Clothes can be bought ready 36, washing can go to the laundry, food can be bought cooked, canned or 37 ,bread is baked and delivered by the baker, milk 38 on the doorstep, meals can be had at the restaurant ,the works' canteen and the school dining-room.It is unusual now for father to 39 his trade or other employment at home, and his children rarely, 40, see him at his place of work. Boys are therefore seldom trained to 41 their father's occupation and in many towns they have a fair wide 42 of employment and so do girls. The young wage-earner often earns good money, and soon acquires a feeling of 43 independence. In textile areas it has 44 for mothers to go out to work, 45 this practice has become so widespread that the working mother is now a not unusual 46 in a child's home life the number of married women in employment having more than doubled in the last twenty-five years. With mother earning and his old children-draw 47 wages, father is seldom the 48 figure that he still was at the beginning of the Century. 49 mother work, economic advantages increase, but children lose something of 50 value if mother's employment prevent her from being home to greet them when they return from school.36.

We also direct emotive language at other people to persuade them to believe as we do or to do as we wantthem to do; and of course, other people direct emotive language at us to get us to believe or to do what they want.We are subjected to a constant stream of persuasion day in, day out, at home and in school, on the radio and on television. It comes from parents and teachers, from preachers and politicians, from editors and commentators, but, most of all, of course, from advertisers. Most of this persuasion is expressed in emotive language and is intended to appeal to our feelings rather than to be weighted up by our powers of reasoning.We should look at the motives behind all this persuasion. Why do they want to persuade us ? What do they want us to do ? We are not thinking very clearly unless we try to see through the veil of words and realize something of the speaker's purpose.An appeal to emotion is in itself neither good or bad. Our emotions on the highest levels and from the best of motives. A case in point is Churchill's wartime speeches: whatever people thought of Churchill as a politician, they were united behind him when he spoke as a national leader in those dark days their feelings responded to his call for resolution and unity.It is a characteristic of social groups that the members have a feeling of personal attachment to the group -- to the family in earliest childhood and extending later to the school, the team, the church, the nation, in patterns that vary from time to time. Hence a speaker from our group will find in us feelings to which he can readily and genuinely appeal, whether our reaction is favorable or not. We are at least open to the appeal and we appreciate the context in which it is made.51. The major functions of emotive language discussed in the passage are to______A. extend our powers of reasoning and carry out a purposeB. advertise and produce the wanted social effectsC. show one's Feelings and appeal to those of othersD. make others believe in us and respond to our feeling52. It is suggested in the third paragraph of this passage that we______A. should keep a cool head when subjected to persuasions of various kindsB. need to judge whether a persuasion is made for good or badC. have to carefully use our emotive languageD. should avoid being easily seen through by an appeal from others53. The source from which emotive language flows upon us in its greatest amount is______A. the mass mediaB. the educational institutionsC. the religious circlesD. the advertising business54. Churchill is mentioned in the passage as______A. an example of how people weighted up persuasion with reasoningB. a national leader who brought out people's best feelingsC. a positive example of appealing to people's emotionD. a politician who has been known as a good speaker55. What is NOT mentioned as relevant to our emotions in this passage ?A. SocialB. Personal experienceC. The personality of national leadersD. Religious belief56. It can be inferred from the passage that a persuasive speaker must______.A. find out what group his audience is attached toB. vary his