如果不会粤语和英语，在澳门应聘酒店客房服务员的差事，严重地影响你跟入住客人的交流，自然会影响你对入住客人的服务质量。所以你只能做一些吃苦受累的体力活(如洗衣房等)。如果你是女孩子，退休老师建议你还是在沿海城市的酒店找一份工作吧！祝你好运。

客房服务员可以有别的称呼。根据查询相关公开信息显示：一些高档酒店中，客房服务员通常被称为客房管家，因为他们不仅负责打扫客房，还要提供更加全面的服务，如整理客人的衣物、洗涤客人的私人物品等。客房服务员是酒店中负责打扫和维护客房的员工，为客人提供全方位服务。

咖啡英文单词是coffee。咖啡（英文名：coffee），指采用经过烘焙过程的咖啡豆所制作冲泡的饮料，口感方面以酸、甜、苦、咸四种滋味为主，气味则根据咖啡豆品种、冲泡方式等呈现多种变化。作为人类社会流行范围最为广泛的饮料之一，与可可、茶被称为世界三大饮料。咖啡起源于非洲埃塞俄比亚，通常被分为阿里比卡种与罗布斯塔种。在成熟后需经历采摘、处理、烘焙等程序，根据制作方式产生多种饮品形式，如浓缩咖啡、拉花咖啡、单品咖啡、速溶咖啡、瓶装饮品等。咖啡由于其所含分子或存在致癌物质等因素而存在对人体有害的争议，然而咖啡多样的风味及其造就的咖啡文化、经济效应增产则带来了深远影响。咖啡的英语句子合集：1：There was a smell of coffee pervading the atmosphere.空气里弥漫着咖啡的香味。2：I"d like some coffee with a laced brandy.我想喝一点加少量白兰地的咖啡。3：I have coffee after dinner,as is my usual practice.我饭后喝咖啡，这是我的习惯。4：Here,have some coffee on me.来，我请你喝咖啡。5：He used to have a cup of coffee preparatory to his work.在工作之前，他总要喝上一杯咖啡。6：Which blend of coffee would you like?你要哪一种混合咖啡?7：Have another coffee on me.再来一杯咖啡，我请客。8：I love the delightful odour of freshly roasted coffee beans.我喜欢刚烘烤好的咖啡豆的清香气味。9：Fresh coffee is superior to instant coffee.现煮的咖啡比速溶咖啡好。10：Call room service and ask for some coffee.叫客房服务员送些咖啡来。

我去也是因为实习，老师让写实习论文，实在没会写，是我一个同学介绍在汇博在线上写的，信誉和质量还不错，你去问问他们，地址你在百度搜汇博在线就可以找到了。

你的打扮完全OK。2，专业知识你也没有问题，也有经验，应该问题不大。可以说是相对较好的了。我们这有很多都是小酒店来的。有的人也不是专业学校毕业的。3，就我的经验而言，他会问你一些个人情况，对酒店的理解，对服务业的理解，你对未来的规划打算，对该酒店看法等等。如果你说你英语好的话他会要求你用英语做自我介绍，但是通常情况下你需要知道客房内部设施物品的英文名字，还有几句简单的会话。这样就算是基本过关。4，酒店业人士变化比较大，他们比较害怕那种干两天就走的人。人事部经理那关比较好过，到了部门经理他一般会给你说工作很辛苦之类的话来试探你。你一定要说你能吃苦愿意从基层慢慢做起，能坚持下来。说话语气坚定一点。说实话其实酒店都很缺人，因为真的很辛苦。

