第一篇:英文作文汉语翻译

3.作文汉语译文

我叫付萍,我是一名19岁的大学生.我诚挚的延聘一名外国女大学生一同进行一次为期三周的旅游.

我的计划是下周启航,当暑假正式开始的时分,榜首站是昆明.这座城市以它的俊美和温文的气候而享誉国际。咱们将乘火车去哪里玩上两天。紧接着,咱们将前往井冈山,一个曾经的革新根据地(毛主席开始他的伟大事业的当地)。但它也有着他俊美的天然风光,然后咱们会坐船顺流而下前往上海。咱们能够赏识到国际第三大河的沿江俊美的风光。众所周知,上海是中国最繁忙和最兴隆的城市。咱们想见识一下他的昌盛,因而咱们将在上海停留半周。一句知名的中国谚语说过:“上有天堂,下有苏杭”。所以花上附迩来旅游一下这两个靠近上海的城市也是十分有必要的。悉数时辰加起来,咱们的旅游将继续三周。

我仅期望我的女伴能和一同我分管旅游的费用而且和我用很棒的英语扳话。而我将会是一个优秀的导游,已然我是旅游的首要导游。敬重的女士和先生们:

我在十月二号的北京青年日报上得知贵公司在招聘一个文秘的职位.我觉得这个职位我能够担任,我便写了这封求职央求信.

我从北京科技大学结业,而且获得了金融管理学士学位.在大学时辰我的首要课程包括微观经济学,商务礼仪,电子商务运用,我分外喜爱商务礼仪这门课,因为因为它能够很大程度上行进我的接人待物的才华.

结业后,我在惠普中国区商场部任部长助理一职,我的职责就是实施商场查看,写陈述,而且组织部分会议.我在那里学到了的这些宝贵的履历将担任贵公司如今空缺的职位.

我英语四级和六级均以高分经过.我的英语口语也很流利,足能够组织英语商洽.因为那是我在惠普公司的平常作业.我的大多数商场陈述均用英文记载,我的上一任老板更说的是一口地道的英伦腔.

我很谢谢你们对我的诚挚照看,我期望提前得到你们面试我的机缘.

此致:王鹏 迩来几年,大学入学的学生人数稳定增长。这关于一些中学生来说,是个好的音讯。这样他们将会有好的机缘承受高档教学。

你很简略发现添加高档教学人数的利益,一方面,传闻大学结业生和他们的家长很着急,你能够还会记住在曾经被高档校园所供认似乎是一件很难的作业,在那时学生为了预备入学考试承受了很大的压力,除此之外添加高档教学人数能够给说到咱们国家人的受教学水平作出贡献,咱们在现代的经济社会斗争,就像是建立国际化的形象相同,为了实现目标,咱们需求更多受过超卓教学的市民,此外, 添加高档教学人数能够供给更多具有专业常识的学生,这样,可推进社会打开

另一方面,咱们不能否定,大学的不断扩大带来一些疑问,起先,越来越多的学生升入大学,宿舍和食堂变的越来越拥堵。跟着学生的人数不断添加,教职工短少和设备的缺点的疑问暴露的越来越严厉。对教员的担负越来越重,咱们置疑这也将给教学质量带来很消沉的影响,乃至更糟的是不断扩大的学生人数将激化求职竞赛,简直一切的学生升入大学,想要找一份好的作业,怎么能让他们在四年学习之后面对着一个竞赛愈加严厉的境况时满怀绝望和居丧呢。

判定是不是大概煽动这种趋势并不是一件简略的事。以我来说,给予更多的学生更高档的教学,是值得煽动的。但一个大学学衔并不只是意味着十分好的作业和将来的一纸证书。为了组织一个有期望的作业,咱们需求更多的咱们在大学里所学不到的才华。

六,去知道校园以外的事

跟着咱们这个社会的敏捷打开,校园就像是一个象牙塔。学生有必要去触摸校园以外的国际,这样他们才华在结业后更快地习气这个社会群体。

简直一切的学生都是经过电视 收听广播节目和看报纸来知道状况。他们中有些人也会在他们的业余时辰做兼职作业:家庭教员,在快餐店作业或是其他的。一切的这些豆科仪让学生触摸这个社会。

