3.Most of us，when we reached our teens，started looking forward to the day when we would occupy places of our own，far from the confines of our families. We saw this moving away as a chance to strike out on our own，to grow，to spread out wings and experience freedom. At the same time，we regarded this independence as temporary-the thing to do until we found the perfect mate and married. Over the years，many millions of people have made this passage from one family to another，with just a brief，often nervous interval of independence in between. But recently，more and more people have begun to challenge the concept that living together is better than living alone. Being single is now accepted as an alternative lifestyle-one that is natural，rewarding，and complete. In fact，being single has become almost fashionable.

    A Record-Breaking Rover
    NASA's Mars rover Opportunity has boldly gone where no rover has gone before—at least in terms of distance. Since arriving on the Red Planet in 2004,Opportunity has traveled 25 .01 miles,more than any other wheeled vehicle has on another world.
    “This is so remarkable considering Opportunity was intended to drive about 1 kilometer and was never designed for distance,”says John Callas,the Mars Exploration Rover Project Manager.
    He works at NASA's Jet Propulsion Laboratory in Pasadena,California.“But what is really importantly is not how many miles the rover has racked up,but how much exploration and discovery we have accomplished over that distance.”
    The solar-powered Opportunity and its twin rover,Spirit,landed on Mars 10 years ago on a mission expected to last 3 months. The objective of the rovers was to help scientists learn more about the planet and to search for signs of life,such as the possible presence of water.
    Spirit stopped communicating with Earth in March 2010,a few months after it got stuck in a sand pit. But Opportunity has continued to collect and analyze Martian soil and rocks.
    During its mission,Opportunity has captured,and sent back to Earth,some 187,000 panoramic and microscopic images of Mars with its cameras. It has also provided scientists with data on the planet's atmosphere,soil,rocks,aid terrain.
    The rover doesn't seem to be ready to stop just yet. If Opportunity can continue on,it will reach another major investigation site when its odometer hits 26.2 miles. Opportunity has beer working on Mars since January 2004.
    Researchers believe that clay minerals exposed near Marathon Valley could hold clues to Mars's ancient environment. Opportunity's continuing travels will also help researchers as the, plan for an eventual human mission to the Red Planet.

    Opportunity is a record breaking rover in the sense of________.
    A: how long is has stayed in space
    B: how far it has traveled
    C: how much investment it has involved
    D: how many facilities it has been equipped with

    答案：B
    解析：
    根据第一段“NASA's Mars rover Opportunity has boldly gone where no rover has gone before—at least in terms of distance.”可知，“机遇号”比任何漫游车行驶的距离都长。故选B。


    从第二、三段可知，“机遇号”并不是为长途行驶而设计的，它本来预定只能行驶大约一千米。因此“机遇号”在被设计时，约翰并没有准确地知道它的价值。故本题选 B。


    由第四段“The objective of the rovers was to help scientists learn more about the planet and to search for signs of life , such as the possible presence of water.”可知，把“机遇号”和 “勇气号”送上火星的目的之一是寻找生命的迹象。故本题选D。


    根据文章最后两段可知，如果“机遇号”继续行驶的话，在它行驶到26.2英里的时候，它就会到达另一个重要的研究场地——马拉松谷，因此C项正确。倒数第二段第一句说，“机遇号”不会止步于此，故A项错误。B、D项文中并未提到。


    由最后一段可知，“机遇号”接下来的工作能够帮助研究人员实施人类最终登陆火星的计划。故B项“科学家正努力把更多的人类送上火星”是正确答案。

    Directions：　　Please write an essay in 160-200 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.
    解析： 这是一篇问题解决型作文。要严格按照提纲中的三个要点来安排作文的结构。第一段首句引用已给出的句子直入主题，下面可用事实支持主题，可用一些数字使事实更具说服力，也可引用现实生活中的实例引起人们的共鸣；第二段具体分析产生水资源缺乏的原因；第三段针对以上原因提出解决问题的办法。
