第一篇:My understanding of Success(大学英语)
Bill gates who is one of the world’s richest and most famous businessmen is a really successful man who hundreds of students and workmen send email each year asking for advice about success.With the society which is more and more competitive developing, everyone strongly want to be a man who owns wealth and is eager for success in career.In this case, people who have become blind and numb are very likely to lose themselves in the quest of success.As a result, they could never make it.Thus, I would like to show my own understanding of success helping whoever get confused in the pursuit of success to hold a positive attitude towards it.To begin with, as far as I am concerned,success simply means that through doing something meaningful contributing to others or the society, a person ultimately realizes his value of life and get sublimation in spirit.To be exactly, success never implies how much money you have earn or how high the position you are in but means your intrinsic value that can only be recognized by yourself.Furthermore, some convincing examples can confirm my idea well.For instance, because of setting up the theory of relativity which accelerated the development of science and
finally changed the whole world, Albert Einstein was undoubtedly regarded as one of the world's most famous and successful physicist.As is known to us, the contrition he had ever made to our society is surely respectable and moved us deeply.However, on the other hand, a number of businessmen merely aiming at making money and plundering the wealth from the society often lead to unfairness and chaos around the world which severely jeopardize the safety of the globe.As a result, people like them couldn’t be regarded as a success no matter how considerably money they own.That is to say, whether you can be successful or not is merely measured by the contrition you have made to the world.Last but not least, in order to become successful in life, it is high time we paid attention to charity, environment protection, public welfare, social assistance, emergency assistance and so on to show our love and spare no effort to contribute to our society.Only in this way can we surely approach to success.

快速阅读 What are genetically modified GM foods?
Man has been “genetically modifying” everything from food to dogs for many centuries;but in the past, the only tool has beenselective breeding.For example, if you wanted to create a breed of corn with resistance to a certain fungus, you would plant a plot of corn and see how individual plants did with the fungus.Then you would take seeds from the plants that did well, plant them, look at their performance against the fungus… and so on over the years until you had created a strain of corn plant that had very high resistance to the fungus in question.Using selective breeding techniques, people have created everything from variegated roses to giant pumpkins to strains of wheat with twice the yield and very high disease tolerance.In the same way, you can take chickens, analyze their eggs and find chickens with eggs that contain less cholesterol.Then you can breed them to create a strain of low-cholesterol chickens.You can select on any detectable trait and selectively breed members of the species that do well on that trait.Genetic engineering techniques now allow scientists to insert specific genes into a plant or animal without having to go through the trial-and-error process of selective breeding.Genetic engineering is therefore extremely rapid compared to selective breeding.With genetic engineering, you can also cross species very easily(for example, you can create a plant that produces human insulin).You can read the article How Cells Work to learn about DNA, genes and gene splicing.The techniques are now standard and genes can be spliced very easily.There are a variety of techniques used to modify plants and animals through genetic engineering.For example, there is a widely used herbicide called Roundup, made by Monsanto.Roundup kills any plant that it touches.Monsanto has genetically modified soybeans and other crop plants to create “Roundup Ready” strains that are not affected by Roundup.By planting Roundup Ready seeds, a farmer can control weeds by spraying Roundup right over the crop.The crop completely ignores the herbicide, but the weeds are eliminated.Roundup Ready seeds reduce production costs and increase yield, so food becomes less expensive.Other scientists have inserted genes that produce a natural insecticide into corn plants to eliminate damage from corn borers, and a variety of anti-fungal genes can be inserted as well.The list goes on and on--there really is no limit to what can be done.转基因转基因食品是什么?
男子“基因改造”从食物到许多世纪的狗;但在过去,唯一的工具beenselective繁殖。例如,如果你想创建一个玉米品种抗某种真菌,你会开辟出一块玉米,看看株真菌。然后你将种子的植物表现不错,工厂,看看他们的表现对真菌…等等这些年来,直到您已经创建了一个应变非常高的玉米植株抵抗真菌的问题。
通过选择育种技术,人们创造了一切,从玫瑰组合巨型南瓜品种的小麦产量和非常高的疾病公差的两倍。同样地,你可以把鸡,分析他们的蛋和鸡鸡蛋含有胆固醇。然后你就可以繁殖出的低胆固醇鸡。你可以选择在任何检测特征和选择性繁殖的物种成员做好特质。
基因工程技术现在允许科学家将特定基因插入植物或动物,而无需通过选择育种的试错过程。因此,基因工程是极其快速的选择育种,基因工程相比,你也可以很轻易跨越物种(例如,您可以创建一个工厂,生产人胰岛素)。你可以阅读这篇文章细胞如何工作了解DNA,基因和基因剪接。现在的技术标准和基因很容易可以拼接。
有各种各样的方法来修改通过基因工程植物和动物。例如,有一个广泛使用的除草剂叫农达,由孟山都。综述杀死任何植物,它触动。孟山都转基因大豆和其他农作物创造“农达”压力,不受综述。通过种植抗农达种子,农民可以通过喷洒控制杂草集拢在作物。作物完全忽略了除草剂,但杂草消除。抗农达种子降低生产成本,提高产量,所以食物变得更便宜。其他科学家基因产生天然杀虫剂插入玉米植物从玉米螟虫,消除损伤和各种抗真菌基因也可以插入。这样的例子不胜枚举,——实际上是没有限制的可以做什么。

