Kitchens on board were using lots of oil， which was often thrown into the water. The growth in tourism also meant the local population rose rapidly， as well as the number of commercial and industrial enterprises.”通过举例，说明游船、旅游业发展带来的人口增长和企业增加等因素是导致水污染的主要原因。 2.此类写作在描述措施时，通常采用列举说明的写作手法，清晰地展现了解决问题的具体做法。如第三段中“A comprehensive initiative was started， with a number of measures that addressed the issues. The construction of waste water treatment facilities improved the water quality and water conservation. The collection and transport of household waste was also improved. Dozens of polluting enterprises were closed or moved.”通过列举具体的行动，如建设污水处理设施、改善垃圾收集和运输、关闭或迁移污染企业等，介绍了解决漓江污染的具体做法。 三、赏语言特色 1.报告的语言较为正式和客观，常使用一些专业术语，如本文中的“tourist destinations” “water pollution”等。 2.通过具体数据来强调问题的严重性，如本文运用“an increasing volume of tourists， many of whom frequently threw garbage into the river”强调了游客数量的增加使漓江的水质严重恶化。 四、学逻辑衔接 此类文体在行文时经常使用很多表示因果关系、阐述问题和措施的词汇或表达方式。本文中使用了以下词汇和表达方式，使文章衔接顺畅，逻辑清晰。 1.Cause and effect:have negative effects on， suffer from， contribute to， in order to， lead to， cause 2.Problems and solutions: (1)Words:improve， close， set up， introduce， spread， carry out，fine， preserve， tackle， head towards (2)Expressions: ①Urgent steps should be taken to ... ②A comprehensive initiative ... ③With a number of measures that addressed ... ④With these measures ... ⑤With such campaigns in effect ... 3.Cohesive words (衔接词):however， furthermore， at the same time， in addition 提能训练/完成句子 ①_________________________ to protect the rare wild animals.  应该采取措施保护珍稀野生动物。 ②A number of measures were taken to _________________________.  为解决这个问题采取了许多措施。 ③________________________， the arts can bring communities together， reducing loneliness and making people feel safer.  此外，艺术可以让社区团结起来，减少孤独感，让人们感到更安全。 Measures should be taken address/tackle the problem Furthermore/In addition 写作项目指导 Write a report on an environmental issue ——写一篇关于环境问题的报告 第一步:构思谋篇 文体 结构 首段 引入话题:点明环境问题及原因 中段 解决环境问题的具体措施 尾段 措施的成效及发起呼吁 时态和人称 以一般现在时和一般过去时为主;以第三人称为主 第二步:要点表达 第一部分:点明环境问题及原因 ①Many beautiful rivers and lakes ______________________ the waste water from factories， and the polluted water even ___________ people as well as other living things.  许多美丽的河流和湖泊已经被工厂的废水污染，被污染的水甚至对人和其他的生物有害。 have been polluted by does harm to ②The environment on our campus ________________________， with rubbish everywhere and a lot of graffiti on the walls.  我们校园的环境过去不太令人满意，到处都是垃圾，墙上乱涂乱画。 used to be unsatisfactory ③__________________， the earth keeps suffering from serious pollution， abuse of resources and illegal hunting，as a result of which， it is not the beautiful planet it used to be.  众所周知，地球长期面临严重污染、滥用资源和非法狩猎等问题，因此，地球不再是过去那样美丽的星球了。 As is known to all ④At present， a great deal of rubbish is produced in some cities， such as leftover food， waste paper， plastic bottles and batteries， ____________________________________________.  目前，在一些城市产生了大量的垃圾，如剩饭、废纸、塑料瓶、电池等，对环境造成了严重的影响。 which has had a bad impact on our environment 第二部分:解决环境问题的具体措施 ①We should recycle and reuse things， for this saves money and _________________.  我们应该回收和重复使用物品，因为这样能节省钱，也能减少污染。 ②__________________， the city government introduced the system of rubbish classification.  为了解决这个问题，市政府出台了垃圾分类制度。 reduces pollution To tackle this issue ③______________________ the factories which pour waste water and the visitors who throw garbage into the lake will get fined.  毫无疑问，向湖里倾倒废水的工厂以及把垃圾扔进湖里的游客将被罚款。 There is no doubt that 第三部分:措施的成效及发起呼吁 1.措施的成效 ①Fortunately， thanks to the launch of Environmental Protection Day， our campus _____________________________ since then. 幸运的是，由于环保日的启动，我们的校园经历了巨大的变化。  has experienced great changes ②___________________________________， now we’re enjoying a cleaner campus， which has become a place where we can study and live comfortably.

