Directions:There are four passages in this part.Each passage is followed by some questions or unfinished statements.Choose the best answer from the four choices following each question or statement and mark the corresponding letter on your answer sheet.

Passage 1

There is perhaps no other event in the natural world that is as characteristic of a season as a full chorus of spring peepers.It is not only that the voices of living things are calling once more after the long silence of winter,there is something about the atmosphere in which the chorus takes place that epitomizes the season.There is a certain moist smell in the air on rainy spring nights,slow mists rise from rafts of ice floating in dark marshes,everywhere on roads through wet areas the small white forms of migrating spring peepers,wood frogs,green frogs,and pickerel frogs appear,and all around you the air will be filled with a high bell-like ringing,a little like a distant horse-drawn sleigh.That distant chorus is the voice of the spring peeper,a small tree frog no larger than the end of a little finger.Throughout history naturally have referred to it as the voice of spring.

In actuality you may be a long way from the pond or marsh that the peepers are calling from.The voice of spring peepers can carry as much as a mile on still spring nights,and once you learn to recognize the song,there will be nights when it is difficult to escape their incessant calling.The sound will accompany you through spring,a sort of background music to the events that will be taking place around you during the season.

Passage 2

Jean Sibelius fell very much alone because he couldn't accept the music of that day.He believed that one should be able to make for oneself an ideal by reflection,and thought that modern music did not progress because it marked time without moving a step farther.When he began work on his Fifth Symphony,Europe and his beloved Finland were being ravaged by World War I.He wrote in September of 1914.“But I already begin to see dimly the mountain that I shall certainly ascend.God opens his door for a moment and His orchestra plays the Fifth Symphony.”But from the very first he was full of doubts about this work.He wasn't sure whether or not he should have begun on the fifth symphony.He suffered a good deal for having persevered in composing symphonies at a time when practically all composers had turned to other forms of expression.

The Fifth Symphony was completed late in 1915.It was performed on the composer's fiftieth birthday which was declared a national holiday.Sibelius conducted the concert but he was not satisfied with this new work.In October of 1916,he revised the symphony but a performance two months later still did not satisfy him.

41.Why did Jean Sibelius feel alone?

A.Because he realized his limitations as a music composer.

B.Because he couldn't accept the music of that day.

C.Because he lived far from his family.

D.Because all of his friends excluded him from music.

42.What did Sibelius think of modern music?

A.It reflected an ideal.

B.It did not make much progress.

C.It was too progressive.

D.It was not popular.

43.How did Sibelius feel after conducting the Fifth Symphony in 1915?

A.He was uncertain about his work.

B.He thought he was blind.

C.He was satisfied with his conducting.

D.He wasn't happy about his new work.

44.When Europe and Finland were ravaged by World War I,how did he feel about his new work?

A.He began to see the mountains rather than the sea.

B.He was too discouraged by the war to play the Fifth Symphony.

C.He thought he was very stubborn.

D.He felt like continuing Fifth Symphony.

45.How old was he when he conducted the Fifth Symphony for the first time?

A.48 years old.B.49 years old.C.50 years old.D.51 years old.

Passage 3

Petroleum products,such as gasoline,kerosine,home heating oil,residual fuel oil,and

lubricating oils,come from one source-crude oil found below the earth's surface,as well as under large bodies of water,from a few hundred feet below the surface to as deep as 25,000 feet into the earth's interior.Sometimes crude oil is secured by drilling a bole through the earth,but more dry boles are drilled than those producing oil.Pressure at the source or pumping forces crude oil to the surface.

Crude oil wells flow at varying rates,from ten to thousands of barrels per hour.Petroleum products are always measured in 42-gallon barrels.

Petroleum products vary greatly in physical appearance:thin,thick,transparent or opaque,but regardless,their chemical composition is made up of only two elements:carbon and hydrogen,which form compounds called hydrocarbons.Other chemical elements found in union with the hydrocarbons are few and are classified as impurities.Trace elements are also found,but these are of such minute quantities that they are disregarded.The combination of carbon and hydrogen forms many thousands of compounds which are possible because of the various positions and joinings of these two atoms in the hydrocarbon molecule.

