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。
这个教学过程分三个步骤：pre-reading,reading,discussion,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一些著名的科学家，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；细读(extractivereading)，即加深对课文理解。培养学生的分析和逻辑推理的能力，并帮助学生对文中的难句进行句子结构的分析。
discussion:教师开展课堂小组讨论，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。
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。
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。
