《[素材]what do you think of Doyouthinkisusefultohav_》
Why?First, it spoils environment. Its an environmental pollution. Then, cars are very expensive, most of people cant afford to pay such large money. If you say the car is very fast,it can help us arrive some places quickly,I ll tell you you also can take a bus . The tickets of the bus are very cheap. Last, cars need petrol. There isnt much petrol in the earth, and petrol is expensive, too.
I dont think it is useful to have a car in a city.Lets keep the air clean, dont buy cars.Lets go to work by bus
