Ancient animal and plant material below the surface of the earth with a high carbon content, such as coal, oil and natural gas, which can be burnt to produce energy. Also known as non-renewable energy because once they are used they have gone forever; they cannot be renewed. What is a greenhouse made and used for? A greenhouse is made of glass and is used for growing plants, especially during cold weather.How does it work?
The air inside is warm because the glass traps the heat from the sun and keeps it from escaping. This makes the greenhouse heat up and so the
plants can grow
throughout the
cold period.What are the “greenhouse gases”?
In the atmosphere surrounding the earth there are gases, which are called “greenhouse gases”, including carbon dioxide, methane(甲烷, 沼气) and water vapor.What do you think greenhouse
gases do?
They trap heat from the sun and therefore warm the earth.Glance quickly at the magazine article and answer the questions.
Who wrote the magazine article? What is the name of the magazine?
Sophie Armstrong wrote the magazine article.
The name of the magazine is Earth Care.What are the names of the three scientists mentioned in the article?
They are Dr. Janice Foster,
Charles Keeling and George
Hambley.3. What do they think about global
warming?
Do they agree with one another?
They don't agree with each other. Dr. Janice Foster
serious.
George Hambley
mild with few bad environmental consequences.

it is the burning of more and more fossil fuels that is resulting in a big increase in carbon dioxide.
What are the two graphs about?
Graph I shows the temperature increase of one degree Fahrenheit between 1860 to 2000.
Graph 2 is about the carbon dioxide content in the atmosphere, 1958--1990.What is the main topic of the
article?
Global warming/ the warming of
the earth. Answer keys for Ex.2 on Page 28:The first graph shows the global _______________ between ________ and __________. The temperature __________ and decreased over this period but on the whole it ________ _ by around one degree Fahrebhait. During this time, the earth reached its temperature in about
_________ and its highest in 2000. There was a steady _________________ in the temperature during the twenty years after 1980. We can see from the graph that the earth has become ___________ since early last century.temperature18602000increasedrose / went upincrease/risewarmerChecking answer – II (3m) lowest1910 Answer keys for Ex.2 on Page 28:The second graph shows the amount of ______________in the atmosphere from ________ to _______ .The carbon dioxide __________ steadily over this forty-year period.

The temperature last century didn’t increase much.
Everyone believes that global warming is caused by the activities of humans.
Janice Foster believes that global warming is caused b the burning fossil fuels.
Natural gas is a greenhouse gas.FFTF5. Carbon dioxide is a byproduct of burning fossil fuels.
6. People accept Charles Keeling’s data because he took accurate measurements.
7. Flooding could be one of the effects of future global warming.
8. George Hambley believes scientists are just guessing about the effects of global warming.TTTT9. George Hambley is worried about the effects of carbon dioxide on plant growth.
10. It is clear what the effects of global warming will be.FFChoices.1. Who found out the amount of carbon dioxide in the atmosphere from 1957 to 1977? A. Dr. Janice Foster. B. Charles Keeling. C. George Hambley. D. Sophie Armstrong.B〓〓〓〓〓〓〓〓〓 〓〓〓〓〓〓〓〓〓 〓〓〓〓〓〓〓〓〓 〓〓〓〓〓〓〓〓〓
