【正确答案】 Bicycle Sharing
As is shown in the picture, a boy is looking at several shared bikes from Mobike, ofo, Ubike and Xiaoming, not knowing which one to choose. The picture reflects that 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. Moreover, people can park the bike almost anywhere they like.
However, along with its rapid development and great convenience, bicycle-sharing system also brings some problems, including random parking, vandalism and possession of shared bikes, etc. On the whole, its management is not perfect.
To solve these problems, there are some measures for the authorities 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. Lastly, urban transportation system should be upgraded and improved to accommodate automobiles, bikes and pedestrians.
