Extra greenhouse gases.
Lead-in
Review the passage and answer the questions.
3.Where do greenhouse gases come from
Many greenhouse gases occur naturally in the atmosphere, while others are man-made. Most of the greenhouse gases of human-caused come primarily from fossil fuels — coal, natural gas, and petroleum (石油，原油) — for energy use.
The large amount of extra man-made greenhouse gases is directly related to the problem of global warming. Besides that, the greenhouse gases have been influencing our daily life.
Lead-in
Watch a video about man-made greenhouse gases
Lead-in
Discuss the following questions after watching the video
1. What information can you get from the video
2. How do these situations influence your life
From the video I can see chimneys are in a power station and the sky is grey. Both places look very polluted. I can see some coal being burned.
These situations influence my life not only by providing electricity for me, and transporting me, but also by polluting the air I breathe. From the video I know the air pollution can cause serious health problem.
Pre-listening
Before you listen, look at the pictures below and discuss the questions
The bridge is in London.
The chimneys are in a power station.
the burning coal
They all look very polluted.
Pre-listening
Before you listen, look at the pictures below and discuss the questions
What is it And what do you think about it
NEVs
(new energy vehicles)
New energy vehicles can be powered by electricity. They are the breakthrough point for China to develop new energy automobiles.
Pre-listening
Before you listen, look at the pictures below and discuss the questions
Judging from pictures and questions above, Can you guess what the interview will talk about
These pictures tell me that the interview is probably about energy and pollution.
Skim Activity 2. What do you think the air pollution expert might talk about
Some key words: smog, combination, fossil fuels, wood etc.
While-listening
Listen to the interview with an air pollution expert and decide whether the statements are true (T) or false (F).
1. The expression “smog” originated in Britain and means a combination of “smoke” and “fog”.
2. Smog became a severe problem in Britain because people at that time burnt lots of fossil fuels.
3. The worst smog in British history happened in London in 1942.
4. The Great Smog of London claimed 5,000 lives.
