2. How has this come about?
3. What are the effects of global
warming?
Fast Reading1.Read the text fast and answer the questions.1. what is global warming?
2. How has this come about?
The earth is becoming warmer.①Human activity--- burning of fossil fuels.② Greenhouse effect--- greenhouse gases--- we need those gases.③ Huge quantities of extra carbon dioxide---from 1957 to 1997---from around 315 parts per million to around 370 parts per million.3.what are the effects of global warming?④ Encourage a greater range of animals.①The sea level to rise.② Severe storms, droughts, famines, the spread of diseases, and destruction of species.③ Make plants grow faster. Crops will produce more.2.Choices1. 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.2. "But there are some very different attitudes among scientists towards this issue.” "Issue" here means the same as the one in___ . A. I bought the new stamp the day of its issue. B. They are talking about one of the key issues in the election campaign. C. The government is expected to issue a statement about the election. D. The magazine has 12 issues each year.3. The author probably agrees that ________ A. actually global warming is good for man. B. we should do nothing about the global warming. C. catastrophes will happen if the globe keeps on warming. D. a lot remains to be found out about the effects of global warming.
3.Yes or no?1.Does Sophie Armstrong support a clear opinion?
2.Does George Hambley believe that we should worry much about the global warming?No. he doesn’t state it clearly.No, he doesn’t.
Second ReadingAnswer the questions on page 27Sophie Armstrong wrote the magazine article. The name of the magazine is “Earth care”2.What are the names of the three scientists mentioned in the article?They are DR.Janice, Foster,Charles Keeling and George Hambley1.Who write the magazine article? what is the name of the magazine?3.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 burning of more and more fossil fuels that is resulting in a big increase in carbon dioxide.4.What 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,1957-1997.5.What 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 not.
True or falseRead the article carefully and finish Part 2 on page 271.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 fuels. F F T F T6.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 be. T T T F F1. what is the purpose of the first paragraph?
To introduce the topic.To illustrate(阐述) points by providing evidence.2. What are the diagrams for?Third Reading 3. Why are there two quotes?
Because they are important or interesting points. Their aim is to attract your attention and to make you read them, and therefore to make you interested enough to read the whole 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 future. 4. What is the purpose of the last paragraph of the article? main ideaPart1 (para1)Introduce a debate over the issue of global warmingPart 2 (para2- 3)Part 3 (para4-8)Part 4 (para9)Illustrate how global warming comes aboutList two different attitudes among scientists towards global warmingIt’s up to readers to think and decide whether people should do sth about global warming or not 4 partsThe different ideas between Dr. Janice Foster & George Hambleygo upcatastrophe very seriouspositiveproducea greater range of animalsAssignment Prepare the language points of this passage and underline the important ones.
After remembering the vocabulary, do the exercise on Page 28.What are fossil fuels?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.
