必修3 Unit 4 Astronomy： the science of the stars 名词性从句
【本讲教育信息】一. 教学内容：名词性从句——主语从句与同位语从句二. 知识精讲：（一）主语从句1. 概念与引导词在复合句中充当主语的从句就叫做主语从句。
引导主语从句的连接词有that, whether, who, whom, whose, what, which, whoever, whatever, whichever, where , when , why , how Where we shall have the meeting makes no difference.我们在哪开会都无所谓。
That we were invited to a concert this evening is good news to us.我们被邀请去参加今晚的音乐会，这对于我们来说是个好消息。
2. 主语从句需要注意的问题（1）从属连词that在主语从句中不作任何成分，只起连接作用，但不能省略，并且可以用形式主语it代替，把that从句置于句末。
That he will come to the conference has excited every one of us.他要来参加会议使我们每一个人都很激动。
It is decided that the meeting will be put off till next Monday.已决定将会议推迟到下周一。
（2）主语从句常用it作形式主语，常用于以下固定句式中：①It +be +形容词（obvious, natural, surprising, wonderful, possible, likely, certain, necessary, important, strange…）+ that从句，在这类主语从句中，谓语部分常用虚拟语气，即should+动词原形。
It is necessary that one (should) master the skills of operating computers.掌握电脑操作技术是很有必要的。
Astronomy：thescienceofthestars教材分析
“理解”（Comprehending）部分通过五个练习题检测学生对本文核心内容的理解。练习1是对文章结构的分析以及大意的概括；练习2通过排序的方式帮助学生弄清本文的行文线索，也就是地球上生命的起源和发展历程；练习3提出5个小问题，考察学生的深层理解和推理判断能力；练习4让学生找出文章中出现的连接词，检查学生对文章中句型的熟悉和理解程度，同时还有助于学生在写作方面得到提高；练习5让学生回答问题并向全班学生汇报，开拓学生的思维并锻炼他们的语言表达能力。
“阅读”（Reading）讲述了地球上生命的起源。水的形成使得地球有别于其他星球，它使得地球上生命的诞生成为可能。科学家认为，地球上的生命首先诞生于水中，上百万年后，陆地上才长出绿色植物，随后出现了陆栖动物和水陆两栖动物。最初的动物靠孵化繁衍后代，后来出现了哺乳动物，人类也随之诞生了。文章最后讲了令人深省的问题：The earth may become too hot for the lives on it它关系到了地球的未来.
