Read the passage about the invention of Computer.
Computer
Computers are becoming more and more important in our daily life. Do you know when the computer was invented The computer was invented in 1946. At that time , it was huge. With the development of science and technology, the computer has grown smaller. Now there are many kinds of computers, such as personal computers and laptops. The computer is a very useful tool in our life.
For example , it can send some messages to foreign friends by e-mail. What’s more , it can share information with others through the World Wide Web. We can also listen to music or play the game on computers. It makes us relax.
It’s hard to imagine what our life would be like without computers. I think computers will be more convenient and they are going to change our life completely in the near future.
It is often difficult to decide on the inventor of certain inventions. This is because sometimes a few people may ______ things which are nearly the same. It’s hard to tell who came up with the idea first. Some inventions can also lead to other inventions _____________. So some people _____ whether the inventor came up with the idea himself or herself. They think that the inventor used someone else’s idea to create his or her invention. That is why books or _______ usually _______ more than one inventor when giving information about inventions.
