⼀、单项选择题:1~45⼩题,每⼩题2分,共90分。
下列每题给出的四个选项中,只有⼀个选项是符合题⽬要求的。
请在答题卡上将所选项的字母涂⿊。
对于题⽬的答案有疑义的,可以进⼊勤思考研论坛提问或者关注勤思考研的微博。

基本观点是:第⼀,当代资本主义的学校教育不是⼀种民主的建制和解放的⼒量,⽽是维护现实社会的不公平和不公正的⼯具,是造成社会差别、社会歧视和社会对⽴的根源;第⼆,教育是与社会相对应的,有什么样的社会政治、经济和⽂化,就有什么样的学校教育机构,社会的政治意识形态、⽂化样态、经济结构都强烈低制约着学校的⽬的、课程、师⽣关系、评价⽅式等,学校教育的功能就是再⽣产出占主导地位的社会政治意识形态、⽂化关系和经济结构;第三,批判教育学的⽬的就是要揭⽰看似⾃然事实背后的利益关系,帮助教师和学⽣对⾃⼰所处的教育环境及形成教育环境的诸多因素敏感起来,即对他们进⾏“启蒙”,以达到意识“解放”⽬的,从⽽积极地寻找克服教育及社会不平等和不公正的策略;第四,教育现象不是中⽴的和客观的,⽽是充满着利益纷争的,教育理论研究不能采取唯科学主义的态度和⽅法,⽽要采⽤实践批判的态度和⽅法。
从题⼲的⾓度出发,选择D。
2.如下现象属于教育范畴的是 A. 爸爸针对⼩明懦弱的个性设法训练⼩明如何以⽛还⽛报复欺侮者 B. 妈妈指导⼩明在与他⼈冲突中如何保护⾃⼰ C. ⽼师严格管理以保护⼩明等弱⼩学⽣不再受欺负 D. ⼩明在与同学的多次冲突中逐渐学会了如何与⼈和睦相处 【参考答案】B 【勤思考研解析】教育的定义具有⼴义和狭义的区分,⼴义的教育指的是,凡是有⽬的的地增进⼈的知识技能,影响⼈的思想品德,增强⼈的体质的活动,不论是有组织的或是⽆组织的,系统的或是零碎的,都是教育。

二、(9分,每小题3分) 阅读下面癿文字,完成5~7题。 警惕汞污染 1953年,日本水俣湾附近发现了一种“怪病”,称为“水俣病”。这种病症最实出现在猫身上,病猫步态丌 稳,抽搐、麻痹,甚至跳海而死。丌丽,陆续发现了患这种病症癿人。患者步履蹒跚,手足麻痹乃至变 形,神经错乤甚至死亡。后来发现,这丌是传染病,而是工业废水排放污染造成癿公害病。水俣湾一家 化工厂生产氯乙烯呾醋酸忆烯使用了含汞癿催化剂,排放癿废水丨含有大量癿汞。其丨有癿是甲基汞, 有癿是无机汞,而无机汞会不水体戒水生物癿有机物反应生成甲基汞。甲基汞癿脂溶性非常强,可以在 生物体内逐渐富集幵通过食物链最终迚入人体,被肠胃吸收,侵害人癿丨枞神经细胞。公叵呾政府对水 俣病癿认定叧考虑直接接触甲基汞所导致癿症状,而这种症状不甲基汞通过食物链迚入人体所导致癿症 状丌完本相同。因此,叧有部分水俣病患者获得认定。 水体丨汞污染是人类健庩癿隐患。因为水丨癿微 量汞,经过水丨食物链(如:浮游植物浮游动物小鱼大鱼)癿逐级转秱,在食物链顶级生物体内可以富 集到数千至数十万倍。以美国金枟鱼罐头为例,1953年含汞量为0.08PPM[注],到了2005年就增长 至1.79PPM。对以鳌鱼呾鲸为主要食物来源癿法罗群岛居民癿追踪调查发现,他们癿血汞含量可能是全 丐界人群丨最高癿,达到6PPM。鱼类体内癿汞主要为甲基汞,其百分比随着鱼龄增加而增加,一年生 癿鱼所含汞丨癿甲基汞癿31%—35%,8—12年癿鱼所含汞丨癿甲基汞为67%—100%。在一般情况下调查 呾监测鱼类癿含示量,对亍了解水域汞污染程度十分必要。 目前全球人为活动向大气排放癿汞达2000 吨/年。汞径容易蒸发到大气丨,幵丏能够随着穸气团作全球范围癿迁秱,在大气丨停留几丧月甚至一 年。在丌同癿条件下,它会发生沉陈,幵在当地食物链生物体内聚积。由亍汞癿这种属性,它被联合国 环境觃划署列为全球性污染物,是除了温室气体外唯一一种对全球范围产生影响癿化孜物质。 我国是汞 生产呾消费大国,十分重规汞污染防治研究。有研究表明:丨国汞污染癿健庩影响途徂不其他国家丌同, 丌能照搬欧美研究成果评价丨国汞污染情况,如在北美呾北欧地区,某些鱼类体内癿汞浓度具有一定癿 指标性意丿,但我国贵州即使在汞污染较严重癿地区,鱼体内汞含量却相对较低。另有研究发现:汽车 尾气丨癿汞迚入到穸气丨后,可以被植物吸收,因此路旁植物丨汞癿含量要高亍公园丨癿植物;北京市 汞污染癿主要来源是煤呾汽油燃烧癿汞释放、化工厂癿汞排放,贵阳市癿汞污染原因则是土壤高汞背景 值以及原煤汞含量高。 垃圾焚烧是汞污染癿又一丧主要来源。垃圾丨癿汞主要来自电池、体温计、日光 灯等,如果能对含汞废弃物采取比一般生活垃圾更严格癿处理措施,将有利亍减少汞污染。 [注]PPM:即百万分乀一。
2012年国家公务员考试《行测》真题卷答案及解析
“十二五”规划的起止时间:2011—2015 年。
A 项错误,2010 年 4 月 8 日,我国首辆高速磁悬浮国产化样车在成都实现交付。
该样车由中航工业成都飞机工业 (集团) 有限公司制造,标志着该企业已经具备了磁浮车辆国产化设计、整车集合和制造能力;B 项错误,2009 年初厦门大学福建省医学分子病毒学研究中心和养生堂北京万泰药业有限公司研制出我国第一种拥有核心自主知识产权的基因工程疫苗——重组戊型肝炎疫苗;C 项错误,2010 年 8 月 26 日上午,科学技术部与国家海洋局联合宣布,国家高技术研究发展计划 (863 计划) 重大专项——我国第一台自行设计、自主集成研制的“蛟龙号”载人潜水器 3000 米级海上试验取得成功,最大下潜深度达到 3759 米,并创造了水下和海底作业 9 小时零 3 分的记录;D 项正确,2011 年 5 月 13 日国家测绘局正式对外发布,历时 3 年科技攻关,打破西方技术壁垒,由中国测绘科学研究院牵头承担的“机载多波段多极化干涉 SAR 测图系统 (简称‘机载 SAR 测图系统’) ”的研制取得全面成功。
故正确答案为 D。
A 项表述正确,“十二五”规划强调要“坚持最严格的耕地保护制度” ,“从严控制各类建筑占用耕地”;B项表述正确,“十二五”规划中提到要“推进植树造林,新增森林面积 1250 万公顷”;C 项表述错误,“十二五”规划在“推动能源生产和利用方式变革“中提到要“推进能源多元清洁发展”,可见 C 项“提高化石能源的比重”表述有误;D 项表述正确,“十二五”规划第二十五章提到,要“坚持保护优先和自然修复为主,加大生态保护和建设力度,从源头上扭转生态环境恶化趋势”。
本题为选非题,故正确答案为 C。
本题相关知识点:化石能源是一种碳氢化合物或其衍生物,它由古代生物的化石沉积而来,是一次能源。
化石燃料不完全燃烧后,都会散发出有毒气体,却是人类必不可少的燃料。
化石能源所包含的天然资源有煤炭、石油和天然气。
2012年考研英语二真题答案解析完整版
详解1.【答案】B 从空后的句子“他们解放的人们”可以看出,空前的句子表示的应该是参加了第二次大战的男人和女人。
只有serve有“服兵役”的意思,所以选B。
其他都不符合题意。
2.【答案】B空内信息应该是与hero“英雄”意思相对,后面的分句说他背井离乡,经历了很多苦难,显然这里应该是说由普通人平凡人(common man)成长为英雄,所以选B。
3.【答案】A 本题考查的是词语的搭配关系,承担战争带来的负担,应该用动词bear或shoulder,所以这里选A,bore。
4.【答案】A necessities表示“生活必需品”,空外信息food和shelter(食物和住宿)这些就是维持生存最起码的条件。
Facilities是设备设施,commodities商品,properties财产,均不符合题意。
5.【答案】C not…but,“不是,而是”表转折,不是自愿兵,也没有高的报酬,而是一个普通人。
所以选C。
6.【答案】D这道题主要考查介词的搭配。
根据up______(the best trained, best equipped, fiercest, most brutal).enemies可以知道是起来反抗敌人,所以选D选项against。
7.【答案】C GI。
在军事上是Government Issue 的缩略语,所以,GL。
这个符号就是象征着这个全称Government Issue。
选C。
8.【答案】A 该句意思为,GI。

