SECTIONⅢ Reading Comprehension (40 minutes) Par A Directions Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. Text 1 In November 1965, New York was blacked out by an electricity failure. The authorities promised that it would not happen again. Pessimists were certain that it would occur again within five years at the latest. In July 1997, there was a repeat performance which produced varying degrees of chaos throughout the city of eight million people. In 1965, the failure occurred in the cool autumn and at a time of comparative prosperity. In 1997, the disaster was much more serious because it came when unemployment was high and the city was suffering form one of its worst heat waves. In 1965, there was little crime or looting during the darkness, and fewer than a hundred people were arrested. In 1997, hundreds of stores were broken into and looted. Looters smashed shop windows and helped themselves to jewelry, clothes or television sets. Nearly 4,000 people were arrested but far more disappeared into the darkness of the night. The number of policemen available was quite inadequate and they wisely refrained from using their guns against mobs which far outnumbered them and included armed men. Hospitals had to treat hundreds of people cut by glass from shop windows. Banks and most businesses remained closed the next day. The blackout started at 9:30 p.m., when lightning hit and knocked out vital cables. Many stores were thus caught by surprise. The vast majority of New Yorkers , however, were not involved in looting. They helped strangers, distributed candles and batteries, and tried to survive in a nightmare world without traffic lights, refrigerator, elevators, water and electrical power. For twenty-four hours, New York realized how helpless it was without electricity. 46. From the first paragraph, we know that _____ were right. A. the authorities B. the pessimists C. both the authorities and the pessimists D. neither the authorities nor the pessimists 47. In what way was the blackout of 1997 not really a repeat performance? A. There was much more disorder. B. This time the electricity supply failed. C. It was quite unexpected. D. It did not occur within five years of 1965. 48. As far as maintaining the peace was concerned, conditions in 1997 were comparatively ___________. A. more favorable B. less favorable C. uncharged D. improved 49. What caused the blackout in July 1997? A. Excessive heat probably made people switch on too many electrical appliances. B. Because of unemployment, some machines were not in proper working order. C. During a storm, lightning damaged supply cables. D. The passage does not mention the cause. 50. Why did many looters manage to escape? A. The police could not see them in the dark. B. Many of the looters were armed with guns. C. There were not enough policemen to catch them all. D. They were hidden inside big buildings. Test 2 Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and more recently, rubber and plastic and that was where we stuck, in surgical instrument terms, for many years. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and industry, but which was also, in time, to revolutionize the art and science of surgery. The tool is the laser and it is being used by more and more surgeons all over the world, for a year large number of different complaints. The word “laser” means: light amplification by stimulated emission of radiation. As we all know, light is hot, any source of light ------- from the sun itself down to a humble match burning ------ will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam. Experiments with these pinpoint beams showed researchers that different energy sources produce beams that have a particular effect on certain living cells. It is now possible for eye surgeons to operate on the back of human eye without harming the front of the eye, simply by passing a laser beam right through the eye-ball. No knives, no stitches, no unwanteddamage----a true surgical wonder. Operations which once left patients exhausted and in need of long period of recovery time now leave them feeling relaxed and comfortable. So much more difficult operations can now be tired. The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps some cancers will be treated with laser in a way that makes surgery not only safer but also more effective. Altogether, tomorrow may see more and more information coming to light on the diseases which can be treated medically. 51. Which of the following would be appropriate to describe the instruments of surgical operations up until 1960s? A. Traditional. B. Complicated C. Remarkable. D. Revolutionary 52. What do we find after the development of the laser in the 1960s? A. Industrial revolution brought surgery changed greatly. B. Medical help became available for industrial workers. C. The study of art went through a complete revolution. D. Human being’s methods in surgery changed greatly. 53. The reason why the laser beam is very strong is that ____________. A. it is artificially illuminated B. it is made up of a concentrated beam of light C. it sends out heat in all directions. D. its heat is increased by the heat of the sun 54. After the use of the laser beam, surgeons can perform operation which __________. A. leave their patients with negative effects B. can treat only human eye diseases C. do little damage to their patients D. make their patients need a long time to recover 55. The rapid development of laser techniques has meant that __________. A. surgery is likely to improve considerably B. in another ten years we shall be able to cure cancer C. in future all the diseases can certainly be cured D. operations will be performed more complicatedly in the future Text 3 Urban life has always involved a balancing of opportunities and rewards against dangers and stress; its motivating force is, in the broadest sense, money. Opportunities to make money mean competition and competition is stressful; it is often most intense in the larges cities, where opportunities are greatest. The presence of huge numbers of people inevitably involves more conflict, more traveling, the overloading of public services and exposure to those deviants and criminals who are drawn to the rich pickings of great cities. Crime has always flourished in the relative anonymity of urban life, but today’s ease of movement makes its control more difficult than ever; there is much evidence that is extent has a direct relationship to the size of communities. City dwellers may become trapped in their homes by the fear of crime around them. As a defense against these developments, city dwellers tend to use various strategies to try and reduce the pressures upon themselves; contacts with other people are generally made brief and impersonal; doors are kept locked; telephone numbers may be ex-directory; journeys outside the home are usually hurried, rather than a source of pleasure. There are other strategies, too, which are positively harmful to the individuals, for example, reducing awareness through drugs or alcohol. Furthermore, all these defensive forms of behavior are harmful to society in general; they cause widespread loneliness and destroy the community’s concern for its members. Lack of informal social contact and indifference to the misfortunes of others, if they are not personally known to oneself, are amongst the major causes of urban crime. Inner areas of cities tend to be abandoned by the more successful and left to those who have done badly in the competitive struggle or who belong to minority groups; these people are then geographically trapped because so much economic activity has migrated to the suburbs and beyond. Present day architecture and planning have enormously worsened the human problems of urban life. Old established neighborhoods have been ruthlessly swept away, by both public and private organizations, usually to be replaced by huge, ugly, impersonal structures. People have been forced to leave their familiar homes, usually to be re-housed in tower blocks which are drab, inconvenient, and fail to provide any setting for human interaction or support. This destruction of established social structures is the worst possible approach to the difficulties of living in a town or city. Instead, every effort should be made to conserve the human scale of the environment, and to retain familiar landmarks. 56. According to the author, living in a city causes stress because there are so many people who are_________________. A. in need of help B. naturally aggressive C, likely to commit crime D. anxious to succeed 57. The author thinks that crime is increasing in cities because _______________. A. criminals are difficult to trace in larges populations B. people do not communicated with their neighbors C. people feel anonymous there D. the trappings of success are attractive to criminals 58. According to the article, what is the worst problem facing people living in cities? A. Crime B. Finding somewhere to live C. Social isolation。

