【正确答案】 D

【答案解析】解析：本题考查句子结构。空格所在句子是一个倒装结构，其正常语序应是the long—distance western routes…ridership had been declining…were______major concerns to Amtrak and its advertising agency DDB Needham。将选项代入，只有of最为符合句意，表示“在……之中"，即“在主要的担忧之中”，为正确选项。

【正确答案】 B

【答案解析】解析：本题考查定语从句关系副词。空格前的意思是，长距离的西部路线；空格后的意思是，乘客数量持续下降。可以判断出，前者应是后者事件发生地点，说明空格处的词引导的是定语从句，其先行词表示地点，所以，引导这个从句的应该是关系副词where，B选项为正确答案。

【正确答案】 A

【答案解析】解析：本题考查上下文语义。空格处之前信息为：Trains were fast，very luxurious，and quite convenient；之后信息为：other forms of transportation existing at the time。这里能看出有一个比较关系的存在，特别是本段首句已经说明火车是唯一可以穿越西部的方式，强调了其先进性。因此，此处compared最符合题意，为正确答案。

【正确答案】 C

【答案解析】解析：本题考查动词辨析。set表示“设定”；claimed表示“宣称”；established表示“建立；确立”；regarded表示“看做、认为”。在文中，空格句与其前一句为并列关系，意思是：汽车成为美国最为便捷的交通工具，而飞机则一跃成为长距离旅行最快捷的方式。文中描述的是汽车和飞机自然而然的发展变化，不带主观色彩，显然只有C选项最符合文意。

【正确答案】 C

【答案解析】解析：本题考查逻辑关系。在第一遍快速阅读时，我们可以了解到文章主要想要表达的是火车乘客数量显著下滑，并针对这一问题研究挽救方法。而在本题空格前，文章提到了，汽车和飞机成了方便快捷的交通工具，空格后出现单词task，显然是说，因此为了改善火车乘客下降情况，必须要让消费者认知火车的其他好处以增加客流，因此，C选项最为合理。

【正确答案】 B

【答案解析】解析：本题考查上下文语义。空格处表达的意思是，DDB Needham的任务就是要让消费者认识到坐火车旅行的其他优势。encourage是“鼓励”；induce表示“劝导、诱导”；stimulate表示“刺激”；discourage表示“劝阻、阻止”。将四个选项代入，显然B选项最切合文意，为正确答案。

【正确答案】 C

【答案解析】解析：本题考查上下文语义。空格处句意是：活动……乘坐火车获得的旅行体验，并将西部的火车之旅描绘成了美妙的探险。四个选项，involved表示“涉及；包含”；indicated表示“表明；显示”；stressed表示“强调”；overlooked表示“忽视；忽略”，再结合前文，意在向乘客展现火车的优势，因此。此处选项应为C选项，表达“活动强调了乘坐火车的旅行体验”，与文章重点保持一致。

【正确答案】 C

【答案解析】解析：本题考查上下文语义。空格处句意是：这些广告战略性地被放在以……为收视主导的电视节目中播放，通过展示美国风光来最有效地挖掘目标观众。旅行的本质即是休闲娱乐的，因此判定此类节目应是在以家庭为收视主导的电视频道上播放的。故C项为正确答案。
