For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and blacken the corresponding letter on the ANSWER SHEET with a pencil. Questions 41 to 45 are based on the following passage:Prior to the 20th century, many languages with small numbers of speakers survived for centuries. The increasingly interconnected modern world makes it much more difficult for small language communities to live in relative isolation, a key factor in language maintenance and preservation.It remains to be seen whether the world can maintain its linguistic andcultural diversity in the centuries ahead. Many powerful forces appear to work against it :population growth, which pushes migrant populations into the world's last isolated locations; mass tourism; global telecommunications and mass media; and the spread of gigantic global corporations. All of these forces appear to signify a future in which the language of advertising, popular culture, and consumer products become similar. Already English and a few other major tongues have emerged as global languages of commerce and communication. For many of the world's peoples, learning one of these languages is viewed as the key to education, economic opportunity, and a better way of life.Only about 3,000 languages now in use are expected to survive the coming century. Are most of the rest doomed in the century after that Whether most of these languages survive will probably depend on how strongly cultural groups wish to keep their identity alive through a native language. To do so will require an emphasis on bilingualism(mastery of two languages). Bilingual speakers could use their own language in smaller spheres---at home, among friends, in community settings---and a global language at work, in dealings with government, and in commercial spheres. In this way, many small languages could sustain their cultural and linguistic integrity alongside global languages, rather than yield to the homogenizing (同化的)forces of globalization.Ironically, the trend of technological innovation that has threatenedminority languages could also help save them. For example, some experts predict that computer software translation tools will one day permit minority language speakers to browse the Internet using their native tongues.Linguists are currently using computer-aided learning tools to teach a variety of threatened languages.For many endangered languages, the line between revival and death is extremely thin. Language is remarkably resilient (有活力的),however. It is not just a tool for communicating, but also a powerful way of separating different groups, or of demonstrating group identity. Many indigenous(原生的,土著的)communities have shown that it is possible to live in the modern world while reclaiming their unique identities through language.41.Minority languages can be best preserved in __________.A.an increasingly interconnected worldB.maintaining small numbers of speakersC.relatively isolated language communitiesD.following the tradition of the 20th century42.According to Paragraph 2, that the world can maintain its linguistic diversity in the future is _______.A.uncertain B.unrealistic C.foreseeable D.definite43.According to the author, bilingualism can help_________.A.small languages become acceptable in work placesB.homogenize the world's languages and culturesC.global languages reach home and community settingsD.speakers maintain their linguistic and cultural identityputer technology is helpful for preserving minority languages in that it_________.A.makes learning a global language unnecessaryB.facilitates the learning and using of those languagesC.raises public awareness of saving those languagesD.makes it easier for linguists to study those languages45.In the author's view, many endangered languages are________. A.remarkably well-kept in this modern worldB.exceptionally powerful tools of communicationC.quite possible to be revived instead of dying outD.a unique way of bringing different groups togetherQuestions 46 to 50 are based on the following passage:Everyone,it seems,has a health problem 。

