Unit 4 Space exploration单元分析本单元主题:人与自然——宇宙探索单元内容分析本单元围绕“太空探索”这一主题展开,内容涉及人类探索太空的历史与成就(包括我国航天事业的发展和成就)宇航员的选拔、太空中的生活、火星探索计划、天文百科知识,以及关于“人类耗费时间和金钱去探索太空是否值得”这一话题的会科学家以及宇航员们为航空航天事业的发展不断努力、勇于开拓的精神,从而激励青少年勤奋学习、刻苦钻研、不畏挫折,努力探索自己的发展道路,立下远大志向,为国家科技事业的发展奉献自己的智慧和力量。
以下为教材各部分教学内容简要分析及教学活动实施建议:1.Opening Page开篇页的主题图展示了2019年1月3日“玉兔二号”(即嫦娥四号月球车)与嫦娥四号着陆器分离后驶抵月球表面的画面。
嫦娥四号首次实现在月球背面着陆,是中国航天事业发展的一座里程碑,是值得每个中国人铭记的时刻。
这一图片不仅能够增强学生的民族自豪感,还能激发学生讨论的热情,让他们能够很快投入到本单元的学习中去。
本单元的名言警句是“Mystery creates wonder and wonder is the basis of man's desire to understand.-Neil Armstrong”这是第一位登上月球的美国宇航员尼尔·阿姆斯特朗的名言:“神秘感激发好奇心,而好奇心则是人们探索未知事物的前提。
”人类太空探索的原始动机主要源于与生俱来的好奇心,而这种好奇心和求知欲也是推动人类发展的巨大动力。
太空探索的成就背后是人类不断进取的精神,而只有将这种精神延续下去,人类才能突破极限,走向广阔的宇宙。
2.Listening and Speaking:Talk about how to become an astronaut 本部分的主题是“谈论如何成为一名宇航员”。
关于探索太空的奥秘,能够获得最直接感受的非宇航员莫属,因此,宇航员这一职业对于青少年而言充满了魅力,既带着神秘感,又带着使命感。
