When computer servers (服务器) operate a large program, they can get very hot. Cooling the servers can cost a lot. So some scientists want to know what would happen if the heat created by the servers could be used.

Data (数据) centres of large Internet companies such as Google and Microsoft have

thousands of computer servers. As these servers deal with information, they produce lots of heat, so they need huge cooling systems. These systems send the heat into the air.

A company in Holland (荷兰) thinks paying for electricity to operate (使运行) the servers

and then paying again to cool them are a waste of energy. So it developed a device (装置) called the e-Radiator. It contains a computer server connected to the Internet. By placing these servers inside people’s homes instead of out-the-way data centres, the company hopes to heat homes from excess computer heat, while lowering costs for the computer users.

Five homeowners in Holland are testing the heating system in their homes. Jan Visser is one of them. He says the amount of heat produced by the e-Radiator depends on the work being done by the computer server. “It’s a great help for my family,” he says.

The company says e-Radiators produce heat temperatures of up to 55℃. It says the system

could save its users about $440 in heating costs a year.

62.On the other hand,about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly.Man can only drink or use the other 3% of fresh water which comes from rivers,lakes and underground .And we can’t even use all of that,because some of them has been polluted.

Now more water is needed.The problem is:can we avoid a serious water shortage later on?Firstly,we should all learn how to save water.Secondly,we should find out the ways to reuse it.Today,in most large cities water is used only once,but it can be used again .Even if every large city reuse its water,still there would not be enough.What could people turn to next?

The sea seems to have the best answer.The is very big.Look at the map of the world,there is more sea than land.It covers three quarters of the earth.All that needs to be done is to get the salt out of the sea water.Scientists are trying to find a cheaper way of doing it.So you see,64如果我们可以找出解决方法，我们就不会有干涸（dry up）的危险。
