　　“It is difficult for people to achieve professional success without sacrificing important aspects of a fulfilling personal life.”
　　In conclusion, given the growing demands of career on today’s professionals, a fulfilling personal life remains possible by working smarter, by setting priorities, and by making suitable career choices.
　　重申立场+总结理由
　　“Since science and technology are becoming more and more essential to modern society, schools should devote more time to teaching science and technology and less to teaching the arts and humanities.”
　　In conclusion, schools should not devote less time to the arts and humanities. These areas of study augment and enhance learning in mathematics and science, as well as helping to preserve the richness of our entire human legacy while inspiring us to further it. Moreover, disciplines within the humanities provide methods and contexts for evaluating the morality of our technology and for determining its proper direction.

　　“Job security and salary should be based on employee performance, not on years of service. Rewarding employees primarily for years of service discourages people from maintaining consistently high levels of productivity.”
　　In the final analysis, the statement correctly identifies job performance as the single best criterion for salary and job security. However, the statement goes too far, it ignores the fact that a cost-of-living salary increase for tenured employees not only enhances loyalty and, in the end, productivity, but also is required by fairness.

　　How far should a supervisor go in criticizing the performance of a subordinate? Some highly successful managers have been known to rely on verbal abuse and intimidation. Do you think that this is an effective means of communicating expectations? If not, what alternative should a manager use in dealing with someone whose work is less than satisfactory?
　　In conclusion, supervisors should avoid using verbal abuse and threats. These methods degrade subordinates, and they are unlikely to produce the best results in the long run. It is more respectful, and probably more effective overall, to handle cases of substandard work performance with clear, honest and supportive feedback.