speech patterns from time to timeC. know how to adapt his way of speaking to the needs of the audienceD. be aware whether the listeners are favorable to his opinion or notPassage TwoAs goods and services improved, people were persuaded to spend their money on changing from old to new, and found the change worth the expense. When an airline equipped itself with jets, for example, its costs (and therefore air fare) would go up, but the new planes meant such an improvement that the higher cost was justified. A new car (or wireless, washing machine, electric kettle)made life so much more comfortable than the old one that the high cost of replacement was fully repaid. Manufacturers still cry their wares as persuasively as ever, but are the improvements really worth paying for? In many field things have now reached such a high standard of performance that further progress is very limited and very, very expensive. Airlines, for example, go to enormous expense in buying the latest prestige jets, in which vast research costs we might lose the chance of cutting minutes away from flying times : but wouldn't it be better to see air fares drop dramatically, as capital costs become relatively insignificant ? Again, in the context of a 70 m.p.h. limit, with platoons of cars traveling so densely as to control each other's speeds, improvements in performance are virtually irrelevant; improvements in handling are unnecessary, as most production cars grip the road perfectly;and comfort has now reached a very high level indeed. Small improvements here are unlikely to be worth the thousands that anybody replacing an ordinary family car every two years may ultimately have spent on them. Let us instead have cars --- or wireless, electric kettles, washing machines, television sets-- which are made to last, and not to be replaced. Significant, progress is obviously a good thing; but the insignificant progression from model-change to model-change is not.57. The author obviously is challenging the social norm that______A. it is important to improve goods and servicesB. development of technology makes our life more comfortableC. it is reasonable that prices are going up all the timeD. slightly modified new products are worth buying58. According to this passage, air fares may rise because______.A. people tend to travel by new airplanesB. the airplane has been improvedC. the change is found to be reasonableD. the service on the airplane is better than before59. According to the author, passengers would be happier if they ______.A. could fly in the latest model of reputable planesB. could get tickets at much lower pricesC. see the airlines make vital changes in their servicesD. could spend less time flying in the air60. When manufacturers have improved the performance of their products to a certain level, then it would be _____.A. justified for them to cut the priceB. unnecessary for them to make any new changesC. difficult and costly to further better themD. insignificant for them to cut down the research costs61. In the case of cars, the author urges that we______A. cancel the speed limitB. further improve their performanceC. improve their durabilityD. change models every two years 62 The author's criticism is probably based on the fact that______A. we have been persuaded to live an extravagant life todayB. many products we buy turn out to be substandard or inferiorC. inflation is becoming a big problem in the world todayD. people are wasting their money on trivial technological progressPassage ThreeRecent studies on the male-female wage gap predict that even though entry-level salaries for males and females in the same occupation are nearly equal because women's market skills have improved vastly, the chances of the overall gap closing in the foreseeable future are minimal. This is due to several factors that are likely to change very slowly, if at all. An important reason is that women are concentrated in occupation- service and clerical- that pay less than traditional male jobs .It is possible that more women than men in their twenties are hesitant to commit themselves to a year-round lifetime career or job for many reasons. There is lingering attitude on both the part of women and their employers that women are not cut out for certain jobs. Not only does this attitude channel women