言语理解争议题一锤定音系列之2009年国考三——错误答案都是阅读理解能力不足的体现“一锤定音”系列主要讲解历年公务员考试行测言语理解争议题，前面几期分别讲述了2013年各地新考试题、历年国考等言语理解存在争议的试题。

这些文章讨论的都是市面上考生疑问最多、各机构答案定错的试题，各位可对照手头资料查看答案是否有误。

言语理解争议题“一锤定音”系列将陆续梳理国考、联考，以及一些独立考查省份言语模块定错答案、给错解析或争议较大的试题。

在这里你将看到最准确的答案、最易懂的解析。

下面要讲的是2009年国考的一道逻辑填空，这道题争议很大，不同的机构有不同的答案。

之所以选这道题是因为它将言语理解试题的核心要点很好的呈现出来，仔细看完这篇文章你会有较大收获。

2009年国考例题：托马斯•弗里德曼认为获取信息的性改变了人类的思考方式，就好像计算器发明以后计算好的人不再占明显优势，记忆力好也不再作为评判人聪明的标准。

填入画横线部分最恰当的一项是( )。

A. 便捷必然B. 公平客观C. 对称绝对D. 广泛首要先看两种不同的答案解析版本1：答案A。

解析：由后文的“计算器发明以后计算好的人不再占明显优势”可以看出这里强调的是获取信息的快捷、容易，故可首先排除B、C。

再看第二空，这里是说评判聪明的标准，由常识可知，记忆力的好坏从来不是评判聪明的第一标准，故可排除D，最恰当的选项应为A。

版本2：答案B。

解析：此题突破口在第一空，材料用“计算机问题”和“记忆力问题”来举例证明是获取信息的哪种特性改变了人类的思考方式。

根据“不再占明显优势”可以看出应填“公平”。

因为计算器发明后，计算速度比人脑快，只要大家都有一个计算器，就不会显出谁优谁劣，在获取信息的时候就都是公平的了。

科技发展让这种不对等越来越小，变得越来越公平。

作者强调的正是这种机会的对等。

所以排除A、C、D项，选B项。

再看第二个空，记忆力好是评价人聪明的一个“客观”标准，“客观”放在此处符合语境，且语意通顺。

1．Mr. Han and his brother are from China; they______speak Chinese.A．allB．bothC．either正确答案：B解析：本题考查的是不定代词的用法。

all表示三者以上的所有，both表示两者都，either表示两者其中之一。

因为此处是“两个人都…”的意思，所以用both。

故B正确。

2．--I haven’t seen Tom for a long time. --He______to Boston. He went there last Monday.A．goesB．has goneC．is going正确答案：B解析：本题考查的是现在完成时的用法。

