But we change our planet all the time. We do many good things, but we do more bad things. Water pollution A lot of people, birds and fish die each day because of water pollution. Factories are polluting the water. Many rivers and lakes are now very dirty. Air pollution In big cities, factories, cars and buses are the main causes (原因) of air pollution. Many people in cities now have health problems. For example, Mexico City was a beautiful sunny capital in the past, but today it is always covered by thick brown clouds. Soil (土壤) pollution In order to have a good harvest, most of the farmers use chemicals too much in their fields. That’s bad for the soil. But this kind of pollution is difficult to stop. Hope for the future These problems are very serious (严重的) for our future, so all of us should do something to improve our environment. If we can stop pollution, our planet will become more and more beautiful and our health will be better. Let’s be greener people! 1．How many kinds of pollution are mentioned (提及) in the text? A．Two.

With the development of the world, people are paying more attention to the environment. Aviation is one of the industries that cause pollution. So, making aviation greener is necessary.​ One way to make aviation greener is to use new fuels (燃料). Scientists are working hard to find new fuels that are cleaner than the traditional ones. For example, some airlines are starting to use biofuels (生物燃料). These fuels are made from plants. They can reduce a lot of pollution.​ Another way is to improve the design of airplanes. New-designed airplanes are more aerodynamic (空气动力学的). They can fly more efficiently (高效地), using less fuel. This also helps to reduce pollution.​ Moreover, airlines can also manage their flights better. By planning the flight routes carefully, airplanes can avoid unnecessary detours (绕行), saving fuel and reducing emissions (排放).​ Green aviation is good for the environment and the future of our planet.

Plants, animals, and many other living things work together to keep our Earth healthy and happy. In hot deserts, we find special (特殊的) plants called cactuses. They have big stems to keep water, so they can live with little rain. Cactuses have spines to stop animals from getting to them. They look different in many ways, some are small and others big. Plants give us oxygen and food. If there are no plants, we can’t live. Animals are important too. They help plants grow by moving a kind of powder (粉末) from one flower to another. We call this “pollination”. People also live in deserts. They build houses to stay cool. These houses have special ways to keep the hot sun out and let in fresh air. They do not use much water and are friendly to the desert world. We should love and look after all the living things in nature. When we do this, we help keep our Earth clean and safe. Let’s be friends with nature and take care of Mother Nature. 1．What do plants, animals, and other living things do for our Earth? A．They make it bad. B．They keep it open all year long.

Far away in the mountains, there was a small village, and a young woman named Annie lived there with her parents. The village was close to a river, and the villagers got their water from there. However, things suddenly changed one summer. There was very little rain, and the water levels in the river fell. Annie got very worried. Would all the water in the river disappear?

