中职英语高教版（2021）基础模块3Unit 7 Natural Disasters一等奖教案

Unit 7 Natural Disasters

  教学设计（二）

第三、第四课时 Reading and Writing

一、教材分析

本课教学内容选自教材Unit 7 Reading and Writing部分，读写部分是一篇有关自然灾害和人类活动的议论文，文中主要提 到了三种因人类活动导致的自然灾害和应对措施，并提出了可持续发展对人 类和对大自然的重要性，呼吁人们注重环境保护并给出减少自然灾害的一些措施。要求学生能通过阅读文章找到细节信息，明确文章目的，通过细读文章提取文中自然灾害的原因和应对措施，能看到事实和观点并找到支撑信息，能使用相应的词汇和句型描述，自然灾害和环境保护，完成环保宣传海报。

二、学情分析

经过前两节课的学习，学生能识别关于自然灾害的词汇，并做简单介绍，能够意识到自然灾害有部分原因是来自于人类活动，但是缺乏语言积累，无法详细的描述自然灾害和人类活动的关系。进行开放性的思考和讨论还存在一定困难。

四、教学重点、难点分析

教学重点：能通过阅读，提取文中自然灾害的原因和应对措施，能判断事实和观点并找到支撑信息。

教学难点：能使用恰当的词汇与句型，进行开放性的思考和讨论，完成环保的宣传海报。

五、教学过程

Before class：

* 1. 复习活动： 学生课前完成关于自然灾害的思维导图

 Can you name some natural disasters?

During class:

Step 1 Lead in

1. 教师展示自然灾害的图片，学生谈论感受。教师引出单词：

violence ['vaiələns]  n. : behavior which is intended to hurt, injure, or kill people  

 violent ['vaiələnt]   adj.

* 2.教师提问：

Q: What is the violence of nature shown by?

A: The violence of nature is shown by NATURAL DISASTERS.

Step 2　Pre-reading

1. Think and discuss. 处理教材活动9。

（1）学生讨论：“以下哪种情况可能导致自然灾害”？为后续阅读活动做铺垫。此环节可以用希沃白板、UMU等教学辅助平台，采取投票的形式开展。

Possible answers:

A. Strong wind blowing over loose soil or sand.

C. Rapid urban development and heavy industries.

D. Volcanoes and wildfires.

*（2）拓展活动：教师展示投票的统计数据，学生讨论并回答问题：

A. Strong wind is blowing over loose soil or sand may cause sandstorm.

C. Rapid urban development and heavy industries may cause smog or heat waves.

D. Volcanoes and wildfires may cause floods or heat waves.

（设计意图：本活动是读前活动，要求思考并选择造成自然灾害的原因，训练学生的审辩

思维能力，为后续活动做铺垫。）

Step 3 While-reading

1. Read and underline.

处理教材活动10，可分两步：

（1）Please go through the passage quickly to find the main idea of the passage.

学生快速浏览文章，找出文章大意。

（2）拓展活动：快速浏览文章，填空，列出文中提到的自然灾害及产生的原因。

Sandstorms are caused naturally by strong winds blowing over loose soil or sand.

Smog is partly caused by the gases from heavy industry and vehicles.

2. Read and complete.

（1）处理教材活动11。学生细读课文找出导致文中自然灾害的原因及应对措施。

（2）梳理课文语言点及词汇。

*（3）拓展活动：填空题，学生依据上面的表格，自然灾害产生的原因，并辨析其产生原因是自然原因还是人类活动。

（设计意图：本环节通过学生细读文章，提取有关导致自然灾害的原因及应对措施等具体信息，完成表格的填写，锻炼逻辑思维能力，为后续的写作活动做语言上的准备。）

Step 4 Post-reading

1. Read and match. 处理教材活动12。

学生再读文章，判断下列陈述哪些为事实，哪些为观点，并为观点找出支撑性的语句,在文章中勾画下来。

2): Experts tie the problem to the rapid urban development, and cutting down trees is another reason which is largely due to human activities. Some people do not pay enough attention to smog, and they don’t know it is partly caused by the gases from heavy industry and vehicles.

