语文必修三第四单元导学案【学习目标】知识目标：了解相关文体、字词能力目标：培养删选信息的能力情感目标：培养对科学的兴趣与热爱一、文体知识1、【说明文的概念】说明文是以说明为主要表达方式来解说事物、阐明事理而给人知识的文章体裁。

它通过揭示概念来说明事物特征、本质及其规律性。

说明文一般介绍事物的形状、构造、类别、关系、功能，解释事物的原理、含义、特点、演变等。

说明文实用性很强，它包括广告、说明书、提要、提示、规则、章程、解说词、科学小品等。

【说明文的语言特点】准确、简洁、平实是说明文语言的主要特点。

当然，说明文的语言风格也是多种多样、各有特色的，有的以平实见长，有的以生动活泼见长。

以此为据，可概括为平实说明和生动说明两种方式。

一般来说，以说明事物为主的说明文，重在抓住事物的特点，用简明的语言平实地加以说明。

而科学小品，讲究趣味性、文艺性，须要作必要的生动、形象的说明。

【说明方法】①举例子。

使文章更加具体，更有说服力，更客观地说明了事物。

使比较抽象，复杂的事情或事物变得通俗易懂，让人信服。

举例子必须让人觉得有真实感。

②.打比方。

说明某些抽象的或者是人们比较陌生的事物，可以用具体的或者大家已经熟悉的事物和它比较，使读者通过比较得到具体而鲜明的印象。

增强说明的形象性和生动性的说明方法叫做打比方。

说明文中的打比方，同修辞方法中的比喻是一致的。

用这个方法，可以把抽象复杂的事物说得浅显易懂，具体生动。

不同的是，比喻修辞有明喻、暗喻、和借喻，而说明多用明喻和暗喻，借喻则不宜使用。

（把……比作……，体现了……的……特点……）③下定义。

用简明的语言对某一概念的本质特征作规定性的说明叫下定义。

从而更科学、更本质、更概括地揭示事物的特征/事理。

下定义能准确揭示事物的本质，是科技说明文常用的方法。

④列图表。

为了把复杂的事物说清楚，还可以采用图表法，来弥补单用文字表达的缺欠，对有些事物解说更直接、更具体。

使读者直观，一目了然地了解事物的特征。

2019-2020学年高中英语人教版必修三Unit 4 Astronomy: the science of the stars Ｉ．单元教学目标II．目标语言III．教材分析与教材重组1. 教材分析本单元以astronomy: the science of the stars, the development of life, space travel and gravity为话题，通过本单元的几篇阅读材料使学生对以上问题有所了解，并通过文章中的一些探讨性的问题，比如，The earth may become too hot for the lives on it. Then what will our future be? 使学生更好地了解我们的地球和我们的生活环境，并引发对“地球的将来如何”的热烈讨论，通过这些讨论激发学生对天文学了解和探究的强烈兴趣。

通过讨论登月球需要的物品和可能遇到的困难学会提出问题和解决问题的表达方法，并能就此写出一篇表达合理思路清晰的短文。

1.1 WARMING UP以讨论的形式通过三组问题引导学生讨论边缘科学，讨论科学的方法以及要成为真正的科学家所必须掌握的技能。

1.2 PRE-READING 主要让学生弄清楚什么是科学思想，什么是宗教信仰或文化传统。

在探讨生命起源的科学道理之前，让学生以听故事或讲故事的方式，交流有关宇宙的起源的种种传说，既有趣味性，又能调动学生的相关知识，激活学生的思维。

1.3 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.1.4 COMPREHENDING通过四个选择填空题检测学生对本文核心问题的理解：地球上生命的起源和延续需要哪些条件？随后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。
