    Every pet owner loves his pet. There is no argument here.
    　　But when we asked our readers whether they would clone （克隆， 复制）their beloved animals, the responses（反应） were split almost down the middle. Of the 228 readers who answered it, 108 would clone, 111 would not and nine weighed each side without offering an opinion.
    　　Clearly, from readers’ response, this is an issue that reaches deeply into both the joy and final sadness of owning a pet. It speaks, as well, to people’s widely differing expectations over the developing scientific procedure.
    　　Most of the respondents who favored the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope a clone could never truly recreate a pet, many simply didn’t wish to go against the natural law of life and death.
    　　Both sides expressed equal love for their animals. More than a few respondents owned “the best dog/cat in the world”. They thought of their pets as their “best friend”, “a member of the family,”“the light of my life.” They told moving stories of pets’ heroism, intelligence and selfless devotion.
    　　Then the loss is so disturbing---and the cloning so attractive. “People become very close to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of Goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away…It’s understandable. Death is always painful. It’s difficult to deal with. It’s hard to accept.”
    　　But would cloning reduce the blow? This question seemed to be at the heart of this problem.
    小题1:So far as the cloning of pets is concerned, a recent survey shows that, of all pet owners, ____.
    A．a lot more of them are for it
    B．a lot more of them are against it
    C．very few of them are willing to tell their opinions
    D．about half of them are for it and the other half against it
    小题2:While talking about the respondents from the readers, the expression “final sadness of owning a pet” refers to ____.
    A．the death of one’s pet
    B．the high cost of owning a pet
    C．the troubles one has to deal with in keeping a pet
    D．the dangers about the cloning of a pet
    小题3:From what Gary Kowalski says, we can know that he ____.
    A．has never thought about the problem of cloning
    B．is going to write another book on pets
    C．is in favor of the idea of cloning pets
    D．is all against the cloning of pets
    小题4:What is the key question at the heart of the problem of cloning pets?
    A．Can cloning make the pain one suffers less when a pet dies?
    B．Can pet owners afford the cost of cloning?
    C．Does cloning go against the law of nature?
    D．How reliably does cloning produce an exact copy of one’s pet?

    Listening to a radio broadcast in a foreign language is difficult for many of us. We may have studied the language for several years, and are able to read it, perhaps even write in it. But listening and understanding the spoken language require special skills. Some people have a natural ability that helps them to learn a language quickly, while others must study for a long time. Everyone, however, can improve his or her listening skills with practice.
    We are good listeners in our own language because we have had years of practice. We understand the grammar and the language. We know what to expect a person to say to us in almost any situation. We have been in similar situations many times, and we have heard it all before. We can understand it, even if we do not listen carefully.
    But this is not true with a foreign language. We must listen with our full attention. And we must try not to let the cultural style of our language affect our understanding of the foreign language. Listening to a foreign language broadcast is easier if we know something about it. There are clues that can help us. One clue is the time of a day. Morning programs usually contain many short items of news, information or entertainment. The items are short because most of us are getting ready to go to work in the morning. Often we do not have time to listen to long programs. Evening programs are different. There is time for more details about the subjects discussed.
    We can get a clue about the program from the music at the beginning, but we must be familiar with the music of the foreign culture. The kind of music—serious and slow, or fast and light—can tell us what kind of program to expect. The name of the program can give us good information about what it will contain.
    Another good clue is the broadcaster. The more we listen to the same person, the easier it will be to understand him. His speaking style will become familiar to us. Further, the broadcaster provides clues to the organization of the broadcast at the beginning of the program. The broadcaster usually gives us the highlights of the program to prepare us for the details that will follow.
    小题1:We are good listeners in our own language because ________.
    A．we have a natural ability of learning languageB．our own language is much easier
    C．we listen to our own language more carefullyD．we have practiced it for years
    小题2: If you don’t have enough time, you can listen to ________.
    A．evening programs B．programs with soft music
    C．morning programs D．familiar programs
    小题3:You can know the information of the program according to ________.
    A．its music B．the broadcaster
    C．its name D．the time of the program

