课时冲关12　Unit 6　Earth first Ⅰ.阅读理解 主题：人与社会 体裁：议论文 话题：减少包装，保护环境 Cotton bags have become a means for brands，retailers，and supermarkets to promote a planet­friendly concept — or，at least，to show that the companies are aware of the overuse of plastic in packaging.“There's a trend in New York right now where people are carrying cotton bags from local bakeries，hardware stores，or their favorite steakhouses，” said designer Rachel Comey. So far，so earth­friendly? Not exactly.It turns out the wholehearted embrace of cotton bags may actually have created a new problem. An organic cotton bag needs to be used 20,000 times to offset (抵消) its overall impact of production，according to a 2021 study by the Ministry of Environment and Food of Denmark.That is equal to daily use for 54 years — for just one bag.Even when a bag does make it，most coloring matters used to print logos and decorations onto them are PVC­based and thus not recyclable in waste treatment factories. That's not to say cotton is worse than plastic，or that the two should even be compared.While cotton can use pesticides and has dried up rivers from water consumption，lightweight plastic bags use greenhouse gas­emitting fossil fuels，never break down，and block up the waterways. Some brands are turning to other fabric solutions.British designer Ally Capellino recently swapped cotton for straw，while designer Anya Hindmarch introduced a new version of her original bag，this time made from recycled water bottles.In the end，the simplest solution may be the most obvious.“Not every product needs a bag，” Comey said. [语篇解读]　本文是议论文。文章讨论了使用棉布包并没有大家所想的那么环保。 1．Why on earth do companies offer cotton bags? A．To provide convenience to their customers. B．To cut down on the use of plastic packaging. C．To advertise themselves as eco­friendly ones. D．To promote the concept of protecting the earth. 解析：C　[细节理解题。根据文章第一段中的“Cotton bags have become a means for brands，retailers，and supermarkets to promote a planet­friendly concept—or，at least，to show that the companies are aware of the overuse of plastic in packaging.(棉布包已经成为品牌、零售商和超市宣传保护地球观念的一种方式——或者至少是展现出这些公司已经意识到了塑料包装的过度使用)”可知，这些公司提供棉布包的本质目的是想要标榜他们是环保企业。] 2．What do we know about the cotton bags? A．They can be used for over five decades. B．They do much harm to the environment. C．They have logos printed with natural materials. D．They can be recycled in waste treatment factories. 解析：B　[推理判断题。根据文章第二段中的“So far，so earth­friendly? Not exactly.It turns out the wholehearted embrace of cotton bags may actually have created a new problem.(到目前为止，如此环保吗？不尽然。事实证明，全心全意地接受棉布包可能造成一个新问题。)”以及第三段中的“An organic cotton bag needs to be used 20,000 times to offset (抵消) its overall impact of production，according to a 2021 study by the Ministry of Environment and Food of Denmark.(根据一份丹麦环境食品部门2021年的研究表明，一个有机棉布包需要被使用两万次才能抵消它在生产过程中所产生的全部影响。)”可知，到目前为止，使用棉布包听上去很环保，但事实并非如此。我们全心接纳的棉布包实际上产生了新的问题。根据丹麦环境食品部门2021年的研究表明，一个有机棉布包需要被使用两万次才能抵消它在生产过程中所产生的全部影响，由此可知，棉布包可以对环境造成巨大影响。] 3．How does the production of plastic bags affect the environment? A．It consumes too much water. B．It saves the use of fossil fuels. C．It pollutes the earth's atmosphere. D．It increases the use of pesticides. 解析：C　[细节理解题。根据文章第四段中的“While cotton can use pesticides and has dried up rivers from water consumption，lightweight plastic bags use greenhouse gas­emitting fossil fuels，never break down，and block up the waterways.(虽然棉花使用杀虫剂，并使河流因用水而干涸，但轻型塑料袋使用会排放温室气体的化石燃料，永远不会分解，并堵塞水道。)”可知，轻便的塑料袋使用会排放出温室气体的化石燃料，无法分解，同时会阻塞河道，由此可知，塑料袋的生产会以污染大气的方式影响环境。] 4．Which might be the best title for the text? A．Plastic Bags Beat Cotton Bags B．A Revolution for Bag Designers C．How to Choose Bags for Yourself D．Less Packaging，Better Environment 解析：D　[主旨大意题。根据全文内容以及文章第五段中的“In the end，the simplest solution may be the most obvious.‘Not every product needs a bag，’ Comey said.(最后，最简单的解决方案可能产生的效果是最明显的。科米说，并不是每个产品都需要一个包。)”可知，全文探讨了棉布包给环境带来的影响和危害，同时提出最简单的解决办法产生的效果也是最明显的，即并非所有的产品都需要一个袋子，由此可知，本文的最好标题应为“减少包装，保护环境”。] Ⅱ.语法填空 主题：人与自然 体裁：说明文 话题：新型可降解的塑料 Plastic has polluted the countryside and been 1.________ threat to wildlife for decades.In the last century or so，environmentalists have urged us 2.________(cut) the amount of plastic we use or recycle the plastic bags.However，with only less than 14 percent of the total amount recycled，people are still struggling with plastic pollution 3.________(global)． There may be a solution.Recently scientists have made a biodegradable (可降解的) plastic，4.________ means the billions of plastic bags，cups，straws，etc.that we throw away each day could be recycled.5.________(compare) with ordinary plastics，they could break down as naturally as organic waste.They could do it within a few weeks,6.________(use) just heat and water.The new，biodegradable plastic has polyester­eating enzymes (酶) inside it. When these enzymes are exposed 7.