    Scientists warn today that the Atlantic bluefin tuna（金枪鱼）faces disappearance unless certain action is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna worldwide are more dangerous than anyone has imagined.
    The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A good one can fetch as much as £ 52,000 in the Tokyo fish markets. “In my lifetime, we’ve brought this big fish to the doorstep of death in the western Atlantic Ocean,” said Barbara Block of Stanford University in California. “The electronic way of tracks provides the best scientific information we’ve ever had to manage these tuna and we must, as an international community, start to act actively to make sure of the future of this fish. ”
    Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore in search of deep ocean fish. Tuna—in the Mediterranean and Japan—have been under increasing pressure for years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since 1969．There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew whether the limits worked.
    So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water temperatures. “There are two ways to save the Atlantic bluefin tuna—protect them in their production grounds and in their feeding grounds,” Prof. Block said. “This will need immediate action in both the central Atlantic, to reduce the loss of the big fish while hunting, and in the Gulf of Mexico and Mediterranean, where tuna produce as separate populations. ”
    小题1: The bluefin tuna in this passage mainly refers to the one _______.
    A．in the AtlanticB．in the Pacific
    C．in the Gulf of MexicoD．in the Mediterranean
    小题2:Which of the following is NOT true according to this passage?
    A．The bluefin tuna is a kind of large and heavy fish.
    B．The number of the bluefin tuna in the sea is getting smaller and smaller.
    C．Scientists are worried about the future of the tuna.
    D．Scientists think that the harvest of the seas will remain good.
    小题3:According to Professor Block, tuna can be saved by ______.
    A．finding a new way to protect them
    B．controlling the catches of them
    C．reducing the population to eat them
    D．protecting them in their production and feeding grounds
    小题4:The purpose of the passage is to ______.
    A．tell people a new way has been found to save the bluefin tuna
    B．call for action to save the bluefin tuna
    C．warn people not to eat tuna sandwiches anymore

    Everyday, 340 million people speak it. One billion people are learning it and it is said that by 2050, half of the world’s population will be using it. What are we talking about? That is the global language—English.
    The English language started in Britain in the 5th century. It is a mixed language. It was built up when German. Scandinavian and French invaders settled in England and created a common language for communication.
    Today it is the official language of the UK, the USA, Australia, New Zealand, Canada, South Africa and Ireland as well as many islands in the Caribbean. Many other countries and regions use it for politics and business, for example, India. Pakistan, Nigeria and the Philippines. English is also one of the official languages of Hong Kong.
    But global advertising and pop music mean that in most countries, you will see or hear some English. Thanks to McDonalds, we all know about “burgers”. “fries” and “milkshakes”. Songs by Madonna, Britney Spears and Celine Dion are in English. We can sing along, even if we do not understand what we are singing!
    English is a messy (杂乱的) language. Every year, dictionaries include new words that talk about popular culture, for example, computer-related words such as "blogging", "download" and "chartroom". Also included are words that teenagers use. Who does not know “cool”, “OK” and “hello”?
    Other languages also influence English. Many English words come from French. Words like “café” and expressions like “c'est la vie” (that is life) are all part of the English language. On the other hand, the French language includes English words like "le weekend" and "le camping". German words are also part of English. Words like "kindergarten" come from the German language.
    Recently, British people have become interested in “yoga”. But the word comes from an ancient Hindu language in India.
    小题1: The English language has a history of ______.
    A．over 2000 yearsB．over 500 years
    C．over 1500 yearsD．over 1000 years

