英文翻译练习(一) The status of Philosophy in Chinese culture has always been regarded as a comparison with that of religion in other cultures. In China, Philosophy is the concerned field by each educated one. Long time ago in China, a person would firstly accept enlightened education in Philosophy if he could be given education. Children should read the Analects, Mencius, The great Learning, The Doctrine of mean once they entered school. The Four Books were regarded as the most important documents after Song(regarded as “new Confucianism”in west).When children began to learn words, the commonly used textbook is Three Words, in which every three words a group, every six words one sentence, and the even sentence rhyme has rhyme, easy to read aloud and easy to remember. In fact, this book is used to learn words for Chinese children. The first sentence of Three Words “Man’s nature is good at birth.” Is the basic idea of philosophy of Mencius.

华师网络学院作业答案-数据结构判断题

消除递归不一定需要使用栈。 答案:正确 在开散列表中不会出现堆积现象。 答案:正确 在链栈上进行进栈操作时,不需判断栈满。 答案:正确 算法的正确性,一般不进行形式化的证明,而是用测试来验证。 答案:正确 顺序表不需存放指针,链表要存放指针,故链表的存储空间要求总是比顺序表大。 答案:错误 如果n个顶点的无向图有n条边,则图中肯定有回路。 答案:正确 图G的生成树T是G的子图。 答案:正确 数组的基本运算有读、写、插入、删除等。 答案:错误 不管树的深度和形态如何,也不可能构造出一棵有100个结点的哈夫曼树。 答案:正确 如果根结点的左子树和右子树高度差不超过1,则该二叉树是平衡二叉树。 答案:错误 排序的目的是为了方便以后的查找。 答案:正确 以中序方式遍历一个堆,则得到一个有序序列。 答案:正确 二叉树中可能所有结点的度都小于2。 答案:正确 顺序表可以按序号随机存取。 答案:正确 在二叉排序树中,即使删除一个结点后马上再插入该结点,该二叉排序树的形态也可能不同。答案:正确 队列在使用中必须设置两个指针,分别指向真正的队头和队尾的位置。 答案:错误 数据的逻辑结构和运算集组成问题的数学模型,与计算机无关。

对称矩阵压缩存储后仍然可以随机存取。 答案:正确 有向图中顶点i的出度等于邻接矩阵中第i行中1的个数;入度等于第i列中1的个数。 答案:错误 树和森林都可转化为二叉树,故对给定的二叉树,不能区分是由树还是森林转换来的。 答案:错误 循环队列中入队和出队的节点位置可出现在数组的任一端,已不满足“一端进另一端出”的要求,故实际上已不是队列了。 答案:错误 顺序查找法不仅可用于顺序表上的查找,也可用于链表上的查找。 答案:正确 有向图中边数等于邻接矩阵中1的个数;也等于邻接表中的边表结点数。 答案:正确 直接插入排序是稳定的,而Shell排序就是调用若干趟直接插入排序,故也是稳定的。 答案:错误 基数排序不需进行关键字间的比较,故执行时间比基于比较的排序方法要快。 答案:错误 由二叉树的先根和后根序列可以唯一确定该二叉树。 答案:错误 不论数据如何组织,分别在10000个结点和10个结点的查找表中进行查找,前者的平均查找长度肯定比后者大。 答案:错误 在线索二叉树上,求结点的(遍历)前趋和后继时可利用线索得到,即不必进行遍历了。 答案:错误 单链表中取第i个元素的时间与i成正比。 答案:正确 广义表不仅是线性表的推广,也是树的推广。 答案:正确 拓扑排序可以分析某工程能否顺利进行。 答案:正确 哈夫曼树中不存在度为1的结点。 答案:正确 在数据结构中,算法的空间耗费包括代码和数据两部分。