Joel Sartore, a photographer and environmentalist, has made a point of planting native (本地的) wildflowers at home and at his office. He also encourages his neighbours to start their own gardens of native plants. Why? Wildflowers need our help. In the U.S., Great Plains alone, over 33 million acres of wildflowers and grasslands have been lost since 2009, according to WWF. You’ve probably heard that wildflowers support insects like butterflies and bees, which play a huge role in pollinating crops (庄稼授粉) that we depend on for food. That’s just one of many ways wildflowers and other native plants are important to our earth. Native flowers are part of a living network. They lock carbon (碳) within soil, an important part of mitigating (减缓) changes in weather. They store water and nutrients, which are good for forests. And, of course, they look beautiful, making them an attraction in any place. “If we hope to encourage children to grow up fighting to save the planet, wildflowers are a perfect fit; they get kids thinking about nature with a sense of wonder,” Sartore says. “These places serve as outdoor classrooms, plus they clean our air, soil, and water.” But what can we do? You don’t have to be an eager gardener or have lots of land to put your effort into. If you live in a city, you can just plant flowers in a window box or on your rooftop. Another way to get involved beyond your own space at home is to find out how public green spaces near you are managed. You can also volunteer at a local nature center or community garden that is planting native plants. If you aren’t sure what types of plants are native to your area, ask at a nearby garden center or search online. “I believe that people want to help make the planet a better place, but they just don’t know where to start,” Sartore says. “Planting wildflowers and other plants is a great way.” 1．Why does Sartore plant wildflowers at home and at his office? A．To show what types of plants are native to the area. B．To encourage his neighbours to plant more native plants. C．To provide kids with some places as outdoor classrooms. D．To call attention to the disappearance of native wildflowers. 2．What’s Paragraph 3 mainly about? A．The power of wildflowers. B．The ways of planting flowers. C．The benefits of insects like bees. D．The importance of the living network. 3．According to the passage, what might be the proper way to help with native wildflowers? A．Building a big garden near your community. B．Working as volunteers to help in local parks. C．Encouraging yourself to be an eager gardener first. D．Moving from the city to the village to grow plants. Some places in nature hold so much water that the ground there is almost always wet. These special places are called wetlands. The Everglades is an area of beautiful wetlands in southern Florida. Many kinds of waterbirds, such as wood storks, and mammals, such as bobcats, live in the Everglades. A number of reptiles live there, too. In fact, southern Florida is one of the few places in the world where alligators and crocodiles live side by side. The Everglades area is an ecosystem. Ecosystems are places where living things exist (存在) with nonliving things, such as water and soil. Everything in an ecosystem affects everything else. If something new is brought into the ecosystem, it may cause problems. Change caused by humans brought big problems in the Everglades. As more people moved to Florida, new homes and businesses were needed. Because the Everglades area was large and beautiful, people thought it might be a good place to build. The ground, however, was too wet. In order to build homes, people drained water from some of the wet ground. Taking water out of the Everglades caused many problems. Animals that ate water plants or small fish had a hard time finding food. The wood stork and other waterbirds began dying. People worried that this special place would be lost forever. Today, a portion of the Everglades is a national park. The law protects animals and plants there. Homes and businesses cannot be built inside Everglades National Park. Because it is now protected as a park, part of the Everglades will be beautiful wetlands for many years to come. 1．What is special about the Everglades? A．It is an area of wetlands. B．It is in a desert. C．It has only trees. D．It is a city in Florida. 2．According to the passage, what can we know about an ecosystem? A．All ecosystems are exactly the same. B．It can only survive with human help. C．Changes in one part affect the whole system. D．Plants are more important than animals there. 3．The underlined word “drained” in Paragraph 4 means ________. A．gave out B．looked for C．used up D．took away 4．How is the Everglades protected today? A．By developing business. B．By making it a national park. C．By closing down to all visitors. D．By allowing people to build homes. 学科网（北京）股份有限公司 $ Unit 4 The Earth 单元话题阅读理解练习 Unit 4 The Earth单元话题：环保 本资料共10篇专题训练，从上到下依次按照难度分为基础语篇巩固练和重难语篇提升练 基础语篇巩固练 It’s Sunday morning and the weather is nice.

Plants, animals, and many other living things work together to keep our Earth healthy and happy. In hot deserts, we find special (特殊的) plants called cactuses. They have big stems to keep water, so they can live with little rain. Cactuses have spines to stop animals from getting to them. They look different in many ways, some are small and others big. Plants give us oxygen and food. If there are no plants, we can’t live. Animals are important too. They help plants grow by moving a kind of powder (粉末) from one flower to another. We call this “pollination”. People also live in deserts. They build houses to stay cool. These houses have special ways to keep the hot sun out and let in fresh air. They do not use much water and are friendly to the desert world. We should love and look after all the living things in nature. When we do this, we help keep our Earth clean and safe. Let’s be friends with nature and take care of Mother Nature. 1．What do plants, animals, and other living things do for our Earth? A．They make it bad. B．They keep it open all year long.