一般都是培训完就上岗很少考证的当然，如果有客房服务证更好呵呵，我就有客房服务证

客房服务员是为宾馆或酒店的客房提供清洁及为住户提供生活帮助的服务人员。1.客房服务员应该是整个酒店里面最累的岗位，正常清洁一间客房的标准时间为30分钟，客房服务员每天清洁房间基数为10-12间，超过基数后每多清洁一间客房，按房态不同，提成也不一样。2.客房服务员下班前还得对工作间、布草间、消毒间进行整理，撤换出来的脏布草还得交付给洗衣房并登记数量，还有可能需要接收送洗回来的布草。还要写好交接班，并交还清洁卡，对讲机，并与中班交班。3.客房服务员也有男性的，并且有很多非常优秀的男性客房服务员。客房打扫是个力气活，男性力量大。只是，大家潜意识里都觉得打扫卫生家务是女性的活，愿意去从事这项工作的男性比较少而已。培训要求1、培训期限全日制职业学校教育，根据其培养目标和教学计划确定。晋级培训期限：初级不少于70标准学时；中级不少于80标准学时；高级不少于100标准学时。2、培训教师培训初级客房服务员的教师应具有本职业中级以上职业资格证书；培训中、高级客房服务员的教师应具有本职业高级职业资格证书或本专业中级以上专业技术职务任职资格，同时具有2年以上的培训教学经验。3、培训场地设备教室、服务台（配备电脑）、标准客房（或模拟标准客房）以及相关教具及设备。

