Another natural wonder crying for help

题目一：倡议书（呼吁保护亚马逊雨林）

 

题目：

假设你是学校环保社团的社长，亚马逊雨林（Amazon Rainforest）正在遭受严重的砍伐和火灾，被称为“地球之肺”的它在哭泣。请你以社团名义写一份英文倡议书，呼吁同学们关注并保护这一自然奇观。内容包括：

 

1. 介绍亚马逊雨林的重要性（如提供氧气、栖息地等）；

2. 说明它正在遭受的破坏（至少2点，如砍伐、火灾等）及其后果；

3. 提出具体的帮助建议（至少2条），并呼吁大家行动起来。

 

教师思路精讲

 

一、题目整体分析

 

本题为倡议书，属于应用文中的公开号召类文体。初一学生写这份倡议书的核心是：奇观的价值要说清，破坏的严重性要讲明，帮助的方式要具体可行。亚马逊雨林离学生生活较远，但通过数据和事实（如“地球之肺”“无数动物家园”），可以让学生感受到它的珍贵和危机。语气要有紧迫感，但也要传递希望。

 

二、写作要点分析

 

第一段：介绍自然奇观的重要性

写出它在哪里、为什么重要。例如：“The Amazon Rainforest in South America is one of the greatest natural wonders on Earth. It produces more than 20% of the world’s oxygen, so people call it ‘the lungs of the Earth’. It is also home to millions of animals, birds, and plants that live nowhere else.” 这部分要让读者明白“失去它将是灾难”。

 

第二段：说明正在遭受的破坏及后果

至少写出2种破坏行为及其影响。例如：“But the Amazon is crying for help. Every day, large areas of forest are cut down for farming and building. Huge fires are also destroying the trees. As a result, many animals lose their homes, and the air becomes less clean. If the forest disappears, our whole planet will suffer.” 用具体现象让危机可视化。

 

第三段：提出建议并呼吁

至少写出2条学生能做到的建议。例如：“What can we do? First, save paper. Less paper means fewer trees are cut down. Second, tell others about the Amazon. The more people know, the more help we can give. Third, support organizations that protect the rainforest. Every small action matters.” 最后用号召句结尾：“Let’s answer the Amazon’s cry for help before it’s too late!”

 

三、语言与格式提醒

 

倡议书开头用“Dear schoolmates,”，结尾用号召句。用数据增强说服力。多用“We must...”“Let’s...”。语气要紧迫但有希望。

重要句型与词组

 

· The Amazon Rainforest is one of the greatest natural wonders on Earth.

· It produces... of the world’s oxygen and is home to millions of species.

· But today, this wonder is crying for help.

· Every day, large areas are cut down or burned for farming.

· As a result, animals lose their homes and the air becomes less clean.

· We cannot stand by and watch it disappear.

· Here is what we can do to help.

· Save paper to protect the forest.

· Tell your friends and family about the danger.

· Every small action can make a difference.

· Let’s answer the cry for help before it’s too late.

· lungs of the Earth, cut down, lose homes, stand by, answer the cry

 

高分范文

 

Dear schoolmates,

 

The Amazon Rainforest in South America is one of the greatest natural wonders on Earth. It produces more than 20% of the world's oxygen, so people call it "the lungs of the Earth". It is also home to millions of animals, birds, and plants that live nowhere else. Without the Amazon, our planet would be a very different and poorer place.

 

But today, this wonder is crying for help. Every day, large areas of the forest are cut down to make space for farms and roads. Huge fires also burn thousands of trees. As a result, many animals lose their homes, and the air becomes less clean. Scientists warn that if the destruction continues, the Amazon may disappear forever. We cannot stand by and watch.

 

What can we do to help? First, save paper. Use both sides of your notebook paper, and recycle old newspapers. Less paper means fewer trees are cut down. Second, tell your friends and family about the Amazon. The more people know, the more help we can give. Third, support organizations that protect the rainforest with a small donation. Every small action matters. Let’s answer the Amazon’s cry for help before it’s too late. Together, we can save this precious wonder.

题目二：求助信（写给联合国，请求拯救冰川）

 

题目：

假设你是一名关心地球的学生，北极和南极的冰川（glaciers）正在因全球变暖而快速融化，北极熊等动物失去家园。请你以学生代表的身份给联合国写一封求助信，请求国际社会采取行动。内容包括：

 

1. 描述冰川的重要性和正在面临的危机（融化速度、后果）；

2. 说明如果不采取行动会造成的灾难（如海平面上升、动物灭绝）；

3. 提出具体的请求（至少2条，如减少碳排放、保护极地等），并表达感谢。
