Where does the Earth usually get its light from? The sun, of course. The moon circles around the Earth, and sometimes it can come between the Earth and the sun, like it did in this picture.
Just like trees can block the sun to make shadows, so can the moon. The moon is much larger than a tree, so when it comes between the sun and the Earth, it makes a much bigger shadow. When it does, there is an eclipse.
This picture shows what an eclipse looks like from space. From the ground, it looks like the sun is covered by something round and black. The moon usually looks white because it is reflecting sunlight. During an eclipse, the side of the moon that we see from Earth is not reflecting sunlight, so it looks black.

地球的光線通常來自何方？當然是太陽囉！月球繞著地球轉，所以有時會擋在地球和太陽中間，正如照片所示。
月球會像樹一樣擋住陽光，製造陰影，而月球比樹大得多，所以當它擋在太陽和地球中間，就會製造出更大的陰影，這個情況便稱做日蝕。
這張照片是從太空看日蝕，若從地表看，會像是太陽被一個圓黑色的物體遮住。月球因反射日光而有亮白光澤。發生日蝕時，從地球望去的那一面月球因無法反射日光而顯出黑影。 （翻譯：鄭湘儀）