into lower-paying work, but it also serves to keep them from top management positions.Another significant factor in the widening wage gap between men and women after entering the work force, even in comparable jobs, is that women often drop out at critical points in their careers to have a family. Women still have the primary responsibility for child rearing; even if they continue to work, they often forgo overtime and promotions that would conflict with home responsibilities. The ages of 25 to 35 have been shown repeatedly to be the period when working consistently and hard is vital to advancement and job security. These are precisely the years when women are likely to have children and begin to slide away from men in earning power. Consequently, a woman's income is more likely to be seen as secondary to her husband's .63. According to recent studies on the male-female wage gap _____.A. there is much hope of narrowing the male-female wage gap in the near futureB. working women will have many opportunities to hold high-paying jobs in the near futureC. women's pay will still stay at a level below that of men in the near futureD. salaries for males and females in the same , occupation will be equal in the nearfuture64. Women are kept from top management positions partly because they______A. decide to devote themselves to certain lifetime jobs in their twentiesB. are inclined to rank family second to workC. tend to have more quarrels with ,their employersD. still take an incorrect attitude towards themselves65.Which of the following is implied in the passage as a partial reason for women's concentration in certain occupations?A. Social division of laborB. Social prejudice against themC. Employment lawsD. Physiological weakness66. The word "forge" in Paragraph 2 could best be replaced by______A. give upB. drop outC. throw awayD. cut out67. It can be inferred from the second paragraph that______A. men's jobs are subject to changeB. women tend to be employed off and on at the same jobC. men's chances of promotion are minimalD. women used to be employed ail the year round68. Which of the following statements is NOT true?A. Women's market skills have improved greatly.B. child care is still chiefly women's work .C. Women are typically employed in clerical and service jobs.D. Domestic duties no longer conflict with women's jobs.Passage FourIt seems that the life of a television reporter is fantastically admired by many people. But this is only one side of the coin. First, he never goes deeply into any one subject-he may be expert at mastering a brief in a short time and "getting up" a subject, but a week later he is on to the next subject, and a week later still he is on to the subject after that. He seldom grasps with a full-scale investigation any one thing. He has to be able to forget what he was working on a few weeks before, otherwise his mind would become messed up.Second, a reporter does not have anything lasting to show for what he does-there is no shelf of books, no studio full of paintings. He pours his life into something which flickers in shadows across a screen and is gone forever. I have seen people in many television jobs turn at the end of watching one of their own programs and say something like: "Well, that's all those days / weeks / months of work. Travel and worry sunk without trace." As a way of life it comes to seem like blowing bubbles- entertaining to do, and the bubbles numerous and pretty to look at, and all different, but all disappearing into thin air.Third, the pace of the life is too fast. Not only is it destructive of one's private life; one does not even have time to give proper consideration to the things one is professionally concerned with not enough time to think, not enough time to read, not enough time to write one's commentary, prepare one's interviews and so on. When one disengages from it and allows one's perceptions, thinking, reading and the rest to proceed at their natural pace one gets an altogether unfamiliar sense of solidity and well--being.Fourth, the reporter is at the mercy of events. A revolution breaks out in Cuba so he is off here on the next plane. Somebody shoots President Reagan so he drops everything he is doing and flies to Washington. He is like a puppet pulled by strings -- the strings of the world's