In what may be the most terrified shower news since Alfred Hitchcock’s “Psycho,” a study says shower heads can hide tiny bacteria that come spraying into your face when you wash. People with normal immune systems have little to fear, but these bacteria could be a concern for those with AIDS, people who are undergoing cancer treatment or those who have had a recent organ transplant.

Researchers at the University of Colorado tested 45 showers in five states as part of a larger study of the microbiology of air and water in homes, schools and public buildings. They report their showers findings in Tuesday’s edition of Proceedings of the National Academy of Sciences.

In general, is it dangerous to take showers? “Probably not, if your immune system is not compromised in some way,” lead author Norman R. Pace says. “But it’s like anything else---there is a risk associated with it.”

The researchers offer suggestions for caution, such as getting all-mental shower heads, which microbes have a harder time clinging to.

 Still, it is hard to clean the shower heads, the researchers note, and the bacteria come back even after cleaning. People who have filtered(过滤的) shower heads could replace the filter weekly, added co-author Laura K. Baumgartner. And, she said, baths don’t splash bacteria into the air as much as showers.

Indeed, studies by the National Jewish Hospital in Denver suggest increases in infections in the lungs in the Untied States in recent decades from species like M.
    Symptoms of infection can include tiredness, a persistent, dry cough, shortness of breath, weakness and “generally feeling bad,” he said.

Shower heads were sampled at houses, apartment buildings and public places in New York, Illinois, Colorado, Tennessee and North Dakota.

 The researchers sampled water flowing from the shower heads, then removed them, wiped the interiors of the devices and separately sampled water flowing from the pipes without the shower heads.

 By studying the DNA of the samples they were able to determine which bacteria were present.

“Scotty!” Mr. Brown, my Year 11 English teacher, called me by my nickname (绰号) across the classroom. His eyes were bright and a secret   36   was half hidden behind the beard.

Once he finished joking over my unbearable   37  , I realized he was going to read my story aloud to the class. I turned red, feeling at once both embarrassed and   38  . I had my very   39   reading audience! Though my classmates were a ‘passive audience’, it didn’t weaken my feeling of being   40  .

After that, I came to   41   those Year 11 English classes. Throughout school I had always studied hard and achieved well in my school subjects. But creative   42   was a passion, and it was not an assignment, but a way of understanding the world and of   43   my thoughts and feelings about events and attitudes.

Mr. Brown was the first to   44   me for my writing so openly. My scores were always 19/20 or 20/20. My stories were often read out to the class. He even   45   one with the respected Head of English teachers, which was the most   46   part that is impressed on my memory. But   47   that, he offered a belief in me that no other teacher had.

My school   48   often stated, ‘Candice is a quiet achiever.’ I thought it was meant as a(n)   49   for being hard-working. I was someone that no one really   50   before, but Mr. Brown managed to   51   all that by bringing me to the attention of the world. Though it was the relatively   52   world of school, it put the seed of belief in myself that some day I could be an   53   person rather than the person who faded into the background.

I   54   touch with my teacher long ago, as we do when we move away from the school system and enter life. I wish I could tell him now how much he   55   me.

　　During my ninth-grade year, I suffered from “anorexia nervosa”. It was not enough to be thin. I had to be the thinnest. Now, however, fully recovered, I can reflect back and realize that my wishes were more complex than fitting into size five pants. Many of my hidden emotions were related to my relationship with my father. As I was growing up, his work always came first. Sometimes I would not see him for up to two weeks. Not only did he devote his whole self to his work, but he expected me to do the same (“You cannot get anywhere unless you go to the best universities!”). Though, consciously, I never felt pressure to please him, I began dieting after the first time he told me I looked fat.　　

　　At the time, all I knew was that I had to be thin―thinner than anyone else. Every month my father went to Europe for a week or so and on the days he left, sorrow and emptiness swallowed me: Daddy was leaving. Then, I turned to focus on a mysterious weakness―a helpless childlike emotion that came from starving. I liked to know that I needed to be taken care of; maybe Daddy would take care of me.

Now, two years later and thirty-eight pounds heavier, I have come to realize that I cannot change my father’s inability to express his feelings. Instead, I must accept myself. I know that I am a valuable person who struggles to achieve and accomplish. But I cannot struggle solely for others. By starving, I attempted to gain pride in myself by obtaining my father’s approval or acknowledgment of my value as a person. But the primary approval must come from me, and I feel secure now that I can live with that knowledge safely locked in my mind.
