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.

Unit 1 Friendship 第四课时

一名优秀负责的教师就要对每一位学生尽职尽责，作为高中教师就要精心准备好合适的教案。教案可以让学生更好的消化课堂内容，减轻高中教师们在教学时的教学压力。关于好的高中教案要怎么样去写呢？急您所急，小编为朋友们了收集和编辑了“Unit 1 Friendship 第四课时”，供大家借鉴和使用，希望大家分享！

Usingstructures

第一步：学生独立以快速阅读的方式完成这部分的阅读理解和课后练习;

第二步：两人活动，根据上一节课学习的直接引语和间接引语之间转换的规则复述故事。（为了培养学生的逻辑思维和表达的连贯性，教师可以鼓励学生在第一步快速阅读的时候列出文章的关键词，如：arrive；goupstairs；startclearup；sleepatnight；...etc.然后根据关键词来重组故事情节。应该尽量避免照本宣科地复述）

Readingtask(Page44)

第一步：阅读练习册中ReadingTask中的短文“FriendshipinHawaii”，理解其大意；

第二步：完成课后设计的配套练习（Page45:Exercise1and2），通过练习巩固对课文内容的理解；（在练习二中有部分问题的设计显得有些抽象模糊，不利于学生思考，如：HowdopeopleinHawaiigetonwithoneanother?HowcanpeopleinHawaiiliveinpeace?教师在实际教学的过程中可根据具体情况选择忽略或做适当的改动，使问题更为明确）

第三步：全班活动，比较中国和Hawaii对待友情的特点和方式（如果学生程度较好，可将话题拓展到比较东、西方文化中对待友谊的差异）；

第四步：要求学生将比较结果用一段话表达出来；

第五步：如果时间允许，可让学生根据讨论得出的结论模拟表演不同地区，不同文化中朋友们见面的接待方式，活跃课堂气氛;

Homework:

布置一篇描述友谊的作文让学生课后完成，作文的题材和具体内容不要过分限制，要鼓励学生锻炼创造性思维。（也可以将该写作练习设计成一个小游戏：先让学生完成一篇描写自己好朋友的小作文，但对象要限制在班级以内，120字左右，并在下次上课是在课堂上选读2-3篇文章，让学生猜测文中的主人公是班上的哪位同学，教师可适当准备一些小奖品作为奖励）
