We always inspire ourselves with asome inspiring words, such as: faster, higher or stronger! These words usually came from some successful examples. Among them, the invention of trains are mentioned a lot. When the people who laught at the first train that ran slower than a horse, they wouldn't believe that a trin's speed can reach up to over 350 kilometres per hour one day. Some people who alway tell others to protect the environment, but think that gas-powered cars are the best choice. They refuse to try an electric car which is thought to be a toy in their minds. They can tell a lot of disadvantages of electric cars, though they never drived one of them. They just live in their world and can't accept the other things. They are really like the people who laught at trains 200 years ago. Maybe electric cars are not perfect, but plenty of people try their best to improve them .When less gas was consumed, I believe that more and more people will choose electric cars and our environment will be better, too!