Choose the one that you think is the best answer.TEXT AIf you like the idea of staying with with a family,living in house might be the answer.Good landladies---those who are superb cooks and launderers,are figures as popular in fiction as the bad ones who terrorize their guests and overcharge them at the slightest opportunity.The truth is probably somewhere between the two extremes.If you are lucky,the food will be adequate, some of your laundry may be done for you and you will have a reasonable amount of comfort and companionship .For the less fortunate ,house rules may restrict the freedom to invite friends to vistit,and shared cooking and bathroom facilities can be frustrating and row-provoking if tidy and untidy guests are living under the same roof.The same disadvantages can apply to flat sharing,with the added difficulties that arise from deciding who pays for what,and in what proportion.One person may spend hours on the phone,while another rarely makes calls. If you want privacy with a guest , how do you persuade the others to go out; how do you persuade them to leave you in peace,especially if you are student and want to study?Conversely,flat sharing can be cheap,there will always be someone to talk to and go out with,and the chores,in theory,can be shared.81.According to the passage ,landladies are ________ually strict.B.always mean.C.adequately competent.D.very popular with their guests.82.What is the additional disadvantage of flat sharing ?A.Problems of sharing and paying.B.Differences in living habits.C.Shared cooking and bathroom facilities.D.Restriction to invite friends to visit.83.What is NOT mentioned as a benefit of flat sharing?A.Rent is affordableB.There is companionship.C.Housework can be shared.D.There is peace and quiet.TEXT B(1) Travelling through the country a couple of weeks ago on business,I waslistening to the talk of the late UK writer Douglas Adams’ masterwork “The Hitchhiker’s Guide to the Galaxy” on the radio and thought-I know,I’ll pick up the next hitchhikers I see and ask them what the state of real hitching is today in Britain.(2)I drove and drove on main roads and side roads for the next few days and never saw a single one.(3)When I was in my teens and 20s ,hitchhiking was a main form of long-distance transport.The kindness or curiosity of strangers took me all over Europe,North America,Asia and southern Africa,Some of the lift-givers became friends ,many provided hospitality on the road.(4)Not only did you find out much more about a country than when traveling by train or plane ,but there was that element of excitement about where you would finish up that night.Hitchhiking featured importantly in Western culture.It has books and songs about it .So what has happened to it?(5)A few years ago ,I asked the same question about hitching in a column ofa newspaper.Hundreds of people from all over the world responded with their view on the state of hitchhiking .(6)Rural Ireland was recommended as a friendly place for hitching,as was Quebec,Canada-“if you don’t mind being criticized for not speaking French”.(7)But while hitchhiking was clearly still alive and well in some places ,the general feeling was that throughtout much of the west it was doomed.(8)With so much news about crime in the media,people assumed that anyone on the open road without the money for even a bus ticket must present a danger.But do we need to be so wary both to hitch and to give a lift?(9)In Poland in the 1960s,according to a Polish woman who e-mail me ,"the authorities introduced the Hitchhiker’s Booklet.The booklet contained coupons for drivers,so each time a driver picked somebody ,he or she received a coupon.At the end of the season,drivers who had picked up the most hikers were rewarded with various prizes.Everyone was hitchhiking then”.