一．前言(一)实习单位介绍1、实习单位：xxxxxx酒店xxxxxx酒店 —— 位于xx省xx市xx路，是按照x星级标准建造、xxxxxx式酒店。酒店背倚郁郁葱葱的xxxx，面朝xxxxxx。整体占地面积达 20 万平方米，建筑面积达 7. 8 万平方米 ，富丽典雅的欧陆式建筑风格，使宾客感受到西方古典文化独特的神秘雅致。此外，酒店还特别引进了国外主题式酒店的独特意念，创造出超凡的品味。xxx酒店由xxx集团斥资约xx亿元重金兴建，充分发挥“商务、度假、会议”的功能优势，在完善xxxx楼盘配套的同时从容开展商务和度假活动，推动xxx“给你一个五星级的家”的品牌品质的持续提升。2、实习部门：前厅礼宾部前厅部包括：接待处、礼宾部、总机、商务中心、订房部共五个分部门，酒店实行部门经理负责制，由前厅经理统筹安排，各分部主任或分部经理管理本部门事务，与其他部门密切配合，合作完成工作。礼宾部作为宾客迎来送往在最重要的部门之一，分设行李生和酒店代表两个部分，由礼宾经理总体负责，下设行李生领班（3人）和行李生（11人），酒店代表主管（1人）资深酒店代表（1人）和酒店代表（4人）。（二）实习职位介绍酒店代表是代表酒店在机场、火车站等出入境口岸迎送客人，及时向客人推销酒店和宣传酒店的形象，影响着客人对酒店的印象。酒店代表的主要任务是提供快捷妥当的服务，将客人接回酒店入住或送机送车，作为最早和最后接触客人的酒店员工，把握每一个机会不失时机地为酒店作宣传，争取更多的客源，负责保护客人的行李和人身安全，为客人提供酒店内外设施、环境咨询，为客人提供尊贵的礼宾服务。二 实习内容（一）酒店代表日常工作1、利用xxx酒店的“千里马酒店管理系统”查阅每天的“接机、接车服务报表”，详细登记当天的服务需求情况并按中文、英文、日文用A3纸打印成2/6页“SIGNBOARD”，在纸后面写上接机（车）日期、航班号、始发地、预计到达时间、人数、是否收费等信息。2、查询航班信息，确定时间和到达情况，报告主管进行车辆和人员安排。3、带齐所需物品出车，在机场（车站）最后确认航班到达时间和出口，提前到达出口处准备迎接客人。4、接到客人，确认其身份，核对无误之后带其乘车回酒店，安排登记和入住事宜。5、在礼宾部柜台为客人提供咨询、寄存等礼宾服务。（二）酒店代表的VIP/大客户接待工作1、与销售部相关人员核对当天预计抵达的VIP人数和姓名。2、准备相关物品，检查是否有遗漏。3、向有关部门了解客人信息，准备接待事宜。4、视客人要求和酒店安排，与订房部、销售部、接待处等部门共同安排客人到站活动和酒店活动。（三）酒店代表交易会期间的工作1、打印“接机接车报表”和“预抵报表”，核对接机接车报表和SIGNBOARD。2、带齐所需物品，与机场（车站）工作人员联系协商接站事宜。3、安排客人休息区域，为客人提供酒店信息咨询等服务。4、与酒店密切联系，负责机场与酒店之间的穿梭巴士的调度工作。--------------------------------------------------------------------------------三．实习主要收获和体会（一）实习收获1、服务意识的提高对于酒店等服务行业来讲,服务质量无疑是企业的核心竞争力之一,是企业的生命线.高水平的服务质量不仅能够为顾客留下深刻的印象,为其再次光临打下基础.而且能够使顾客倍感尊荣,为企业树立良好的品牌和形象. 通过酒店组织的培训和平时部门的强化练习，锻炼了我的服务意识，养成了面对客人泛出微笑的好习惯；学会了用标准的礼仪礼貌待客；明白了学好外语的重要性。2、服务水平的提高经过了三个多月的酒店实习，使我们对酒店的基本业务和操作有了一定的了解，礼貌是一个人综合素质的集中反映，酒店更加如此，要敢于开口向人问好，在向人问好的过程中还要做到三到：口到，眼到，神到，一项都不能少。对于客人的要求，要尽全力去满足，尽管有些不是我们职责范围的事情，也要尽力帮其转达；尽管有些要求不合理的不能办到，都要用委婉的语气拒绝，帮他寻求其他解决方法。印象最深的是为酒店的日本客人（大多数是来自酒店大客户——本田公司的）服务，他们通常是不太会说英语的，所以，我们要从他们的动作和片言只句中猜到3/6页他想要做什么并快速帮他办好。例如：当客人用蹩脚的英语说到AIRPORT时，就要猜到他是想到机场，要我们安排免费的送机服务。接下来就要为他们提供乘车预约表并接受他的信息再交由主管排车了……3、英语水平的提高在五星级的涉外饭店中，英语的实际应用能力包括听、说、写的能力是特别重要的。在接触来自世界各国的客人的过程中，英语作为国际通用语言发挥了它的重要性，没有它，我和客人就没法沟通，更提不上为他（她）服务。交易会期间，客人们从世界各地赶过来，就要我们用英语为他们介绍，接受他们对会馆、天气、地理、购物等信息的咨询，及时向客人推销xx和宣传酒店的形象。（二）实习体会1、实习不是体验生活实习占用了我们大学里的最后一个暑假的时间，但是这和以往打的暑期工不同，在工作过程中，我们不是单纯地出卖自己的劳动力去换取报酬，而是当自己是酒店的一员，和各部门同事密切合作维护酒店形象和创造最大的利益。实习过程中，我们不会因为还是本科在读生而受到特别的礼遇，和其他心员工一样，从酒店基本知识和本职工作开始了解，偶尔做错事，也不会有人偏袒。2、实习是一个接触社会的过程通过这次实习，我比较全面地了解了酒店的组织架构和经营业务，接触了形形色色的客人，同时还结识了很多很好的同事和朋友，他们让我更深刻地了解了社会，他们拓宽了我的视野，也教会了我如何去适应社会融入社会。3、实习期与xxx酒店的关系作为酒店的一员，穿上了制服，就要处处维护xxx酒店的权益，要把自己和酒店紧密联系起来，要熟悉酒店的信息，要另自己的一言一行都要代表酒店的利益，时刻为酒店做宣传，提高酒店和自己的形象。4、实习与就业实习过程中，让我提前接触了社会，认识到了当今的就业形势，并为自己不久后的就业计划做了一次提前策划。通过这次实习，我发现了自己与酒店的契合点，为我的就业方向做了一个指引。另外，xxx酒店的人才培养制度为我们提供了大量的学习机会，为我们提供了就业机会。实习实际上就是一次就业的演练。四 实习想法和建议（一）实习想法初步接触了酒店业和xxx酒店，发现人员流动量大是整个行业的问题。酒店业的从业者素质参差不齐，从中学文化到研究生甚至更高文化的都有；同时，员工的年龄跨度很大，小的刚满18岁，但是有的部门普通员工已经年过半百了。年龄和文化程度的差异，决定了酒店在效率上的差异，如：客房服务员的英语水平普遍不高，在客人需要某些客房服务时，他们往往听不懂其要求而要前台或者服务中心同事的帮助，将电话转来转去耽误了时间，还会造成客人的不满。

