    分析 众所周知，知识是财富的宝库，但是实践是它的钥匙．

    解答 答案：A
    根据句意可知，第一个空表示泛指"一所知识的宝库"，故用不定冠词a；第二空表示特指打开这所宝库的钥匙，这里应填定冠词the；故选A．

    点评 本题考查了冠词的用法．做本题时，首先根据句意判断出空白处的意义特征（表示特指还是泛指），然后结合定冠词及不定冠词的用法，选出正确答案；因此，做此类题时，需要熟练掌握定冠词，不定冠词以及零冠词的具体用法．

    Have you ever considered volunteering? It gives you a chance to give back. You’ll feel a sense of pride that you are volunteering your time, and a local organization will benefit, too. But how to volunteer? Follow the three steps before you enjoy it.

    Pick an organization. 1. You’re likely to be happier and volunteer longer at an organization that supports a cause you care about. For example, if you’re interested in animal welfare, maybe you want to volunteer at an animal shelter. Much like job search sites, you can also use volunteer websites like Volunteer Match or Serve.gov to help you find volunteer opportunities in your area. If you still can’t narrow down where you want to volunteer, start asking people you know where they volunteer. 2.

    Be clear what you can offer. First identify your skills. For example, maybe you could write brochures for local nonprofits if writing is your style. 3. You need to be sure how much time you can give to an organization based on your other commitments. If you try to do too much, you ‘re more likely to give up.

    4. Treat the application like a job. Spend some time preparing for the interview, much as you would for a job interview. 5. Ask what’s expected of volunteers. For instance, volunteers at a museum may be expected to learn parts of the galleries to give tours. Start volunteering slowly. That is, it’s better to commit to just a little bit of time at first to see if you like volunteering at the organization.

    A.Apply and get started.

    B.Volunteer in person or online.

    C.Then don’t forget to review your weekly schedule.

    D.You’d better focus on the causes you like very much.

    E.You may find one of them has the perfect opportunity for you.

    F.It is also a time for you to assess whether the organization is fit for you.

    G.First find an organization that’s a good fit for you, and then decide what you have to offer.

    13．Friends play an important part in our lives，and although we may take  friendship  for granted，we often don't clearly understand how we make friends．While we get on well with a number of people，we are usually friends with only a very few．For example，the average among students is about 6per person．In all the cases of friendly relationships，two people like one another and enjoy being together，but beyond that，the degree of closeness between them and the reasons for their shared interests vary greatly．As we get to know people we take into account things like age，race，economic condition，social position，and intelligence．Although these factors are not of prime importance，it is more difficult to get on with people when there is a marked difference in age and background．
    Some friendly relationships can be kept on argument and discussion，but it is usual for close friends to have similar ideas and beliefs，to have attitudes and interests in common-they often talk about"being on the same wavelength"．It generally takes time to reach this point．And the more closely involved people become，the more they rely on one another．People want to do friends favors and hate to break a promise．Equally，friends have to learn to put up with annoying habits and to tolerate differences of opinion．
    In contrast with the marriage，there are no friendship ceremonies to strengthen the association between two people．But the supporting and understanding of each other that results from shared experiences and emotions does seem to create a powerful bond，which can overcome differences in background，and break down barriers of age，class or race？

    32．How does the author understand"friends"in this passage？D
    A．Every student has 6friends．
    B．Everyone understands clearly how to make friends．
    C．All the people who get on well with each other are friends．
    D．Friends are closer than those just getting on well with each other．
    33．What should we avoid when making friends？D
    A．Good economic condition．
    B．Argument and discussion．
    C．The same race，hobby and nationality．
    D．A marked difference in age and background．
    34．What do the underlined words"being on the wavelength"mean in Paragraph 2？C
    A．Having the same background．
    B．Using the same frequency while talking．
    C．Having similar ideas，beliefs，attitudes and interests．
    D．Keeping the same friendly relationship as other people do．
    35．How do people strengthen friendly relationship according to the passage？D
    A．To hold friendship ceremonies．
    B．To completely get rid of differences in background．
    C．To make friends with those who are of the same age and of the same race．
    D．To support and understand each other by sharing experiences and emotions．

