When we want water, its there- we cook with it, we wash with it, and when were thirsty we drink it. Water is very, very important our surv
10、ival on our planet. Here are some facts that perhaps you didnt know about water.Speaker2: One- there are two kinds of water on planet Earth: fresh water and salt water. We can only drink fresh water. Salt water isnt drinkable.Speaker1: Two- of all the fresh water on the planet, people can only get t
11、o and use about one per cent of it. Only one per cent- the other 99 per cent of fresh water is in places we cant get to. For example.Speaker2: Three- about 70 per cent of all the fresh water on the earth is in Antarctica, at the South Pole, in the ice and icebergs there. Lots of fresh water, but its
12、 frozen, and very far away from where we live. So we cant use it.Speaker1: Four- most of us get our water at home out of a tap. Sometimes the tap drips because its old or because someone hasnt turned it off properly. So what? Well, a dripping tap can sometimes waste about 75 litres of water every da
13、y.Speaker 2: Five- in western homes- in the USA for example, or in Europe- one person can use as much as 500 litres of water a day. An African family might only use about 20 litres a day.Speaker1: Six- every day, millions of people - especially women and children- walk very long distances to get wat
14、er, from rivers or lakes or wells, and sometimes the water is dirty and polluted. This means lots of bad things, for example.Speaker 2:Seven- many people get sick because they drink dirty water. 88 per cent of all diseases in the world are caused by drinking dirty water.survival svaivl n.1.幸存;残存U 2.

16、 organisation. We help people in developing countries to get safe drinking water and sanitation. It is our aim to make sure the one day, everyone in the world can get safe water to drink.Radio host: Why is that there are such problems with safe water? If its true that people can only get to and use
17、one per cent of all the fresh water on the planet. Then Im sure a lot of listeners will ask “Where is the rest?“Expert: Thats a very good question. First of all, when we talk about fresh water we have to remember that 97.5 per cent of the worlds water is slat water, and only 2.5 per cent is fresh wa
18、ter. Now, of all the fresh water that there is in the world, 70 per cent is frozen in the polar ice caps.Radio host: Well, but what about the rest? That still leaves us 30 per cent of all the fresh water, doesnt it?Expert: Not really. Most of the 30 per cent is in the ground- we wouldnt have grass o
19、r plants or trees if the soil wasnt moist. Then there are also huge underground lakes, deep down in the ground , but we dont have access to them, because it would be too expensive to get to them, so we can only get to one per cent of the fresh water supply, and thats in lakes, rivers, reservoirs, an
20、d in underground sources that are not too deep in the ground, so we have access without huge costs.Radio host: What about the rainfall? Can you tell us something about that?Expert: Yes. Of all the water falling onto our planet, about two-thirds goes back up into the atmosphere through a process call
21、ed evaporation, or else plants take it up. About one-third of the rainfall ends up in the worlds rivers. The problem of course is that the worlds population is growing very fast, and as a consequence there is about 40 per cent less fresh water available per person than there was, say, 50 years ago.Radio host: I see. Can you give us a rough idea of.evaporation i,vprein n. U 蒸发; 发散consequence 英音：k nsikwns n.结果, 后果C
