　　Priscilla Quchida's “energy-efficient” house turnedout to be a horrible dream. When she and herengineer husband married a few years ago, theybuilt a $ 100,000, three-bedroom home in California. Tightly sealed to prevent air leaks，the house wasequipped with small double-parted (双层玻璃的) windows and several other energy-savingfeatures. 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 asthough she had suddenly developed a strange illness.

　　Experts finally traced the cause of her illness. The level of formaldehyde (甲醒)gas in herkitchen was twice the maximum allowed by federal standards for chemical workers. Thesource of the gas? Her new kitchen cabinets and wall-to-wall carpeting.

　　The Quchidas are victims of indoor air pollution, which is not given sufficient attention partlybecause of the nation’s drive to save energy. The problem itself isn't new. ”The indoorenvironment was dirty long before energy conservation came along，” says Moschandreas，a pollution scientist at Geoment Technologies in Maryland，“energy conservation has tendedto accentuate the situation in some cases.99

　　The problem appears to be more troublesome in newly constructed homes rather than oldones. Back in the days when energy was cheap,home builders didn’t worry much aboutunsealed cracks. Because of such leaks，the air in an average home was replaced by freshoutdoor air about once an hour. As a result, the pollutants generated in most householdsseldom built up to dangerous levels.

　　This passage is most probably take from an article entitled “ ”.

　　A. Energy Conservation

　　B. House Building Crisis

　　C. Air Pollution Indoors

　　D. Traps in Building Construction

　　C要给本文一个合适的标题，就要仔细分析全文。第一段讲述奥克达想在房屋里保存能量，结果成为一场腥梦。第二段分析其原因。第三段是专家指出事情的本质是室内污染^第四段说这个问题在新建的房屋里更为突出。综合分析之后，可知文章主旨是讲室内空气污染。所以C项是正确答案。
