Section Ⅱ　Learning About Language A few minutes later，the other two cyclists arrived.They were shocked to find Mac's bicycle lying on the road，his tent bag torn and Mac just like a drowned mouse.They asked anxiously ①what on earth had happened.Mac responded breathlessly that ② he was almost eaten by a wolf.When told about ③ what Mac had experienced，they couldn't help screaming out，“What a narrow escape！”“Yes，without their timely help，I would have been the food of the wolf.”Mac's friends were also thankful to Paul and Becky.Afraid that there might be more potential dangers ahead，Paul and Becky asked kindly ④whether/if they were in need of a lift.Mac and his friends answered with one voice，⑤“We'd love to.” 直接引用某人的原话叫直接引语，如加黑处⑤，通常前后要加引号；用自己的话转述某人的话叫间接引语，如加黑处①②③④，在多数情况下构成宾语从句。 直接引语和间接引语 直接引语变为间接引语，被转述的分句(即宾语从句)的某些限定词、人称、时态、状语、个别指示代词和动词等方面需做相应的变化。 一、句式的变化 1．直接引语是陈述句 变为间接引语时，常变成由that引导的宾语从句。在口语中that可以省略。引述动词如果是say to或said to，常相应地改为tell或told。 ①The little boy said，“I was playing with my toys when someone knocked at the door.” →The little boy said (that) he was playing with his toys when someone knocked at the door. ②She said to me, “I came back an hour ago.” →She told me (that) she had come back an hour before. 2．直接引语是疑问句 (1)直接引语是一般疑问句、选择疑问句或反意疑问句时，间接引语中用whether(...or...或…or not)或if引导。疑问语序改为陈述语序。引述动词如果是say或said，常相应地改为ask或asked。 Mother said to her daughter，“Are you satisfied with your new room？” →Mother asked her daughter whether/if she was satisfied with her new room. (2)若直接引语是特殊疑问句，则间接引语仍用原句中的特殊疑问词来引导，其余的变化遵照直接引语和间接引语之间的转换规则来进行。但要注意把疑问语序变成陈述语序。 “When will the sports meet be held？”he said. →He asked when the sports meet would be held. 3．直接引语是祈使句 (1)如果直接引语表示要求和命令，变间接引语时常采用ask/tell/order sb to do sth的形式。 “Follow his instructions，”she said to me. →She told me to follow his instructions. (2)如果直接引语表示建议、提议，变间接引语时多采用suggest＋doing/that从句(如suggest后接that从句，从句使用虚拟语气“should＋动词原形”，should也可省略)、offer to do和ask/advise/want sb＋to do等结构。 Jack said，“Let's go to the cinema tonight.” →Jack suggested that we should go to the cinema that night. →Jack suggested our going to the cinema that night. (3)如果直接引语是表示请求的祈使句，变间接引语时，常用ask、beg等动词转述。 My daughter said to me, “Please don't leave me alone at home.” →My daughter begged me not to leave her alone at home. (4)如果直接引语是表示警告或提醒的祈使句，变间接引语时，常用warn、remind等动词转述。 Tom said to me, “Don't forget to buy that book.” →Tom reminded me not to forget to buy that book. (5)如果直接引语中祈使句是否定形式，变间接引语时，不定式符号to前要加not或never。 She said，“Don't make so much noise，children！” →She told the children not to make so much noise. 【点拨】　引述原话为祈使句的直接引语转换成间接引语时，注意直接引语中如果有please，间接引语中需要省去。 The old man said to Lily, “Please read the letter to me.” →The old man asked Lily to read the letter to him. ————即学即练1———— 将直接引语改为间接引语 ①Cathy always says，“I'll do it better next time.” →Cathy always says that she'll do it better the next time. ②Sarah asked，“What were you doing from nine to eleven this morning？” →Sarah asked me what I was doing from nine to eleven that morning. ③I asked him，“Will you stay at home or go to a film tonight？” →I asked him whether he would stay at home or go to a film that night. ④The teacher said to the boy，“Open the door，please！” →The teacher told the boy to open the door. 二、人称的变化 直接引语变为间接引语时，人称代词要根据转述人立场的变化作相应的改变。 1．“一随主”，指在直接引语变间接引语时，如果直接引语中的主语是第一人称或被第一人称修饰，从句中的人称要按照主句中主语的人称变化。 Mary said，“I want to have a computer of my own.” →Mary said that she wanted to have a computer of her own. 2．