The various petroleum products are refined from the crude oil by heating and condensing the vapors.These products are the so-called light oils,such as gasoline,kerosene,and distillate oil.The residue remaining after the light oils are distilled is known as heavy or residual fuel oil and is used mostly for bunting under boilers.Additional complicated refining processes rearrange the chemical structure or the hydrocarbons to produce other products,some of which are used to upgrade and increase the octane (辛烷) rating of various types of gasoline.

46.According to the passage,all the following is true EXCEPT________.

A.crude oil is found below land and water

B.crude oil is always found a few hundred feet below the surface

C.pumping and pressure force crude oil to the surface

D.a variety of petroleum products is obtained from crude oil

47.Many thousands of hydrocarbon compounds are possible because________.A.the petroleum products vary greatly in physical appearance

B.complicated refining processes rearrange the chemical structure

C.the two atoms in the molecule assume many positions

D.the pressure needed to force it to the surface causes molecular transformation 48.Which of the following is TRUE?

A.The various petroleum products are produced by filtration.

B.Heating and condensation produce the various products.

C.Chemical separation is used to produce the various products.

D.Mechanical means such as the centrifuge (离心机) are used to product the various products.

49.Crude oil is brought to the surface by means of________.

A.expansion of the hydrocarbons

B.pressure and pumping

C.vacuum created in the drilling pipe

D.expansion and contraction of the earth's surface

50.Which of the following is not listed as a light oil?

A.Distillate oil B.Gasoline C.Lubricating oil D.Kerosine

Passage 4

University physics is intended for students of science and engineering.Primary emphasis is on physical principles and problem-solving;historical background and specialized practical applications have been given a place of secondary importance.Many worked-out examples and an extensive collection of problems are included with each chapter.

In this new edition,the basic philosophy and outline and the balance between depth of treatment and breadth of subject-matter coverage are unchanged from previous editions.We have tried to preserve those features that users of previous editions have found desirable,while incorporating a number of changes that should enhance the book's usefulness.

The textbook is adaptable to wide variety of course outlines.The entire textbook can be used for and intensive course two or three semesters in length.For a less intensive course,many instructors will want to omit certain chapters or sections to tailor the book to their individual nerds.The arrangement of this edition facilitates this kind of flexibility.

Conversely,however,many topics that were regarded a few years ago as of less importance and were omitted from introductory courses have now come to the fore again in the life sciences,earth and space sciences,and environmental problems.An instructor who wishes to stress these kinds of applications will find this textbook a useful source for discussion of the appropriate principles.

In any case,it should be emphasized that instructors should not feel constrained to work sleight through the book from cover to cover.Many chapters are,of course,inherently sequential in nature,but within this general limitation instructors should be encourage to select among the contents those chapters that fit their needs,omitting material that is not relevant for the objectives of a particular course.

51.Which of the following is NOT mentioned about the new edition?

A.Historical background is given priority;

B.Physical principles and problem-solving are emphasized.

C.Specialized practical applications are considered important.

D.Many worked-out examples are provided.

52.According to the passage,this new edition________.

A.has been made more applicable

B.is easier to learn

C.covers a wider range of subject matter

D.has improved the balance between theory and practice

53.One of the features of this textbook is that________.

A.some contents are dealt with in terms of philosophy

B.it has an outline for each chapter

C.it introduces the physical principles in great depth

D.it can be used for different course arrangements

54.The words “Conversely,however” (Line 1,Para.4) indicate that________.A.many topics can be emphasized though they were not covered in the old edition

B.many topics can be emphasized though they were usually omitted by instructors

C.many topics have been added to the new edition as they were not covered in the old one D.many topics have been added to the new edition though they can omitted by the

instructors

55.To meet the needs of a particular course,the teacher of this book can omit some of the contents provided that________.

