【正确答案】
Bicycle Sharing

   Bicycle-sharing system has become increasingly popular in the city recently. A large number of shared bikes can be found and rented at a low price, which makes it very convenient for people to travel around.
   However, along with its rapid development and great convenience, bicycle-sharing system also brings some problems, including disorderly parking, vandalism and possession of shared hikes, etc. On the whole, its management is far from perfect.
   To solve these problems, there are some measures for the authorities and the public to take. Firstly, the government should implement strict laws and rules to regulate the operation and management of bicycle-sharing system. Secondly, the public should raise their awareness of using shared bikes reasonably. Last but not least, urban transportation system should be upgraded and improved to accommodate automobiles, bikes and pedestrians.
