From red apples and yellow lemons to blueberries and green melons, fruit comes in many different colours. Why do different kinds of fruit have so many colours?
According to Chinese Academy of Sciences, fruit colours come from their different pigments (色素), such as red or yellow carotenoid (类胡萝卜素) and blue or purple anthocyanin (花青素). These pigments appear in different amounts (数量), depending on the fruit's environment. This causes the fruit to turn into a certain colour.
To find out how the environment influences fruit colours, Chinese scientists studied more than 280 different fruit colours, including white, red, blue, purple and black.
They found that red fruit tends to (倾向于) grow in cooler places. And instead of just growing in one place, you can find them growing in many places around the world. Blue and purple fruit mostly grows in warm places. The fruit tends to grow a lot in just one special area. The scientists also found that the closer the fruit is to the equator (赤道), the darker its colour will be.
Animals have also influenced the evolution (进化) of fruit colours. Animals eat fruit and drop the seeds (种子) in other places later. This helps the fruit spread and grow in different places. Therefore, in order to attract (吸引) animals, some fruit develops colours that are easy for animals to see.
▲ So fruit needs to develop colours that are suited to animals' visual (视觉的) abilities. For example, birds can see red more easily than humans can. Therefore, there tends to be more red fruit in areas where birds live. The lemurs (狐猴) of Madagascar are red-green colour-blind. Lots of yellow fruit can be found in their habitats (栖息地), as they can easily see this colour.

从红苹果、黄柠檬到蓝莓和绿瓜，水果有许多不同的颜色。为什么不同种类的水果会有这么多颜色呢？
据中国科学院介绍，水果的颜色来自于它们不同的色素，比如红色或黄色的类胡萝卜素以及蓝色或紫色的花青素。这些色素的含量因水果所处的环境而异，这就使得水果呈现出特定的颜色。
为了弄清楚环境是如何影响水果颜色的，中国科学家研究了280多种不同的水果颜色，包括白色、红色、蓝色、紫色和黑色。
他们发现，红色的水果往往生长在较凉爽的地方，而且它们不只是生长在一个地方，你能在世界上的很多地方发现它们的踪迹。蓝色和紫色的水果大多生长在温暖的地方，这类水果往往大量生长在一个特定的区域。科学家们还发现，水果离赤道越近，颜色就会越深。
动物也影响了水果颜色的进化。动物食用水果后，会在其他地方排出种子，这有助于水果在不同的地方传播和生长。因此，为了吸引动物，一些水果会呈现出动物容易看到的颜色。
然而，动物看颜色的方式是不同的。所以水果需要呈现出适合动物视觉能力的颜色。例如，鸟类比人类更容易看到红色，因此在鸟类生活的地区，红色的水果往往更多。马达加斯加的狐猴是红绿色盲，在它们的栖息地能发现很多黄色的水果，因为它们能很容易地看到这种颜色。
1. 一些水果呈现出特定的颜色是为了______。
A. 赶走动物
B. 获得更多阳光
C. 吸引动物来吃它们
D. 保护自己
2. 从文章中我们能了解到什么？
A. 颜色深的水果往往生长在炎热的地方。
B. 绿色的水果往往生长在凉爽的地方。
C. 人类比鸟类更容易看到红色。
D. 狐猴是色盲，辨别不出任何颜色。
3. 以下哪些因素影响了水果颜色的进化？
a. 环境
b. 色素
c. 动物
d. 科学家
A. ad
B. bc
C. ac
D. bd
4. 以下哪个句子适合放在“▲”处？
A. 水果和动物互相帮助。
B. 这就是为什么野生水果颜色更丰富。
C. 然而，并不是所有的动物都对颜色感兴趣。
D. 然而，动物看颜色的方式是不同的。