现在完成时态表示一个过去发生的动作在过去已经完成，但对现在有影响或结果。

同时，强调的就是这一影响或结果。

构成是have/has+ 动词过去分词。

故B正确。

3．The workers plan to build a bridge there,______?A．are theyB．do theyC．1 don’t they正确答案：C解析：本题考查的是反意疑问句的用法。

反意疑问句(The Disjunctive Question)即附加疑问句，由两部分组成：前一部分是一个陈述句，后一部分是一个简短的疑问句，两部分的人称时态应保持一致。

反意疑问句是前肯后否，前否后肯：1．陈述部分肯定式+疑问部分否定式2．陈述部分否定式+疑问部分肯定式。

因为本题中前半部分是肯定，所以后半部分应该是否定。

故C正确。

[原文]In a normal recession, the to-do list is clear. Copies of Keynes are dusted off, the Fed lowers interest rates, the president and Congress cut taxes and hike spending. In time, purchasing, production and loans perk up, and Keynes is placed back on the shelf. No larger alterations to the economy are made, because our economy, but for the occasional bump in the road, is fundamentally sound.This has been the drill in every recession since World War II.Republicans and Democrats argue over whose taxes should be cut the most and which projects should be funded, but, under public pressure to do something, they usually find some mutually acceptable midpoint and enact a stimulus package. Even in today's hyperpartisan Washington, the odds still favor such a deal.This time, though, don't expect that to be the end of the story -- because the coming recession will not be normal, and our economy is not fundamentally sound. This time around, the nation will have to craft new versions of some of the reforms that Franklin Roosevelt created to steer the nation out of the Great Depression[参考译文] 平常的经济萧条一旦来临，大家都明确应该马上着手做哪些事情：重新翻开尘封已久的凯恩斯的著作，联邦政府调低利息率，总统和国会开始减税，增加财政支出。

20222023学年上学期第一次阶段性测试卷A卷（人教版）八年级物理·全解全析一、单项选择题：本题共10小题，每小题3分，共30分。

1．（2022·江苏扬州·八年级期末）2020年12月17日，嫦娥五号返回器从空中返回地面时，说“嫦娥五号”返回器是运动的，所选参照物是（）A．返回器携带的月球样品B．地球表面C．返回器上的照相机D．返回器上的计算机【答案】B【解析】“嫦娥五号”返回器从空中返回地面的过程中，返回器相对于它携带的样品、照相机以及计算机的位置都没有发生变化，故以它们为参照物，返回器都是静止的，以地球表面为参照物时，返回器的位置不断发生变化，此时返回器是运动的，故B符合题意，ACD不符合题意。

故选B。

2．（2022·四川成都·八年级期末）如图所示为甲、乙两个小球向右运动过程的频闪照片。

它表示两小球在相等的时间间隔所处的位置，则对甲、乙两个小球的运动情况，判断正确的是（）A．小球甲做变速运动，小球乙做匀速运动B．小球甲做匀速运动，小球乙做变速运动C．小球甲、乙都做匀速运动D．小球甲、乙都做变速运动【答案】B【解析】甲球频闪照片中两点间距一直不变，做的是匀速直线运动；乙球频闪照片中两点间距越来越大，故做的是变速运动；所以小球甲做匀速直线运动，小球乙做变速运动，故ACD错误，B正确。