4) It is lucky that humans have realized the importance of sustainable development as well as the environmental protection, and things are getting better. We are promoting the use of green energy, planting more trees and trying to stop global warming. People are advised to use electric cars and public transportation.

（设计意图：学生通过理解文章，能够判断客观事实和个人观点的表述，并找出支撑信息，锻炼审辩思维能力，搭建思维脉络，为写作做准备。）

Step 5  Writing

1. Read and write. 处理教材活动13。

*（1）铺垫活动：教师呈现常见灾害的图片或视频，学生仿照阅读材料，开展小组讨论列举人为原因造成的自然灾害以及其他应对的建议。

（2）教师提供必要的语言材料，引导学生讨论自然灾害产生的原因，反思人类活动对环境造成的影响。

参考语言材料：

参考答案：

As we know, Mudslide is a common natural disaster. It is caused by cutting too many trees. I think that we need to stop cutting trees and plant more trees.

Nowadays, more and more people suffer from skin cancer. One of the reasons is that they are exposed to excessive ultraviolet radiation（紫外线辐射）. This is due to the hole in the ozone layer. Freon contained in air conditioners used by people destroys the ozone layer. For the sake of our health, we should try our best to use fluorine-free air conditioning.

The destructive power of the tsunami is amazing. This is because people cut too many trees. Human over logging has left the coastline unprotected. I think we should Stop deforestation and build an ecological barrier.

（3）学生小组分享写作，师生分别进行评价。

3. Write and practice. 处理教材活动15。

（1）铺垫活动：以一篇小文章引入

Sandstorms have been a major disaster for many Asian countries for centuries. Scientists have tried many ways to solve this problem and in China, a mass campaign has been started to help solve it.

教师提问：Should we join the mass campaign? 

What can we do? 

It’s time to act. Let’s make a poster for it.

教师可采取多种方式引入，如：播放环保宣传的演讲视频，介绍“蚂蚁森林”等公益项目。

（2）学生分小组，仿照阅读材料，梳理语篇结构（现象、原因、解决措施），讨论宣传环境保护的海报的内容。

（设计意图：通过开放性的讨论引导学生思考并讨论人为造成的自然灾害有哪些，提出更多的应对举措，建议以此提升学生的思维素养和文化素养，培养分析能力，拓宽视野，进一步加深环保意识。）

Step 6 Conclusion.

教师引导学生围绕以下两方面，结合本单元读写部分微课，总结本课所学：

*（2）阅读补充阅读，回答问题

Supplementary reading

Why is the smog in China so bad?

                               --It’s getting harder and harder to breathe

                                                By Mary Beth Griggs

January 6, 2017

Earlier this week, a thick layer of smog rolled into China’s capital city, turning skyscrapers into shadows and clear air into a yellow fog. Caught on a shoot by Chas Pope, the smog rolls in like a dust storm in a desert, billowing into the streets of Beijing.

Smog destroyed air quality in Beijing and 24 other Chinese cities this week, leading authorities to declare a national red alert for “severer frog” —the highest level of alerts.

This isn’t the first time that smog has blanketed China. In recent years, poor air quality in Beijing has closed schools and caused farmers in the region to panic(恐慌) over the lack of sunlight.

Why does smog keep blanketing Beijing? Smog in China has many causes, including pollution from industries and traffic. But burning coal has been linked to the largest number of air pollution deaths in China, causing 366,000 premature deaths in 2013.

China is taking steps to solve the problem. The government has restricted driving in an effort to staunch air pollution from cars. But that measure is temporary. Chinese officials announced this week that the country would spend $360 billion on renewable energy projects. But it has a long way to go. China is still the world’s largest consumer of coal by far, and plans to continue using the sooty source of power.

Question 1: Which city suffered from the smog?

Question 2: Why does smog keep blanketing Beijing?

Question 3: What steps is China taking to solve the problem?

参考答案

Question 1: Beijing

Question 2:

1.pollution from industries and traffic 

2.burning coal

Question 3:

1. The government has restricted driving in an effort to staunch air pollution from cars.

2. Chinese officials announced this week that the country would spend $360 billion on renewable energy projects.
