My New Invention

张超

Hello， everyone！ Do you think there are too many car accidents and too many environmental pollution because there are more and more personal cars？ Believe it or not，recently I invented于a new car that can help to work out these problems.

The car is controlled by a computer. It can reduce environmental pollution because ituses solar energy. The direction can changeby your voice， so it is helpful in an emergency.Whats more， it can also change its size according to the number of people in it.

In my opinion， it is anuseful and important invention. Do you think so？
