B.enum test{RED,YELLOW=4,BLUE,BLACK};

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7题:

[A]reduce [B]narrow [C]dwarf [D]shrink


正确答案:A

本题考查动词词义的辨析。填入的动词,表达Increased use of IC cards(对IC卡使用的增加)对 the space needed for ticket vending (售票需要的空间)的影响。根据上文可知道,IC卡的使用替代了传统的车票和定期券,因此空格所在句子的含义是:IC卡使用的增加减少了售票所占的空间。关键看四个选项哪个与space搭配,符合文意。[A]项reduce“减少,缩小”,用法较为广泛,除表示数量、大小、价格等的减少外,还可以接表抽象含义的词,如reduce the risk of detection(减少被发现的危险),原文意为:对IC卡使用的增加将会减少售票占用的空间。[B]项narrow“使变狭窄,使缩小”与space搭配,指“使空间变得狭小”,有“拥挤”的含义;[C]项dwarf指“(通过与大的事物比较)使显得小”,而实际大小没有改变,如Most professional basketball players dwarf other men(大多数职业篮球运动员使别人显得矮小);[D]项shrink意为“使事物本身缩小或萎缩”,如shrink the markets for the exports(使出口市场萎缩),均不符合文意。

第8题:

已知枚举类型声明语句为: enumCOLOR{WHITE,YELLOW,GREEN=5,RED,BLACK=10}; 则下列说法中错误的是

A.枚举常量YELLOW的值为1

B.枚举常量RED的值为6

C.枚举常量BLACK的值为10

D.枚举常量WHITE的值为1


正确答案:D
解析:枚举变量中的枚举元素系统是按照常量来处理的。如果没有进行元素赋值操作,那么元素将会被系统从0开始自动递增地进行赋值操作,但是,如果一旦定义了某一个元素的值,那么系统将对下一个元素进行按前一个元素的值加1操作,故wHITE=1,YELLOW=2,GREEN=5,RED=6,BLACK=10。
