  寫作話題

  20090530 Fossil fuels, such as coal, oil, natural gas, are used in

  many countries, but in some countries, the use of alternative sources of

  energy, including wind and solar power, are encouraged. Is this trend a

  positive or a negative development?

  關(guān)鍵詞解讀:記得在一部美國影片中:一位年輕人指著不遠(yuǎn)處的一個老頭,對其伙伴說:Hey , look at that fossil fuel. 這里的 fossil fuel 應(yīng)該是指“老不死”吧。還記得大學(xué)期間的一位教授說自己是old fossil,調(diào)侃自己是“老頑固”。那么這道雅思作文里的關(guān)鍵詞fossil fuel,指的是化石燃料,包括煤碳、石油、天然氣等在特定地

  質(zhì)條件下形成的沉積礦石。non-fossil fuel 指得就是非礦物燃料.

  例如:

  Gasoline(汽油), coal(煤), natural gas(天然氣), diesel(柴油),and other commodities derived from fossil fuels are non-renewable(自然資源非再生的). Unlike fossil fuels, a renewable resource(可再生資源)can have a sustainable yield(可持續(xù)發(fā)展).那么題中的另一關(guān)鍵詞 alternative sources(替代能源,新能源)
