【题文】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.”
