47、. Therefore C. Furthermore D. However（分数：2.50）A.B.C.D. 解析：解析 考查逻辑关系。上一句指出成年人一般每个晚上需要七至九小时的睡眠才能感到精力非常充沛并以最佳状态正常工作，下一句则指出美国人的睡眠时间比过去少了。由此可知，表示转折的However“然而，但是”符合上下文的逻辑关系，是正确答案。Otherwise“否则”表示条件，Therefore“因此”表示结果，Furthermore“而且”表示递进，都不符合题目的要求。(2).A. averaged B. attained C. allocated D. alleged（分数：2.50）
48、A. B.C.D.解析：解析 考查动词辨析。从语意分析，allocate“分配，分派”和 allege“断言，宣称”与宾语的搭配都不合理。由于本句涉及的是一项调查结果，average“平均有”一词把美国人的平均睡眠时间清楚地表达了出来，故正确答案为 Aaveraged。而 attain“达到，获得”的意思显然与文意不符。(3).A. in B. since C. over D. before（分数：2.50）A.B. C.D.解析：解析 考查上下文语义。本段第二句已指出，美国人现在的睡眠时间比过去少。本句具体说明与不同时代相比大约减少了多少时间，因此正确答案只能是 since，表示从 19世纪
49、以来，而不可能是 in或before。也不可能是 over“在期间”。(4).A. Subsequently B. Incidentally C. Unfortunately D. Eventually（分数：2.50）A.B.C. D.解析：解析 考查副词辨析。下句指出，我们并没有很好地了解缺乏失眠的影响，与上一段最后一句表达的意思之间有一定的转折作用。Unfortunately“遗憾的是，可惜的是”反映了作者对美国人缺乏睡眠而又不了解由此带来的后果而感到遗憾，是正确答案。Subsequently“结果”和 Eventually“最终”都表示结果，不符合上下文的逻辑关系；Incidentally“顺便提一下”隐含补充说明的意思，也不符合文意。(5).A. adverse B. neutral C. potential D. reverse（分数：2.50）A. B.C.D.解析：解析 考查形容词辨析。从本段第四句的相关内容 their cognitive ab
