必备知识清单
一、写作主题 写与保护自然奇观相关的文章。 二、内容分析 保护自然奇观这一主题在高中英语写作中极具意义，它不仅引导学生关注环境保护，还锻炼了他们的论述能力。自然奇观，如壮丽的山脉、神秘的峡谷、独特的地质景观等，都是地球赋予我们的宝贵财富。然而，随着人类活动的不断增加，这些奇观正面临着前所未有的威胁。因此，探讨如何保护自然奇观，不仅是对自然美的颂扬，更是对环境保护责任的呼唤。在写作关于保护自然奇观的文章时，你可以从以下几个方面展开： 开篇 引言 ：简要介绍自然奇观的概念，以及它们为何值得保护。可以提及一些著名的自然奇观，如大峡谷、黄石公园等，以吸引读者的兴趣。 自然奇观的重要性 ：详细阐述自然奇观对生态系统、科学研究、文化传承以及旅游经济等方面的重要性。比如，它们为动植物提供了独特的栖息地，是科学研究的宝贵资源，同时也是人类文化和历史的重要组成部分。 面临的威胁 ：指出自然奇观当前面临的威胁，如气候变化、环境污染、过度开发等。这些威胁不仅损害了自然奇观的完整性，还影响了其生态功能和价值。 保护措施 ：提出具体的保护措施，包括加强法律法规、提高公众意识、推广可持续旅游等。强调个人、政府和社会各界在保护自然奇观中的责任和作用。 末尾 结论 ：总结文章的主要观点，呼吁大家共同努力，保护这些珍贵的自然遗产，让它们的美丽和神奇得以永续传承。 【 范文示例1】 Dear Lucy, I hope this letter finds you well. I've been thinking a lot about our recent trip to the Grand Canyon, and it made me realize how important it is for us to protect natural wonders like it. The Grand Canyon is such a breathtaking sight, with its vast size and colorful layers of rock. It's amazing to think that it was formed over millions of years! But when I was there, I also saw some litter on the trails and heard about how pollution is affecting the area. It made me sad to think that such a beautiful place could be harmed by human actions. I think we should do something to help protect natural wonders. Maybe we could start by picking up litter when we see it, or joining a local environmental group. We could also spread awareness about the importance of protecting these places by talking to our friends and family. What do you think I'd love to hear your ideas and maybe even work together on a project to help protect our planet's natural treasures. Write back soon! Yours, Emma 【 范文示例2】 Dear Diary, Today was an eye-opening experience. I visited the local nature reserve with my class, and we learned so much about the importance of protecting natural wonders. Our guide told us that many natural sites, like the Great Barrier Reef, are in danger because of pollution and climate change. It made me realize that these places are not just beautiful to look at; they're also crucial for the health of our planet. They provide homes for countless animals and help regulate our climate. I decided that I want to do something to help. I'm going to start by reducing my own carbon footprint. I'll walk or bike instead of driving, use reusable bags instead of plastic ones, and be more careful about recycling. I'll also try to spread awareness about protecting natural wonders among my friends and classmates. It feels good to know that I can make a difference, even if it's just a small one. I'm excited to see what else I can do to help protect our planet's natural treasures. Goodnight, Sam 【 范文示例3】 Protecting Our Natural Wonders Natural wonders like the Amazon Rainforest, the Great Wall of China, and the Niagara Falls are truly amazing. They're like treasures that our planet has given us to enjoy and appreciate. But unfortunately, many of these wonders are in danger because of human activities. Pollution, deforestation, and climate change are just some of the threats that natural wonders face. If we don't take action to protect them, we could lose these beautiful and important places forever. So what can we do to help We can start by being more responsible with our own actions. We can reduce our carbon footprint, recycle more, and be careful not to litter. We can also support organizations that work to protect natural wonders and spread awareness about their importance. Remember, protecting natural wonders is everyone's responsibility. Let's work together to keep these treasures safe for future generations to enjoy. 三、突破技巧 1. 明确主题 至关重要。在写作时，要清晰地表达出保护自然奇观的重要性。例如，可以开篇点题：“Nature's wonders, such as the Grand Canyon and the Great Barrier Reef, are not only breathtakingly beautiful but also crucial for the balance of our ecosystem. It is our responsibility to protect them.”（大自然的奇观，如大峡谷和大堡礁，不仅令人叹为观止，而且对维持我们的生态系统平衡至关重要。保护它们是我们的责任。） 2. 使用生动语言 能够增强文章的表现力。描述自然奇观时，可以运用形容词和比喻来描绘其美丽和独特性。比如：“The Grand Canyon, carved by the Colorado River over millions of years, displays a spectacular array of colorful rock layers, revealing the Earth's geological history.”（大峡谷是由科罗拉多河经过数百万年冲蚀而形成的，展示了色彩缤纷的岩石层，揭示了地球的地质历史。）这样的描述能够激发读者的兴趣和保护欲。 3. 结合具体实例 可以使文章更加有说服力。可以列举一些自然奇观面临的威胁，如污染、气候变化等，并给出具体的保护措施。例如：“Due to human activities such as deforestation and pollution, many natural wonders are facing threats. We can take action by reducing our carbon footprint, recycling, and supporting sustainable practices.”（由于砍伐森林和污染等人类活动，许多自然奇观正面临威胁。我们可以通过减少碳排放、回收利用和支持可持续做法来采取行动。） 4. 呼吁行动 是文章结尾的重要部分。可以鼓励读者从自身做起，为保护自然奇观贡献一份力量。比如：“Let's all take responsibility for protecting our planet's natural wonders. By making small changes in our daily lives, we can make a big difference.”（让我们都承担起保护地球自然奇观的责任。通过在日常生活中做出小小的改变，我们可以产生巨大的影响。） 2这样的结尾能够激发读者的共鸣和行动意愿。

Good morning, everyone. I’m happy to introduce myself here. I hope to be one of the Earth protectors this year.
I am Li Hua, a fourteen-year-old student. I like fishing and making things by myself. And I also like making friends. I think environment is very important to everyone. Trees, rivers and lakes on the earth are treasures of human beings. They provide us with a beautiful home. However, the waste of wood and water do harm to our home—earth. We have to take action to change the situation.
If I am the Earth protector, I will call for volunteers to plant more trees. Besides, I will advise students to use cloth bags instead of paper bags, so that we can save more paper and wood. As for water, everyone should remember to turn off the tap. We students should be supervisors of our family members.

Dear Leo,
I hope you’re doing well. I’m writing to share a piece of exciting news with you. Our school held activities to teach students about planting trees and protecting the environment.
The event began in the afternoon on 12 March with a lecture on how to protect trees. Following that, my classmates and I took part in a tree-planting activity. By taking part in this event, I learnt more about the importance of trees. They not only create cleaner air for us to breathe but also make our lives more convenient. I can’t imagine a world without them. I call on people to protect them from now on.
I’m looking forward to knowing about your experiences.
Yours,
Li Hua
