1 . The bed should be reserved as a place for sleep，but people tend to read an iPad a lot in bed before they go to sleep．
Charles Czeisler，a professor at Harvard Medical School，and his colleagues got a small group of people for an experiment．For five days in a row，the people read either a paper book or an iPad for four hours before sleep．Their sleep patterns were monitored all night．Before and after each trial period，the people took hourly blood tests to paint a day-long picture of just how much melatonin（褪黑激素）was in their blood at any given time．
When subjects read on the iPad as compared to the paper books，they reported feeling less sleepy at night and less active the following morning．People also took longer to fall asleep on the iPad nights，and the blood tests showed that their melatonin secretion（分泌）was delayed by an hour and a half．
The researchers conclude in today's journal article that gives the rise of e-readers and the increasingly widespread use of e-things among children and adolescents，more research into the"long-term consequences of these devices on health and safety is urgently needed．"Czeisler and colleagues go on，in the research paper，to note"Reading an iPad in bed may increase cancer risk．"
However，software has been developed that can reduce some of the blue light from the screens of phones and computers according to time of day，and there are also glasses that are made to filter（过滤）short wavelengths．While they seem like a logical solution for the nighttime tech users，it needs more research．

Dear editor，
I'm sorry to occupy your precious time, and I really want to tell you anything about the problem of some people keeping too many pets nowadays. I take the problem more and more seriously for following reasons.
First of all, as it is known to people, pets make so much noise that trouble residents a lot. What's more, it is widely accepted that animal waste pollutes the environment, where makes people quite uncomfortable. Many owners like taking their pets to public place where they may frighten children or even bite people. The mostly important is that pets can spread some diseases and this has attracted much attention.
Take all these factors into consideration, I sincerely hope that I can get help from you and expect the media do something for this.
Yours truly’
Wang Lin
Although being famous might sound like a dream come true, today's stars, feeling like zoo animals, face pressures that few of us can imagine. They are at the center of much of the world's attention. Paparazzi(狗仔队) camp outside their homes, cameras ready. Tabloids(小报) publish thrilling stories about their personal lives. Just imagine not being able to do anything without being photographed or interrupted for a signature!
According to psychologist Christina Villarreal, celebrities—famous people—worry constantly about their public appearance. Eventually, they start to lose track of who they really are, seeing themselves the way their fans imagine them, not as the people they were before everyone knew their names. “Over time，” Villarreal says, “they feel separated and alone.”
The phenomenon of tracking celebrities has been around for ages. In the 4th century B．C., painters followed Alexander the Great into battle, hoping to picture his victories for his admirers. When Charles Dickens visited America in the 19th century, his soldout readings attracted thousands of fans, leading him to complain(抱怨) about his lack of privacy. Tabloids of the 1920s and 1930s ran articles about filmstars in much the same way that modern tabloids and websites do.
Being a public figure today, however, is a lot more difficult than it used to be. Superstars cannot move about without worrying about photographers with modern cameras. When they say something silly or do something ridiculous, there is always the Internet to spread the news in minutes and keep their “story” alive forever.
If fame is so troublesome, why aren't all celebrities running away from it? The answer is there are still ways to deal with it. Some stars stay calm by surrounding themselves with trusted friends and family or by escaping to remote places away from big cities. They focus not on how famous they are but on what they love to do or whatever made them famous in the first place.
Sometimes a few celebrities can get a little justice. Still, even stars who enjoy full justice often complain about how hard their lives are. They are tired of being famous already.
