A 跨学科 物理
[2025 南通市启东市期中]We all know the skies are blue on sunny days. But do you notice the colour of the mountains? 1.
D
In fact, all mountains look blue from a faraway place. It's really a magical thing. Do you know what's the reason for the blue skies and blue mountains?
2.
C

Sunshine is a mix of red, orange, yellow, green, blue, indigo and purple. The light in different colours has a different wavelength.
The atmosphere(大气层) is full of very small air molecules. When light meets them, it gets scattered around. 3.
E
The blue light is about half the wavelength of the red light and it gets scattered much more easily than the red light.

4.
A

More distance(距离) from a mountain means more atmosphere. Finally, we only see the blue light. The mountain disappears into the sky. The same thing happens with tall buildings, too.
5.
F

A. So blue is the main colour of the atmosphere.
B. This interesting science is very useful in our life.
C. You can find the answer from the science of sunshine.
D. You may say mountains are certainly green because of trees.
E. That means when meeting air molecules, light goes to different directions(方向).
F. You needn't feel surprised when you see blue mountains or buildings far away next time.
答案:1. D 根据“But do you notice the colour of the mountains?”可知,作者提到山的颜色,选项D“你可能会说山当然是绿色的,因为有树。”符合语境。
2. C 根据“Do you know what's the reason for the blue skies and blue mountains?”可知,作者询问蓝色天空和蓝色山脉的原因,选项C“你可以从阳光的科学中找到答案。”符合语境。
3. E 根据“When light meets them, it gets scattered around.”可知,光遇到空气分子时会被散射,选项E“那意味着当光遇到空气分子时,光会向不同的方向传播。”符合语境。
4. A 根据“The blue light is about half the wavelength of the red light and it gets scattered much more easily than the red light.”可知,蓝光的波长较短,更容易被散射,选项A“所以蓝色是大气的主要颜色。”符合语境。
5. F 根据“The same thing happens with tall buildings, too.”可知,同样的情况也发生在高楼建筑上,选项F“下次当你看到远处的蓝色山脉或建筑时,你不必感到惊讶。”符合语境。
解析:
【分析】
本题为英语七选五题型,解题思路如下:1. 通读全文,明确文章主旨是解释蓝天及远处山脉呈蓝色的原因;2. 逐个分析空格前后文的语境,抓住关键词、逻辑关系(如转折、设问、指代、因果等);3. 匹配选项,选择符合上下文逻辑、衔接自然的句子;4. 代入验证,确保所选选项使文章通顺连贯。
【解析】
1. 空格前提到山的颜色,空格后转折说明远处的山都是蓝色,D选项“你可能会说山当然是绿色的,因为有树”承接对山颜色的常规认知,与后文形成转折,符合语境;
2. 空格前提出“蓝天和蓝色山脉的原因”的问题,后文开始讲解阳光的组成,C选项“你可以从阳光的科学中找到答案”承接问题,引出下文的科学解释,符合逻辑;
3. 空格前说明光遇到空气分子会被散射,E选项“那意味着当光遇到空气分子时,光会向不同的方向传播”是对“散射”概念的具体解释,衔接紧密;
4. 空格前指出蓝光比红光更容易被散射,A选项“所以蓝色是大气的主要颜色”是前文散射特性得出的结论,因果关系成立;
5. 空格前说明同样的现象也发生在高楼建筑上,F选项“下次当你看到远处的蓝色山脉或建筑时,你不必感到惊讶”总结前文的现象,符合语境。