A.his selection is based on the request of his students

B.he does not omit any chapter completely

C.his students are particularly intelligent

D.he keeps an eye on the internal relations between the chapters

Ⅳ.Directions:Choose FIVE of the underlined sentences in the passages below and translate them into Chinese.Write your answers on the answer sheet and remember to put down the sentence number before each translated sentence.(15%)

Passage A

Drug abuse in the United States has come to be regarded as one of the most challenging social problems facing the nation.(1)Indeed the very word “drug” excites strong motions,and opinion polls since the late 1960s have shown that the “drug problem” is perceived by most Americans as a major threat to our society particularly to its younger members.

For our purposes,we can define a drug as any chemical that is psychoactive,or capable of modifying a person's behavior through its effect on emotions,thinking,or consciousness.Strictly speaking,many familiar substances such as aspirin or ten are drugs,but when most Americans think of drugs,they have in mind only outlawed substances such as heroin or LSD.(2)A characteristic of many psychoactive chemicals is that they lead to dependence;that is,the user develops a recurrent craving for them.Dependence may be psychological,physical,or both.In the case of psychological dependence,the user feels psychologically discomforted if cut off from the drug.(3)In the case of physical dependence,or addiction,bodily withdrawal symptoms may occur,taking many forms and ranging in severity from slight trembling to fatal convulsions.Users develop a tolerance for some drugs,that is,they have to take steadily increasing amounts to achieve a given level of effect.

The sociologists are interested in why people choose the drugs they do,why some abuse drugs,and why particular societies permit certain drug use.(4)Also of interest is the actual reaction to various forms of drug use,because this reaction serves to define the status of the drug-takers—in some cases,by labeling them as criminals.

Passage B

In the higher education system of the United States,the research universities have played a leading role.Nevertheless,the research universities have too often failed,and continue to fail,their undergraduate populations.(5)Tuition income from undergraduates is one of the major sources of university income,helping to support research programs and graduate education,but the students paying the tuition get in all too many cases,less than their money's worth.Recruitment materials display proudly the world-famous professors,the splendid facilities and the groundbreaking research that goes on within them,but thousands of students graduate without ever seeing the world-famous professors or tasting genuine research.(6)Some of their instructors are likely to be badly trained or even untrained teaching assistants who are groping their way toward teaching technique;some others may be tenured drones who deliver set lectures from yellowed notes,making no effort to engage the bored minds of the students in front of them.

(7)Many students graduate having accumulated whatever number of courses is required,but

still lacking a coherent body of knowledge as to how one sort of information might relate to

others.And too often they graduate without knowing how to think logically,write clearly,or

speak coherently.(8)The university has given them too little that will be of real value beyond a

credential that will help them get their first jobs.And with larger and larger numbers of their peers

holding the same paper in their hands,even that credential has lost much of its potency.

Ⅴ.Directions:The table below shows social and economic indicators for four countries in

1994,according to United Nations statistics.Describe the information shown below in your own

words.What implications do the indicators have for the countries? You should write at least 250

words.(20%)

计算机网络答案-山东大学期末考题目答案

第一章概述 1-3试从多个方面比较电路交换、报文交换和分组交换的主要优缺点。 答:1、电路交换电路交换是一种必须经过“建立连接-通话-释放链接”三个步骤的一条专用物理通路。从建立连接开始,通讯就一直占用信道资源,直到释放。它具有实施性强,时延小,交换设备成本低的优点。同时,其线路利用效率低,通信效率低,不同类型终端之间不可通讯。电路交换适用于信息量大,较长的报文。 2、报文交换报文交换本质上也是存储转发方式,但是它将整个报文从一个结点传到下一个。它的优点是中继电路利用率高,可以多个用户同时在一条线路上传送。缺点在于报文信息量大,时延长,且占用交换机内存较大,不具有实时性。它适用于报文较短,实时性较低的通讯。 3、分组交换分组交换是将报文分组,在每个分组之前加上地址信息,通过路由器经接收,存储,再转发到下一个接口,直到将分组传到目标地址,再去掉地址信息将其重组为完整报文。在分组传输的过程中动态分配传输宽带,逐

