Period 1: Reading and Thinking
Climate Change Requires the World’s Attention
Unit 3 ENVIRONMENTAL PROTECTION
Starved polar bears
Lead in
The effects are destructive as follows:
The sea level to rise.
Severe storms, floods, droughts, famines, the spread of diseases, and destruction of species.
Wide animals died because of starvation.
Forest fire occurs frequently because of the extreme hot weather.
What do you know about global warming
What is the graph about
2. What information can you get from it
Research into the pictures
It’s about the change of global surface temperature.
It shows us that the global temperature
is rising steadily and continuously.
2. What happened in the picture
What may be the cause of the death of the polar bear
Global warming causes the melting of iceberg
and some polar bears may have suffered from the
lack of food.
A dead polar bear was found and it is “skin and bones.”
Read the text and work out the main idea of each paragraph.

Global climate is changing dramatically.
An alarming case about a bear starved to death
What is causing the increase in the global average surface temperature
The bad effects of the rise in temperature and the warning
Further possible changes to the global climate and our duty
Skimming
Read the text and answer the questions:
1. What is the evidence of global warming
2. Why is the “natural”greenhouse effect important and
necessary
3. What are the consequence of high greenhouse gas emissions
4. Why did the author mention the climate scientists’ warning
5. What is the author’s purpose of writing the text
Detailed-Reading
1. What is the evidence of global warming
2. Why is the “natural ”greenhouse effect important and necessary
Because greenhouse gases trap heat and keeps the earth
warm and habitable.
Warming ocean and atmosphere; melting and rising sea level; the starved polar animals; the extreme weather and natural disasters
Read the text and answer the questions：
Detailed-Reading
3. What are the consequences of high greenhouse gas emissions
People produce huge amounts of extra greenhouse
gases and more heat energy is trapped, causing the
temperature to go up.
Detailed-Reading
4. Why did the author mention the climate scientists’ warning
5. What is the author’s purpose of writing the text
Because the writer wants to warn us of the urgency of taking appropriate actions to tackle the issue.
To arouse our awareness of the problem of the rise of temperature and taking proper actions to deal with the global warming.
Detailed-Reading
1. What kind of extreme weather patterns and disasters do you know of Make a list of them.
2. Do you think it is human activity that caused global climate change Give your reasons.
3. Who should take responsibility to address this climate change What should you do to tackle it
Group discussion
1. What kind of extreme weather patterns and disasters do you know of Make a list of them.
Tsunami, floods, landslides, sandstorms, thunderstorms, hail, hot waves, cold current, typhoon, tornado, hail
Group discussion
2. Do you think it is human activity that caused global climate change Give your reasons
Yes. Human beings burn too much fossil fuels
and produce large quantities of carbon dioxide,
causing the temperature to go up quickly.
Group discussion
3. Who should take responsibility to address this climate change
It is everyone’s duty to take care of the earth and do
our part to tackle global warming.
Group discussion
Take the stairs instead of the elevator
What can we do to tackle it
Don’t litter!
What can we do to tackle it
Go to school or work by bike /bus instead
of driving a car.
What can we do to tackle it
What can we do to tackle it
What can we do to tackle it
Use a handkerchief instead of tissues
Use reusable baskets or eco-friendly bags instead of plastic bags; buy things economic with energy; use recyclable goods or items.
What can we do to tackle it
What can we do to tackle it
plant more trees
What can we do to tackle it
Climate is changing.
Evidence
damages
Potential further changes
causes
summary
warning
actions to tackle the issue
Homework
Write a composition on
Global warming in my eyes
What is global warming
How does it come about
What harmful effects dose it cause
How to stop it
