    The UN Environment Programme says that rising temperatures could mean the end for some migrating animals.
    Migrating or mobile animals move through several environments as they travel away from the cold of winter to warmer areas. Birds may fly from one part of the world to another, perhaps stopping at feeding grounds on the way. Whales and turtles (海龟) cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm. "Obviously these animals have developed their travelling patterns over thousands of years. But climate change is almost certain to be extreme over the next 25 to 50 years and it is extremely unlikely that these animals can change their habits fast enough," said the report author Dr Robert Hepworth.
    Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures, turtles produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only females, the report says. It also provides evidence that some turtles are more likely to develop cancer as the waters get warmer.
    With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of climate-related changes including rising sea levels, land loss and more violent storms, the report concludes.
    Other animals picked out as particularly in danger include:
    · the North Atlantic Right Whale, whose main food (tiny shrimp) is disturbed by the change in ocean flows and
    · the White-Nose Dolphin, which is out-competed by other kinds of dolphins in warmer waters.
    The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover. "We need governments to start taking action at the national and international lever. “The clock is running.” said Dr Hepworth. And some animals are already adapting, with the report mentioning whales that are changing their feeding behaviour, finding new feeding grounds and new foods to eat.
    小题1:What is the main topic of the text?
    A．The effect of climate change on migrating animals.
    B．How animals are adapting to changes in temperature.
    C．The actions required to save migrating animals.
    D．The need for government policies to prevent global warming.
    小题2:By saying "the clock is running" in the last paragraph, Dr Hepworth means that “_______”.
    A．it may be too late to save some animals
    B．it is time to start protecting the animals
    C．there is not much time to solve the problem
    D．it takes time to complete the actions
    小题3:According to the report, how will global warming affect turtles in the future?
    A．They will only produce female babies.
    B．Their food supply will gradually disappear.
    C．Some will suffer from higher rates of cancer.
    D．They will be in greater danger because of more violent storms.
    小题4:Which of the following is mentioned as a consequence of rising temperatures?

    B．20 percent of all birds are likely to die out because of land loss.
    C．Migrating animals are likely to start adapting to the changes more quickly.
    D．Warmer oceans will increase the competition between different kinds of dolphins.

    Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier，have better marriages and have more respectable occupations. Personal consultants give them better advice for finding jobs. Even judges are softer on attractive defendants(被告)．But in the executive circle，beauty can become a liability.
    While attractiveness is a positive factor for a man on his way up the executive ladder，it is harmful to a woman.
    Handsome male executives were thought as having more integrity than plainer men；effort and ability were thought to account for their success.
    Attractive female executives were considered to have less integrity than unattractive ones；their success was attributed not to ability but to factors such as luck.
    All unattractive women executives were thought to have more integrity and to be more capable than the attractive female executives. Interestingly，though，the rise of the unattractive overnight successes was attributed more to personal relationships and less to ability than that of attractive overnight successes.
    Why are attractive women not thought to be able？An attractive woman is thought to be more feminine and an attractive man more masculine(有男子气概的)than the less attractive ones. Thus，an attractive woman has an advantage in traditionally female jobs，but an attractive woman in a traditionally masculine position appears to lack the “masculine” qualities required.
    This is true even in politics. “When the only clue is how he or she looks，people treat men and women differently，”says Anne Bowman，who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduate students to rank two groups of photographs，one of men and one of women，in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again，in the order they would vote for them.
    The results showed that attractive males utterly defeated unattractive men，but the women who had been ranked most attractive invariably received the fewest votes.
    小题1:The underlined word “liability”(in Para.1)most probably means “________”．
    A．misfortuneB．instabilityC．disadvantageD．burden
    小题2:In traditionally female jobs，attractiveness________.
    A．reinforces(加强)the feminine qualities required
    B．makes women look more honest and capable
    C．is of primary importance to women
    D．often enables women to succeed quickly
    小题3:Bowman's experiment reveals that when it comes to politics，attractiveness________.
    A．turns out to be an obstacle to men
    B．affects men and women alike
    C．has as little effect on men as on women
    D．is more of an obstacle than a benefit to women
    小题4:It can be inferred from the passage that people's views on beauty are often________.
    A．practicalB．prejudicedC．old­fashionedD．pessimistic
    小题5:The author writes this passage to________.
    A．demand equal rights for women
    B．emphasize the importance of appearance
    C．discuss the negative aspects of being attractive
    D．give advice to job­seekers who are attractive

