Bitwalking is an invention by a small company in London. To make people walk more, this new app on the mobile phone is paying people, which is based on(在…基础上)their daily walking steps.

With this app, walkers can earn one "Bitwalking dollar" for about 1000 steps (about 8 kilometers). Three bitwalking dollars can be earned by one person per day at most. The money people earned can be spent on online shopping sites(地点)or exchanged for cash(现金).

One idea behind the app is to make people healthier. But the designers also have another goal: to improve people's lives. In poor countries, people have to walk far to work, or to school, or simply to collect water. Workers in the countryside earn less than one dollar a day. By walking around with the Bitwalking app, they could earn three times more.

The company has also set up Bitwalking centers in some poor areas. At the centers, local people will learn how to use the Bitwalking dollars or trade(交易)them for cash. Bitwalking is really helping to change lives.

1.How many Bitwalking dollars can one people get at most every day?

2.What is the goal of Bitwalking?

3.Do you think we middle school students can use this app? Why?
