33、sors they are presented, and (c) some form of physical and/or psychological responses will occur. Therefore, internal characteristics may determine physical and emotional responses exhibited by individuals as a result of stressors. There are two distinct types of stressors, those without and within.

34、 Without stressors originate outside individuals and include such things as environmental or work-related demands. Within stressors are those from within individuals. These stressors tend to include individuals personal values, attitudes, and self-concepts. There are three major types of stressors:

35、environmental, organizational, and individual. Stressors are found to emerge from the environment and individuals. Internal characteristics would be stressors from within individuals. Internal characteristics are identified in numerous documents and cited as major sources of individual stress. Resea

36、rchers have found that internal characteristics could contribute to individuals susceptibility m stress and that these factors may even dictate how individuals handle the stress that they encounter; they state that internal characteristics actually contribute to the amount of stress individuals are

37、able to tolerate. A large number of the negative experiences of beginning vocational individuals emerge from internal characteristics. The role-related stress is a function of the individuals personality and job preparation. Perceived professional competence has been found to be a source of stress f

38、or many individuals. Individuals have been known to experience stress because of their lack of occupational confidence in a particular work or particular environment. Rapid changes in the world and technologies have caused individuals to feel incompetent and experience stress due to their inability

39、to always remain current and up-to-date in their areas of expertise. Job satisfaction and individual stress are found to be strongly correlated. The amount of stress and degree of job satisfaction experienced by individuals directly influence the quality of individual work life. A list of events rev

40、ealed recently is closely related to individuals life satisfaction that could affect their stress and performance at work. These events included marriage, divorce, pregnancy, death of a loved one, and change of residence. 70 According to the author of this passage, the term “stress“ can be defined a

41、s （ A） an individuals response to an external action. （ B） a process of ones adaptation to the situation. （ C） a demand an external situation places on a person. （ D） physical and psychological demands on a person. 71 Which of the following is NOT included as the three concepts involved in the study

42、 of stress? （ A） Situational demands. （ B） Different ways of reaction and adaptation. （ C） Forms of ones different responses. （ D） Individuals tendency lo the stressors. 72 Which is NOT the stressor found to emerge from within the individual himself? （ A） Organizational stresses. （ B） Personal value

43、s. （ C） Personal attitudes. （ D） Self-concepts. 73 Which of the following is NOT to be a source of stress, according to the author of this passage? （ A） Rapid changes in the world and technologies. （ B） Perceived professional competence. （ C） Work-related environments. （ D） Rash personality characte

44、ristics. 73 The History of the Atomic Bomb On August 2, 1939, just before the beginning of World War , Albert Einstein wrote to then President Franklin D. Roosevelt. Einstein and several other scientists told Roosevelt of efforts in Nazi Germany to purify uranium-235, which could be used to build an

45、 atomic bomb. It was shortly thereafter that the United States Government began the serious undertaking known then only as “The Manhattan Project.“ Simply put, the Manhattan Project was committed to expediting research that would produce a viable atomic bomb. The most complicated issue to be address

46、ed in making of an atomic bomb was the production of ample amounts of “enriched“ uranium to sustain a chain reaction. At the time, uranium-235 was very hard to extract. In fact, the ratio of conversion from uranium ore to uranium metal is 500:1. Compounding this, the one part of uranium that is fina

47、lly refined from the ore is over 99% uranium-238, which is practically useless for an atomic bomb. To make the task even more difficult, the useful U-235 and nearly useless U-238 are isotopes (同位素 ), nearly identical in their chemical makeup. No ordinary chemical extraction method could separate the

48、m; only mechanical methods could work. A massive enrichment laboratory/plant was constructed at Oak Ridge, Tennessee. Harold C. Urey and his colleagues at Columbia University devised an extraction system that worked on the principle of gaseous diffusion, and Ernest O. Lawrence (inventor of the Cyclo

49、tron) at the University of California in Berkeley implemented a process involving magnetic separation of the two isotopes. Next, a gas centrifuge was used to further separate the lighter U-235 from the heavier, non fissionable U-238. Once all of these procedures had been completed, all that needed to be done was to put to the test the entire concept behind atomic fission (“splitting the atom,“ in laymans terms).
