What Is Your Favorite Transportataion?
　　Nowadays with the rapid development of economy,more and more people are having free money to buy a private car of their own.Much more severe pollution and transportation issues are coming along with it.
　　Actually,there are various choices for transportation means,like walking,riding a bike,taking a bus,etc.Among them,the worst way,I think,is driving a car.We all know that private cars are taking up quite a lot of room either when it comes to parking or driving on roads,which is exactly why we are having so many traffic jams in big cities.Private cars are not only making traffic jams,but also are letting out exhaust gas,which is bad for both the environment and people's health.
For the sake of personal health,environmental protection and energy saving,I believe the best way of transportation would be riding a bike.There would be no exhaust gas coming out while riding a bike.But if you're in a hurry,you can always take a bus instead.
