【英语时差8,16】陨星（上）

（单词翻译）

You’re out on a clear, starry¹ night with your best friend, looking for shooting stars. Look, there’s one! your friend shouts. But by the time you look, it’s gone. There’s another! she cries. Too late; you missed it. Then one comes along that seems to just amble² across the sky, nice and slow. Why is it that some shooting stars are so fast and others are much slower? Well, there are a few reasons. Shooting stars are actually small meteors. Meteors are essentially³ icy rocks that come from space and burn up from the friction⁴ of entering our atmosphere. A very small rock will burn up quickly and be gone almost before you can see it. A larger rock will take a while, and leave a long, bright streak⁵ in the sky.
