  • 第1题：

    可以设置超链接被点击过后样式是红色字体的是()。

    A.a:link{color:red}

    B.a:hover{color:red}

    C.a:visited{color:red}

    D.a:active{color:red}


    答案：C

    解析：a:link ：是未被访问的样式，可以在里面加很多东西，比如说去掉下划线，换颜色等功能都能在这里实现；

    a:visited ：是已被点击后的样式，也可以在里面加很多元素，可以去下划线，改颜色，放大等功能；

    a:hover ：这个是鼠标悬停的样式，是把鼠标停在超链接的位置的时候可以设置变颜色；

    a:active ：是能把鼠标点上去的时候，瞬间出的样式，在很多网站上都有这种样式的


  • 第2题：

    以下CSS选择符定义中，______属于类选择符。

    A.P{color:red; font-size:12pt}
    B.p.blue{color:blue}
    C.#Red{color:red;)
    D.PEM {background: yellow}

    答案：B
    解析：
    本题考查CSS的基础知识。CSS(Cascading Style Sheets，层叠样式表，简称为样式表)是用于(增强)控制网页样式并允许将样式信息与网页内容分离的一种标记性语言。在CSS基本语法结构中，样式表的结构为：选择符{属性1：值1；属性2：值2；…}其中，选择符有如下几种形式：(1)HTML标记。任何HTML标记都可以是一个CSS的选择符，如P{color:red;font-size:12pt}。(2)类选择符。一个选择符能有不同的CLASS(类)，因而允许同一元素有不同的样式。格式如下：标记名：类名{属性1：值1；属性2：值2；…}(3)ID选择符。ID选择符个别地定义每个元素的成分。这种选择符应该尽量少用，因为它具有一定的局限。一个ID选择符的指定要有指示符“#”在名字前面。(4)关联选择符。关联选择符是用空格隔开的两个或更多的单一选择符组成的字符串。这些选择符可以指定一般属性，而且因为层叠顺序的规则，它们的优先权比单一的选择符大。

  • 第3题：

    The traffic lights were red when the driver reached them．To the surprise of his passenger,the ear did not slow down．Unexpectedly the passenger was thrown forward in the vehicle as the driver put on his brakes at the last moment．The car stopped just in time.
    "Sorry,I didn't notice the light．I thought it was green until I saw that it was the top light which was shining."
    This strange story is quite true．About ten men in every hundred are color blind in some way;women are luckier--only about one in two hundred suffers from color blindness.
    In some cases,a man may not be able to see deep red．He may think that red,orange and yellow are all the same as green.
    People often like one color more than others．Blue is the color of the sky and sea．Green makes us think of fields and trees．Red is the color of blood and makes some people think of danger．Black is the color of night．In the dark we cannot see what is around us so we are sometimes afraid of the unknown and do not like black as a color.

    One is considered as a color blind man if__.

    A.he can see the difference between red and deep red
    B.he can see the difference between blue and green
    C.he can't tell the difference between orange and green
    D.he thinks green is the same as blue

    答案：C
    解析：
    参见第四段。

  • 第5题：

    共用题干
    The fact that blind people can see things using other parts of their bodies apart from their eyes may help us to understand our feelings about color._________(46)
    _________(47)These discoveries have grown into a whole discipline of color psychology that now finds application in everything from fashion to interior decoration. Some of our preferences are clearly psychological.________(48)For primitive man,activity during the day meant hunting and attacking,which he soon saw as red,the color of blood and rage and the heat that came with passive defense and self-preservation.
    _________(49)People exposed to bright red show an increase in respiration rate,heartbeat, and blood pressure;red is exciting._________(50)Because of its exciting connotations,red was chosen as the signal for danger,but closer analysis shows that a vivid yellow can produce a more basic state of alertness and alarm,so fire engines and ambulances in some advanced communities are now rushing around in bright yellow colors that stop the traffic dead.

    __________（49）
    A:Dark blue is the color of the night sky and therefore associated with passivity and calm, while yellow is a day color with associations of energy and incentive.
    B:Similar exposure to pure blue has exactly the opposite;it is a calming color.
    C:Color psychology is concerned with the effects of color on mood,emotion,behavior.
    D:Manufacturers have discovered by trial and error that sugar sells badly in green wrappings, that blue foods are considered unpalatable,and that cosmetics should never be packaged in brown.
    E:If they can sense color differences then perhaps we,too,are affected by color unconsciously.
    F:Experiments have shown that colors partly because of their physiological associations,also have a direct psychological effect.

    答案：F
    解析：
    本题考查的是对上下文之间意义关系的理解。根据第一句The fact that blind people can see things using other parts of their bodies apart from their eyes may help us to understand our feelings about color（盲人可以使用除了眼睛以外的其他身体部位看见东西这个事实，也许可以帮助我们了解自己对颜色的感受），可以判断出来只有E选项的内容和这句能街接上。
    本题考查的是对上下文之间意义关系的理解。根据第二句中的These discoveries可以判断出本段第一句中提及的应该是关于颜色的诸多具体的发现。
    本题考查的是对上下文之间意义关系的理解。前一句提到：我们对颜色的偏好是心理因素导致的，接下来对此举例说明，因此A选项的内容吻合。
    本题考查的是对上下文之间意义关系的理解。后一句举例说明颜色对我们产生的生理方面的影响导致颜色给我们带来的心理作用也不同，因此前一句是对此的概括性说明。F选项的内容符合。
    本题考查的是对上下文之间意义关系的理解。和前一句中“红色让人兴奋”形成对比，该句中是说蓝色和红色给我们带来的心理作用刚好相反，蓝色让人镇静，exciting和calming以及opposite都是关键词，因此选B。

    cules can be used outside the lab.

    _________(51)
    A:throw
    B:prevent
    C:create
    D:keep

    答案：B
    解析：
    从空格前的“also may help”和上文的“prevent”一词可知答案。
    bridge supports意为“桥梁支柱”，后用or连接，是指与桥梁支柱同样的事物，所以插入语部分应该指“其他建筑材料”。another指“再，另”;the other指其他所有的；others是代词，后 面不能跟名词。other泛指其他的，后可跟名词。
    按照逻辑推理，应该是倒塌前变红色，这样才起作用，所以选before。
    secret behind…表示“……背后的秘密”;under也有底下的意思，但更强调地理空间；用 于抽象事物时，多用behind。
    介词in可以表示形式、形状或数量。
    这里指，分子构成了各种我们肉眼所看到的事物。根据上下文可知，应选择everything。
    depends on后面是一个宾语从句，在这个从句中，atoms是contains的宾语，what kinds of 可用来修饰atoms。
    根据上下文可知应选color。
    应选择和injured相近的词语，所以选weak。
    这里指分子受损或变弱时键会断开，所以选break。
    这里指实验结果令人振奋，所以应选results。
    前文说断开的键复合，相对应的，红色应是消失、褪去。
    从空后的“in sunlight”可知应选outside。
    上文提到，光会使红色褪去，所以阳光会使这一警报失效。
    这里指还需要做很多工作，所以选a lot of 。
