    题目列表(包括答案和解析)

    A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury (埋葬) it in the garden and wait for it to flower（开花）. A biodegradable (生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage users to recycle. Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any poisonous（有毒的）chemicals. British researchers used the new material to develop a phone cover that includes a sunflower seed .When this new type of cover turns into waste, it forms nitrates (硝酸盐). These feed the seed and help the flower grow. Engineers have designed a small transparent (透明的) window to hold the seed. They have made sure it only grows when the phone is thrown away. “We’ve only put sunflower seeds into the cover so far. But we are working with scientists to find out which flowers would perform best. Maybe we could put roses in next time.” said one scientist.
    As phone technology is developing so quickly, people are constantly（不断）throwing their mobiles away. This means producers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can change this, according to the scientists.
    根据短文内容，从题中所给的A、B、C、D四个选项中，选择最佳答案。（10分）
    小题1: After you have finished using the new type of mobile phone, _______.
    A．the phone will do harm to the environment
    B．the phone cover will break down easily in the soil you bury it
    C．it will be recycled by the producers
    D．it can be sent back to the shops.
    小题2: Which of the following is wrong about the cover of the new type of phone?
    A．It can help the sunflower seed after the mobile phone breaks down.
    B．It looks like normal plastics but it can break down.
    C．It includes a sunflower seed.
    D．It makes sure the seed only grows after the phone is thrown away.
    小题3:The new type of phone can reduce the harm to the environment mainly ______.
    A．because of the material of its cover
    B．because of the sunflower seed
    C．because it’s made of no poisonous chemicals
    D．because you bury it in the soil after you finish with it
    小题4: This type of research is done because ________.
    A．the technology that produces mobile phones is changing quickly
    B．users are constantly throwing their mobiles away
    C．nobody has ever thought of recycling mobile phones
    D．producing mobile phones uses a lot of energy, so this has become a very big problem for the environment
    小题5:We can guess from the story ________.
    A．the new type of mobile phones is already on the market
    B．the new type of mobile phones will sell very well
    C．recycling mobile phones is not useful to the environment
    D．other flowers may be used in the new type of mobile phones

    Nowadays, as the society develops, the need of fuel is getting larger and larger. How can we get more and cheaper fuel? One company in New Jersey is developing a special way to get low-cost bio-fuels（生物燃料）from sugar, an importang part for getting ethanol (乙醇).

    In order to make bio-fuels cheaper, the company called Proterro, is trying to cut the cost of making sugar. The company is getting photosynthetic microorganisms (光合微生物) to produce large amounts of sugar, and it is designing a special way to grow the microorganisms using small amounts of water.

    photosynthetic microorganisms, such as algae（藻类）, are usually thought that it can produce oils. Proterro paid so much attention to making sugar because bio-fuel ethanol is mainly from it, and it’s also the starting point for new ways of making other types of bio-fuels.

    Today, almost all of the sugar for bio-fuels is made from corn or sugarcane（甘蔗），and several companies are trying more ways to make sugar from other plants such as grass and trees. “But we’ve just got the beginning to make bio-fuels; sugar is still expensive,”says Kef kasdin, Proterro’s CEO. Only sugar from sugarcane is cheap enough, and that can only be grown inexpensively in some places, such as Brazil.

    51. Why do people try to make bio-fuels?

    A. The usual fuels are getting more and more.            

    B. Bio-fuels are more important than the usual fuels.    

    C. The usual fuels are getting cheaper.

    D. Bio-fuels are cheaper than the usual fuels.

    52. How are people trying to make bio-fuels cheaper?

    A. By making more bio-fuels.         

    B. By cutting the cost of making sugar.

    C. By getting more photosynthetic microorganisms.

    D. By using small amouts of water.

    53. Which of the followings might NOT be used to make bio-fuels

    A. Wheat         B.Sugarcane         C. Corn             D.Glass

    54. How many types of bio-fuels have been made according to the passage?

    A. One           B.Two               C. Three            D.Four

    55. What do Kef kasdin’s words mean?       .

    A.Making bio-fuels has become quite easy.

    B. Bio-fuels may be a little more expensive.

    C. The company hasn’t cut the cost low enough yet.

    D. The company can only get sugar from sugarcane now.

    Living in a foreign culture can be exciting, but it can also be confusing(令人迷惑的). A group of Americans who taught English in other countries recently discussed their experiences. They decided that miscommunications(沟通误解)were always possible, even over something as simple as “yes” and “no”.
    On her first day in Micronesia, an island in the Pacific(太平洋), Lisa thought people weren’t paying any attention to her. The day was hot. She went into a store and asked, “Do you have cold drinks?” The woman there didn’t say anything. Lisa repeated the question. Still the woman said nothing. She later learned that the woman had answered her: She had raised her eyebrows(眉毛)，which in Micronesia means “yes”.
    Jan remembered an experience she had in Bulgaria, a country in Europe. She went to a restaurant that was famous for its cabbage. She asked the waiter, “Do you have cabbage today?” He nodded his head. Jan waited, but the cabbage never came. In that country, a nod means “no”.
    Tom had a similar problem when arrived in India. After explaining something in class, he asked his students if they understood. They answered with many different nods and shakes of the head. He thought some people had not understood, so he explained again. When he asked again, they did the same thing. He soon found out that his students did understand. In India, people nod and shake their heads in different ways depending on(依据)where they come from. You have to know where a person is from to understand whether they mean “yes” or “no”.

    A．should go abroad for vacations
    B．needed to learn foreign languages
    C．should often discuss their experiences
