  • 第1题:

    B

    The world is not only hungry,it is also thirsty for water. this may seem strange to you,since nearly 75% of the earth is covered with water. But about 97% of this water is sea water.Man can only drink and use the other 3% fresh water that comes from rivers,lakes,under-ground and other places. And we cannot even use all of that,because some of this fresh water has been made dirty.

    At the moment,this small amount(数量) of fresh water is still enough for us. However,our need for water is getting greater and greater. Only if we take steps to solve this problem now,we can get away from a serious world water shortage later on. The people of the world cannot have an enjoyable life without enough clean water.

    On one hand we should stop wasting this little water of ours,on the other hand we should find ways to reuse it,but this has not been done widely.

    Today,in most large cities,water is used only once and it then returns to the sea or runs into underground places.lf we can make it clean again,it can be used once more just as if it were fresh from a spring.

    But even if large cities reuse its water,we still would not have enough in the future. Where.could we turn to next for water? To the ocean! How can we do to make use of this great a-mount of sea water? We can take the salt from the water to make it fresh.

    So if we take all these steps,we'll be in no danger of drying up!

    ( )26. Why does the writer say that the world is thirsty for water?

    A. The amount of fresh water is really very small.

    B. The people of the world waste too much water.

    C. The people of the world have to drink a lot of water every day.

    D. There are too many people in the world needing water.

    Europa's Watery Underworld

    Europa,one of Jupiter's 63 known moons,looks bright and icy on the surface.But appearances can be
    deceiving:Miles within its cracked,frigid shell,Europa probably hides giant pools of liquid water. Where
    scientists find liquid water,they hope to find life as well.
    Since we can't go diving into Europa's depths just yet,scientists instead have to investigate the moon's
    surface for clues to what lies beneath.In a new study,scientists investigated one group of strange ice patterns
    on Europa and concluded that the formations mark the top of an underground pool that holds as much water
    as the U.S.Great Lakes.
    Pictures of Europa,which is slightly smaller than Earth's moon,clearly show a tangled,icy mishmash
    of lines and cracks known as"chaos terrains".These chaotic places cover more than half of Europa. For
    more than 10 years,scientists have wondered what causes the formations.The new study suggests that they
    arise from the mixing of vast underground stores of liquid water with icy material near the surface.
    For scientists who suspect that Europa also may be hiding life beneath its icy surface,the news about
    the new lake is exciting.
    "It would be great if these lakes harbored life,"Britney Schmidt,a planetary scientist who worked on
    the study,told Science News."But even if they didn't,they say that Europa is doing something interesting
    and active right now."
    Schmidt,a scientist at the University of Texas at Austin,and her colleagues wanted to know how chaos
    terrains form.Since they couldn't rocket to Europa to see for themselves,they searched for similar forma-
    tions here on Earth.They studied collapsed ice shelves in Antarctica and icy caps on volcanoes in Iceland.
    Those features on Earth formed when liquid water mixed with ice.The scientists now suspect something
    similar might be happening on Europa:that as water and ice of different temperatures mingle and shift,the
    surface fractures.This would explain the jumbled ice sculptures.
    "Fracturing catastrophically disrupts the ice in the same way that it causes ice shelves to collapse on
    Earth,"Schmidt told Science News.She and her team found that the process could be causing chaos terrains
    to form quickly on Europa.
    The new study suggests that on this moon,elements such as oxygen from the surface blend with the
    deep bodies of water. That mixture may create an environment that supports life.

    The strange ice patterns on Europa are formed as a result of a mixture of liquid water and solid material underground water pool.
    A:Right
    B:Wrong
    C:Not mentioned

    答案:B
    解析:
    由文章第二段第二句“In a new study...the formations mark the top of an underground pool that holds as much water as the U.S.Great Lakes.”可知,科学家通过研究一组奇异的冰的图案 得出结论:这种结构是一个地下水库的顶部,这个水库的蓄水量相当于美国五大湖的蓄水量, 故选A。
    由文章第三段最后一句话“The new study suggests that they arise from the mixing of vasi underground stores of liquid water with icy material near the surface.”可知,欧罗巴(Europa)上的 奇异冰图案是由大量的含有冰状物质的地下水经混合而成的,故选B。
    由文章第一段的内容可知,欧罗巴是已知的木星63个卫星中的一个,但并未提及其被 发现的早晚,故选C。
    由文章第三段的第乙句话中“Europa , which is slightly smaller than Earth ' s moon”可知, 欧罗巴比地球的卫星―月亮稍微小些,故选B。
    由第六段的第二句话中“Since they couldn ' t rocket to Europa”可知,科学家目前还不能 去欧罗巴星球,故选B。
    由文章第六段的内容可知,Schmidt及其同事在地球上寻找相似的结构进行研究。他 们研究了南极的冰架,认为他们得出的结论也可以解释欧罗巴上的冰形图案,故选B。
    由文章第一段最后一句话的内容可知,科学家们认为有水的地方就很有可能存在生 命;最后一段也提到,欧罗巴星球表面的氧元素和地下水的化合,给生命的出现提供了环境,因 此水的存在是生命出现的必要条件。故选A。

    【录音原文】
      Did you know that there is a kind of bird that can sew? This bird, called the tailorbird, uses its mouth as a needle. It sews leaves together in the shape of a cup. Then it adds a layer of straw to the inside of the cup and lays its eggs there. Each bird species builds its own special kind of nest. The most common materials used for nests are grasses, branches and feathers. A bird must leave these materials into a nest. Just imagine building a house without cement or nails to hold together! Another bird is called the weaverbird. The weaverbird builds a nest that looks like a basket. The nest is shaped like a pear with a hole in the middle. The hole is the door of the nest. A third bird is called the ovenbird. The ovenbird makes a nest that is very solid. The nest is made of mud. The ovenbird forms the mud into the shape of an oven and then lets it dry in the sun. The sun bakes the mud, making it very hard. Not all birds make their homes in branches. Some birds build their nests on the ground, while others bury their eggs under the ground. And some birds do not build nests at all. So when you look for nests and eggs in the branches of trees and bushes, remember that some nests may be right under your feet.
    Questions 1 to 4 are based on the passage you have just heard.
    1. What does the nest built by a tailorbird look like?
    2. Why is there a hole in the weaverbird’s nest?
    3. What is the ovenbird’s nest made of?
    4. What might surprise us about bird’s nests according to the speaker?

    问答题
    Directions:  Please write an essay in about 150 words entitled “Water Shortage” based on the following outline. The first sentence has been given.   Outline:  (1)Water shortage has become much more serious than before.   (2)The chief reasons for water shortage.  (3)My suggestions.

    正确答案:
    Water shortage has become much more serious than before. According to the statistics. 2.2 billion people in 62 countries are facing the shortage of fresh water in the world; there is 300 million people in 26 countries are severely short of water. It is expected that other eight countries will join the 26 countries for severely lacking water in 2010 and 2.7 billion people around the world will face the problem of severe water short-age in 2025.
    The chief reason for water shortage is the low efficiency of water using. As we can see, some water can be reused. For example, we can use the water that we have used to wash clothes, to rinse the toilet. As statistics show, one ton of water will be used while one ton of paper is produced. But with the use of recycled water, the consumption of water can be reduced to half ton. Obviously, with the use of recycled water, the water use efficiency will increase, thus a great lot of water can be saved. But unfortunately, in most of the countries, many companies, particularly in some industries that consume masses of water every day, such as paper making and steel making, haven’t built up their recycle system of water. Lots of water is directly drained without recycling everyday.
    So how to build up more recycle system of water has become most pressing business that can solve the water shortage problem.
