61.下文中的their journey对做出正确选择作了提示，说明他们在旅途中。答案为A。
62. break中断。根据上文中的stopped可确定答案。当那些卡车司机和商贩在旅途中停下来进行短暂的休息时，他们喝点咖啡，吃点cheeseburger(放有干酪的肉饼)。答案为C。
63.这个句子的谓语动词用了现在完成时，since从此以后，常与完成时连用。从此以后他再也没关过门；ever曾经，常用于肯定句中，否定句是：He has never closed the door；later后来，常与一般过去时连用。答案为B。
64. mobile houses是一种用汽车装载的活动住房。for“为了”。a car park for mobile house为装载着活动住房的汽车提供的停车场。答案为D。
65.a 24-hour working trend二十四小时工作的趋向。下文的内容告诉我们，二十四小时工作已成为全球的趋向。而且，根据DC Hilton工作的性质，容易排除B、C和D项。touring business旅游事业；banking service银行服务业；delivering system邮递系统。答案为A。 
66.上文说明24小时工作成为一种趋向，很多行业开始整夜开放。A项performing“表演”；B项pretending“假装”；D项hesitating“犹豫”，均不合题意。答案为C。
67.根据下一段的内容可判断出is this really a good thing?是对二十四小时工作提出的质疑，所以两句之间是转折关系，要用But填写。Furthermore“另外”。答案为C。 
68.be growing concern about对……关心不断增加。人们越来越多地对不睡觉对社会所造成的长远危险予以关注。B项understanding“理解”；C项interest“兴趣”；D项sense“意识”。答案为A。
69.several几个。意思是：最严重的人为灾难发生在黎明前。而few和none都表示否定，all表示全体，都与短文内容不符。答案为B。 
70.stay awake保持清醒的状态。preserve“保护，维护”，后常接名词；become表示由不清醒向清醒变化的过程；maintain作系动词的意思是“维持”。答案为D。
