Skim the text to get the main idea of the passage and each paragraph, then divide the whole passage into 4 parts and summarise the main idea of each part.
Main ideas of each partPart1
(1)Introduce a debate over the issue of global warmingPart2
(2-3)Explanation about how global warming comes about.Part3
(4-6)Analysis of data and two different attitudes among scientists towards global warming.Part4
(7)Two choices of dealing with this problem.How has the global warming come about?
Para2—3①Human 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.Does global warming matter?Positive effects Negative effects cause the sea level to rise
severe storms
floods
droughts
famines
the spread of diseases
disappearance of speciesPositive effects Negative effects make plants grow quicker
crops will produce more
a greater range of animals
make life betterTrue or false?
1. The temperature in the last century did not seem to increase much.
2. Everyone believes that global warming is caused by the activities of humans.
3. Janice Foster believes that she can measure the future global rise in temperature.TTF4. The rise in carbon dioxide is causing
a steady increase in global warming.
5. George Hambley believes that global
warming will do good rather than
harm to the earth.
6. It is clear what the effects of global
warming will be.TTFWhat is the purpose of the P1?
To introduce the topic.
What is the purpose of the last paragraph?
---- 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.
A : We shall do something about global warming.B: We shall do nothing about global warming.DebateGlobal warming has attracted the world’s attention, because it affects us and will affect our later generations. Even though we are not sure about the effects of global warming, we should still hope for the best,
prepare for the worst.Summary
