Singapore, July 12-many people enjoy chewing(咀嚼) 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 streets where it made a big mess. Chewing gum also got stuck in the doors of the underground trains so that the doors didn’t close properly. This meant the trains didn’t 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.
