壹蘋派生活美語　血月：月亮的華麗變身

　　If it is a clear night on September 8, anyone in Taiwan who looks up at the sky will be able to see an incredible event. On that night, a shadow will slowly move across the Moon and cause it to appear red. This is because a lunar eclipse will be taking place. Lunar eclipses are rather regular events that can occur all around the world. During a lunar eclipse, the Earth is positioned directly between the Sun and the Moon. When this happens, the Moon’s access to the Sun’s light is blocked and the Earth casts a shadow over its surface.

　　如果九月八日那天晚上天氣晴朗，任何人在臺灣抬頭仰望夜空將能看到一個不可思議的現象。那晚，一道陰影會慢慢橫越月亮表面，使月亮呈現紅色。這是因為月食正在發生。月食是相當常見的現象，在世界各地都有可能發生。在月食期間，地球正好位於太陽和月亮之間。當這種情況發生時，月亮無法接收到太陽的光線，且地球會在其表面上投射陰影。
