It becomes more and more popular and much news reported it. At the same time, we should see that there are some problems caused by bicycle sharing. On one side, bicycle sharing makes it very convenient of people traveling. You can find a bicycle anywhere at any time when you want to go out for a cycling, and the price of one trip is very low. It can save time for people. On the other hand, its management is not perfect. Even kids can open the lock and ride the bicycle, there is no doubt that such behavior is very dangerous. What’s more, many people deliberately break it, like throw it to the river or destroy the code above it. In my opinion we should take a developing view about bicycle sharing. It is obviously helpful to human beings as a high-tech product. The government should introduce relevant provisions to regulate this market to avoid its advantages. 范文二：My view on Bicycle-sharing Presently, in big cities like Shanghai and Guangzhou, bicycle sharing system has become increasingly popular. A large number of shared bikes can be found and rented at a low price. Moreover, you can park the bike almost anywhere you like. Urban transportation has thus been made much more convenient and even revolutionized. However, along with its rapid development, bicycle-sharing system also brings some problems, including random parking, illegal parking and so on. To solve these problems, there are some measures for the government to take. Firstly, the government could implement more strict laws and management of bicycle-sharing system. Secondly, the public should raise their awareness of using shared bike reasonably. Lastly, urban transportation system should be upgraded and improved to accommodate automobiles and bikes. To conclude, with effective and efficient measures taken, and efforts made by those involved, it can be expected that bicycle-sharing system will play a important role in urban transportation. 本文来源：https://www.wddqw.com/doc/3325690b5b8102d276a20029bd64783e09127d2a.html
