they have not a dreary commitment to mean ambitions or love comfort.
They are not anxious social climbers, and they have no devotion to
material things. 我们位年强人振奋。它们带有自由的气息，他们不会为狭隘的
野心和贪婪享受而孜孜以求。他们不是焦虑的向上爬的人，他们不会对物质性的东
西难舍难分。
97. I am always amazed when I hear people saying that sport creates
goodwill between the nations, and that if only the common peoples of the
world could meet one another at football or cricket, they would
have no
inclination to meet on the battlefield. 每次我听说体育运动能够在国家间建
立起友好感情，说世界各地的普通人只要能在足球场或板球场上相遇就会没有兴趣
在战场上相遇的话，我都倍感诧异。
98. It is impossible to say simply for the fun and exercise: as soon
as the question of prestige arises, as soon as you feel that you and
some larger unit will be disgraced if you lose, the most savage
combative instincts are around. 没有可能仅仅为了娱乐或锻炼而运动：一旦有
了问题，一旦你觉得你输了你和你所属团体会有失体面时，你最野蛮
的好斗本能就
会被激发出来。
99. It has been found that certain bats emit squeaks and by
receiving the echoes, they can locate and steer clear of obstacles-----
-or locate flying insects on which they feed. This echo-location in bats
is often compared with radar, the principle of which is similar. 人们已
经发现，某些蝙蝠发出尖叫声并靠接受回响来锁定和避免障碍物——或者找到它们
赖以为生的昆虫。蝙蝠这种回响定位法常拿来和原理与之很相近似的雷达相比。
100. As the time and cost of making a clip drop to a few days and a
few hundred dollars, engineers may soon be free to let their
imaginations soar without being penalized by expensive failure. 随着芯片
制造时间和费用降低到了几天和几百美元，工程师们可能很快可以任他们的想象驰
骋而不会被昂贵的失败所惩罚。