    In a natural disaster—a hurricane, flood, volcanic eruption, or other catastrophes—minutes and even seconds of warning can make the difference between life and death．Because of this, scientists are working to use the latest technological advances to predict when and where disasters will happen．They are also studying how best to analyze and communicate this information once it is obtained．
    On September 29, 1998, Hurricane Georges made landfall in Biloxi, Mississippi, after damaging Haiti, the Dominican Republic, Puerto Rico, and several islands of the Caribbean badly with torrential rains and winds up to 160 km per hour．Few people lost their lives along the Gulf Coast of the United States, although hundreds died in the Caribbean．
    This was a very different outcome from 1900, when a powerful Gulf Coast hurricane made an unexpected direct hit on Galveston, Texas, killing at least 6,000 people．
    Vastly improved hurricane warnings explain the different circumstances at either end of the 20th century——residents of Galveston had no advance warning that a storm was approaching, while residents of Biloxi had been warned days in advance, allowing for extensive safety precautions（预防）．
    At the same time that people in Biloxi were thankful for the advance warning, some residents of New Orleans, Louisiana were less satisfied．A day before Georges made landfall, forecasters were predicting that the hurricane had a good chance of striking New Orleans．Because much of New Orleans lies below sea level, the city is at risk for flooding．Emergency management officials must begin evacuations（疏散）well before a storm strikes．But evacuation costs money: businesses close, tourists leave, and citizens take precautionary measures．The mayor of New Orleans estimated that his city' s preparations for Georges cost more than 50 million．After Georges missed New Orleans, some residents questioned the value of the hurricane forecasts in the face of such high costs．
    The different views on the early warnings for Hurricane Georges show some of the complexities related to predicting disasters．Disaster prediction is a process of providing scientific information to the government officials and other decision makers who must respond to those predictions．
    小题1:What is the purpose of disaster prediction according to the passage?
    A．To identify the cause of disasters．
    B．To save people' s lives and property．
    C．To prevent natural disasters from happening,
    D．To apply advanced technology to disaster prediction．
    小题2:Which of the following areas suffered the most severe damage?
    A．Puerto Rico．B．New Orleans．
    C．Biloxi, Mississippi．D．Galveston, Texas．
    小题3:The city residents of New Orleans were unsatisfied because __  _ .
    A．the forecast hurricane did not hit the city
    B．the hurricane warning arrived rather late
    C．their preparations were made in vain
    D．they suffered from a heavy hurricane attack
    小题4:What does the passage mainly talk about?
    A．The different ways of disaster prediction．
    B．Technological advances in disaster prediction．
    C．The importance and uncertainty of disaster prediction．
    D．The benefits and preparations of disaster prediction．

    To learn an instrument such as the violin or accordion（手风琴）takes years. The job opportunities for musicians are scarce and competition is fierce. Then why are more people than ever before paying a lot of good cash to get their children the best music teaching they can afford?
    The secret lies in the influence of music on the whole person. It has been found that learning a musical instrument actually increases a person’s IQ over time. Different instruments and different trypes of music have varying effect, with classical music and the string family coming out on top, potentially increasing you IQ by up to 12 points!
    When is a good time to start learning music? Experts have found that even the fetus（胎儿）can benefit from listening to classical music. Surround yourself and your family with good music from the first. The Suzuki Piano Method teaches children from the age of 3 years piano, with two lessons per week. From preschool, children can learn to read music and play from sheet music. Progress in learning your instrument is directly proportional（成比例的）to the amount of practicing.
    Is there such a thing as an unmusical child? Shinichi Suzuki proposes that music is the native home language of all human beings and therefore nobody can be “unmusical”. Of course there are exceptional talents, compared to which others may seem to be slower learners.
    Is there any benefit for adults in starting an instrument? Apart from the purely relaxing aspect, yes. Learning an instrument can earn even adults additional IQ points, and as an added benefit in improves your health by reducing your stress levels. Your social life may benefit too, if you are prepared to come out of your box and join occasions such as Ceilidhs (musical get-togethers) or arrange house concerts. It has been established that people who play instruments tend to be more emotionally balanced and more patient with themselves, others and life in general.
    So go ahead, sign up for that amateur orchestra, dust off your old trombone（长号）or take your first real six-string down from the attic（阁楼）; get out there and play!
    小题1:Playing which of the following musical instruments can help increase a person’s IQ most?
    A．The pianoB．The violinC．The tromboneD．The accordion
    小题2:According to Shinichi Suzuki,             .

    “It hurts me more than you,” and “This is for your own good.” There are the statements my mother used to make years ago when I had to learn Latin, clean my room, stay home and do homework.
    That was before we entered the permissive(自由的) period in education in which we decided it was all right not to push our children to achieve their best in school．The schools and the educators made it easy on us．They taught that it was all right to be parents who take a let-alone policy．We stopped making our children do homework．We gave them calculators, turned on the television, left the teaching to the teachers and went on vacation．
    Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing we’ve made a terrible mistake．One such teacher is Sharon Clomps who says of her students—“so passive”—and wonders what has happened．Nothing is demanded of them, she believes．Television, says Clomps, contributes to children’s passivity．“We’re talking about a generation of kids who’ vet never been hurt or hungry．They have learned somebody will always do it for them, instead of saying ‘go and look it up’, you tell them the answer．It takes greater energy to say no to a kid．
    Yes, it does．It takes energy and it takes work．It’s time for parents to end their vacation and come back to work．It’ s time to take the car away, to turn the TV off, to tell them it hurts you more than them but it’ s for their own good．It’s time to start telling them no again．
    小题1:We learn from the passage that the author’s mother used to lay emphasis on（强调：重视）_______．

