Nowadays, sharing bikes has become an increasingly popular way to travel. And it brings us a series of benefits in life. First of all, the advent of sharing bikes can reduce the number of private cars and ensure the smooth flow of traffic. Secondly, it’s a green travel which greatly reduces the pollution of the environment by cars. What’s more, by cycling we can explore every corner of the city, and have a more comprehensive understanding of the city's natural history.

However, sharing bikes also produces many problems at the same time. Firstly, bad behaviors such as vandalism ['vændəlɪzəm] and private locking are often occurring across the country. Besides, it’s difficult to look for the sharing bikes which have been ridden.

For example, there have been various kinds of needle incidents in the sharing bike seat.Some people put needles in the Shared bicycle seatsout of mischief. And it is likely to hurt people. Besides,some sharing bikes are so heavy that some girls can't ride. In addition,the bicycles were randomly arranged in the streets, affecting the image of the city.

As for the cause of these problems, I think there are three reasons. Firstly, there is a lack of regulation in the government, and the plans for a bicycle parking lot are not reasonable. Secondly, the bicycle company lack the social responsibility, and ignore the consequence caused by their products. Last but least, the users lack quality.

Generally speaking, to prevent this problems worsen, government should set up laws to standardize the behaviors of the users while individuals need to improve their personal qualities .And the campany should undertake social responsibility and regulate the sharing bikes.

And there was a heavy burden on the family and the indelible pain of losing loved ones.

So how to avoid excessive drinking at parties? I have two suggestions.One is just say no before you start the party or when someone else is trying to persuade you. Another isfocusing on other games or food at parties instead of dunking.Generally speaking,You should consider the consequences of overdrinking at parties.Don't be a burden to the host and your family.
