听一分钟英文：Solar System-太阳系

The Solar System is an amazing thing. I can’t imagine just how big it is. I don’t think anyone can. It all centres around our Sun. Our solar system has eight planets in it. When I was a kid I learnt there were nine planets, but some time ago, scientists decided¹ Pluto² wasn’t a planet. All of the names of the planets in our solar system are really cool. Everybody knows the names because they are used every day in advertising³ or to name cars and things. Pluto was even the name of a Disney character. I think Saturn⁴ is the name of a car and Mercury is the name of a radio station. I love looking at photos of the solar system. They get more beautiful as our technology gets better. One day we’ll go on solar system tours.