    Scientists made a great break through this year in England when the first "test tube" baby was born．The birth was the result of many years of research by doctors．The doctors did the research in groups to help the women who cannot conceive a baby in the normal way．
    What happened when the baby was born "from a test tube"? Well, the baby did not literally grow in a test tube．The first stage of the process was that the egg from the woman and the sperm from the man were put together in the test tube．After all, the embryo was put into the womb of a woman．This process was difficult．But it was successful, so the baby was eventually born, like any other, from a woman, only the woman wasn't the baby's real mother, but a sort of "carrier" of a baby produced by another couple．
    Obviously, this method is to help to couples who can't have children because of physical problems in the woman．But very difficult moral problems arise in the kind of situation．Take it for instance, a case that happened this year．A couple who wanted a baby advertised for a woman to have a child by the father of the couple．They offered the woman a lot of money．The woman was made pregnant by artificial insemination; in this case, the woman "employed" to bear the child was its real mother．When the baby was born, the woman refused to give it back to the couple．But, in the eyes of the law, the woman had a right to keep the children because she was its biological mother．
    You could argue that we should change the law to deal with this kind of situation．In earlier times, there were always healthy babies needing adoption, because family planning methods were not so effective as they are now．These days, however, most of the children who can be adopted are over six years old, often handicapped in some way．So a couple who want a young healthy baby cannot always adopt one, this is why the "test tube" baby is in demand．But is it normally right to use this method? Should we temper with nature in this way? Even if we change the law, would this be the right step to take ?
    小题1:The birth of the first "test-tube" baby is a great advance _____．
    A．on medical science
    B．in birth control
    C．on the research for babies
    D．in the lives of married women
    小题2:When we say a baby was born "from a test-tube", we mean_____ ．
    A．the baby didn't develop in the womb of a woman
    B．the baby has no biological parents
    C．the embryo was formed in the test tube
    D．the baby grew in the test-tube before it was born
    小题3:According to the law, who has right to keep the baby produced by the artificial method?
    A．The couple who want a baby．
    B．The biological mother of the child．
    C．The person who pays the money to the real mother．
    D．The father who advertises for a biological mother．
    小题4:According to the passage, people need "test-tube baby" because_____ ．
    A．family planning methods are not effective．
    B．they can't always adopt a young healthy baby
    C．they are unwilling to adopt a child．
    D．there are so many babies needing adoption．

    “People should have one meat-free day a week if they want to make a personal and effective sacrifice that would help deal with climate change,” the world’s leading authority on global warming has told The Observer.
    Dr Rajendra Pachauri, chair of the United Nations Intergovernmental Panel on Climate Change, said that people should then go on to reduce their meat consumption even further.
    Pachauri, who was re-elected the panel’s chairman for a second six-year term last week, said diet change was important because of the huge greenhouse gas emissions (排放) and other environmental problems associated with raising cattle and other animals. “It was relatively easy to change eating habits compared to changing means of transport,” he said.
    The UN’s Food and Agriculture Organisation has estimated that meat production accounts for nearly a fifth of global greenhouse gas emissions. These are produced during the production. For example, ruminants (反刍动物), particularly cows, give off a gas called methane, which is 23 times more effective as a global warming agent than CO2.
    Pachauri can expect some opposite responses from the food industry to his advice, though last night he was given unexpected support by Masterchef presenter and restaurateur John Torode. “I have a little bit and enjoy it,” said Torode. “Too much for any person is bad. But there’s a bigger issue here: where the meat comes from. If we all bought British and stopped buying imported food, we’d save a huge amount of carbon emissions.”
    Professor Robert Watson, the chief scientific adviser for the Department for Environment Food and Rural Affairs, said government could help educate people about the benefits of eating less meat, but it should not regulate. “Eating less meat would help, there’s no question about that,” Watson said.
    However, Chris Lamb, head of marketing for pig industry group BPEX, said the meat industry had been unfairly targeted and was working hard to find out which activities had the biggest environmental impact and reduce them. “Some ideas were contradictory,” he said. “For example, one solution to emissions from cattle and other animals was to keep them indoors, but this would damage animal welfare. Climate change is a very young science and our view is there are a lot of simple solutions being proposed.”
    小题1:What is directly related to global warming?
    A．Consumption of meat. B．Growth of cattle.
    C．Methane from ruminants. D．Processing of meat.
    小题2:Who holds a view opposite to the others’ in the passage?
    A．Rajendra Pachauri.B．John Torode. C．Robert Watson. D．Chris Lamb.
    小题3:It is implied in the passage that _____.
    A．we should try to keep away from cattleB．ruminants should not be left outdoors
    C．the meat industry will soon close downD．we must do our duty to save the earth
    小题4: Which of the following might be the best title for the passage?
    A．Less meat, slower global warming
    B．More animals, more greenhouse gas
    C．Less imported food, better our environment
    D．Greater diet change, smaller climate change

