亲爱的楼主：
Bike is a popular means of transportation .It is a friendly environment
transport tool.I like riding bikes when go travelling or go shopping.Nowdays
motor cars are increasingly popular but I think it will cause a lot of damage to
us .First it will give out lots of waste gas,which will contribute to the global
warming.It is bad for our earth.Second. the number of the cars is becoming
larger and larger and the crowded traffic will certainly bring about the risk of
safety.So I think riding a bike is a better choice if we take environment into
consideration.
祝您步步高升
