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:
YuanLongpingisknownasChina’s“fatherofhybridrice”.It’ssaidthatinChina,weeatdependingon“TwoPing”----DengXiaoping,whomadethepolicyofSystemofProductionResponsibility,YuanLongping,whoinventedhybridrice.

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。

5.错的人是我。ItisIwhoamwrong.
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。
