题目要求
最近很多大城市都投放了共享单车(shared bikes)，比如摩拜单车(Mobike)、Ofo共享单车等。
由于它们方便停放，骑车也能起到锻炼身体的作用，作为代步工具很受大家欢迎。

参考词汇：
bike-sharing companies 共享单车公司
Mobike 和Ofo 是两家共享单车公司

参考范文
The shared bikes like Mobike and Ofobring 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, which causes trouble toother 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 to registeras a user, it’s a good way to connect to one’s personal credit.
 
In the end, what I want to say is to take good care of public services.
