新人教高中英语必修三Unit4Space exploration单元分析讲义
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。

（不定式短语to enter space作定语，修饰the first person）［P40］②However, while such disasters brought much sadness and disappointment, the desire to explore the universe did not die.然而，尽管这样的灾难带来了很多悲伤和沮丧，但对探索宇宙的渴望没有消失。
（不定式短语to explore the universe 作后置定语，修饰desire）［P41］不定式作定语一般情况下置于所修饰词的后面，并且与被修饰的词之间构成一定的逻辑关系。
①主谓关系被修饰词是不定式动作的发出者。
He's always the first person of the team to put forward the solution to the problem.他总是团队里第一个提出问题的解决方案的人。
2动宾关系被修饰词是不定式动作的承受者。
She looked for some interesting novels to read.她找了一些有趣的小说来读。
特别注意当“不及物动词的不定式＋介词”作定语时，该短语与其所修饰的词之间为动宾关系，此处的介词不可省略。
He can find no one to talk with.他找不到可以交谈的人。
③部分抽象名词后常接不定式作后置定语。