Part II Reading comprehension (skimming and scanning)Universities Branch OutAs never before in their long history, universities have become instruments of national competition as well as instruments of peace. They are the place of the scientific discoveries that move economies forward, and the primary means of educating the talent required to obtain and maintain competitive advantage. But at the same time, the opening of national borders to the flow of goods, services, information and especially people has made universities a powerful force for global integration, mutual understanding and geopolitical stability.In response to the same forces that have driven the world economy, universities have become more self-consciously global: seeking students from around the world who represent the entire range of cultures and values, sending their own students abroad to prepare them for global careers,offering course of study that address the challenges of an interconnected world and collaborative (合作的)research programs to advance science for the benefit of all humanity.Of the forces shaping higher education none is more sweeping than the movement across borders. Over the past three decades the number of students leaving home each year to study abroad has grown at an annual rate of 3.9 percent, from 800,000 in 1975 to 2.5 million in 2004.Most travel from one developed nation to another, but the flow from developing to developed countries is growing rapidly. The reverse flow, from developed to developing countries, is on the rise, too. Today foreign students earn 30 percent of the doctoral degrees awarded in the United States and 38 percent of those in the United Kingdom. And the number crossing borders for undergraduate study is growing as well, to 8 percent of the undergraduates at America‘s best institutions and 10 percent of all undergraduates in the U.K.In the United States,20 percent of the newly hired professors in science and engineering are foreign-born, and in China many newly hired faculty members at the top research universities received their graduate education abroad.Universities are also encouraging students to spend some of their undergraduate years in another country. In Europe, more than 140,000 students participate in the Erasmus program each year, taking courses for credit in one of 2,200 participating institutions across the continent. And in the United States, institutions are helping place students in the summer internships (实习)abroad to prepare them for global careers. Yale and Harvard have led the way, offering every undergraduate at least oneinternational study or internship opportunity—and providing the financial resources to make it possible.Globalization is also reshaping the way research is done. One new trend involves sourcing portions of a research program to another country. Yale professor and Howard Hughes Medical Institute investigator Tian Xu directs a research center focused on the genetics of human disease at Shanghai‘s Fudan University, in collaboration with faculty colleagues from both schools. The Shanghai center has 95 employees and graduate students working in a 4,300-square-meter laboratory seminars with scientists from both campuses. The arrangement benefits both countries; Xu’s Yale lab is more productive, thanks to t he lower costs of conducting research in China, and Chinese graduate students, postdoctors and faculty get on-the-job training from a world -class scientist and his U.S. team.As a result of its strength in science, the United States has consistently led the world in the commercialization of major new technologies, from the mainframe computer and the integrated circuit of the 1960s to the Internet infrastructure (基础设施)and applications software of the 1990s.the link between university-based science and industrial application is often indirect but sometimes highly visible: Silicon Valley was intentionally created by Stanford University, and Route 128 outside Boston has long housed companies spun off from MIT and Harvard. Around the world, governments have encouraged copying of this model, perhaps most successfully in Cambridge, England, where Microsoft and scores of other leading software and biotechnology companies have set up shop around the university.For all its success, the United States remains deeply hesitant about sustaining the research -university model. Most politicians recognize the link between investment in science and national economic strength, but support for research funding has been unsteady. The budget of the National Institutes of Health doubled between 1998 and 2003,but has risen more slowly than inflation since then. Support for the physical sciences and engineering barely kept pace with inflation during that same period. The attempt to make up lost ground is welcome, but the nation would be better served by steady, predictable increases in science funding at the rate of long-term GDP growth, which is on the order of inflation plus 3 percent per year.American politicians have great difficult recognizing that admitting more foreign students can greatly promote the national interest by increasing international understanding. Adjusted for inflation, public funding for international exchanges and foreign-language study is well below the levels of 40 years ago, in the wake ofSeptember 11,changes in the visa process caused a dramatic decline in the number of foreign students seeking admission to U.S. universities, and a corresponding surge in enrollments in Australia, Singapore and the U.K. Objections from American university and the business leaders led to improvements in the process and reversal of the decline, but the United States is still seen by many as unwelcoming to international students.Most Americans recognize that universities contribute to the nation‘s well-being through their scientific research, but many fear that foreign students threaten American competitiveness by taking their knowledge and skills back home. They fail to grasp that welcoming foreign students to the United States has two important positive effects: first, the very best of them stay in the States and—like immigrants throughout history—strengthen the nation; and second, foreign students who study in the United States become ambassadors for many of its most cherished (珍视)values when they return home. Or at least they understand them better. In America as elsewhere, few instruments of foreign policy are as effective in promoting peace and stability as welcoming international university students.1. From the first paragraph we know that present-day universities have become ________.A)more popularized than ever beforeB)in-service training organizationsC)a powerful force for global integrationD)more and more research-oriented2.

The National Endowment for the Arts released “Reading at Risk” last year, a study showing that adult reading47 have dropped 10 percentage points in the past decade, with the steepest drop among those 18 to 24. “Only one half of young people read a book of any kind in 2002. We set the bar almost on the ground. If you read one short story in a teen—ager magazine, that would have 48 ,” laments a director of research and analysis. He49 the loss of readers to the booming world of technology, which attracts would—be leisure readers to E—mail, IM chats, and video games and leaves them with no time to cope with a novel.“These new forms of media undoubtedly have some benefits,” says Steven Johnson, author of Everything Bad Is Good for You.Video games50 problem—solving skills; TV shows promote mental gymnastics by 51 viewers to follow complex story lines. But books offer experience that can't be gained from these other sources, from52 vocabulary to stretching the imagination. “If they're not reading at all,” says Johnson, “that's a huge problem.”In fact, fewer kids are reading for pleasure. According to data53 last week from the National Center for Educational Statistic's long—term trend assessment, the number of 17—year—olds who reported never or hardly ever reading for fun54 from 9 percent in 1984 to 19 percent in 2004. At the same time, the55 of 17—year—olds who read daily dropped from 31 to 22.This slow but steady retreat from books has not yet taken a toll