共享單車在各大城市亮相後，很多曾經出門就開車的人改變了他們的出行方式，路程較短或是交通擁堵時，他們更喜歡選擇共享單車，按他們的話說是既方便快捷又綠色環保。上路汽車的.減少，尾氣排放量減少，自然也就減少了對空氣的污染。

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 problems caused 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.

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, which causes 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 to register as 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.
