教案点评:
根据新教材中的以阅读为主的教学环节所设计的一课时/两课时教案。本课阅读课的目的是让学生通过阅读英语材料,掌握实验步骤,领悟严谨的科学精神财富,体验英语语言、问题,学习灵活使用语言结构。
这个教学过程主要分四个教学步骤:pre-reading,reading,post-reading,languagepoints。
pre-reading:在阅读课文之前,教师可适当的讲解与本单元有关的背景知识,运用图片向学生介绍传统农业与现代农业的差异,通过提问的方式引入课文主题。教师可根据课文的内容和篇章结构,从不同的角度,引导学生对课文内容进行预测和讨论。
reading:课文分三个步骤:掠读(skimming),即带着某个问题进行搜索式阅读,这样能培养学生捕捉关键句的能力;略读(skipping),即教师指导学生通读全文,理解课文大意,培养学生发现文章或段落的主题句及概括大意的能力;听读(listening),即加深对课文理解。
post-reading:教师通过让学生完成课堂练习,加深学生对课文内容的理解。教师开展课堂小组活动,诱发学生的参与积极性,培养学生辩证的看待事物的能力,锻炼他们说话的条理性和逻辑性。
languagepoints:教师点评课文中的知识点。
通过以上个步骤的训练,学生对课文理解得比较深刻,同时也掌握了文中的语言知识。

袁隆平人物简历
袁隆平被誉为中国的“杂交水稻之父”.中国农民说,吃饭靠“两平”,一靠邓小平----制定了生产承包责任制的政策,二靠袁隆平----发明了杂交水稻。
袁隆平,男,1930年9月出生于北京,1953年毕业于西南农学院农学系。毕业后,一直从事农业教育及杂交水稻研究。
在中国人民正闹饥荒的20世纪60年代,袁隆平提出了杂交水稻的概念,这种新型水稻具有高产量的特点。10年后,他研制成功了一种产量比一般水稻高出20%的新型水稻。
袁隆平一生献身于农业研究,先后受到联合国教科文组织、粮农组织的称誉。袁隆平虽已年届70岁,仍然一如既往地从事农业研究。
Newwords:杂交水稻hybridrice;生产承包责任制SystemofProductionResponsibility;学院institute;闹饥荒sufferthefamine;产量yield;联合国教科文组织UNESCO,粮农组织FAO.
Possibleversion:

4.note:
a.在强调句型中,若被强调部分指人,可以用关系代词who或that;若被强调的是状语,只能用that,不能用when或where。
b.注意与“Itis/was…that+clause”主语从句的区别。
强调句型与it作形式主语,that从句作真正主语十分相似,但主语从句中Itis/was后通常用名词或形容词作表语。强调句型中Itis/was后是对主语、宾语或状语的强调成分。

Unit 4 Earthquakes第二课时


Reading

第一步:预读,教师事先设计导读性问题,要求学生通过解读标题和插图,阅读文章的开头和结尾,在最短的时间内作答,然后用三两句话概括大意。

Question1(canrefertoP67Speakingtask)

Youaretochooseeightthingstoputintoyourpersonalearthquakebag.Whatarethey?

Question2(thesignbeforeanearthquake)

Canyoudescribethepicturesinpre-readingindetails?

Question3DoyouknowanythingaboutTangshanEarthquake?

第二步:略读,要求学生全文通读,忽略不懂的生词,但是要求分辨出各个段落的大概意思。然后完成课后的第三题。

Mainideas

1.Whathappenedbeforetheearthquake.

2.TheearthquakedestroyedthecityofTangshanandshockedthepeople.

3.Thedamagesoftheearthquake

4.Thearmycametohelpthesurvivors,bringinghopeforanewlife.

第三步:在详细阅读之前提示关于唐山大地震的背景:struckat3.42am.onjuly28,1976;7.8magnitude;epicenterwas11kmbelowthecityofTangshan;242419peoplekilled;economicdamageofthoseburiedintherubblewererescued;injuriesfromtheearthquakecaused2.200peopletobecomeparaplegics.

第四步:要求学生边读边完成课后的第一题,第二题。其中,第一题连接句子不但是对课文内容的考察,也是对英语句子逻辑性和语法的一个联系,在学生回答的事情应该引导他们注意这两点。

另外,教师可以设计一些需要查找的信息和具体事实的问题或任务:

要求学生带着问题快速浏览文章,从阅读材料中,迅速查找这些特定的信息和具体的事实。

第五步:要求学生运用语境猜测词的意思,把不认识的单词用简单的语句表述出来,分组讨论学习黑体字单词及词组的意思和用法。