on reading ability. Scores for the nation's youth have56 constant over the past two decades with an encouraging upswing among 9—year—olds. But given the strong apparent correlation between pleasure reading and reading skills, this means poorly for the future.A. percentB. remainedC. roseD. ratesE. percentageF. countedG. relievedH. presentI. BelievingJ. releasedK. forcing L. improve M. Styles N. building O. attributesSection BPassage OneQuestions 57 to 61 are based on the following passage.There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among “situations vacant”, alth ough it does not offer anyone a job, and sometimes it appears among “situations wanted”, although it is not placed by someone looking for a job, either. What it does is to offer help in applying for a job.“Contact us before writing your application”, or “Make use of our long experience in preparing your curriculum vitae or job history”, is how it is usually expressed. The growth and apparent success of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right.There was a time when job seekers simply wrote letters of application. “Just put down your n ame, address, age and whether you have passed any exams”, was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest.Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. “Your search is over. I am the person you are looking for”, was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job interview.There is no doubt, however, that it is increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.57. The new type of advertisement which is appearing in newspaper columns.A)informs job hunters of the opportunities availableB)promises to offer useful advice to those looking for employmentC)divides available jobs into various typesD)informs employers of the people available for work58. Nowadays a demand for this specialized type of service has been created because. A)there is a lack of jobs available for artistic peopleB)there are so many top level jobs availableC)there are so many people out of workD)the job history is considered to be a work of art59. In the past it was expected that first job hunters would.A)write an initial letter giving their life historyB)pass some exams before applying for a jobC)have no qualifications other than being able to read and writeD)keep any detailed information until they obtained an interview60. Later, as one went on to apply for more important jobs, one was advised to include in the letter.A)something that would distinguish one from other applicantsB)hinted information about the personality of the applicantC)one's advantages over others in applying for the jobD)an occasional trick with the aggressive approach61. The curriculum vitae has become such an important document because.A)there has been an increase in the number of jobs advertisedB)there has been an increase in the number of applicants with degreesC)jobs are becoming much more complicated nowadaysD)the other processes of applying for jobs are more complicatedPassage TwoQuestions 62 to 66 are based on the following passage.In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time,rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent—controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low—paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages. Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if “other things are equal”. Economists do not agree on some of the predictio ns. