Chapter 1 Salt Water About 70% of Earth is covered with water. Most of the water is in the oceans. There are five oceans the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean, and the Arctic Ocean. The largest ocean is the Pacific Ocean. It's 156 million square kilometers.

地球上大约3%的水是淡水。 大部分淡水都被冻结了。 这是冰。它存在于冰川或极地冰盖中。 一些淡水在湖泊和河流中。 北美的苏必利尔湖是地球上最大的湖泊之一。 面积约82000平方公里。 地球上最长的河流是非洲的尼罗河。 它大约有6700公里长。 一些淡水在天空中。 它在云和雨中。 有些水在土壤里，在岩石里，或者在地下的洞穴里。 发现!地球的大部分被水覆盖，但只有大约1%是我们可以饮用的淡水。 剩下的是盐水或冰。

Chapter 3 The Water Cycle Do you know where water comes from? When it rains, water falls from the sky. This is called precipitation. Rainwater goes into streams. Stream water goes into rivers. River water goes into seas and oceans. When it's sunny, the ocean water gets warm. Some water goes up into the sky. This is called evaporation. The water in the sky makes clouds. Then it rains again. This is called the water cycle. Discover! We're lucky to have water in our homes! About one billion people don't have clean water in their homes. Most of the water we use comes from rivers and reservoirs. Clean water goes through pipes to our homes.

你知道水是从哪里来的吗? 下雨时，雨水从天上落下。 这叫做沉淀。 雨水汇入溪流。 溪水流入河流。 河水流入海洋。 晴天时，海水变暖。 一些水上升到天空。 这叫做蒸发。 天空中的水形成了云。 然后又下雨了。这被称为水循环。 发现!我们很幸运家里有水!大约有10亿人家里没有干净的水。 我们使用的大部分水来自河流和水库。 干净的水通过管道输送到我们的家里。
