BThe electronic instrument is slightly more expensive.
CThe piano is slightly more expensive.
DThe piano is much more expensive.
正确答案： D解析：
事实细节的找寻和判断。题干中的关键词为price，从而定位到录音中的“One of the most important reasons for the great popularity of electronic instruments is, of course, their relatively low price.”，可知电子乐器之所以如此盛行，其中一个主要原因就是其价位相对低廉。由此可推测，与电子钢琴相比，传统钢琴要贵得多。因此选项D为正确答案。
【录音原文】
We are rapidly nearing the end of this course in history of classical music. We have covered several centuries in a very short time. Much too short to do the music justice, of course, but then this is a survey course. From now until the end of this term, we will be talking about and listening to electronic music. You probably already know that it was in the 1950s that musical computers and synthesizers first appeared in universities. The first commercial synthesizers were sold about this time, too. The sophistication and complexity of these instruments has now increased to the point that they can produce almost any kind of sound. Some alarmists believe these new instruments will bring an end to classical music or that they already have. You know I don’t share this view, though I agree we are in the midst of revolution in instrument design. This, however, is not the first such revolution in musical history and probably not the last one either. Remember we’ve already studied the similar case in the early 19th century when the piano replaced the harpsichord and modem brass and wind instruments came into being. One of the most important reasons for the great popularity of electronic instruments is, of course, their relatively low price. Well, just look at it, only about 400 dollars for a piano. Naturally this has done a lot to increase sales for electronic instruments, expecting them to completely replace acoustic instruments. -
第23题：
单选题According to the passage, the income gap between rich and poor could widen again as ______.Athe unemployment rate is lowered
Bthe increase of benefits is independent of price increase
Cthe income tax rate is increasing
Dthe increase of benefits is only based on prices
正确答案： A解析：
题目问的是：根据文章，富人和穷人间的收入差距可能会因为什么再次扩大？文章第2段提到“Some long-term sick...grow relatively poorer if... raise benefits only in line with prices.”，以及第5段提到“it could widen again if the real value of earnings accelerated away from the real value of prices-linked benefits”，表明了如果福利只与价格挂钩，不顾人们收入的真正价值，贫富差距很可能会拉大。故D正确。
