单选题The idea that some groups of people may be more intelligent than others is one of those hypotheses that dare not speak its name. But Gregory Cochran is 1 to say it anyway. He is that 2 bird, a scientist who works independently 3 any institution. He helped popularize the idea that some diseases not 4 thought to have a bacterial cause were actually infections, which aroused much controversy when it was first suggested. 5 he, however, might tremble at the 6 of what he is about to do. Together with another two scientists, he is publishing a paper which not only 7 that one group of humanity is more intelligent than the others, but explains the process that has brought this about. The group in 8 are a particular people originated from central Europe. The process is natural selection. This group generally do well in IQ test, 9 12-15 points above the 10 value of 100, and have contributed 11 to the intellectual and cultural life of the West, as the 12 of their elites, including several world renowned scientists, 13 .

The former has been 15 to social effects, such as a strong tradition of 16 education. The latter was seen as a (an) 17 of genetic isolation. Dr. Cochran suggests that the intelligence and diseases are intimately 18 . His argument is that the unusual history of these people has 19 them to unique evolutionary pressures that have resulted in this 20 state of affairs.

单选题{{B}}Passage One{{/B}} Much has been written about the potential for management to become isolated from customers and employees. This phenomenon often occurs not just within top management, but also within middle management. I've seen this isolation phenomenon in many companies. The symptoms are quite apparent: Managers spend a great deal of time talking to themselves and studying operating numbers. They spend precious little time with customers or with employees, trying to understand the system of the business. And when they do spend time with them, they often do not probe deeply into needs, concerns, and opportunities. This phenomenon, often referred to as being "internally focused", can be tremendously insidious (隐伏陷害的). Although the need for understanding and spending time with customers has been well documented, I find few managers spending time in the field. The benefits of doing so are clear. A visit with your counterparts at customers' distribution centers, for example, not only builds relation ships that can prove useful when problems arise, but also uncovers numerous opportunities to enhance(增进，提高) your performance and deepen your company's linkage with those customers. There are many ways to connect with and understand employee perspectives(观点，看法). Some companies have found formal sessions in which senior managers solicit (恳求，请求) ideas from employees to be very useful. These can be run either as focus groups or as structured discussions. Managers also should exploit every opportunity to gather organizational knowledge from employees. Some successful managers collect employees' opinions by what often is referred to as "managing by walking around" or the "10-minute cup of coffee". They, may, for example, go to employees' offices and solicit their opinions. Or at lunch or when they take a cup of coffee, they "mix with the troops" and solicit their input. Rather than talk about the latest game, you can solicit employees' ideas by asking questions like: What are you working on? How's it going? What's good about our organization? What could be better? How could we better serve our customers or improve our processes? What do you think we should be doing differently? You'll be surprised at how valuable a "10-minute cup of coffee" together with a brief conversation with an employee can be. It will make you a more effective manager.