Americans are much more likely than citizens of other nations to believe that they live in a meritocracy, i.e. Government by people selected according to merit. But this self-image is a fantasy: America actually stands out as an advanced country in which it matters most who your parents were, the country in which those born on one of society’s lower rungs have the least chance of climbing to the top or even to the middle. And if you ask why America is more class-bound in practice than the rest of the Western world, a large part of the reason is that our government falls down on the job of creating equal opportunity. The failure starts early: in America, the holes in the social safety net mean that both low-income mothers and their children are all too likely to suffer from poor nutrition and receive inadequate health care. It continues once children reach school age, where they encounter a system in which the affluent send their kids to good, well-financed public schools or, if they choose, to private schools, while less-advantaged children get a far worse education. 美国人可能比任何其他国家的人都更相信他们生活在一个精英制度之下,人们推选的政府也是据其优势。然而,这个自我形象是一种幻想:作为先进国家,实际上美国的突出特点是出身至关重要,在这个国度里,来自社会底层的人几乎没有机会爬到社会中层,更不用说社会顶层。 如果你要问为什么实际上美国比其他西方国家都要阶级分明,主要原因就是我们的政府在创造公平机会方面的失败。 这种不公平很早以前就开始了:在美国,由于社会安全网存在漏洞,这就意味着低收入的母亲和他们的孩子完全有可能存在营养不良,得不到足够的医疗服务。孩子到了上学年龄这种情况也不会得到改观,他们所遇到的体制是富人可以送自己的孩子到资金充足的好的公立学校上学,如果愿意,还可以从送到私立学校上学,而穷人孩子接受的教育却非常差。

华师网络学院作业答案计算机组成原理计算题

若某计算机的主频为800MHz,每个CPU周期平均包含4个主频周期,每个指令周期平均有3个CPU周期,问: (1)该机平均指令的执行速度为多少MIPS(百万条指令每秒)? (2)若主频提高到1000MHz,每个CPU周期平均包含2个主频周期,采用流水线方式,每个指令周期平均为个CPU周期,则平均指令的执行速度又是多少MIPS? 答案: 解:(1)因为机器主频为f=800MHz,所以主频周期T=1/(800×106) =(μs), 每个CPU周期平均包含4个主频周期,所以CPU周期T CPU=4 T=4×(μs)=(μs) 指令周期T 指令 =3 T CPU=3×=(μs) 则指令的执行速度V1=1/ T指令=1/ (μs) =(MIPS) (或800÷(4×3)= (MIPS) ) (2)1000÷(2×)= (MIPS) 设机器字长为8位(运算时为9位),已知二进制数X=-101101,Y=100110, 试用双符号位补码求X+Y和X-Y的值,要求写出计算机中的运算步骤,并指 出是否有溢出。 答案: [X] 补=1 [Y] 补 =000100110 [-Y] 补 =0

[X] 补 1 + [Y] 补 000100110 1 (无溢出) [X] 补 =1 + [-Y] 补 =0 1 所以 [X+Y] 补 =1 X+Y=-000111 [X-Y] 补 =1 X-Y=-1010011 一个32位的微处理器,它有16位外部数据总线,总线的时钟频率是40MHz,假定一个总线事务的最短周期是4个时钟周期,问这个处理器的最大数据传输率是多少?如果将数据总线的宽度扩展为32位,那么处理器的最大数据传输率提高到多少?这种措施与加倍外部总线时钟频率的措施相比,哪种更好? 一种单地址指令格式如下所示,其中I为间接特征,X为寻址模式,D为形式地址。I,X,D组成该指令的操作数有效地址E。设R1为变址寄存器,R2为基址寄存器,PC为程序计数器,请写出下表中各种寻址方式名称。 OP I X D 寻址方式 名称 I X有效地址E 立即寻址 0 00 E=D 相对寻址 0 01 E=(PC)+D 变址寻址 0 10 E=(R)+D 寄存寻址 0 11 E=(R)+D,D=0直接寻址 1 00 E=(D) 相对间接寻址 1 01 E=((PC)+D)变址间接式 1 10 E=((R)+D) 寄存器间接寻址 1 11 E=((R)+D),D=0 (1)立即寻址 (2)相对寻址 (3)变址寻址 (4)寄存寻址 (5)直接寻址 (6)寄存器间接寻址
