2019-2020年高中英语Unit2TheEnvironmentSectionProject教学案牛津译林版必修5Protecting the Yangtze RiverAs the third longest river in the world, the health of the Yangtze River has raised concern both in China and abroad. Rapid development and an increase in population have meant that the amount of water taken from the river is rising, and that the waste being put back into the river has been increasing. This is not good news for the people who rely on the Yangtze River for water. Nor is it good news for the wide range of fish and wildlife that live in or along the river .Many people have recognized the importance of protecting the Yangtze River, and organizations and projects have been set up to deal with the problem. The Green River Organization, for example, educates people on the importance of protecting this great river. It also watches the river and stops the illegal hunting of animals, which has put the wild animal population in danger.the third longest river第三长河raise vt.引起；提出concern n关心，关注in China and abroad在国内外an increase in population人口的增长mean vt.&vi.意味着，意图，打算；意指put .back into把放回rely on依靠，依赖who引导定语从句，修饰先行词the people。rangereIndn范围；一系列；山脉 vi.(在一定范围内)变化；包括；排列，排序wildlife n野生生物nor位于句首时，句子用部分倒装语序。that引导定语从句，修饰先行词fish and wildlife。the importance of doing sth.做某事的重要性set up创立，建立deal with处理watch v监视illegalIliladj.违法的，非法的which引导非限制性定语从句，对the illegal hunting加以补充说明。in danger处于危险中保护长江第12段译文作为世界第三长河，长江的环境问题已经引起了国内外的关注。飞速的经济发展和人口增长意味着取自长江的水量不断增加，而排回到长江中的废物也在不断增加。这对依赖长江用水的人来说是个不好的消息。对生活在江中或沿岸的大量鱼类和野生生物来说也是个不好的消息。许多人已经认识到了保护长江的重要性，他们已经成立组织并设立项目来处理这个问题。例如，绿色江河组织教育人们，让人们了解保护这条大河的重要性。该组织还监视长江，阻止非法捕捞，非法捕捞已经威胁到野生动物的数量。Two special government projects are also under way. The first project, a water and soil conservation project, was set up in 1989. This project resulted in farmers replacing their crops with trees or grass. It has already been a success because it has helped improve the local environment and the land around the river.The second project includes nature reserves for whiteflag dolphins， one of the rarest animals in the world. The number of whiteflag dolphins in China has dropped because of pollution in the Yangtze River. The whiteflag dolphin was last seen several years ago, though scientists are still hopeful that the animal has survived.under way进行中conservationknsveInn(对自然环境的)保护result in导致；引起result from由造成replace crops with trees or grass退耕还林或退耕还草a success一件成功的事；一个成功的人help improve帮助提高nature reserve自然保护区whiteflag dolphinn白鳍豚dolphindlfInn海豚one of the rarest animals最稀有的动物之一the number of .作主语时，句子谓语动词用单数形式。a number of .作主语时，句子谓语动词用复数形式。though引导让步状语从句，其中that引导的从句作hopeful的宾语。第34段译文两个特设的政府项目也在进行中。第一个项目是水土保护项目，启动于1989年。这个项目使得农民退耕还林或退耕还草。这个项目已经取得成功，因为它已经帮助改善了当地的环境和江边的土地情况。第二个项目包括白鳍豚自然保护区。白鳍豚是世界上最稀有的动物之一。由于长江的污染，中国白鳍豚的数量已经减少。尽管科学家还在期盼着白鳍豚不会绝种，但人们最后一次看到白鳍豚已经是在好几年前了。We still have a long way to go to solve all the problems inregard to the Yangtze River. However, people have finally realized that it is their responsibility to protect this great river.Because of this, the situation on the Yangtze River is improving.

