Advantages We can communicate with friends Listen to the music See films & watch news Play games Do shopping Save a lot of time Do a lot of useful things

Disadvantages Some people especially the teenagers abandon (沉迷于) themselves to the computer games and chatting on the Internet. As a result, they have little time to study. Some people use the computer wrongly. If you spend too much time on it, it will do harm to our health.

Conclusion There is no doubt that computer has two sides, too. If we make good use of it, it will make our lives more colorful and convenient. But don’t lose yourself in playing computers. Just remember: Keep fit, study well and work hard.

I was born in 1642 in France. In 1822, I was built as an analytical machine. In 1936, my real father, Alan Turing, described how computers could be made to work in a book and solved any mathematic problem by building a universal machine. People were surprised at my artificial intelligence. At first, I was the size of a large room. As time has gone by, I have been made smaller and smaller. In the 1960 s, I got new transistors. My memory became larger and larger, and I got cleverer and quicker. I could share information with others and talk to each other by a net. It was in the 1970 s that my family and I have been used by billions of people. I am happy that I have truly been built to serve human race since my birth.
