    The Magic of Sound
    Music is one of the most beautiful forms of artistic expressions ever invented.In movies and plays, music has an added function:it not only moves people but also can shock people.
    Our eardrums can withstand sound within 20 to 80 decibels（分贝）.Once sound exceeds this limit , even beautiful music will become ear-splitting noise and harm health.A strong blast（响声）of high sound can twist and break a solid iron sheet.High sound of 150 decibels can kill a healthy rat.
    In movies,sometimes the hero can produce a sound that ordinary people can't hear and only those who
    have the same ability can feel.In nature,there is actually sound that is beyond our hearing.In physics,the sound that exceeds 20,000Hz is called ultrasonic（超音波的）.Dolphins, whales and bats can make such high-frequency sound.It does no harm to health.
    Sound less than 20Hz is called infrasonic（次声）waves.When we move, the air will vibrate.The vibration of air can produce infrasonic waves.As the frequency of infrasonic waves is close to that of people's internal organs, infrasonic wave may cause resonance（共振）in human bodies.As a result,people's vision may weaken and internal organs may rupture（断裂）.However,whether an infrasonic wave can be used as a weapon depends on its intensity.If its intensity is very low,it won't damage internal organs or a person's health.If the intensity of infrasonic wave exceeds 160 decibels,it is extremely harmful.When wind blows at a force of 3 or 4 over the sea,it will produce infrasonic waves of several decibels.Only typhoons can produce infrasonic waves of over 100 decibels.At present,scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.

    An ultrasonic sound______.
    A:is very loud
    B:does harm to people's health
    C:cannot be heard by people
    D:is produced by the hero in movies

    答案：C
    解析：
    本篇文章主要讲了声音的奇妙之处以及超声波和次声波的一些特征。
    根据文章的标题“The Magic of Sound"以及全文可知，文章最恰当的标题为C项。其余选项表述都不全面。
    根据第二段第一、二句可知，我们的耳膜可以承受的声音在20分贝到80分贝之间，只要超过了这个界限，再美妙的音乐也会成为噪音，损害健康。由此可知，音乐也可能会对人的健康造成危害。
    根据第二段第一、二句可知，我们的耳膜可以承受的声音在20分贝到80分贝之间，超过了这个界限，再美妙的音乐也会成为噪音，损害健康。由此可见，超过80分贝的声音对人是有害的。
    第三段第二句表明，自然界中存在人类听不到的声音。根据第三段第三句可知，这种超过两万赫兹的声音在物理学中被称为超声波。由此可知，超声波是人类听不到的声音。
    根据第四段第四句可知，当次声波的频率与人体内部器官的频率相当时，就会对人体造成危害，又由常理可知振动会产生声音，可推断出人体内存在次声波，因此选择B项。只有当次声波频率与人体内部器官的频率相近时，次声波才会对人有害，所以A项错误；只有超过 160分贝的次声波才能被用作致命武器，并且由最后一段最后一句“At present, scientists can only produce infrasonic weapons in the lab…”可知，次声波用作致命武器还只是实验室的实验结果，现实中并没有出现，所以C项错误；最后一段没有表明次声波可以改善视力，所以D项错误。

    According to some scientists, the computer will do much harm to people’s health as smoking and drugs do.
    A

    does much harm...smoking

    B

    will do as much harm...cigarettes

    C

    will do so much harm...smoking

    D

    does as much harm...cigarettes


    正确答案： A
    解析：
    同级比较，即as…as…句型。该句中will表示推测，原句中as后面连接了的两个词为并列成分，划线部分也应该用名词，即将smoking改为cigarettes。因此答案为选项B。

    A

    make a few decisions for themselves

    B

    deal with some errors with human intervention

    C

    improve factory environments

    D

    cultivate human creativity


    正确答案： B
    解析：
    细节题。末段第二句提到，人类制造的机器人在被控制的工厂环境下能识别仪器板上的极小误差。从中可看出，人类制造的机器人除了可以减少人类的劳动外，还可以在人的监控下处理具体错误。所以B项正确，C项错误。从第三段第一句话可看出让机器人自己做一些决定还是具有挑战性的，也就是说机器人还不能自己做决定，所以A项错误。D项颠倒了人类创造力与机器人之间的因果关系，故也可排除。

    Firstly, the understanding of certain backgrounds is of great significance to the cross-cultural communication. There are two kinds of communication between human beings: one is extroverted, the other is introverted. Like the computer programs, the extroverted communication processes according to the well-edited programs, or it can’t work. On the contrary, communication with the introverts is like that between the twin brothers or sisters, because they have tacit understanding and only need simple sentences or phrases in their conversations.

    正确答案：
    首先,了解背景情况对不同文化之间的交流非常重要。人与人之间的交流有两种情况:一种是外向的,一种是含蓄的。外向的就像是计算机的程序,一切都按照编好的程序进行,否则就运转不了。与此相反的是同含蓄的人交流,这种交流就像是在一起长大的孪生兄弟姐妹之间的交往。因为他们心领神会,谈话时只需简单的句子和词语。

    They consider the use of illusion to be inappropriate in contemporary art.

    B

    They do not agree the marks on a flat surface can ever satisfactorily convey the illusion of three-dimensional space.

    They do not discuss important works of art created in the past.

    D

    They do not think that the representation of nature was ever the primary goal of past painters.


    正确答案： B
    解析：
    题目提到“certain theories of nonrepresentational art”，可将范围定位于文章前三句。文中第一句表明作者观点，即认为艺术和幻觉的研究是不可分割的。第三句后半部分“although”，可知这里是强调的重点。作者表明尽管他对非具象艺术持批评态度，但是并不是针对他们进行批评。由此推知，现代的非具象理论认为错觉在现代艺术中已经不再有用。答案为A。