(10)Surely this is a good idea for society.Hitchhiking would increase respect by breaking down barriers between strangers.It would help fight global warming by cutting down on fuel consumption as hitchhikers would be using existing fuels.It would also improve educational standards by delivering instant lessons in geography ,history,politics and sociology.(11)A century before Douglas Adams wrote his “Hitchhiker’s Guide”,another adventure story writer,Robert Louis Stevenson, gave us that what should be the hitchhiker’s motto:"To travel hopefully is a better thing than to arrive.” What better time than putting a holiday weekend into practice. Either put it to the test yourself, or help out someone who is trying to travel hopefully with thumb outstretched.84. In which paragraph(s) does the writer comment on his experience of hitchhiking?A. (3)B. (4)C. (3) and (4)D. (4) and (5)85. What is the current situation of hitchhiking?A. It is popular in some parts of the world.B. It is popular throughout the west.C. It is popular only in the North Amercia.D.It’s still popular in Poland.86. What is the writer’s attitude towards the practice in Poland?A. Critical.B. Unclear.C. Somewhat favourable.D. Strongly favourable.87. The writer has mentioned all the following benefits of hitchhiking EXCEPTA. promoting mutual respect between strangers.B. increasing one’s confidence in strangers.C. protecting enviroment.D. enriching one’s knowledge.88."Either put it to the test yourself…”in Paragraph (11) meansA. to experience the hopefulness.B. to read Adams’ book.C. to offer someone a lift.D.to be a hitchhiker.TEXT CI am afraid to sleep. I have been afraid to sleep for the last few weeks. I am so tired that, finally, I do sleep, but only for a few minutes. It is not a bad dream that wakes me ; it is the realiry I took with me into sleep . I try to think of something else.Immediately the woman in the marketplace comes into my mind.I was on my way to dinner last night when I saw her . She was selling skirts. She moved with the same ease and loveliness I often saw in the women of Laos. Her long black hair was as shiny as the black silk of the skirts she was selling . In her hair, she wore three silk ribbons, blue ,green, and white. They reminded me of my childhood and how my girlfriends and I used to spend hours braiding ribbons into our hair.I don’t know the word for “ribbons”, so I put my hand to my own hair and , with three fingers against my head , I looked at her ribbons and said “Beautiful.”She lowered her eyes and said nothing. I wasn’t sure if she understood me (I don’t speak Laotian very well).I looked back down at the skirts. They had designs in them: squares and triangles and circles of pink and green silk. They were very pretty. I decided to buy one of those skirts, and I began to bargain with her over the price. It is the custom to bargain in Asia. In Laos bargaining is done in soft voices and easy moves with the sort of quiet peacefulness.She smiled, more with her eyes than with her lips. She was pleased by the fewwords I was able to say in her language, although they were mostly numbers, and she saw that I understood something about the soft playfulness of bargaining. We shook our heads in disagreement over the price; then, immediately, we made another offer and then another shake of the head. She was so pleased that unexpectedly, she accepted the last offer I made. But it was too soon. The price was too low. She was being too generous and wouldn’t make enough money. I moved quickly and picked up two more skirts and paid for all three at the price set; that way I was able to pay her three times as much before she had a chance to lower the price for the larger purchase. She smiled