　　The work by scientists from University of WisconsinMadison and the World Health Organization appeared in the journal Nature.Jonathan Patz,professor of the Gaylord Nelson Institute,led the study.He notes that climate scientists linked global warming to the heat that killed thousands of people in Europe in August of 2003.He says poor countries are least responsible for the warming,yet are most at risk from the health effects of higher temperatures.He says areas at greatest risk include Southern and Eastern Africa and coastlines along the Pacific and Indian Oceans.Also large cities experience what scientist call a “heat island” effect that can intensify conditions. Professor Patz says average temperatures worldwide have increased about onethird of a degree Celsius in the last thirty years,which can make a difference with the disease like malaria. 写作内容

　　答案:The text tells us that the global warming is getting more and more serious,which may influence the health of human beings and the rich countries should be responsible for the global warming. In order to keep our earth from getting warm,we should try to take all possible measures.Firstly，we should close factories which pollute air severely and improve their facilities.Secondly,we should try to control the production of cars and encourage people to take public vehicles to work.Thirdly,we should try to produce vehicles driven by solar power and other green energies.Meanwhile,we should strengthen the sense of protecting our planet and make necessary international laws to do with pollution problem.If we work hard together,we may manage to prevent our earth from getting warm. 祝 您 高考总复习·人教版·英语 选修 8 Unit 3