    About 45 percent of Americans don’t get enough sleep, according to a recent survey. However, the benefits of getting enough sleep far outweigh the thrill of watching TV for one more hour or surfing the web. Getting a better night’s sleep will help you lose or keep your weight more effectively. Try these simple steps to improve your quality of sleep.
    Take time to relax
    So many of us go-go-go until it’s time for bed, but it’s important to take time to slow down and relax before sleeping. Do relaxing things, such as listening to soothing (抚慰的) music or deep breathing. Avoid stimulating (刺激的) activities such as writing e-mails, talking on the phone and watching TV. Some guidelines (指导方针): no e-mail after 8 p.m. and no TV or phone calls after 9 p.m..
    Darker is better
    Your body regulates your sleep cycle in response to the presence and absence of light, so dim the lights as evening approaches. Try getting ready for bed by candlelight. When you’re ready to sleep, make sure your room is as dark as possible.
    Put your thoughts to bed
    We all need time to process our day, but bed is not the place to do it if you want to sleep well. Take 10 to 15 minutes to record your thoughts in a journal. This effective technique will capture what’s in your mind so you don’t lie awake. Tell yourself you’re putting your thoughts to bed so that you can go to bed.
    No sugar or alcohol before bed
    These may wake you up. If you need a snack before bed, make it protein.
    Try to get more sleep
    Get an extra hour or two of sleep every night for a week and see how you feel. You’ll notice the difference!
    小题1:The purpose of writing this text is to ________________________.
    A．share some ways to slow down and relax before sleeping

    Old age may not sound exciting.But recent findings offer good news for older pepole and for people worried about getting older.
    Researches found that people become happier and experience less worry after they reach the age of fifty.In fact,they say by the age of eighty—five,people are happier with their life than they were when they were eighteen years old.
    The findings came from a survey of more than 340,000 adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time,the people were between the ages of eighteen and eighty—five.The searches asked questions about emotions like happiness,sadness and worry.They also asked about mental or emotional stress.
    Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults  between the ages of twenty—two and twenty—five.The findings showed that stress levels dropped sharply after people reached their fifties.Happiness was highest among the youngest adults and those in their early seventies.The people least likely to report feeling negative emotions were those in their seventies and eighties.
    The study also showed that men and women had similar emotional patterns as they grew older.Hower,women at all ages reported more sadness,stress and worry than men.Researchers say they do not know why happiness increases as people get older.One theory is that,as people grow older,they grow more thankful for what they have and have better control of their emotion .They also spend less time thinking about bad experiences.
    The researchers also considered possible influences like having young children,being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well—being related to age.
    小题1: How did the researchers find older people happier?
    A．They did a series of experiments.
    B．They made a written survey about the old people.
    C．They interviewed people of different ages face to face.
    D．They telephoned people between the ages of 18 and 85.
    小题2:When do people feel happier according to the passage?
    A．In their twentiesB．In their fifties
    C．After their seventiesD．When they were born
    小题3:Which one is NOT related to the happiness of old people?
    A．Less stressB．Away from working
    C．Controlling of emotionsD．More thankfulness
    小题4:Which is the best title for the passage?
    A．No Worrying about Getting Older
    B．Older Men are Happier than Older Women
    C．The Factors Affecting the Happiness of Old people
    D．For Lots of people,Getting Older Means Getting Happy
