13、countries who are to blame for producing most of the carbon dioxide.2021/8/8 星期日26A sample discussionSa:I agree with Li Bin.It is the developed countries that put most of the carbon dioxide into the air,so the developed countries are really the ones to blame and to pay for that.2021/8/8 星期日27Sb:Well

14、,Im afraid I disagree with you.Professor Chen is right.Whatever we do,we have to do it as a global community.Developed and developing countries should work together to improve the environment.2021/8/8 星期日28Sc:I hold the same viewpoint as Li Bin.In developed countries people are producing a large amo

22、nd power?CHEN:Im afraid not.Its not that simple.Renewable energy is not concentrated enough.2021/8/8 星期日39 And you need huge areas of land to produce large quantities.Its just not possible-not with the technology we have at present anyway.2021/8/8 星期日40LI BIN:What about nuclear power?Thats a good so

23、urce of energy.CHEN:Yes,I agree.Its concentrated and doesnt produce carbon dioxide but there is a limited amount of uranium-the material you need to make nuclear power.2021/8/8 星期日41 And many people dont like it because of past accidents-like the one at Chernobyl.LI BIN:So what can we do?2021/8/8 星期

24、日42CHEN:Well,we need to find ways of using fossil fuels that dont put carbon dioxide into the air.And we need to produce more products that use less energy.It would also help a little if individuals cut down on the energy they used.2021/8/8 星期日43LI BIN:But,sometime in the future,well need new techno

25、logies that will replace fossil fuels.CHEN:Exactly.However,whatever we do,we have to do it as a global community.That means developed and developing countries will have to work together.2021/8/8 星期日44LI BIN:But its not the developing countries who put most of the carbon dioxide into the air.The deve

26、loped countries are really the ones to blame.2021/8/8 星期日45CHEN:Yes,thats true.But,we still have to work together because global warming is going to affect everyone.If our children and our childrens children are to have a good future,we must ALL look after this planet.2021/8/8 星期日46Homework 1.Review
