你有一个语法错误，检查这个：

   function updateScore()

                if (stopscore == false) then
                        score = score + 1
                        scoreText.text = "score: " .. score
                        scoreText:setReferencePoint(display.CenterLeftReferencePoint)
                        scoreText.x = 0
                        scoreText.y = 30
                else
                        if( contents < score and monster.isAlive == false) then  
                                file:write(score)   
                                file:close()
                                reader:close()                            
                        else
                                file:close()
                                reader:close()
                        end
                end     
     end
