Do you know what the Sun is in the solar system The Sun is a star! It's the only star in our solar system. And as a star, it has eight planets around it. Earth is one of them. Pair Work. Look at the picture and discuss the questions. 1. Which planet do we live on 2. Which planet is the largest 3. Which planet do you think might have life 4. Which planet is the closest to the Sun The earth Mars Jupiter Mercury Pre-reading Activity 1 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. 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. Pair Work 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 Activity 2 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 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 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 Read the text and summarize the main idea. Summary: The text mainly talks about in the solar system. In the text, we can find most of the planets are very Earth, while Mars may be similar to Earth in ... ...
