　　（2015·湖南）An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.

　　This of course created a new problem：dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice：either change the first floors of their buildings into basements，and the second stories into main floors，or hoist the entire buildings to meet the new street level. Small wood－frame buildings could be lifted fairly easily. But what about large，heavy structures like Tremont Hotel，which was a six－story brick building?

　　That's where George Pullman came in. He had developed some house－moving skills successfully. To lift a big structure like the Tremont Hotel，Pullman would place thousands of jackscrews(螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10 jackscrews. At Pullman's signal each man turned his jackscrew the same amount at the same time，thereby raising the building slowly and evenly. Astonishingly，the Tremont Hotel stayed open during the entire operation，and many of its guests didn't even notice anything was happening.
