geoffrey loves. he prepared the speech carefully and went to the wedding with jenny. he had included a large number of funny stories in the speech and, of course, it was a great success. as soon as he had finished, jenny told him she wanted to go home. geoffrey was a little disappointed by this but he did as his daughter asked. on the way home, he asked jenny if she had enjoyed the speech. to his surprise, she said she hadnt. geoffrey asked her why this was so and she told him that she did not like to see so many people laughing at him!lesson64 the channel tunnel 海峡隧道in l858, a french engineer, aime thome de gamond, arrived in england with a plan for a twenty-one mile tunnel across the english channel. he said that it would be possible to build a platform in the centre of the channel. this platform would serve as a port and a railway station. the tunnel would be well-ventilated if tall chimneys were built above sea-level. in 1860, a better plan was put forward by an englishman, william low. he suggested that a double railway tunnel should be built. this would solve the problem of ventilation, for if a train entered this tunnel, it would draw in fresh air behind it. forty-two years later a tunnel was actually begun. if, at the time, the british had not feared invasion, it would have been completed. recently, there has again been great interest in the idea of a channel tunnel. if it is built, it will connect britain to europe for the first time in history.lesson65 jumbo versus the police 小象对警察last christmas, the circus owner, jimmy gates, decided to take some presents to a childrens hospital. dressed up as father christmas and accompanied by a guard of honour of six pretty girls, he set off down the main street of the city riding a baby elephant called jumbo. he, should have known that the police would never allow this sort of thing. a policeman approached jimmy and told him he ought to have gone along a side-street as jumbo was holding up the traffic. though jimmy agreed to go at once, jumbo refused to move. fifteen policemen had to push very hard to get him off the main street. the police had a difficult time, but they were most amused. jumbo must weigh a few tons, said a policeman afterwards, so it was fortunate that we didnt have to carry him. of course, we should arrest him, but as he has a good record, we shall let him off this time.lesson66 sweet as honey! 像蜜一样甜！the hatheld puffin is a modern aero-plane, but its designer, mr john wimpenny, is finding it difficult to get it off the ground. the reason for this is that this plane is also a bicycle. its pilot has to pedal hard to get it into the air. after mr wimpenny had the plane built, it was tested thoroughly. in 1961, it was the first man-powered aircraft to fly half a mile. while being flown by a champion amateur cyclist in 1963, the plane crashed on an airfield. since then, mr wimpenny has had it rebuilt. he has had the length of the wings increased so that they now measure 93 feet-almost as long as those of a dakota. many people have shown interest in this new and unusual sport. but though air cyclists may learn how to fly over short distances, and may, eventually, even get across the english channel, it is doubtful whether they will ever cycle across the atlantic.lesson67 volcanoes 火山haroun tazieff the polish scientist, has spent his life-time studying active volcanoes and deep caves in all parts of the world. in 1948, he went to lake kivu in the congo to observe a new volcano which he later named kituro. tazieff was able to set up his camp very close to the volcano while it was erupting violently. though he managed to take a number of brilliant photographs, he could not stay near the volcano for very long. he noticed that a river of liquid rock was coming towards him. it threatened to surround him completely, but tazieff managed to escape just in time. he waited until the volcano became quiet and he was able to return two days later. this time, he managed to climb into the mouth of kituro so that he could take photographs and measure temperatures. tazieff has often risked his life in this way. he has been able to tell us more about active volcanoes than any man alive. lesson68 persistent 纠缠不休i crossed the street to avoid meeting him, but he saw me and came running towards