故选B。

故选A 。

4．（2022·云南红河·八年级期末）如图是甲、乙两物体的s ﹣t 图像，下列说法正确的是（ ）A ．从图中可看出甲比乙运动得快B ．第5s 时甲乙相遇C ．乙一直以5m/s 速度做匀速直线运动D ．甲的速度为15m/s【答案】B【解析】AC ．由图像知，甲是一条过原点的直线，说明甲通过的路程与其时间成正比，即甲保持匀速直线运动；前3s ，乙是一条过原点的直线，所以做匀速直线运动；3s 后乙的位置没有变化，所以处于静止状态，即乙是先匀速直线运动后静止；前3s ，相同时间内乙通过的路程大于甲通过的路程，所以前3s 乙比甲运动得快；3s 后，甲比乙运动得快，故AC 错误；B ．由图像可知，5s 时，甲乙通过的距离相等，因此第5s 时甲乙相遇，故B 正确；D ．由图像可知，5s 内甲通过的路程为15m ，则甲的速度15m 3m/s 5ss v t ===故D错误。

In the days of Napoleon the same wind which would have carried his transports across the Channel might have driven away the blockading （封锁）fleet. There was always the chance，and it is that chance which has excited and befooled （愚弄）the imaginations of many continental tyrants. Many are the tales that are told. We are assured that novel methods will be adopted，and when we see the originality of malice （怨恨），the ingenuity of aggression，which our enemy displays，we may certainly prepare ourselves for every kind of novel stratagem （战略）and every kind of brutal and treacherous （奸诈）maneuver （花招）。

Such as on a jet plane. The symptom of jet lag can be quite varied, and may include loss of appetite, nausea, headache, fatigue, insomnia, or even mild depression. Here are a few tips for you to avoid jet lag, or cope if you are stricken by the condition. First, adjust your biological rhythm several days before your departure, and develop a plan to start switching to the time zone of your destination. For instance, if you will be flying from New York to Paris, where it is 6 hours later, get up one hour earlier for a couple of days, then 2 hours earlier, then 3 hours earlier, I will try to at least get half way to your new time zone. Turn lights on during day time in your destination, and off during the night time. Second, during the time of your adjustment, especially during the flight, drink plenty of water. If you are not a big water fan, drink some other fluid that is not high in sugar, carbonation and caffeine~ avoid junk food, salty food and caffeine, and alcohol on the plane. Of course I say that, but I always have a couple of drinks during the flight. If you do that, just be sure to drink as much water between drinks as possible. Thirdly, when you arrive in your destination, try to resist the urgeto nap during the day time. Get outside, during the daylight hours, even it is just to sit in a caf6 and relax. Try to get a good night sleep for the 1st couple of nights. The key is to reset your body’s natural clock and to get enough rest. Finally, when you return home, use some of the same tactics above to return to your previous time zone.35．A．A flight over time zones.B．A loss of one’s characters.C．A symptom of leg problems.D．A condition of sleep disorders.正确答案：D36．A．Six hours:B．Seven hours.C．Eight hours.D．Nine hours.正确答案：A37．A．Avoid junk food, salty foods, caffeine and alcohol.B．Drink as little water as possible between meals.C．Take drinks with less sugar, carbonation or caffeine.D．Always have other fluid on the plane.正确答案：C38．A．Sleep as soon as possible.B．Nap even during daytime.C．Get a good night’s sleep.D．Relax yourself in a cafe.正确答案：C听力原文：F: Come on Mr. Anderson, take a seat.M: Good morning, doctor.F: Now let’s get a few details.

How do you like your new university? I remember your mom had wanted you to go to London University so that you can live at home and walk or cycle to attend the lectures.M: Well, you know I didn’t go to London University after all. My new university is on the suburbs of an ancient cathedral city and it is almost 8 miles from the city center. The university is planned on the so called American campus system. That is to say, students live in halls of residence grouped around the main university buildings.F: You mean you live, eat and study within the university proper?M: Yes, I like it. Because we are a real community. We’ve got comfortable common rooms and bars. We arrange dances and parties. We’ve got clubs, theater groups, choirs and so on. And we’ve got an orchestra. I played the drums in it. By the way, how about your university days, Betty?F: I rented a house with two other girls in the middle of the city about ten minutes walk from the university. The house is falling to pieces. It is damp and there is no proper heating. M: That sounds awful. I couldn’t work in a place like yours.

We’ve got an electrician living next door, who is always coming in and mending our cooker and electric fires. We could try to get into one of the halls of the residents. But we prefer to be independent. It’s nice to belong to the city and to do things outside the university.M: What sort of things do you do outside the university?M: Well, there is a group of us who go and help in a home for handicapped children. And I sing in the city bar “Choir”. We get on well with the local people, not like you in that suburban district.W: Well, I like history. And my university is one of the best universities for that subject. Besides, it is an ancient city with a lot of historical relics and sightseeing spots.
