Sports and games make our bodies
strong, prevent us from getting too fat, and keep us healthy. But these are not
their only use. They give us valuable practice in making eyes, brain and muscles
work together. In tennis, our eyes see the ball coming, judge its speed and
direction and pass this information on to the brain~ The brain then has to
decide what to do, and to send its orders to the muscles of the arms, legs, and
so on, so that the ball is met and hit back where it ought to go. All this must
happen with very great speed, and only those who have had a lot of practice at
tennis can carry out this {{U}}complicated chain of events{{/U}} successfully. For
those who work with their brains most of the day, the practice of such skills is
especially useful. Sports and games are also very useful for {{U}}character-training{ A. live a better life when they grow up B. know better how to behave properly in their future life C. understand better the virtues they learn in books D. all of the above [单选题] 人工智能的出现对马克思主义哲学意识论的意义是( ) 。
