About thirty years ago, China was known as “the Bicycle Kingdom”. But now with the d1. of economy(经济) and technology, more and more families have had their own cars. It seems that bicycles are not u2. any more. Recently, a bike-sharing project has been introduced by some start-ups(新兴公司) like Ofo and Mobike. As a result, a large number of people choose cycling i3. of driving to schools, to workplaces or to do sightseeing.

What is the bike-sharing project? It means people can unlock the shared bikes by simply u4. their smartphones. And the bikes are equipped(装备) with GPS so that they can be left a5. in public for the next user.

Now the shared bikes are very p6. among Chinese people. They speak highly of the project because it helps s7. the “last mile” problem. Moreover, bike-sharing is not only a greener way of transportation(交通方式) but also brings a user-friendly e8. to people.

Just as an old saying goes, “Every coin has two sides. ” This project also l9. to a lot of problems such as illegal parking, vandalism(故意破坏) and theft. To deal with these problems, the companies have come up with some ideas. For example, the users will be rewarded free time for their n10. rides if he returns the bicycles to the stations .

We believe the project will go better and better if everyone can obey the rules.
