专题限时训练(二十二)史地自然型阅读理解(限时：25分钟)(一)The Pacific island nation of Nauru used to be a beautiful place.Now it is an ecological disaster area.Naurus heartbreaking story could have one good consequenceother countries might learn from its mistakes.For thousands of years，Polynesian people lived in the remote island of Nauru，far from western civilization.The first European to arrive was John Fearn in 1798.He was the British captain of the Hunter, a whaling ship.He called the island Pleasant Island.However, because it was very remote, Nauru had little communication with Europeans at first.The whaling ships and other traders began to visit，bringing guns and alcohol.These elements destroyed the social balance of the twelve family groups on the island.A tenyear civil war started，which reduced the population from 1，400 to 900.Naurus real troubles began in 1899 when a British mining company discovered phosphate(磷酸盐)on the island.In fact，it found that the island of Nauru was nearly all phosphate，which was a very important fertilizer for farming.The company began mining the phosphate.A phosphate mine was not a hole in the ground；it was a strip mine.When a company stripmined，it removed the top layer of soil.Then it took away the material it wanted.Strip mining totally destroyed the land.Gradually, the lovely island of Nauru started to look like the moon.In 1968，Nauru became one of the richest countries in the world.Every year the government received millions and millions of dollars for its phosphate.Unfortunately, the leaders invested the money unwisely and lost millions of dollars.In addition，they used millions more dollars for personal expenses.Soon people realized that they had a terrible problemtheir phosphate was running out.Ninety percent of their island was destroyed and they had nothing.By 2000，Nauru was financially ruined.Experts say that it would take approximately$433，600，000 and more than 20 years to repair the island.This will probably never happen.1What might be the authors purpose in writing the text?ATo seek help for Naurus problems.BTo give a warning to other countries.CTo show the importance of money.DTo tell a heartbreaking story of a war.2What was Nauru like before the Europeans came?ARich and powerful.BModern and open.CPeaceful and attractive.DGreedy and aggressive.3The ecological disaster in Nauru resulted from_Asoil pollutionBphosphate overminingCfarming activityDwhale hunting4Which of the following was a cause of Naurus financial problem?AIts leaders misused the money.BIt spent too much repairing the island.CIts phosphate mining cost much money.DIt lost millions of dollars in the civil war.5What can we learn about Nauru from the last paragraph?AThe ecological damage is difficult to repair.BThe leaders will take the experts words seriously.CThe island was abandoned by the Nauruans.DThe phosphate mines were destroyed.(二)If you are afraid of the dark，its not a big deal.Its perfectly normal to feel afraid. After all，animals do，too. “Fear matters，”says Karen Warkentin，an ecologist.“Its a good thing，” she adds, “because fear makes you do things that keep you alive.”Like kids，many animals experience fear and they respond to the feeling in variety of ways.A frightened turtle pulls its head and legs inside its shell.A small fish will swim away when a big，hungry fish approaches.Some animals respond to fear in ways you might not expect.The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying redeyed tree frogs in Costa Rica.In this species，female frogs attach jellylike clumps(果冻一样的块状物)of their eggs to the undersides of leaves.The leaves hang on branches that dangle(悬挂)over ponds.After they hatch from the eggs，the tadpoles(蝌蚪)then fall into the water，where they eventually grow into adult frogs.Tree frog eggs usually grow for 6 days before hatching.If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of the schedule. As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.If hatching early helps protect redeyed tree frogs from snakes，you might wonder why their eggs dont always hatch sooner.It turns out that hatching early brings its own danger.Once tadpoles land in the water，hungry fish and other animals like to eat them, too.Staying in their eggs for 6 days，then，allows frog embryos(胚胎)to grow big and strong.This extra growth improves their chances of surviving in the water.1It can be inferred from the passage that fears_Ahelp animals grow bigger and strongerBare less common among young animalsChelp animals move a lot to fit the environmentDare more or less important for animals to survive2We are told in the passage that tree frogs_Aface danger both inside their eggs and in the waterBwill grow fast if they fall into the water laterCare surprisingly clever when inside their eggsDstay in their eggs longer if they are frightened3Why do the tadpoles hatch up to 2 days ahead of the schedule？Because_Athey like falling into the water earlyBthey want to grow into adult frogsCthey sense a hungry snake is about to attackDfrog embryos can grow strong4What is the best title of the passage?AWhat is fear?BWhy do we feel afraid?CYou feel afraid；animals do, tooDFear is a good thing5What would be discussed in the following paragraph?AFurther explanations as to why tree frogs hatch ahead of the schedule.BHow the unborn frogs know when a snake is about to attack them.CAnother example of animals that respond to fear in an unexpected way.DHow tree frogs improve their chances of survival before falling into the water.