       本课处于仁爱英语九年级（上）Unit4 Amazing Science Topic1 Spaceships Are Mainly Controlled By Computers第四课时，话题主要围绕谈论神舟五号和嫦娥一号进而涉及到电脑在航天中的应用。本话题从令人关注的神五入手，贴近生活，时代感强。然后，，由飞船的成功运行联想到电脑科技，最后，由电子邮件的发送与接收回到电脑的应用的实际生活中。教学中本着整合教材的精神，把本课的内容顺序进行调整，使之浑然成为一个整体，因为学生在学习本课前已经学习并掌握了部分关于谈论电脑科技的的句型，所以，教材的要求与学生现有的水平相一致。通过本课的学习，学生对祖国的科技有了更深的了解。更乐于接触现代科技:电脑、太空知识，口语表达能力和书面表达能力都会有所提高。
