Electric Cars

Martin Luther King had said I have a dream. Everyone has dreams, even just one dream. Have you ever dreamed that you could drive a car by yourself to travel around the world? Or when you was a child, and when you sat in a car, would you want to go around everywhere by yourself? When I was a child, I went to amusement park. I remembered I had played the electric car at that time. It was so fantastic and exciting. Because even you crashed into car of others, you are still safe. And the most important was you can drive freely in that cycle. That was fun!

Electric cars have many types and each of them has different influences. In one thing, it is for children. They are popular in amusement parks. They can make children feel fun and happy. They can make the dreams of children come true and let them satisfied. In the other thing, it is for businessman. Now that children are interested in them, then they can help operator of the amusement park to manage the park well.

However, with the development of the technology, electric cars are not only used in amusement parks. They can be applied to lives. We can easily find them on the roads.

The first trolleybus was invented by German, and electric cars enjoyed popularity between the mid-19th century and early 20th century. Nowadays, trolleybus had been used widely in the world except some European countries. They are still using trams. Shanghai began to use trolleybus in 1914. So far, trolleybuses are used widely in Beijing, Tianjin, Wuhan and such these big cities. In recent years, we increased more concerns in environmental protection.
