Can you guess in which city the idea of “shared bikes” was born
The City of Bicycles.
Amsterdam
Why

1. People in Amsterdam have been enjoying the benefits of cycling for years. The idea began about 50 years ago, and was first known as "white bikes". Amsterdam is a good city for cycling because it's flat and therefore convenient for bikes.
阿姆斯特丹人多年来一直享受骑自行车的好处。这个想法始于大约50年前，最初被称为“白色自行车”。阿姆斯特丹是一个骑自行车的好城市，因为它地势平坦，骑自行车很方便。

1. There are also plenty of places for bicycle parking and most streets in the city centre have a bicycle path.

还有很多地方可以停放自行车，市中心的大多数街道都有自行车道。由于骑自行车方便，阿姆斯特丹非常受骑自行车者的欢迎—令人惊讶的是，每10次出行中有38%是骑自行车出行的。有些人甚至称阿姆斯特丹为“自行车之城”。

2. Where did the idea of "white bikes" come from In the 1960s, a group of cycling fans came up with an idea. They believed that it would be better for everybody if cars weren’t allowed in the city centre and only bicycles were. They were hopeful that this would help to save energy, reduce pollution and provide free public transport.
“白色自行车”的概念从何而来 在20世纪60年代，一群自行车爱好者想出了一个主意。他们认为，如果市中心只允许自行车通行，而不允许汽车通行，对每个人都会更好。他们希望这将有助于节约能源，减少污染，
并提供免费的公共交通。
想出，提出（计划，想法等）
v.允许 allow sb. to do sth.
2. The group painted hundreds of bicycles white and placed them in many areas around Amsterdam for people to use. Anyone was allowed to take them and use them for short journeys. People would leave the bike in the place where they finished their journey, so that someone else could then take it and use it from there. Soon after, however, problems came up and the "white bikes" all disappeared - thieves stole them all in a matter of weeks!
该组织将数百辆自行车涂成白色，并将它们放置在阿姆斯特丹周围的许多地方供人们使用。任何人都可以乘坐它们进行短途旅行。人们会把自行车放在他们结束旅程的地方，这样其他人就可以从那里拿走并使用它。然而，不久之后，问题出现了，“白色自行车”都不见了——小偷在几周内把它们都偷走了!

Young people like the students will determine how successful bike-sharing will be in the future by deciding whether or not and how much they want to use it.
It can also mean that whether or not bike-sharing can exist successfully depends on each individual . Everyone has to take the responsibility to take care of bike-sharing so that it can last longer and help people better .
