课时作业(五) [限时30分钟] Ⅰ.阅读理解 A Some people say that the planet is getting smaller, that there are few places left to explore, and that the age of exploration will be over soon. I would argue instead that there has never been a greater need to explore. That's because the stage for all exploration is the natural world, and nature is experiencing a rapid decline. It is by exploring that we understand and when we understand we develop an appreciation for what is found. Ultimately, only the things we appreciate are worth protecting. As the golden age of exploration weakens, so does the richness of life on Earth. It isn't just that there are fewer blank areas on the map; it is that wild places and spaces have been progressively carved up (瓜分). Visiting the Okavango Delta or Kalahari Desert, for example, no longer implies a selfsupported expedition. Field stations pop up in important national parks and remote sensing by satellite becomes commonplace. In the next century, I believe we will need larger and wilder areas. We will need the wilderness, not just for the protection of it, but because it is an important part of the ecosystems from which we gain our necessities like clean water, food and materials. If we succeed, then expeditions —brief travels into the wild that seek to answer questions, monitor populations, and inspire action—will have a renewed sense of purpose. More importantly, they greatly help the public experience, understand and appreciate nature. Based on my own research expedition which aims to understand “edge effects” — how the changes in temperature at forest edges impact animals, I find it important that today's scientists continue to spend time in the field. It is here that they begin to understand how seemingly unrelated environmental interactions influence their study system. Sometimes, it's difficult to know which is important to measure until you stand out there on the forest edge. It is the young generation that is the main force to lead the next wave of expeditions. The measure of their success will be whether there are still wellpreserved wild places for expeditions in the future. Their leadership is needed now, more than ever. [语篇解读]　本文是一篇说明文。文章主要介绍了科学家实地探索来了解自然的重要性。通过探索，人们才能理解并欣赏值得保护的东西。 1．What's the purpose of this text? A.To suggest understanding nature by keeping exploring. B.To advise people not to travel to unknown places. C.To inform us about the reduced biodiversity. D.To call on the public to support the study. A　推理判断题。通读全文，尤其是第二段“I would argue instead that there has never been a greater need to explore. ..., only the things we appreciate are worth protecting.(相反，我想说的是，从未有过更大的探索需求。这是因为所有探索的舞台都是自然界，而自然界正在经历迅速的衰退。正是通过探索，我们理解了，当我们理解了，我们就会对所发现的东西产生欣赏。最终，只有我们欣赏的东西才值得保护。)”和第四段“If we succeed, then expeditions ..., they greatly help the public experience, understand and appreciate nature.(如果我们成功了，那么探险队——短暂的野外旅行，寻求回答问题、监测种群并激励行动——将有新的目标感。更重要的是，它们极大地帮助公众体验、理解和欣赏自然。)”可推知，文章的写作目的是建议通过不断探索来了解自然。故选A。 2．What can we know about the expedition in wild spaces from Paragraph 3? A．It is difficult for explorers to make progress. B．It is more accessible with the help of technology. C．It promotes the development of satellite technology. D．It requires explorers to take sufficient heavy equipment. B　推理判断题。根据第三段中“Visiting the Okavango Delta or Kalahari Desert，...and remote sensing by satellite becomes commonplace.(例如，访问奥卡万戈三角洲或卡拉哈里沙漠，就不再意味着自力更生的探险。在重要的国家公园里都会出现野外观测站，利用卫星进行遥感也会变得很普遍。)”可推知，在技术的帮助下，野外探险更加容易到达，故选B。 3．What does the underlined part “pop up” in Paragraph 3 probably mean? A．Appear unexpectedly. B．Close temporarily. C．Develop quickly. D．Differ greatly. A　词句猜测题。划线词组上文讲到“Visiting the Okavango Delta or Kalahari Desert, for example, no longer implies a selfsupported expedition. (例如，参观奥卡万戈三角洲或卡拉哈里沙漠，不再意味着自力更生的探险。)”可知，野外探险不再是自力更生的探险，因此推断划线词组所在句子“Field stations pop up in important national parks and remote sensing by satellite becomes commonplace.”的意思是：在重要的国家公园里出现了野外观测站，卫星遥感变得司空见惯。说明在在技术的帮助下，野外探险容易了，可知第三段中带下划线的部分的意思是“突然出现”，故选A。 4．What does the author realize after his research expedition? A．The significance of scientists' field trip. B．