Verb;
2. 能在语境中恰当使用上述强调结构传递 信息和表达意义，谈论环境问题

What’s the worst change for our atmosphere
What demonstrates the
villainy of carbon dioxide
Why does the author use the
sentence pattern “It is … that …”
In this way, the author can
emphasize the subject “the melting of the ice caps” .
Identify forms of emphatic structures
Read the paragraph and answer the questions.
l It is the melting of the ice caps that is the worst change.
l The melting of the ice caps does cause the worst change.
Underline the sentences with emphatic structures in the dialogue.
A: Is carbon dioxide harmful
B: No. It makes up a very small percentage of the gases in the world. In fact, carbon dioxide is essential for life. It is carbon dioxide that plants need to produce “food” .
A: In that case, the more the better
B: Well, it’s not often the case. It is due to the increase in the concentration of carbon dioxide in the
atmosphere that the planet’s average temperature is going up. It is the greenhouse effect that we call it. A: So, is the earth getting hotter
B: Yes. The increased temperature does change our world for the worse. The polar ice caps are melting, and our sea level is rising.
A: How can we stop global warming
B: All nations across the world need to work together. It is all of us who should take the challenge.

Bob: It is since the Industrial Revolution that the burning of fossil fuels have released carbon dioxide.
Alex: When we focus on the development of humans, the oneness of heaven and human can’t be ignored. If we continue ignoring it, what will we face
Bob: It is the significant climate change or extreme weather that we will face. We should commit to sustainable development.
The discussion between Alex and Bob