段占用通信链路,多个分组数可同时传送。它传输效率高,且保证数据传输有很高可靠性。同时分组排队会造成时延,但比报文交换小,且成本较高。 1-12 因特网的两大组成部分(边缘部分与核心部分)的特点是什么?他们的工作方式各有什么特点? 答:边缘部分由所有连接在因特网上的主机组成,由用户直接使用,进行通信和资源共享。核心部分,是由大量网络和连接这些网络的路由器组成,主要为边缘部分服务提供连通性和交换。边缘部分不同终端上的程序通信方式有客户-服务器方式和对等方式。客户-服务器方式指进行通讯的双方中一方为服务请求方,一方为服务提供方。客户向服务器发送远程服务请求,因此客户程序必须知道服务器程序地址,而服务器只需要被动接受请求,不需要知道客户程序地址,但需要强大硬件和高级操作系统支持。对等方式是双方均可既为服务提供者,也可以为服务请求

Young men will never again go to war as they did in 1914. Millions of people now have seen the effects of a battle. And the result has been a general dislike of war, and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen. Television has also changed politics. The most distant areas can now follow state affairs, see and hear the politicians before an election. Better informed, people are more likely to vote, and so to make their opinion count. Unfortunately, television’s influence has been extremely harmful to the y oung. Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless. They believe that the violence they see is normal and acceptable. All educators ag ree that the “television generations”

计算机网络答案 山东大学期末考题目答案

第一章概述 1-3试从多个方面比较电路交换、报文交换和分组交换的主要优缺点。 答:1、电路交换电路交换是一种必须经过“建立连接-通话-释放链接”三个步骤的一条专用物理通路。从建立连接开始,通讯就一直占用信道资源,直到释放。它具有实施性强,时延小,交换设备成本低的优点。同时,其线路利用效率低,通信效率低,不同类型终端之间不可通讯。电路交换适用于信息量大,较长的报文。 2、报文交换报文交换本质上也是存储转发方式,但是它将整个报文从一个结点传到下一个。它的优点是中继电路利用率高,可以多个用户同时在一条线路上传送。缺点在于报文信息量大,时延长,且占用交换机内存较大,不具有实时性。它适用于报文较短,实时性较低的通讯。 3、分组交换分组交换是将报文分组,在每个分组之前加上地址信息,通过路由器经接收,存储,再转发到下一个接口,直到将分组传到目标地址,再去掉地址信息将其重组为完整报文。在分组传输的过程中动态分配传输宽带,逐段占用通信链路,多个分组数可同时传送。它传输效率高,且保证数据传输有很高可靠性。同时分组排队会造成时延,但比报文交换小,且成本较高。 1-12 因特网的两大组成部分(边缘部分与核心部分)的特点是什么?他们的工作方式各有什么特点? 答:边缘部分由所有连接在因特网上的主机组成,由用户直接使用,进行通信和资源共享。核心部分,是由大量网络和连接这些网络的路由器组成,主要为边缘部分服务提供连通性和交换。边缘部分不同终端上的程序通信方式有客户-服务器方式和对等方式。客户-服务器方式指进行通讯的双方中一方为服务请求方,一方为服务提供方。客户向服务器发送远程服务请求,因此客户程序必须知道服务器程序地址,而服务器只需要被动接受请求,不需要知道客户程序地址,但需要强大硬件和高级操作系统支持。对等方式是双方均可既为服务提供者,也可以为服务请求者。 网络核心部分要想网络边缘部分提供连通性和交换,起关键作用的是路由器,其任务是转发收到的分组,使得边缘部分的每一个终端都能够向其他主机通信。 1-14 计算机网络有哪些常用的性能指标? 答:1、速率:连结在计算机网络上的主机在数字信道上传送数据的速率,单位为b/s(其中 b 为bit,表示一个二进制数字,比特是计算机中数据量的单位) 2、带宽:带宽本来指的是某个信号具有的频带宽度,单位为赫;由于通信的主干线传送的是模拟信号,所以,带宽表示通信线路允许通过的信号频带范围,表示在单位时间内,从网络中的某一点到另一点所能通过的“最高数据率”,单位是比特每秒。 3、吞吐量:表示单位时间内通过某个网络口的数据量,经常用于对现实世界中的网络的一种测量,以便知道实际上到底有多少数据量能通过网络 4、时延:时延指数据从网络的一段传送到另一端所需要的时间。有以下几个部分组成:(1)发送时延从主机发送数据帧的第一个比特算起,到该帧的最后一个比特发送完毕所需要的

