Ⅱ. 科学探究 David 研究了夏秋更迭时天空颜色的秘密,让人感叹四季的变换真是充满了学问!
①Is the sky bluer in autumn than in summer? The answer is yes! There are some reasons for this.
②The sun is lower in the sky in autumn. As the days get shorter, the sun appears lower and lower in the sky. It doesn't shine directly on us anymore. Instead, it is closer to the earth and more blue light is scattered(散射). This makes the sky seem bluer.
③In autumn, there is less water in the air, so there are fewer clouds. Autumn is known for good weather—cooler temperatures and less wet air. The air does not hold much water, so clouds do not form easily. When there are few or no clouds covering the sky, the blue colour of the sky shows more clearly, and the sky looks more open and brighter.
④You might be surprised, but the colourful leaves of autumn actually help give the sky's blueness a colour boost(增强), which can make the sky seem even bluer. If you've made a colour wheel for an art class, you know that blue and orange are opposite colours that look good together. The red, orange, and gold leaves of autumn make the blue sky stand out beautifully against them. This contrast looks nice and creates a special autumn view.
⑤So, the next time you're out enjoying the beautiful weather in autumn, take a moment to look up at the sky, remember these reasons why it looks so blue and enjoy the view!
