单选题
Why are mobiles so popular? Because people love to talk to
each other. And it is easier with a mobile phone. In countries like Russia and
China, people use the mobile phone in places where there is no ordinary
telephone. Business people, use mobiles when they're traveling. In some
countries, like Japan, many people use their mobile phones to send e-mail
message and access the Internet. They use a new kind of mobile phone called
"i-mode". You can even use a mobile phone to listen to music.
Mobile phones are very fashionable with teenagers. Parents buy mobile phones for
their children. They can call home if they are in trouble and need help. So they
feel safer. But teenagers mostly use them to keep in touch with their friends or
play simple computer games. It's cool to be the owner of a small expensive
mobile. Research shows that teenage owners of mobile phones smoke less. Parents
and schools are happy that teenagers are safer and smoke less.
But many people dislike them. They hate it when the businessman opposite them on
the train has a loud conversation on his phone. Or when the mobile phone rings
in a care or restaurant. But there is a much more serious problem. It's possible
that the mobile phone can heat up the brain because we hold the phone so close
to our head. Scientists fear that mobiles can perhaps be bad for your memory and
even give you cancer.
