Unit1EconomicsText A:Lead-in:omittedCritical reading and thinking:Task1:Body:Use the labor and skills behind the Thanksgiving weekend as examples to illustrate the concept of“the invisible hand”End:Echo the beginning,emphasizing we should be grateful to the miracle on this Thanksgiving Day and every dayTask2:1.It is not difficult at all to explain why grocery stores stock up on turkey before Thanksgiving.There seemsto be no miracle in it.2.The use of so many“and’s”helps to emphasize that a series of actions and all kinds of work are involved inthe sale of Thanksgiving turkey.3.Here“from above”means“from God”.The phrase is used to show that there is something wondrous andalmost inexplicable in the social order of freedom.Task3:Market has its own way of punishing business malpractice.For example,if a fast food chain sells contaminated food,nation-wide demand for their food will go down,along with their profit.When a company sells defective products,they have to deal with liability costs.Language building-up:Task1:1．1．饲料经销商；饲料批发商2．为他自己的收益而工作3．技能与劳动力4．制造塑料5．私人交易6．包装并定价7．无形之手2．1.pricedbor3.transactions4.gainbor;manufactured6.the invisible hand7.distributorTask2:1.Today,in millions of homes across the nation,God will be thanked for many gifts,for the feast on thetable and the company of loved ones,for health and good fortune in the year gone by,for peace privilege of having been born—or having become—American.(Line2,Para.1)2.And yet,isn't there something wondrous—something almost inexplicable—in the way your Thanksgivingweekend is made possible by the skill and labor of vast numbers of total strangers?(Line1,Para.4)3.…Thanksgiving Turkey,there would be one—or more likely,a few dozen—waiting.(Line3,Para.6) Task3:1.very many2.buying or selling3.a large group of4.more huge5.understand6.troubledText B:Critical reading and thinking:Task1:1.Considering that her boyfriend doesn’t even bother to choose a gift for her,the girl concludes that hedoesn’t love her.Therefore,she breaks off the relationship.In the case where the strength of affection is most in question,people care a lot about what is given as a gift.2.The following is one more example where the signaling theory can be applied:In the job market,anemployer may not know whether a candidate is qualified for a post or not.Very often,the candidate will show the employer education credentials,which can be used as a signal to the employer.Thus the information gap is narrowed.Task2:(以下所有表格题若未说明，顺序皆为从上到下，从左到右)Internet browser;Windows operating system;deter;entering the market and offering new products;cars today include many built-in products;monopoly;80;reliable;easier to use;severely limited;changing;competitors;low;Researching:The U.S.economy is a free market economy with some government regulation ad there has been a lasting debate about how much government regulation is necessary.Those who argue for less regulation claim that the free market itself will require business to protect consumers and provide good products or services and the interference from the government can do nothing but increase the cost of doing corporations are not concerned about the public’s interest,so regulation is indispensable.Interestingly, Adam Smith himself believed that government had an important role to play in economic life.For example, he believed that the government should enforce contracts and grant patents and copyrights.Text C:Task:每一个精明的一家之主都知道，如果买一样东西所花的钱比在家里自己生产所花的成本要小，那就永远不要尝试在家里生产。

研究生英语读写译教程1-18 单元 翻译练习答案
研究生英语读写译教程1-18 单元翻译练习答案Unit 1: Introduction to Translation1. Translation is the process of transferring meaning from a source language to a target language. It involves interpreting and expressing the original message accurately and effectively in the target language.2. Translators need to have a solid understanding of both the source and target languages, as well as a deep knowledge of the subject matter being translated. They must be able to capture the nuances and cultural references present in the source text and convey them appropriately in the target text.3. There are different types of translation, including literary translation, technical translation, legal translation, and scientific translation. Each type requires specific skills and expertise to ensure accurate and contextually appropriate translations.4. Translation involves more than just linguistic skills. Translators must also possess strong research and analytical skills, as well as the ability to adapt to different writing styles and cultural norms.Unit 2: Basic Translation Techniques1. Literal Translation: This technique involves translating each word and phrase literally, without considering the context or cultural nuances. While it may result in accurate translations, it often fails to capture the true meaning and intent of the original text.2. Cultural Equivalence: This technique focuses on finding equivalent expressions or idiomatic phrases in the target language that convey the same meaning as the source language. It takes into account the cultural and linguistic differences between the two languages.3. Adaptation: This technique involves modifying or adjusting certain elements of the source text to ensure a smoother and more natural translation in the target language. It may involve changing sentence structures, idioms, or cultural references to match the target audience.4. Localization: This technique is commonly used in the translation of software, websites, and marketing materials. It involves adapting the translation to the local cultural and linguistic conventions of the target audience. It may