My favorite mode of transportation
There are a variety of world transportation, such as:by trains,by cars,by planes,by boats. These are very convenient and not expensive.
But my favorite mode is to ride a bike.
Cycling is the world's common mode of transportation, bicycles can exercise me, 3 or 4 times a week riding bikes is good for our health, it can exercise our muscles. Body fat people can lose weight by riding a bicycle. Importantly, cycling is good to our environmentally , and it does not pollutes the air, the bike will not face car traffic jams. And it will be saveing time too.
That is why I like to ride a bike, I ride a bike to school every day, so I am healthy.
