23．　　Bike-sharing has swept across China, with a number of people choosing bike riding instead of driving. The bike has GPS on it and can be easily unlocked with a smart phone. Bike﹣sharing allows people to borrow a bike from one place and return it at another place easily.
　　In some cities, we can see more and more people riding this kind of sharing bikes. It's very easy to use the bikes if you have a smart phone. First, you have to download such an APP on your smart phone. Then what you need to do is to find a nearest bike through the APP, scan the QR code (二维码) on the bike. You will find the bike can be unlocked itself.
　　Then you can enjoy your trip. What's more, you can easily find one and never worry about where to park it. The cost of riding depends on the time that you spend. Normally, every hour you ride, you need to pay one yuan. It doesn't cost so much, does it?
　　At the same time, some people park the bikes in their own homes. Besides, some people don't value the bikes. Now service companies are trying to solve the problem like being stolen.
Technology and science have changed our social lifestyles. And we also hope that people can not only enjoy it but also put it to good use.
