五、阅读短文,完成任务。
About 70% of the Earth is covered with water. There is water above the ground, such as lakes and rivers. There is also water under the ground. There is even water in the sky! That is called
water vapour. There is water everywhere.
We have a lot of water, but we can’t drink most of it. About 97.5% of the Earth’s water is salt water. We can’t drink it. The rest is fresh water. As you know, we can drink fresh water. However, we can’t use most of our fresh water because about 70% is frozen (结冰的). Besides, about 30% of fresh water is groundwater (地下水). In fact, only a small part of the world’s fresh water is easy for us to use.
The Earth has always had the same amount (数量) of water. However, there are more people on Earth now, and we all need water. If we want to have water in the future, we must not waste it or pollute (污染) it now.
