下列关于美国和巴西的叙述的是 A.均为农产品出口国  B.均为美洲国家  C.均为世界髙新技术“产业基地” D.均在西半球 答案：CIt’s reported that more and more people choose cycling instead of driving to schools, to workplaces or to do sightseeing．The introduction of Bike-sharing Plans, pioneered by companies like Ofo and Mobike, has brought the trend to a new level．People can unlock the shared bikes by simply using their smartphone．The bikes are equipped with GPS and can be left anywhere in public for the next user．They’re popular among many Chinese people as they provide an effective solution to the “last mile” problem, which refers to the final leg of a person’s journey．“In places where the underground doesn’t extend (延伸到), where it’s difficult to change from one kind of transport to another, it’s so easy to get where you want to go with Mobike,” Hu Hong, 29, told AFP．She pedals to her faraway job in Shanghai．However, the schemes have also led to problems such as illegal parking, vandalism (故意破坏) and theft．“Bike-sharing is a greener method of transportation and provides a user-friendly experience,” said Liu Xiaoming, vice-minister of transport．“But it’s a combination of online and offline business．Operators are usually strong in online services, but lack offline business experience, which causes problems．”To deal with these problems, the company 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.How can people unlock the shared bikes?A. by equipping with GPS． B.