The difficulty of carrying out fieldwork. C.The need to expand the edges of forests. D.The influence of his study on the environment. A　推理判断题。根据倒数第二段“Based on my own research expedition which ... until you stand out there on the forest edge.(根据我自己的研究考察，目的是了解“边缘效应”——森林边缘温度的变化如何影响动物，我发现今天的科学家继续花时间在这个领域是很重要的。正是在这里，他们开始理解看似无关的环境相互作用如何影响他们的学习系统。有时候，在你站在森林边缘之前，很难知道哪个是重要的测量值。)”可推知，作者在研究探险之后意识到了科学家实地考察的意义。故选A。 B About 97% of the world's water is salty and is found in our oceans and seas.But，as we can't drink sea water，how can it be important? Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths.Most of the different species of animals and fish depend on simple plants for their food.These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen.In fact，the algae produce over half of the oxygen people breathe.How important sea water is! Each plant or animal in our seas and oceans is an important link in a food chain.The algae are eaten in large amounts by microscopic animals，which are in turn consumed by larger animals.These food chains are delicately balanced. The bad news about the food chains in the oceans is that they are under threat because of man.People once thought that the oceans were so big that it didn't matter if we dumped rubbish into them or caught huge quantities of fish and whales for food.But we now know this is not true and fish stocks in the oceans have started to drop. Thankfully，the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats.Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution.Finally，the importance of protecting oceans is being made known to more people.This is just the beginning of a long process to protect the oceans for our future.We depend on the oceans for fish which are an important part of the human diet.How important sea water is! [语篇解读]　海洋对人类的生存起到至关重要的作用，但是人类在很长一段时间内对海洋造成了污染和破坏，现在各国都在努力采取措施保护海洋。 5．Which of the following is the proper order of the food chain? A.small animals→algae→microscopic animals→large animals→man B.algae→microscopic animals→large animals→larger animals→man C.small animals→algae→large animals→microscopic animals→man D.microscopic animals→algae→large animals→larger animals→man B　细节理解题。根据第三段内容可知，微生物吃海藻，然后逐次地大一点的动物吃小一点的动物，最后被人吃掉。故选B。 6．People used to think that the rubbish thrown into the sea ． A．wouldn't harm the fish in the sea B．would change the balance of the food chain　 C．would be broken down in the sea D．wouldn't do much harm to the sea D　细节理解题。根据第四段第二句可知，过去人类认为将垃圾倒入大海不会对大海造成破坏。 7．From the passage，we learn that ． A．most fish and sea animals live at the surface of the seas B．it is very difficult to break the balance of a food chain C．excessive fishing has caused the decrease in fish stocks D．it won't be long before the problems concerning oceans will be solved C　推理判断题。根据第四段最后两句可知，现在人类已经认识到原来的做法是不正确的，而且鱼的储存量开始下降，可知过度的捕捞造成了这一结果。 8．Which of the following is NOT a way being used to protect oceans? A．The use of international agreements. B．Forbidding fishing to protect fish stocks. C．The use of new techniques. D．Raising people's awareness of the need to protect oceans. B　细节理解题。根据最后一段第二句可知，很多国家限制鱼类的捕捞，而不是禁止，故B项不正确。 Ⅱ.七选五 Urban Wildlife Cities are diverse ecosystems. In addition to visitors, a large number of species share our urban areas. As our cities spread, we need to think about what it is like for other species to have human neighbors. Cities are built for humans. 1 For example, most city parks are kept neat and tidy so that humans will find them beautiful. But when we cut grass or plants, we destroy natural habitats, which leads to the imbalance of ecology. 2 When a bridge in Austin, Texas was repaired, engineers added small gaps running the length of its bottom. This made a good home for bats, and soon the bridge was home to thousands of bats. 3 Now, they have come to value their winged neighbors. The bats become an attraction, and they eat lots of bugs every night. There are also structures built with the aim of bringing wildlife into the city. The Olympic Forest Park in Beijing is a good example. The park used native plants, and created open and natural spaces for wildlife. The result is a zone in Beijing with over 160 species of birds. In many ways, the park is the opposite of a zoo. 4 If we learn to share our space, we can become better neighbors of the wildlife around us. 5 Our own future will be endangered too. A．