填空题 Pyramid City is an even more ambitious project to solve Tokyo"s housing
problem. A 1,000 - metre tall Pyramid, 12 times higher than the Great
Pyramid of Giza in Egypt, would contain 55 smaller pyramids, each of them 21
would be the size of the Giza original. If it is built, the pyramid will
cosist in a series of skyscrapers suspended from the inside of the structure, 22
the pyramid will be 80 storey high, with parkland in-between the skyscrapers. 23
Three quarters of a million of people will live there. The skyscraper will 24
be linked by series of hollow tubes containing a high-speed transport system. 25
Parts of the construction, include more than 150 kilometers of tunnels, will be 26

built by spider robots, and power will be provided by waves and wind.
A major problem is that Japan is situating on the seismic "ring of fire"— 27
an area of volcano activity where stretches around the Pacific Ocean. 28
Pyramid City will have to withstand earthquakes, tsunamis and underwater 29
volcanic eruptions.
The designers of Pyramid City are certain that it will be built and make 30
safe from earthquakes, but probably not for another 100 years.