    Most people believe they don't have imagination. They are wrong. Everyone has imagination, but most of us，once we became adults, forget how to access it. Creativity isn't always connected with great works of art or ideas. People at work and in their free time routinely think of creative ways to solve problems. Maybe you have a goal to achieve，a tricky question to answer or you just want to expand your mind! Here are three techniques to help you.
    This technique involves taking unrelated ideas and trying to find links between them. First，think about the problem you have to solve or the job you need to do. Then find an image，word，idea or object，for example，a candle. Write down all the ideas/words associated with candles：light，fire，matches, wax，night，silence，etc. Think of as many as you can. The next stage is to relate the ideas to the job you have to do. So imagine you want to buy a friend an original present; you could buy him tickets to a match or take him out for the night.
    　  Imagine that normal limitations don't exist. You have as much time/space/money，etc. as you want. Think about your goal and the new possibilities. If，for example，your goal is to learn to ski, you can now practice skiing every day of your life (because you have the time and the money). Now adapt this to reality. Maybe you can practice skiing every day in December，or every Monday in January.
    Look at the situation from a different point of view. Good negotiators use this technique in business，and so do writers. Fiction writers often imagine they are the characters in their books. They ask questions: what does this character want? Why can't she get it? What changes must she make to get what she wants? What does she dream about? If your goal involves other people, put yourself “in their shoes”. The best fishermen think like fish!
    小题1:According to the passage, when we become adults, _________ .
    A．most of us are no longer creativeB．we can still learn to be more creative
    C．we are not as imaginative as childrenD．we are unwilling to be creative
    小题2:The second technique suggests that you just imagine
    A．setting a goal is as simple as skiing
    B．new possibilities will soon appear
    C．December and January are the best months for skiing.
    D．you have every resource to achieve your goal
    小题3:The phrase “put yourself in their shoes” in paragraph 4 is closest in meaning to ______  .
    A．dress yourself like themB．think as they would
    C．do as they ask you toD．put on their shoes
    小题4:We learn from the third technique that a good salesman should ask himself “ _________ ?”.
    A．what do I usually doB．what did my boss tell me to do
    C．what are my customers' needsD．how should I sell my products

    It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other parts.
    　　The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
    　　And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.
    小题1:The first paragraph tells us that _____.
    A．all living things in nature depend on each other
    B．everything in nature can’t exist without the help of man
    C．man has known the importance of the balance of nature for a long time
    D．no living thing can live naturally
    小题2:In the second paragraph the examples given are used to prove that _____.
    A．all forms of life belong to a system in which all the parts can be changed for one another
    B．it is only during the last few years that man has generally known the balance of nature
    C．there are some living things which can exist by themselves without change
    D．we can’t change one form of life without destroying the balance of nature
    小题3:The last paragraph suggests that in order to get his immediate benefits(利益) _____.
    A．man is always anxious to control his activities within limits
    B．man is always too eager in planning for distant future
    C．man often fails to think about their future results of his action
    D．man often feels that he will have to give up in despair
    小题4:Which of the following is true according to the passage?
    A．Cutting down woods does little harm to human beings.
    B．Man has to pay much more attention to the future results of his present action.
    C．Oxygen comes from forests.
    D．The passage tells us to try our best to get as much as possible immediately.