如今暑假(寒假)快要来了,我预备为自个找一份在办公室打字的作业。我学了好几年的打字,我以为我能够作好它。这是个极好的机缘让我知道这个谁会,去知道怎么和伙随同处和去知道怎么把自个的常识运用到操练中去。下个学期开始,我照常试着去做一些像这样的杂活。不论薪酬怎么,我想最重要的事是我能够实在的去知道社会。

七,远离网吧运动

据报导,滁州某中学迩来建议一个名为“远离网吧”的活动。1000多名学生签名并严厉的许诺他们将不会花一分钟在网吧。关于快要降临的暑假,这个活动关于安康发育有分外重要的含义。

网络给咱们带来很大便当,在查找资料,娱乐节目和联络他人,还有它有利于一些商人,分外是开网吧的人。可是网吧都是根据规律运营的,可是它也有供给不安康的程序包括暴力和黄色内容。关于中学生有欠好的倾向的影响,他们很难认出哪个网吧是好的,哪个个是坏的,他们脱离网吧是个正确的挑选,除此之外,脱离网吧也能够对学生的身体安康有利益。消沉地坐在电脑屏幕前太多时辰,他们的视力和身体都会感到痛苦。

显尔易见地,“远离网吧”的活动是有价值建议的,它应得到其他校园的建议

大学吞并,在校园表里都是一个热门话题,而且受到了许多公共注重,现已成为了一个有争议的疑问,咱们的观念趋向于很大的不相同

一些人附和这个观念,以为这是开始缔造国际大学的重要时刻,他们谈论那些经过吞并能给他们带来利益宽和决不便当的当地,复旦大学和上海榜首医学院就是个比方,后者的力气在医学范畴是抵偿前者,前者的功用在自个的范畴以高科技抵偿后者。他们也指出大学吞并能够添加中国大学在国际上的竞赛实力。

在不担任的争议中,有些人把它当作一个草率的挑选,当有一些能够呈现的难题,他们对之保持沉默。举个比方,当彼此位于很远的时分,大学间常堕入运营难题。

从我的观念看,大学吞并是利大于弊的,但大学间有必要思考吞并带来的风险作用,九

就像要了解一只小鱼在大池子里与一只大鱼在小池子里的差异,所以这是关于一个小角色在大公司与一个有才华者在小公司作业的疑问。

从前者看,你能够从作为国际出名公司如贝尔.通用的成员上得出深化和满意的定论,你会有机缘学习管理者的履历和得知规范的作业方法。

从后者看,你有更大的职责,而且你的挑选能够带来深化的效果。一般你要脱离帮助和教训单独说出各式各样的履历和期望来做许多事。

对我来说,我更喜爱在小公司作业,我升官的期望事仰仗尽能够长的竭力作业来使自个优秀。说实话,我甘愿在我的小池子里做一个出名和重要的人。

网络们日子中已不在格外,从某种程度上说,它已成为咱们平常日子中的一部分,在网上咱们能够做许多作业,比方查找报导和五湖四海的兄弟谈天,可是迩来另一种对人有很大帮助的网络活动现已变的很盛行,那就是网络教学.为什么网络教学在很短时辰内会变得很受等候呢?在许多缘由中得知,其间极为重要的一点是网络教学能够很快行进水平,让咱们参加在很远当地上的课的期望成为能够,另一个潜在的缘由是社会和技术水平的疾速打开.当今,现代科学技术的飞速打开,要追上年代的打开,咱们有必要抱着急切的心境和剧烈的期望去学习,可是,因为现代社会的快节奏,许多人太忙以致于不能有满意的时辰在校园学习,网络教学便成为他们的帮助者.依我看,我赏识这种新的教学方法,这实际上是对传统教学方法的一种完善,这还能够给不相同的教授供给许多活络和多方面的方法去学习,整体上说,关于网络教学,咱们既能够据守咱们的作业岗位,一同学习而且承受最新的常识.十一

