Now people travel traffic in a number of ways, such as walking, riding a bike, bus, car, etc. Different means of transportation on our life has different effects. More and more cars to make the air of the city became more and more worse, we should reduce the drive, to make our city more beautiful. People drive the biggest reason is convenient, greatly reducing the time spent on the way, but also on the air seriously polluted. Environment for our life has a great impact, we should try our best to protect their planet, protection of the environment around us. For example, reduce the use of cars to travel by bus or ride a bicycle path is short, can walk, etc.. Now, the environment pollution is more and more get the attention of people, we should start from our own, to protect environment of their own contribution to a force。

　　now it's very convenient for people to travel around .you can go by plane ,car ,train ,ship and so on .my favourite travelling method is train .because it's very safe and comfortable .you can eat and sleep during the train travelling .the most important thing is that you can see the beautiful views when the train is moving .if it's a long trip ,you can also get off the train when it arrives at a big station .there you can buy the special local food ,and stretch you legs and get some fresh air .obviously you couldn't enjoy all these by other travelling method .