me. it was no use pretending that i had not seen him, so i waved to him. i never enjoy meeting bert dykes. he never has anything to do. no matter how busy you are, he always insists on coming with you. i had to think of a way of preventing him from following me around all morning.hullo, bert, i said. fancy meeting you here !hullo, elizabeth, bert answered. i was just wondering how to spend the morning-until i saw you. youre not busy doing anything, are you ? no, not at all, i answered. im going to. .would you mind my coming with you ? he asked, before i had finished speaking. not at all, i lied, but im going to the dentist. then ill come with you, he answered. theres always plenty to read in the waiting room !lesson69 but not murder! 并非谋杀！i was being tested for a driving licence for the third time. i had been asked to drive in heavy traffic and had done so successfully. after having been instructed to drive out of town, i began to acquire confidence. sure that i had passed, i was almost beginning to enjoy my test. the examiner must have been pleased with my performance, for he smiled and said, just one more thing, mr eames. let us suppose that a child suddenly crosses the road in front of you. as soon as i tap on the window, i want the car to be stopped immediately. i continued driving and after some time, the examiner tapped loudly. though the sound could be heard clearly, it took me a long time to react. i suddenly pressed the brake pedal hard and we were both thrown forward. the examiner looked at me sadly. mr eames, he said, in a mournful voice, you have just killed that child ! lesson70 red for danger 危险的红色during a bullfight, a drunk suddenly wandered into the middle of the ring. the crowd began to shout, but the drunk was unaware of the danger. the bull was busy with the matador at the time, but it suddenly caught sight of the drunk who was shouting rude remarks and waving a red cap. apparently sensitive to criticism, the bull forgot all about the matador and charged at the drunk. the crowd suddenly grew quiet. the drunk, however, seemed quite sure of himself. when the bull got close to him, he clumsily stepped aside to let it pass. the crowd broke into cheers and the drunk bowed. by this time, however, three men had come into the ring and they quickly dragged the drunk to safety. even the bull seemed to feel sorry for him, for it looked on sympathetically until the drunk was out of the way before once more turning its attention to the matador.lesson71 a famous clock 一个著名的大钟when you visit london, one of the first things you will see is big ben, the famous clock which can be heard all over the world on the b.b.c. if the houses of parliament had hot been burned down in 1834, the great clock would never have been erected. big ben takes its name from sir benjamin hall who was responsible for the making of the clock when the new houses of parliament were being built. it is not only of immense size, but is extremely accurate as well. officials from greenwich observatory have the clock checked twice a day. on the b.b.c. you can hear the clock when it is actually striking because microphones are connected to the clock tower. big ben has rarely gone wrong. once, however, it failed to give the correct time. a painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down ! lesson72 a car called bluebird “蓝鸟”汽车the great racing driver, sir malcolm campbell, was the first man to drive at over 300 miles per hour. he set up a new world record in september 1935 at bonneville salt flats, utah. bluebird, the car he was driving, had been specially built for him. it was over 30 feet in length and had a 2500 horse-power engine. although campbell reached a speed of over 304 miles per hour, he had great difficulty in controlling the car because a tyre burst during the first run. after his attempt, campbell was disappointed to learn that his average speed had been 299 miles per hour. however, a few days later, he was told that a mistake had been made. his average speed had been 301 miles per hour. since that time, racing drivers have reached speeds of over 400 miles an hour. following his fathers footsteps many years later, sir malcolms son, donald, also set up a world record. like his father, he was driving a car called bluebird.lesson73 the