《我们从哪里获取能量》，作者：杰弗里·B·弗斯特

Introduction. We use energy for many of the things we do every day. Energy lights, heats, and cools our homes and schools. It allows things to move around. You need energy to run and play. You need energy to think and sleep. Where does this energy come from?

引言。 我们每天做很多事都要用到能量。 能量可以照明、供暖、 给我们的家和学校降温。 它能让物体移动。 你跑步玩耍都需要能量。 你思考和睡觉也需要能量。 这些能量是从哪里来的呢？

Energy comes from many kinds of important natural resources. Sunlight is our most important natural resource. Coal, natural gas, and oil are natural resources too. So are things like plants, wind, and water.

能量来自多种重要的自然资源。 阳光是我们最重要的自然资源。 煤炭、天然气和石油也都是自然资源。 植物、风、水之类的东西也属于自然资源。

Energy from food sources. You get energy from foods you eat. Animals you eat may get energy from the plants they eat. Plants use energy from the sun to make their own food. Plants can store the food they make in roots, stems, and leaves.

来自食物的能量。 你从吃的食物中获取能量。 你吃的肉类动物可能从它们吃的植物中获取能量。 植物利用太阳的能量来制造自己的食物。 植物可以把制造的食物储存在根、茎和叶子里。

Energy from gasoline. Most cars, trucks, planes, and trains get energy from gasoline. Gasoline is made from oil. Oil is a natural resource found deep underground. Wells pump oil up from the ground. Factories change the oil into gasoline.

来自汽油的能量。 大多数小汽车、卡车、飞机和火车都从汽油中获取能量。 汽油是用石油制成的。 石油是埋藏在地下深处的自然资源。 油井把石油从地下抽上来。 工厂把石油加工成汽油。

Electricity. Electricity is a kind of energy. We use electricity to run many things that we use every day. How do we get electricity?

电。 电是一种能量。 我们用电力来驱动很多日常使用的物品。 我们是怎么得到电的呢？