“二随宾”，指直接引语变间接引语时，若直接引语中的主语及宾语是第二人称或被第二人称修饰，从句中的人称要跟引号外的主句的宾语一致。 Her colleague said to her，“Who did you ask for a leave？” →Her colleague asked her who she had asked for a leave. 3．“第三人称不更新”，指直接引语变间接引语时，如果直接引语中的主语及宾语是第三人称或被第三人称修饰，从句中的人称一般不需要变化。 The workers said，“The leaders often make the workers work extra hours.” →The workers said that the leaders often made the workers work extra hours. ————即学即练2———— 把下列句子改为间接引语，注意人称变化 ①He said，“She will come here to have a long holiday.” →He said that she would go there to have a long holiday. ②She said to me，“You play basketball better than me.” →She told me that I played basketball better than her. ③“I bought this pair of shoes for my father，” Kate said. →Kate said she had bought that pair of shoes for her father. ④My father said，“I hope you will grow up to be President.” →My father said that he hoped I would grow up to be President. 三、时态的变化 1．直接引语变间接引语时句子时态变化如下表： 项目 直接引语 间接引语 句子 时态 一般现在时 一般过去时 现在进行时 过去进行时 现在完成时 过去完成时 一般过去时 过去完成时 过去完成时 过去完成时 一般将来时 过去将来时 ①His friend said to him，“We are planning to have a picnic.” →His friend told him that they were planning to have a picnic. ②The organizer said，“We have begun our plan.” →The organizer said that they had begun their plan. 2．直接引语变为间接引语，时态不发生变化的情况： (1)直接引语是客观真理、谚语和格言时； The teacher said, “The moon is much smaller than the sun.” →The teacher told them that the moon is much smaller than the sun.

Or maybe better put, another worldly landscape: the vast, and drying wetlands along the Great Salt Lake, the largest salt lake left in the western hemisphere (西半球), some fifty miles long and thirty wide. Carly Biedul is part of a team of scientists who have been tracking the lake's decline amid the West's record drought, which is made worse by climate change.They've been conducting weekly trips to various sampling and study sites for the last several years at the remote lake that only recently started making international headlines due to its sharp decline.Scientists warn the lake has already shrunk (缩减) nearly in half from its historical average.“For these birds that queue into these salty habitats, there are fewer places for them to go.” Says Heidi Hoven, a wetlands ecologist. Scientists say the West is believed to be as dry as it's been in 1，200 years.The record drought has been contributing to the Great Salt Lake's decline.But agriculture usually bears the major part of the blame.Upstream water diversion for expanding farms has meant less and less flows into the lake.Utah's population is also growing fast, and the development is now running right up to the lake. But all this shock and alarm, the scientists say, may be good.Faced with such severe situation, the state is being pushed into action.Utah Governor Spencer Cox has promised the lake won't dry up on his watch.The state's finance department has put upwards of a billion dollars lately into water conservation programs.Heidi Hoven sees the shorebirds as a key indicator species.“We have so much more to understand about what their needs are.In these changing times, it's really highlighting the need to understand these things quickly.The last two winters may have bought Utah a little time, but no one in the West is depending on another good snow year next year.” She says. [语篇解读]本文是一篇新闻报道。主要介绍的是犹他州盐湖干涸的相关情况。 1．What can we learn about the Great Salt Lake? A．It is the biggest salt lake in the world. B．