The British RAF base where I was stationed as part of a contingent of USAF personnel had one narrow road winding through the crowded residential area. After a rash of minor vehicle pedestrian accidents，the USAF commander decided to reduce the speed limit to three m.p.h.
    Shortly after the new limit was posted，an MP sergeant issued a speeding citation to a jeep driver for going five m.p.h. I was curious to know how the MP had determined the jeep's speed so exactly. “I was jogging to get to the PX before it closed，” he explained，“and as I passed the jeep，I noticed that the speedometer read five m.p.h.”
    速度限制
    我作為美國空軍人員分遣部隊的一員駐扎在英國皇家空軍某某地，那里有一條狹窄的馬路蜿蜒穿過擁擠的居民區(qū)。 因為多次出現(xiàn)汽車撞傷行人一類不甚嚴重的車禍，美國空軍司令員決定將車速限制在每小時三英里。
    新的車速限制公布后不久，一名騎警中士因一名吉普車司機開車時速達五英里而給他開了一張超速傳票。
    我很想知道騎警是怎樣如此精確地知道那輛吉普車的速度的。“我遛達著要在郵局關(guān)門之前到達那里，”他解釋道：“當我超過吉普車時，我注意到計速器指向了每小時五英里?！?BR>
