  • 第1题：

    There are mainly six types of tea in the traditional Chinese concept, namely, black tea, green tea, white tea, oolong tea, yellow tea and dark tea.

    Black tea is fully fermented, so its leaves and tea soup are red.The flavour and aroma of black tea are rich and robust with a little bitterness.Famous black tea includes Qimen black tea, Tanyang Gongfu, etc.

    Green tea is non-fermented and the tea soup is green.It has a more delicate and fresher flavour than black tea.Famous green tea includes West Lake Longjing Tea, Bi Luo Chun Tea, etc.

    White tea, originated in Fujian Province, is probably the rarest tea.It is slightly fermented, just left to dry as it is.White tea has a lighter colour than other types of tea with a subtle flavor.

    One of the most famous white teas is White Tip Silver Needle.

    Oolong tea is partially fermented and has the most difficult tea processing.The result is a distinctive flavour, which combines the freshness of green tea and the mellowness of black tea.Famous oolong tea includes Tie Guan Yin, Da Hong Pao, etc.

    Yellow tea is relatively unknown.It is fermented.In the tea processing, the leaves are mounded and dried by the heat of fermentation.The flavour is close to green and white teas.Famous yellow tea includes Junshan Yinzhen, Huoshan Huangya, etc.

    Dark tea is post-fermented, which gives the leaves a dark black colour.The tea soup has a strong aroma with a thick and robust flavour.Famous dark tea includes Hunan dark tea, Yunnan Pu-erh tea, etc.

    Ways to Create Colors in a Photograph

    There are two ways to create colors in a photograph.One method called additive,starts with three basic colors and adds them together to produce some other color. The second method,called subtractive,starts with white light(a mixture of all colors in the spectrum)and,by taking away some or all other colors,leaves the one desired.
    In the additive method,separate colored lights combine to produce various other colors.The three additive primary colors are green,red and blue(each providing about one-third of the wavelengths in the total spectrum).Mixed in varying proportions,they can produce all colors.Green and red light mix to produce yellow,red and blue light mix to produce magenta(a purplish pink);green and blue mix to produce cyan(a bluish green).When equal parts of all three of these primary-colored beams of light overlap（重叠）,the mixture appears white to the eye.
    In the subtractive process colors are produced when dye（染料）absorbs some wavelengths and so passes on only part of the spectrum.The subtractive primaries are cyan,magenta and yellow; these primaries or dyes absorb red,green and blue wavelengths respectively,thus subtracting them from white light. These dye colors are the complementary colors to the three additive primaries of red,green and blue.Properly combined,the subtractive primaries can absorb all colors of light, producing black.But,mixed in varying proportions,they too can produce any color in the spectrum.
    Whether a particular color is obtained by adding colored lights together or by subtracting some light from the total spectrum,the result looks the same to the eye.The additive process was employed for early color photography. But the subtractive method,while requiring complex chemical techniques,has turned out to be more practical and is the basis of all modern color films.

    It can be inferred from the passage that white can be produced by______.
    A:mixing different proportions of magenta,green and red
    B:mixing equal proportions of green,red and blue
    C:mixing different proportions of cyan, yellow and blue
    D:mixing equal proportions of black,red and green

    答案：B
    解析：
    这是一道理解主旨的题。第一段第一句明确提出，照片中的颜色是通过加色法和减色法两种方式形成的。之后二、三段分别详细介绍了两种方式的具体情况。A、B、D选项均不是文章主旨。
    第二段最后一句话提到当等比例的三原色重叠时，形成白色。因此B选项是正确的。
    这是一道关于减色法过程的细节题。根据第三段第二句话可知，减色法中的三原色分别是蓝绿色、紫红色、黄色；它们分别从白色中吸取红色、绿色、蓝色的光波。故可得出蓝绿色吸收的是红色的光波。
    根据文章内容可知，加色法的三原色分别为红、绿、蓝，减色法的三原色分别是蓝绿色、紫红色、黄色。没有黑色和白色。
    根据最后一段可知，通过加色法和减色法所获的特定颜色用肉眼来看效果是一样的。加色法用于早期彩色照片的处理，而减色法虽然需要复杂的化学工艺，却被证实是更为实用的方法，所以它成为了现代彩色胶片的基础。由此可知相对于加色法，减色法更为有效。

    A student is instructed to arrange four cards in a row on a table. She has six cards to choose from, each of which has a different color: black, red, blue, green, yellow, and brown. If the student follows these instructions but otherwise chooses her cards randomly, what is the probability that her arrangement will be blue, red, yellow, and green, in that order?
    A

    1/90

    B

    1/ 180

    C

    1/360

    D

    1/540

    E

    1/720


    正确答案： B
    解析：
    从6张不同颜色的卡片中选出其中四张排列为1列，第一张卡片有6中选择，第二张卡片有5中选择，以此类推，第三张和第三张卡片分别有4种和3种选择，所以将4张卡片排在一起的可能性为6 x 5 x 4 x 3 = 360种。所以概率为1/360。

    C

    D

    White dwarf, red giant, black dwarf, yellow dwarf.


    正确答案： C
    解析：
    是非题。文章首段指出太阳目前为yellow dwarf star，第二段描述在变化的第一阶段太阳会成为red giant star，接下来第三段又指出太阳缩小后会变成white dwarf star，而文章最后一句描述太阳能量用尽后会变为black dwarf。因此太阳的演变过程是yellow dwarf, red giant, white dwarf, black dwarf，故选C。

  • 第13题：

    C．enum test{RED=-1，YELLOW，BLUE，BLACK}；

    D．erium test{RED，YELLOW=6，BLUE，BLACK}；


    正确答案：A
    解析：在枚举类型定义中，如果没有进行显式设置，则隐式设置整数值。将枚举声明中的第一个枚举值设置为O。后续所有成员的值如果没有进行显式设置，便确定为前一个成员的值加1。所以只能选择答案A)。选项B)中对应的枚举值是0，4，5，6；选项c)中对应的枚举值是-1，0，1，2；选项D)中对应的枚举值是0，6，7，8。

  • 第14题：

    下列选项中不能正确定义结构体的是_______。

    C．struct color

    D．struct {int red； {int red； int green; int green； int blue； int blue； }cl； }cl；


    正确答案：B
    解析：将一个变量定义为标准类型与定义为结构体类型不同之处在于：后者不仅要求指定变量为结构体类型，而且要求指定为某一特定的结构体类型(例如，struct color)，不能只指定结构体名。其中可以不出现结构体名，答案D就是缺省结构体名的隋况。而变量名歹婊必须放在成员列表后面，所以B答案不能正确将cl定义为结构件变量。
