        Sporting activities are essentially modified forms of hunting

        behavior. Viewing biologically, the modern footballer is revealed as a S1.________

        formative period of hunting for food, they became farmers. Their

        improved intelligence, so vital to their old hunting life, were put to a new S9._______

        use-that of penning ( 把……关在圈中), controlling and domesticating

        their prey. The food was there on the farms, awaiting their needs. The

        risks and uncertainties of farming were no longer essential for survival. S10._______
