跨学科 生物 Do you like blueberries? If so, the next time you're about to eat these delicious berries, take a good look at them.
For the most part, blueberries aren't blue. If you carefully take off the skin of one blueberry, you'll see that the fruit inside is white. If you rub the inside of the skin on a white piece of paper, you'll see a reddish-purple colour. And if you gently rub the outside of a blueberry, the blue colour disappears and the berry looks almost black. But the moment you pick one, it does look blue. What's going on?
Well, there are two ways to create colours. The first is through pigments(色素). Pigments show the colour of the light they don't take in. The most common pigment in plants is chlorophyll(叶绿素), a green pigment. Plant leaves appear green because chlorophyll doesn't take in green light. It sends it out instead while taking in blue and red light. Plants prefer to take in blue light because it has more energy than any other light. In fact, there aren't any "true blue" pigments in the plant world.
The second way to make colour is through "structural colour". This happens when the surface makes some colours of light look different. Have you ever seen the rainbow colours on a CD? These colours show up because of the tiny spaces between the CD's thin layers. These spaces only allow certain colours to reach our eyes.
Blueberries also create "structural colour" in their own way. The berries look black when they're ripe(成熟的), but the plants build a thin layer of wax(蜡) on their outside. This layer is only 0.4% of a centimeter thick, but it gives the berries their blue look. The blue colour helps the plants because birds are attracted to the rare colour. They eat the berries and spread the seeds far and wide.
1. According to the article, after you gently rub the outside of a blueberry, it almost looks
A. blue B. white C. black D. reddish-purple

答案
时文阅读
1--4 CBAA
【语篇解读】本文是一篇说明文，主要介绍蓝莓呈蓝色的原因。
1. C 解析:细节理解题。根据第二段“And if you gently rub the outside of a blueberry, the blue colour disappears and the berry looks almost black.”可知，轻轻擦拭蓝莓的外表后，它几乎看起来是黑色的。故选 C。
2. B 解析:图示理解题。根据第三段“Plant leaves appear green because chlorophyll doesn't take in green light. It sends it out instead while taking in blue and red light.”可知，植物叶子呈绿色是因为叶片中含有叶绿素，而叶绿素主要吸收红光和蓝光，不吸收绿光，故而绿光被反射回来，使得叶片呈绿色。故选 B。
3. A 解析:推理判断题。根据第四段“The second way to make colour is through ‘structural colour’ ... Have you ever seen the rainbow colours on a CD? These colours show up because of the tiny spaces between the CD's thin layers.”以及最后一段“Blueberries also create ‘structural colour’ in their own way.”可知，蓝莓呈现蓝色，就像 CD 呈现彩色一样，两者都是通过“结构色”制造颜色。故选 A。
4. A 解析:补全文章题。根据第一段“Do you like blueberries? If so, the next time you're about to eat these delicious berries, take a good look at them.”及下文“For the most part, blueberries aren't blue.”可知，此处承上启下，引出蓝色这一话题。故选 A。

解析
【分析】
1. 第1题是细节理解题，需定位原文关于擦拭蓝莓外表后的描述，直接匹配选项；
2. 第2题是图示理解题，需结合生物知识中叶绿素的吸光特性：叶绿素吸收红光和蓝光，反射绿光，因此叶片呈绿色，对应图示中光线的走向；
3. 第3题是推理判断题，需明确蓝莓呈蓝色的原理是“结构色”，找到文中提到的结构色例子（CD），匹配选项；
4. 第4题是句子补全题，需分析句子的承上启下作用，结合第一段和第二段的内容衔接，确定放置位置。
【解析】
1. 第1题：根据原文第二段“And if you gently rub the outside of a blueberry, the blue colour disappears and the berry looks almost black.”可知，轻轻擦拭蓝莓外表后，它几乎呈黑色，故选C；
2. 第2题：根据原文第三段“Plant leaves appear green because chlorophyll doesn't take in green light. It sends it out instead while taking in blue and red light.”，即叶绿素吸收红光和蓝光，反射绿光，对应图示中太阳发出的红、蓝光被叶片吸收，绿光被反射进入眼睛，故选B；
3. 第3题：根据原文第四段“The second way to make colour is through ‘structural colour’... Have you ever seen the rainbow colours on a CD?”及最后一段“Blueberries also create ‘structural colour’ in their own way.”，可知蓝莓和CD都是通过结构色呈现颜色，故选A；
4. 第4题：待补全句子“Then ask yourself: Are blueberries really blue?”承接第一段“take a good look at them”的动作，引出下文关于蓝莓颜色的讨论，应放在第一段末尾，故选A。
