篇五： 我最喜爱的发明

What is my favorite invention?

We knew there had been many inventions at the last century, for example, electric light bulb, telephone, phonograph, mimeograph machine, automobile, airplane, atomic weapon, computer and so on. What is my favorite invention?

Personally, my favorite invention should be computer. In the old days, many scientists took much time to calculate and deal with research data, so the effective time in doing research was relatively shortened. For millions of times of calculating per second by computer, the researchers may have enough time to study more important issues. The processing of experiment results became very simple and easy. Aren’t those all evidences that the computer is one of the greatest inventions in the last century, are those?

So my favorite invention is computer.
