3.BThe world is not only hungry,it is also thirsty for water. this may seem strange to you,since nearly 75% of the earth is covered with water. But about 97% of this water is sea water.Man can only drink and use the other 3% fresh water that comes from rivers,lakes,under-ground and other places. And we cannot even use all of that,because some of this fresh water has been made dirty.At the moment,this small amount(数量) of fresh water is still enough for us. However,our need for water is getting greater and greater. Only if we take steps to solve this problem now,we can get away from a serious world water shortage later on. The people of the world cannot have an enjoyable life without enough clean water.On one hand we should stop wasting this little water of ours,on the other hand we should find ways to reuse it,but this has not been done widely.Today,in most large cities,water is used only once and it then returns to the sea or runs into underground places.lf we can make it clean again,it can be used once more just as if it were fresh from a spring.But even if large cities reuse its water,we still would not have enough in the future. Where.could we turn to next for water? To the ocean! How can we do to make use of this great a-mount of sea water? We can take the salt from the water to make it fresh.So if we take all these steps,we'll be in no danger of drying up!( )26. Why does the writer say that the world is thirsty for water?A. The amount of fresh water is really very small.B. The people of the world waste too much water.C. The people of the world have to drink a lot of water every day.D. There are too many people in the world needing water.

    请阅读 Passage 1,完成第 21~25小题。Passage 1These days,many large city buildings are equipped with their own air-conditioning systems.These systems help keep the buildings cool,but they can also damage the environment.Since they use a lot of electricity,for instance,they contribute indirectly to global warming.In addition,the water that flows through the systems is often cooled using chemicals called chlorofluorocarbons,or CFCs,that are believed to damage the Earth's ozone layer.Recently,though,a system has been built in the city of Toronto,Canada,that cools buildings with little damage to the environment. In the traditional air-conditioning systems found in most large buildings,water is pumped through the building in a continuous cycle.The water is first cooled to a temperature of 4℃ in machines called chillers.It is then sent to individual units that cool the air in each room.As the water flows through the building,it gradually becomes warmer.Finally,it reaches the roof ,where it is left to cool down naturally in a water tower.After that it is returned to the chillers,where the cycle begins again.Toronto lies on the shore of Lake Ontario,one of North America's Great Lakes,and the new system makes use of cold water taken from about 80 meters below the surface of the lake.At this depth,the water in the lake remains at 4℃ all year round.This is exactly the temperature to which the water in air-conditioning systems is cooled.However,the water from the lake is not pumped directly into the air-conditioning systems.Instead,it is used to cool the water that is already inside the air-conditioning systems.After that,the lake water is added to the city's ordinary water supply.Enwave,the company that developed this deep-lake cooling system,says that it uses 75 percent less energy than traditional air conditioning.And since no CFCs are used,no damage can be caused to the ozone layer.Not every city is located next to a large lake,but experts believe that systems like the one being used in Toronto could be built elsewhere by using other natural sources of cold water.What happens in the end to the water from Lake Ontario?
    A

    It is used by the residents of Toronto.

    B

    It is returned to a place deep in the lake.

    It is cooled down before being used again.

  • 第15题:

    The water we drink and use is running short in the world.We all have to learn how to stop wasting our limited water.One of the steps we should take is to find ways of reusing it.Experiments have already been done in this field.
    Today in most large cities,fresh water is used only once,then it runs into waste system.But it is possible to pipe the used water to a purifying factory.There it can be filtered and treated with chemicals so that it can be used again,just as it were fresh from a spring.
    But even if every large city purified and reused its water,we still would not have enough.Then we could turn to the oceans.All we’d have to do to make use of the seawater on earth is to get rid of the salt.This process is called desalinization,and it is already in use in many parts of the world.
    The way to stop wasting our limited water is to________.

    A.do experiments with water
    B.purify the used water and reuse it
    C.use fresh water once again
    D.make use of seawater