openly then, and, for the first time in months, my spirit lifted. I almost felt happy.The feeling stayed with me while she wrapped the skirts in a newspaper and handed them to me. When I left, though, the feeling left, too. It was as though it stayed behind in the marketplace. I left tears in my throat. I wanted to cry. I didn’t , of course.I have learned to defend myself against what is hard; without knowing it, I have also learned to defend myself against what is soft and what should be easy.I get up, light a candle and want to look at the skirts. They are still in the newspaper that the woman wrapped them in. I remove the paper, and raise the skirts up to look at them again before I pack them. Something falls to floor. I reach down and feel something cool in my hand. I move close to the candlelight to see what I have. There are five long silk ribbons in my hand, all different colours. The woman in the maketplace! She has given these ribbons to me!There is no defense against a generous spirit, and this time I cry, and very hard, as if I could make up for all the months that I didn’t cry.89.According to the writer, the woman in the marketplaceA refused to speak to her.B was pleasant and attractive.C was selling skirts ribbons.D recognized her immediately.90. Which of the following in NOT corret?A. The writer was not used to bargaining.B. People in Asia always bargain when buying things.C. Bargaining in Laos was quiet and peaceful.D.The writer was ready to bargain with the woman.91. The writer assumed that the woman accepted the last offer mainly because the womanA. thought that the last offer was reasonable.B.thought she could still make much money.C.was glad that the writer knew their way of bargaining.D. was tired of bargaining with the writer any more.92. Why did the writer finally decide to buy three skirts?A.The skirts were cheap and pretty.B.She liked the patterns on the skirts.C.She wanted to do something as compensation.D.She was fed up with further bargainning with the woman.93.When the writer left the marketplace, she wanted to cry, but did not becauseA. she had learned to stay cool and unfeeling.B. she was afraid of crying in public.C.she had learned to face difficulties bravely.D. she had to show in public that she was strong.94. Why did the writer cry eventually when she looked at the skirts again?A.she suddently felt very sad.B.she liked the ribbons so much.C.she was overcome by emotion.D.she felt sorry for the woman.TEXT DThe kids are hanging out. I pass small bands of students, on my way to work these mornings.They have become a familiar part of the summer landscape.These kids are not old enough for jobs. Nor are they rich enough for camp. They are school children without school. The calendar called the school year ran out on them a few weeks ago. Once supervised by teachers and principals, they now appear to be “self care”.Passing them is like passing through a time zone. For much of our history, after all, Americans arranged the school year around the needs of work and family. In 19th century cities, schools were open seven or eight hours a day, 11 months a year.In rural America, the year was arranged around the growing season. Now, only 3 percent of families follow the agricultural model, but nearly all schools are scheduled as if our children went home early to milk the cows and took months off to work the crops. Now, three-quarters of the mothers of school-age children work, but the calendar is written as if they were home waiting for the school bus.The six-hour day, the 180-day school year is regarded as something holy. But when parents work an eight-hour day and a 240-day year, it means something different. It means that many kids go home to empty houses. It means that, in the summer, they hang out.