英语翻译
If we observe carefully,we can find that most of the flowers in nature are red,orange and yellow.If we have seen a black foower,it's chance in a million.people have made a census to colors of more than four thousand kinds of flowers and discovered that only eight of them are black.Why?
As we know,sunlight is formed is formed by seven different kinds of colored light.The wave length of each light changes.So the quantity of heat in each light changes,too.Flowers,especially their petals,are very delicate and prone to the harm caused by high temperature.Black fomwers can take in all the light waves,which cause the flowers to dry up in a high temperature.So black lowers can rarely survive sunlight.But ted flowers.orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light,orange light and yellow light,each of which has a large quantity of heat.
That is why red,orange and yellow flowers are very common in nature while black flowers are so rare.

答案

如果我们仔细观察,就会发现自然界中绝大部分花的颜色是红,橙,黄色的,看到黑色花的机率大约百万分之一,人们做过统计,四千种花中只发现八种黑色花,这是为什么呢?
我们知道太阳的光谱是由七种不同颜色的光组成的,每一种光的波长总在变,因此每一种光所含的热量也在变,花,特别是花瓣非常娇嫩,很容易受高温伤害,黑色花能够吸收所有光波,这会使花在高温下干枯,因此黑色花在阳光下很难成活,