Joel Sartore, a photographer and environmentalist, has made a point of planting native (本地的) wildflowers at home and at his office. He also encourages his neighbours to start their own gardens of native plants. Why? Wildflowers need our help. In the U.S., Great Plains alone, over 33 million acres of wildflowers and grasslands have been lost since 2009, according to WWF. You’ve probably heard that wildflowers support insects like butterflies and bees, which play a huge role in pollinating crops (庄稼授粉) that we depend on for food. That’s just one of many ways wildflowers and other native plants are important to our earth. Native flowers are part of a living network. They lock carbon (碳) within soil, an important part of mitigating (减缓) changes in weather. They store water and nutrients, which are good for forests. And, of course, they look beautiful, making them an attraction in any place. “If we hope to encourage children to grow up fighting to save the planet, wildflowers are a perfect fit; they get kids thinking about nature with a sense of wonder,” Sartore says. “These places serve as outdoor classrooms, plus they clean our air, soil, and water.” But what can we do? You don’t have to be an eager gardener or have lots of land to put your effort into. If you live in a city, you can just plant flowers in a window box or on your rooftop. Another way to get involved beyond your own space at home is to find out how public green spaces near you are managed. You can also volunteer at a local nature center or community garden that is planting native plants. If you aren’t sure what types of plants are native to your area, ask at a nearby garden center or search online. “I believe that people want to help make the planet a better place, but they just don’t know where to start,” Sartore says. “Planting wildflowers and other plants is a great way.” 1．Why does Sartore plant wildflowers at home and at his office? A．To show what types of plants are native to the area. B．To encourage his neighbours to plant more native plants. C．To provide kids with some places as outdoor classrooms. D．To call attention to the disappearance of native wildflowers. 2．What’s Paragraph 3 mainly about? A．The power of wildflowers. B．The ways of planting flowers. C．The benefits of insects like bees. D．The importance of the living network. 3．According to the passage, what might be the proper way to help with native wildflowers? A．Building a big garden near your community. B．Working as volunteers to help in local parks. C．Encouraging yourself to be an eager gardener first. D．Moving from the city to the village to grow plants. 【答案】1．D 2．A 3．B 【导语】本文是一篇说明文。文章主要讲述了Joel Sartore呼吁大家种植野花保护地球的事情。 1．推理判断题。根据“Wildflowers need our help. In the U.S., Great Plains alone, over 33 million acres of wildflowers and grasslands have been lost since 2009, according to WWF.”可知，自2009年以来，仅在美国大平原地区，就有超过3300万英亩的野花和草原被毁。所以推断出Joel Sartore在家和办公室种植野花是为了引起大家对于本土野花消失的关注，故选D。 2．主旨大意题。通读第三段可知，野花在为我们赖以生存的作物授粉方面发挥着巨大作用；它们将碳锁定在土壤中，这是缓解天气变化的重要组成部分；它们储存水和营养物质，对森林有好处；它们看起来很漂亮，在任何地方都很吸引人。所以本段主要讲了野花的作用，选项A“野花的力量”符合题意，故选A。 3．细节理解题。根据“If you live in a city, you can just plant flowers in a window box or on your rooftop.”和“Another way to get involved beyond your own space at home is to find out how public green spaces near you are managed. You can also volunteer at a local nature center, or community garden that is planting native plants.”可知，为了保护野花可以做的有：如果你住在城市里，你可以在窗台或屋顶上种花，另一种在家里自己的空间之外参与的方法是了解你附近的公共绿地是如何管理的。你也可以在当地的自然中心或种植本土植物的社区花园做志愿者。选项B“作为志愿者在当地公园提供帮助。”符合题意，故选B。 Some places in nature hold so much water that the ground there is almost always wet. These special places are called wetlands. The Everglades is an area of beautiful wetlands in southern Florida. Many kinds of waterbirds, such as wood storks, and mammals, such as bobcats, live in the Everglades. A number of reptiles live there, too. In fact, southern Florida is one of the few places in the world where alligators and crocodiles live side by side. The Everglades area is an ecosystem. Ecosystems are places where living things exist (存在) with nonliving things, such as water and soil. Everything in an ecosystem affects everything else. If something new is brought into the ecosystem, it may cause problems. Change caused by humans brought big problems in the Everglades. As more people moved to Florida, new homes and businesses were needed. Because the Everglades area was large and beautiful, people thought it might be a good place to build. The ground, however, was too wet. In order to build homes, people drained water from some of the wet ground. Taking water out of the Everglades caused many problems. Animals that ate water plants or small fish had a hard time finding food. The wood stork and other waterbirds began dying. People worried that this special place would be lost forever. Today, a portion of the Everglades is a national park. The law protects animals and plants there. Homes and businesses cannot be built inside Everglades National Park. Because it is now protected as a park, part of the Everglades will be beautiful wetlands for many years to come. 1．What is special about the Everglades? A．It is an area of wetlands. B．It is in a desert. C．It has only trees. D．It is a city in Florida. 2．According to the passage, what can we know about an ecosystem? A．All ecosystems are exactly the same. B．It can only survive with human help. C．Changes in one part affect the whole system. D．Plants are more important than animals there. 3．The underlined word “drained” in Paragraph 4 means ________. A．gave out B．looked for C．used up D．took away 4．How is the Everglades protected today? A．By developing business. B．By making it a national park. C．By closing down to all visitors. D．By allowing people to build homes. 【答案】1．A 2．C 3．D 4．B 【导语】本文主要讲述了佛罗里达大沼泽是独特的湿地生态系统，因人类排水开发导致生态危机，现部分区域被划为国家公园受到保护。 1．细节理解题。根据第二段“The Everglades is an area of beautiful wetlands in southern Florida.”可知，大沼泽地是佛罗里达州南部一个美丽的湿地。故选A。 2．细节理解题。根据第三段“Everything in an ecosystem affects everything else.”可知，生态系统中的一切都会影响其他一切，选项C“一个部分的变化会影响整个系统”表述正确。故选C。 3．词句猜测题。根据“The ground, however, was too wet. In order to build homes, people drained water from some of the wet ground.”及常识可知，地面太湿了，建造房屋应从一些湿地上抽走了积水，选项D“消除，移走(水分)”意思相近。故选D。 4．细节理解题。根据最后一段“Today, a portion of the Everglades is a national park.”可知，现如今，大沼泽地的一部分是国家公园。故选B。 学科网（北京）股份有限公司 $
