Going out by Bus
Differennt peopel like different ways of going out.I like going out by bus best.Taking a bus is the cheapest and the most friendly-environmental way of going out.Now in cities,buses are everywhere,we can catch it very easily,and it can offer us a nice service.For exampel,the seats on the bus are very comfortable,and it has conditioners on it too.What's more,it only costs us a little.So I enjoy going out by bus.
