Do you know how to use a mobile phone without being rude to the people around you? Talking during a performance irritates (激怒) people. If you are expecting an emergency call, sit near the exit doors and set your phone to vibrate (振动). When your mobile phone vibrates, you can leave quietly and let the others enjoy the performance. Think twice before using mobile phones in elevators, museums, churches or other indoor public places— especially enclosed spaces. Would you want to listen to someone's conversation in these places? Worse yet, how would you feel if a mobile phone rang suddenly during a funeral? It happens more often than you think. Avoid these embarrassing situations by making sure your mobile phone is switched off. When eating at a restaurant with friends, don't place your mobile phone on the table. This conveys the message that your phone calls are more important than those around you. Mobile phones have sensitive microphones that allow you to speak at the volume you would on a regular phone. This enables you to speak quietly so that others won't hear the details of your conversations. If you are calling from a noisy area, use your hand to direct your voice into the microphone. Many people believe that they can't live without their mobile phones. Owning a mobile phone definitely makes life more convenient, but limit your conversations to urgent ones and save the personal calls until you are at home.

He grew very angry when he found his money was(steal)______.

When you open your electronic mail, you may find information about how to buy medicine, cheap airline tickets, books, computer products, and so on. There may also be offers for investment deals, bank loans and special holidays. However, to many computer users, this use of electronic spam to sell products has become a major problem as it makes computer communication more difficult. Many companies that want to send a great deal of advertising at the same time might use the services of a "spammer". A spammer is a person or company that uses computers to send out millions of copies of the same sales information. Spammers get people's e-mail addresses from websites, news groups and "chat rooms" where people send messages to each other. Most spam is sent by companies that are trying to get you to buy their products. Some of these are honest companies that may offer good products or services for fair prices. These companies can offer their products for a cheaper price than you might find in a store. However, much of the spam on the Internet is sent by criminals(罪犯) who are trying to sell products that do not exist or offer services they will not provide at all. What they are only interested in is stealing your money. When you answer their spam you find you are expected to send them money and receive a gift. If you just follow what they ask you to do without any consideration, it is likely that you will be cheated and lose some money.
