《植物的奇妙世界》作者:罗恩·弗里德尔

Introduction Imagine a family is going out for dinner. The kids put on clean clothes. At the restaurant, Mom parks the car under a large tree. Inside, everyone sits at a wooden table. Dinner includes potatoes and fresh vegetables. They have fruit pie for dessert. They take the leftovers home in a cardboard box. Think about the clothes, tree, table, food, and box. What do they have in common? They all come from plants! You see plants almost everywhere. You also use plants in so many ways.

设想一家人外出吃饭。 孩子们穿上了干净的衣服。 在餐厅，妈妈把车停在一棵大树下。 在里面，每个人都坐在一张木桌旁。 晚餐包括土豆和新鲜蔬菜。 他们的甜点是水果派。 他们把剩菜装在纸板箱里带回家。 想想衣服、树、桌子、食物和盒子。 他们有什么共同之处? 它们都来自植物!你几乎到处都能看到植物。 你还在很多方面利用植物。

In this book, you will learn what plants need in order to live. You'll learn how they make their own food and how they make more plants. You'll also learn how animals and plants depend on each other. Plants are important living things. You would not survive without plants!

在这本书中，你将了解植物生存所需要的东西。 你将了解它们如何自己制作食物，以及如何制作更多的植物。 你还将了解动物和植物是如何相互依存的。 植物是重要的生物。 没有植物你就无法生存!

The Parts of a Plant Most plants have the same basic parts. Each part helps the plant get the water, air, minerals, and light that it needs to survive. The roots of a plant have important jobs. Roots usually grow down into the soil. In most plants, roots anchor, or hold, the plant in place. They help keep the plant upright, too. Roots absorb water and minerals from the soil. Minerals are the nutrients that help plants grow and be healthy. The roots also store some of the food made by the plant.

植物的组成部分大多数植物都有相同的基本组成部分。 每个部分都帮助植物获得生存所需的水、空气、矿物质和光。 植物的根有重要的作用。 根通常深入土壤。 在大多数植物中，根是固定植物的。 它们也有助于保持植物直立。 根从土壤中吸收水分和矿物质。 矿物质是帮助植物生长和健康的营养物质。 根也储存一些植物产生的食物。

The stem of a plant supports the leaves. It usually grows toward the Sun so the plant can get sunlight. The stem also moves water and minerals from the roots to other parts of the plant. And like roots, stems can store food and water for the plant. Do You Know? The stems of some plants are long. The trunk and branches of a tree are stems. Some plants have stems that creep along the ground, such as the vines of a strawberry or pumpkin plant. The stems of some plants, such as white potatoes, are underground.

植物的茎支撑着叶子。 它通常朝着太阳生长，这样植物就能得到阳光。 茎也将水和矿物质从根部转移到植物的其他部位。 和根一样，茎可以为植物储存食物和水。 你知道吗?有些植物的茎很长。 树干和树枝都是树干。 有些植物的茎沿着地面爬行，比如草莓或南瓜的藤蔓。 有些植物的茎，如白土豆，长在地下。

Leaves are another important part of most plants. Leaves are where plants make most of their own food. Leaves also get rid of the waste products that are made when the plant makes food. Leaves grow above the ground where the light is. They are usually flat, which helps them catch sunlight. Try This Study a leaf and talk about it. Are the edges smooth, wavy, or toothed like a saw? Is the tip pointy, rounded, or dented? Is the surface smooth, rough, bumpy, hairy, sticky, or waxy? Does light pass through the leaf?

叶子是大多数植物的另一个重要组成部分。 叶子是植物制造自己大部分食物的地方。 树叶还能清除植物制造食物时产生的废物。 有光的地方，叶子就长在地上。 它们通常是平的，这有助于它们捕捉阳光。 试一试这篇研究，并谈论它。 边缘是光滑的，波浪状的，还是锯齿状的? 尖端是尖的、圆的还是凹的? 表面是光滑的，粗糙的，凹凸不平的，多毛的，粘稠的，还是蜡状的? 光能穿过树叶吗?
