9月9日，甲、乙签订一房屋买卖合同，合同约定如果甲能顺利出国就将房屋卖给乙并于出国前办理过户登记，并约定好了价格。由于甲的出国手续还未办妥，所以合同约定在合同签订之日起一周内由甲协助乙先向登记机构申请办理预告登记。9月11日两人在登记部门办理了预告登记。11月15日甲办妥出国手续后，遇到高中同学丙，丙知道甲要出国当即出了比乙更高的价格要买甲的房子，二人一拍即合，当天就去登记部门办理过户登记，乙对此不知情。下列说法正确的是：

A．如果11月15日登记部门办理了过户登记，丙取得房屋的所有权

B．即使11月15日登记部门办理了过户登记，丙也不能取得房屋的所有权

C．预告登记已经失效，丙取得房屋的所有权

D．乙只能请求甲承担违约责任，不能请求甲交付房屋

     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 rub 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 (蓄水层) into

which several heat exchangers (交换器) 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.

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 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.
