基础综合英语_1-5单元课后翻译

作文翻译 Unit 1 李明是学化学的，性格开朗幽默，颇有魅力，但英语成绩不佳，每次只能勉强及格。老师警告他，英语不好会阻碍他拿奖学金，并亮出了自己的王牌：如果李明不努力，就让他考试不过关。老师还告诉他，学习英语不能只为了文凭，否则他即使大学毕业，也还是个半文盲。李明虽然保持镇定，但他明白，他的学业生涯正在攸关之际，必须安心下来埋头学习，坚持不懈。 Li Ming was a chemistry major, a charmer noted for his easygoing and humorous temperament. However, his English was so poor that he always barely got by. The teacher admonished him that his poor English would be an impediment to scholarship. What’s more, she showed her trump card: if Li Ming did not work hard. She would flunk him. He was also told that he should not learn English merely for the sake of his diploma. otherwise, even after graduation from university, he would still be semiliterate. Although Li Ming did not lose his composure, he was well aware that he had to settle down to work and follow through because his academic life was at stake. Unit2 我的朋友琳达接受过良好的教育，既美丽又端庄，三十好几依然没有人向她求婚。究其原因，她的事业心极强，整日扑在工作上，每天来往于住处和公司之间，根本没有时间和异性交往。一想到女儿这么大了还单身一人，她父母就焦虑不安。他们不知道该如何是好，甚至还去咨询一些社会学专家。但是事情在上个月出现了转机，公司的总部调琳达到培训部。在新的工作岗位上，琳达遇到了第一个触动她心弦的男人。从此，他们几乎每天约会，琳达意识到她会不顾一切地爱这个男人。决定嫁人的时候，她告诉了我这个好消息。虽然琳达的爱情让人想起电影中才会有的浪漫故事，我也担忧未来究竟会怎样，但我还是表达了我由衷的祝福，并爽快答应在婚礼那天做他们的伴娘和伴郎随从中的一员。 Linda, my good friend, has received good education and is both beautiful and elegant. She was not proposed to even when she was well over thirty. The reason is that she, as a career –oriented woman, is devoted to her work. Navigating between home and the company, she had hardly any time to socialize with people of the opposite sex. Her parents were gripped by anxiety at the thought of their daughter still remaining single at such an age. They did not know what to do and even consulted with some sociologists. But the situation began to change last month, when the headquarters of the company transferred Linda to the training department. On the new post, Linda met a man who tugged on her heartstrings for the first time. Ever since then, they dated virtually on a daily basis, and Linda realized that she would love the man beyond all reason. When she decided to take the matrimonial plunge, she informed me. Though Linda’s love is reminiscent of the romance that we see only in movies and I don’t know what the future will hold for her, I give her my heart-felt wishes and agree readily to be a member of the entourage of bridesmaids and groomsmen. Unit 3 食品供应商缺乏诚信已经成为当今社会的一大问题。部分企业欺骗公众，故意散布假消息，颂扬食品添加剂是食品工业的伟大成就，并声称适量的添加剂对健康有益无害。部分有良知的科学家对食品添加剂的含量和毒性展开了深入的病理学研究。研究结果表明，部分常见的食品添加剂经长期，可能会对健康产生危害，这被认为是食品安全研究方面极为重要的

Unit 1 原子钟电子或电子计时装置是由原子或分子的震荡控制的。一个计时装置必须包含或者连到一些均匀震荡的的仪器上来控制指针的移动的频率或者数字改变的频率。机械钟或者手表利用震荡平衡轮，钟摆和音叉。更高的精度或许利用原子或分子震荡，因为这种震荡频率如此高，不肯能用他们做控制时钟的直接手段.。然而，这种钟被一种高速平稳输出可以自动增加而且可以与原子系统的比较的晶体振荡器控制。这种震荡器的错误会自动改正。时间通常是由数字原子时钟或者其他的复杂的读数设备显示的。第一个原子时钟，发明与1948年，利用氨分子的振动。一对这样的时钟之间的误差，也就是说，在指定的时间如果两者统一瞬间启动然后比较,区别通常是三千年差一秒。在1955年，第一个铯束时钟（一种利用铯原子发射精密频率的微波光谱线作为参考的设备），在英国的特丁顿国家物理实验所投放操作。美国的标准是nist f-1，他是在1999年进入服务的并且在两千万年里不会快或者慢一秒。一个喷泉原子钟，NIST F-1原子钟包含由高3英尺的垂直管的内部结构.他用激光冷却铯原子，在空气中用激光摇匀形成铯原子团。特别像一个摇匀的网球。形成喷泉效果。这允许原子比以前的任何时钟都要观察的远。许多世界国家的标准实验室保存着原子钟，用这些时钟平均产生叫TAI的标准来维持时间。高精度的时间信号是来源于这些标准实验室通过短波无线广播站或者人造卫星向全世界传播的。这种信号被用来跟踪太空飞行器，电子导航系统和地壳的瞬间的研究等事情。这些精确的时钟使利用实验证明了一个很大的预言-爱因斯坦的相对论成为可能。原子钟的原型是用氢原子或者铍原子这样的原子可以几千年仍可以很准确。比如：美国家标准与技术研究院的研究人员已经证明过渡在一个基于能源困汞离子（汞原子丢失了一个电子）的时钟潜在着比目前时钟精确度高达1000倍。 Unit 2 制动（刹车）系统制动（刹车）踏板或者用手杆来激活（启动）刹车（制动），对于低功率的机器或者车，操作人员通常可以提供足够的力通过一个简单的机械运动把刹车踏板或者操作杆联系到刹车的部分上。然而，大多数情况下，这种力可以通过一种精心制作的系统来增加。空气制动系统空气制动系统是一种早期的系统用来增加制动力，也可以叫做空气制动，它是由美国乔治西屋的制造商发明的并与1868年第一次使用在乘客火车上。现在他被广泛应用在铁路火车上。它的基本原理是利用压缩运动空气使油箱的活塞安放在车轮上的闸块式制动器。动作同时作用在火车车厢的轮子上。通过连轴器连接的车厢之间通过用结实的管子传递空气。与此同时，通过工程师控制他释放在所有的单独的闸块式制动器部位。在制动管损坏，泄露或者是刹车部位损坏，它有自动提供所有闸块式刹车设置。空气制动系统也被应用在地铁，有轨电车，公共汽车和卡车。

