【学情分析】
大部分学生基础较弱，运用英语进行交际的能力较差，所以在文章阅读上设置思考递进式的问题一步步引导学生阅读，激发他们的学习热情，使学生的学习思想从“被动接受型”慢慢向“自主学习型”转变。也有部分基础较好，学习能力较强，学习动机较稳定的同学，这部分同学鼓励他们参与稍难点的题目。让他们学习思维的逻辑性和创造性逐步提高。基于学生学习水平的不同，恰当的采取因材施教的方法进行教学。
基于以上原则，首先在问题设置上，采取循序渐进的方式，难易问题活动适量，让更多的学生积极参与进来。其次，小组讨论，同伴合作，激发全体参与到课堂中，同时增强了同学们之间的凝聚力。最后，模拟访问形式，让学生既巩固学习了本课内容，同时使学生的情感态度和价值观的得到升华。让学生在愉快学习的环境中锻炼英语语言表达能力，理解个人的发展和价值的实现要与社会和国家发展的需要相结合。
【效果分析】

本节课体现了《新课标》的要求，面向全体学生，教师转变在教学中的角，成为学生的引导者，引导学生自主、探究、合作学习，使学生真正成为学习的主体。教学目标、重难点明确，注重联系学生生活实际创设真实的语言环境。
【二】注重引导学生阅读技巧，形成有效的学习策略。
在文章阅读上采取略读、扫读、预测的方式让学生理解文章大意。在细读过程中读，跳读，段落填空的方式精准阅读，掌握重要词汇和语法。
【三】开展协作活动，调动学生课堂参与热情。
为了让学生更充分的了解袁隆平的概况，本课导入部分从中国诗歌，古代农学家入手，以微课堂的方式导入，再穿插袁隆平的相关视频，一下点燃学生学习的热情，再通过一些图片和问题，让学生在教师的引导下讲出相关知识。在阅读过程中也创设多种活动任务。学生小组，同伴协作形成组组之间，同伴之间的抢答意识。最后以采访袁隆平的情境设置环节结束本课的总结升华环节，激活学生的思维，培养了他们发散思维能力。整个教学过程
成为学生主动吸收和输送信息的学习过程。
