Read the passage and put the following paragraph in the correct order.
( )The sea seems to have the best answer. There is plenty of water in the sea, but we need to take the salt away from the sea water. This is very expensive. If scientists can find cheaper ways to do it, we can solve the problem of the shortage of water. 阅读短文，按照正确的顺序把下面的段落写下来。
大海似乎有最好的答案。海里有大量的水，但我们需要把盐从海水中带走。这个很贵。如果科学家们能找到更便宜的方法
它，我们可以解决水资源短缺的问题。
( )How can we avoid a serious water shortage? First, they should save water and not waste it. Second, we should protect our water resource and not pollute them.Third, we should discover ways to reuse water. Scientists have made some progress in this field. Today, Some large cities are using their water. But people's need for water is increasing day by day. We still didn't have enough water, what else can we do?
我们怎样才能避免严重的水资源短缺？首先，他们应该节约用水而不是浪费。第二，我们应该保护我们的水资源而不是污染它们。第三，我们应该找到再利用水的方法。科学家在这一领域取得了一些进展。今天，一些大城市正在使用他们的水。但人们对水的需求日益增加。我们仍然没有足够的水，我们还能做什么？
( )Although the world is hungry, it's even thirstier. While nearly 3/4 of the earth is covered with water, we are still short of drinking water. This is because about 97% of the water on earth is sea water, so we can't use it for watering plants or drinking directly. Humans can only drink and use fresh water from places including rivers, lakes and underground.
虽然世界很饥饿，但它更饥渴。虽然地球近3/4被水复盖，我们仍然缺乏饮用水。这是因为地球上大约97的水是海水，所以我们不能用它来给植物浇水或直接饮用。人类只能饮用和使用来自河流、湖泊和地下的淡水。
