exact text as granted — not AI-modified
1 . A golf club head, comprising:
 a club head body, said club head body comprising a recessed portion thereof, a plurality of supporting ribs and a plurality of internal grooves alternatively arranged in said recessed portion; and   a ball-striking face plate fixedly mounted in said recessed portion of said club head body, said ball-striking face plate comprising a back wall supported on said supporting ribs of said club head body, a front face opposing said back wall and adapted for striking a golf ball and a plurality of external score lines arranged on said front face.   
     
     
         2 . The golf club head as claimed in  claim 1 , wherein said external score lines are respectively suspending above said internal grooves between each two adjacent supporting ribs so that the part of said ball-striking face plate that is supported on said supporting ribs is not deformable, and the other part of said ball-striking face plate that is not supported on said supporting ribs is deformable. 
     
     
         3 . The golf club head as claimed in  claim 1 , wherein said internal grooves extend in a transverse direction. 
     
     
         4 . The golf club head as claimed in  claim 3 , wherein said internal grooves are spaced from one another at an equal distance. 
     
     
         5 . The golf club head as claimed in  claim 3 , wherein said internal grooves are spaced from one another at different distances. 
     
     
         6 . The golf club head as claimed in  claim 3 , wherein said external score lines extend in a transverse direction. 
     
     
         7 . The golf club head as claimed in  claim 6 , wherein said internal grooves are spaced from one another at an equal distance. 
     
     
         8 . The golf club head as claimed in  claim 6 , wherein said internal grooves are spaced from one another at different distances. 
     
     
         9 . The golf club head as claimed in  claim 3 , wherein said external score lines extend in a predetermined direction deviated from a transverse direction at a predetermined angle. 
     
     
         10 . The golf club head as claimed in  claim 9 , wherein said internal grooves are spaced from one another at an equal distance. 
     
     
         11 . The golf club head as claimed in  claim 9 , wherein said internal grooves are spaced from one another at different distances. 
     
     
         12 . The golf club head as claimed in  claim 1 , wherein said internal grooves extend in a predetermined direction deviated from a transverse direction at a predetermined angle. 
     
     
         13 . The golf club head as claimed in  claim 12 , wherein said internal grooves are spaced from one another at an equal distance. 
     
     
         14 . The golf club head as claimed in  claim 12 , wherein said internal grooves are spaced from one another at different distances. 
     
     
         15 . The golf club head as claimed in  claim 12 , wherein said external score lines extend in a transverse direction.
