Have you ever posted your photos on the Internet? Would you mind if people cut part of your photo, perhaps your face, and paste（粘贴）it into other photos as a joke? Most people would not like to be made fun of in this way. However, it is not uncommon for people to find such pictures of themselves on the Internet.

We are living in an age of information explosion. People work, play and communicate with others over the Internet. However, we must always bear in mind that some people may use others personal information for unpleasant purposes. A good example of this is what happened to a 25-year-old man. He received an e-mail that appeared to be from his bank, asking for his bank details. However, after he sent his account(账户) number to the sender, he found that money was  stolen out of his bank by online criminals.

Singapore, July 12------Many people enjoy chewing gum, but in 1992 Singapore decided to make it against the law. The government said that people were not careful about throwing away used gum. Instead, they dropped it on sidewalks and on the street where it made a big mess. Chewing gum also got stuck （粘贴）in the doors of the underground trains so that the doors didn’t close properly. This meant the trains did not run on time. Singapore said that people had to give up chewing gum or pay a lot of money to the government. During the time without chewing gum, the streets and underground trains of Singapore were clean.

   Now the government of Singapore is changing the rules a little. Some dentists say that chewing sugarless gum can help take care of people’s teeth. Now the government says that people will be able to buy special kinds of gum at drugstores for health reasons. Other kinds of gum are still not allowed.