一个好的教员联络能够有用的推进学生学习水平的大幅度行进,教员要有耐性而且要知道和煽动学生而不是强逼和对学生运用暴力,这种师生联络能够使学习变得高兴和诙谐,学生也将竭力的学习.可是,一个不谐和的师生联络,很难抵达教学的意图学生将没有太大的勇气去学习.向他学习也回带着过失和否定的心境.因而教学也也会成为一项很难的作业是恶性循环.我以为师生联络大概被注重,一个好的联络使教员的作业变的很值得,坏的联络影响学生的行进乃至往后的日子.(一)An Introduction to the Library Write a passage about 150 words to introduce a library you know.The library is an important part of our college.Making a proper use of it will certainly help you a lot in your study.On the first floor, there is the periodical room.To the right of the doors there are shelves with current periodicals.The new issues are so arranged that the students can see the front cover of the current magazines.Daily newspapers are also in this area.There are eight comfortable chairs and two low tables nearby for students to read newspapers and periodicals.The card catalog is on the left of the periodical room.The cards are in alphabetical order according to the title of a book or periodical, the author, and the subject, which makes it easy for the students to find things they want.On the second floor, there is another study area.All books are on shelves in order.The shelves are called stacks.This library has open stacks so that the students can look for books themselves.If you want to borrow or return books, the librarians at the desk will be at your service.If you want to photocopy some articles, you can go to the leftmost room on the second floor.The photocopy machines there will do it for you.(二)Directions: For this part, you are allowed 30 minutes to write a composition entitled Asking for Leave of Absence.You should write at least 120 words according to the following guidelines: Your name and role: Sam, a sophomore in English Class Two Your foreign teacher’s name: Ms.Riddle Incident: you cannot come to her class for some reason Task: Write her a note, asking for leave of absence

Wang Peng

No.3120, Zhongshan Road Xu hui District Shanghai, 200076 September, 28th, 2003 Dear Sir or Madam, I learned from Beijing Youth Daily Oct.2 that your company is offering a position for a secretary, and it’s a great pleasure for me to write to explore the possibility of seeking the job.I graduated two years ago from Beijing University of Technology, and obtained a bachelor’s degree in the field of business management.During my stay in the university my major courses included macro-economics, business communication skills, marketing and computer applications.I was especially fond of the communication skills which enabled me to deal with people and things around well.I passed both CET-4 and CET-6 with high marks.My spoken English is also fluent enough to organize meetings in English, which was actually my routine work in HP.Most of my market reports were presented in English, as my former boss is a native English speaker.I enclose herein my resume and some relevant documents as required.And if you need my further information on me, I also refer you to Mr.Johnson, my ex-colleague, who is available at 021-66668888.I appreciate your sincere consideration of me, and am looking forward to an early interview with you.Sincerely yours,Wang Peng

(五)Increased College Enrollment 1. 这些年大学入学率逐年上升 2. 大学扩招的长处及潜在疑问 3. 我对大学扩招的观念

In recent years, there is a steady increase in college enrollment.To many high-school students it’s definitely good news, for they would have better chance of receiving higher education.You don’t have to look very far to find out the advantages of the increased college enrollment.For one thing, it lessens the worries of both high-school graduates and their parents.You may not forget the old days when the college admission seemed to be the hardest thing to get.In those days, students preparing for college entrance examination were under great pressure.Besides, increased college enrollment can contribute to raise the educational level of our nation.We are now striving for modernizing our economy as well as building a good international status.To achieve that, we must have more well-educated citizens.What’s more, increased college enrollment can provide more students with specialized knowledge, thus serving our development in a positive way.It’s not an easy task to tell whether the tendency should be encouraged.As to me, it’s laudable to grant more students higher education.But a college degree is by no means a guarantee for a better job or future.To cast a promising career, we need a lot more abilities which we can not learn from college.(六)Getting to Know the World outside the Campus 1.大学生知道社会的必要性

