1.阅读下列C程序和程序说明，将应填入(n)处的字句写在对应栏内。【说明】下面是一个用C编写的快速排序算法。为了避免最坏情况，取基准记录pivot时，采用从left、right和mid=[(left+right)/2]中取中间值，并交换到right位置的办法。数组a存放待排序的一组记录，数据类型为T，left和right是待排序子区间的最左端点和最右端点。void quicksort (int a[], int left, int right) {int temp;if (left＜right) {hat pivot = median3 (a, left, right); //三者取中子程序int i = left, j = right-1;for(;;){while (i ＜j && a[i] ＜ pivot) i++;while (i ＜j && pivot ＜ a[j]) j--;if(i＜j){temp = a[i]; a[j] = a[i]; a[i] = temp;i++; j--;}else break;}if (a[i] ＞ pivot){temp = a[i]; a[i] = a[right]; a[right] = temp;}quicksort( (1) ); //递归排序左子区间quieksort(a,i+1 ,right); //递归排序右子区间}}void median3 (int a[], int left, int right){ int mid=(2);int k = left;if(a[mid] ＜ a[k])k = mid;if(a[high] ＜ a[k]) k = high; //选最小记录int temp = a[k]; a[k] = a[left]; a[left] = temp; //最小者交换到 leftif(a[mid] ＜ a[right]){temp=a[mid]; a[mid]=a[right]; a[right]=temp;}}消去第二个递归调用 quicksort (a,i+1,right)。 采用循环的办法:void quicksort (int a[], int left, int right) {int temp; int i,j;(3) {int pivot = median3(a, left, right); //三者取中子程序i = left; j = righi-1;for (;; ){while (i＜j && a[i] ＜ pivot)i++;while (i＜j && pivot ＜a[j]) j--;if(i ＜j) {temp = a[i]; a[j]; = a[i]; a[i]=temp;i++; j--;}else break;}if(a[i]＞pivot){(4);a[i]=pivot;}quicksoft ((5)); //递归排序左子区间left = i+1;}}

  • 第2题：

    共用题干
    The majority of people,about nine out of ten,are right-handed.Not until recently,people who were left-handed were considered__________(51),and once children showed this tendency they were forced to use their right hands. Today left-handedness is generally_________(52),but it is still a disadvantage in a world________(53)most people are right-handed.For example,most tools and implements are still designed for right-handed people.
    In sports,__________(54)contrast,doing things with the left hand or foot,is often an advantage.Throwing,kicking,punching or batting from the"wrong"side may result_________(55)throwing off many opponents who are more accustomed to dealing with the_________(56)of players who are right-handed.This is why,in many ________(57)at a professional level,a higher proportion of players are left-handed than in the population as a whole.

    _________(53)
    A:when
    B:that
    C:where
    D:which

    答案：C
    解析：
    根据后面这句：孩子们一旦显示出左撇子的倾向就会被强迫使用右手，可以推断出人们在最近之前一直都认为使用左手是很不好的，因此这里选D "abnormal"，意思是：不正常的。unique“独特的”;eccentric“古怪的”;normal“正常的”。
    generally accepted“普遍接受的”。admit“承认”;approve“同意，许可”;acknowledge“认可”。
    where引导定语从句修饰world。
    by contrast“相比之下”。
    result in“导致，造成”;result from“由于······而造成”。
    majority“大多数”;minority“少数”;plenty“很多”，通常修饰不可数名词； lack“缺乏”。这句话的意思是：从反面投掷、踢腿、拳击或者是用球拍击打可能会把大多数习惯了对付使用右手的对手们彻底击败。
    game“比赛，赛事”;hobby“业余爱好”;activity“活动”;round“轮（比赛）”。这句话的意思是：这就是为什么在很多专业级别的比赛中，左撇子的比例要高于普通人群中左撇子的比例。
    be connected with“跟······联系在一起”;related要和介词to搭配使用；mix “混合”，意思在这里不合适；combine“结合”，常和with搭配，意思不合适。本句话的意思是： “右”这个词在很多语言中都意味着“正确”或者和“合法”联系在一起。
    be associated with sth.“和······相关联”，这句话中associated with "left", 是定语，修饰words。
    根据句中转折连词whereas可以判断两种情况形成对照，既然和“右”相关的词汇意味着“正确”“合法”，因此whereas后的句子中说的就是相反的情况，因此这里选择 negative , negative association的意思是“负面的含义”。
    There is a close association between...and…意思是：······和······之间关系密切。这句话的意思是：而且在很多原始的部落里，左手和死亡也密切相关。
    tie“绑，捆”; attach“连接，附属”; bring“带来”; remove“拿走，脱掉”。这句话的意思是：有时候孩子的左手被绑在背后避免他使用。
    这里是there be结构。
    这句话的意思是：将来如果孩子们可以自己选择，一定会有更多的左撤子，而由于被迫使用右手导致轻微心理问题的人数也会减少。
