UNIT 3
ENVIRONMENTAL PROTECTION
Reading and Thinking
Learning Objective
By the end of the class, students are able to
accumulate some words about climate changes and environmental protection
identify the style of this text and infer the writer’s purpose
to think about the measures of environmental protection
Part 1
Warming-up
When you are encounted with environmental problems, what do you think?
The earth is crying. People are trying to use the environment to maximize the use of resources.
1. What’s happening in the photo?
The ice is melting.
2. Why did it happen?
Because of the greenhouse effect/global warming.
Part 2
Pre-reading
What is global warming?
Global warming
natural disasters
economic losses
coastal cities submerged
extreme weather
unpredictable future of human
animals dying
What is global warming?
How do you protect the environmental protection?
Part 3

What is the graph about? What information can you get from it?
The graph shows the change in the Global Surface Temperature between 1920 and 2016.
Scanning
What is the graph about? What information can you get from it?
It shows the temperature anomaly, which shows how much the temperature has risen above what it would usually be at a base level.
What happened to the polar bear in the photo? What might be the story behind it?
The polar bear in the photo died of starvation.
The story is that the polar bear starved to death because it could not find enough to eat.

Para. 1: What evidence of climate change can you find in this paragraph?
A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate.
Skimming
Para. 2: Can you use your words to describe how climate change have influenced the polar bear's life?
climate change
low sea-ice levels
bears could not hunt
had to travel greater distances to find food
starved to death
its dead body found
Skimming
Para. 3: Find the key precess about “greenhouse effect”.
Greenhouse effect
natural greenhouse effect
keeping Earth's climate warm and habitable
man-made greenhouse effect
causing Earth’s surface temperature to rise quickly if too much heat energy is trapped
Skimming
Para. 3: Use a diagram describing how the greenhouse effect works.
Skimming
Para. 3: Why is the “natural” greenhouse effect important and neccessary?
Skimming
Para. 4: Group work: Draw a mind map to show the relationship of this paragraph.
The rise in temperature
extreme weather / natural disasters
extreme rainstorms, heat waves
serious damage, costing human lives, economic losses

Para. 5: What should we do to reduce greenhouse gas emissions?
Language Points
1. The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth’s surface as short-wave radiation.

reference n.提及；谈到；参考
in/with reference to关于

2. There is little doubt that Earth is getting warmer and warmer.
doubt的常见句型：
There is some doubt whether... ……有些疑问。
There is no doubt that... ……是毫无疑问的。
I doubt whether/if.../I have some doubt whether... 我怀疑……
I don’t doubt that.../I have no doubt that... 我毫不怀疑……

2. There is little doubt that Earth is getting warmer and warmer.
①There is some doubt he will be elected president.
②I never doubt special classes can help the gifted children to graduate earlier and take their place in life sooner.
③毫无疑问，当你筋疲力尽时，一杯茶可以使你精力充沛。
a cup of tea can make you dynamic when you are worn out.
whether

Language Points
3. It is our responsibility to seize every opportunity to educate everyone about global warming，along with its causes and impacts，because this is the most serious issue affecting all of us on this planet.
seize sb. by the＋身体部位 抓住某人的……
seize a chance/an opportunity 抓住机会
例如：我们应该抓住机会努力工作来实现我们的目标。
We should seize the opportunity to work hard to achieve our goal
Language Points
4. ...the bear appeared to have starved and died.
starve for 渴望；极想得到 starve to death饿死
starvation n.饥饿；饿死 die of/from starvation饿死
starving adj.极想的；渴望的 be starving for渴望得到
例如：我渴望得到一个机会学习如何包饺子。
I starve for/am starving for a chance to learn how to make dumpling.
Language Points
5. We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce.
restrict...to...把……限制在……
例如：俱乐部成员的数量被限制在10人以内。
The number of the club members is restricted to ten.
Part 4
Post-reading
Why is a question left at the end?
Group work:
To leave readers’ deep thoughts of how to reduce greenhouse gas emissions.
Do you think climate change is the result of man's greed?
Let’s think:
I do think that climate change is the result of human activities because the majority of scientists also think so, and also because global temperatures have followed the rise in global emissions and population.
What examples of extreme weather and disasters do you know?
Let’s think:
There are sadly many examples of extreme weather and disasters I know of, such as the extreme rainfall in France and the drought in East Africa in 2014. There were also heatwaves on nearly every continent due to climate change.
Who do you think should take responsibility for dealing with climate change?
Let’s think:
I think we all need to take responsibility for dealing with it.Individuals can change their behaviour and try to reduce their carbon footprint,while companies and governments can do the same on the larger scale.
Thanks for your listening!