Ⅲ.读后续写(25分) 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 Most of us never forget the person that was there for us in our darkest times.Apparently， penguins don’t either. On a typical day， off the coast of a small Brazilian island， Joao Pereira de Souza headed out fishing.He was disheartened to find that an oil leak had polluted the waters.Staring out at the oily waves， he decided it was not a good day to fish.But walking on the beach， he found a struggling penguin， covered in oil and starving. Joao took the penguin home， and spent a whole week gently cleaning it and nursing it back to health.He named it Dindim， a Portuguese word meaning “ice pop”.Dindim is a Magellanic penguin， a species known for living in the seas of South America.In order to breed，it must return to Patagonia， 5，000 miles from Joao’s home. After a week of rehabilitation (康复).Joao patiently took Dindim back to the sea and taught it how to swim again.When Dindim could swim quite well，Joao took it out into the sea by boat and dropped it off to encourage it to swim back to its home.But when he was back to shore， he found the penguin waiting for him.Joao made two more attempts later， but each time Dindim would just return to Joao’s home. It seemed that Dindim had already formed a family bond with Joao and wouldn’t leave. Joao had no choice but to keep the little creature.During the following months， Dindim would follow behind Joao to fish on the coast joyfully.Dindim also liked to lie on Joao’s lap， letting Joao give it showers， allowing Joao to feed it fish and to pick it up.Joao and his family enjoyed the company of Dindim.But deep inside Joao’s heart， he knew Dindim belonged to the wild.Gradually，the hot summer days witnessed the change of its new feathers.Was it time to say goodbye? 注意:1.续写词数应为150左右; 2.请按如下格式作答。 Suddenly one morning， Joao found Dindim disappeared. A few months later， Joao heard some familiar cries in his backyard. 参考范文: Suddenly one morning， Joao found Dindim disappeared. He searched through the house and the coast， and even rowed a boat to the ocean.But the penguin was nowhere to be found.Joao was relieved as he knew it was likely that Dindim had returned to its breeding area in its best condition.However， deep inside he was sad to realize Dindim， whom he regarded as a family member， had already left. When Joao went fishing， he was alone.He was told Dindim would never return， but he still held some hope. A few months later， Joao heard some familiar cries in his backyard.It was Dindim! The moment Joao turned around， Dindim hurried towards him and threw itself into his arms.It traveled 5，000 miles from its breeding area to visit Joao! Happy tears sprang from Joao’s eyes.He just held Dindim up like a baby， ready to bring its favorite fish.The later days saw the house full of laughter again.Since then， Joao has been receiving visits from his feathered friend every year.Human activities may threaten wildlife， but in the special case of Dindim， it is evident that a close relationship can be built between animals and humans. 二、阅读拓展训练 Recycling Electronic Waste When Alex Lin was 11 years old， he read an alarming article in the newspaper which said that people were burying old computers in backyards， throwing TVs into streams， and dumping (丢弃) cell phones in the garbage.This was dangerous because e⁃waste contains harmful chemicals that can leak into the environment， getting into crops， animals， water supplies and people. Alex was really worried and decided to make it next project for WIN — the Westerly Innovations Network.Alex and six of his friends had formed this organization to help solve community problems two years before. But what could they do about this project with e⁃waste? The team spent several weeks gathering information about the harmful chemicals in e⁃waste and their effects on humans.They learned how to dispose of e⁃waste properly and how it could be recycled.Then， they sent out a survey and found only one in eight knew what e⁃waste was， let alone how to properly dispose of it. Alex and his friends went into action.They advertised in the local newspaper and distributed notices to students， asking residents to bring their unwanted electronics to the school parking lot.The drive lasted two days， and they collected over 9，500 kilograms of e⁃waste. The next step was to set up a long⁃term e⁃waste drop⁃off center for the town.After some research， they’d learned that reusing is the best way to deal with electronic devices and it is seven times more efficient than recycling.So， they began learning to refurbish (翻新) computers themselves and distributed them to students who didn’t have their own.In this way， they could help students in the area and protect the environment at the same time. For a lasting solution to e⁃waste， the drop⁃off center wasn’t enough.Laws would have to be passed.In 2016， WIN helped push for an e⁃waste bill in their town， which required companies that manufactured or sold electronics to take back e⁃waste.The bill clearly forbids the dumping of e⁃waste. Because of the work of WIN， more and more people， like Alex and his team， are getting the message about safe disposal of e⁃waste.As Alex says， “Today’s technology should not become tomorrow’s harmful garbage.” 语篇解读:本文是一篇记叙文。文章主要讲述了几个十几岁的年轻人为了避免电子垃圾对环境造成的影响，想办法循环利用电子垃圾的故事。 1.What was Alex’s worry after he read the article?
