What’s happening in the picture Where is it
The picture showed us Glacier melting, we can see a large piece of ice breaking off a large glacier.
It is likely to be in the Arctic or Antarctica or somewhere nearby.

Expository essay
The authors sometimes use some graphs or diagrams in their essays in order to convince their readers. These graphs and diagrams often come from scientific reasearch reports and other reliable resources.
predict:
1.What is the graph about What information can you get from it
2. What do you think might have caused the polar bear's death
read for the structure:
1. search for the topic sentence of each paragraph and summarize the main idea.
2. divide the passage into several parts
Task 1: Find the key sentence of each paragraph and summarize the main idea of each part:
Para 1
Para 2
The evidence of dramatic climate change that had an impact on Earth’s ecology
瘦骨嶙峋
Para 3
The cause of the increase in the global average surface temperature
Para 4
Para 5
The consequences of the rise in temperature
The solutions to reducing greenhouse gas emissions

Task 2: Read for details
Read Para 1-2 and answer the question:
Find the cause and effect that can show how climate change has influenced the polar bear’s life
Find the cause and effect that can show how climate change has influenced the polar bear’s life

low sea-ice levels
bears could not hunt
had to travel greater distances to find food

1. “greenhouse effect”.
__________ greenhouse effect
_________ greenhouse effect
causing Earth’s surface temperature ______________ if too much heat energy is _______
keeping Earth’s climate _______ and __________
natural
man-made
warm
habitable
to rise quickly
trapped
Read Para 3 1.make a mind map about greenhouse effect
2. create a diagram describing how it works
Read Para 4 and sort out the text information relationship.
The rise in temperature
extreme weather / natural disasters
extreme rainstorms, heat waves
serious damage, costing human lives, economic losses
leads to
examples
results
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.
Read Para 5 and answer the questions:
How can individuals reduce “carbon footprint”
What is the author’s purpose of writing this text
We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce.
The author’s purpose is to inform the readers and inspire them to do whatever they can to deal with this problem.
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 …
Homework
Search for some rules and regulations set up by the government and explain the core idea as much as possible next period.
