层次分析式

对于结构严谨,层次分明,论点突出,论据充分且长句、难句较多的课文

(多为议论文和说明文)可用此法。

例如教学课文 “Pollution”(高中英语课文第一册第十二课)。

Pollution 这篇课文,可分为三个层次,依次输入:

  1. Introduction(paragraph I)

The population of the earth is increasing very fast. Agriculture andindustry are developing rapidly.

  1. Development(Paragraph Ⅱ)

①the definition of pollution

②sources of pollution

a: agriculture: farmers add fertilizer and spray poison b: industry: factories Produce Waste and Poisonous gases

c: transport Waste gases from cars and trucks

d: daily life: rubbish thrown away by millions of people;noises from airplanes and factories

③the danger of pollution a: do harm to human health

b: kill trees and vegetables

①way to get rid of pollution a: recycle waste materials

b: make waste water clean

c: prevent factories from sending out poisonous gases and polluted water

  1. Conclusion(paragraphⅢ)

The battle against pollution won’t be won until every one knows its seriousness and does something to stop it.

这种方法把课文内容作为整体信息向学生输入,可以加深学生对课文意思的理解,有利于训练学生对篇章结构分析的能力和发展学生逻辑思维能力,使学生的阅读能力得以发展和提高。

总之,课文教学的全过程,是由整体到局部,再由局部到整体,由粗到精,由浅入深,由领会到表达,逐层深入的过程。好的开端是成功的一半。课文教学中,文章信息的整体输入搞好了,无疑对后面的课文教学会起到事半功倍的作用。教学实践使我们认识到,英语课文教学中,文章信息的整体输入,是一项科学性与艺术性相结合的活动,既要符合语音教学的规律,又要从教材的实际出发,采用灵活多样的方法,做到形式和内容的尽可能统一。只要我们不断探索,不断提高与改进,才能臻于完善。
