课型 Reading and writing
教学内容 分析 unit 2 主要介绍太空的基本知识和人类探索太空所付出的努力。课文对于现在完成时的运用非常恰当，因为人类对太空的探索是一个从古至今持续不断的行为。本课文能够帮助学生充分理解现在完成时的语境，特别是对学习现在完成时有困难的学生有帮助。教师要通过观察、复述等方式引导学生形成对课文中现在完成时语句的深刻印象。
学情 分析 文章从描述太阳系开始，逐渐过渡到以外的星系，在陈述人类探索太空所取得的成就的同时也提出了困惑：地球之外是否还存在生命呢？因此，要充分调动学生的学习兴趣，精心设计教学活动，让学生更多地了解宇宙知识，以便能得到良好的收益，达到预期的效果。基于学生的实际情况，在课文教学时以语篇阅读的技能训练为主，训练学生对语段、语句之间的逻辑关系的理解。除此之外，还要引导学生关注语篇层面的信息，比如课文的逻辑叙述。例如：文章的第一段通过however引出主题，第二段用other和also实现了与第一句的衔接。
