  Water goes around and around Earth in a never ending journey called the water cycle(循環). The sun heats up lakes, oceans, and other wet places on Earth. When the water gets warm enough, it changes into vapour. Plants also give off lots of water vapour. Some of this water vapour cools off high in the sky and becomes clouds. Then it falls back to Earth in a new place as rain or snow. This cycle happens over and over again.

 The ground can absorb water like a sponge (海綿). If you could see this groundwater, it wouldn’t look like a lake or river. The groundwater is mixed in with the rocks and sand that lie in layers(層) below Earth’s surface.

 Groundwater moves along slowly. How slowly? Maybe 1.5 kilometres in one century. Some of this water has been underground for thousands of years. And once groundwater is pumped out of the ground from a deep well(井) by people, it may take hundreds of years for another water to take its place.

In which order does water go around Earth?

   a .Fall down as rain or snow.  b. Heated up by the sun on lakes, oceans and other wet places.

   c. Cool off high in the sky.     d.  Form clouds.     e.  Change into vapour.

   A. dacbe                B. becda           C. caebd          D. bceda

The groundwater seems to________.

   A. be just on the ground        B. be pure water like that in a lake or river

   C. exist in rocks and sand       D. flow along like rivers or streams

The underlined word “pumped” in the passage can be replaced by________.

   A. run                       B. pushed            C. drawn             D. picked

What conclusion(結論) can we draw from the passage?

   A. Groundwater can be quickly replaced by other water once pumped out.

   B. Groundwater is very valuable.

   C. Groundwater has nothing to do with human beings.        

   D. Groundwater travel in an unknown way.

Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads?

    Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.

    The heat-collector is a system of connected water pipes. Most of them ran from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.

    When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水層) into which several heat exchangers (交換器) have been built. The hot water from the street runs through these exchangers, warning the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.

    In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.

Which of the following is true according to the first two paragraphs?  

        A. Arian de Bondt got his idea from his boss.

        B. Large, flat, black surfaces need to be built in cities.

C. The Dutch engineer’s system has been widely used.

D. Heat can also be collected from asphalt roads.

For what purpose are the diving pipes used?  

        A. To absorb heat from the sun.             B. To store heat for future use.

C. To turn solar energy into heat energy.      D. To carry heat down below the surface.

From the last paragraph we can learn that __ 

        A. some pipes have to be re-arranged in winter

        B. the system can do more than warming up the building

        C. the exchangers will pick up heat from the street surface

        D. less heat may be collected in winter than in summer

What is most likely to be discussed in the paragraph that follows?  

         A. What we shall do if the system goes wrong.

         B. What we shall do if there are no asphalt roads.

         C. How the system cools the building in summer.

        D. How the system collects heat in spring and autumn