affairs. He is not motivated from within. He does not decide for himself what he would like to do , where he would like to go, what he would like to work on . He is activated from without, and his whole life becomes a kind of reflex action, a series of high-pressure responses to external stimuli. He has ceased to exist as an independent personality.69. A TV reporter never makes an in-depth study of a subject because______A. he usually gets one side of the pictureB. the subjects that he has to attend to often switch from one to anotherC. he does not know how to develop it to its full-scaleD. that is the life that suits him70. It is implied but not stated that many people______A. know nothing about the work of a TV reporterB. think the life of a TV reporter dull and boringC. have a biased opinion against the job of a TV reporterD. tend to underestimate the hard part of being a TV reporter71. TV reporting, according to this passage , is something______A. profitable for a person to take upB. interesting to do but quick to fade outC. causing a person to forget his previous workD. producing a lasting effect72. A TV reporter is in most need of______A. being a master of his timeB. proper consideration of his professionC. a comfortable life of his ownD. disengaging himself from work73. The activities of a TV reporter are largely geared to______A. his motivationB. his working styleC. current affairsD. reflex to pressure74. The title of this passage would best be given as______A. What a TV Reporter Can and Cannot AccomplishB. The Sorrows of TV ProfessionalsC. The Confession of a TV ReporterD. The Drawbacks in the Life of a TV ReporterPassage FiveThe urge to explore is innate in Man. Wherever his imagination wanders, Man seeks also to go. A large part of history is concerned with the exploration of the world in which we live. Time and again men have set out with amazing courage and resolution to probe into unknown regions and lands. They crossed the seas in flimsy boats, traversed continents, scaled mountains, fought their way through jungles and swamps, endure untold hardships -- all to explore, to see what had not yet been seen, to make known the unknown. Nor did Man confine his movements to the surface of land and sea. With kites balloons and aircraft he left the ground to range through the lower atmosphere. Now outer space receives his attention.The hard way to answer the question, why should Man bother about conquering space, is to attempt to list the specific practical benefits that will result. One knows, from past experience in other areas, that Man will surely see and discover new things in space, that will increase our store of scientific knowledge, and this new knowledge will find its way into valuable practical uses. What we learn about Man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be invaluable. The new techniques developed to carry out the exploration of space, and to keep men alive in space, will inevitably find their way into valuable practical uses in everyday living. The areas that will benefit are manifold. They include communications, generation of power, transportation and travel, food production, conservation of resources, navigation, human comfort and welfare, biology and medicine, materials, fuels and many others. But to state specifically just what the practical outcomes will be is virtually impossible.75. Exploration of the unknown______A. often results in Man's power of imaginationB. is not common throughout human historyC. is generally sought after by men with courage and strengthD. is deeply rooted in the instinct of Man76. Which of the following best sketches the process of Man's probe into the unknown world?A. Surface of the earth, the air and spaceB. Waters, mountains and forestsC. Waters, mountains and forestsD. Urge, imagination and courage77. The benefits of space exploration are basically something______A. well-specifiedB. hypotheticalC. practicalD. inevitable78. According to this passage, the value of exploring the outer space will ultimately lie in______A. its testimony Man's courage and resolutionB. the knowledge it may help us to gain about our earthC. the results it may bring about in the interests of ManD. Man's mastery of techniques to fly and stay alive in space79. From this passage we can conclude that Man should have