2026年通成学典课时作业本八年级英语上册译林版南通专版第96页解析答案——零五网—

① Is the sky bluer in autumn than in summer? The answer is yes! There are real reasons for this.
② The 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 our horizon. Instead, it is closer to the earth and more blue light is scattered(散射). This makes the sky seem bluer.
③ In 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.
④ You 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.
⑤ So, 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!

3. B 推理判断题。根据“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.”可知，空气中没有多少水分，所以云不容易形成，当天空中很少有或没有云覆盖时，天空的蓝色更明显，天空看起来更开阔，更明亮。由此可知，空气中的水分越少，天空的蓝色越明显，即空气中的水分越多，天空的蓝色越不明显。
