问题 单项选择题

为防止南方地区 * * 地面结露出现泛潮现象,以下措施中不正确的是()。

A.采用导热系数大的地面材料

B.采用导热系数小的地面材料

C.采用蓄热系数小的表层地面材料

D.采用有一定吸湿作用的表层地面材料

答案

参考答案:A

解析:南方 * * 时,气温易突然升高,使空气中水蒸气含量大大增加,而地表面温度因土壤的原因升高缓慢,使地表面温度处于空气的露点温度以下,导致空气中的水蒸气在地面凝结出现泛潮。若采用导热系数大的地面材料,将使泛潮更严重。

Father was a hardworking man who delivered bread as a living to support his wife and three children. He spent all his evenings after work attending classes, hoping to improve himself so that he could one day find a better paid job. Except for Sundays, Father hardly ate a meal together with his family. He worked and studied very hard because he wanted to provide his family with the best that money could buy.

Whenever the family complained that he was not spending enough time with them, he reasoned that he was doing all this for them. Though he often longed to spend more time with his family, he weighed his contribution to his family above everything else.

The day came when the examination results were announced. To his joy, Father passed, and with distinctions too! Soon after, he was offered a good job as a senior supervisor which paid handsomely.

Like a dream come true, Father could now afford to provide his family with life’s little luxuries like nice clothing, fine food and vacation abroad.

However, the family still did not get to see Father for most of the week. He continued to work very hard, hoping to be promoted to the position of manager. In fact, to make himself a worthily candidate for the promotion, he took another course in an open university.

Again, whenever the family complained that he was not spending enough time with them, he reasoned that he was doing all this for them. Though he often longed to spend more time with his family, he weighed his contribution to his family above everything else.

Father’s hard work paid off and he was promoted. Happily, he decided to hire a maid to relieve his wife from her domestic tasks. He also felt that their three-room flat was no longer big enough. It would be nice for his family to be able to enjoy the facilities and comfort of a condominium.    Having experienced the rewards of his hard work many times before, Father resolved to further his studies and work at being promoted again. The family still did not get to see much of him. In fact, sometimes Father had to work on Sundays entertaining clients.

Over again, whenever the family complained that he was not spending enough time with them, he reasoned that he was doing all this for them. Though he often longed to spend more time with his family, he weighed his contribution to his family above everything else.

As expected, Father's hard work paid off again and he bought a beautiful condominium overlooking the coast of Singapore. On the first Sunday evening at their new home, Father declared to his family that he decided not to take any more courses or pursue any more promotions. From then on he was going to devote more time to his family, and it was a promise.
