月食的形成英文作文
英文：
A lunar eclipse, also known as a moon eclipse, occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon's surface. This phenomenon can only occur during a full moon, when the Sun, Earth, and Moon are aligned in a straight line.
During a lunar eclipse, the Moon gradually becomes darker and reddish in color. This is because the Earth's atmosphere refracts sunlight and bends it towards the Moon, casting a reddish hue on its surface. This is why a lunar eclipse is sometimes referred to as a "blood moon."
The duration of a lunar eclipse can vary, with some lasting only a few minutes and others lasting several hours. The next lunar eclipse is set to occur on May 26, 2021, and will be visible in parts of Asia, Australia, and the
western United States.

月食，又称为月蚀，是指地球在太阳和月球之间，将影子投射到月球表面的现象。

这种现象只能在满月时发生，当太阳、地球和月球处于一条直线上时。

在月食期间，月球逐渐变暗，并呈现出红色。

这是因为地球的大气层会折射阳光并将其向月球弯曲，使其表面呈现出红色色调。

这就是为什么月食有时被称为“血月”。

月食的持续时间可以不同，有些只持续几分钟，而有些则持续数小时。

下一次月食将于2021年5月26日发生，可在亚洲、澳大利亚和美国西部的部分地区观测到。