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.62. There is the possibility that setting maximum rent may.A)cause a shortage of apartmentsB)worry those who rent apartments as homesC)increase the profits of landlordsD)encourage landlords to invest in building apartment63. According to the critics, rent control.A)will always benefit those who rent apartmentsB)is unnecessaryC)will bring negative effects in the long runD)is necessary under all circumstances64. The problem of unemployment will arise.A)if the minimum wage is set too highB)if the minimum wage is set too lowC)if the workers are unskilledD)if the maximum wage is set65. The passage tells us.A)the relationship between supply and demandB)the possible results of government controlsC)the necessity of government controlD)the urgency of getting rid of government controls66. Which of the following statements is NOT true?A)The results of economic decisions can not always be predicted.B)Minimum wage can not always protect employees.C)Economic theory can predict the results of economic decisions if other factors are not changing.D)Economic decisions should not be based on economic theory.Part ⅤCloze (15 minutes)Rumor is the most ___67___way of spreading stories—by passing them on from mouth___68___mouth.

2012年12月英语四级真题及答案解析完整版
2012年12月英语四级真题及答案解析完整版Part I Writing【标准版】Nothing Succeeds Without a Strong WillNothing runs smoothly in our life. To achieve things successfully, a strong will is essential. Life is like a Marathon. Many people can’t get to the terminal. This is not bec ause they are lack of vitality but because their will of success is not strong enough.To take quitting smoking as an example, some regard it as a piece of cake. They make up their minds to quit it in the morning, but in the evening they feel that the smell of cigarettes is tempting. Their throats are sore, their mouths are thirsty, and their hands are shaking. After the painful mental struggle, they tell themselves that “One cigarette is enough. Just take one, and the next day I will quit it.” By doing this, they surrender to their weak will. In the end, they have quitted smoking “a hundred times”, but in no time they succeed.Just like quitting smoking, nothing succeeds without a strong will. To be successful in one’s life, a strong will means that you know where you go and you will persist on the road you choose. Undoubtedly success belongs to those who overcome their weak will and who hang in there until the last minute.【文章点评】本文属于话题类作文,只看题目“Nothing Succeeds without a strong will”考生会觉得比较抽象,难以下手。

2012年高考真题—(陕西卷)word详细答案解析版
2012年普通高等学校招生全国统一考试语文新课标详解一、现代文阅读(9分,第小题3分)阅读下面的文字,完成l~3题。
“黑箱”是控制论中的概念,意为在认识上主体对其内部情况全然不知的对象。
“科技黑箱“的含义与此有所不同,它是一种特殊的存贮知识、运行知识的设施或过程,使用者如同面对黑箱,不必打开,也不必理解和掌握其中的知识,只需按规则操作即可得到预期的结果。
例如电脑、手机、摄像机、芯片,以及药品等,可以说,几乎技术的全部中间和最终成果都是科技黑箱。
在科技黑箱的生产过程中,科学知识是基础,价值观和伦理道德则对科学知识进行选择。
除此以外,科技黑箱中还整合了大量人文的、社会的知识,并且或多或少渗透了企业文化和理念。
这样,在电脑或手机中就集成了物理学、计算机科学、管理学、经济学、美学,以及对市场的调研和政府的相关政策等知识。
科技黑箱是特殊的传播与共享知识的媒体,具有三大特点。
首先,它使得每一个使用者——不仅牛顿,都能直接“站在巨人的肩上”继续前进。
试想,如果要全世界的电脑使用者都透彻掌握电脑的工作原理,掌握芯片上的电子理论,那需要多少时间?知识正是通过科技黑箱这一途径而达到最大限度的共享。
如今,计算机天才、黑客的年龄越来越小,神童不断出现,他们未必理解计算机的制作过程就能编写软件、破译密码。
每一代新科技黑箱的出现,就为相对“无知识”的年轻一代的崛起与赶超提供了机会。
其次,处在相对低端的科技黑箱往往与语境和主体无关,而处于高端的科技黑箱则需满足特定主体在特定场合乃至心理的需要。
人们很少能对一把锤子做什么改进,而使用一个月后的电脑则已经深深地打上了个人的印记,这就说明,在认识变得简单易行之时,实践变得复杂和重要。
最后,当科技为我们打开一扇又一扇门的时候,我们能拒绝它的诱惑不进去吗?而一旦进去,我们的行为能不受制于房间和走道的形状吗?表面上是使用者在支配科技黑箱,然而科技黑箱却正在使用者“不知情”的情况下,对使用者施加潜移默化的影响,也就是说使用者被生产方对象化了。

Each passage is followed by 5 questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the best one and mark your answer on the ANSWER SHEET.Passage OneWe are all busy talking about and using the Internet, but how many of us know the history of the Internet?Many people are surprised when they find that the Internet was set up as recently as the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way the computer network system would keep on working all the time.At first the Internet was only used by the government, but in the 1970s, universities, hospitals and banks began to use it, too. However, computers were still very expensive and the Internet was difficult to use. At the beginning of the 1990s, computers became cheaper and easier to use. And scientists developed software that made Internet “surfing” more convenient.Today it is easy to get online and it is said that millions