It has been a worldwide focus for long. C．It is declining at an alarming rate. D．It attracts more and more birds. C　[细节理解题。根据第二段中的“They've been conducting weekly trips to various sampling and study sites for the last several years at the remote lake that only recently started making international headlines due to its sharp decline.Scientists warn the lake has already shrunk (缩减) nearly in half from its historical average.(在过去的几年里，他们每周都去这个偏远的湖泊进行各种采样和研究，直到最近，这个湖泊因其水位急剧下降才开始成为国际头条新闻。科学家警告说，该湖已经缩小了，比历史平均水平缩小了近一半。)”可知，这个湖泊的水位急剧下降，现在已经比历史水平缩小了近一半，由此可知，这个湖泊正以惊人的速度缩减。故选C项。] 2．What is the major cause of the lake's drying up? A．Water diversion. B．Climate change. C．Increasing population. D．Housing development. A　[细节理解题。根据第三段中的“The record drought has been contributing to the Great Salt Lake's decline.But agriculture usually bears the major part of the blame.Upstream water diversion for expanding farms has meant less and less flows into the lake.(创纪录的干旱导致了大盐湖的水量下降。但农业通常要承担主要责任。为扩大农场而进行的上游调水意味着流入湖中的水量越来越少。)”可知，农业对盐湖水量减少承担主要责任，为了扩大农场而进行的上游调水使得进入盐湖的水越来越少，由此可知，导流是造成盐湖干涸的主要原因。故选A项。] 3．What is Utah's reaction towards the drought? A．Its governor just made a false promise. B．It is determined to improve the situation. C．It asks scientists to keep watching. D．It spends lots of money to clear farms. B　[细节理解题。根据尾段中的 “Faced with such severe situation, the state is being pushed into action.Utah Governor Spencer Cox has promised the lake won't dry up on his watch.The state's finance department has put upwards of a billion dollars lately into water conservation programs.(面对如此严峻的形势，该州正被迫采取行动。犹他州州长斯宾塞·考克斯承诺，在他任期内，盐湖不会干涸。该州的财政部门最近在水资源保护项目上投入了超过10亿美元。)”可知，面对严峻形势，国家被迫采取行动，最近在水资源保护项目上投入了超过10亿美元，由此可知，面对干旱，犹他州决定改善当前的状况。故选B项。] 4．What is Heidi Hoven's attitude towards the drying Great Salt Lake? A．Optimistic. B．Uncaring. C．Relieved. D．Worried. D　[观点态度题。根据尾段中的“‘We have so much more to understand about what their needs are.In these changing times, it's really highlighting the need to understand these things quickly.The last two winters may have bought Utah a little time, but no one in the West is depending on another good snow year next year.’ She says.(‘我们对他们的需求还有很多需要了解。在这个瞬息万变的时代，它确实强调了快速理解这些事情的必要性。过去的两年可能给犹他州赢得了一点时间，但西部没有人指望明年会有一个好冬天。’她说。)”可知，Heidi Hoven认为，过去两年给犹他州赢得了一点时间，但西部没有人指望明年会有一个好冬天，由此可推断，Heidi Hoven对盐湖的干涸持担忧态度。故选D项。] B Fifty­four years ago, on April 22, 1970, twenty million Americans took to the streets to voice their concern about the deteriorating environment.The movement led to Earth Day. Unfortunately, our planet is in worse shape now than it was when Earth Day was first celebrated.The good news is that it's still not too late to reverse (转变) climate change if we all do our part.This Earth Day, take the first step towards helping our planet by participating in one of these fun activities. NASA is putting our planet up for adoption so you and your friend can claim a portion of the planet as your own.The space agency has divided the globe into 64，000 sections, each about 55 miles wide.All you have to do is type your name into NASA's “Adopt the Planet” site to claim a certificate that will give you the location of your slice of paradise (天堂) complete with details of its environment.NASA hopes that this exercise will stimulate interest and care in our planet. Search giant Google is also trying to engage the public with an updated Google Earth focused around Earth Day events.Through a new