将一个模拟电压信号与一个基准电压相比较。对两个或多个数据项进行比较，以确定它们是否相等，或确定它们之间的大小关系及排列顺序称为比较。 能够实现这种比较功能的电路或装置称为比较器。比较器的两路输入为模拟信号，输出则为二进制信号0或1，当输入电压的差值增大或减小且正负符号不变时，其输出保持恒定。可以将比较器当作一个1位模/数转换器（ADC）。运算放大器在不加负反馈时从原理上讲可以用作比较器，但由于运算放大器的开环增益非常高，它只能处理输入差分电压非常小的信号。而且，一般情况下，运算放大器的延迟时间较长，无法满足实际需求。

生石灰是氧化钙的俗称，能与水反应生成氢氧化钙，可作食品包装袋内的干燥剂，反应的化学方程式为：CaO+H 2 O═Ca（OH） 2 ．生成的氢氧化钙能与空气中的二氧化碳反应生成碳酸钙和水，用过一段时间后，干燥剂中的物质最多有氧化钙、氢氧化钙、碳酸钙三种．有些食品包装袋内的干燥剂是铁粉，铁粉与水、氧气充分接触时容易生锈，生成的铁锈的主要成分是氧化铁，氧化铁呈红色．铁和水、氧气共同作用时生成铁锈，所以与生石灰干燥剂比较，铁粉除了做干燥剂外，还可做吸氧剂，比生石灰更能延长食品保质期．故答案为：CaO+H 2 O═Ca（OH） 2 ；三；红；铁粉除了做干燥剂外，还可做吸氧剂．

Thomas Edison lost his first job.For the next five years he went around the country from job to job.At last Edison went to New York.He had little money.He could not buy enough food to eat.He had no place to sleep. For many days Edison looked for work.He was hungry.At last he found work fixing machines.He could fix the old machines.He also made new ones.The headman liked Edisons new machines.He was going to give Edison ＄40,000 for them.Edison would now have money to do what he wanted. Thomas Edison was then 23.He used the money to build a shop in New Jersey.He had many people working for him.But he worked more than any of them.He rested very little.Soon he was making more than 40 new things at one time. In 1876 Alexander Graham Bell made a telephone.But it could carry voices only a little way. Edison wanted to make a better telephone.He soon made one.It could carry voices a long way. 爱迪生于1847年2月11日诞生于美国中西部的俄亥俄州的米兰小市镇。父亲是荷兰人的后裔，母亲曾当过小学教师，是苏格兰人的后裔。爱迪生7岁时，父亲经营屋瓦生意亏本，将全家搬到密歇根州休伦北郊的格拉蒂奥特堡定居下来。搬到这里不久，爱迪生就患了猩红热，病了很长时间，人们认为这种疾病是造成他耳聋的原因。爱迪生8岁上学，但仅仅读了三个月的书，就被老师斥为“低能儿”而撵出校门。从此以后，他的母亲是他的“家庭教师”。由于母亲的良好的教育方法，使得他对读书发生了浓厚的兴趣。“他不仅博览群书，而且一目十行，过目成诵”。8岁时，他读了英国文艺复兴时期最重要的剧作家莎士比亚、狄更斯的著作和许多重要的历史书籍，到9岁时，他能迅速读懂难度较大的书，如帕克的《自然与实验哲学》。10岁时酷爱化学。11岁那年，他实验了他的第一份电报。为了赚钱购买化学药品和设备，他开始了工作。12岁的时候，他获得列车上售报的工作，辗转于休伦港和密歇根州的底特律之间。他一边卖报，一边兼做水果、蔬菜生意，只要有空他就到图书馆看书。他买了一架旧印刷机，开始出版自己的周刊——《先驱报》，第一期周刊就是在列车上印刷的。他用所挣得的钱在行李车上建立了一个化学实验室。不幸有一次化学药品着火，他连同他的设备全被扔出车外。另外有一次，当爱迪生正力图登上一列货运列车时，一个列车员抓住他的两只耳朵助他上车。这一行动导致了爱迪生成为终身聋子。 1862年8月，爱迪生以大无畏的英雄气魄救出了一个在火车轨道上即将遇难的男孩。孩子的父亲对此感恩戴德，但由于无钱可以酬报，愿意教他电报技术。从此，爱迪生便和这个神秘的电的新世界发生了关系，踏上了科学的征途。