Many people blame this change on gases such as carbon dioxide. Animals and humans produce carbon dioxide when they breathe. However, many other human activities alsolet off carbon gases. Anytime something is burnt, carbon is put into the atmosphere. Cars and other vehicles burn petrol in their engines， and electrical power plants most often burn fuels such as coal and oil in order to produce electricity. Therefore, the more petrol and electricity we consume， the more carbon we are letting off.climateklaImtn气候lowcarbonlkbnadj.低碳的There is no doubt that .是固定句式，其中that引导同位语从句。blame .on .将归咎于carbon dioxiden二氧化碳carbonkbnn碳dioxidedaIksaIdn二氧化物let off 排放carbon gases 碳化气体anytime adv.无论何时，任何时候vehiclevikln交通工具，车辆petrolpetrln汽油engineendInn发动机，引擎electricalIlektrIkladj.电的，用电的plantplntn工厂；发电厂fuelfjuln燃料vt.&vi.提供燃料；加油consumeknsjumvt.消耗，耗费；消费the more ., the more .越就越，前者相当于条件，后者相当于结果。表示结果的分句中含有定语从句we are letting off，修饰carbon。气候变化和低碳生活第1段译文毫无疑问，在最近几年里，世界气候一直在变化。许多人将这一变化归咎于二氧化碳等气体。动物和人类在呼吸时会产生二氧化碳。然而，人类的许多其他活动也会释放出碳化气体。每当物体燃烧时，碳就会被排放到大气中。小汽车和其他车辆燃烧汽油来发动引擎，发电站通常靠燃烧诸如煤和油之类的燃料来发电。因此，我们消耗的汽油和电能越多，我们排放的碳就越多。 One thing we can all do to help solve this problem is to walk or use a bicycle when possible. Although we produce carbon when we breathe, the carbon we produce is much less than that produced by a car. Of course, there are times when we need to travel long distances. In this case， public transport such as buses and the underground is always a much better choice than a private car or a taxi. If you must drive a car, it is never good to travel alone you should try to find other people to travel with you.we can all do是省略了that的定语从句，修饰先行词one thing。when possible为省略句，补全应为when it is possible。much less than比少得多travel long distances出远门，长途旅行in this case在这种情况下must 偏偏，偏要never good完全不好，绝对不好if引导条件状语从句，主句中it为形式主语，真正的主语是动词不定式短语to travel alone。第2段译文我们能做的有助于解决这一问题的方法之一就是尽可能步行或使用自行车。尽管我们呼吸时产生碳，但呼出的碳要比一辆小汽车产生的碳少得多。当然，有时候我们也需要长途旅行。在这种情况下，与私家车或出租车相比，公共交通工具如公共汽车和地铁总是更好的选择。如果你偏要开车，独自出行绝不是最佳选择你应该尽量找其他人与你同行。At home, you should use as little energy as possible. Turn off the lights and anything else electrical when not in use .Since factories use a lot of energy and also let off carbon gases, it is important to recycle as much as possible. In particular， metal products and paper products require a lot of energy to produce, so you should find ways to use these again without throwing them away.Last but not least， you can plant a tree, because trees absorb the carbon dioxide in the air to produce oxygen. Planting a small tree is cheap and easy， and two decades from now, when you look at what will have bee a large tree， you will find a sense of satisfaction knowing that you did yourpart to help solve the problem of climate change.as little .as possible尽可能少的turn off关掉when .use为省略句，补全应为when they are not in use。since引导原因状语从句，主句中it是形式主语，真正的主语是不定式短语。in particular 尤其，特别particularptIkjl(r)adj.特指的；特别的；讲究的require vt.需要throw .away 把扔掉last but not least最后但同样重要的是absorbbsbvt.吸收；理解；使全神贯注oxygenksIdnn氧气动名词短语作主语，句子谓语动词用单数形式。decadedekeIdn十年when引导时间状语从句；what引导宾语、从句。a sense of satisfaction 满足感do ones part 尽自己的职责help solve帮助解决第34段译文在家你应该消耗尽可能少的能源。不用电灯以及其他电器时，应该关掉。由于工厂消耗大量能源，也排放出大量碳化气体，尽量多地回收利用是非常重要的。尤其是金属产品和纸质产品需要大量能源来生产，因此你应该找到重复使用这些产品的方法，而不是把它们扔掉。最后但同样重要的是，你可以植树，因为树能够吸收空气中的二氧化碳，释放出氧气。种植一棵小树花费很少也很简单，二十年之后，当你看到它长成大树时，你会有一种满足感，因为你知道你为帮助解决气候变化问题尽了自己的职责。Step 1Read the two texts carefully and choose the best answers.1What environmental problems does the Yangtze River have?AThe waste being put back into the river is increasing.BThe water is unsafe to drink.CThe waste in the river endangers the fish and wildlife living in or along the river.DAll of the above.2Which of the following doesnt belong to the things that the organizations and projects do to protect the Yangtze River?AEducating and advising people on the importance of protecting the river.BWatching the river and stopping the illegal hunting of animals.CAssessing the river and trying to work out possible solutions to many problems.DReplacing the crops on the farmland with trees and grassland.3Which of the following statements about the Yangtze River is TRUE?AWe still have to do many things to protect the Yangtze River.BAll people have realized the importance of protecting the Yangtze River.CThe environmental situation of the Yangtze River has improved a lot.DOnly the people who have worked for the protection can appreciate our work.4To help decrease carbon gases, one should.Anot travel long distanceBnever travel aloneCalways walk or ride a bikeDuse as little energy as possible5What is the best way to use energy?ANever turning on the lights.BRecycling.CMaking things by hand.DNever throwing things away.答案：15DDADBStep 2Fill in each blank with no more than three words according to the texts.TopicProtecting the Yangtze RiverClimate change and a lowcarbon lifeProblemsThe amount of water taken from the river is on the 1.rise/increase.More and more waste is being dropped into the river.Wild animals are being hunted illegally.The world climate has been 6.going through great changes in recent years.2.Causes/ReasonsThe industry is developing fast and the population is increasing.Some people fail to 3.realize/recognize the importance of protecting the river.An increasing number of human activities, especially burning things, driving vehicles and producing electricity, lead to more carbon gases being 7.letoff/givenoff.SolutionsThe Green River Organization provides the public with 4.education about the importance of protecting the river, watches the river and protects animals from being hunted illegally.Two special government projects 5.focusingon the water, soil conservation and nature reserves for whiteflag dolphins are under way.Go on foot or ride a bike when possible.
