科技改變生活，這種大潮誰也擋不住。共享單車之所以能在較短的時間內掀起一股能媲美當年網約車的浪潮，足以證明它的出現是一個趨勢。
最近很多大城市都投放了共享單車(shared bikes)，比如摩拜單車(Mobike)、Ofo共享單車等。由於它們方便停放，騎車也能起到鍛鍊身體的作用，作爲代步工具很受大家歡迎。但是，各地也出現了很多毀車現象，比如刮掉車上的`二維碼(QR code)、上私鎖等。
你對這種現象怎麼看?你對共享單車公司有什麼建議嗎?寫一篇符合邏輯的英語短文，80詞左右。
參考詞彙：bike-sharing companies共享單車公司，Mobike和Ofo是兩家共享單車公司，convenience方便，register登記
參考範文
The shared bikes like Mobike and Ofo bring great convenience to people. You needn’t lock them by simply using your smart phone. They can take you where the subway and bus don’t go. And they can be left anywhere in public for the next user.
However, bad things happen. Some people damage the QR code on the bike, or use their own lock, whichcauses trouble to other users.
In my opinion, it’s difficult to turn these people’s ideas in a short time. Therefore, bike-sharing companies like Mobike and Ofo need to do something. For example, those who damage the bike should pay for their actions. Also, because people use their real name toregister as a user, it’s a good way to connect to one’spersonal credit.
In the end, what I want to say is to take good care of public services.

Bicycle Sharing
With the development of technology, bicycle sharing comes into people's lives. It becomes 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.