record-holder 纪录保持者little boys who play truant from school are unimaginative. a quiet days fishing, or eight hours in a cinema seeing the same film over and over again, is usually as far as they get. they have all been put to shame by a boy who, while playing truant, travelled 1600 miles. he hitch- hiked to dover and, towards evening, went into a boat to find somewhere to sleep. when he woke up next morning, he discovered that the boat had, in the meantime, travelled to calais. no one noticed the boy as he crept off. from there, he hitch-hiked to paris in a lorry. the driver gave him a few biscuits and a cup of coffee and left him just outside the city. the next car the boy stopped did not take him into the centre of paris as he hoped it would, but to perpignan on the french-spanish border. there he was picked up by a policeman and sent back to england by the local authorities. he has surely set up a record for the thousands of boys who dream of evading school.lesson74 out of the limelight 舞台之外an ancient bus stopped by a dry river bed and a party of famous actors and actresses got off. dressed in dark glasses and old clothes, they had taken special precautions so that no one should recognize them. but as they soon discovered, disguises can sometimes be too perfect.this is a wonderful place for a picnic, said gloria gleam. it couldnt be better, gloria, brinksley meers agreed. no newspaper men, no film fans! why dont we come more often ? meanwhile, two other actors, rockwall slinger and merlin greeves, had carried two large food baskets to a shady spot under some trees. when they had all made themselves comfortable, a stranger appeared. he looked very angry. now you gut out of here, all of you! he shouted: im sheriff here. do you see that notice ? it says no camping-in case you cant read ! look, sheriff, said rockwall, dont be too hard on us. im rockwall slinger and this is merlin greeves. oh, is it ? said the sheriff with a sneer. well, im brinksley meers, and my other name is gloria gleam. now you get out of here fast !lesson75 sos 呼救信号when a light passenger plane flew off course some time ago, it crashed in the mountains and its pilot was killed. the only passengers, a young woman and her two baby daughters, were unhurt. it was the middle of winter. snow lay thick on the ground. the woman knew that the nearest village was miles away. when it grew dark. she turned a suitcase into a bed and put the children inside it, covering them with all the clothes she could find. during the night, it got terribly cold. the woman kept as near as she could to the children and even tried to get into the case herself, but it was too small. early ,next morning she heard planes passing overhead and wondered how she could send a signal. then she had an idea. she stamped out the letters sos in the snow. fortunately, a pilot saw the signal and sent a message by radio to the nearest town. it was not long before a helicopter arrived on the scene to rescue the survivors of the plane crash.lesson76 april fools day 愚人节to end our special news bulletin, said the voice of the television announcer, we are taking you to the macaroni fields of calabria. macaroni has been grown in this area for over six hundred years. two of the leading growers, giuseppe moldova and ricardo brabante, tell me that they have been expecting a splendid crop this year and harvesting has begun earlier than usual. here you can see two workers who, between them, have just finished cutting three cart-loads of golden brownmacaroni stalks. the whole village has been working day and night gathering and threshing this years crop before the september rains. on the right, you can see mrs brabante herself. she has been helping her husband for thirty years now. mrs brabante is talking to the manager of the local factory where the crop is processed. this last scene shows you what will happen at the end of the harvest : the famous calabrian macaroni-eating competition ! signor fratelli, the present champion, has won it every year since 1961. and that ends our special bulletin for today, thursday, april 1st. we are now returning you to the studio.lesson77 a successful operation 一例成功的手术the mummy of an egyptian woman who died in 800 b.c. has just had an operation. the mummy is that of shepenmut who was