太空中的阴影焦点问题当地球和月球相互产生阴影时会发生什么?

What Is an Eclipse? The Sun is missing! Where did it go? People once told stories about why the Sun or Moon sometimes disappeared from the sky. Maybe a dragon ate it! Now we know it is an eclipse (e-KLIPS). An eclipse happens when Earth or the Moon blocks light coming from the Sun and makes a big shadow.

什么是日食?太阳不见了!它去哪儿了? 人们曾经讲过太阳或月亮有时会从天空中消失的故事。 也许被龙吃掉了!现在我们知道这是一次日食(e-KLIPS)。 当地球或月球挡住来自太阳的光线并产生巨大的阴影时，就会发生日食。

Imagine reading a book. Someone walks between you and the light. The person makes a shadow on the book, so it is hard to see the words. The Sun is a very bright light. But when Earth blocks light from the Sun, the Moon is hard to see.

想象一下读一本书。有人走在你和光之间。 这个人在书上投下阴影，所以很难看到书上的字。 太阳是一种非常明亮的光。 但是当地球挡住太阳的光线时，就很难看到月球了。

Hiding the Moon A full Moon is bright in the night sky. A shadow creeps across its face. An eclipse of the Moon is called a lunar eclipse. It happens when the Moon, Earth, and Sun line up. The Moon moves into Earth's shadow, so it looks dark. We see the Moon again when it moves out of this shadow.

藏起月亮满月在夜空中是明亮的。 一个影子在它的脸上爬过。 月食被称为月食。 它发生在月球、地球和太阳排成一线的时候。 月球移动到地球的阴影中，所以看起来很暗。 当月亮移出阴影时，我们又能看到它。

Sometimes the Moon, Earth, and Sun are in a straight line. The whole Moon is in Earth's shadow. This is a total lunar eclipse. Sometimes Earth's shadow does not cover the whole Moon. This is a partial (PAR-shul) lunar eclipse. Stages of a Lunar Eclipse 1. The Moon starts to enter Earth's shadow. 2. The Moon is covered by Earth's shadow. Light from Earth makes a dim glow on the Moon. This is a total lunar eclipse. 3. The Moon has almost left Earth's shadow.

有时月亮、地球和太阳在一条直线上。 整个月球都在地球的阴影下。 这是月全食。 有时地球的阴影并不能覆盖整个月球。 这是月偏食(PAR-shul)。 月食的不同阶段 月亮开始进入地球的阴影。 2. 月球被地球的阴影所覆盖。 来自地球的光在月球上发出微弱的光。 这是月全食。 3.月球几乎已经离开了地球的阴影。

Hiding the Sun The Sun disappears. Earth gets dark. But it is daytime! This is a solar eclipse. This time, the Moon gets between the Sun and Earth. The Moon blocks most of the sunlight and makes a shadow on Earth. Imagine holding your book in front of the light. It blocks the light and makes a shadow on you. This is like a solar eclipse!

藏起太阳太阳消失了。 地球变黑了。可现在是白天啊!这是日食。 这一次，月球位于太阳和地球之间。 月球挡住了大部分阳光，在地球上形成阴影。 想象一下把你的书放在灯光前。 它挡住了光线，在你身上留下阴影。 这就像日食一样!