include changing date formats, currency symbols, or using region-specific idioms.Unit 3: Translation Strategies1. Skopos Theory: This theory emphasizes the purpose or intention behind the translation. It suggests that translators should prioritize the specific function the translated text will serve, rather than adhering strictly to the source text. The focus is on achieving the desired communication effect for the target audience.2. Text Analysis: Before translating a text, translators should thoroughly analyze its content, structure, and intended audience. This analysis helps to identify important concepts, key terms, and ensure accurate and effective translation.3. Transcreation: This strategy is commonly used in advertising and marketing translations. It involves recreating the source text in the target language while considering cultural and linguistic differences. The goal is to evoke the same emotional response in the target audience as the original text.4. Compensation: Sometimes, certain elements of the source text cannot be fully translated into the target language due to linguistic constraints. In such cases, translators may compensate by adding additional information, footnotes, or explanations in the target text, ensuring that the overall meaning is conveyed accurately.Unit 4: Translation Quality Assessment1. Accuracy: A high-quality translation must accurately convey the meaning and intent of the original text. It should not contain errors, omissions, or distortions that may lead to misunderstandings.2. Fluency: The translated text should be fluent and natural in the target language. It should read smoothly and maintain coherence and cohesion. Awkward phrasing or unnatural word choices should be avoided.3. Cultural Appropriateness: Translations should take into account cultural differences and context. They should be culturally appropriate and avoid causing offense or misunderstanding in the target culture.4. Terminology Consistency: Consistency in terminology is crucial, especially in technical or specialized translations. The translator should use consistent terminology throughout the text to ensure clarity and accuracy.In conclusion, translation is a complex task that requires linguistic proficiency, cultural understanding, and subject matter expertise. Byemploying appropriate techniques and strategies, translators can produce high-quality translations that effectively convey the message from the source language to the target language.。

Training and Practice for English for Academic PurposesPart I1.Discuss the following questions.What are basic principles the researchers must try to follow when they write their research papers? And would you please list some deadly sins a researcher must avoid when they want to publish a research paper? What are the main contents of a research paper?2. Translate the following Chinese introduction into English.提高起重机生产力和安全性的设备研究近些年来，就用研究人员对起重机(crane)的研究兴趣与日俱增。
起重机种类繁多，从樱桃采摘机(cherry pickers)到巨型塔式起重机(huge tower cranes) ，是建筑工地不可或缺的重要设备之一。
由于建筑用起重机工作环境多变(constantly changing working environment), 操作者(operator)责任重大(heavy reliance)。
过去几十年里，超重机技术日新月异，但是操作员与其他工种人员配合协作方面的技术发展缓慢。
起重机的发展步伐如此迅猛，我们似乎要问，在某些方面，是不是已经超出(outstrip)了人们安全使用的能力？本文旨在探讨如何通过新型设备的引进提高起重机生产力以及提出相关安全性的举措，进而为新型起重机的应用和案例提供新的思路。
In recent years, researchers have become more interested in crane research. The variety of cranes, from cherry pickers to giant tower cranes, is one of the most important equipment on construction sites. As a result of the changing working environment of the construction crane, operator is responsible for heavy reliance. Over the past few decades, the technology of overweight machines has been changing rapidly, but the operators have been slow to cooperate with other workers in collaboration. The pace of development of cranes is so rapid that we seem to be asking whether in some respects, the outstrip has exceeded the ability of people to safely use it. This paper aims to explore how to improve crane productivity and raise related security measures through the introduction of new equipment, so as to provide new ideas for the application and case of new cranes.3. You are writing a research paper entitled “The Effects of Radiation from the Sun on Life o n Earth”. In your introduction you need to review, in general terms, how the sun supports life on the earth. Prepare an Introduction section for your paper based on the information below.⏹Distance from the earth: 92,976,000 miles⏹The Sun’s energy comes from nuclear fusion of hydrogen t o helium.⏹Intense radiation, including lethal ultraviolet radiation, arrives at the earth’s outer atmosphere.⏹Ozone in the stratosphere protects life on earth from excessive ultraviolet radiation.⏹The seasons of the earth’s climate results from (1) the 23.30tilt of the earth’s axis of rotation from the normal to the plane of the earth’s orbit around the Sun, (2) the large coverage area of water on the earth (about 75% of the earth’s surface), and (3) the rotation of the earth with associated generation of jet-stream patterns.⏹Radiation passing through the earth’s atmosphere loses most short-wave radiation, butsome arriving at the surface is converted into infrared radiation which is then trapped by water vapor and other tri-atomic molecules in the troposphere and stratosphere, causing global warming.Life on earth is maintained from photosynthesis and conversion of carbon dioxide to oxygen by plants.4.Translate the following parts of sentences in Introduction into proper English.（1）过去对……的研究工作说明……The previous work on … has indicated that…（2）A在1932年做了关于……的早期研究。
