     Mobile phones are everywhere in big cities. It seems that no one can live without one. Mobile phones are

a great way to stay connected with friends and family. However, it is important to remember that there are

certain times when you should not be using your phone, especially in class or at a meeting.

     If you are in class or at a meeting, you should not be sending your friends text messages or taking phone

calls. Your classmates and teacher or the people around you will not like it and will think of it as a rude

behavior.

     In the United States, people would never be allowed to use their mobile phones during class or a meeting.

If you were to send or receive a text message, you would probably be kicked out. It is very disturbing to hear

a lot of tones and ringing when people are listening to a speech or studying. There are many more rules for the

use of mobile phones in America which are to show respect for those around you.

     It's easy to understand why it is so tempting (诱惑人的) to have your phone on during class or a meeting.

hurting yourself when you do this because the people you are with in class or at the meeting will think badly

of you and will have a bad impression on you. Sending a text message also takes your attention away from

what's going on. Even worse, you may miss something important.