    Everyone is at it, even my neighbors. I thought I might be the only person left in the world who hadn’t done an eBay deal. So, I decided to try my hand at online auction (网上拍卖).
    Buying for beginners: Sign up on www. ebay. co. uk. Most items（e.g. tables, computers, and books）ready for auction will come with a picture and a short description; others may be marked with “ Buy It Now ” and have a fixed price. You can buy these right away.
    If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids（出价）for you. The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and asked if you would like to bid again. Auctions last up to 10 days and when they finish you get an email telling you whether you have won the item.
    How to pay: Sellers decide how they would like to be paid and you need to check this before placing a bid as you might not want to post a check or postal orders. The easiest way is through PayPal, an online payment system that takes the money away from your credit card (信用卡).
    Selling made simple: If you plan to sell on eBay, it helps to include a picture of the item. I followed my friends’ advice and put up the items I wanted to sell for a 10-day auction, starting on a Thursday. This way buyers had two weekends to bid.
    The big things in life: It’s easy to post a small item, but furniture is a big part of eBay and this has to be collected or sent by delivery men. Check the ways of delivery before you bid.
    小题1:What is the passage mainly about?
    A．How to make payment online.
    B．Ways of using delivery online.
    C．Advantages of an online-auction system.
    D．How to use an online-auction system.
    小题2:After bidding for an item, a buyer __________.
    A．will get what he wants in ten days
    B．should make payment immediately
    C．has chances to make higher bids
    D．may check its picture and description
    小题3:The easiest way of making payment mentioned in the passage is __________.
    A．through an online payment system
    B．through a local banking system
    C．by sending the money to the seller
    D．by paying the deliveryman directly

    With the Tesla Roadster and other plug­in (插入式) electric vehicles hitting the road，demand is growing for accessible refueling points to recharge them. Carbon Day Automotive, a Chicago­based company，has now demonstrated a solar­powered recharging point, known as the Solar Plug­In Station，which lets motorists easily charge their cars using electricity that has been produced without any environmental damage.
    The Solar Plug­In Station has gone on show in Chicago as part of the city’s bid to host the 2016 Olympic Games. According to Carbon Day Automotive，the Solar Plug­In Station on show in Chicago is part of the vital infrastructure(基础设施) required for electric vehicles in Chicago and was the focus of a recent visit by the International Olympic Committee.
    These solar­powered electricity points will be used daily to fuel the city’s electric vehicles with power from the sun. By producing the electricity from pollution­free solar cell, the CO2 emissions are reduced to zero.
    “Solar energy and electric vehicles are a partnership that is one more step to reducing our dependence on foreign oil,” says Richard Lowenthal, CEO of Coulomb Technologies.Coulomb Technologies recently developed the components (部件) required for individual recharging stations，marketed as ChargePoint Networked Charging Stations.Carbon Day Automotive is the Midwest distributor for the ChargePoint stations. The Solar Plug­In Station consists of giant solar panels (电池板) that shade the tiny ChargePoint Networked Charging Station.The solar panel is connected to an underground battery pack，ready for everyday refueling.
    “Without these stations it would be like driving around in a traditional car without the availability of gas stations，” says Scott Emalfarb，CEO at Carbon Day.“The day of true plug­in electric vehicles will be here sooner than most people realize and the world needs to be ready to accommodate them.”
    小题1:The Solar Plug­In Station is used as part of the bid to host the Olympics mainly because ________.
    A．it’s environmentally friendly
    B．it makes up for the lack of electricity
    C．it’s a new idea and attracts people’s attention

    Light for the City
    Edison and his assistants came to New York to set up an electric power system. They hoped it would provide enough electricity to light up a part of the great city.
    They bought several machines with them. These were called generators(发电机), which produced electricity power for lamps in Edison’s building.
    Soon there were lights for the building. Edison lived in a room facing the street and he often worked over night. The light burned brightly and steadily and he often worked over night. People often came and stopped their horse-drawn carriage to look. Everyone knew that Thomas Edison was in town.
    First, the inventor and his assistants produced several large generators. A great deal of power would be needed to light up even a small part of the city. Then the workers were busy digging deep trenches in the hard earth below the city streets, and Edison had fourteen miles of wire laid into the trenches. The wire connected each building to a generator.
    Setting up an electric power system was not an easy job. It took a year and a half. In September, 1882, the job was finished.
    A small group of men stood around Edison inside the power house. The big moment came at last. The inventor, taking a deep breath, pulled a switch. The electric lights flashed up.
    “Very good! Very good!” a man nearby shouted to praise Edison for what he had done.
    “Sir,” said Edison, “this is only the beginning!” And Edison was right. Soon Edison’s lamp were lighting up cities all over the world.                
    小题1:The generators they brought with them could produce as much as electricity as ______ needed.
    A．Edison’s buildingB．a small part of the city
    C．the whole cityD．the world
    小题2:Trenches were dug to ______.
    A．set up generatorsB．lay wiresC．built city streetsD．build a power house

    B．produce several large generators
    C．dig the deep trenches
    D．lay fourteen miles of wire into the trench
