Global warmingWhat is it in the picture?
What is it used for?
How does it work ?
First reading:
1.What is the purpose of the first Para?
2.What are the diagrams for?
3.What is the purpose of the last paragraph of the article?
1.What is the purpose of the first Para?
To introduce the topic2.What are the diagrams for?
To illustrate points by providing evidence3.What is the purpose of the last paragraph of the article?It functions as a conclusion by asking the reader to reflect on the major theme of the text and to predict what might happen in the futureWhy are there two quotes?Because they are important or interesting points. Their aim is to attract your attention and make you read them and therefore to make you interested enough to read the whole articleMain idea ofeach partWriting techniquesRaising a questionGiving examples,using graphs,explanationGivingexamples,
making contrastUsing a question,leaving
readers to think over the issuePart 1.paragraph1
Part 2: Paragraph2--4
Part 3: Paragraph5--10Part 4:
Paragraph 11
Main Idea:
Part 1. Introduce a debate over the issue of global warming
Part 2: Illustrate how global warming comes about
Part 3: List two different attitudes among scientists towards global warming
Part 4. It’s up to readers to think and decide whether people should do sth about global warming or not
ComprehendingWho write the magazine article?
what is the name of the magazine?Sophie Armstrong wrote the magazine article.The name of the magazine is Earth careWhat are the names of the three scientists mentioned in the article?They are DR.Janice, Foster,Charles Keeling and George hambley3.What do they think about global warming? Do they agree with one another?They don’t agree with each other.
DR.Janice Foster thinks the effects of global warming could be very serious
George Hambley thinks global warming will be mild with few bad environment consequences
Charles Keeling believes it is the buring of more and more fossil fuels that is resulting in a big increase in carbon dioxideWhat are the two graphs about?Graph 1 is about the temperature difference from long-term average,1860---2000
Graph 2.is about the carbon dioxide content in the atmosphere,1957--1997What is the main topic of the article?It is up to readers to think and decide whether people should do something about global warming or notTrue or false1.The temperature last century didn’t increase much
2.Everyone believes that global warming is caused by the activities of humans
3.Janice Foster believes that global warming is caused by burning fossil fuels
4.Nature gas is a greenhouse gas
5.Carbon dioxide is a byproduct of
burning fossil fuels6.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
9.George Hambley is worried about the effects of carbon dioxide on plant growth
10.It is clear what the effects of global warming will beUsing about Language1.Data ,kept on