________ heat and water，they eat away at the plastic and turn it into “food” for the soil.Professor Ting Xu said up to 98 per cent of the plastic her team made reduced into tiny pieces. She said: “The study gives us a belief that this continuing problem of single­use plastics can 8.________(solve) in the near future.” She added: “Look at all the 9.________(waste) stuff we throw away—clothing，shoes，electronics...We are taking things from the earth at a 10.________(fast) rate than we can return them.” [语篇解读]　本文是说明文。文章主要介绍了一种新型可降解的塑料可以降低塑料带来的危害和污染。 1．a　[考查冠词。句意：塑料污染了农村，几十年来一直威胁着野生动物。此处泛指一个威胁，应用不定冠词来修饰，且threat发音是以辅音音素开头，故填a。] 2．to cut　[考查非谓语动词。句意：在上个世纪左右，环保人士敦促我们减少塑料的使用量或回收塑料袋。urge sb.to do sth.固定搭配，意为“催促某人做某事”，故填to cut。] 3．globally　[考查副词。句意：然而，只有不到总量的14% 的塑料被回收，人们仍然与全球塑料污染斗争。此处应用副词globally作状语，故填globally。] 4．which　[考查定语从句。句意：最近科学家们做了一个生物可分解塑料，这意味着我们每天扔掉的数十亿个塑料袋、杯子、吸管等等都可以被回收利用。空处引导非限制性定语从句，先行词为上文整个句子，且关系词在从句中作主语，应用关系代词which引导定语从句，故填which。] 5．Compared　[考查非谓语动词。句意：与普通塑料相比，它们可以像有机废物一样自然分解。此处是非谓语动词在句中作状语，主语they和动词compare是被动关系，应用过去分词作状语，单词位于句首，首字母大写，故填Compared。] 6．using　[考查非谓语动词。句意：他们可以在几个星期内完成，只需要热量和水。此处是非谓语动词作状语，主语they和动词use是主动关系，应用现在分词作状语，故填using。] 7．to　[考查固定搭配。句意：当这些酶暴露在热和水中时，它们会侵蚀塑料，并把它变成土壤的“食物”。be exposed to固定搭配，意为“暴露于”，故填to。] 8．be solved　[考查语态。句意：她说：“这项研究让我们相信，一次性塑料这个持续存在的问题可以在不久的将来得到解决。”that引导的同位语从句中，主语problem和动词solve是被动关系，由情态动词can可知，此处应用be solved。故填be solved。] 9．wasted　[考查形容词。句意：她补充说：“看看我们扔掉的那些被浪费掉的东西——衣服、鞋子、电子产品……。”此处应用形容词wasted作定语，修饰名词stuff，故填wasted。] 10．faster　[考查形容词比较级。句意：我们从地球上拿走东西的速度比我们还回去的速度还要快。由than可知，此处应用形容词fast的比较级faster作定语，修饰名词rate，故填faster。] Ⅲ.读后续写 主题：人与社会 体裁：记叙文 话题：植树改变荒地 阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。 I met the Man of the Trees in summer ten years ago，when I was visiting Uncle Jita. Those were difficult times.People were cutting down our forest，and there was often flooding.Sometimes our water supply was dirty.When our pump(水系) did have clean water we had to wait in line for ages.When the pump wasn't working，we had to walk five kilometres to the closest stream. But I was happy.I was going to see my favorite uncle.When the day finally arrived，Dad drove me to Uncle Jita's house and left.Once he saw me，Uncle Jita announced，“Tomorrow we're going to explore a magical place.Here is my camera，Amy.You can take photos of what you see.” The following day，we woke up and left early on a boat.The trip was exciting.But when we got off，there was ...nothing in front of us.“I don't want to take pictures of this，”I complained. Uncle laughed，“Start walking，Amy.I promise you'll be surprised.After some time，I could see the outline of a forest in the distance.A little closer，there was a man waving to us. “That's Kabir.The forest you see is his.He planted every single tree.” As we walked towards Kabir，Uncle explained that thirty years ago，the whole area was a wasteland.But one day Kabir decided to change all that and started planting trees.Thanks to him，part of the wasteland is now a paradise(天堂)． Uncle introduced me to Kabir，who had gray hair and a determined face.“Jita told me you like animals.Are you ready to see some？” he asked.“Of course！”I replied.We continued walking and soon were under the trees.I turned my head and was amazed at the difference between the two places.All because of the efforts of one man. Like Uncle said，Kabir's forest was magical.We saw deer，rhinos，and even tigers.During lunchtime，Kabir explained how，by planting trees，it was possible to stop the land from eroding(侵蚀)． 注意： 1．续写词数应为150左右； 2．请按如下格式在相应位置作答。 Hearing this，I turned to my uncle，“I think we can plant trees too.________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ In the years that followed，people in our village worked hard to carry out our plan.______ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ [参考范文] Hearing this，I turned to my uncle，“I think we can plant trees too.”Grabbing the camera in my hand，I added with excitement，“I've got a plan! I'll show them the photos of Kabir's magical forest！” Seeing Uncle and Kabir's encouraging smile，I immediately set down to work，busy pressing my shutter.When Uncle and I went back to the village and showed these wonderful pictures to my neighbors，they were stunned by the beauty of the forest.“It was the trees that turned the place into a paradise！” We then explained our tree­planting plan to the villagers，which was quickly accepted by all of them. In the years that followed，people in our village worked hard to carry out our plan.Instead of cutting down our forest，we started to plant trees，which has eventually helped protect the soil and stopped the land from eroding.Thanks to the trees，the water has been purified and we finally have clean and stable water supply.With our joint efforts，our village is now surrounded by small thriving forests with blooming flowers，lively animals and crystal­clear streams running through.Witnessing the gradual change of our village，we've come to realize that only when we live in harmony with nature can we have a brighter future. 学科网（北京）股份有限公司 $$