    3．Until recently，scientists had mapped only about 20 percent of the sea floor．But our knowledge of the deep seas is changing because of information from satellites．Scientists have produced a new map that provides a detailed picture of the oceans．The map is expected to help oceanographers （海洋学家），industry and governments．
    The new map is twice as detailed as the map made 20 years ago．David Sandwell is a geophysics professor at the University of California．He and other scientists worked on the mapping project．He says they turned to space to look deeper into the ocean．
    The scientists collected and studied information from two satellites．Some of the data came from the European Space Agency's Cryo-2 satellite．It was placed in Earth's orbit to watch sea ice．The other satellite is the American space agency's Jason-1．It is studying the surface of the oceans．Scientists combined the satellite data with images gathered by sonar （声波定位仪） equipment on ships．Sonar works by sending sound waves through the water．When the sound waves hit an object，its presence is confirmed．
    The new map shows the sea floor as it has never been seen before．It shows thousands of underwater mountains and places where continents pulled apart．It shows where earthquakes were active many years ago．They all are buried deep underneath the ocean floor．
    David Sandwell says the map is a powerful tool for fisheries，those interested in protecting the environment and for oil exploration．
    "The petrol exploration industry is interested in how to reconnect the continents，bring them back together tectonically so you can map the basins on one continental edge-say，Africa-and use that to establish where the similar basin would be on the other continental edge in South America．"
    If scientists know that information，they may be able to find oil fields．The new data also will help scientists improve their estimates of ocean depths．This information can help ships travel safely and improve military operations and scientific projects worldwide．
    Mr．Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides．

    32．Which one is not mentioned about the benefits brought by the new map？C
    A．Fisheries．
    B．Scientific projects．
    C．Ship manufacture．
    D．Oil exploration．
    33．What can we know about the new map？B
    A．It shows where earthquakes will happen．
    B．It will be helpful to industry and governments．
    C．It is three times as detailed as the old one years ago．
    D．It shows the sea floor as it has ever been seen before．
    34．The text is likely to appear inC．
    A．a newspaper    
    B．an advertisement
    C．a science magazine    
    D．a finance report
    35．Which of the following can be the best title for the text？D
    A．The detailed picture of the oceans
    B．Underwater mountains and places
    C．More discoveries about the oceans
    D．Scientists create new maps of ocean floor．

    14．I had made up my mind a long time ago that I would not give homeless people money，because I could never be sure what that money would be used for．Instead，I decided，I would buy them a sandwich，a cold drink on a hot day，a cup of coffee，whatever I could manage．
    I was out recently and saw a homeless man outside of a Starbucks．So I dropped another few coins in and went into the Starbucks．I decided I would buy this man lunch．I bought a sandwich and soda．
    Just as I was leaving the store，two policemen were approaching the man．Obviously the shop owners had complained of his wandering and the police were there to draw him away from the storefronts．Just as they were about to wake him，I asked one of the officers if it was all right if I just gave the man something before he went I was not sure why I asked the permission but the policeman said sure and I just left the bag in the man's cart，got in my car and drove off．
    As I was driving off，I remember thinking，"I hope people saw that"．Then I had to seriously ask myself why I hoped people had seen me give the man a sandwich from Starbucks．Was it because I wanted people to think，"She's such a nice person!"？Why did I hope others had seen me do it？I continued to wonder this all evening．
    The next morning it came to me．I wanted people to have witnessed that small act of kindness not so that I would receive credit and praise but so that they might be inspired to do the same and in so doing that others still would witness their acts of kindness．Thus the whole spirit of pity and giving would be lasting．

    41．Why did the author decide to buy food or drinks for homeless people instead of giving money？A
    A．Because they might use the money to buy drugs．
    B．Because the author might not have enough changes to give out．
    C．Because the policeman might not allow the author to do so．
    D．Because the author couldn't manage it．
    42．When the police approached the homeless man，he wasD．
    A．begging outside   B．buying goods   C．awake   D．asleep
    43．Why did the author hope people saw her give some food to the homeless man？C
    A．She wanted to be praised by others．
    B．She was not sure whether other people would let her do that
    C．She wanted to inspire others to do the same thing．
    D．She just wanted others to witness her act of kindness．
    44．The author can be best described asC．
    A．bad-tempered    B．hard-working    C．kind-hearted   D．self-confident
    45．What's the purpose of the passage？B
    A．To show the author is great．
    B．To encourage people to help others．
    C．To introduce an experience that changed the author．
    D．To call on people not to give money to a homeless man．
