Tapescript
Good evening and welcome to this week’s episode of The Natural World. I’m Rebecca, and tonight we’ll be talking about water. About 70% of the Earth’s surface is covered by water, but 97% of it is salt water, which is not drinkable. Only about 3% of the water on Earth is fresh water, and most of that is locked up in ice. So, only about half a percent of Earth’s water is usable for drinking. Clean and safe drinking water is hard to find in many places.

Water is essential because most of the human body is made of water — around 60% in an average adult. Some parts of the body contain even more, like the brain, which is about 75% water. While humans can survive for weeks without food, we can only live a few days without water. We need around 2 to 3 litres of water per day, and athletes usually need more. In hot weather, people also require more water.
essential 重要的 = important
require sth. 寻求某物
require sb. to do sth. 要求某人做某事
while 然而（连词，表示对比）
I like tea, while my friend prefers coffee.
我喜欢茶，然而我的朋友喜欢咖啡。

However, much of the water we use goes into activities like washing clothes and taking baths. To save water, consider taking a quick shower instead of a bath, and remember to turn off the tap while brushing your teeth. This simple action can save over 100 litres of water in a week.
