For centuries, men at sea have told stories about their experiences of seeing sea monsters like sea snakes and big whales．These stories are often considered as folk tales（民间传说）rather than real experiences．However, the large number of sightings and the use of modern technology are changing this attitude, making us wonder if those men were telling real experiences．
The following are some of the most well-known cases bout sea monsters living in the oceans．On August 6, 1848, in the Atlantic Ocean, seven men reported that they saw a creature about 60 feet long．The creature’s body was dark brown in colour except for its white throat area．The creature was swimming at a speed of 15 miles per hour with its head above the water．
In 1961, Mrs Stoudt and her sister were walking with their children along a strait in Washington D．C．when they saw something like a tree branch in the water．As the object moved closer to them, they saw a creature, which had a snake -like head and 3 humps（峰）．They said it looked like some sort of dinosaur．Then it moved even closer to them．Its frightening look made one of Mrs Stoudt’s children cry．
On December 12, 1964, French photographer Robert Serrec was having a holiday in Queensland, Australia．He was out off the coast in small boats with his family and friends．Suddenly, they noticed a creature, about 75-80 feet long．They described it as a tadpole-like（像蝌蚪的）creature with a snake-like head．They took pictures of the creature before it swam off．

China's bike-sharing has exploded from nothing about a year ago into a transport phenomenon in major cities. Just by scanning the QR code（二维码）that appears behind the seat,one can unlock a shared bicycle.Once the service has finished,the user blocks the bike and the total is charged to his mobile account.The process lasts less than 30 seconds and costs no more than one penny.By the way,there are still no fixed places to find or leave a bike,although areas such as university campus,and metro or bus station are preferred.
Many young people believe shared bicycles have many advantages.They are not expensive to rent,they do not have to be protected from thieves,and there is no need to repair them.You just have to change them for another one. They are also environment friendly and lower the use of cars,which also helps to relieve traffic.In fact,it is considered an awesome combination of technology and tradition.
Since they appeared,shared bicycles have raised a lot of dust.There is no doubt of the benefits but the disadvantages cannot be ignored.Many problems related to shared bicycles have emerged.It is due to bad behavior from some users who always want to seize the bicycles,but also because of the mess that has been created since one can leave the bicycle anywhere,which is against public urban order management.There are so many poorly parked bikes that sometimes they end up blocking streets.
In Xi Luoyuan,Beijing,the "Civilized Use of Bicycles" campaign has been launched.In addition to having 40 officially permitted stops,there are also clear signals to lead users to these stops.A team of supervisors keep order in the area.This is the first area that is part of an official system to manage bicycles.The purpose of this campaign is to solve the mess that the popularity of shared bicycles is causing in Beijing,both with the participation of companies and the users.If the pilot plan works out well in Xi Luoyuan,it will be extended to all of the cities in China.
