Question

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 run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the groun.

When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes itunderground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer(蓄水層) into which heat several heat exchangers (交換器) have been built. The hot water from the street runs through these exchangers, warming 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.

1.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.

2. 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.

3.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

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

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

B. What shall we 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.

4.C

【解析】

試題分析：最簡單方法往往很有效。城市里既然有了巨大的“深色”表面，為什么不用來收集太陽能呢？荷蘭工程師 Arian de Bondt 就發(fā)明了這樣一個系統(tǒng)，用于在城市道路上收集太陽熱量，以便儲存加熱地底的水，還可以在冬季使用。

1.

in the form of asphalt (柏油) roads?”可知柏油路也可以用來收集熱量。故選D。

2.

ground-water, before returning to the surface through another pipe. ”可知潛水管的作用是把熱量傳導到下面的儲水層里。故選D。

3.

keeps the road free of snow and ice.”可知這個系統(tǒng)不僅僅是可以給建筑物供暖，還可以防止道路結(jié)冰積雪。故選B。

4.
