Climate Change Requires The World’s Attention
By the end of this class, we will be able to
1. know the causes and consequences of climate change.
2. explore practical ways to address climate change.
3. figure out effective information on graphs and diagrams.
Learning objectives
Look at the graph. What information can you get from it
The earth is becoming warmer and warmer.
Pre-reading
The polar bear (北极熊) was skin and bones and starved to death.
What may be the cause of the death of the polar bear
What can you see in the photo
Global warming causes the melting of iceberg
and some polar bears may have suffered from the
lack of food.
In the expository text, the authors sometimes use some graphs or diagrams in their essays in order to convince their readers.
Fast-reading:Read for the main idea and the structure.

Part 2:
(para. 3)
Part 3:

The evidence(证据) of dramatic climate change that had an impact on Earth’s ecology
The causes(原因) of the increase in the global average surface temperature
The consequences(结果) of the rise in temperature

Function
Keeping Earth’s warm and_____________
Definition
People produce huge amounts of_________ greenhouse gases by burning_____________.
A big problem
More ________ energy is trapped in the atmosphere and causes Earth’s surface temperature to ________ quickly.
habitable
extra
fossil fuels

rise
Greenhouse Effect
Task 4: Read Para 3 and fill in blanks:
Can you create a diagram describing how the greenhouse effect works
Heat released back into space
Heat reflected back to Earth’s surface
Reflected sunlight
Atmosphere
Sunlight
Draw a diagram
Diagrams are very useful tools that can be used to brainstorm ideas, map out processes, show cause and effect relationships, explain a new idea or concept, and so on. When you read an essay about scientific issues, you can try drawing a diagram, which will not only allow you to visualise the problems more clearly but also can help demonstrate your creative thinking and problem-solving.
The consequences of the rise in temperature
In Para 4, why did the author mention the climate scientists’ warning
Because it is essential that we take action and so it needs to be brought to everyone’s attention.
Find the key sentence of Para 4

Expository writing
本文按照“证据—原因—危害—措施”的逻辑顺序展开,环环相扣,步步深入。标题Climate Change Requires the World’s Attention点明了作者的诉求:气候变化对地球生态系统的影响是巨大的,需要全人类共同关注和面对。文本以现在时态和将来时态为主,强调文章的现实意义及对将来不利后果的预测。
Earth provides enough to satisfy every man’s needs, but not every man’s greed.
— Mohandas K. Gandhi
Such as shelter, air, food, water and the means to do something productive and meaningful.
Greed is a desire that can never be satisfied.
Needs mean all basic living things
The quote is used here to suggest that consumption powered by greed is a prime cause of environmental degradation (环境恶化).
Over logging, polluted water resources …
Earth provides enough to satisfy every man’s needs, but not every man’s greed.
— Mohandas K. Gandhi
地球能满足每个人的需要,但不能满足每个人的贪婪。
we should cherish what we have and do whatever we can to make the world a better place, leaving the green mountains and blue waters for our offsprings.
Only by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves.
Lucid waters and lush mountains are valuable as "mountains of gold and silver".
青山绿水就是金山银山。
If we don't save water, the last drop of water will be our tear.
如果我们不节约用水,那么最后一滴水将会是我们的眼泪。
When the sky becomes blue again and the rivers become clean, we'll live a healthier and happier life.
当天空再次变得湛蓝,河水变得清洁,我们会过上更健康、更快乐的生活。
