This year's theme “Planet (行星) vs. Plastic” is especially important because plastic is harming our environment in many ways. Plastic doesn't break down easily. 1 To fight against plastic pollution, we all need to do something. Governments can make rules to limit the use of plastic and encourage people to recycle. Businesses should find ways to use less plastic or use recycled plastic instead. International cooperation (合作) is of great importance, as many environmental problems need worldwide support. 2 Schools can help too. 3 By taking part in activities like zero-waste events at school, we will be more likely to make proper choices in our daily lives. We can also share what we know with our friends and families. 4 We are advised to use reusable shopping bags and glass bottles instead of plastic ones. It’s a good idea to try to buy something without a lot of plastic packaging (包装). Even small changes in our daily habits can be helpful. Earth Day is a perfect chance to have our voice heard. 5 Let’s work together towards a greener world. A．We students can make a difference. B．This simple habit can reduce our plastic waste. C．Remember that every little bit helps to protect the Earth for the future. D．They can teach students the harm of plastic pollution and lead us to take action. E．This means it can stay in environment for a very long time, hurting animals and plants. F．By working together, countries can share knowledge and resources to make a better world. 【答案】1．E 2．F 3．D 4．A 5．C 【导语】本文主要介绍应对塑料污染，我们应该采取的措施。 1．根据上文“Plastic doesn’t break down easily.”可知，塑料不容易分解，选项E“这意味着它可以在环境中停留很长时间，伤害动植物。”符合语境。故选E。 2．根据上文“International cooperation (合作) is of great importance, as many environmental problems need worldwide support.”可知，此处与合作应对塑料污染有关，选项F“通过共同努力，各国可以分享知识和资源，创造一个更美好的世界。”符合语境。故选F。 3．根据上文“Schools can help too.”可知，此处与学校采取的措施有关，选项D“他们可以教学生塑料污染的危害，并引导我们采取行动。”符合语境。故选D。 4． 根据下文“Even small changes in our daily habits can be helpful.”可知，此处说的是学生们的帮助，选项A“我们学生可以有所作为。”符合语境。故选A。 5． 根据下文“Let’s work together towards a greener planet.”可知，此处说的是作者的号召，选项C“请记住，每一点都有助于保护地球的未来。”符合语境。故选C。 七、阅读表达。 阅读短文，根据短文内容回答问题。 April 22, 2024 marks the 55th World Earth Day. This year’s theme is “Planet vs. Plastics” (全球战塑). So, I decided to try something different: a whole day without using any plastic. It sounded exciting, but it was quite hard. My morning started with a homemade breakfast in a glass bowl. But later when I tried to order juice as usual, I had to give up because of those plastic cups. I faced a bigger problem at the supermarket. Almost everything was wrapped (包装) in plastic—from fruits and vegetables to meat. It made me realize that plastic is everywhere, making it hard to carry on with my no-plastic plan. Plastic is widely used in our daily life. It can be made into all kinds of things such as bags, bottles and toys. It’s tough (牢固的) and it’s really light. So we depend heavily on it. But there’s one thing: Using too much plastic can be harmful to the environment. Humans use about one million plastic bottles every minute, and more than 5 trillion plastic bags are used each year, according to a United Nations report. The world produces 200 million tons of plastic waste each year, but only less than 10 percent has been recycled. Most of them end up in the lakes, rivers and oceans, hurting animals and nature. To make a difference, China stopped the production, sale and use of plastic shopping bags with a thickness of less than 0.025 mm in 2008. From 2010 to 2020, China recycled 170 million tons of waste plastic. These have helped reduce plastic waste. Let’s join hands and make a clean and beautiful world. 1．What did the writer decide to do to support the World Earth Day? ______________________________________________________ 2．According to the passage, why is plastic useful but harmful? (No more than 20 words.) ______________________________________________________ 3．What can you do to help reduce plastic waste? ______________________________________________________ 【答案】1．He decided to try something different: a whole day without using any plastic. 2．Because plastic is widely used in our daily life, but using too much plastic can be harmful to the environment. 3．I will try my best not to use plastic products. 【导语】本文简述了塑料的广泛使用及其对环境的影响，特别是塑料垃圾对自然和动物的危害。同时，提到了中国为减少塑料污染所采取的措施，并呼吁大家共同努力，保护环境，减少塑料使用。 1．根据“So, I decided to try something different: a whole day without using any plastic.”可知，作者决定尝试一些不同的东西：一整天不使用任何塑料。故填He decided to try something different: a whole day without using any plastic. 2．根据“Plastic is widely used in our daily life.”及“But there’s one thing: Using too much plastic can be harmful to the environment.”可知，因为塑料在我们的日常生活中被广泛使用，但使用过多的塑料会对环境有害。故填Because plastic is widely used in our daily life, but using too much plastic can be harmful to the environment. 3．开放性试题，言之有理即可。