of people use the Internet every day.16. The Internet was set up in __B__.A. 1960B. the 1960sC. 1970D. the 1970s17. Computer networks didn’t work well at first because __D.A. computers were large and expensiveB. computers couldn’t send information fastC. computers didn’t f it into the same networkD. if one computer failed, the whole network stopped18. Which of the following was the first to use the Internet? AA. Governments.B. Universities.C. Banks.D. Hospitals.19. Which of the following statements is true? CA. People use the Internet mainly to send emails.B. Computers are now more costly than ever before.C. Computers were costly and hard to use until the early 1990s.D. In the 1970s the Internet was easy to use but computers were costly.20. The best title for the passage is _C__.A. The Future of the InternetB. The History of ComputersC. The History of the InternetD. Convenient Internet SurfingPassage TwoAlan Chang was a handsome young man with good manners.One morning he was walking along a street on his way to an appointment. He did not want to be early or late. He had forgotten to put on his watch so he went up to a man who was waiting for a taxi.“Excuse me, sir,” he said, very politely, “but could you tell me the time?”The man, who was very well-dressed and looked quite rich, said nothing. He did not even look at Alan. Alan spoke to him again. “Excuse me, sir,” he said, “but could you please tell me what time it is?”This time the man looked at him, but he did not speak and looked quickly away. Alan thought to himself: well, he can hear me; he must be just rude. So Alan asked again, “Why wouldn’t you tell me the time, sir?”The man turned towards him and said, “Put yourself in my shoes. I am standing here waiting for a taxi. You come up to me and ask me for the time. If I tell it to you, you will thank me. I will say ‘That’s all right.’ You may then say ‘It’s a beautiful day,’ to which I may reply ‘Yes, I like these sunny winter days.’ Before we know what is happening we have a friendly conversation. You are a pleasant, polite young man, so when my taxi comes, I offer you a ride. You accept. We talk. I like you. You like me. I invite you to my home. You meet my daughter. She is a very pretty girl. You are a good-looking man. You like each other. Soon you fall in love. You want to marry. Now do you understand my problem?”Alan shook his head. “No, sir, I’m sorry, I don’t. Everything you have said seems very natural to me.”“Exactly,” the man said, “and I do not want my daughter to marry a man who is too poor to buy a watch. Good morning to you.” And with these words he hurried away.21. Why did Alan ask the man what time it was? CA. He was toolate. B. He was very early.C. He had left his watch home.D. He wanted to meet the man’s daughter.22. What did Alan think of the man when he would not tell him the time? AA. He was impolite.B. He was deaf.C. He was stupid.D. He spoke no English.23. What did the man mean by the underlined part “Put yourself in my shoes”? DA. Don’t interruptme. B. My shoes hurt me.C. Come and try my shoes.D. Try to understand me.24. What kind of a man was Alan Change in the man’s opinion? BA. A thief.B. A poor man.C. A cheat.D. A rich man.25. The story is mainly about A.A. how rude a person can beB. how one thing leads to anotherC. where a person can’t tell the timeD. why you shouldn’t speak to strangersPassage ThreeWhat are the beauties of Hawaii? Let’s start with four.The beach, famous for its water temperature, air temperature and waves, is the first beauty. There are hundreds of miles of beaches on the twenty islands of Hawaii. They are thought to be among the finest beaches in the world.Then, what do you think would be the second beautiful thing? It is volcanoes (火山), of course. These volcanoes are not just a part of the islands; they made the islands in the first place. Because of them the islands are still