  2. take off Global Warming All scientists agree with the view that it is human activity that has caused global warming. For example, fossil fuels are used , releasing lots of CO2 into the atmosphere. As a result, more heat energy is possible to be trapped, causing the global temperature to increase. subscribe to consumed quantities of tends go up

  3. Graph description • General trend • Detailed information Time & Data • We know that the levels of carbon dioxide have increased greatly over the last 100 to 150 years. • He found that, between these years, the carbon dioxide content of the atmosphere went up from around 315 parts per million to around 370 parts per million. increased went up

  4. Graph description • increase • go ___ • r_____ • c_____ up ise limb 1. General trend The global average temperature is i_________ steadily. 2. Detailed information Between ______ to ______, the global average temperature went up from ______to _____ Fahrenheit. increasing 1860 2000 -0.5 0.5

  5. Graph description 1.General trend 2.Detailed information 3.Conclusion Graph 2: The content of CO2 in the atmosphere is rising. Graph 1: The temperature is increasing. Conclusion: The rise of the content of CO2 in the atmosphere _____ the increase of the temperature. results inresults fromleads to gives rise to

  6. Graph description 1.General trend 2.Detailed information 3.Conclusion 1. The rise of the content of CO2 in the atmosphere results in the increase of the temperature. 2. It is the rise of the content of CO2 in the atmosphere that results in the increase of the temperature. Tip: to emphasize a certain part: it is…that…

  7. Different attitudes Tip: to present one’s opinion: different words On the one hand, Dr Foster holds a NEGATIVE attitude. • Dr Fosterexplains over the next 100 years the amount of warming could reach 1 to 1.5 degrees Celsius, but it could rise to 5 degrees. • Dr Fosterexplainsany trend in which the temperature increases by 5 degrees would lead to a disaster. • Dr Fosterexplainsthere may be a rise of the sea level, the spread of diseases and even extreme weather. • Dr Foster explains“Though we can’t know exactly what effect global warming will have on the climate, it is possible to be serious.” says thinks catastrophe sudden, widespread and serious a_____ grees severe storms, floods, droughts p______ redicts “We can't predict the climate well enough to know what to expect. It could be serious.” subscribes to ___________ the view that…

  8. Different attitudes Tip: to make the opinion convincing: supporting details On the other hand, George Hambleystates that more CO2 is a positive thing: 1. It will make plants grow quicker. 2. Crops will produce more. 3. It will encourage a greater range of animals. A. The health of the patient was in a recovery state. B. The USA is made up of 50 states. C. His father used to work in a state-owned company. D.

  9. It can be inferred fromthe last paragraph that the author’s attitude towards global warming is _______. A. positive B. negative C. neutral(中立) D. unknown • Does that mean we should do nothing? • Or, are the risks too great? • Or, are the risks of doing nothing too great?

  10. At least 11 islands are now disappearing as a result of Sea Levels Rise and one of them is Maldives(马尔代夫). • Many residents (居民) in Maldives have been moving.

  11. The decrease of the number of residents • decrease • go _____ • d_____ • f_____ down 2000 rop all detailed information general trend The graph shows the changes of residents of Maldives. On the whole, the number __________ steadily over this period, from ______ in the year _____ to more than ______ in the year _____. It can be concluded that it is the rising global temperaturethat ___________________________ _____________________. decreased 20,000 1995 2,000 2004 has resulted in the decrease of the number of residents conclusion

  12. Speech Ladies and gentlemen, I’m a resident in Maldives. When we talk about global warming, we are talking about the world of tomorrow. In a changing world, we need to be changers. And here are some suggestions: 1. (laws) … 2. (transportation) … 3. (environment) … In conclusion, don’t forget: We didn’t inherit(继承) this planet from our parents. We borrow it from our children. Thank you! Slogan 口号

  13. Empty words contain nothing but CO2. • It is human activities that really matter!