Voyager feature, users will be able to discover stories from around the world, learn about new places by reading“Knowledge Cards”and send postcards. If you happen to be anywhere near the nation's capital on April 22, join the millions that are expected to participate in the Earth Day March at the National Mall.The mission of the event that will feature guest speakers and musical performances is to mobilize (动员) citizens into taking action by promoting this year's Earth Day theme: climate and environmental science literacy. While participating in the above­mentioned activities is a great idea, it is just the beginning.All that is required are small lifestyle changes.Planting a tree or two, going meatless just one day a week, or switching your plastic water bottle for a reusable one will go a long way to help reverse the damage we have caused. [语篇解读]本文是说明文。文章介绍了一些庆祝“地球日”的有趣活动，号召人们从小事做起，采取行动保护环境。 5．The underlined word“deteriorating”is the closest in meaning to ． A．cleaner B．better C．worse D．colder C　[词义猜测题。根据第一段中“Fifty­four years ago, on April 22, 1970, twenty million Americans took to the streets to voice their concern about the deteriorating environment.(54年前的1970年4月22日，2 000万美国人走上街头，表达他们对环境的担忧)”及第二段中的“Unfortunately, our planet is in worse shape now than it was when Earth Day was first celebrated.(不幸的是，我们的星球现在的状况比第一次庆祝地球日时更糟)”可知，2000万美国人走上街头，表达他们对不断恶化的环境的担忧。由此推知，画线词deteriorating表示“恶化，变差”之意，与worse意思接近。故选C。] 6．If you participate in the activity of “Adopt the Planet”， you will be probably provided with your slice's, information about ． A．air quality B．ancient history C．local customs D．tourist attractions A　[推理判断题。根据第三段中“All you have to do is type your name into NASA's ‘Adopt the Planet’ site to claim a certificate that will give you the location of your slice of paradise (天堂) complete with details of its environment.(你所要做的就是在NASA的‘领养地球’网站上输入你的名字，就可以获得一张证书，上面会告诉你你所在的那片天堂的位置，以及它的环境细节)”可推知，如果你参加了“领养地球”活动，你可能会得到你所在区域的环境细节，包括空气质量。故选A。] 7．Through Voyager on Google Earth, what can users do? A．They can create “Knowledge Cards” online. B．They can discover stories from around the world. C．They can receive postcards coming from Google. D．They can adopt a slice of paradise in the world. B　[细节理解题。根据第四段中“Through a new Voyager feature, users will be able to discover stories from around the world, learn about new places by reading ‘Knowledge Cards’ and send postcards.(通过旅行者的新功能，用户将能够发现来自世界各地的故事，通过阅读‘知识卡片’了解新的地方，并发送明信片)”可知，通过谷歌Earth上的旅行者号，用户可以发现来自世界各地的故事。故选B。] 8．In the last paragraph, the writer calls on people to ． A．dream big B．fly high C．go meatless D．start small D　[推理判断题。根据最后一段“While participating in the above­mentioned activities is a great idea, it is just the beginning.All that is required are small lifestyle changes.(虽然参加上述活动是一个好的想法，但这只是开始。所需要的只是生活方式的小小改变)”可知，作者在此号召人们从现在开始行动起来，从小事做起。故选D。] Ⅱ.阅读七选五(每题2分，共10分) In this article, we want to present why nature conservation and the promotion of sustainable development principles are important. Environmental protection prevents natural disasters.Nature struggles for balance.This is how forests absorb CO2, grow and change it into oxygen.This provides an opportunity for life and also slows down climate change.The destruction of forests greatly changes the climate of entire regions, or even causes powerful floods.1. Environmental protection stimulates research and technological innovation.The idea for the first flying machine was