2001年6月大学英语四级考试 试题答案与详解 31. By the time he arrives in Beijing, we ____ here for two days. A) have been staying B) have stayed C) shall stay D) will have stayed D)。【译文】等他到北京的时候，我们已经在这里呆两天了。 【解析】将来完成时题。By (the time) 后接一个表示将来时间的词或短语（如the year of 2005，the next month等）或是一个表示将来动作的从句（如本题）时，主句要有将来完成时，表示将来某一时间之前完成的动作。选项A）和C）没有用完成时，不表示动作已经完成；选项B）没有用将来时态，不表示将来的动作。 32. According to the American federal government, residents of Hawaii have the longest life ____: 77.2 years. A) scope B) rank C) span D) scale C)。【译文】据美国联邦政府资料，夏威夷的居民寿命最长：77.2岁。 【解析】单词辨义题。Life span为固定搭配，意为“寿命”；scope表示“（活动、影响、书等涉及的）范围”；rank“级别”；scale“规模，比例”。 33. The millions of calculations involved, had they been done by hand, ____ all practical value by the time they were finished. A) had lost B) would lose C) would have lost D) should have lost C)。【译文】数以百万计的计算如果是人工完成的话，到计算完成时早已失去其实际价值了。 【解析】虚拟语气题。Had they been done by hand是一个因省略了if而倒装的虚拟条件句，该从句用的是过去完成时，表示与过去情况相反的假设，所以主句也应表示与过去情况相反的事实，用would + have + 过去分词的形式，故C）为答案。 34. As a public relations officer, he is said ____ some very influential people. A) to have been knowing B) to be knowing C) to have known D) to know D)。【译文】作为一名公关官员，据说他认识一些很有影响力的人。 【解析】惯用法题。Sb. Is said to do sth. 相当于It is said that sb. Does sth.，表示众人的观点，意思是“据说…”，本句相当于It is said that he knows some very influential people. Know是一个瞬间动词，不用于进行时，故排除A)和B)；不定式的完成式表示其动作发生在谓语动作之前，to have bought表示“已经买了”，本句中know的动作和say是同时发生的，故用to + 动词原形，不用不定式的完成式。 35. Our hopes ____ and fell in the same instant. A) aroused B) arose C) raised D) rose D)。【译文】我们的希望在同一时刻升起又跌落。 【解析】动词辨析题。Rise是不及物动词，意思是“升起”，本句中的fell是fall（降落）的过去式，所以选择其反义词rose（rise的过去式）表意思上的对比。Arouse意思是“引起”，及物动词；arose的原形为arise，意思是“出现，引起”，不及物动词；raise“提高，抬起”，及物动词。 36. With the development in science and technology man can make various flowers ____ before their time. A) be bloomed B) blooming C) bloom D) bloomed C)。【译文】随着科技的发展，人类能使各种各样的花提前开放。 【解析】动词用法题。Make sb.
