Do you want to know how and why a fall leaf changes color? We first have to understand what leaves are and what they do.
        Leaves are the world’s food factories. Plants take water from the ground through their roots and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖), a kind of sugar. Plants use it as food for energy and growing.
        A chemical called “chlorophyll” in the leaves gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.
        During winter, there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories. As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves.
        The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples(枫树), sunlight and the cool nights of autumn turn the glucose in the leaves into a red colour. And we can enjoy the beautiful red leaves during autumn.

你想知道如何和为什么叶秋改变颜色?我们首先要了解什么是树叶以及他们做什么。叶子是世界各地的食品工厂。植物水从地面通过根部并采取 CO2 从空气。植物利用阳光将水和 CO2 转化为 glucose(葡萄糖)，一种糖。植物用它作为能源和种植的食物。一种叫"叶绿素"叶中化学给植物变成绿色。作为夏天结束，秋天来了，白天变得越来越短，和树木"知道"开始为冬天做准备。在冬天，那里是不足够的阳光和水分。树木在这段时间休息，生活上他们存储在暑假期间的食物。他们开始关闭他们的食物制作工厂。绿色的叶绿素从树叶消失后，我们开始看到黄色和橙色的叶子。鲜艳的红色和紫色我们看到在叶子都是大多是在秋天。在一些树，像 maples(枫树)、 阳光和秋天的凉爽的夜晚转成红色叶片中的葡萄糖。我们可以享受美丽的红叶在秋天。1

你想知道如何和为什么一个秋天的树叶改变颜色吗？我们首先要了解树叶是什么，他们做什么。        叶子是世界食品厂。植物从地上把水从根部吸收，然后从空气中吸收二氧化碳。植物利用阳光将水和二氧化碳转化为葡萄糖（一种糖，葡萄糖）。植物作为食物的能量和生长。        化学被称为“叶绿素”的叶子给植物变成绿色。随着夏天的结束和秋天的到来，白天变得越来越短，树“知道”开始准备过冬。        在冬天，没有足够的阳光和水。在此期间，树上休息，并住在他们的食物店在夏天。他们开始关闭他们的食品工厂。当绿色的叶绿素从树叶中消失，我们开始看到黄色和橙色的叶子。        明亮的红色和紫色我们看到叶子主要是秋天了。在一些树木，如枫树（枫树），秋天的阳光和凉爽的夜晚把葡萄糖在树叶变成红色。我们可以在秋天欣赏美丽的红色树叶。一