inspired by bird observation.The rainforest is the richest source of many medicines.Almost every animal and plant has its own technical secrets.2. With the disappearance of ecosystems and wildlife species, the base for scientific research and technical improvement is nowhere to find. Protecting the environment is protecting people.The loss of natural resources leads to economic crises, wars or diseases.3. For example, the reduction of the population of bees will affect not only the production of honey, but also the whole food production system.No bees—no honey, no fruit, very few vegetables.This leads to hunger, disease, migration and war. 4． We meet with like­minded people.Any local success — the rescue of an endangered population for reserves — becomes a cause for global joy and inspires more participation. We humans are part of nature and its cycles ourselves.Our impact on ecosystems has noticeable influence on our daily lives.But it can be predicted and avoided if you think with your head and act carefully.5. Even small deeds can improve the state of nature and our life on the planet. A．People spy on them and copy. B．We are strongly dependent on it. C．Respect for ecosystems helps to avoid such troubles. D．And positive change can be promoted in the same way. E．Taking part in environmental protection is a source of joy. F．We consume the world's natural resources in our daily life. G．Even small changes in the ecosystem can cause huge disasters. [语篇解读]本文是说明文，主要介绍保护自然和促进可持续发展原则的一些理由。 1．C　[空前“The destruction of forests greatly changes the climate of entire regions, or even causes powerful floods.(森林的破坏极大地改变了整个地区的气候，甚至导致了强大的洪水。)”讲的是破坏森林会造成一些严重后果，C选项“Respect for ecosystems helps to avoid such troubles.(对生态系统的尊重有助于避免这些麻烦。)”提出尊重生态系统的必要性，其中的“avoid such troubles”承接前一句的内容，且是对本段的总结，呼应主题句，因此C选项符合语境，故选C。] 2．A　[本段主题句是“Environmental protection stimulates research and technological innovation.(环境保护激励研究和技术创新。)”，空前一句说“Almost every animal and plant has its own technical secrets.(几乎每一种动植物都有自己的技术秘密。)”，A项“People spy on them and copy.(人们监视他们，模仿他们。)”中的them指代前一句中的“technical secrets”，且指出人们通过对它们的技术秘密进行研究，应用于人类本身，呼应本段主题，因此A选项符合语境，故选A。] 3．G　[空处与前一句是递进关系，G项“Even small changes in the ecosystem can cause huge disasters.(即使是生态系统的微小变化也会造成巨大的灾难。)”与前一句动词都是“导致，造成”，都在说明一个现象造成了结果，其中的“Even small changes in the ecosystem”是对“The loss of natural resources”的更进一步说明，“cause huge disasters”呼应前一句的“economic crises, wars or diseases”，灾难的具体内容通过下文蜜蜂的例子加以具体说明，因此G选项承上启下，符合语境，故选G。] 4．E　[空处为本段落的主题句。由空格后的“We meet with like­minded people.Any local, success—the rescue of an endangered population for reserves—becomes a cause for global joy and inspires more participation.(我们会遇到志同道合的人。任何地方的成功——为保护区拯救濒危物种——都会成为全球的喜悦，并激发更多的参与。)”可知，本段主要讲的是参加保护环境的活动可以给人带来快乐，E选项“Taking part in environmental protection is a source of joy.(参与环保是一种快乐的源泉。)”说明参加环保活动可以给人带来快乐，因此E选项可作为本段主题句，故选E。] 5．D　[空后说“Even small deeds can improve the state of nature and our life on the planet.(即使是小小的行为也能改善自然状态和我们在这个星球上的生活。)”，说明我们的行为可以带来积极的变化，D选项“And positive change can be promoted in the same way.(积极的改变也能以同样的方式被促进。)”中的“positive change”即是下文的“improve the state of nature and our life on the planet”，且说明了我们的行为能带来的积极变化，因此D选项承上启下，符合语境，故选D。] Ⅲ.语法填空(每题2分，共20分) Reduce your energy costs and do something good for the environment with novel solar solutions at Lowe's.Solar power offers an endless supply of energy 1. can power your home, and you can make use of it by 2.
