Many people prefer text messages(短信)to actually talking. Almost overnight, text messages have become the preferred form. of communication for millions. But even as industry calculations show that Americans are now using mobile phones to send or receive more text messages than phone calls.

" In the latest fight against text messaging, the California Public Utilities Commission announced an emergency measure on Thursday temporarily banning the use of all mobile devices by anyone at the controls of a moving train.

A California lawmaker is also seeking to ban text-messaging by drivers, a step already taken by a handful of other states. "We have had far too many tragic incidents around the country that are painful proof that this is a terrible problem. " said Joe Simitian, who wrote the California law requiring drivers who are talking on a cell phone to use hands-free devices.What can we know from the second paragraph?A．Text messaging may result in many accidents.B．Text messaging has caused most of the accidents recently.C．Many people are going to text messages instead of telephoning.D．The government is now trying to stop text messaging.
