Classification is made on the basis of a clear definition.5) In order to make a clear and logic classification, one needs to followa principle of classification and go on with a system consistently.For example, the categories of classification should be mutually exclusive and no overlapping is allowed.Reading 1 Causes for Global Warming2. Coal is the most abundant fossil fuel resource. It provides aboutone-quarter of the total energy the world uses, and 40 percent of the electricity generated worldwide is powered by coal. The steel industry also is greatly dependent upon this fossil fuel. Like other depleting sources of global energy, coal reserves are also on a steep decline.Moreover, coal is a greenhouse gas nightmare. Natural gas is comprised mostly of methane, although it also contains ethane, propane and butane.It is a convenient and efficient energy source. The major consumers of natural gas are the residential, commercial and industrial sectors. It is also used to generate electricity. Unlike other fossil fuels, naturalgas is cleaner and causes less pollution.

Id functions on “the Pleasure Principle”, while egoworks on “the Reality Principle” and superego is the internalized rules of a society. Ego is in between id and superego.Task 3 Reading Classification ArticlesReading 2 Renewable Energy Sources—A Brief Summary1. 1) Renewable energy is energy which comes from natural resources suchas sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished).2)□√ The purpose of using renewable energy sources.□√ The classification of renewable energy sources.□√ The examples of different types of renewable energy sources.□√ The advantages and disadvantages of various types of renewable energy sources.□√ The history of the use of different energy sources.□ How energy is obtained from various sources.3) I would write:(1) The definition of the renewable energy.(2) The classification of the renewable energy.(3) The advantages and the disadvantages of various types of renewable energy sources.2. 1) The signing of the Kyoto Treaty.2) It converts the sun’s rays into energy.3) The main demerit is that it is limited.4) Sailors, farmers and architects.5) The main advantage is that this doesn’t produce any by-products thatcan be harmful to the environment.6) Because the Earth’s crust continuously decays, replenishing the heat.7) They use the force of the water to push the turbine which in turn powersa generator thus generating electricity.8) It poses a problem for fish and aquatic plants on both sides of the dam.9) They contain no petroleum, and they are nontoxic and biodegradable.10) The Environmental Protection Agency.3. 1) j. evolution 2) s. solar 3) a. architect 4) l. geothermal 5) p. preserve6) b. biodegradable 7) r. radioactive 8) f. crusade 9) h. distribute 10) q. radiant11) i. domestic 12) t. validation 13) k. generator 14) d. capture 15)g. definitely16) n. install 17) e. consumption 18) m. harness 19) o. internal 20) c. bladeReading 3 Types of Pollution5. 1) voluntary 2) construction 3) contamination 4) eruption 5) regulation6) deforestation 7) yield 8) irrigation 9) confine 10) sewage11) hazardous 12) residential 13) vapor 14) decay 15) erosion16) disrupt 17) particulate 18) underground 19) concentration 20) combat6.7.8.

Fresh food, on the other hand, often comes straight from a farm and has all the nutrients Mother Nature intended for it. As we can see, fresh food offers many benefits that canned food lacks.

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。

Before Korean students take university entrance tests, their friends give them sticky rice candy for luck. The friends hope that the students will pass the test and "stick to" the university. The following short conversations will tell you about different customs in China, Argentina, Switzerland, Italy and Japan.Number 1: ChinaWoman: Did I tell you I'm going to China?Man: China? Great.Woman: Yes. I'm going to Shanghai on business. I have to buy some gifts.Man: Good idea. What are you going to take?Woman: I was thinking of bringing some handkerchiefs. They're colorful, beautiful? also lightweight. I don't want to carryanything heavy.Man: Ah, I don't think you should give handkerchiefs. They aren't a good gift in Chinese culture.Woman: Why not?Man: A handkerchief is a symbol of saying goodbye.Woman: Saying goodbye?Man: Yeah, like when you're going away ... and people are crying, so they need a handkerchief. Actually, I've heard that one of the best things to give is a dinner -- not a present, but a big dinner. It's good for business.Number 2: ArgentinaWoman: This is interesting. Did you know that in Argentina you should never give clothing unless you know the person really well?Man: Don't give clothing? Why not?Woman: Clothing -- even things like ties -- are too personal. Only good friends give them. Man: Huh? I never thought of a tie as being personal ... just uncomfortable. What should you bring?Woman: I don't know. Maybe something for the house.Number 3: SwitzerlandMan: We're meeting Mr. Mertz and his wife for dinner. Maybe I should take flowers or something ... Yeah, I'll pick up some red roses.Woman: You'd better not give them roses. In Switzerland, they could be a symbol of love and romance.Man: Oh, I didn't know that.Woman: I think candy or chocolate might be better.Number 4: ItalyWoman: I'd like some flowers. Uh ... those. About ten, I guess.Man: Ma'am, I don't think you should give ten flowers. In Italy,even numbers -- 2, 4, 6, andso on -- are bad luck.Woman: Even numbers are bad luck? OK, I'll take nine flowers then.Number 5: JapanWoman: May I help you?Man: I'm going to stay with a family in Japan. I need to get something for them.Woman: Pen sets are always a good gift.Man: Oh, that's a good idea. Let's see ... There are sets with a pen and pencil ... and bigger sets with four pens.Woman: You said you're going to Japan?Man: Yeah.Woman: Don't give a set of four pens -- in fact, don't give four of anything.Man: Why not?Woman: The Japanese word for "four" sounds like the word for "death." It's bad luck.Man: Thanks for telling me. I'll take the pen and pencil set.Woman: Good choice. These sets make very good gifts. After all, pens write in any language! Man: Uh ... yeah.

人类历史发展长河中，由于利用能源成本低廉，人们主要关注能源和人类安康关系中有利的一面。
然而，过去一百年以来人口以空前速度增长，引起了能源需求的激增，同时，人均工业能源需求亦急剧增长。
因此，能源利用所需成本越来越高，无论是外延成本还是内涵成本。
一方面，能源资源加速减少，能源供应所需投入越来越高；另一方面，相比之下，外延成本更加令人忧虑，原因是能源利用严重威胁大众健康和安全，不断破坏全球生态系统，并可能引发大规模军事冲突。
C．1. Energy use should benefit global sustainability so that it can contribute to long-term human well-being.2.

To finance her two daughters who are both at college, she began making handicraft to augment the family income.D. It is difficult to quantify the total contribution of all these factors to the monetary costs of energy supply, in part because factors not related to the environment are often entwined with environmental ones. For example, construction delays have been caused not just by regulatory constraints but also by problems of engineering, management and quality control. Nevertheless, in the US, environmental impacts have increased the monetary costs of supplying petroleum products by at least 25 percent during the past 20 years, and the costs of generating electricity from coal and nuclear power by 40 percent or more.Task 2 Vocabulary DevelopmentA. in other words enforced regardless of address involved bordering on applied to suggest convictions availableB. subsequent whopping fatalities sporadically prior to prod turned up whim nail crashTask 3 TranslationB.在感恩节的周末，24小时内发生了2起车祸，撞死3人，使得过去2周里斯普林菲尔德城市道路上死亡人数上升到6人。
