| 第2题：Ethiopians appear to have evolved a unique way of coping with thin mountain air.But how they do it remains a mystery. One way for the body to get enough oxygen to its tissues when breathing oxygen-poor air is for it to make more red blood cells. This increases the amount of hemoglobin(血红蛋白), the protein that carries oxygen.Although less haemoglobin in the arteries is saturated with oxygen at high altitudes, having more of it makes up for the shortfall. People native to the highAndes are known to have more red blood cells than lowlanders, and athletes who train at altitude can increase their concentration of cells. But while many Tibetans also live at high altitudes, they do not have significantly elevated levels of haemoglobin. Instead they seem to boost the amount of nitric oxide, which dilates(使膨胀) blood vessels and increases blood flow. NowCynthiaBeall, an anthropologist fromCase Western Reserve University inCleveland, Ohio, has found a third kind of adaptation. When she tested the blood of 236 people in theAmbaras region in the Semien Mountains ofEthiopia, she found that 95 percent of the haemoglobin in their arteries is saturated with oxygen, almost as much as that of people living at low altitudes and roughly 5 per cent above that of residents in theAndes or Tibet. "That shouldn’t be, "saysBeall. They must have a massively efficient way to get oxygen from the lungs to the blood, she says.But just what remains mysterious. They do not have higher concentrations of haemoglobin than anyone else, nor do they have a different kind of haemoglobin. Beall adds that this ability might be found in all people living in that part of the world, and not just those in the study. It might be why so many world-class endurance athletes areEthiopian. "The next study needs to look at that,"she says. According toCynthiaBeall, the haemoglobin in the arteries of theEthiopians ______.A．is saturated with more oxygen than lowlanders B．is saturated with as much oxygen as the Tibetans C．is more efficient than residents in theAndes and Tibet D．runs faster than people in any other region of the world |

| 第4题：Through the years, our view of what leadership is and who can exercise it has changed considerably. Leadership competencies have remained constant, but our understanding of what it is, how it works, and the ways in which people learn to apply it has shifteD、We do have the beginnings of a general theory of leadership, from history and social research and above all from the thoughts of reflective practitioners such as Moses, JuliusCaesar, and James Madison, and in our own time from such disparate sources of wisdom as Gandhi, WinstonChurchill, Mao Tse-tung, and Henry Kissinger, who have very little in common except that they have not only been there but tried with some fairness to speculate on paper about it. But tales and reflective observation are not enough except to convince us that leaders are physically strong and abnormally hard workers. Today we are a little closer to understanding how and who people lead, but it wasn’t easy getting there.Decades of academic analysis have given us more than 350 definitions of leadership. Literally thousands of empirical investigations of leaders have been conducted in the last seventy-five years alone, but no clear understanding exists as to what distinguishes leaders from non-leaders, and perhaps more important, what distinguishes effective leaders from ineffective leaders and effective organizations from ineffective organizations. Never have so many labored so long to say so little. Multiple interpretations of leadership exist, each providing a fragment of insight but each remaining an incomplete and wholly inadequate explanation. Most of these definitions don’t agree with each other, and many of them would seem quite remote to the leaders whose skills are being examineD、Definitions reflect fashions, political tides and academic trends. They don’t always reflect reality and sometimes they just represent nonsense. It’s as if whatBraque once said about art is also true of leadership: "The only thing that matters in art is the part that cannot be explaineD、" Many theories of leadership have come and gone. Some looked at the leader. Some looked at the situation. None has stood the test of time. With such a track record, it is understandable why leadership research and theory have been so frustrating as to deserve the label "the LaBrea Tar Pits" of organizational inquiry. Located in LosAngeles, these asphalt pits house the remains of a long sequence of prehistoric animals that came to investigate but never left the areA、 This passage is mainly concerned with ______. A、the inconsistent theories of leadership B、the famous leaders and their theories C、the changes in the trend of leadership D、the inaccurate definitions of leadership |
