Unit 5 Meeting your ancestors一、阅读理解Recent months have seen a revival of the humble(普通的)bike across China, with an increasing number of people choosing pedaling(骑车)instead of driving to school, to workplaces or to do sightseeing. The introduction of bike-sharing systems, services in which bicycles are made available for shared use to individuals who do not own them and pioneered by start-ups like Ofo and Mobike, has brought the trend to a new level.Washington D. C. has one of the biggest bike sharing systems in the US with 3, 700 bikes and 440 stations. The UK, France and Germany all have growing programs. However, China, so far, outdoes(超过)them all by operating three out of four of the worlds shard bikes.People can unlock the shard bikes by simply using their smartphone. The bikes are equipped with GPS and users of Chinas versions can leave bikes anywhere in public for the next user. Theyre popular among many Chinese people as they provide an effective solution to the “last mile” problem, which refers to the final leg of a persons journey.However, the Chinese programs have also led to problems such as illegal parking, vandalism(故意破坏)and theft. In fact, these problems are also shared by bike-sharing programs abroad. Launched in 2007, Vilb is a large-scale public bike sharing system in Paris. At its early stage of operation, it also suffered from problems of vandalism or theft. By Oct 2009, a large number of Vlibs initial bikes had to be replaced due to vandalism or theft, according to The New York Times.To deal with these problems, the pany came up with the idea of encouraging people to return the bikes to stations by rewarding free time for their next rides. Now, Chinese service operators are also trying to address these problems. For example, Mobike sets a 100-point credit score for each user, with points taken in the case of bad behavior. Once a score drops below 80, bike rental is increased to 100 yuan per 30 minutes, up from 0. 5-1 yuan.1.What can we learn about bike sharing systems?A. They offer free bike rides.B.
