關於樹葉的英語知識：樹葉脫落前變色的真正原因You've probably heard that leaves of deciduous trees change color in autumn because they lose their green chlorophyll molecules,allowing the underlying yellow-orange pigments to shine ver,this doesn't explain why the leaves change color in the first place.
你可能聽過這種說法：落葉樹在秋天變色是因爲它們失去了令它們綠的葉綠素，於是下層的黃橙色素就顯出了顏色。但是這解釋不了樹葉開始變色的位置。
Deciduous trees drop their leaves each year to avoid the high cost of winterizing them,but this seasonal shedding would be too wasteful to be worth doing if the tees lost all of the valuable nutrients they laboriously extracted from the soil to build their leaves earlier in the each fall,deciduous trees recycle their leaves before dropping then.
落葉樹每年落葉是爲了降低冬天防凍的消耗，但是如果樹木因此失去了它們這一年來爲了生枝長葉辛苦從泥土中汲取來的珍貴營養鹽，那麼季節性脫落就太過浪費 太不值了。
That means taking apart cells and photosynthetic apparatus from the inside out in order to recoup their nitrogen and phosphorus and store it in twigs and branches until next is actually really use as the disassembly starts,the chlorophyll molecules that absorb sunlight for photosynthesis are still absorbing the sun's energy.
因此 每次落葉前落葉樹會對樹葉進行營養回收。也就是說會對樹葉的細胞和光合器進行拆解回收氮和磷，並將它們儲在樹枝中等待來年春天。這過程非常巧妙 因爲隨着分解開始，葉綠素爲了光合作用 吸收太陽能的過程依然在繼續。
But with no photosynthesis happening,they end up passing the unused energy along to oxygen molecules,which become dangerously reactive when e molecules wreak havoc,damaging the parts of the leaf that are in the process of recovering and transporting nutrients back to the rest of the keep this destruction to a minimum,leaves break down their chlorophyll into less dangerous molecules that are typically transparent,though sometimes yellow.
但是因爲不再發生光合作用，它們將多餘的能量給了氧分子，此時氧分子一旦被激發會發生危險反應。這些氧分子橫行肆虐，破壞了樹葉中正在進行回收將剩餘營養鹽輸送回樹木的那部分組織。爲了將破壞將至最低，樹葉關閉葉綠素功能 使之變成低危險的分子，這些分子通常是透明的 也有些是黃色的。
Either way,with the bright green molecules gone,yellow and orange pigments that were there all along (helping with photosynthesis),are no longer overshadowed,and ta-ta!Yellow and orange trees take an extra autumnal precaution against chlorophyll-induced-destruction:as the leaf dismantling starts they build newspecial pigments to shade chlorophyll from sunlight until it can be broken down.
無論如何 隨着綠色分子的消失，黃色和橙色的色素卻一直都在(協助進行光合作用)葉子不再褪色 噹噹噹當!黃色和橙色的樹葉。有些樹採取了額外的秋季防禦措施 避免葉綠素造成的危害：隨着樹葉開始分解 它們會形成新的特殊色素 遮擋葉綠素 防止其吸收陽光 直至葉綠素被分解。
These new pigments tend to be red or purple in color,so trees that use them have red leaves in the fall-sometimes insanely bright the end,these exquisite gold and russet displays help deciduous trees recover as much as 50% of the nitrogen and phosphorus from their old leaves to help grow fresh new green ones in the are perhaps the world's prettiest recycling plants.
這類新色素通常是紅色或紫色的，因此使用它們的樹木 落葉是紅色的——有時會是鮮紅色。最後 這些漂亮的金色和黃褐色葉片 幫助樹木從舊葉中回收50%的氮和磷令大樹可以在新春煥發新綠。它們大概是世界上最漂亮的回收工。
