The details, such as the topic of it, and my arrangements about this debate can be listed as follows. Initially, as for the topic, we may focus on ^v^Bicycle sharing^v^. Here are the reasons. On one hand, bicycle sharing makes it very convenient for people to travel, and the price of one trip is very low, which every one can afford. On the other hand, its management is not perfect. Even kids can open the lock and ride the bicycle, and no one can deny the fact that such behaviors is very dangerous. Finally, the debate will discuss whether bicycle sharing is a blessing or a curse. Participants can be divided into two groups to present their views alternatively.