　　1、可以将比较器当作一个1位模/数转换器(ADC)。运算放大器在不加负反馈时从原理上讲可以用作比较器,但由于运算放大器的开环增益非常高,它只能处理输入差分电压非常小的信号。而且,一般情况下,运算放大器的延迟时间较长,无法满足实际需求。 　　比较器经过调节可以提供极小的时间延迟,但其频响特性会受到一定限制。为避免输出振荡,许多比较器还带有内部滞回电路。比较器的阈值是固定的,有的只有一个阈值,有的具有两个阈值。 　　2、通俗来讲电压比较器的基本功能是能对两个输入电压的大小进行比较，判断出其中哪一个比较大。比较的结果用输出电压的高和低来表示。

Thomas Alva Edison lit up the world with his invention of the electric light. Without him, the world might still be a dark place. However, the electric light was not his only invention. He also invented the phonograph, the motion picture camera, and over 1,200 other things. About every two weeks he created something new.Thomas A. Edison was born in Milan, Ohio, on February 11, 1847. His family moved to Port Huron, Michigan, when he was seven years old. Surprisingly, he attended school for only two months. His mother, a former teacher, taught him a few things, but Thomas was mostly self-educated. His natural curiosity led him to start experimenting at a young age with electrical and mechanical things at home.When he was 12 years old, he got his first job. He became a newsboy on a train that ran between Port Huron and Detroit. He set up a laboratory in a baggage care of the train so that he could continue his experiments in his spare time. Unfortunately, his first work experience did not end well. Thomas was fired when he accidentally set fire to the floor of the baggage car.Thomas then worked for five years as a telegraph operator, but he continued to spend much of his time on the job conducting experiments. He got his first patent in 1868 for a vote recorder run by electricity. However, the vote recorder was not a success. In 1870, he sold another invention, a stock-ticker, for $40,000. A stock-ticker is a machine that automatically prints stock prices on a tape. He was then able to build his first shop in Newark, New Jersey.Thomas Edison was totally deaf in one ear and hard of hearing in the other, but thought of his deafness as a blessing in many ways. It kept conversations short, so that he could have more time for work. He called himself a "two-shift man" because he worked 16 out of every 24 hours. Sometimes he worked so intensely that his wife had to remind him to sleep and eat.Thomas Edison died at the age of 84 on October 18, 1931, at his estate in West Orange, New Jersey. He left numerous inventions that improved the quality of life all over the world.