Oceans Under Threat说课稿

一、教学内容

Oceans under Threat《新世纪高中英语》高中二年级第一学期第六课的课文。这是一篇科普类的说明文，主要介绍了海洋以及海洋生物所面临的威胁。文章以关键词作为小标题，分别从"overfishing" "threats to marine life" "pollution" 以及"possible solutions" 几个方面逐一介绍了海洋的现状。全文条理清晰，适于训练学生的阅读技巧与阅读速度。

二、教学重点、难点

1.了解海洋及海洋生物所面临的威胁。

2.提高学生的阅读兴趣。

3.通过抓住文章主题线索、摸清文章脉络，提高阅读速度，加强对文章的整体理解。

三、教学目标

知识:了解海洋及海洋生物所面临的威胁

技能：提高通过略读和跳读获取信息的能力

情感：意识到当前所面临的各种环境问题，树立较强的环保意识

四、教学步骤

1.Pre-reading

通过播放加勒比海海底世界的短片进行导入，给学生视觉的享受，对海底世界有了较为直观地了解，从而引发学生的好奇心，激发他们学习的兴趣，自然而然地把学生引入课文阅读的主题。

在导入过程中，利用学生已掌握的词汇以及已有的关于海洋的背景知识，进行问题设计，进一步激发学生的学习兴趣和学习积极性。

2.While-reading

整个while-reading分为三步

1) Skimming

让学生用skimming的方法快速快速熟悉课文的大致框架。通过skimming学生发现文章可以分为两部分：海洋所面临的问题以及可行的解决方法，其中所面临的问题是文章的主体。

2）Scanning

这一环节旨在具体的、快速的阅读和理解文章。

在了解了文章的大致框架后，让学生通过scanning进一步熟悉、细化重点内容。由于文章着重于海洋及海洋生物所面临的各种威胁，所以各个段落并不十分密切，所以逐段进行阅读和练习。通过这样的教学手法，可以教会学生如何处理一些较长的文章，避免读了后面忘了前面的内容，或者读完全文后对内容有印象但找不到具体段落。

3）Conclusion

在通过scanning对文章重点有了具体、细化的了解后，通过填表让学生对整篇文章有了一个清晰的脉络图，然后通过这张表格让学生自行进行全文的归纳总结，使学生真正做到自主学习。

3.Post-reading

在这一环节中，通过brainstorming和group discussion的形式，让学生意识到身边的一些环境污染问题，树立环保意识。