参考答案为：I will try my best not to use plastic products. 八、阅读理解。 阅读下面短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。 A new study has found that light pollution is making the night sky brighter and the stars dimmer (暗淡). The study examined data (数据) from more than 50,000 star watchers across the world. It found that man-made lighting is making the night sky about 10 percent brighter each year. Data for the study was collected from 2011 to 2022. The research findings recently were written in a book. The result was a much faster rate of change than scientists had guessed in the past. “We are losing, year by year, the chance to see the stars,” said Fabio Falchi. He is a physicist at the University of Santiago de Compostela in Spain. He was not a researcher in the study. “If you can still see the dimmest stars, you are in a very dark place.” Falchl said. “But if you see only the brightest ones, you are in a very light-polluted place.” As cities expand (扩大) and put up more lights, a “sky glow” is created in the sky. “Sky glow” is a word scientists use to describe light that becomes more intense (强烈的). The research team gave an example to make the result clear. If a child is born where 250 stars can be seen on a clear night, by the time that child turns 18, only 100 stars will be seen. Light pollution influences (影响) more than our view of the heavens. Research shows that lots of nighttime light can harm wildlife. 1．What kind of pollution is the passage talking about? A．Waste pollution. B．Land pollution. C．Noise pollution. D．Light pollution. 2．How long was data for the study collected? A．For about eight years. B．For about ten years. C．For about twelve years. D．For about fourteen years. 3．Which of the following is NOT true according to the passage? A．The study examined data from over 50,000 star watchers across the world. B．The research findings recently were written in a book. C．Fabio Falchi thinks we are losing chances to see the stars year by year. D．If you can see only the brightest stars, you are in a very dark place. 4．The passage wants to tell us that ________. A．light pollution is bad for the environment. B．man-made lighting is making the night sky more beautiful C．“sky glow” is a word that scientists use to describe dim light D．children can only see 100 stars when they grow up 【答案】1．D 2．C 3．D 4．A 【导语】本文主要介绍了光污染是什么，以及它对人类生存环境的影响。 1．细节理解题。根据第一段“A new study has found that light pollution is making the night sky brighter and the stars dimmer (暗淡).”可知，本文谈论的是光污染。故选D。 2．推理判断题。根据第三段“Data for the study was collected from 2011 to 2022.”可知，这项研究的数据是从2011年到2022年收集的，约12年。故选C。 3．细节理解题。根据第五段“But if you see only the brightest ones, you are in a very light-polluted place.”可知，如果你只看到最亮的星星，那你就处在一个光污染严重的地方，而不是一个很暗的地方，故选D。 4．主旨大意题。阅读全文并根据最后一段“Light pollution influences (影响) more than our view of the heavens. Research shows that lots of nighttime light can harm wildlife.”可知，光污染对环境是有害的，故选A。 Pollution: A Problem We Need to Solve Part 1: Read and Explore Pollution is a serious problem in our world today. It means making our air, water or land dirty and unsafe. There are many kinds of pollution around us, such as air pollution, water pollution and land pollution. Pollution is bad for our health, our environment and all living things on Earth. We must work together to reduce pollution and protect our home. Air pollution is very common in big cities. Cars, factories and burning things all make the air dirty. Breathing dirty air can make us sick, and it is also bad for plants and animals. Water pollution happens when people put dirty things into rivers, lakes or oceans. It makes water unsafe to drink and kills fish and other water animals. Land pollution is caused by rubbish and waste, which makes the land dirty and ugly. Pollution brings many bad effects to our life. Dirty air makes it hard for us to breathe, and some people get ill because of it. Polluted water can make us sick if we drink it. Rubbish on the land not only looks bad but also harms animals that live on the ground. Over time, pollution can make our Earth worse and worse, and it will be hard for us to live a happy life. We are not too young to help solve the pollution problem. There are many simple things we can do every day. We can walk or ride bikes to school instead of taking cars, which can reduce air pollution. We can put rubbish into dustbins and separate waste to help with land pollution. We can also save water and not pour dirty water into rivers to protect water. Protecting our Earth from pollution is everyone’s duty. If we all do a little, we can make a big difference. We should try our best to keep our air clean, our water clear and our land tidy. Let’s work together to fight pollution and make our world a better place to live in. Part 2: Skills Challenge Task 1: Critical Thinking（根据文章内容回答下列问题 ） 1. Why is pollution a serious problem?