    When you’re surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers?
    According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letters- to record the computer user’s age, gender, location, favorite movies and hobbies.
    The newspaper reports that Lotame Solutions Inc., a New York company, uses sophisticated(高科技) software called a "beacon" to capture what people are typing on a website.
    Lotame packages that data into profiles（个人资料）about individuals, only without their names, and sells the profiles to companies seeking customers．Batches of such data may be sold for a few dollars.
    The Wall Street Journal survey discovered that spying on Internet users is one of the fastest-growing businesses on the World Wide Web.
    The "cookie"- a tiny text file put on your PC by websites or marketing firms which might be used to remember your preferences for one site, or to track you across many sites is already old news．There are new and more complex tools such as "beacons" which scan in real time what people are doing on a webpage．These beacons instantly assess the Internet user’s location, income, shopping interests and even medical conditions.
    Millions of Internet users around the world also face unprecedented（空前的）threats．Private, sensitive, personal and business information is being gathered and sold without their knowledge.
    Companies insist the information they gather is anonymous and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don’t know that they were installing intrusive files on visitors’ computers．These include MSN.com and Yahoo.com.
    Next time you visit a webpage and find an ad banner advertising something you’ve been planning to buy, don’t be amazed that your computer can read your mind.
    小题1:The purpose of the passage is to          .
    A．introduce a tiny file in a computer-a single code
    B．show how your individual information was let out when you surf the Internet
    C．show how to protect your privacy
    D．introduce a sophisticated software called a "beacon"
    小题2:．All of the following statements are Wrong except          .
    A．Lotame sells the profiles about individuals to companies seeking customers with their age, gender, location, hobbies and names
    B．spying on Internet users is the fastest-growing businesses on the World Wide Web
    C．some of the biggest websites in the US know they were installing intrusive files on visitors’ computers
    D．a tiny file in a computer-a single code consisting of a long series of numbers and letters can record users’ information
    小题3:It can be inferred that          .
    A．because the data is used harmlessly．Internet users around the world will not face threats
    B．when a person surf the Internet, his personal details may be let out without his knowledge
    C．your computer can really read your mind
    D．MSN.com and Yahoo.com．use software to capture what people are typing on a website
    小题4:According to the passage, “beacon”          .
    A．is a tiny text file put on your PC by websites
    B．is a soft ware that can package that data into profiles about individuals
    C．can assess the Internet user’s location, income, shopping interests and even medical conditions
    D．is not more complex than the "cookie"
    小题5:What’s the writer’s attitude to this problem?

    The UK has a well­respected higher education system and some of the top universities and research institutions in the world. But to those who are new to it all， sometimes it can be confusing.
    October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends， join lots of clubs and settle into university life.
    However， having just left the comfort of home and all your friends behind， the prospect(前景) of meeting lots of strangers in big halls can be nerve­wracking(令人头痛的). Where do you start？ Who should you make friends with？ Which clubs should you join？
    Luckily， there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.
    Here are some top advice from past students on how to survive Freshers’ Week：
    ●Learn rules. Make sure you know British social manners. Have a few wine glasses and snacks handy for your housemates and friends.
    ●Be kind. Sometimes cups of tea or even slices of toast can give you a head start in making friends.
    ●Be sociable. The more active you are， the more likely you’ll be to meet new people than if you’re someone who never leaves their room.
    ●Bring a doorstop. Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.

    When Xia Min started drinking alcohol with her classmates at a friend’s birthday, she didn’t realize what would happen to her. She drank a lot and fell into a coma (昏迷). The 15year-old girl from Chongqing never recovered.
    Xia’s death is warning to other students. A new rule went into effect on January 1, 2006. Teens are not allowed to buy or drink alcohol. Shops are not allowed to sell it to them.

    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes. To some extent our intelligence is given us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person's intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
    It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.www.examda.com
    Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays.
    This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.
    小题1:Which of these sentences best describes the writer's point in Paragraph 1?
    A．To some extent, intelligence is given at birth.
    B．Intelligence is developed by the environment.
    C．Some people are born clever and others born stupid.
    D．Intelligence is fixed at birth, but is developed by the environment.
    小题2: It is suggested in this passage that_______.
    A．unrelated people are not likely to have different intelligence
    B．close relations usually have similar intelligence
    C．the closer the blood relationship between people, the more different they are likely to be in intelligence
    D．people who live in close contact with each other are not likely to have similar degrees of intelligence
    小题3:Brothers and sisters are likely to_______.
    A．have similar intelligence B．have different intelligence
    C．go to the same university D．go to the same factory
    小题4:The best title for this article would be_______.
    A．On Intelligence　B．What Intelligence Means
    C．We Are Born with IntelligenceD．Environment Plays a Part in Developing Intelligence

