Lesson 3 Thinking Skills and Reading Strategies
I. Material analysis
内容解读：
Thinking Skills：本部分为思维技能学习，内容为比较与对比，即抽取事物的共性，对比事物的差异，旨在培养学生的批判性思维能力。首先呈现思维技能的说明。学生借助文本和表格初步学习如何比较和对比相似事物的异同，其次，学生根据文本填写表格，巩固和内化所学。最后，学生根据Activity 2的内容讨论内行星和外行星的差异。本部分共有３个活动。
Reading Strategies：本部分为阅读策略学习，内容为引导学生通过归纳语篇的关键信息，判断信息间的异同和关联，推断信息间的逻辑关系。第一步，通过呈现阅读策略的要点及文本，学生初步学习如何寻找主旨句和支撑细节的关键句，构建概括文本大意的基础能力。第二步，学生再次阅读文本并概括文本大意，开展应用实践活动。第三步，学生通过阅读有关地球的文本内容进行练习，巩固阅读策略。本部分共有３个活动。
II. Teaching aims
通过本课的学习，学生能够：
1. 借助表格，运用比较和对比的思维技能了解太阳、地球等天体的特征，以及太阳系内行星和外行星的差异；
2. 识别文本主题句和关键句，提取文本的重要信息，并组织语言描述文本大意；
3. 根据表格谈论内行星和外行星的差异。
III. Teaching procedures
课时教学内容概述
本课时为思维技能和阅读策略的学习。 Thinking Skills部分是关于比较和对比思维技能的学习。Activity 1为学习理解类活动。学生通过阅读太阳与地球的相关文本及表格，培养提取关键信息与利用表格的能力，初步掌握对比和比较相似事物的方法。Activity 2为应用实践类活动。学生通过阅读文本，填写关于内行星和外行星的特征对比的表格，提升信息归纳与分类能力，明晰内行星和外行星的差异，巩固和内化Activity 1中所学思维技能。Activity 3为迁移创新类活动。学生两人一组，根据Activity 2的内容讨论内行星和外行星差异，深化对内行星和外行星差异的认知，熟练掌握所学思维技能。 Reading Strategies部分为概括文本大意这一阅读策略的学习，学生通过提取关键信息用自己的语言总结概括文本主旨大意。Activity 1要求学生通过阅读有关太阳重要性的文本，画出主题句和关键句，把握文本核心信息与重要细节。Activity 2要求学生通过再次阅读文本，完成总结概括，掌握总结概括文本内容的方法，加深对文本整体结构和内容的理解，初步学习阅读策略。Activity 3为话题迁移创新活动。学生通过阅读文本，画出重要信息，并据此完成总结概括，巩固从文本中提取关键信息并进行总结概括的阅读策略，培养筛选信息、归纳和概括的能力，以及运用英语准确表达关键内容的能力。

Thinking Skills: Comparing and contrasting
How to compare and contrast
Exercise 1 Read the text and complete the table.
The Earth is the largest rocky planet in our solar system. Its diameter is about 12,742 kilometers. From space, Earth looks blue and green because of its oceans, clouds, and green land areas. And the Earth is the only planet known to support life.
The Moon is much smaller than Earth. Its diameter is about 3,474 kilometers, about one-fourth the size of Earth. The Moon is gray with dark spots. No life exists on the Moon. Temperatures range from extremely hot during the day to freezing cold at night.
Object Size Diameter Color With life
Earth Yes
Moon smaller
Exercise 2 Read the text and answer the questions.
Mars is the fourth planet from the Sun. It is much smaller than Earth, with a diameter of about 6,779 kilometers. Its surface is covered with reddish rocks and dust. It has a thin atmosphere made mostly of carbon dioxide. The temperature on Mars can be as warm as 20°C in summer but drops to -80°C or lower at night. Mars is about 228 million kilometers away from the Sun.
Jupiter is the fifth planet from the Sun and the largest in our solar system. Its diameter is about 139,820 kilometers—11 times wider than Earth! Jupiter is a gas giant, made mostly of gas. The planet is very cold, with cloud-top temperatures around -145°C. Jupiter is much farther from the Sun, about 778 million kilometers away.
Object Group Elements Distance from the sun Temperature
Earth Yes
Moon smaller
Reading Strategies: Summarizing
Exercise :Read the text and complete the summary.
Protecting the Earth is very important. Here are three reasons.
First, the Earth gives us what we need to live. It gives us air to breathe and water to drink. It also gives us food and a place to live. Second, the Earth is home to many animals and plants. They need a clean and healthy environment to live too. Third, the Earth’s resources are less and less. Clean water, fresh air, and healthy soil won’t last forever if we waste them. Cutting down too many trees, polluting oceans, and burning fuels harm both nature and people.
The text mainly talks about _______________________.
In the text, we find _______________________, __________________________, and ______________________________.
2. Humans explore the universe for many reasons. First, we want to understand the universe and know what is out there in space. There are so many stars and planets. We want to see if there is life on other planets. Second, exploring the universe helps us learn more about science. We can learn about astronomy, physics, and other sciences. This knowledge can help us improve our lives on Earth. Third, exploring the universe can help us find new resources. These resources can be used to help people on Earth.
The text is mainly about why _______________________.
The main reasons are _______________________, __________________________, and ______________________________.
