At present, almost everyone has a mobile phone, but have you ever thought that cell phones be bad for your health? A study shows that heavy mobile phone use may cause hearing loss(失聪). This study shows that people who use cell phones for about an hour a day have a time hearing some similar sounds, especially in their right ears. It is getting harder for to tell the difference between the sounds of“s”and“f”,and“t”and“z”. Researchers studied 100 people who used cell phones and them with 50 people who did not. The study lasted for 12 months. What the researchers found was that cell phone users had more hearing than those who did not use cell phones. Besides this, our ears have many little inside them. Too much noise will cause these hairs to get weak and die. When these hairs die, it affects our ability to listen. However, cell phone users don’t care too much this study. One man said,“I’d be more worried about people who MP3 players. They put those earphones in their ears and listen to very music. I think that is more likely(更有可能的) to cause hearing loss than a cell phone.”

The family sphere (范围) used to be defined by its isolation from the public realm.
There was the public male realm (领域)of "rational accomplishment" and cruel competition,
and the private female and child-rearing sphere of home, intuition (直觉) and emotion. The
private realm was supposed to be isolated firm the realities of adult life. For both better and
worse, television and other electronic media tend to break down the difference between
those two worlds. The membrane around the family sphere is much more permeable
(可渗透的). TV takes public events and transforms them into dramas that are played
out in the privacy of our living rooms, kitchens and bedrooms.
Parents used to be the channel through which children learned about the outside world.
They could decide what to tell their children and when to tell it to them. Since children
learn to read in stages, books provide a kind of natural screening process, where adults
can decide what to tell and not tell children of different reading abilities. Television
destroyed the system that separated adult from child knowledge and separated
information into year-by-year slices for children of different ages. Instead, it presents the
same information directly to children of all ages, without going through adult filters.
So television presents a real challenge to adults. While a parent can read a newspaper
without sharing it with children in the same room, television is accessible to everyone in
that space. And unlike books, television doesn't allow us to flip (翻转) through it and see
what's coming up. We may think we're giving our children a lesson in science by having
them watch the Challenger take off, and then suddenly they learn about death, disaster and
adult mistakes.
Books allow adults to discuss privately what to tell or not tell children. This also allows
parents to keep adult material secret from children and keep their secret keeping secret.
Take that same material and put it on The Today Show and you have 800,000 children
hearing the very things the adults are trying to keep from them. "Television takes our kids
across the globe before parents give them permission to cross the street."
More importantly, children gradually learn that adults are worried and anxious about
being parents. Actually, television has also places families under a lot of stress.
