depression. that was the finding of a study that builds on earlier study finding. they show that individuals who live or work in low levels of light overnight can develop clinical depression. doctors use the word “clinical depression” to describe severe form of depression. signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide. in the new study, american investigators designed an experiment that exposed hamsters(仓鼠) to different colors. the researchers chose hamsters because they are nocturnal, which they sleep during the day and are active at night.the animals were separated into four groups. one group of hamsters was kept in the dark during their night-time period. another group was placed in front of a blue light, a third group slept in front of a white light, while a fourth was put in front of a red light. after four weeks, the researchers noted how much sugary water the hamsters drank. they found that the most depressed animals drank the least amount of water. randy nelson heads the department of neuroscience at ohio state university. he says animals that slept in blue and white light appeared to be the most depressed. “what we saw is that these animals didnt show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim red light, they did not.” randy nelson notes that photosensitive cells in the eyes have little to do with eyesight. he says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle. he says theres a lot of blue in white light. this explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness. 8. researchers use hamsters in the experiment because _. a. they are similar to humans in dealing with colors b. they are easy to observe and study c. they are sensitive to colors like human beings d. they are active at night and sleep during the day. 9. what sign shows that the hamsters are being depressed?a. they drink less sugary water. b. they dont sleep well c.

late at night to avoid being depressed?a. not being exposed to dim red light when using computers b. equipping their computer screens to put it more in the reddish light c. living or working in low levels of light overnight. d. going to see doctors of clinical depression regularly for help dtraditionally, it has been the workers role to work and managements role to manage. managers have planned and directed the firms operations with little thought of consulting the labor force. managers have rarely felt forced to obtain the workers opinions or to explain their decisions to their employee. at most, companies have provided “suggestion boxes” in which workers could place ideas for improving procedures. in recent years, however, many management specialists have been arguing that workers are more than sellers of labor- they have a vital stake (利害关系) in the company and may be able to make significant contributions to its management. furthermore, major company decisions affect workers and their dependants. this is particularly true of plant closings, which may put thousands on the unemployment lines. should workers, then, play a stronger role in management?workers should have a role in management. at the very least, the labor force should be informed of major policy decisions. a common complaint among ordinary workers is the lack of information about company policies and actions. between 1980 and 1985 about five million workers were the victims of plant closings and permanent lay-offs(失业)，often with no warning. at least 90 days notice ought to be given in such circumstances so that workers have time to adjust. management should consult workers before closing a plant, because the workrs might be able to suggest ways of improving productivity and reducing costs and might be willing to make concessions (妥协) that will help keep the plant operating. it should become a general practice to include workers in some managerial decision making. there ought to be representatives of the workers on the firms board of directors or others major policy-making groups. if ordinary workers are given a voice in the planning and management of the work flow, they will help to make improvements, their spirits will rise and their productivity will increase. as a further incentive(激励)，they must be given a share in the companys profits. this can be done through employee stock ownership plans (员工持股计划)，bonuses, or rewards for efficiency and productivity. finally, when a plant can no longer operate at a profit, the workers should be given the opportunity to purchase the plant and run it themselves. 12. what can we learn about managers from paragraph 1?a. they were not quite qualified. b. they disliked “suggestion boxes”. c. they never consulted the labor force. d. they seldom obtained workers opinions13. in recent years, many management specialists have been arguing that workers _. a. are not sellers of the precuts any longer b. should have a say in management of the company c. are less affected by company decisions than before d. are able to make the final decisions for the company 14. according to the passage, what happened between 1980 and 1985?a. workers did not make necessary concessions b. many companies were closed because of strikes. c. managers consulted workers before closing a plant. d. about 5 million workers were laid off without advance notice. 15. if they are not given a voice in managerial decision making, workers_.a. cannot get a share in the companys profitsb. will not have the opportunity to purchase the plant c. may lack the incentive to increase their productivity d. can still get bonuses for efficiency and productivity 参考答案15 bacdb 61