大学英语综合教程2课后翻译

全新版大学英语综合教程2课后翻译 UNIT 1 我认为总结一下英语学习的经验是值得一试的。这里，我想谈谈三个相关的问题。首先，大量阅读应被视作学习过程中的重点，因为我们是通过阅读获取最大量语言输入(language input)的。其次，尽可能多背一些好文章也十分重要。一方面，死记硬背(rote learning)确实无甚裨益，但另一方面，在真正理解基础上的熟记肯定对我们有好处。大脑中存储了大量很好的文章，我们在用英语表达自己思想的时候，就会觉得容易多了。最后，我们应该把所学到的东西用到实践中去，这是至关重要的。通过多读、多写、多听、多说，我们就能完成提高英语水平的任务。 I consider it worthwhile trying to summarize our experience in learning English.Here I would like to make three relevant points. First,wide reading should be taken as a priority in the learning progress,because it is through reading that we get the most language input.Next,learning by heart as many well-written essays as possible is also very important.On the one hand,rote learning/learning by rote is indeed of little help,but on the other hand,memorization/learning by heart with a good understanding will certainly be of benefit /do good to us.With an enormous store of excellent essays in our heads,we will find it much easier to express us in English.Finally,it's critical that we should put what we have learned into practice.By doing more reading,writing,listening and speaking,we will be able to the task of perfecting our English. UNIT 2 自从他加盟以来，乔治从早忙到晚。他总是乐呵呵的，一直全身心地扑在工作上。由于表现出色，他被提升为执行总裁（CEO=CHIEF EXECUTIVE OFFICER）.从那以后，他尽力和工人打成一片，从不盛气凌人。另外，他制定了一些奖励制度，鼓励工人们努力工作。他相信忠诚和勤劳会大大促使公司获得成功。人们都说他是位出色的执行总裁。 George was on the run since the moment he came aboard.He was always cheerful and devoted himself heart and soul to his work.Because of his excellent performance he was promoted to CEO.From then on he tried hard to blend in with other workers and never threw his weight around.He also laid down/introduced a reward system to encourage the workers to work hard.He believed that loyalty and hard work would greatly contribute to the success of the company.By all accounts he was an outstanding chief executive officer. UNIT 3 约翰逊先生的儿子乔治爱在晚上听重金属(heavey metal)音乐，响声干扰了社区其他居民的睡眠。后来，疲惫不堪的邻居们失去了耐心，决定直接干预。他们打电话给约翰逊先生，坦率地把想法告诉了他。约翰逊先生感到很尴尬，便去训斥儿子：“你这是怎么了？你该懂得不能为了自己的兴趣而妨碍(disturb)别人。”结果乔治拿唱片跟同学换了电脑游戏软件(software)。总的来说，这件事解决得很圆满。 George,the son of Mr.Johnson,liked listening to heavy metal music in the evenings,and the noise interrupt ed the sleep of other residents in the community.Eventually the exhaust ed neighbours lost their patience and decided on direct interference.They called Mr.Johnson to tell him in a frank manner what they were thinking.Embarrass ed,Mr.Johnson scolded his son:"What has come over you?You should know better than to disturb others for the sake of your own interest."As a result George traded his records for computer games software from his classmates.Overall,the whole thing has worked out quite satisfactorily. UNIT 4 也许你羡慕我，因为我可以借助计算机在家里工作。我也这么想，互联网使我的工作方便多了。我可以通过电子邮件撰写、编辑并交出我的文章，在网上与我的同事聊天，与老板讨论工作。我用鼠标一击，马上就能拿到我要的一切资料，获得最新的消息。可是，另一方面，用网络通信有时也令人沮丧。系统有可能瘫痪，更糟的是，因为没有面对面交谈的情感提示，键出的词有时候似乎很难理解。