once a singer in the temple of thebes. as there were strange marks on the x-ray plates taken of the mummy, doctors have been trying to find out whether the woman died of a rare disease. the only way to do this was to operate. the operation, which lasted for over four hours, proved to be very difficult because of the hard resin which covered the skin. the doctors removed a section of the mummy and sent it to a laboratory. they also found something which the x-ray of the god duamutef. this god which has the head of a cow was normally placedinside a mummy. the doctors have not yet decided how the woman died. they feared that the mummy would fall to pieces when they cut it open, but fortunately this has not happened. the mummy successfully survived the operation. lesson78 the last one? 最后一枝吗？after reading an article entitled cigarette smoking and your health i lit a cigarette to calm my nerves. i smoked with concentration and pleasure as i was sure that this would be my last cigarette. for a whole week i did not smoke at all and during this time, my wife suffered terribly. i had all the usual symptoms of someone giving up smoking: a bad temper and an enormous appetite. my friends kept on offering me cigarettes and cigars. they made no effort to hide their amusement whenever i produced a packet of sweets from my pocket. after seven days of this i went to a party. everybody around me was smoking and i felt extremely uncomfortable. when my old friend brian urged me to accept a cigarette, it was more than i could bear. i took one guiltily, lit it and 华智计算机管理信息系统（hzmis）可行性研究报告文档编号 hzmis001 版 本 号 v1.0 文档名称：管理信息系统可行性研究报告 项目名称：面向传统制造业管理信息系统 目 录1 引言31.1 编写目的31.2 背景31.3 有关术语解析31.4 参考资料42 可行性研究的前提52.1 要求52.2 目标与规模72.3 条件、假定和限制82.4 进行可行性研究的方法92.5评价尺度93 对现有系统的分析93.1 处理流程和数据流程93.1.1 华智公司概况93.1.2 系统工作流程123.1.3 现有系统计算机应用描述123.2 工作负荷133.3 费用开支143.4人员143.5 设备153.6 局限性154 所建议的系统184.1 对所建议系统的说明184.1.1 系统结构方案描述184.1.2 hzmis系统组成204.2 处理流程和dfd214.2.1 系统层（顶层）dfd214.2.2功能层dfd214.3 改进之处224.4 影响234.5 技术条件方面的可行性235 可选择的其它系统方案275.1 b/s方式275.2 c/s方式286 投资和效益分析316.1 支出316.1.1硬件设备投资316.1.2软件开支316.1.3 系统运行费用326.2 收益326.3 投资收益比336.4 投资回收周期336.5 敏感性分析337社会因素方面的可行性347.1 法律方面可行性347.2 使用方面可行性348 结论351 引言1.1 编写目的 本可行性研究报告是对公司现有系统现状、现有业务流程、系统开发的基本需求的初步调查，对建议的候选系统及其它可选系统进行比较，分析候选系统的可行性。对公司信息管理系统的可行性研究最根本的任务是对公司信息管理系统开发行动方针提出建议，并为项目开发制定初步计划。编写本可行性研究报告的目的是分析本公司及其它中小型企业现有管理系统的特点，分析企业的经营主线，分析公司部门业务流程及基本需求，根据基本需求提供候选系统及其他各种系统方案，并从经济上、社会条件、开发技术及运行环境方面分析候选系统的可行性，通过和其它系统方案进行分析比较，论证所选定方案是否可行。1.2 背景l 拟开发软件系统的名称：在本公司内部使用时系统名：华智管理信息系统（hzmis）。转向市场时暂定名为：面向中小企业的管理信息系统。l hzmis任务提出者：华南信息产业集团华智微控制分公司。l hzmis任务开发者：华南信息产业集团华智微控制分公司设计部软件组。l hzmis的用户：华南信息产业集团华智微控制分公司。l 软件接口：hzmis是在公司局域网上运行的公司信息管理系统，它连通公司的每个业务处理部门，各功能模块之间应提供无缝的接口。1.3 有关术语解析l mis（manage information system）：管理信息系统。l hzmis（uazhimanage information system）：华智管理信息系统。l c/s（client/server）:客户机/服务器，指一种常用的两层mis结构模式。l b/s（browser/server）:浏览器/服务器，是一种基于web浏览器和服务器的mis结构模式。l dfd（data flow diagram）:数据流图，一种描述系统信息流动和处理的结构化分析图形工具。1.4 参考资料l 计算机软件开发规范gb8566-88北京：中国标准出版社，1989l 计算机软件产品开发文件编制指南gb8567-88北京：中国标准出版社1989l 管理信息系统设计与实施清华大学出版社 199992 可行性研究的前提2.1 要求a.通过对公司系统内部各部门现况和基本需求的初步调查，经综合分析，hzmis系统应具备解决以下问题功能：l 仓库的出入货管理、备料管理、发料及产品回仓管理l 采购组的采购资料、购销合同、进退货及分供方（供应商）资料管理l 设备组的设备借出、归还、维修记录管理l 市场部的购销合同、客户资料及竟争对手资料管理l 生产部的生产控制（投入产出率）管理、生产员工劳动价值和工资计算、生产量和消耗品（包括工具）年度核算、工艺文件的管理l 质管部的质量管理控制l 财务部门的应收帐和应付帐管理、产品成本结算l 设计部门的 a.各种设计程序标准和要求查阅 b.各种元器件资料查询 c.项目的管理 d.目标计划管理，工作日志管理 e.技术文件的归档，查阅 f.标准模块、器件的生成与查阅调用 g.信息交流（各部门的交接文档管理） h问题的反映（包括：一般和紧急）l 综合部人员招聘管理、员工档案管理、员工培训管理、月度考核管理、考勤管理l 档案室的文档资料管理l 公司领导管理和决策b.性能：l hzmis系统要求能运行于一般计算机网络操作系统(如unix、windowsnt、netware等)。 l 系统界面采取目前最流行的windows操作界面，要求界面统一，操作简便，提供足够的在线系统帮助。l 系统i/o数据信息流程清晰、计算处理要准确、处理速度要迅速、数据表（单据）格式要标准、统一，而且表格格式能根据用户需要由用户灵活定义（提供excel接口）。l 系统要具有数据备份、数据恢复功能，能确保在系统崩溃时能尽快修复，减少损失。c.系统主要的输出报告，文件或数据：生产实时报表部门报告/文件数据/名称用途产生频度分发对象接口生产部投入产出量报表生产控制/核对按日产生生产办/主管生产统计表生产控制按月产生生产主管年度生产量、消耗量、损耗量报告汇报生产半年或年主管经理员工月工资表财务工资结算按月份财务部门现有的工资统计系统市场部销售统计报表汇报销售按年或月财务部/经理发出产品和货款回收月报表汇报销售按年或月财务部客户信誉统计表市场分析按年或月市场部主管物资部仓存报表汇报仓存/存根随机物资部现有系统（visual foxpro）数据转换欠料单制定采购计划随机采购人员出/入仓报告统计/核对工作按月、年物资部/财务采购统计报告统计/核对工作按月、年物资部/财务分供方信誉统计表采购分析按月、年物资部设备统计报告（包括借出归还）统计/核对工作随机物资部质管部检验样品不良率，批不格率统计表（可按分供方或材料名统计）采购分析，分供方信誉统计，汇报随机，不同时间段质管部/采购部现有系统（excel）数据转换质管部制程工序不良率统计表质量控制，汇报随机质管部/生产部现有系统（excel）数据转换客户返修板的不良信息统计质量控制，汇报随机质管部/设计部/生产部财务部应收账/应付账报告统计/核对工作随机财务部现有财务软件标准接口成本统计表成本控制随机
