2、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。但是，各地也出现了很多毁车现象，比如刮掉车上的二维码(QR code)、上私锁等。

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’spersonal credit.
In the end, what I want to say is to take good care of public services.
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 bybicycle 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 forpeople. On the other side, its management is not perfect. Even kids can open the lock and ride the bicycle, there is no doubt thatsuch 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 obviouslyhelpful to human beings as a high-tech product. The government should introduce relevant provisionsto regulatethis market to avoid its disadvantages.
My Views on Bicycle-sharing
Presently, in big cities like Shanghai and Guangzhou, bicycle-sharing system has become increasinglypopular. 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 transportationhas thus been made much more convenient and even revolutionized.
However, along withits rapid development, bicycle-sharing system also brings some problems, including random parking, vandalism and possession of shared bikes, etc.
To solve these problems, there are some measures forthe authorities to take. Firstly, the government could implement more strict laws and rules to regulatethe operation and management of bicycle-sharing system.Secondly, the public should raise their awarenessof using shared bike reasonably. Lastly, urban transportation system should be upgraded and improved to accommodate automobiles, bikes and pedestrians.
To conclude, a sensible attitude should be held toward bicycle-sharing program. With effectiveandefficientmeasures taken, and efforts made by those involved, it can be expected that bicycle-sharing system will play a contributiveand constructive role in urban public transportation.
About three decades ago, China was known as the “Bicycle Kingdom”. But the two-wheeled mode (方式) of transport’s popularity began to fade, with many bikes soon replaced by their fuel-powered competitors.
But recent months have seen a revival (复兴) of the humble (普通的) bike across China, with an increasing number of people choosing cycling instead of driving to schools, to workplaces or to do sightseeing. The introduction of bike-sharing schemes, pioneered by start-ups (新兴公司) like Ofo and Mobike, has brought the trend to a new level.
According to data compiled (编制) by iResearch Consulting Group, the first week of this year saw 5.85 million active users of Mobike while Ofo had 1.4 million active users.
People can unlock the shared bikes by simply using their smartphone. The bikes are equipped with GPS and can be left anywhere in public for the next user. They’re popular among many Chinese people as they provide an effective solution to the “last mile” problem, which refers to the final leg of a person’s journey.