They are built to protect birds. B．Our actions sometimes help other species. C．If we do not, more species will become extinct. D.They do not always provide suitable habitats for wildlife. E．Instead of being kept in cages, wildlife can move more freely. F．At first, people were afraid of the bats and tried to get rid of them. G．They would sit on it and their droppings would fall into the water. [语篇解读]　本文是一篇说明文。在城市中人类应该考虑为野生动物提供和分享空间。 1．D　由空格后的例子“For example, most city parks are kept neat and tidy..., which leads to the imbalance of ecology.(例如，大多数城市公园保持整洁，这样人们就会发现它们很漂亮。但是当我们割草或植物时，我们破坏了自然栖息地，这导致了生态的不平衡)”可知，空格处的句子应该涉及到对野生动物栖息地的破坏。所以D项(它们并不总是为野生动物提供合适的栖息地)填入空格处，符合题意。故选D项。 2．B　空格后的例子“When a bridge in Austin，Texas was repaired，..., and soon the bridge was home to thousands of bats.(当德克萨斯州奥斯汀市的一座桥被修复时，工程师们在桥的底部增加了一些小裂缝。这为蝙蝠提供了一个很好的栖息地，很快这座桥就成了成千上万只蝙蝠的家)”说明人类的行为对野生动物的帮助，这一例子肯定是为了证明空格处的句子，所以空格处的句子一定和人类帮助野生动物有关。所以B项(我们的行为有时会帮助其他物种)填入空格处，符合题意。故选B项。 3．F　空格后的句子“Now, they have come to value their winged neighbors.(现在，它们开始重视它们长翅膀的邻居)”是说人们现在对待这些蝙蝠的态度。空格处的句子应该提到人们原来对待这些蝙蝠的态度，形成前后的对比。所以F项(起初，人们害怕蝙蝠，试图除掉它们)填入空格处，符合题意。故选F项。 4．E　空格前的句子“In many ways, the park is the opposite of a zoo.(在许多方面，这个公园和动物园是对立的)”是说这个公园和动物园是对立的。为什么这样说呢？E项(野生动物不再被关在笼子里，它们可以更自由地活动)给出了答案：。应该E项填入空格处，和上文是顺接关系，符合题意。故选E项。 5．C　根据空格后的句子“Our own future will be endangered too.(我们自己的未来也将受到威胁)”可知，空格处的句子一定提到野生动物的危险处境。所以C项(如果我们不这样做，更多的物种将会灭绝)填入空格处，符合题意。故选C项。 Ⅲ.语法填空 In 1916 the United States started the world's first national park system. Since then, it 1 (serve) as a model for other countries that try to better protect the environment and let people enjoy nature. A national park is a reserve of land 2 (declare) and owned by the government, protected from human development and pollution. Now China is planning its own national park system. On Dec 5, China passed two pilot plans for national parks 3 (protect) the giant panda, Siberian tiger and Amur leopard. Before this national park project, China had set aside thousands of nature parks, forests and scenic areas 4 protected areas. However, they haven't been managed well because too many different 5 (organization) have been involved in the protection of the different areas, according to the China Daily. Under 6 new plans, national parks will cover big areas and include different protected areas. For example, the habitats of wild pandas lie in different provinces and 7 (cut) into even smaller pieces by railways, roads and power lines. This makes panda groups 8 (open) to danger. The panda national park will cover all the habitats and make the protection of animals as comprehensive as possible. 9 this increased protection doesn't mean national parks will shut their doors to humans. Instead, the new system will offer people a chance to 10 (deep) feel nature. [语篇解读]　本文是一篇应用文。介绍中国建国家公园的过程以及重要意义。 1．has been serving/has served　考查谓语动词。句意：从那时起，它就成为其他国家更好地保护环境，让人们享受自然的典范。分析句子成分可知，空处应为谓语动词。照应时间状语“Since then”以及主语“it”可知，应为现在完成时，且用单数。结合句意，美国国家公园一直是典范，也可以用现在完成进行时。故填has been serving/has served。 2．declared　考查非谓语动词。句意：国家公园是由政府宣布并拥有的保护区，不受人类开发和污染的影响。分析句子成分可知，空处应为非谓语动词。且提示词和被修饰词“a reserve of land”之间为动宾关系，故用过去分词形式作定语。故填declared。 3．to protect　考查非谓语动词。句意：12月5日，中国通过了两项国家公园试点计划，以保护大熊猫、东北虎和东北豹。分析句子成分可知，空处应为非谓语动词。且应为不定式做目的状语。故填to protect。 4．as　考查介词。句意：在这个国家公园项目之前，中国已经划出了数千个自然公园、森林和风景名胜区作为保护区。分析句子成分可知，空处应为介词。结合句意，“自然公园、森林和风景名胜区”是作为“保护区”使用的。故填as。 5．organizations　考查名词。句意：然而，据《中国日报》报道，由于太多不同的组织参与了不同地区的保护，它们并没有得到很好的管理。根据空前形容词“different”可知，应为名词复数。故填organizations。 6．the　考查冠词。句意：根据新的计划，国家公园将覆盖大片区域，并包括不同的保护区。根据句意，应为定冠词表示特指。故填the。 7．are cut　考查谓语动词。句意：例如，野生大熊猫的栖息地分布在不同的省份，被铁路、公路和电线切割成更小的碎片。分析句子成分可知，空处应为谓语动词。照应主语“the habitats”以及并列谓语动词“lie”的时态可知，应为被动语态，为复数，文章主时态一般现在时。故填are cut。 8．more open　考查形容词。句意：这使得熊猫群体更容易面临危险。根据前文“野生大熊猫的栖息地分布在不同的省份，被铁路、公路和电线切割成更小的碎片”可知，这种情况会让熊猫的处境比之前更危险。故应为形容词的比较级。故填more open。 9．But　考查连词。句意：但加强保护并不意味着国家公园将对人类关闭大门。根据前文“熊猫国家公园将覆盖所有的栖息地，使动物的保护尽可能全面。”以及本句“加强保护并不意味着国家公园将对人类关闭大门”可知，前后为转折含义。故填But。 10．deeply　考查副词。句意：相反，新系统将为人们提供一个深入感受自然的机会。应为副词修饰动词“feel”。故填deeply。 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
