It sounds paradoxical, because the idea behind this hypothesis is that the red pigment is made in autumn leaves to protect chlorophyll, the light-absorbing chemical, from too much light.
这听起来很矛盾，因为这一假设背后的理念是，树叶在秋天产生的红色素是用于保护叶绿素这种吸收光的化学物质，以免它吸收过多的光。
As a result, the green chlorophyll is slowly leached away, revealing the yellow and orange hues seen in some tree species come autumn. Red leaves are another story.
其结果是，绿色的叶绿素是慢慢地被过滤了出来，在某些树种中，从它们所展现的黄色和橙色的色调里可以看到秋天的到来。可是红叶却是另外一件事。
The trees are red, more to the deep autumn, it is red, far from looking like a flame in rolling.
千树万树的红叶，愈到秋深，愈是红艳，远远看去，就像火焰在滚动。