爱迪生 (1847-1931) 　　19世纪被誉为科学的世纪，也是以科学的技术化和社会化为突出特征的世纪。科学在这个世纪开始成为社会生活的一个重要组成部分。风起云涌的伟大创新转变成为技术科学的巨大威力。这个世纪的一些科技巨擘继续活跃于20世纪。托马斯·阿尔沃·爱迪生（Thomas Alva Edison）,就是其中之一。美国《生活》周刊不久前评出的过去1000年的100位最有影响力人物中，爱迪生名列第一。　　爱迪生出身低微、生活贫困，他的“学历”是一生只上过3个月的小学，老师因为总被他古怪的问题问得张口结舌，竟然当他母亲的面说他是个傻瓜、将来不会有什么出息。母亲一气之下让他退学，由她亲自教育。这时，爱迪生的天资得以充分地展露。在母亲指导下，他阅读了大量的书籍，并在家中自己建了一个小实验室。为筹措实验室的必要开支，他只得外出打工，当报童、办报纸。最后用积攒的钱在火车的行李车厢建了个小实验室，继续作化学实验研究。后来，化学药品起火，几乎把这个车厢烧掉。暴怒的行李员把爱迪生的实验设备都扔下车去，还打了他几记耳光,据说爱迪生因此终生致聋。　　爱迪生是美利坚民族崇尚的那种传奇般的人物——虽未受过良好的学校教育，但凭个人奋斗和非凡才智获得巨大成功。他自学成才，以坚韧不拔的毅力、罕有的热情和精力从千万次的失败中站了起来，克服了数不清的困难，成为美国发明家、企业家。他早年曾制定双工式和四工式电报系统，发明自动电报帮电机。1877～1879年发明留声机；实验并改进了电灯（白炽灯）和电话。以后又制定了照明系统，并为实现集中供电进行了许多工作。他提出并采用直流三线系统。制成当时容量最大的发电机，并于1882年利用该机建成了第一座大型发电厂。在同时期，作了铁道电气化的试验。1883年发现“爱迪生效应”，即热电子发射现象。在电影技术、矿业、建筑、化工等方面也有不少著名的发明，仅从1869年到1901年，就取得了1328项发明专利。在他的一生中，平均每15天就有一项新发明，他因此而被誉为“发明大王”。　　爱迪生献身科学、淡泊名利。在研制电灯时，记者对他说：“如果你真能造出电灯来取代煤气灯，那你一定会赚大钱。”爱迪生回答说：“一个人如果仅仅为积攒金钱而工作，他就很难得到一点别的东西——甚至连金钱也得不到！”他一直被称作现代电影之父，可是在电影界人士为他77岁寿辰举行的盛大宴会上，他说：“对于电影的发展，我只是在技术上出了点力，其他的都是别人的功劳。”　　爱迪生胸襟开阔、善处逆境。针对自己的耳聋不便，他说：“走在百老汇的人群中，我可以像幽居森林深处的人那样平静。耳聋从来就是我的福气，它使我免去了许多干扰和精神痛苦。”1914年某天晚上，爱迪生的电影实验室突遭火灾，损失巨大。爱迪生安慰伤心之极的妻子说：“不要紧，别看我已67岁了，可我并不老。　　从明天早晨起，一切都将重新开始，我相信没有一个人会老得不能重新开始工作的。”第二天，爱迪生不但开始动工建造新车间，而且又开始发明一种新的灯——一种帮助消防队员在黑暗中前进的便携式探照灯。火灾对爱迪生就像是一支小小的插曲。　　爱迪生造福大众、不畏艰辛。为寻找灯丝，他试验了数千种材料；为试制一种新的蓄电池，他失败了八千次。因此，爱迪生常常说：“天才是百分之一的灵感加上百分之九十九的勤奋。”他在80岁时，仍然保持着发明家的精神，坚张地进行着发明创造活动。1927年，他成立了爱迪生植物研究公司，投入一个崭新的研究领域，寻觅化工新材料。81岁高龄的爱迪生成功地从野草中提炼出橡胶，受到人们极高的评价。　　1931年10月18日清晨3时24分，爱迪生带着宽慰的微笑，闭目辞世，享年84岁。临终时他坦然地说：“我为人类的幸福，已经尽力了；没有什么可遗憾的了。”　　举行葬礼的那天，全美国熄灭电灯一分钟，以示哀悼。这是人们表达对爱迪生无限怀念之情的最隆重的方式，也是人们献给这位伟大发明家的一曲无言的赞歌。

LED等如何实现技能及原理解答如下：节能和原理可合并为一个问题，即原理就是实现节能的方式：由于LED的是利用固体半导体芯片作为发光材料，而在日常生活中所用到的灯泡是利用金属作出发光材料，因此所发出的能量有所不同，据有关统计，一个红色LED发光达到某个亮度时所需消耗的能量是15瓦，而传统的灯泡要达到同等量度则要消耗高达150瓦的能量；另外据科学家们测定，LED通电发光时，有10%的电能可以转化成光能，而白炽灯泡的转化效率只有7-8%，由此可见，要达到同等的照明效果，LED灯比白炽灯节能是显而易见的了。

