mar·ket·place /ˈmɑrkətˌples/
  商業中心;市場
  marketplace
       n 1: the world of commercial activity where goods and services
            are bought and sold; "without competition there would be
            no market"; "they were driven from the marketplace"
            [syn: market]
       2: an area in a town where a public mercantile establishment is
          set up [syn: mart]
  Market-place
     any place of public resort, and hence a public place or broad
     street (Matt. 11:16; 20:3), as well as a forum or market-place
     proper, where goods were exposed for sale, and where public
     assemblies and trials were held (Acts 16:19; 17:17). This word
     occurs in the Old Testament only in Ezek. 27:13.
       In early times markets were held at the gates of cities, where
     commodities were exposed for sale (2 Kings 7:18). In large towns
     the sale of particular articles seems to have been confined to
     certain streets, as we may infer from such expressions as "the
     bakers' street" (Jer. 37:21), and from the circumstance that in
     the time of Josephus the valley between Mounts Zion and Moriah
     was called the Tyropoeon or the "valley of the cheesemakers."