“We have a huge mismatch between the school calendar and the realisties of family life,”says Dr. Ernest Boyer ,head of the Carnegie Foundation for the Advancement of Teaching.Dr. Boyer is one of many who believe that a radical revision of the school calendar is inevitable."School, whether we like it or not, is educational. It always has been.”His is not popular idea. Schools are routinely burdened with the job of solving all our social problems. Can they be asked to meet the needs of our work and family lives?It may be easier to promote a longer school year on its educational merits and, indeed, the educational case is compelling. Despite the complaints and studies about our kids’ lack of learning, the United State still has a shorter school year than any industrial nation. In most of Europe, the school year is 220 days. In Japan, it is 240 days long. While classroom time alone doesn’t produce a well-educated。

道路几何线形要素的构成是否合理,线形组合是否协调,对交通安全有很大影响。
(1)平曲线。
平曲线与交通事故关系很大,曲率越大事故率越高,尤其是曲率大于10以上时,事故率急剧增加。
(2)竖曲线。
道路竖曲线半径过小时,易造成驾駛人视野变小,视距变短,,从而影响驾驶人的观察和判断,易产生事故。
(3)坡度。
据前苏联调查资料,平原、丘陵与山地3类道路交通事故率分别为7%,18%和25%,主要原因是下坡来不及制动或制动失灵。
(4)线形组合。
交通安全的可靠性不仅与平面线形、纵坡有关,而且与线形组合是否协调有密切的关系,即使线形标准都符合规范,但组合不好仍然会导致事故增加。

下列关于高压开关的切断能力的说法,正确的包括(A.负荷开关能切断负荷电流,不能切断短路电流 D.断路器能切断负荷电流和短路电流 E.隔离开关不能切断负荷电流和短路电流)【解析】电路的短路电流远远大于负荷电流,只有断路器既能切断短路电流又能切断负荷电流;负荷开关不能切断短路电流,只能切断负荷电流;隔离开关只起到显示明显的断点的作用,不能切断负荷电流和短路电流。
所以正确选项是ADE。
超声探伤技术是利用超声波检查固体内部结构缺陷,它具有(B.在高密度固体中损失小 D.不但可以探伤固体,还可以检查管道中流体的流量 E.检测中常用的超声波频率为1〜5MHz)等特点。
【精析】超声波探伤技术,检测中常用的是 1~5MHz的超声波。
与声波相比,超声波具有方向性好、波长短、在高密度固体中损失小及在不同密度介质的界面上反射差异大等特点。
因此,利用超声波可以对所有固体材料进行探伤和检测。
它常用来检查内部结构的裂纹、搭接、夹杂物、焊接不良的焊缝、锻造裂纹、腐蚀坑以及加工不适当的塑料压层等,还可以检查管道中流体的流量、流速以及泄露等。
留设隔离岩(煤)柱是矿井防治水的重要措施之一。
影响隔离岩(煤)柱尺寸的主要因素是开采矿体的机械强度、厚度和(B.地下含水层的水压和水量) 【精析】为防止煤(矿)层开采时各种水流进入井下,在受水威胁的地段留一定宽度或厚度的煤 (矿)柱。
防水煤(矿)柱尺寸的确定应考虑到含水层的水压、水量、所开采煤(矿)的机械强度、厚度等因素及有关规定,并通过实践综合确定。
根据原岩(煤)体应力状态不同,冲击地压(岩爆)可分为3类:重力型冲击地压、构造应力型冲击地压、中间型或重力一构造型冲击地压。
井工煤矿采煤方法虽然种类较多,但归纳起来,基本上可以分为壁式、柱式两大体系。
留矿采矿法:工人直接在矿房暴露面下的留矿堆上作业,自下而上分层回采,每次采下的矿石靠自重放出1/3左右,其余暂留在矿房中作为继续上采的工作台。
矿房全部回采后,暂留在矿房中的矿石再行大量放出,即大量放矿。
这种采矿方法适用于开采矿石和围岩稳固、矿石无自燃性、破碎后不结块的急倾斜矿床。
下列防治煤与瓦斯突出的技术措施中,属于区域性措施的是(A.预抽煤层瓦斯)【精析】目前区域性措施主要有3 种,即预留斧采保护层、大面积瓦斯预抽放、控制预裂爆破;局部性措施有许多种,如卸压排放钻孔、深孔或浅孔松动爆破、卸压槽、固化剂、水力冲孔等。
土方开挖:(1)应针对土质的类别、基坑的深度、地下水位、施工季节、周围环境、拟采用的机具来确定升挖方案;(2)开挖的基坑(槽)设计深度如比邻近建筑物、构筑物的基础深时,应采取边坡支撑加固措施,并在施工中进行沉降和位移动态观测;(3)根据基坑的深度、土质的特性和周围环境确定对基坑的支护方案;(4)根据选定的基坑支护方案进行设计和验算;(5)根据所采用的开挖方案编制操作程序和规程;(6)绘制施工图; (7)制定回填方案。
在基坑或管沟开挖时,常因受场地的限制不能放坡,或者为了減少挖填的土方量,缩短工期以及防止地下水渗入基坑等要求,可采用设置支撑与护壁桩的方法。
当开挖较大较深(>6m) 基坑,临近有建筑,不允许支撑有较大变形时,应采用挡土护坡桩支撑。
各类模板拆除的顺序和方法,应根据模板谩计的规定进行。
如果模板设计无规定时,可按先支的后拆,后支的先拆顺序进行。

某可燃气爆炸下限为A,其在某场所空气中的含量为B,假设B = 0. 5A,那么,此时该场所可燃气环境爆炸危险度R 为 (50%) 【精析】可燃气环境爆炸危险度具体的计算公式为:输油站的生产区、办公区、生活区应有明显的分界标志,并设有“严禁烟火”等醒目的防火标志,机动车辆进入生产区,其排气管应装有阻火器;在生产从事生产、检修、施工和抢修的职工,应穿戴防静电防护服、安全鞋和使用防爆工具,禁止使用手机等非防爆通信工具;生产区内不应使用汽油、轻质油、苯类溶剂等擦地板、设备和衣物;生产区域内应做到无油污、无杂草、无其他易燃易爆物。
站内的设备、管网做到完好无渗漏;集输泵房、阀组间、计量间、集输罐区应装有可燃气体浓度报警器。
TN系统分为TN—S,TN—C—S, TN—C三种类型。
TN—S系统是PE线与N线完全分开的系统;TN— C一S系统是干线部分的一段线与JV线共用为PEN线,后一段 PE戴与N线分开的系统;TN — C系统是干线部分PE线与N线完全共用的系统。
应当注意,支线部分的PE线是不能与N线共用的。
我国《压力容器安全技术监察规程》根据容器压力的高低、介质的危害程度以及在使用中的重要性,将压力容器分为以下三类:三类容器。
符合下列情况之一者为三类容器:(1)高压容器;(2)中压容器(毒性程度为极度和高度危害介质);(3)中压贮存容器(易燃或毒性程度为中度危害介质,且设计压力与容积之积PV≥10MPa· m3;(4)中压反应容器(易燃或毒性程度为中度危害介质,且PV≥0.5MPa· m3;(5)低压容器(毒性程度为极度和高度危害介质,且PV≥0.2MPa· m3;(6)高压、中压管壳式余热锅炉;(7)中压搪玻璃压力容器;(8)使用强度级别较高(抗拉强度规定值下限≥540MPa的材料制造的压力容器;(9)移动式压力容器,包括铁路罐车(介质为液化气体、低温液体)、罐式汽车(液化气体、低温液体或永久气体运输车)和罐式集装箱(介质为液化气体、低温液体)等;(10)球形贮罐(容积V≥50m3);(11)低温液体贮存容器(V≥5m3)二类容器。
符合下列情况之一且不在第1款之内者为二类容器:(1)中压容器;(2)低压容器(毒性程度为极度和高度危害介质);(3)低压反应容器和低压贮存容器(易燃介质或毒性程度为中度危害介质);(4)低压管壳式余热锅炉;(5)低压搪玻璃压力容器。
一类容器。
低压容器且不在第1第2款之内者。
压力容器中化学介质毒性程度和易燃介质的划分可参照有关规定,或依据下述原则:最高容许浓度<0.1mg/m3为极度危害(Ⅰ级);最高容许浓度0.1~<1.0mg/m3为高度危害(Ⅱ级);最高容许浓度1.0~<10mg/m3 ,为中度危害(Ⅲ级);最高容许浓度≥10mg/m3 ,为轻度危害毒性介质(Ⅳ级)。
而介质与空气的混合物爆炸下限<10%或爆炸上限与下限之差>20%者为易燃介质。
水运交通事故的外界.条件因素包括: (1)视距降低;(2)气象恶劣给船舶带来不可抗拒的自然灾害;(3)礁石、浅滩及水中障碍物必给船舶航行带来影响;(4)航路的自然条件和交通密度的影响(5)灯塔、航路标志出现故障、航行资料失效;(6)外部因素引起船舶导航设备失效。
