Unit 4 Global warming
Reading: The earth is becoming warmer
--- but does it matter?
Learning aims:
1) Learn some knowledge about the greenhouse effect and global warming.
2) Know the contents of the text well by talking about this topic and reading.
3) Discuss the problem of global warming and express your own opinions.
Learning difficult points:
Master the main idea of the first five paragraphs by talking about the topic.
Learning important points:
Know about different opinions towards global warming and express our own opinions.
Teaching procedures:
Step I. Greetings
Greet the whole class as usual.
Step II. Lead-in
Lead to the topic by showing an article to the students and let students know about two types of greenhouse effect ("natural" greenhouse effect and “man-made” greenhouse effect) and their exact meanings.
Step III. Analyze two graphs to learn the main idea of the first five paragraphs.
From the first graph, we can see that during the 20th century the temperature of the earth rose about one degree Fahrenheit.
All scientists agree with the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy.
More such burning means more carbon dioxide added to the atmosphere.
