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、The skyscraper’s effect on urban areas.
B、Safety regulations for skyscraper design.
C、The development of the modern skyscraper.
D、Problems with future skyscraper construction.
答案
C
解析
主旨题。在听录音之前预览所有选项,可以判断本文可能与skyscraper 的 construction 或 design有关。再分析本题的选项,四个选项分别涉及skyscraper的development,effect,problems和safety regulations四个方面,因此本题最有可能考查文章的主旨。问题中的mainly discuss是主旨题的关键词语之一。听录音的过程中只要抓住In 1871,In 1885和Now这三个表示时间的词,就可以判断本文是和skyscraper的development有关,因此答案选C。