growing.What would be the third thing of beauty that the first visitor to Hawaii would not ice? It probably wouldn’t be just one thing, but many things: all the wonderful fruits and flowers of the islands. Sugar cane, bananas and pineapples are Hawaii’s biggest exports. Sugar cane has been growing in Hawaii for a thousand years. As for pineapples, the islands producemore than any other places in the world, which has made Dole Company the biggest fruit-packing company in the world.The fourth and most beautiful thing about Hawaii is the people who live there. The Hawaiians never rush, and perhaps this is because they care more for human life than they care for the machine. There is an old Hawaiian law that a man can go to sleep in the middle of the road if he wants to. What makes the people of Hawaii so beautiful is their feeling about people. There are 64 different combinations of races on the islands, and they all live in peace. They believe “Above all nations is humanity.” That is the most beautiful thing of all.26. According to the passage, Hawaii is made up of B__.A. one islandB. twenty islandsC. sixty-four islandsD. hundreds of islands27. Why are the volcanoes so special to the islands? BA. They are not a part of the islands.B. They actually made the islands.C. They are the first in the world.D. They are growing.28. What has made Dole Company the biggest fruit-packing company in the world? DA. Sugar.B. Sugar cane.C. Bananas.D. Pineapples.29. The people in Hawaii are the most beautiful thing because _ D_.A. they had a peaceful historyB. they can sleep in the middle of the roadC. there are 64 different races on the islandsD. they care more for people than anything else30. According to the passage, “above all nations is humanity” might mean __C .A. not all nations have humanityB. humanity is as important as a nationC. humanity has no national boundariesD. all human beings should live in peacePassage FourThere is a measurable relation between how much a person learns and his attitude toward the subject to be learned. When faced with a difficult learning task, one path to success is to concentrate on the positive aspects of the subject matter. If a student has a boring teacher, one solution is to look for the positive aspects of completing the course, regardless of how boring the teacher happens to be. To accomplish this might require a private tutor or some independent reading, but with the right attitude, success is possible.Over-achievers – students who do better than their test scores show –usually have a positive interest toward learning. They may learn some things more slowly, and they may make more efforts, but, to compensate (补偿), they are often better at applying what they have learned. As long as they do not have emotional problems, they are successful.Under-achievers – those who function below their ability shown by test scored – often tend to allow a few negative factors to affect them. Because of their negative attitudes, they sometimes become unfairly critical of teachers. They allow themselves to get bored when it is not necessary. In short, their attitudes often cause them to learn less than over-achievers.If you learn to replace a negative attitude toward learning with something more positive, you are on the road to achieving almost any goal you desire. For example, if you realize a personal computer with a word processor would improve your performance, but have an attitude that keeps telling you that a computer is difficult to operate, you tend to make all kinds of excuses. In short, you resist making full use of a terrific tool, simply because your negative attitude prevents you from learning.31. What does the author think a student should do if he has a boring teacher? DA. Look for a new course.B. Be critical of the teacher.C. Complete the course with a good score.D. Have a right attitude toward the teacher.32.
