Reading is an activity people enjoy a lot in their free time. Some like reading newspapers, and others enjoy novels or comic books. I like reading about the lives of great poeple. This always gives me a lot of ideas on how to make my own life better.

Great people are remembered not because they were handsome or beautiful, but because they did not give up when their lives were difficult. They used every opportunity to change their lives and make the world better.

One good example is Orville and Wilbur Wright, the two brothers who invented the airplane. The plane has made the world into a small village. Hard work, not good luck, is the reason why the Wright Brothers could invent this convenient machine and become remarkable people. Today we wtil remember them when we see planes in the sky.

When I feel sad, stories of great people always help me feel better. This is why I enjoy reading about great people’s lives.
