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 ares 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 form 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 consumers what information they hold and how many money they make form it. Govemments could order the sharing of certain kinds of data, with users' consent.

Restarting antitrust for the information age will not be easy But if govemments don't wants a data oconomy by a few giants, they must act soon.

1.Why is there a call to break up giants?

A. They have controlled the data market

B. They collect enormous private data

C. They no longer provide free services

D. They dismissed some new-born giants

2.What does the technological innovation in Paragraph 3 indicate?

A. Data giants’ technology is very expensive

B. Google’s idea is popular among data firms

C. Data can strengthen giants’ controlling position

D. Data can be turned into new services or products

3.By paying attention to firms’ data assets, antitrust regulators could .

A. kill a new threat B. avoid the size trap

C. favour bigger firms D. charge higher prices

4.What is the purpose of loosening the giants’ control of data?

A. Big companies could relieve data security pressure.

B. Governments could relieve their financial pressure.

C. Consumers could better protect their privacy.

D. Small companies could get more opportunities.

Like many thickly populated urban neighborhoods, Lincoln Park also has rats. A lot of rats. “Every night when I walk down the sidewalk, I see rats, ” says 36-year-oId Kelly McGee, who has come to accept this aspect of city living. “It’s an urban area; I don't know what else we can expect.”

McGee lives just down the block from the old Children's Memorial Hospital, which is about to be torn down as part of a massive redevelopment project. “Construction all over the city often disturbs rats that are living underground,” says Lincoln Park’s City Council representative, Alderman Michele Smith. “Every developer has to do active rat reduction on site, ”Smith says. Already, there are poisonous and inviting food boxes all around the old hospital complex. But the developer of the hospital site still warned residents in a recent community meeting that when digging begins later this month, the rat problem could be awful.

Victoria Thomas, who lives a few miles north of Lincoln Park in Chicago’s Lake View neighborhood, says she tried everything from underground fencing to poison traps to wipe out rats, but nothing worked until she got some cats. From the first day she got the cats, Thomas says the rats started to disappear.

“The cats will kill off a great deal of the initial population of the rats, ”says Paul Nickerson, who manages the Cats at Work program for Tree House Humane Society. “And through spreading their pheromones, a chemical produced by an animal, the cats will keep other rats from filling their absence.” Nickerson says that is what makes the cat program so successful in keeping rats away for the long term. ” The rats are far from stupid. They smell the cats’ pheromones so they’ll stay out of the cats’ territory(领域).”

After Smith highlighted the program in a recent newsletter, Nickerson and Tree House Humane Society have been getting lots of calls from people seeking their own cat colonies. That means a lot more wild cats that might otherwise be killed out of pity will be cared for while doing something that they love: hunting rats.

1.What is McGee’s attitude towards the rat problem?

A. Indifferent. B. Tolerant.

C. Annoyed. D. Frightened.

2.What does the underlined word in the last but one paragraph refer to?

A. Rats’ stupidity.

B. Tree House Humane Society.

C. Cat’s nature of killing rats.

D. The smell of cat’s pheromones.

3.What does the last paragraph suggest?

A. The program is a win-win thing.

B. Cats should be taken good care of.

C. Wild cats are more skilled at hunting.

D. It’s important to keep the ecological balance.
