共享单车（bicycle sharing）已成为时下最热的话题之一，请你就这一话题写一篇短文。内容须包括三方面：1. 共享单车蓬勃发展，成为社会热潮；2. 共享单车带来便利，但也存在问题；3. 我对解决问题的建议。
With the development of technology, bicycle sharing es into people's lives. It bees more and more popular and much news reported it. At the same time, we should see that there are some problemscaused 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 side, 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 disadvantages.
