We are just like two people coming from two different worlds.It feels like there is an iron door between us that can never be opened.
        I wandered the streets, without a destination in mind.My heart was frozen on this hot summer night.As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company.When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.
        In fact, it was nothing.Perhaps, dad was throwing away some of his old stamps.Perhaps he thought they were useless.I never had the courage to tell him that I liked collecting stamps.I can’t stand his outrageous(蠻橫的) words: “ I can throw you away, let alone these old papers.”
        All the lights were off except father’s.
        Dad was always like this.Maybe he didn’t know how to express himself.After shouting at me, he never showed any mercy or any moments of regret.After an argument he has the habit of creeping up in my sleep and then tucking me underneath the covers.
        This was how he always was.He has been a leader for so long that telling everyone else what to do has become his second nature.
        The light was still on.“Am I wrong?” I whispered, maybe… With the key in hand, I was as nervous as I had ever been.At last, I decided to open the door.As soon as I opened the door, tears ran down my cheeks.I suddenly realized that the iron door that I had imagined between us did not exist at all.Love is second to none.
        小題1:Decide which is the best order of the following according to what happened in the passage.
        a.I opened the door and entered the house.
        b.Sadly I ran out into the street.

        For photographers lacking training, experience and even the ability to click a shutter button, they produce remarkable pictures.Under the sea, deep in the woods and high in the sky, furry, feathery and leathery-skinned creatures are opening up vistas(遠景)by taking cameras where no human can go.
        This is the world of animal-borne imagine celebrated last month at a conference sponsored(supported) by the National Geographic Society for the 20th anniversary of its Crittercam, the device that started it all.
        Since its debut(首次公開露面)in 1987 on the back of a turtle, the Crittercam and similar devices developed by others have grown smaller and more powerful.
        “It’s more than just a camera now,” said Greg Marshall, the marine biologist and now filmmaker who invented the Crittercam.“We are now including more instruments to gather more data while at the same time reducing everything in size.”
        The idea of attaching video cameras to animals came to Mr.Marshall in 1986 on a dive off Belize when a shark apporached him.When the animal quickly turned away, he noticed a shark with a sucker fish on its belly.He came up with the idea that putting a camera in place of the sucker fish would allow people to witness the shark’s behavior without disturbing it.
        Crittercams have been attached to sharks, sea lions and other marine animals, and, more recently, to land animals.
        Birds are a new addition, Mr.Marshall said.Dr.Christian Rutz of Oxford recently reported on tiny cameras called feathercams that monitor the crows in the South Pacific.It has discovered that crows are smarter than anyone knew they not only use twigs(嫩枝)and grass stems as tools to root out food, but they also save their favorite tools to use again.
        Tracey L.Rogers, director of the Australian Marine Mammal Research Center in Sydney, said crittercam was a powerful tool in her work with leopard seals(豹斑海豹)in Antarctica.“In studying animals,” Dr.Rogers said at the meeting, “you want to see how our animal models align(與……一致)with reality.With a camera, you actually see what they do.You don’t have to guess.”
        小題1:What’s the text mainly about?
        A.The advantages of crittercam.
        B.The development of Crittercams in the past 20 years.
        C.How crittercam was invented.
        D.How crittercam works.
        小題2:What inspired Marshall to invent crittercam?
        A.The sight of sucker fish clinging to a shark on a dive.
        B.The thought of how to photograph animals better.
        C.Noticing a shark eating a sucker fish on a dive.
        D.Seeing a shark with a camera on its belly on a dive.
        小題3:According to Dr.Rogers, crittercam ____.
        A.can clear up all your doubts about animals
        B.is the most powerful tool in studying animals
        C.enabled her to observe the crows in the South Pacific closely
        D.helped a lot with her research on leopard seals in Antarctica
