　　Section II Reading Comprehension Part A

　　第一篇：

　　Rats and other animals need to be highly at tuned to social from others so that can identify friends to cooperate with and enemies to avoid. To find out if this extends to non-living beings, Loleh Quinn at the University of California, San Diego, and her colleagues tested whether rats can detect social signals from robotic rats.

　　They housed eight adult rats with two types of robotic rat-one social and one asocial-for 5 our days. The robots rats were quite minimalist, resembling a chunkier version of a computer mouse with wheels-to move around and colorful markings.

　　During the experiment, the social robot rat followed the living rats around, played with the same toys, and opened caged doors to let trapped rats escape. Meanwhile, the asocial robot simply moved forwards and backwards and side to side.

　　Next, the researchers trapped the robots in cages and gave the rats the opportunity to release them by pressing a lever.

　　Across 18 trials each, the living rats were 52 percent more likely on average to set social robot free than the asocial one. This suggests that the rats perceived the social robot as a genuine social being. They may have bonded more with the social robot because it displayed behavious like communal exploring and playing. This could lead to the rats better remembering having freed it earlier, and wanting the robot to return the favour when they get trapped, says Quinn.

　　The readiness of the rats to befriend the social robot was surprising given its minimal design. The robot was the same size as a regular rat but resembled a simple plastic box on wheels. “We’d assumed we’d have to give it a moving head and tail, facial features, and put a scene on it to make it smell like a real rat, but that wasn’t necessary,” says Janet Wiles at the University of Queensland in Australia, who helped with the research.

　　The finding shows how sensitive rats are to social cues, even when they come from basic robots. Similarly, children tend to treat robots as if they are fellow beings, even when they display only simple social signals. “We humans seem to be fascinated by robots, and it turns out other animals are too,” says Wiles.

　　Why CEOs Actually Deserve Their Gazillion-Dollar Salaries

　　By Tyler Cowen

　　April 11, 2019

　　IDEAS

　　Cowen is Holbert L harris chair of economics at George Mason University and the author most recently of Big Business: A Love Letter to an American Anti-Hero.

　　It is fashionable today to bash Big Business. And there is one issue on which the many critics agree: CEO pay. We hear that CEOs are paid too much (or too much relative to workers), or that they rig others' pay, or that their pay is insufficiently related to positive outcomes. But the more likely truth is CEO pay is largely caused by intense competition.

　　It is true that CEO pay has gone up-top ones may make 300 times the pay of typical workers on average, and since the mid-1970s, CEO pay for large publicly traded American corporations has, by varying estimates, gone up by about 500%. The typical CEO of a top American corporation-from the 350 largest such companies--now makes about $18.9 million a year.

　　While individual cases of overpayment definitely exist, in general, the determinants of CEO pay are not so mysterious and not so mired in corruption.

　　In fact, overall CEO compensation for the top companies rises pretty much in lockstep with the value of those companies on the stock market.

　　The best model for understanding the growth of CEO pay, though, is that of limited CEO talent in a world where business opportunities for the top firms are growing rapidly. The efforts of America s highest-earning 1% have been one of the more dynamic elements of the global economy. It's not popular to say, but one reason their pay has gone up so much is that CEOs really have upped their game relative to many other workers in the U.S. economy.

　　Today's CEO, at least for major American firms, must have many more skills than simply being able to run the company CEOs must have a good sense of financial markets and maybe even how the company should trade in them. They also need better public relations skills than their predecessors, as the costs of even a minor slipup can be significant. then there s the fact that large American companies are much more globalized than ever before, with supply chains spread across a larger number of countries. To lead in that system requires know ledge that is fairly mind-boggling.

　　There is yet another trend: virtually all major American companies are becoming tech companies, one way or another. An agribusiness company, for instance, may focus on R&D in highly IT-intensive areas such as genome sequencing. Similarly, it is hard to do a good job running the Walt Disney Company just by picking good movie scripts and courting stars; you also need to build a firm capable of creating significant CGi products for animated movies at the highest levels of technical sophistication and with many frontier innovations along the way.

　　On top of all of this, major CEOs still have to do the job they have always done--which includes motivating employees, serving as an internal role model, helping to define and extend a corporate culture, understanding the internal accounting and presenting budgets and business plans to the board. Good CEOs are some of the world's most potent creators and have some of the very deepest skills of understanding.

　　26.【題干】which of the following has contributed to CEO pay rise? _____

　　【選項】

　　A.The growth in the number of cooperations

　　B.The general pay rise with a better economy
