摘要
绿叶和鲜花都是从嫩芽开始的。发芽,长叶,开花,然后结果。树木的芽儿有棕色鳞片。这些鳞片保护嫩芽在寒冬和早春时不受伤害。它们被一种胶状物质紧紧黏住,因此形成了一个小笼子,防止嫩芽受到极端天气伤害。当天气变得够暖,膨胀的芽儿就把这些鳞片推掉;当树叶长出来,这些鳞片就会掉落,因为这时候它们已经没有用了。
Leaves as well as flowers come from buds.The bud swells,the leaves push out,the flower forms,and then comes the fruit.The buds of trees have brown scales over them.These scales shelter the tender bud from the cold of winter and early spring.
