In 1871 the first passenger elevators were used in office buildings and allowed architects to build higher than people could comfortably walk. Another improvement 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 (a machine designed to burn things in order to destroy them) made waste disposal possible. Now as we entered the age of super skyscraper, some with more than 200 floors, we see the need for even more technological improvements. 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 row 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.
选项
A、Projected changes in the building code.
B、Design features of modem skyscrapers.
C、Strategies for reducing traffic jamming.
D、Methods of estimating construction costs.
答案
B
解析
推理题。在听录音之前就可以排除C,因为从其他选项可以判断本文很可能和traffic jamming无关。问题中的关键词是discuss next,听的过程中只要留意到文中 move on to...the design elements就可以判断选项B为正确答案。如果没留意到这一完整的细节,也可以用排除法。文章没有提到关于changes,traffic jamming和costs的细节,却提到design,因此选B。