confidence in exploring space because______A. we have directed our attention to the right object of studyB. we have accumulated experience from previous success to other fields.C. we have found the correct answer to the question of why Man should bother about conquering spaceD. we have already made it possible for people to benefit from his endeavor80. The idea express in this passage can be use in an argument ______A. in favor of criticism on space exploration.B. against spacing million of money on space argument.C. supported of paralleling man’s conquest with of space .D. to justify space exploration with its for reaching significant in life.PAPER TWOPART V TRANSLATION (40 MINUTES, 20 POINTS )Section A (20 minutes, l0 points)Directions: Put the following passage into Chinese. Write your Chinese version on Answer Sheet II.Many stories in the history of science show that chance plays a definite part in scientific discovery. However, a further analysis of these stories also reveals that chance alone is not sufficient for findings of primary importance. Scientific discovery also depends on how a scientist utilizes accidental opportunities. To ensure success, a scientist must, first of all, be able to react in a positive manner to unexpected and even apparently adverse results, taking them as stimulation for further investigation. Secondly, he must possess a superior power of observation to recognize the significance of those phenomena which often seem trivial and, therefore, may easily escape notice. This power of observation consists in a dual quality of' being sensitive to, and curious about, small accidental occurrences and of possessing a frame of reference capable of suggesting the true significance of those phenomena. Finally, he should be equipped with the capacity to plan and undertake careful and systematic experimentation.Section B (20 minutes, 10 points)Directions: Put the following passage into English.

本节课突出让学生在活动中了解、认识人民币，本节是本单元的第一节课，由于学生对人民币的认识已经有一定的生活经验，因此教材注意结合学生生活经验，创设了一个非常有趣的情境——买文具，让学生在购物活动中初步认识人民币，理解人民币的功能。
通过“认一认”、“猜一猜”等一系列活动让学生认识人民币，掌握元、角、分之间的关系。
又通过“小狗买文具”、“小猪逛超市”、“小兔存钱”等活动来了解人民币之间的兑换，以及培养学生解决简单问题的能力。
四、教学方法：上课之前，我用百度在网上搜索人民币的相关教学材料，找了一些教案和材料作参考，了解到教学的重点和难点，确定课堂教学形式和方法，然后根据本节课堂教学需要，利用百度搜索关于本节课的一些课件，课堂播放给学生看，引起学生兴趣。
五、教学目标：1.通过一系列活动，认识小面额人民币，理解元、角、分之间的进率和兑换。
2.以活动为载体，培养学生自主探索、合作交流的能力。
3.体会1元钱的价值，感悟数学知识与现实生活的密切联系。
4.养成爱护人民币、合理使用人民币的良好习惯。
重点：在活动中认识小面额人民币，理解元、角、分之间的换算关系。
难点：运用元、角、分之间的关系进行兑换，体会1元钱的价值。
六、教学过程：一、情境导入，激发兴趣：同学们，你们喜欢看动画片《喜羊羊与灰太狼》吗？这天，羊妈妈给了喜羊羊1元钱，喜羊羊非常高兴，决定到文具店买文具。
（课件）（板书：买文具，齐读课题。

思科路由器设置方法和常见配置命令
思科路由器设置方法和常见配置命令思科路由器设置方法和常见配置命令思科路由器怎么设置，是我们经常遇到的问题，下面店铺准备了关于思科路由器设置方法和常见配置命令，欢迎大家参考学习!一、基本设置方式一般来说，可以用5种方式来设置Cisco思科路由器：1.Console口接终端或运行终端仿真软件的微机;2.AUX口接MODEM，通过电话线与远方的终端或运行终端仿真软件的微机相连;3.通过Ethernet上的TFTP服务器;4.通过Ethernet上的TELNET程序;5.通过Ethernet上的SNMP网管工作站。
但Cisco思科路由器的第一次设置必须通过第一种方式进行,一般用超级终端通过com口进行控制。
此时终端的硬件设置如下: 波特率：9600数据位：8停止位：1奇偶校验: 无二、命令操作Cisco思科路由器所用的操作系统是IOS.共有以下几种状态：1、router>在router>提示符下，Cisco思科路由器处于用户命令状态，这时用户可以看Cisco思科路由器的连接状态，访问其它网络和主机，但不能看到和更改Cisco思科路由器的设置内容。
此时输入?并回车，可以查看到在此状态下可以用的命令。
(IOS允许你在任何时候用这种方式查看在某种状态下可以用的命令)。
在敲入enable并回车后，按照系统提示输入密码，(在新的Cisco思科路由器第一次进行调试的时候不需要输入密码，直接回车即可)进入#提示符，就可以对Cisco思科路由器进行各种操作了。
2、router#Cisco思科路由器进入特权命令状态router#后，不但可以执行所有的用户命令，还可以看到和更改Cisco思科路由器的设置内容。
此时就可以对Cisco思科路由器的名字、密码等进行设置。
3、router(config)#在router#提示符下键入configure terminal,出现提示符router(config)#，此时Cisco思科路由器处于全局设置状态，这时可以设置Cisco思科路由器的全局参数。

F41安装蓝牙模块)
现在支持蓝牙传输的手机和各种设备越来越多了，如果本本有内置蓝牙，对于各种设备间的数据交换就更加便利了。
也许有的本友会说买个USB的蓝牙适配器不就行了，还省钱。
但我们买本本是为了什么呢，是便携、简捷和更多功能的集成。
在ACER本友会里加装蓝牙的贴子一大堆，而我们联想本友会的加装蓝牙的贴子寥寥无见。
看到网友hfm2001已经成功安装了内置蓝牙，遂动起了为自己的本本加装蓝牙模块的念头。
希望借此带动联想天逸本友会内无内置蓝牙的本友自己动手安装蓝牙模块的兴趣。
一、蓝牙资料：1、联想天逸F40、F41与HP、ACER部分机型的蓝牙模块是一样的，都是BCM92045NMD蓝牙模块。
蓝牙模块背面蓝牙模块正面（此图已经用文字标出模块的1~8针脚）2、BCM92045NMD蓝牙模块的针脚定义联想天逸F40、F41蓝牙模块BCM92045NMD针脚定义图，此图是我拆机后根据连接线和接口画的，买不到联想原装蓝牙线的，可以根据此图动手加工一根线，只要线序按照下图排列即可。
BCM92045NMD蓝牙模块1~8针脚的定义3、联想天逸F40、F41蓝牙连接线接口都是8针，厚度1.25mm。
F41主板上的蓝牙接口图1 F41主板上的蓝牙接口图2蓝牙连接线图4、联想天逸F40、F41蓝牙模块安装位置是相同的。
安装在本本面板的左边，即下图中画红色圆圈处蓝牙模块安装在面板的背面的此处图1蓝牙模块安装在面板的背面的此处图2二、购买蓝牙模块蓝牙线的过程：4月6日，联系taobao店主昆山金友，他说手上的线测试了，不能用于联想天逸F41，只好另外想办法。
4月12日，联系网友aswind，因为F40和F41系列本本的蓝牙模块和蓝牙线是通用的，所以请他帮忙在联想阳光客服处代购原装联想蓝牙线。
4月17日，网友aswind跟我联系了，说在联想阳光客服订购的原装蓝牙线（单价30元，不含邮费）已经到货，就等aswind去取后寄给我。
4月19日，在taobao店主mlbalce处订购的BCM92045NMD蓝牙模块（单价68元，不含邮费）已经送到，我现在就等着aswind的线来安装蓝牙模块了。
