2002年国家公务员考试行测真题及答案A类试卷：言语理解与表达部分
石家庄：/邯郸站：/保定站：/沧州站：/唐山站：/秦皇岛：/言语理解与表达(共30题，参考时限30分钟)本部分均为单项选择题，着重考查考生对语言文字的理解和驾驭能力。
这种能力包括：对句子一般意思和特定意义的理解；对比较复杂的概念和观点的准确理解；对语句隐含信息的合理推断；根据上下文，恰当选用词语；准确地辨明句义，筛选信息。
注意：问题可能是选择一个词语或一个句子，使表达最为准确，也可能是考查对文字内容的理解，你的选择应与题目要求最相符合。
[例题]阅读以下文字，回答下面的问题。
板块的边界并不就是海陆的边界，大部分板块既有陆地又有海洋。
作为板块边界的活动构造有裂谷带、俯冲带、碰撞带这三种类型。
大洋中[ ]数万千米的大洋中脊，中间就是裂谷。
地幔物质从这里流出，形成新的洋底岩石，并把两边的板块不断推向两侧，裂谷是洋底的诞生地。
某些陆上裂谷(如东非裂谷)可能会产生了新的海洋。
与裂谷相反，位于大洋边缘的海沟是海洋板块的消亡带。
洋底岩石圈在这里俯冲到大陆岩石圈之下，并潜入软流圈而消失。
另外，如果边界两边都是陆地，这就成为碰撞带。
随着碰撞角度的不同，这里或因挤压而隆起高山，或因剪切而形成断层，或者兼而有之。
1．[ ]恰当的措辞是：A．遍布 B．扩展 C．绵延 D．延伸[解答]正确答案是C。
2．下列判断与文意相符合的一项是：A．板块运动的形式有三种：碰撞、俯冲和裂谷B．板块边界的碰撞或俯冲，和裂谷的情形相反C．裂谷位于海洋中或海洋与陆地的交接处D．碰撞带和俯冲带位于大洋边缘或陆地之上[解答]正确答案是B。
请开始答题：一、阅读以下文字，回答下面的问题。
宽带是传送比特的能力。
宽带每秒钟能够传送大量的比特。
尽管很多人把宽带比喻成水管的直径，但是这样容易使人产生误解，因为获取比特与从花园或者消防水管中饮水并不一样。
我们没有必要连续获取比特(像喝水一样)，即使我们真的这样，这也未必意味着计算机必须连续接收比特。
数字世界带来的最深刻的变化是最小范围内以及最大范围内给人们提供了异步能力。

2002年国家公务员行测考试A类判断推理真题参考答案及解析
2002年国家公务员行测考试A类真题参考答案及解析每道题包含两套图形和可供选取择的4个图形。
这两套图具有种相似性，也存在某种差异。
要求你从四个选项中选择你认为最适膈取代问号的一个正确答案应不仅使两套图形表现出最大的相似性，而且使第二套图形也表现出自己的特征。
[例题][解答]正确答案为D。
因为只有D能使两套图形具有相似性，仅仅元素不同，一个是半圆，一个是半个正方形，但两组图形中元素的排列规律完全相同。
请开始答题：46．47．48．49．50．51．52．53．54．55．46.A 【解析】这是一道图形旋转题。
观察第一套图形发现上面的那个小三角形遵循这一规律：最前面的一个与后面的两个方向相反；下面的那个半圆遵循这一规律：前面的两个与最后面的一个方向相反。
依此规律，第二套图形中，上面的梯形最前面的一个与后面的两个方向相反，下面的梯形前面的两个与最后面的一个方向相反，得到答案为A。
47.C 【解析】第一套图中的后一个图都是由构成前一个图的三条线段相对移动和整体旋转而成；依此规律可以推知，问号处的图形中应只有两条线段是相互垂直的。
48.C 【解析】这是一道图形叠加题。
第一套图的前两个图形叠加保留不重叠的阴影部分，去掉重叠的阴影部分，便得到第三个图形，依此规律得到第二套图的第三个图形为C。
49.C 【解析】观察第一套图发现，第二个图形为第一个图形的左半边，第三个图形为第一个图形的右半边加上第二个图形，依此规律得到第二套第三个图形为C。
50.B 【解析】观察第一套图可发现：后一个图中直线与多边形的交点要少于前一个图中直线与多边形的交点。
依此规律可推出答案为B。
51.C 【解析】这是一道图形旋转题。
观察第一套图发现，将前一个图形中的直角形状的黑色体绕正方形的中心顺时针旋转90度，将小正方形的黑色体绕正方形的中心逆时针旋转90度，这样得到下一个图形；第二套图中，将靠近正方形边线的黑色体绕正方形的中心顺时针旋转90度，再将靠近中心的小正方形黑色体绕中心逆时针旋转90度，这样得到第二个图形，将第二个图形按上述旋转方法旋转即得到第三个图形，答案为C。

2002年国家公务员录用考试《行测》真题(A卷)参考答案及解析
1、【答案】B【解析】A 项扫描仪是在影像处理过程中将照片图案等扫描输入到电脑的一项输入设备。
B 项磁盘驱动器既可读盘，又能将数据写入，因此既可算做输入设备，又可看成输出设备。
C 项键盘是电脑主要的输入设备，可以用来接收使用者的指令和外界的资料等。
D 项显示器是电脑最主要的输出设备，可以将电脑处理后的结果如文字或影像显示出来。
A、C、D 三项均功能单一，只有 B 项既可以作输入设备又可以作输出设备。
故正确答案为 B 2、【答案】C【解析】实际上，烟雾中的颗粒物是肉眼不易察觉的，A 项错误；香烟冒出的蓝色烟雾实际上是香烟的颗粒对蓝色光有较强的散射效应。
按照光的散射定律，白光中的短波成分蓝紫色遭到散射比长波成分红黄色强烈，散射光因短波富集而呈蓝色。
与光的吸收和透射没有关系，BD 项错误。
故答案为 C【拓展】每当大雨初霁、澄清了尘埃的时候，天空总是呈美丽的蔚蓝色，其道理也是蓝紫光的散射。
旭日和夕阳呈红色，则是由于白光中蓝紫色成分被更多散射掉了，在直射的日光中剩余较多的是红黄色的长波成分3、【答案】B【解析】电磁波谱是一系列不同频率辐射的总称。
波段频率从低到高排列的顺序依次是：无线电波、微波、红外光、可见光、紫外光、X-射线、γ-射线。

Part I Reading Comprehension (40%)Directions: There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Passage 1 Questions I to 5 are based on the following passage:In ancient times the most important examinations were spoken, not written. In the schools of ancient Greece and Rome, testing usually consisted of saying poetry aloud or giving speeches.In the European universities of the Middle Ages, students who were working for advanced degrees had to discuss questions in their field of study with people who had made a special study of the subject. This custom exists today as part of the process of testing candidates for the doctor’s degree.Generally, however, modern examinations are written. The written examination, where