山东大学期末考试知识点复习

第七章新闻图片编辑 【知识框架】 【重点难点归纳】 一、新闻图片的种类及其地位 1.报纸上常见的图片种类 (1)照片 新闻照片就是以新闻事件、新闻人物为拍摄对象,再现新闻现场情景的照片,它可以作为独立的新闻报道出现在版面上,也可以配合文字报道一同编发。 (2)漫画 漫画在现代报纸上的使用非常广泛,有根据新闻事实进行艺术加工的新闻漫画,时效性较强,经常刊登在新闻版上;也有反映社会生活现象的社会性漫画,通常刊登在专刊副刊上;还有用来配合文字报道的图解式漫画以及连环漫画、幽默画等。 (3)图示 图示包括统计图表、示意图和新闻地图三类。 统计图表就是将统计数字制成表格图,便于读者集中阅读,一目了然。

示意图不但将统计数字集中绘制成图,而且用形象化的手法表示这些数据所说明的意义。 新闻地图则是根据标准地图,将新闻发生地的地理位置绘制成更加简洁明确的地图。 (4)图饰 图饰一般是用美术图案点缀和烘托报纸的报头、报眉、标题、栏题、版头或版面的其他部位,使整个版面更加美观生动,恰当地运用图饰还能使版面编排思想得到更加充分的体现。 2.图片的地位与作用 (1)纪实性作用 作为独立报道体裁的新闻照片具有再现新闻现场、记载真实瞬间的作用,这类照片成为报纸上不可或缺的重要组成部分。 (2)证实性作用 非独立使用的新闻照片与非新闻照片具有证实文字报道的作用,这类照片对新闻资源的充分发掘,对提高新闻报道的可信度具有重要意义。 (3)解说性作用 图表、示意图、新闻地图、漫画等能够以形象性的符号统计和描绘新闻报道中的某些内容,从而对相对比较枯燥的文字表述进行生动易懂的解释。 (4)装饰性作用 图片的形象性特征使其可以作为文字稿件的美化装饰手段。 (5)视觉冲击性作用 图片的形象性和直观性能够产生强烈的视觉冲击效果,产生巨大的吸引力与震撼力,这是文字报道所难以达到的。

During the twentieth century there has been a remarkable shortening of the proportion of a woman’s life spent in caring for children. A woman marrying at the end of the nineteenth century world probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which custom, opportunity and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty-five and can be expected to live another thirty-five years and is likely to take paid work until retirement at sixty. Even while she has the care of children, her work is lightened by household appliances and convenience foods. The important change in women’s life-pattern has only recently begun to have its full effect on women’s economic p osition. Even a few years ago most girls left school at the first opportunity, and most of them took a full-time job.

Such an imbalance exists when the total value of a country’s imports exceeds that of its exports. For example, if a country buys $25 billion of products from other countries, yet sells only $10 billion of its own products overseas, its trade deficit(贸易逆差)is $15 billion. Many underdeveloped nations find themselves in this position because they lack natural resources or the industrial capacity to use these resources, and thus have to import raw materials or manufactured goods. One effect of a trade deficit is the flow of currency out of a country. In the case of an underdeveloped nation, this can cause many financial difficulties, including failure to meet debt payments and obstacles to creation of an industrial base. Even in the case of a fully developed nation such as the United States, a large trade deficit is a reason for alarm. American products, made by well-paid workers in U.S. industries, cost more to produce than those made in places like Asia, where labor and material costs are much lower. Money spent on foreign products is money not spent on items produced by domestic industries. 6. What does the passage mainly discuss? B
