  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

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.

  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.