因为生石灰——氧化钙(CaO)可以与空气中的水分(H2O)发生化学反应：CaO + H2O == Ca(OH)2 (沉淀），生石灰与水反应生成了熟石灰自然吸收了空气中的水分。生石灰拓展：石灰干燥剂的主要成分为氧化钙（CaO），其吸水能力是通过化学反应来实现的，因此吸水具有不可逆性。不管外界环境湿度高低，干燥剂都能保持大于自重35%的吸湿能力，更适合于低温度保存，具有极好的干燥吸湿效果，而且价格较低。可广泛用于食品、服装、茶叶、皮革、制鞋、电器等行业。通常制法为将主要成分为碳酸钙的天然岩石，在高温下煅烧，即可分解生成二氧化碳以及氧化钙。凡是以碳酸钙为主要成分的天然岩石，如石灰岩、白垩、白云质石灰岩等，都可用来生产石灰。在沿海地区有用贝壳作原料，经烧制成壳灰，作生石灰用。湿气的管控是与产品的良率是息息相关的。以食品而言，在适当的温度和湿度下，食物中的细菌和霉菌便会以惊人的速度繁殖，使食物腐坏，造成受潮及色变。

Therefore, I believe, I have the ability to do a good job in this profession, I hope the garden can give me the leadership of a chance to prove themselves. 　　I am a university student about to graduate, I will be graduating in July 2010 early childhood professional, according to my own situation, I think I also engaged in early childhood education has a certain advantage. First of all, the social status quo, the present-day universal child care teachers are women, which indirectly affect the development of some physical and mental health of boys, which are specific to the lack of male masculinity and motherhood tend to. Therefore, to develop male sex education teachers to promote the father is a very important task. In addition, early childhood I have a great interest. In school, I studied psychology, pedagogy and the results are very prominent, and I have a two-level Certificate in Putonghua. I think these are also the industry on the basis of early childhood education. In terms of ideology, of modern early childhood education methods I have some idea of their own. Today"s society are the traditional sense of the kindergarten, and its essence is placed on the ban, the lack of true character of education. Although the basis of existing conditions and differences in standard of living allows us to face this reality, but the desire to education their children by parents or characteristics account for a large proportion, it features pre-school education is a very promising industry. I say education is not simply the characteristics of bilingual education and Mongolia are now popular education. I envisaged the development of children"s education is based on nature, according to the interest of the child"s specific teaching methods courses. If the leadership of the need to park, I will detail my thoughts. 　　Of course, I have engaged in early childhood education for the industry there will be many difficulties, there are a lot of my own deficiencies, I understand the characteristics of education is only my own understanding of a number of shallow, and I do not have any job experience, not digital. These I will be able to view clear, I believe I have a strong will, for their own inadequacies, I will, through the tireless efforts and training at work, learning to make up for in order to improve their own ability to self-improve. For the reform of traditional education, even though I am not going to play a key role, but I also hope to contribute to a strength of its own, because I怀揣the cause of the ideals of early childhood education. 　　Finally, I sincerely hope that the garden can give me the leadership of an ideal opportunity to achieve, I believe I will eventually do the profession relies on luck rather than strength. Similarly, for the garden I would make my biggest contribution. 　　Sincerely, 　　Salute ;

Thomas Edison was born on February 11, 1847 and died on October 18, 1931. He was an inventor and businessman who developed many important devices. "The Wizard of Menlo Park" was one of the first inventors to apply the principles of mass production to the process of invention. In 1880 Edison founded the journal Science, which in 1900 became the journal of the American Association for the Advancement of Science. Edison is considered one of the most prolific inventors, holding a record 1,093 patents in his name. Most of these inventions were not completely original but improvements of earlier patents, and were actually works of his numerous employees. Edison was frequently criticized for not sharing the credit. Nevertheless, Edison received patents worldwide, including the United States, United Kingdom, France, and Germany. Edison started the Motion Picture Patents Company, which was a conglomerate of nine major film studios.
