答案 Technological Innovations In 1871, the first passenger elevators were used in office buildings/ and allowed architects to build higher than people could comfortably walk./ Another innovation was in building technique./ In 1885, the steel skeleton was introduced and allowed for the construction of tall buildings/ that could withstand high winds./ We take for granted some of the other inventions that enabled people to live and work in skyscrapers./ For example, few people realized that the telephone was necessary for vertical communication/ and that flush toilet and vacuum incinerator made waste disposal possible./ Now as we enter the age of super skyscraper,/ some with more than 200 floors,/ we see the need for even more technological innovations./ In the area of heating and cooling systems, for example,/ for all their benefits, these super tall buildings do cause problems though. For one thing they place enormous strain on parking and traffic in urban areas./ But let’s leave behind these technical concerns/ and move on to consider some of the design elements that have come to characterize the age of the skyscraper./
解析 这篇听写材料中的长单词相对较多，这就要求在听写的时候尽量的加快写字速度，如果一时没有跟上录音的速度，也可以先用缩写或者一定的符号代替，否则很难把整篇文章都写全。另外，文中的steel skeleton等词，刚开始可能不知道其含义，但是听到后面的withstand strong wind后，就可以知道这里是说结构坚固，再根据发音也就可以联想到是钢结构了。注意多次出现的skyscraper的拼写。
