(2017·南京高三三模)请阅读下面材料，并按照要求用英语写一篇150词左右的文章。

Bike­sharing has taken off in China far faster than in any other market.The market has become flooded with new companies in recent months.The bike­sharing companies operate in a similar way.They use apps that allow users, after paying a deposit, to unlock the wheels with their smart­phones.After the journey, users can leave bikes anywhere in public and pay a little money for the use.The service is very popular as it provides an effective solution to “ the last kilometer” problem.

The promoting of the bike­sharing service is also raising questions about profitability，widespread bike vandalism(破坏)and theft，and growing government regulation.A Hong Kong man who was arrested for throwing several shared bikes into rivers said he had no regret destroying them because “the GPS devices in the bikes give away users\' personal information，such as their locations.”

【参考范文1】

The passage conveys to us the bike­sharing boom across the country，with more companies springing up in the market.The service not only brings great convenience to people，but causes some problems as well.

From my standpoint，the bike­sharing system has become an essential part of public transportation in cities and should be actively promoted.Firstly，with an increasing number of people choosing the service to get around，the number of cars on the roads will decrease dramatically，which really helps the environment and reduces traffic jams.Furthermore，this service also benefits individuals in various ways.For example，it provides locals and tourists with a convenient，cheap and healthy means of transport.Those who would otherwise use their own bicycles don\'t need to be concerned about such problems as theft，storage and maintenance.

In a word，bike­sharing is an innovative service，which relieves urban traffic pressure and brings citizens enormous benefits.And more shared bikes should be launched into the market.

The passage conveys to us the bike­sharing boom across the country，with more companies springing up in the market.The service not only brings great convenience to people，but causes some problems as well.

In my opinion，bike­sharing should not be promoted at present for the following reasons.In order to attract more subscribers，the bike­sharing companies are flooding walkways and other public spaces with hundreds of bikes in the hope of promoting their services，which brings great inconvenience to pedestrians.Furthermore，for lack of relevant regulations，some uncivilized people deliberately damage shared bikes，for example，by throwing them into rivers or piling them up randomly.A fairly high deposit fee has also been criticized in a country familiar with accessing inexpensive public services.

In conclusion，bike­sharing systems shouldn\'t be promoted before regulations and policies are put in place.The government，companies and users should all play their role in making bike­sharing sustainable and enjoyable.