    US researchers have found traces of an ancient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life.
    The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the University of Colorado.
    “This is the first clear evidence of shorelines on the surface of Mars,”said Boulder’ s research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters.
    “The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago.”
    Analysis of the images has shown the water carved out the canyon (溪谷) in which it was found, which then opened out into a valley depositing (使淤积) sediment (沉积) which formed a delta (三角洲).
    “Finding shorelines is a great discovery to us,” said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry.
    Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago.
    The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study.
    Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life.
    小题1:The size of the lake found on Mars is ______.
    A．80 square miles B．1,500 square miles
    C．3.4 billion square milesD．300 million square miles
    小题2:When the lake existed, the weather on Mars was ____.
    A．hot and wet B．wet and warm C．cold and dryD．cold and wet
    小题3:Why do scientists think deltas near the lake may hold secrets about past life on Mars?
    A．Because similar places on Earth have become natural deposits of markers of life.
    B．Because someone has put secrets about past life on Mars there.
    C．Because past life has been found in other deltas on Mars.
    D．Because some people are said to have already seen life marks there.
    小题4:Which of the following statements is NOT true according to the passage?
    A．The Noachan epoch was a wet and warm era.
    B．The lake might have existed 3.4 billion years.
    C．The discovery can’ t fully prove that the Mars once hosted life.
    D．The lake traces prove that there exists life on Mars now.

    LONDON----Here’s a new warning from health experts: Sitting is deadly.
    Scientists are increasingly warning that sitting for prolonged periods — even if you also exercise regularly — could be bad for your health. And it doesn’t matter where the sitting takes place — at the office, at school, in the car or before a computer or TV — just the overall number of hours it occurs. Several studies suggest people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.
    　　In an editorial published this week in the British Journal of Sports Medicine, Elin EkblomBak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting.
    　　While health officials have issued guidelines recommending minimum amounts of physical activity, they haven’t suggested people try to limit how much time they spend in a seated position.
    　　"After four hours of sitting, the body starts to send harmful signals," Ekblom-Bak said. She explained that genes regulating(调节) the amount of glucose（葡萄糖） and fat in the body start to shut down.
    　　Even for people who exercise, spending long periods of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day — but still spend a lot of time sitting — might get more benefit if that exercise were spread across the day, rather than in a single bout.（一回）
    　　Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat more had a higher death risk, independently of whether or not they exercised.
    　　"We don’t have enough evidence yet to say how much sitting is bad," said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge, who led the Canadian study. "But it seems the more you can get up and interrupt this sedentary behavior, the better."
    　　Figures from a U.S. survey in 2003-2004 found Americans spend more than half their time sitting, from working at their desks to sitting in cars.
    　　Experts said more research is needed to figure out just how much sitting is dangerous, and what might be possible tooffset those effects.
    　　"People should keep exercising because that has a lot of benefits," Ekblom-Bak said. "But when they’re in the office, they should try to interrupt sitting as often as possible," she said.
    小题1:What is the best title for the text?
    A．Not Sitting Too Much While WorkingB．How To Avoid Sitting Too Much
    C．Sitting Too Much Could Be DeadlyD．More And More People Sit Too Much
    小题2:According to the research,______________.
    A．the more time you spend in exercising in a single bout, the healthier you will be.
    B．those who often sit too much are sure to grow fat or suffer from a heart attack.
    C．regular exercise is effective to get rid of the side effect of sitting too much.
    D．you had better not sit for more than four hours in a single bout.
    小题3:How does the danger of sitting too much affect the human body?
    A．It results in a higher death risk.
    B．It increases glucose and fat in the body.
    C．It makes a person unable to exercise long enough in a day.
    D．It causes the gene to fail to balance the glucose and fat in the body.
    小题4:In the opinion of Ekblom-Bak, you’d better have a rest in the office by________.
    A．sending your friends e-mails
    B．having a walk around your office
    C．chatting online or playing computer games
    D．listening to music with your head on the desk.
