问题     Bedbugs, stealthy and fast-moving nocturnal creatures that were all but eradicated by DDT after World War Ⅱ, have recently been found in hospital maternity wards, private schools and even a plastic surgeon’s waiting room. Bedbugs are back and spreading like a swarm of locusts on a lush field of wheat. "It’s becoming an epidemic," said Jeffrey Eisenberg, the owner of Pest Away Exterminating, a business that receives about 125 bedbug calls a week, compared with just a handful five years ago. Last year the city logged 377 bedbug violations, up from just 2 in 2002 and 16 in 2003. Since July, there have been 449. "It’s definitely a fast-emerging problem," said Carol Abrams, spokeswoman for the city housing agency.
    In the bedbug resurgence, entomologists and exterminators blame increased immigration from the developing world, the advent of cheap international travel and the recent banning of powerful pesticides. Other culprits include the recycled mattress industry and those thrifty citizens who revel in the discovery of a free sofa on the sidewalk. Unlike mice and roaches, which are abetted by filthy surroundings, bedbugs do just fine in a well-scrubbed home. And they don’t dwell just in mattresses and box springs: any wall or floor crack--the thickness of a playing card--can accommodate a bedbug. The modern bedbug is immune to insecticides, and setting off a cockroach bomb in the bedroom will only scatter them farther afield. And because they are active only at night, many people don’t discover them until their population has grown into the hundreds, or even thousands. Exterminators recommend bagging and washing every bit of clothing and fabric in the room and taking apart bureau drawers and bed frames in preparation for the application of four kinds of chemicals. The process often needs to be repeated.
    Worst of all, bedbug sufferers say, is the stigma of living with an insect that feeds on blood--though it does not transmit disease--and leaves behind a trail of red bumps. In interviews with more than a dozen bedbug sufferers, only a handful would speak on the record, saying they feared the condemning glares of neighbors or the shunning of co-workers. A bedbug infestation, many say, puts a strain on relationships, all but ruling out staying the night. Kellianne Scanlan, 30, a hairstylist who lives in Washington Heights, has been living like a nomad since last month. "My life has become all about bedbugs." she said. To calm her friends and to ensure that she does not spread the bugs, she takes an extra set of clothing and changes when she arrives at their homes for overnight visits.
By mentioning Kellianne Scanlan the author wants to tell us ______ .
选项 A、the psychological damage is probably the worst thing about bedbugs
B、bedbugs have led to severe result of breaking the love and relationships
C、the sufferers’ feeling of inconvenience to have bedbugs living in their home
D、changing clothes frequently is helpful to exterminate the spreading of bedbugs
答案A
解析 文章最后一段举了Kellianne Scanlan的例子：由于家里出现了臭虫，自从上个月以来她过得就像个流浪者；在朋友家过夜时不得不多准备一套换洗衣服，造成了精神上的痛苦。那么我们来看四个选项。A“精神上的伤害”也许是臭虫问题中最严重的后果。臭虫在干净的地方都可以生存，所以经常换衣服并不一定能够防止臭虫的传播，因此正确答案是A。