I.Lesson 3
Background information
A.About the author
Richard MoranMore Crime and Less Punishment
Richard Moran is a criminologist and a leading expert on the insanity defense,capital punishment, and the history of the electric chair.The author of numerous
articles and reviews, Moran has also written articles for the Washington Post,Christian Science Monitor, New York Times, and Newsweek.The Executioner's Current
It is the story of how the electric chair developed out of an effort by one nineteenth-century
electric company to discredit the other.EdisonEdison, Thomas Alva(1847-1931)a US inventor who made over 1300 electrical inventions, including the , the record player, and equipment for the cinema.He is most famous for inventing the(=a glass container with a thin wire inside, which produces light by using electricity).When Thomas Edison and George Westinghouse(1846-1914, 美国发明家)were building the first power plants in the country, electric light was a bizarre new technology that few people understood and many people feared.Adding to the confusion were the two competitors' attempts to promote their own systems and discredit the other.When New York State began considering electrocution as a method of capital punishment, Edison recommended Westinghouse's alternating current for the unseemly task.Westinghouse, not wanting the negative stigma associated with his system, fought back, and a truly well intentioned government effort to find a more humane method of execution became a courtroom battle for commercial supremacy between two competing pioneers.Moran's account is broad, covering the electric power struggle between Edison and Westinghouse, the trial and execution of the first man to die in the electric chair, and the history of the capital punishment debate in the U.S.Edison's popularity as a cultural hero lends appeal to the entertaining drama of the power companies' competition, and the surprisingly colorful history of the electric chair makes for fascinating reading.

08/09学年教学与管理安排
按照外语学院大学英语教研室期中教学、教务会议精神,和近期各学院及师生对教学反映。我们对大学英语08/09学年教学与管理作如下安排:
1、06级“英语视听说”教材使用《新世纪大学英语视听说》(上海外语教育出版社)第3、4册。上课地点:各语言实验室。
2、在07级“综合英语”和“口语”课程中增加授课内容:“翻译和写作”;翻译教材使用毛荣贵教授编写的《新世纪大学英汉翻译教程》(上海交通大学出版社)。每周课型设计:“综合英语”2节+“口语+翻译和写作”2节。
3、08年级普通本科(除音乐、体育、美术类本科外)教学环节细述如下:
1)、普通本科继续实施网络教学。对新生入学时进行分班教学,分A、B、C三种类型。分班原则:浙江省考生按照高考分数分班,外省新生按照A班占1/4,B班占1/2,C班占1/4的比例,将学生划入各模块教学班。所用教材与07级相同。不过教学计划应重新编写,选择合适的章节授课。期末统一出卷。
2)、在“口语”课中增加与专业和时事相关的口语练习内容,任课教师协作编写口语练习教材,教学过程应体现地方性综合大学的特点。同时落实课内“快速阅读”练习。
3)、音乐、体育、美术类本科学生按照传统行政班级教学,每周4节课。教材使用上海外语教育出版社全新版大学英语预备级(底起点+高起点)和综合教程第一、二册全套(综合英语、阅读、视听说、快速阅读)。期末统一出卷。
4)、08专生本的班级按照教学行政班级,不参加网络模块教学班。教材使用大学英语全新版第3、4册的“综合英语”、“阅读”、“视听说”、“快速阅读”。每周4节课。时间1学年,期末单独出卷。
5)08学前专科、08体育高职按照教学行政班级教学教材使用大学英语全新版预备级(底起点+高起点)“综合英语”、“阅读”、“视听说”、“快速阅读”。每周4节课。时间1学年,期末单独出卷。
4、认真总结一年来网络教学改革,努力撰写教学科研论文。教研室将对诸如论文版面费给以适度补贴。

请求增加口语教室数量的要求
根据一年来大学英语口语教学的现状。为确保08年级网络教学改革,经核实应增加多媒体大学英语口语教室如下:
学院路:1个(原1个)
茶山南校区:1个(原3个)
请教务处、现代教育技术中心与外语学院合作讨论有关事项。
