old million-dollar buildings are constantly being torn down and replaced by new fifty-million-dollar ones.
in london, rome, paris, much of the land has only been built on once in all their long history.
in relatively new new york, some lots have already been built on four times.
= 다른 대도시들에 비해 뉴욕에서는 오래된건물들이 여러 번 바뀌고일부 구역이 이미 4번이나 지어졌다는 말인가여??