2.知道社会的方法(群众前语、社会效能等)3.我计划怎么做

With the rapid development of our society, the campus is no longer an “Ivory Tower”.Students must get in touch with the world outside the campus so that they can adapt themselves t society more quickly when they graduate.Almost all students keep themselves informed by TV, radio broadcasts and newspapers.Some of them even take up part-time jobs in their spare time: working as tutors, serving in some fast-food restaurants and others.All these have kept students in touch with society.(七)Directions: For this part, you are allowed 30 minutes to write a composition entitled Away from Net-bars Campaign.You should write at least 150 words according to the following guidelines(given in Chinese): 1.新闻媒体宣告,滁州某中学1000多名学生签名,严厉许诺“远离网吧”; 2.剖析“远离网吧”运动的缘由; 3.做出对此的谈论。

It has been reported that a middle school in Chuzhou City has recently launched a campaign named “Away from Net-bars”.More than a thousand students have signed for their solemn promise that they will not spend a single minute in the net-bars.With the nearing of the summer vacation, this campaign is especially meaningful for the healthy development of the minors.Obviously, the “Away from Net-bars Campaign” is an activity that is worth advocating and it merits other schools’ reference.(八)University Merger 1.大学吞并是其时的热门话题; 2.咱们对大学吞并持有不相同的心境; 3.我的观念。

University merger, a hot topic both on and off campus, has received much public attention.As a controversial issue, people’s attitude towards it differs greatly.In spite of these arguments, there are those who see it as a hasty decision, which has some potential problems.They claim, for instance, located far away from each other, the universities involved in a merger are usually faced with the tough problem of management.In my opinion, university merger has more advantages than disadvantages, but universities should take into account the potential dangers resulting from merging.(九)To Be a Small Fish in a Big Pond or a Big Fish in a Small Pond? 1.在大公司作业的特征; 2.在小公司作业的特征; 3.我的挑选。

(十)Online Education 1.其时网络教学构成热潮; 2.我以为这股热潮的缘由是…… 3.我对网络教学的评估。

Being online is no longer something strange in our life.To some degree, it has become part of our daily life.We can do a lot of things online, such as searching for information and communicating with friends far and near.But recently another helpful online activity has become very “in”.That is online education.Personally, I appreciate this new form of education.It’s indeed a helpful complement to the traditional educational means.It can provide different learners with more flexible and versatile ways of learning.Most of all, with online education, we can stick to our jobs and at the same time study and absorb the latest knowledge.(十一)The Teacher-Student Relationship 1.好的师生联络有益于学生的打开; 2.不良的师生联络有害于学生的打开; 3.我以为……

A good teacher-student relationship is able to effectively further the student to a higher level in study.The teacher with patience and understanding encourages the student instead of pushing or forcing him.The relationship of this sort makes learning so enjoyable and funny that the student would work hard willingly.As I see it, the relationship between a teacher and a student should be attached much importance to.A good relationship makes the teacher’s job worthwhile while a bad one ill-affects the student’s development, even to the rest of his life.

液压系统与气压系统

液压传动和气压传动称为流体传动,是根据17世纪帕斯卡提出的液体静压力传动原理而发展起来的一门新兴技术,1795年英国约瑟夫•布拉曼(Joseph Braman,1749-1814),在伦敦用水作为工作介质,以水压机的形式将其应用于工业上,诞生了世界上第一台水压机。1905年将工作介质水改为油,又进一步得到改善。

第一次世界大战(1914-1918)后液压传动广泛应用,特别是1920年以后,发展更为迅速。液压元件大约在 19 世纪末 20 世纪初的20年间,才开始进入正规的工业生产阶段。1925 年维克斯(F.Vikers)发明了压力平衡式叶片泵,为近代液压元件工业或液压传动的逐步建立奠定了基础。20 世纪初康斯坦丁•尼斯克(G•Constantimsco)对能量波动传递所进行的理论及实际研究;1910年对液力传动(液力联轴节、液力变矩器等)方面的贡献,使这两方面领域得到了发展。

