Unit1 Using Language2 名师教学设计
Teaching analysis
该板块的活动主题为“写一写伟大科学家的必备素养”（Write about what makes a great scientist）。该板块有两个阅读语篇，分别题为“The Father of China’s Aerospace”“A World of Pure Thought”。它们从不同角度简要叙述了科学家钱学森和史蒂芬霍金的经历、重要贡献、性格特点以及他们所具备的科学素养。在写作策略和技巧上，两个语篇都有效使用了一些衔接词语，如：however、nevertheless、because、in general、besides、furthermore、above all等。关注语篇的衔接和连贯是对学生写作能力的较高要求。阅读文本中的范例有助于学生领会、体验衔接词语的意义和作用，为他们接下来完成写作任务提供指导。考虑到文本的长度以及阅读难度，笔者设计了两个课时。