all students are tested on the same question, was probably not knownuntil the nineteenth century. Perhaps it came into existence with the great increase in population and the development of modern industry. A room full of candidates for a state examination, timed exactly by electric clocks and carefully watched over by managers, resembles a group of workers at an automobile factory. Generally, during examinations teachers and students are expected to act like machines.One type of test is sometimes called an “objective” test. It is intended to deal with facts, not personal opinions. To make up an objective test the teacher writes a series of questions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like correctanswers to students who have not learned the material properly.1. In the Middle Ages students （D. never wrote exams）2. The main idea of paragraph 3 is that （D. examinations are now written and timed）3.The kind of exams where students must select answers are （C. objective）4. Modern industry must have developed （B. around the 19th century）5. It may be concluded that testing （C. has changed since the Middle Ages）Passage 2Questions 6 to 10 are based on the following passage:The market investigation is indispensable to sales promotion. They are as closely related as the lips and teeth, so to speak. What you produce is for sale on the market. It would he impossible to succeed in selling a product without first investigating the market.In the international market, goods on sale coming from countries and suppliers are always facing keen competition. Under such circumstances, they will try everything possible to familiarize themselves with the market conditions. In making investigations, we ought to get information about what similar items the competitors are offering on the market, whatprices they are quoting (报价), what features their products have, who are their regular customers, etc. Then, how can we obtain such information? There are many channels that we can make use of in doing this sort of work. The commercial counselor’s offices of our embassies stationed abroad can help us in making market investigations. Nowadays, our import and export corporations send their trade groups abroad every now and then. One of their purposes is to make market surveys on the spot.Certainly, face-to-face talks with foreign businessmen are also important channels to get market information. The Chinese Export Commodities Fairs and some other fairs of similar nature as well as visits of foreign businessmen provide’ uswith such opportunities. Of course, there are some other ways of making market investigations.6. In making market investigation, one should （A. get enough information concerned）.7. The word “indispensable” in the first line means （B. essential）.8. Which of the following statements is not true?