The sharing economy is a little like online shopping, which started in America 15 years ago. At first, people were worried about security. But having made a successful purchase from, say, Amazon , they felt safe buying elsewhere. Similarly, using Airbnb or a car-hire service for the first time encourages people to try other offerings. Next, consider eBay. Having started out as a peer-to-peer marketplace, it is now dominated by professional "power sellers"(many of whom started out as ordinary eBay users). The same may happen with the sharing economy, which also provides new opportunities for enterprise. Some people have bought cars solely to rent them out, for example. Incumbents are getting involved too. Avis, a car-hire firm, has a share in a sharing rival. So do GM and Daimler, two car-makers. In future, companies may develop hybrid models, listing excess capacity(whether vehicles, equipment or office space)on peer-to-peer rental sites. In the past, new ways of doing things online have not displaced the old ways entirely. But they have often changed them. Just as Internet shopping forced Walmart and Tesco to adapt, so online sharing will shake up transport, tourism, equipment-hire and more. The main worry is regulatory uncertainty. Will room-renters be subject to hotel taxes, for example? In Amsterdam officials are using Airbnb listings to track down unlicensed hotels. In some American cities, peer-to-peer taxi services have been banned after lobbying by traditional taxi firms. The danger is that although some rules need to be updated to protect consumers from harm, incumbents will try to destroy competition. People who rent out rooms should pay tax, of course, but they should not be regulated like a Ritz-Carlton hotel. The lighter rules that typically govern bed-and-breakfasts are more than adequate. The sharing economy is the latest example of the Internet"s value to consumers. This emerging model is now big and disruptive enough for regulators and companies to have woken up to it. That is a sign of its immense potential. It is time to start caring about sharing.

单选题
Walmart and Tesco are mentioned to______.
【正确答案】
B
【答案解析】解析：根据题干中的Walmart and Tesco定位到第二段最后一句：Just as Internet shoppingforced Walmart and Tesco to adapt，so online sharing will shake up transport，tourism，equipment—hire and more．文章提到Walmart和Tesco是为了说明下半句：网络共享经济会重组交通运输业、旅游业、设备租赁等行业。该句突出一个词online sharing，而四个选项中只有选项[B]含有这个词，故本题选项[B]“show the potential of online sharing显示网络共享经济的潜力”为答案。
单选题
. One potential problem with sharing is______.
【正确答案】
A
【答案解析】解析：根据题干“one potential problem with sharing共享经济的一个潜在问题”定位到第三段首句：The main worry is regulatory uncertainty．其中，potential problem对应main worry，故答案原文为“regulatory uncertainty管理的不确定性”。四个选项分别为：[A]difficulty in supervi—sion监管困难；[B]disruption of economy扰乱经济；[C]instability of market市场的不稳定性；[D]uncertainty of firms企业的不确定性。这四个选项中，与regulatory uncertainty接近的选项是[A]，故该项为答案。
单选题
We learn from the last paragraph that______.
【正确答案】
C
【答案解析】解析：选项[A]属于无中生有，错误。选项[B]对应该段第一句：The sharing economy is thelatest example of the Internet’s value to consumers．可见共享经济体现出互联网对于客户的价值，而非体现顾客价值，故该项错误。选项[C]对应该段第二句：This emerging model is now big and dis-ruptive enough for regulators and companies to have woken up to it．其中wake up to=realize，it指代sharing economy，故该项正确。选项[D]属于无中生有。综上所述，本题答案为选项[C]。
单选题
The best title for the text may be______.
【正确答案】
C
【答案解析】解析：主旨题可以通过各段首句提取。第一段首句：The sharing economy is a little likeonline shopping，which started in America 15 years ago．第二段首句：Incumbents are getting in—volved too．第三段首句：The main worry is regulatory uncertainty．第四段首句：The sharing econo-my is the latest example of the Internet’s value to consumers．分析：文章反复出现和讨论的关键信息是sharing economy共享经济，而提到online shopping仅仅是为了作比较，故我们可以先排除选项[A]。选项[D]原文有提到，但是没有提到soon一词，且这个词过于绝对，该项可以排除。选项[B]在原文也有体现，但是不够全面，因为第三段首句的main worry告诉我们该段主要讨论共享经济的主要问题，故选项[C]表述比较全面，即为答案。
