14、st beautiful one in the world. 本案例是根據(jù)九年級全一冊Unit13 pre-read 拓展而成的。1 本文所設(shè)計(jì)的問題實(shí)際上是英語課與生物課中的“環(huán)?！闭鹿?jié)的整合。教師讓學(xué)生列舉污染源，學(xué)生講出了很多的污染源 - 空氣污染、水污染、土壤污染、噪音污染等等。實(shí)際上讓學(xué)生復(fù)習(xí)了生物課中剛學(xué)的“大氣與健康”、“土壤與健康”、“水與健康”等的環(huán)保知識。2. 教師讓學(xué)生分組討論如何解決這些污染問題，巧妙地運(yùn)用了合作學(xué)習(xí)法，不但培養(yǎng)了學(xué)生探究問題和自主解決問題的能力，而且也培養(yǎng)了學(xué)生的參政議政的意識。 同學(xué)們以主人翁的身份，提出了種種解決方法。解決水污染問題，他們先用勸說的辦法，當(dāng)此法行不通時(shí)，再借助新聞媒體的力量，最后，上告政府；解決空氣污染問題，他們號召人們騎車上班。當(dāng)老師提醒他們，若家離工作地方很遠(yuǎn)，不能騎車上班時(shí)，該怎么辦？他們馬上想到了公交車。他們要求政府增加公交車輛，建造地鐵。3. 老師因勢利導(dǎo)，請他們回憶一下，以前有否做過有損于環(huán)保的事情。其實(shí)是英語課與政治課的整合。在這么和諧，民主、激動(dòng)的氣氛中，同學(xué)們毫無顧忌，