第二次世界大战(1941-1945)期间,在美国机床中有30%应用了液压传动。应该指出,日本液压传动的发展较欧美等国家晚了近20 多年。在 1955 年前后 , 日本迅速发展液压传动,1956 年成立了“液压工业会”。近20~30 年间,日本液压传动发展之快,居世界领先地位。

液压传动有许多突出的优点,因此它的应用非常广泛,如一般工业用的塑料加工机械、压力机械、机床等;行走机械中的工程机械、建筑机械、农业机械、汽车等;钢铁工业用的冶金机械、提升装置、轧辊调整装置等;土木水利工程用的防洪闸门及堤坝装置、河床升降装置、桥梁操纵机构等;发电厂涡轮机调速装置、核发电厂等等;船舶用的甲板起重机械(绞车)、船头门、舱壁阀、船尾推进器等;特殊技术用的巨型天线控制装置、测量浮标、升降旋转舞台等;军事工业用的火炮操纵装置、船舶减摇装置、飞行器仿真、飞机起落架的收放装置和方向舵控制装置等

传递动力只有三种方法:电传动、机械传动、液压传动。实际上,许多设备将这三种方式组合起来形成一个更有效的系统。知道三种方式的各自突出优点是确定哪种方法是最好的传递方式的重要因素。例如:液压比机械能够更有效的进行远距离传递。然而,液压传动没有电传动的距离远。

液压动力系统一般比较关注调节流量和控制压力,这样的系统一般包括:

1.泵是一种将原动力转化成液体压力的机构。

2.阀是用来控制泵的输出流量的方向、产生压力的大小和流量的大小。能量的大小是通过控制流量和压力的大小所决定的。3.执行机构是在需要的地方将液压能转换成可用的机械能的机构。

4.传递介质是液体,其提供刚性传动和控制,被密封在阀处提供润滑作用以及起冷却系统的作用。

5.连接件,是用来连接各种系统组件,传递压力油液并使油液返回油箱。

6.油箱和冷却器,是分别用来保证油液质量和冷却油液的。7.气动系统需要通过油雾器向从调压阀出来的气体中撒入润滑油。这是为了防止气动系统配合件间的磨损。

液压系统是用于工业应用,如冲压机、钢铁厂、制造业、农业机械、矿业、航空、空间技术、深海勘探、交通、海洋技术、海上天然气和石油勘探。简言之,每个人的生活都要受益于液压技术。放电加工又叫做电镀或者电火花加工,是基于火花放电侵蚀金属的原理。我们知道当两根带电的导线接触时会产生电弧,如果我们仔细观察连接两根导线的金属时会注意到一小部分金属已经被侵蚀掉留下了一个小坑。

基本的电火花加工系统是由一个连接到直流电源的形状工具和工件及其两者之间的电介质组成,这是一种最广泛使用的加工过程,尤其是刻锻操作——当工具与工件件的电位差足够高时通过电流的瞬间放电,从工件表面移除非常少得金属。

机械控制包括凸轮和调速。尽管他们已经被用于比较复杂的机器,但为了更加经济,今天它们被用于简单和固定周期控制。一些自动化机器,如螺杆机,仍然使用凸轮基础控制。机械控制机构很难制造但不容易磨损。

但气动控制在某些应用上仍非常受欢迎,它是由压缩空气、气动阀和转换开关组成的简单逻辑控制系统。虽然容易反应迟缓,但由于是由标准件构筑逻辑,因此比机械控制容易建立。气动控制系统容易受磨损。

像机械控制系统一样,机电控制系统使用开关、继电器、时间计数器等等来构建逻辑,它更加快和灵活。控制器采用机电控制被称为中继设备。

流体动力是自动化系统的肌肉,是因为一下四个方面: 1.简单而精确的控制。通过简单的杠杆原理,流体动力系统可以轻松的启动、停止、加速或者减速,并且定位动力可以提供任何的动力需要而使定位偏差精确到1/10000英寸。2.成倍的动力。液压系统可以简单而有效的将一盎司的力转换成百吨的输出力。3.恒定的力或转矩。只有液压系统可以不管速度怎么变化保持提供恒或力转矩,这可以适应不论是输出的速度或转速是几英寸每小时、几百英寸每秒还是几转每小时、几千转每秒。4.简单、安全、经济,一般情况下液压系统可以比机械或者电力系统用更少的零件实现同样的功能。

