二、Amy 给同学们讲述了夏秋更迭时天空颜色的秘密，同学们感叹四季的变化真是充满了学问。阅读下文，一起解锁这个秘密吧！
① Is the sky bluer in autumn than in summer? The answer is yes! There are some 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 us any more. 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 make 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!
(
A. By asking a question.
B. By telling a joke.
C. By using an old saying.
D. By making a survey.
(
A. Because the sun is shining directly on us.
B. Because the sun is closer to the earth.
C. Because the sun is smaller in the sky.
D. Because the sun is covered by the clouds.

Frost forming in autumn happens when cold air(below 0℃) meets wet air near the ground, turning water vapor in the wet air into ice crystals.(言之有理即可)
答案
1. A 【解析】根据文章开头的“Is the sky bluer in autumn than in summer?”可知，作者通过提问的方式引出本文话题。
2. B 【解析】根据第二段中“Instead, it is closer to the earth and more blue light is scattered. This makes the sky seem bluer.”可知，秋天的天空看起来更蓝是因为太阳离地球更近。
3. B
4. A 【解析】通读全文可知，第一段提出了问题并给出了直接答案；第二、三、四段分别解释了三个原因；第五段鼓励读者在秋天欣赏美丽的天空并记住这些原因，因此A项符合文章结构。
