The Milky Way written by Barry Holden

巴里·霍尔登的《银河系

Look at all the stars in the sky at night. They are a long way out in Space. The stars are so far away that they look very small. telescope We can't see them in the daytime, but we know that they are up there.

看看夜空中所有的星星。 他们在太空中还有很长的路要走。 星星离我们很远，看起来很小。 我们白天看不见它们，但我们知道它们就在天上。

We live on the planet called Earth. Our part of Space is called the Milky Way. Milky Way Most of the things we can see in the sky are in the Milky Way.

我们生活在一个叫做地球的星球上。 我们所在的那部分空间叫做银河系。 我们在天空中看到的大部分东西都在银河系中。

Earth looks like a blue and white ball when it is seen from Space. It is smaller than any of the stars. Earth is the only planet that has water, and we all need water to live. Earth Earth turns as it goes around the Sun. It takes a day for one turn, and a year to go right around the Sun.

从太空看地球就像一个蓝白色的球。 它比任何一颗恒星都小。 地球是唯一有水的星球，我们都需要水来生存。 地球绕着太阳转。 绕太阳一周需要一天，绕太阳一周需要一年。

Did you know that the Sun is a very big star? It is more than a hundred times bigger than Earth! The Sun is the closest star to Earth. sun As Earth turns to the Sun, our day gets light and warm. When Earth turns away, it gets dark, and we can get very cold.

你知道太阳是一颗很大的恒星吗? 它比地球大100多倍!太阳是离地球最近的恒星。 当地球转向太阳时，我们的一天变得光明和温暖。 地球一转，天就黑了，我们就会很冷。

Our Moon is much smaller than Earth. It goes slowly around us, and it takes a month to go right around. moon The Moon is round, but sometimes we can only see part of it.

月球比地球小得多。 它绕着我们转得很慢，绕一圈需要一个月的时间。 月亮是圆的，但有时我们只能看到它的一部分。
