老俞課堂：2009年英語(yǔ)六級(jí)考試經(jīng)典100句

　　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. 沒(méi)有可能僅僅為了娛樂(lè)或鍛煉而運(yùn)動(dòng)：一旦有了問(wèn)題，一旦你覺(jué)得你輸了你和你所屬團(tuán)體會(huì)有失體面時(shí)，你最野蠻的好斗本能就會(huì)被激發(fā)出來(lái)。

　　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. 人們已經(jīng)發(fā)現(xiàn)，某些蝙蝠發(fā)出尖叫聲并靠接受回響來(lái)鎖定和避免障礙物——或者找到它們賴(lài)以為生的昆蟲(chóng)。蝙蝠這種回響定位法常拿來(lái)和原理與之很相近似的雷達(dá)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. 隨著芯片制造時(shí)間和費(fèi)用降低到了幾天和幾百美元，工程師們可能很快可以任他們的想象馳騁而不會(huì)被昂貴的失敗所懲罰。
