标题:蓝莓的颜色 体裁:说明文 难度:★★★★ 建议用时:7分钟 正确率: /5
Do you like delicious blueberries? If so, when you eat next time, take a look at them. Are they really blue?
Not really. Take off the skin(表皮). The inside is white. Rub(摩擦) the inside of a blueberry on a white piece of paper. It is reddish-purple. And if you rub the outside of a blueberry, it gets almost black. But the moment you pick one, it does look blue. Why?
① The first way is through “structural colour（结构色）”. ② The blueberry makes “structural colour” in its own way. ③When the blueberry is full grown, it is black. ④But a thin layer of wax(蜡层) on the outside of the blueberry gives it a blue look.
The second is through plant pigments（色素）. The pigments on the blueberry skin take in green and yellow light and reflect(反射) blue light. That's why blueberries look blue in our eyes. In fact, there isn't any “true blue” in the plants. We can also see the similar features（特点） on the green leaves.
The blueberry's special colour way is cool. It shows nature's magic. More secrets in our nature are waiting for us to discover! Now your bowl of blueberries suddenly looks a lot more interesting!

【语篇解读】本文是一篇说明文，主要介绍了蓝莓为什么是蓝色的。
1. B 细节理解题。根据“And if you rub the outside of a blueberry, it gets almost black.”可知，在摩擦蓝莓的表皮后，蓝莓看起来几乎是黑色的。故选 B。
2. A 补全文章题。句子“There are two ways to make colours.”介绍了制造颜色的两种方式，而第三段和第四段中的句子“The first way is through ‘structural colour’.”和“The second is through plant pigments.”则分别对这两种方式进行了详细解释。因此，该句应该放在介绍第一种方式的句子之前，即句子①之前。故选 A。
3. D 图示理解题。根据“The pigments on the blueberry skin take in green and yellow light and reflect blue light. That's why blueberries look blue in our eyes ... We can also see the similar features on the green leaves.”及常识和植物学知识可知，叶子呈现绿色的原因是叶子中的叶绿素吸收了红光和蓝光，而反射了绿光，所以我们看到的叶子是绿色的。故选 D。
4. A 写作意图题。文章主要说明了蓝莓呈现蓝色的原因，包括结构色和植物色素的作用。故选 A。
5. D 推理判断题。在文章最后一段中，作者提到“More secrets in our nature are waiting for us to discover!”，强调自然界中的更多秘密还等待着我们去发现。故选 D。