（ D. Production goes before market investigation.）9. Making market investigation is very important because （D. all of the above）.A. in market ,goods on sale are numerousB. every producer is facing keen competitionC. it can greatly promote sales10. All the following are channels to get market information except（B. to promote the quality of our own products ）.Passage 3Questions 11 to 15 are based on the following passage:On November 19, 1863, Abraham Lincoln went to Gettysburg in Pennsylvania to speak at the National Soldiers Cemetery. The Civil War was still going on. There was much criticism of President, Lincoln at the time. He was not at all popular. He had been invited to speak at Gettysburg only Out of politeness. The principal speaker was to beEdward Everett, a famous statesman and speaker of the day. Everett was a handsome man and very popular everywhere.It is said that Lincoln prepared his speech on the train while going to Gettysburg. Late that night , alone in his hotel room and tired out, he again worked briefly on the speech. The next day Everett spoke first. He spoke for an hour and 57 minutes. His speech was a perfect example of the rich oratory of the day. Then Lincoln rose. The crowd of 15,000 people at first paid little attention to him. He spoke for only nine minutes. At the end there was little applause. Lincoln turned to a friend and remarked, “I have failed again.” On the train back to Washington, he said sadly,” That speech was a flat failure, and the people are disappointed.Some newspapers at first criticized the speech. But little by little people read the speech they began to understand better. They began appreciate its simplicity and its deep meaning. It was a speech which only Abraham Lincoln could have made.Today, every American school child learns Lincoln’s Gettysb urg -Address by heart. Now everyone thinks of it as one of the greatest speeches ever given in American history.11. In 1863, Abraham Lincoln was （B. unpopular）12. Lincoln was invited to speak at the National Soldiers Cemetery because he was （C. President of the country）13. It can be inferred from the text that （B. Lincoln was very busy at the time and didn’t have much time to prepare his speech）.14. It was a fact that Lincoln’s speech was （D. not well-received at first）.15. Which of the following statements is NOT true according to the passage?（ D. Lincoln’s Gettysburg Address is the greatest speech ever delivered in the United States.）Passage 4Questions 16 to 20 are based on the following passage:Animals seem to have the sense to eat when they are hungry and they donot eat more than their bodies need. It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant flavor was added to the vitamin-enriched fluid, the rats did seem to develop a taste for it and kept drinking it, even after the vitamins were switched to the clear water. In time, however, they broke the habit and went back to where the necessary vitamins were.In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria feeding arrangement, with a wide selection of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at firstthey showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet.So, in selecting food, rats and babies do seem to know and act on what’s best for them. Apparently, there is a kind of “body wisdom,”which humans soon lose. Most of us do not eat as wisely as we could.
