(Line 6)②All scientists subscribe to the view that the increase in the earth’s temperature is due t o theburning of fossil fuels like coal, natural gas and oil to produce energy. (Line 18)③This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and watervapour, trap heat from the sun and therefore warm the earth.(Line 26-29)VI. Teaching aids:Multimedia classroom, printed materialVII. Teaching methods:Task-based teaching, communicative teaching methodVIII.Teaching procedures:Step 1.

Graph 2 shows the carbon dioxide content in the air increased by 70 parts per million from1957 to 1997.D. The more CO2, the higher temperature.(3) Which of the following statements is TRUE? (★★★)A. All scientists disagree that global warming mainly results from the burning of fossil fuels.B. When people burn fossil fuels, the most important “greenhouse” gases--methane (甲烷)will be given out.C. Too much greenhouse gases trap heat from the sun and therefore the earth is warmer.D. Greenhouse effect does no good to the earth at all.【意图说明】转述原文中重要的但却有难度的句子降低学生阅读理解的难度，同时也强化本文的重点，即全球变暖是如何形成的；在讲解的过程中会适度拓展，让学生明白一些长难句的句子结构和意思。
