题目内容

[A] Defining genius.
[B] Bias attacked.
[C] Truly great mind is born, not made.
[D] The line between the exceptional and the ordinary blurs.
[E] Brain steers, labor facilitates.
[F] Great lesson from a great character.
The greatest results in life are usually attained by simple means, and the exercise of ordinary qualities. The common life of every day, with its cares, necessities, and duties, afford ample opportunity for acquiring experience of the best kind; and its most beaten paths provide the true worker with abundant scope for effort and room for self-improvement. The road of human welfare lies along the old highway of steadfast well-doing; and they who are the most persistent, and work in the truest spirit, will usually be the most successful.
1. ______
Fortune has often been blamed for her blindness; but fortune is not so blind as men are. Those who look into practical life will find that fortune is usually on the side of the industrious, as the winds and waves are on the side of the best navigators. In the pursuit of even the highest branches of human inquiry, the commoner qualities are found the most useful--such as common sense, attention, application, and perseverance.
2. ______
Genius may not be necessary, though even genius of the highest sort does not disdain the use of these ordinary qualities; the very greatest men have been among the least believers in the power of genius, and as worldly wise and persevering as successful men of the commoner sort. Some have even defined genius to be only common sense intensified. A distinguished teacher and president of a college spoken of it as the power of making efforts. John Foster held it to be the power of lighting one's own fire. Buffon said of genius "it is patience".
3. ______
Newton's was unquestionably a mind of the very highest order, and yet, when asked by what means he had worked out his extraordinary discoveries, he modestly answered, "By always thinking unto them." At another time he thus expressed his method of study: "I keep the subject continually before me, and wait till the first dawnings open slowly by little and little into a full and clear light." It was in Newton's case, as in every other, only by diligent application and perseverance that his great reputation was achieved. Even his recreation consisted in change of study, laying down one subject to take up another. To Dr. Bentley, he said: "If I have done the public any service, it is due to nothing but industry and patient thought."
4. ______
The extraordinary results effected by dint of sheer industry and perseverance, have led many distinguished men to doubt whether the gift of genius be so exceptional an endowment as it is usually supposed to be. Thus Voltaire held that it is only a very slight line of separation that divides the man of genius from the man of ordinary mould. Beccaria was even of opinion that all men might be poets and orators, and Reynolds that they might be painters and sculptors. If this were really so, that stolid Englishman might not have been so very far wrong after all, who, on Canova's death, inquired of his brother whether it was "his intention to carry on the business!"
5. ______
Locked, Helvetius, and Diderot believed that all men have an equal aptitude for genius. But while admitting to the fullest extent the wonderful achievements of labor, and recognizing the fact that men of the most distinguished genius have invariably been found the most indefatigable workers, it must nevertheless be sufficiently obvious that, without the original endowment of heart and brain, no amount of labor, however well applied, could have produced a Shakespeare, a Newton, a Beethoven, or a Michelangelo.

阅读以下关于网络地址转换(NAT)的技术说明,结合网络拓扑图回答问题1至问题3。
【说明】
网络地址转换(NAT)技术可用来缓解IP地址短缺问题和实现TCP负载均衡功能。动态地址翻译技术在子网外部使用少量的全局地址,通过路由器进行内部和外部地址的转换。其好处是节约全局的公网IP地址,而且不需要改变子网内部的任何配置,只需在边界路由器中设置一个动态地址变换表就可以工作。
而IP伪装技术是NAT的另一种实现技术,它通过使用边界路由器的IP地址可以把子网中所有主机的IP地址隐藏起来,因此它既可以作为一种安全手段使用,借以限制外部对内部主机的访问;还可以用来实现虚拟主机和虚拟路由,以便达到负载均衡和提高可靠性的目的。
在图5-18所示的网络设计方案中,在边界路由器Router上进行了TCP负载均衡技术的配置,其部分网络地址映射NAT表如表5-9所示。
在路由器上采用了NAT技术,请用300字以内的文字简要说明NAT技术中的动态地址翻译和IP地址伪装各有什么技术特点?

江苏华西100万吨炼铁炼钢工程40t转炉工程2004年12月份发现转炉基础内侧混凝土裸露部分因长期受出钢、出渣、高温热辐射影响致使转炉基础内侧混凝土大面积剥落,受损高度2m,深度为30~50mm,因此已严重的影响了正常的生产,由于炼钢工程施工单位已交付生产厂家生产,分析原因是由于设计问题及业主生产操作中的原因造成的。经会同业主、设计院协商后,采取了加固措施,达到了安全使用目的。转炉基础加固费用15万元。
