Why the Sky Looks Blue ?
When they look at the sky, people usually find the sky looks blue---not orange, red, green or yellow! Do you know why?
It gets its blue colour from the sunlight that shines through the air. Sunlight contains all the colours which the rainbow ( 虹 ) is made up of, but these colours are scattered ( 扩散 ) as they pass through the air. Some colours are scattered more than others, and the colour that is scattered the most is the colour you see---blue.
The sky usually looks light blue. But it would be deep, dark blue if you stood on top of the highest mountain, where there is less air between you and the sun to scatter the sunlight. And if you rode in a rocket high above the earth, where there is no air at all to scatter the sunlight, the sky would be so dark that it would be black.
Sometimes the sky doesn't look blue. At sunrise and sunset, the light from the sun sometimes is scattered in such a way that you see red, orange, and other colou

where there is no air at all to scatter the sunlight, the sky would be so dark that it would be black. 说明C是对的
At sunrise and sunset, the light from the sun sometimes is scattered in such a way that you see red, orange, and other colours in the sky.
说的是当日出或日落时,,你会看见红色,橙色,和其他颜色在空中.所以D是错的
A,B 就不解释了.
从最后一句话At sunrise and sunset, the light from the sun sometimes is scattered in such a way that you see red, orange, and other colours in the sky.
可以得出 在日落的时候 天空有可能是红色,橘黄色或者其他的颜色 所以D是对的
