地球。月球。太阳。以及Alyse Sweeney的《星星》

Introduction When we look up into the sky, we are looking into outer space. We can see the Sun, the Moon, and stars. They all seem to move very slowly across the sky. We live on a giant ball of rock and water called Earth. We don't see it because we live on it! It is also moving through space. It moves in a giant circle around the Sun.

当我们仰望天空时，我们是在仰望外太空。 我们可以看到太阳、月亮和星星。 它们似乎都在天空中移动得非常缓慢。 我们生活在一个巨大的岩石和水的球体上，叫做地球。 我们看不到它，因为我们生活在它上面!它也在空间中移动。 它围绕太阳做一个巨大的圆周运动。

The Moon is also a ball of rock, but it is smaller than Earth. The Moon moves in a giant circle around Earth. As Earth moves around the Sun, the Moon moves around Earth. Let's learn more about Earth, the Sun and stars, and the Moon. Let's learn about how they move through space.

月球也是一个岩石球，但它比地球小。 月球绕着地球做一个巨大的圆周运动。 地球绕着太阳转，月球也绕着地球转。 让我们来了解更多关于地球、太阳、恒星和月球的知识。 让我们来了解一下它们是如何在空间中移动的。

Earth Earth is where we live. It is one of eight planets that go around the Sun. Earth is the third planet from the Sun. Being this far away keeps Earth from getting too hot or too cold. Planets closer to the Sun are so hot that steel would melt. Planets farther away are way too cold. Earth has the right amount of heat and light for plants and animals to live here.

地球是我们生活的地方。 它是围绕太阳运行的八大行星之一。 地球是离太阳第三远的行星。 这么远的距离使地球不会变得太热或太冷。 离太阳更近的行星温度高到钢铁会融化。 更远的行星太冷了。 地球上有足够的热和光让植物和动物在这里生存。

Most of Earth is covered by water. Water is also below ground and in the air. That's why Earth is called the water planet. Living things need water to live. They also need air. Earth has a blanket of air around it. This blanket of air is called the atmosphere.

地球的大部分被水覆盖。 水也存在于地下和空气中。 这就是为什么地球被称为水行星。 生物需要水才能生存。 它们还需要空气。地球周围有一层空气。 这层空气被称为大气。

The Sun The Sun is just one of billions of stars in space. Like most stars, it is a giant ball of very, very hot gas. The Sun sends light to Earth. Light from the Sun hits Earth. It lets us see during the day. The light changes to heat when it hits Earth. The heat rises and warms Earth's atmosphere. Without the Sun, Earth would be dark, cold, and lifeless.

太阳只是宇宙中数十亿颗恒星中的一颗。 像大多数恒星一样，它是一个由非常非常热的气体组成的巨大球体。 太阳向地球发送光。 来自太阳的光照射到地球。 它能让我们在白天看到东西。 当光线到达地球时，会变成热量。 热量上升，使地球大气层变暖。 没有太阳，地球将是黑暗、寒冷和没有生命的。
