单选题Strange things happen to time when you travel, because the earth is divided into twenty four time zones, one hour apart. You can have days with more than twenty -four hours, and weeks with more or fewer than seven days. If you make a five - day trip across the Atlantic ocean, your ship enters a different time zone every day. As you enter each zone, the time changes one hour. Traveling west, you set your clock back; traveling east, you set it ahead. Each day of your trip has either twenty - five of twenty - three hours. If you travel by ship across the Pacific, you cross the international date line. By agreement, this is the point where a new day begins. When you cross the line, you change your calendar one full day, backward or forward. Traveling east, today becomes yesterday, traveling west, it is tomorrow!

单选题How could anybody dislike the notion of fairness? Everything is better when it is fair: a share, a fight, a maiden, or a game. Even defeat sounds more attractive when it is fair and square. For the British fair play is especially important: without it, life isn't cricket. Their country becomes quite pleasant when the weather is fair, though unfortunately it rarely is. And these days fair-trade goods crowd their supermarket shelves. Fairness is not only good, but also moderate, which is another characteristic that the British approve of. It does not claim too much for itself. Those who, on inquiry, admit that their health and fortunes are fair-to-middling navigate carefully between the twin dangers of boastfulness and ill-temperedness, while gesturing in a chinup sort of way towards the possibility of future improvement. Fairness appeals to the British political class, for it has a common sense down-to-earthiness which avoids the grandiosity of American and continental European political discourse while aspiring to do its best for all men--and of course for maidens too, fair and otherwise, for one of its virtues is that it does not discriminate on grounds of either gender or skin colour. Not surprising, then, that Britain's government should grab hold of the word and cling to it in the buffeting the coalition has had since the budget on June 22nd proposed higher taxes and even sharper spending cuts. "Tough but fair" is what George Osborne, the Conservative chancellor of the exchequer, called the cuts he announced. "It is going to be tough, but it is also very fair," said Vince Cable, the Liberal Democrat business secretary. At last, something they could agree on. "Fairness" suits Britain's coalition government so well not just because its meanings are all positive, but also because they are wide-ranging. To one lot of people, fairness means establishing the same rules for everybody, playing by them, and letting the best man win and the winner take all. To another, it means making sure that everybody gets equal shares. Those two meanings are not just different: they are opposite. They represent a choice that has to be made between freedom and equality. Yet so slippery--and thus convenient to politicians-- is the English language that a single word encompasses both, and in doing so loses any claim to meaning.

单选题 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.
