1·Why does chlorophyll need protection when it is the natural world's supreme light absorber?为什么叶绿素是自然界最高等的光吸收体，却需要保护？
-
2·It's colder there, they're more stressed, their chlorophyll is more sensitive and it needs more sunblock.那里更冷，它们受到更大压力，它们的叶绿素更敏感，并且需要更多的避光措施。
-
3·Why protect chlorophyll at a time when the tree is breaking it down to salvage as much of it as possible?在树木将叶绿素分解，以尽可能多地将其回收的时候，为什么我们还要保护叶绿素呢？
-
4·As chlorophyll is depleted, other colours that have been dominated by it throughout the summer begin to be revealed.当叶绿素耗尽时，在整个夏季被它主导的其他颜色开始显现。
-
5·Before letting its leaves go, the tree dismantles their chlorophyll molecules and ships their valuable nitrogen back into the twigs.在树叶凋落之前，树会分解叶绿素分子，把有用的氮运回树枝中。
-
6·The weakened fall leaf then becomes vulnerable to the highly destructive effects of the oxygen created by the excited chlorophyll molecules.活跃的叶绿素分子产生的氧气破坏性强，秋天衰弱的树叶随后变得更容易受到影响。
-
7·The slugs can manufacture chlorophyll, the green pigment in plants that captures energy from sunlight, and hold these genes within their body.蛞蝓可以制造叶绿素——让植物从太阳光获取能量的绿色色素——并把这些基因保留在他们体内。
-
8·Summer leaves are green because they are full of chlorophyll, the molecule that captures sunlight converts that energy into new building materials for the tree.夏天的树叶是绿色的，因为它们富含叶绿素，这种捕捉阳光的分子可以将这些能量转化为新的树木生长材料。
-
9·The energy absorbed by the chlorophyll molecules of the unstable autumn leaf is not immediately channelled into useful products and processes, as it would be in an intact summer leaf.不稳定的秋叶叶绿素分子吸收的能量，不会像在完好的夏叶中吸收的能量那样立即传输到有用的产品和工艺流程中去。
-
10·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。
