Unit 6 课时4 Theme reading（课件）英语仁爱科普版八年级上册

该初中英语课件围绕太阳系主题，系统呈现太阳与八大行星的构成及行星特点（大小、距离、温度、生命可能性等），通过图片提问导入（如“太阳在太阳系中是什么”），结合Pre-reading的Pair Work讨论（如“我们居住在哪颗行星”），搭建认知支架，帮助学生激活已有知识，自然过渡到While-reading的文本学习。 其亮点在于融合语言能力（掌握planet等词汇、练习“smaller than”比较级结构）、思维品质（While-reading文本总结与分类图表、Post-reading表格填写及小组探究金星信息）和学习能力（分层Homework：背诵句子、绘制表格、短文写作），采用任务型教学（Pair/Group Work）与结构化Summary（分components和features）。学生能提升语言运用与科学认知，教师可借助清晰模块与可操作活动高效教学。

The amazing solar system Theme Reading Pre-reading Pair Work. Look at the picture and discuss the questions. A: Let's do Activity 1. Look at the solar system picture. Which planet do we live on? B: We live on Earth. It's the blue and white one, looks like our home. A: Right. Which planet is the largest? B: Jupiter! It's the big, striped one. Way bigger than the others. Pre-reading Pair Work. Look at the picture and discuss the questions. A: Yep. Which planet might have life? B: Maybe Mars? It looks a bit like Earth, and scientists are curious about it. A: Cool. Which planet is closest to the Sun? B: Mercury. It's the tiny one near the Sun. While-reading 03 While-reading Read the text and summarize the main idea. When you look up at the sky at night, you can see many stars. But do you know the Sun is a star too? Yes, it is the only one in the solar system. As a star, the Sun has eight planets around it, and Earth is one of them. 太阳系 While-reading Read the text and summarize the main idea. Among the eight planets, Earth is a middle-sized one, with a diameter of around 13,000 kilometers. Three of the planets are smaller than Earth. They are Mercury, Venus and Mars. The other four planets are larger. They are Jupiter, Saturn, Uranus and Neptune. In the solar system, Jupiter is the largest planet, with a diameter of about 140,000 kilometers. 行星 直径 While-reading Read the text and summarize the main idea. Mercury is the closest planet to the Sun, at a distance of about 58 million kilometers, while Neptune is the farthest, at a distance of about 4.5 billion kilometers. As for Earth, it is the third closest, closer than Mars but farther away than Venus and Mercury. Mercury and Venus are much hotter than Earth, while Jupiter, Uranus and Neptune are much colder. 距离，间距 While-reading Read the text and summarize the main idea. For example, the temperature on Neptune is around minus 200℃. No living things can survive on these planets. As our home, Earth is alive with life because it is neither too hot nor too cold. Mars is more similar to Earth in size and temperature. And there's also ice there! So scientists are looking for life on Mars. 生存，存活 While-reading Read the text and summarize the main idea.

Features：Known as the “evening star” or “morning star” as it's bright. Has a thick, toxic atmosphere mainly of carbon dioxide, causing a runaway greenhouse effect. Surface temperature is extremely high, around 462℃ on average, hot enough to melt lead. Rotates very slowly, and in the opposite direction to most planets. Venus Group work Summary 05 The amazing solar system Solar system components: Sun + eight planets Planet features: Size: Earth (middle - sized, diameter ~13,000 km); Jupiter (largest, ~140,000 km diameter) Distance from Sun: Mercury (closest); Neptune (farthest); Earth (third closest) Temperature: Mercury, Venus (hot); Jupiter, Uranus, Neptune (cold); Earth (moderate) Life possibility: Earth (has life); Mars (similar to Earth in size & temp., scientists exploring) Language points 06 1. Earth is a middle - sized one, with a diameter of around 13,000 kilometers. Three of the planets are smaller than Earth. “形容词比较级（如 smaller ） + than” 结构，用于对两个事物进行属性（像尺寸、温度等方面 ）比较，清晰展现出事物间的差异 。 eg: The moon is ______ (small) than Earth. And some stars are much ______ (big) than the sun. smaller bigger 2. Three of the planets are smaller than Earth. They are Mercury, Venus and Mars. The other four planets are larger. They are Jupiter, Saturn, Uranus and Neptune.” 通过 “Three...The other four...” 用于对太阳系行星的不同类别进行分组介绍。依据尺寸，将行星清晰划分为两组 （比地球小 & 比地球大 ）。 eg: ______ (Two) of the fruits are red. They are apples and strawberries. __________________ (The other three) are yellow. They are bananas, pears and lemons. Two The other three 07 Exercise Please choose the correct answer from A, B, C. 1. Which of the following is NOT a planet smaller than Earth? A. Mercury B. Venus C. Mars D. Jupiter 答案：D 解析：文中提到 “Three of the planets are smaller than Earth. They are Mercury, Venus and Mars.” ，说明比地球小的行星是水星（Mercury）、金星（Venus）、火星（Mars），而木星（Jupiter）是比地球大的行星，所以选 D 。 2. What's the position of Earth among the planets in terms of distance from the Sun? A. The closest B. The second closest C. The third closest D. The farthest 答案：C 解析：依据 “As for Earth, it is the third closest, closer than Mars but farther away than Venus and Mercury.” ，可知地球距离太阳是第三近的，所以选 C 。A 是水星的位置，B 是金星的位置，D 是海王星的位置，均不符合。 Please choose the correct answer from A, B, C. Assessment 07 Self-assessment I can acquire expressions related to team activities through watching and listening activities. I can share experiences of team activities in real - life contexts. I can understand and recognize the importance of collaborative cooperation in team activities. 08 Homework Basic (基础) 背诵文本中关于太阳系行星特点（大小、距离、温度等 ）的重点句子。 Improving(提升) Extend (拓展) 仿照 Activity 4，自己绘制表格，并分享给同学们。 以 “My dream trip to a planet” 为题，写一篇小短文，80-100词。 Blues 135554.8 $$
