I like cars! when seeing cars moving in the road ,i feel pround of being a human in the world.we are the owner of the world. we feel self-satisfiedwhen we invent cars.we can go for a long trip not by walk but by driving cars which are regarded as the best traffic tool.
Cars play an important role in modern society.But ,every coin has two sides. the exhaust gas pooled ty cats have become a threat to our health. of course ,i believe that our us can solve this problem perfectly!
