What's That in the Sky?

What's That in the Sky? My sister and l love to learn about all the beautifu things in outer space. What is outer space?Well, it's the space beyond the earth's atmosphere. Last night, we went outside to watch the night sky. Wow! Every minute, there was a bright flash of light in the sky. Sometimes the light had a really long tail. I felt like I was watching a fireworks show—only it was made by nature. What were we seeing?Meteors. We sometimes call meteors" shooting stars" . But they are not stars. They are pieces of dirt and rock from outer space. Some are the size of a small grain of sand. But they make a big show when they enter the earth's atmosphere.

天上的东西是什么? 我姐姐和我喜欢了解外太空的所有美丽的东西。什么是外太空?嗯，那是地球大气层之外的空间。 昨天晚上，我们去外面看夜空。哇!每一分钟，天空中都有一道明亮的闪光。有时候，光有一条很长的尾巴。我觉得我在看一场烟火表演——只不过那是大自然制造的。我们看到了什么?流星。 我们有时把流星称为“流星”。但它们不是星星。它们是来自外太空的尘土和岩石。有些只有一粒沙子那么大。但当它们进入地球大气层时，就会形成壮观的流星雨。

Some scientists believe that the dinosaurs were killed by a massive meteor that hit the earth millions of years ago. But don't be afraid. Falling stars are natural. Go out and find one in the sky one dark night. It's worth the effort!

一些科学家认为，恐龙是由于数百万年前撞击地球的一颗巨大的流星而灭绝的。 但是不要害怕。流星是自然形成的。在一个漆黑的夜晚，走出去，在天空中寻找一个。付出是值得的!
