问题     Priscilla Ouchida’s "energy-efficient" house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $ 100,000, three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned (双层玻璃的) windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness.
    Experts finally traced the cause of her illness. The level of formaldehyde (甲醛) gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting.
    The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. "The indoor environment was dirty long before energy conservation came along," says Moschandreas, a pollution scientist at Geometry Technologies in Maryland. "Energy conservation has tended to accentuate the situation in some cases. "
    The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn’t worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom build up to dangerous levels. (262 words)
It can be learned from the passage that the Ouchidas’ house______.
选项 A、is well worth the money spent on its construction
B、was designed and constructed in a scientific way
C、failed to meet energy conservation standards
D、is almost faultless from the point of energy conservation
答案D
解析 本题属于综合推理题。根据题干中的关键词“Ouchida’s house”可以定位到文章的第一段，根据第一段中间对他们房子进行的描绘，从节约能源的角度来讲，他们的房子是建造得完美无缺的。文中Priscilla祸患不断并非因采用节能方法所造成，而是原有潜在的及后来采用新方法带来的问题才使室内空气污染问题变得严重。故D为正确答案。
