    E
    Almost every day we come across situations in which we have to make decisions one way or another. Choice, we are given to believe, is a right. But for a good many people in the world. In rich and poor countries, choice is a luxury, something wonderful but hard to get, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, a false idea created by companies and advertiser, hoping to sell their products.
    The endless choice gives birth to anxiety in people’s lives. Buying something as basic as a coffee pot is not exactly simple. Easy access to a wide range of everyday goods leads to a sense of powerlessness in many people, ending in the shopper giving up and walking away, or just buying an unsuitable item(商品) that is not really wanted. Recent studies in England have shown that many electrical goods bought in almost every family are not really needed. More difficult decision-making is then either avoided or trusted into the hands of the professionals, lifestyle instructors, or advisors.
    It is not just the availability of the goods that is the problem, but the speed with which new types of products come on the market. Advances in design and production help quicken the process Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The typical example is computers, which are almost out-of-date once they are bought. This indeed makes selection a problem. Gone are the days when one could just walk with case into a shop and buy one thing; no choice, no anxiety.
    【小题1】 What does the author try to argue in Paragraph 1?

    A．The exercise of rights is a luxury.
    B．The practice of choice is difficult.
    C．The right of choice is given but at a price.
    D．Choice and right exist at the same time.
    【小题2】 Why do more choices of goods give rise to anxiety?
    A．Professionals find it hard to decide on a suitable product.
    B．People are likely to find themselves overcome by business persuasion.
    C．Shoppers may find themselves lost in the broad range of items.
    D．Companies and advertisers are often misleading about the rage of choice.
    【小题3】By using computers as an example, the author wants to prove that    .
    A．advanced products meet the needs of people
    B．products of the latest design fold the market
    C．competitions are fierce in high-tech industry
    D．everyday goods need to be replaced often
    【小题4】 What is this passage mainly about?
    A．The variety of choices in modern society.
    B．The opinions on people’s right in different countries
    C．The Problems about the availability of everyday goods.
    D．The helplessness in purchasing decisions

    “I usually put my mobile phone in my bag, and I often feel like it is ringing when there actually is no phone call. Now I always want to keep it in my hand, being afraid that I might miss important calls or messages,” Miss Liu tells her doctor.
    Miss Gu, a news worker, has to take her mobile phone with her all the time so as not to miss any calls from her office or readers. Gradually, she started to experience a great “panic” about her mobile phone. “Every night when I’m about to fall asleep, I often wake up with a start, feeling that my phone is ringing. Although I’m sure that I have turned it off, I still feel that it is ringing, clearly.”
    The above phenomenon is what we call “mobile-phone acouasm (幻听)”. The mobile phone has now become a “new organ” in a white collar’s daily life, and “mobile-phone acouasm” has become a common phenomenon among office workers.

    “You know that the rings are not from your phone, but you always take it out and have a look. This is subconscious (潜意识) from your body sending you a signal, telling you that you must take a break to reduce your pressure,” Professor Sun Li from Huadong Normal University explains.
    There are many ways to solve the problem. The professor says that the key is to deal with pressure from work. “This is just a kind of self-protection”; the most important thing is to find out the source of your pressure. And then take part in some activities that are not related to your work. You can do anything that can relax your body and mind.
    【小题1】 According to the passage the phrase “mobile-phone acouasm” refers to          .

    A．people’s being addicted to mobile phones
    B．people’s feeling the unreal phone rings

    B．Some people develop the dependency on mobile phones.
    C．Some people listen to the music on mobile phones too much.
    D．Something is wrong with some people’s hearing.
    【小题3】What kind of people are more likely to suffer from “mobile-phone acouasm” ?
    A．Those who use mobile phones too often.
    B．Those who like mobile phones very much.
    C．Those who lead a busy life.

    D．To have your ears examined regularly.

    Say you meet with difficulty, what’s the first thing you do? Call your best friend and ask for help? It turns out that doing this may be better for you than you think. Researchers find that friendship has a big influence on your health, well-being and business.

    One study from scientists recently found that older people with a large circle of friends were 22% less likely to die during a 10-year period than those with fewer friends. Other researchers discovered that having a strong social network could improve brain health as we age.

    Even more interesting, feeling close to your friends may give you a different view on things. Researchers gathered 34 college students out side and asked them to estimate the steepness(估计陡峭程度) of a hill after climbing it. Those standing with friends gave lower estimates, and the longer the friends had known each other, the less steep the hill appeared.

    What is the reason that friends can make obstacles seem less difficult? “People with stronger friendship networks feel that there is someone they can turn to,” said Karen A. Roberto, director of the center of the hospital at Virginia Tech. “Friendship is a valued resource (宝贵的资源).”

    It is truly the fact. Friends make your life better. They provide support in hard times. They inspire you to make changes in your life, encourage you to set goals and cheer you on every step of the way until you reach them.

    With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills（泄露） on people, nature, and the environment．

        Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil．Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea．

        Of all of today’s environmental disasters, an oil spill may actually be one of the least serious．Although oil is poisonous, it is a natural material．In the end, it breaks down naturally．There are, of course, long-term effects, but it is usually more serious in the short term．

        Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible．In 1967 the tanker Torrey Canyon sank off the Sicily Isles near the coast of England and spilled 120,000 tones of oil into the ocean．If you go there today, you will find it hard to see any sign that it ever happened．

        Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage．Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!

    We should be thinking more about reducing our dependency on oil．Governments should be encouraging research into new technologies, such as cars run by solar power（太阳能）, electricity, hydrogen, and so on．Much of this research has, in the past, been held back by the oil, gas, and coal．

    If the world’s millions of cars were 10% more efficient（高效的）— and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year．If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too．

    1.What is the passage mainly talking about?

        A．Oil tanker accidents．           B．Oil spills pollution．

        C．What oil pollution is．          D．How to reduce oil pollution．

    2.How does the author support the idea that oil spills are not as serious as people believe?

        A．By giving a description．        B．By making an argument．

        C．By giving an example．           D．By drawing a diagram．

    3.What does the underlined word “risk” in Paragraph 5 refer to?

        A．Transportation depending more on oil．

        B．Poisonous oil breaking down naturally．

        C．Millions of tons of oil spilling into the sea．

        D．More environmental damage being caused．

    4.Which suggestion is made for reducing oil tank accidents according to the passage?

        A．We should develop new technologies to cut oil use 

    B．Tankers should not be allowed to sail near the coastlines．

        C．We should build safer oil tankers in the near future．

    D．Countries should build more oil pipelines under the sea．
