Not all memories (记忆)are sweet. Some people spend all their lives trying to forget bad experiences. Wars and traffic accidents can leave people with terrible physical and mental scars. Often they appear again in dreams.
Now American researchers think they are close to developing a pill(药丸), which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce（减少）, or possibly erase(抹去) the effect of sad memories.
In November, some scientists tested a drug(药) on people in the US and France. The drug stops the body producing chemicals(化学品) that fix memories in the brain. So far the research has suggested that only the mental effects of memories may be reduced, not that the memories are erased.
The research has caused plenty of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories.
“Some memories can destroy(破坏) people’s lives. They come back to you when you don’t want to have them in a dream. They usually come with very sad feeling.” said Roger Pitman, a scientist of psychiatry at Harvard Medical School. “This could relieve(减轻) a lot of that suffering.”
But those who are against the research say that it is very dangerous to change memories because memories give us our identity(特质). They also help us all get away from the mistakes of the past.
“All of us can think of bad events in our lives that were terrible at the time but make us who we are. I’m not sure we want to erase those memories,” said Rebecca Dresser.

There are more than 3000 languages in the world today, but only about ten are major languages of the world. Among them English is the most popular.
More than 350 million people speak English as their first language. Major English-speaking countries are Britain, Australia, New Zealand, Canada and the USA. Another 400 million speak it as a second language. No one knows how many people speak English as a foreign language. They usually learn English as a school subject instead of learning it from their parents. Chinese is the only language with more speakers than English. This is because of the large population of China.
English is the language for a better understanding between peoples of the world. It is also the language for business and science. Nearly half of the business deals in Europe are done in English, and more than half of the science magazines are in English. English is widely used in the world’s computer network. And children should begin with English when they learn how to use computers. Through the English language peoples of different countries are able to work together and make things even better.
