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、It created design problems for architects.
B、It made skyscrapers more expensive to build.
C、It was needed for transporting construction materials.
D、It enabled architects to design their office buildings.
答案
D
解析
细节题。本题的四个选项中均是It作主语,在听问题的时候要注意It指代的是the invention of the elevator。文章第一句话说的就是elevator,关键信息是“...allowed architects to build higher...”,选项C符合原文。即使没有注意到这一信息,还可以根据文章中出现的improvement(s),inventions等词判断文章的主要基调是积极的,四个选项中只有D与之相符。
