A new commodity brings about a highly profitable, fast-growing industry, urging antitrust(反垄断) regulators to step in to check those who control its flow. A century ago, the resource in question was oil. Now similar concerns are being raised by the giants(巨头) that deal in data, the oil of the digital age. The most valuable firms are Google, Amazon, Facebook and Microsoft. All look unstoppable.
Such situations have led to calls for the tech giants to be broken up. But size alone is not a crime. The giants’ success has benefited consumers. Few want to live without search engines or a quick delivery. Far from charging consumers high prices, many of these services are free (users pay, in effect, by handing over yet more data). And the appearance of new-born giants suggests that newcomers can make waves, too.
But there is cause for concern. The internet has made data abundant, all-present and far more valuable, changing the nature of data and competition. Google initially used the data collected from users to target advertising better. But recently it has discovered that data can be turned into new services: translation and visual recognition, to be sold to other companies. Internet companies’ control of data gives them enormous power. So they have a "God’s eye view" of activities in their own markets and beyond.
This nature of data makes the antitrust measures of the past less useful. Breaking up firms like Google into five small ones would not stop remaking themselves: in time, one of them would become great again. A rethink is required — and as a new approach starts to become apparent, two ideas stand out.
The first is that antitrust authorities need to move from the industrial age into the 21st century. When considering a merger(兼并), for example, they have traditionally used size to determine when to step in. They now need to take into account the extent of firms’ data assets(资产) when assessing the impact of deals. The purchase price could also be a signal that an established company is buying a new-born threat. When this takes place, especially when a new-born company has no revenue to speak of, the regulators should raise red flags.
The second principle is to loosen the control that providers of on-line services have over data and give more to those who supply them. Companies could be forced to reveal to consumers what information they hold and how much money they make from it. Governments could order the sharing of certain kinds of data, with users’ consent.
Restarting antitrust for the information age will not be easy. But if governments don’t want a data economy controlled by a few giants, they must act soon.

If you want to disturb the car industry, you'd better have a few billion dollars: Mom-and-pop carmakers are unlikely to beat the biggest car companies. But in agriculture, small farmers can get the best of the major players. By connecting directly with customers, and by responding quickly to changes in the markets as well as in the ecosystems(生态系统）, small farmers can keep one step ahead of the big guys. As the co-founder of the National Young Farmers Coalition (NYFC, 美国青年农会）and a family farmer myself. I have a front-row seat to the innovations among small farmers that are transforming the industry.
For example, take the Quick Cut Greens Harvester, a tool developed just a couple of years ago by a young farmer, Jonathan Dysinger, in Tennessee, with a small loan from a local Slow Money group. It enables small-scale farmers to harvest 175 pounds of green vegetables per hour—a huge improvement over harvesting just a few dozen pounds by hand—suddenly making it possible for the little guys to compete with large farms of California. Before the tool came out, small farmers couldn't touch the price per pound offered by California farms. But now, with the combination of a better price point and a generally fresher product, they can stay in business.
The sustainable success of small farmers, though, won't happen without fundamental changes to the industry. One crucial factor is secure access to land. Competition from investors. developers, and established large farmers makes owning one's own land unattainable for many new farmers.
From 2004 to 2013, agricultural land values doubled, and they continue to rise in many regions.
Another challenge for more than a million of the most qualified farm workers and managers is a non-existent path to citizenship — the greatest barrier to building a farm of their own. With farmers over the age of 65 outnumbering(多于）farmers younger than 35 by six to one, and with two-thirds of the nation's farmland in need of a new farmer, we must clear the path for talented people willing to grow the nation's food.
There are solutions that could light a path toward a more sustainable and fair farm economy, but farmers can't clumsily put them together before us. We at the NYFC need broad support as we urge Congress to increase farmland conservation, as we push for immigration reform, and as we seek policies that will ensure the success of a diverse and ambitious next generation of farms from all backgrounds. With a new farm bill to be debated in Congress, consumers must take a stand with young farmers.

In the 1760s, Mathurin Roze opened a series of shops that boasted(享有）a special meat soup called consomme. Although the main attraction was the soup, Roze's chain shops also set a new standard for dining out, which helped to establish Roze as the inventor of the modern restaurant.
Today, scholars have generated large amounts of instructive research about restaurants. Take visual hints that influence what we eat: diners served themselves about 20 percent more pasta(意大利面食）when their plates matched their food. When a dark-colored cake was served on a black plate rather than a white one, customers recognized it as sweeter and more tasty.
Lighting matters, too. When Berlin restaurant customers ate in darkness, they couldn't tell how much they'd had: those given extra-large shares ate more than everyone else, but were none the wiser—they didn’t feel fuller, and they were just as ready for dessert.
Time is money, but that principle means different things for different types of restaurants. Unlike fast-food places. fine dining shops prefer customers to stay longer and spend. One way to encourage customers to stay and order that extra round: put on some Mozart(莫扎特）.When classical, rather than pop, music was playing, diners spent more. Fast music hurried diners out.
Particular scents also have an effect: diners who got the scent of lavender(薰衣草）stayed longer and spent more than those who smelled lemon, or no scent.
Meanwhile, things that you might expect to discourage spending—"bad" tables, crowding. high prices — don't necessarily. Diners at bad tables — next to the kitchen door, say — spent nearly as much as others but soon fled. It can be concluded that restaurant keepers need not "be overly concerned about ‘bad' tables," given that they're profitable. As for crowds, a Hong Kong study found that they increased a restaurant's reputation, suggesting great food at fair prices. And doubling a buffet's price led customers to say that its pizza was 11 percent tastier.

A.not aware of eating more than usual
B.not willing to share food with others
C.not conscious of the food quality
D.not fond of the food provided
2.How could a fine dining shop make more profit?
A.playing classical music.
B.Introducing lemon scent.
C.Making the light brighter,
D.Using plates of larger size.
3.What does the last paragraph talk about?
A.Tips to attract more customers.
B.Problems restaurants are faced with.
C.Ways to improve restaurants' reputation.
D.Common misunderstandings about restaurants.
Preparing Cities for Robot Cars
The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn’t leading the way here. Companies have been testing their vehicles in cities across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.
While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.
Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services.
A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.
Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you’ll have no trouble answering these questions.
Most of us observed much more as children than we do as adults. A child’s day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的）to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.
The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they’d felt cold water at first.
Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.
The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what’s around them. I asked them what they’d seen. "Oh, a few birds," they said. They seemed bent on their destinations.
Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.z.

Fire Prevention Information
The University of Adelaide employs a full-time staff of fire prevention professionals. They inspect all campus buildings and test and maintain all sprinkler(喷水灭火装置）systems fire alarms and fire extinguishers (灭火器). They also provide educational programs or fire safety in the residence hall. Whenever you move to a new area, you should locate the fire alarm pull stations and the two exits nearest your room.
Fire Alarms
The floors of all campus buildings are equipped with manual(手动的）fire alarm systems which include fire alarm pull stations and pipes. Most are also equipped with automatic fire alarm systems consisting of heat detectors, smoke detectors and sprinklers. For your safety, never tamper with(胡乱摆弄）these systems. False fire alarms are illegal and may lead to imprisonment.
Fire Drills
A fire drill will be conducted in your residence hall every semester. During a fire drill, please do the following:
·Take your room key and ID, close and lock the door to your room.