因为它们的简单维护和操作而使安全度和可靠性实现最大化。例如,新的转向机构的产生使得其他车辆的电力系统显得陈旧,转向单元有在一个整体上得许多手动操作的方向控制阀和进油调压阀组成。运输、海洋技术、海上天然气和石油勘探等各个领域都离不开液压。它提供了简单的系统。另外,很小的输入扭矩去控制最难得应用。在有限的空间里需要一个小得转向机构是非常必要的而且能够减少操作者的疲劳。液压系统的另外一个好处就是可以立即进行可逆运行。自动的过载保护和无级变速控制。液压系统可以有比任何一直电源都高的动力。尽管液压有这么多的优势但也不能代替所有的动力传递。气动系统

气动系统是依靠压缩气体来进行传递和控制的。气压系统通常用空气(不用其他气体)作为流体介质,因为空气是安全、成本低而又随处可得的流体,在系统部件中产生电弧有可能点燃泄漏物的场合下(使用空气作为介质)尤其安全。在气动系统中,压缩机是用于压缩和供应充足的空气,压缩机通常有活塞式、叶片式或螺钉式。一般的压缩机是靠压缩体积来增加空气压力。气动系统通常使用一个大型集中的空气压缩机,并认为它是无限大的。空气源类似于电力系统只需将插头插入就可以获得电力。这样压缩空气管道可以从一个气源引出接到整个工厂的不同地方。压缩空气可以通过过滤器将空气中的污染物去除,这些污染物将会损坏气动系统的配合部件,例如阀和气缸。之后压缩空气经过一个减压阀将压缩空气的压力降到特定应用所需的值。由于空气没有好的润滑效果(包含20%的氧气),气动系统需要一个油雾器将润滑油注射到从调压器输出来的压缩气体中。这样可以防止有配合移动的气动部件的损坏。大气中的空气含有不同程度的水分,这些水分会洗掉润滑剂从而导致过度磨损和腐蚀,因此,在某些应用中需要空气干燥剂来消除这些不良的水分。因为气动系统排气直接进入大气,将会带来噪音,因此消声器安装在排气阀口和执行件处以减少噪声,并且使操纵人员避免噪声和灰尘颗粒的污染。气动系统将代替液压系统的可能性原因有以下几个因素;

液体的惯性比气体的大,因此在加速和减速、启动和制动时存在潜在的问题。

由于牛顿定律(F=m×a),将油液加速所需的力比将气体加速到同样值所需要的力要大很多倍,这导致更大的摩擦压力和功率损失。而且液压系统采用的油液介质与气体不同,它需要设置特制的储存油箱和无泄漏回油系统。液压系统 工程液压回路 泵就是用来提供压力油的也可以说是提供动力。阀是用来控制油的流量和控制提供需要的压力。每一个液压动力系统用一个或者多个泵提供液压油。从液压动力系统出来的液压油完成工作。压力油用来推动活塞杆在气缸中运动或者使液压马达的轴转动。泵的作用就是液压动力系统中将油液加压以完成工作。一些动力系统使用低压100pi来完成工作。当需要大功率输出时可以达到10000pi或者更多,所以我们发现现在的一些液压动力系统是由至少一个泵来加压油液的。泵的种类

三种类型的泵应用在泵的动力系统中。(1)回转泵(2)往复泵(3)离心泵。在泵的特性匹配中,使泵的最好的特点完成特殊的工作是一种趋势,例如,一个离心泵可以和一根柱塞泵串联一起提供压力油。控制阀

压力控制阀用来保证不同回路所需的压力值,压力控制阀利用将高压区的油转移到低压区从而保证高压区的压力。阀可以分为安全阀、减压阀、平衡阀、顺序阀和卸荷阀。