(三)Besides containing attractive flowers, trees and other plants that beautify the community, ecofriendly rain gardens(雨水花园) are healthy for the environment and the people living and working nearby. A rain garden is not very different from a traditional garden. It is just a far more ecofriendly garden. Usually it is built lower than the ground. Rain gardens make smart use of rain and storm water by temporarily holding water from rain and storms and letting it soak(浸入)slowly into the ground before it runs into streams or enters the public drinking water supply.Thus, a rain garden keeps the water, allowing it to be used as needed by plants in the rain garden, rather than flowing immediately into nearby streams and going unused. The water will soak slowly into the ground within a day or two. This creates an advantage that the rain garden does not allow mosquitoes to breed. This is a simple, attractive, and ecofriendly “green” way to treat storm water.Whats more, planting a rain garden helps reduce pollution and improve the environment. Without using expensive machinery and chemicals, rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%.Native plants are recommended for rain gardens because they are more used to the local climate, soil, and water conditions. They may attract local wildlife such as native birds. Water your rain garden immediately after planting and once a week, unless you have had at least an inch of rain during the week. Once the native plants establish the necessary root system, it will require little care.Often, local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems. However, you dont need to be a professional environmental engineer to create a rain garden. As long as youre ecoconscious homeowners, you can help the environment by building smaller rain gardens in your yards.1Which of the following is NOT true for the function of rain gardens?A. They are good for living conditions. B. They increase pollution.C. They can beautify the community. D. They improve the environment.2Which of the following is the ecofriendly function of rain gardens discussed in Paragraph 4?A. They can keep the rain and storm water. B. They can help reduce the pollution problem.C. They can be healthy for the people around. D. They can make the environment more beautiful.3One of the main reasons why native plants are recommended is that _.A. they cost less and are much easier to get B. they may attract local wildlife to comeC. they require little care from the local gardener D. they are more used to the local growing conditions4What do we know about rain gardens?A. They need little water after all the plants are planted.B. They usually need at least an inch of rainwater a week.CThey may attract local birds and change the local climate.D. They may reduce the water pollution problem by 70%.5. Who are the intended readers of the passage?A. Homeowners. B. Students. C. Engineers. D. Educators.专题限时训练(二十二)(一)【要点综述】 文章主要讲述了太平洋岛国瑙鲁如何从一个环境优美的天堂岛变成一个生态失衡、满目疮痍的小岛。1B 写作意图题。由文章第一段的“Now it is an ecological disaster area.Naurus heartbreaking story could have one good consequenceother countries might learn from its mistakes.”可以看出，作者的目的是给当前很多只注重发展经济而忽略环境保护的国家一个警告。故选B项。2. C细节理解题。从第一段提到的“太平洋上的国家瑙鲁岛曾经是一个美丽的地方”看出，瑙鲁岛是attractive；由第二段第一句以及第三段第一句可知，上千年来，瑙鲁岛的人们生活在偏远的小岛上，过着平静的生活。故选C项。3B 细节理解题。由最后一段的“Soon people realized that they had a terrible problemtheir phosphate was running out.Ninety percent of their island was destroyed and they had nothing.”可以得知“磷酸盐逐渐减少，开采殆尽”。由此可以看出，“磷酸盐的过量开采”导致了生态灾难。故选B项。4A 细节理解题。由最后一段的“Unfortunately，the leaders invested the money unwisely and lost millions of dollars.In addition，they used millions more dollars for personal expenses.”看出，是领导人不正确使用资金导致了财政问题。故选A项。5A 推理判断题。文章最后告诉我们：Experts say that it would take approximately $433，600，000 and more than 20 years to repair the island.也就是说，瑙鲁岛上的生态损失弥补起来需要大量的资金和时间，即选项所说的“修复起来很难”。故选A项。(二)【要点综述】 本文主要论述的是恐惧是人类和动物常见的一种现象，有时恐惧是一件好事。动物对于恐惧的反应是不同的，有些反应方式甚至超乎人们的想象。1D推理判断题。根据“because fear makes you do things that keep you alive.”可知D项正确。2A细节理解题。根据“If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of the schedule.”和“Once tadpoles land in the water，hungry fish and other animals like to eat them，too.”可知，它们在孵化期间害怕蛇的攻击，在水里害怕被其他动物吃掉。故选A项。3C细节理解题。根据“If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of the schedule.As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.”可知，因为对它们有威胁的蛇不会游泳，所以提前孵化出来，掉到水里，蝌蚪就能够逃离蛇的攻击了。故选C项。4D主旨大意题。文章通过举例说明害怕是一件好事。故选D项。5C篇章结构题。根据“Some animals respond to fear in ways you might not expect.The first example is that the fear of being eaten can scare some frogs right out of their eggs.”可知，既然这是举例，有了第一个例子，那么它的后面还会有例子。故选C项。(三)【要点综述】 本文主要介绍了环境友好型的雨水花园是如何运作的。1B细节理解题。由第四段第一句“Whats more, planting a rain garden helps reduce pollution and improve the environment.”可知，雨水花园不会增加污染，故B项有误。由第一段“Besides containing attractive flowers, trees and other plants that beautify the community, ecofriendly rain gardens(雨水花园) are healthy for the environment and the people living and working nearby.”可知，雨水花园可以美化社区、改善环境以及对居住环境有益，为环境友好型花园，故A、C、D三项正确。2B细节理解题。由第四段第一句“Whats more, planting a rain garden helps reduce pollution and improve the environment.”可知，雨水花园可以帮助减少污染。3D细节理解题。由第五段第一、二句“Native plants are recommended for rain gardens because they are more used to the local climate, soil, and water conditions.”可知，建议种本地的植物是因为本地的植物更适应本地的环境。4B细节理解题。由第五段第三句“Water your rain garden immediately after planting and once a week, unless you have had at least an inch of rain during the week.”可知，雨水花园需要一个星期一英寸的雨水。5A推理判断题。由本文最后一句“As long as youre ecoconscious homeowners, you can help the environment by building smaller rain gardens in your yards.”可知本文主要是写给房主的。
