In January Cathy was walking through a mall, texting on her phone. She wasn't watching where she was going, so she fell into a fountain! Luckily only her pride was hurt—she quickly climbed out and walked away. But the embarrassment didn't end there. Her accident was caught on mall cameras and posted on the Internet. The video was viewed almost 2 million times and received national attention. Cathy was angry and ashamed. But she learned her lesson: Texting while walking is dangerous. “I could have been walking into a bus, a car... anything，” she said.
Cathy may be famous for her mistake, but she isn't the only one who's taken a tumble while texting. Many people visited hospitals for similar reasons. They were walking and texting or talking on cellphones when, suddenly, a wall appeared! There were cuts, broken bones and worse.
When they are texting, people walk more slowly. They weave back and forth and don't notice other people around them. And texting isn't the only thing people do on their phones while walking. They play games, answer emails and use applications as well. Trying to do these things while walking may be dangerous, but people do it anyway. Some think it should be illegal, but others think this kind of law would be hard to enforce (实施). Too many people want to keep using their phones while they walk.
In the worst cases, people have died by accidentally walking into traffic while texting. Would anybody walk down the street with their eyes closed? Probably not, but texting is nearly the same thing. It only takes one quick glance to send a text or check an email. In that moment，a little typing could cause a lot of trouble.
