阅读下面短文，根据要求完成下列各题。

On September 22, 2013, Huai’an announced(宣布) its own bike-sharing system to the public. By today, Huai’an has had 150 stations with 3,600 docking points. About 3,300 public bikes are only offered to people who have a Citizen Card(市民卡).

The public bike-sharing system is not rare in the world. Till April 2013 there were about 535 bike-sharing programmes around the world.

The name is quite different around the world. In Montreal, Canada, the public system is called BIXI; in Chicago, USA, its name is Divvy. However, there hasn’t been a name for the system in our city. Huai’an aims to be an international city in northern Jiangsu, so it needs to be given an English name.

When you want to ride the bike, the first hour is free. If you use the bike between 61-120 minutes, 1yuan; 121-300 minutes, 2 more yuan; over 5 hours, 5more yuan. So you can return the bike within 1hour to any station and rent(租) again to save money.

At present, there are no rules about how many times you can use the system each day. Go to a station and have a try now!
