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)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 Geomet 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 polluted air gathered in most households seldom built up to dangerous levels．

This passage is most probably taken from an article entitled ________
In the last few years our communications network has been growing at a very fast pace．The old fixed－line telephone has been replaced by mobile phones．Short Message Service(SMS)．e－mail and instant messaging(IM)．And there are other new ways of communicating related to the Internet, such as blogs．
A recent study in Switzerland shows the different roles that communication methods can play．Stefana Broadbent is a scientist at Swisscom, Switzerland’s largest telecoms company．She studied several hundred consumers and their reactions to telecommunications．She found people are very good at choosing the besttechnology for each situation．
“IM is used to tell you I miss you; e-mail is to organize our dinner; voice mail is to say, I'm late; and SMS to continue our talk on the way,”says Broadbent, joking a little．
Landline phones are an open channel．That means people use them to talk about non-private things．That's because other family members or colleagues have access to the phone．Mobile phones are more for adding last-minute information．SMS is used for close friends to keep in touch．It is very efficient and pri-vate．The messages are often related to personal secrets．People often use e-mail for online communication with bigger social groups．That includes ordinary friends．Or it is used for exchanging pictures, music, and other content among a social network．IM, such as MSN and QQ, is a continuous channel．Users open an instant messaging channel for the day．Then they just keep it open while they do other activities．Managing a blog is like creating your own independent club on the Internet for friends to visit．It is often the centre of a small group of friends who share the same hobbies．
