    二、七选五型阅读
    考生需要在语篇信息存在缺失的情况下，准确理解整篇文章，特别是设题部位前后句的逻辑关系，通过上下文的线索进行判断，预测下文，然后做出正确判断。
    命题分析：我们如果把整篇文章看成一个信息群，这个信息群实际上是由两大信息版块构成的：
    已知信息：原文在五处空缺之外的没有被挖掉的信息
    待选信息：七个待选选项中的信息
    这两个信息板块间绝不是孤立的，而是有紧密的互动逻辑关系，连起来是一篇完整的文章。
    考试题型对学生的考察能力来看无外乎两个方面：
    （1） 把握整篇文章的布局和逻辑层次关系
    （2） 把握微观信息间关联性（即空格前后句间关系）
    解题方法：词汇同现、词汇复现、代词妙用、数字线索、逻辑线索。
    Muzak
    The next time you go into a bank， a store， or a supermarket， stop and listen. What do you hear？ _____ （71） It's similar to the music you listen to， but it's not exactly the same. That's because this music was especially designed to relax you， or to give you extra energy. Sometimes you don't even realize the music is playing， but you react to the music anyway.
    Quiet background music used to be called “elevator （电梯） music” because we often heard it in elevators. But lately we hear it in more and more places， and it has a new name “Muzak”. About one-third of the people in America listen to “Muzak” everyday. The music plays for 15 minutes at a time， with short pauses in between. It is always more lively between ten and eleven in the morning， and between three and four in the afternoon， when people are more tired.______ （72）
    If you listen to Muzak carefully， you will probably recognize the names of many of the songs. Some musicians or songwriters don't want their songs to be used as Muzak， but others are happy when their songs are chosen. Why？ _____ （73）
    Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel. It has been proven that Muzak does what it is designed to do. Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background. _____ （74）Supermarket shoppers buy 38 percent more groceries.
    _____ （75）They say it's boring to hear the same songs all the time. But other people enjoy hearing Muzak in public places. They say it helps them relax and feel calm. One way or another， Muzak affects everyone. Some farmers even say their cows give more milk when they hear Muzak！（  2010年高考英语北京卷）
    A. Some people don't like Muzak.
    B. The music gives them extra energy.
    C. Music is playing in the background.
    D. Factory workers produce 13 percent more.
    E. Muzak tends to help people understand music better.
    F. They ge t as much as $4 million a year if their songs are used.
    G. Muzak is played in most of the big supermarkets in the world.
    答案：CBFDA
    代词妙用：代词指代前面提到的thing， 所以只要找到与代词含义一致的词就可搞定。
    71空格后面出现“It's similar to the music you listen to，”那么我们只要分析出其中的“it”的具体指代即可，通过题目及略读下文，我们很容易知道该文介绍一种音乐，而且第一段故作悬念，一直未给出其名字，所以我们只要找到选项中包含音乐一词而没有点名缪扎克一词的即可，很容易锁定BC选项，因为B项意义与下文相去甚远，故舍B取C没商量。
    75空格后出现“They say it's boring to hear the same songs all the time.”，同理，我们就要确定“they”的具体指代，首先由于“say”的出现，我们锁定“they”为人的复数，所以轻松锁定ADF，所谓真金不怕火来炼，D显然逻辑不通，F由于其主语也为人，段落第一句永远不会出现意思不明的代词（we， you 除外，因为它们可以明确指代广义的人），故轻松排除F选出真金A。
    72此题虽然不是明显的后文出现代词，但其前亦有代词出现，“It is always more lively between ten and eleven in the morning，”下文承接上文，肯定有联系，找出“it”的具体指代-the music， 轻松选出B项。（注：也可应用词汇复现法）
    词汇复现法：情非得已时选择的一种方法，知道与前后文中有词汇重复的选项即可，有时也可指含义一致的词汇，如72
    73前文中“but others are happy when their songs are chosen”有“their songs”， F项亦有相同词汇出现，放进去，意思通晓明白，搞定。
    74后文中“Supermarket shoppers buy 38 percent more groceries.有”percent more“，D项亦有相同词汇出现，且意思连贯，选出即可。
    72题中前句中出现”when people are more tired. “能够与”tired“相对应的四选项中只有”energy“，累了对应能量，亦可做出此题。
