In the United States, many people use cell phones. But few send messages with them. Most of them don’t even like to try it. Do you find it strange?

Computers are very common in America. 小题1: Most people like using e-mails more than messages.  Sending e-mails is faster than sending messages .They don’t need to choose the letters one by one . It can save more time . And they like talking on the phone. They don’t feel good when “talking ”by sending messages to each other.

Another reason is to save money. Americans are excited about new cell phones .But they think a lot before they buy. So many people’s cell phones are still very old . They can’t send messages.

小题2:In the U.S. ,people call for free from 7(or9)o’clock in the evening. But if they send messages ,they still have to pay. A message costs about 10 cents . It is too much.

小题3:It is also bad manners to greet by sending messages in American. Americans are happier to get cards from their families or friends.
