play

1.说“玩某种游戏”用play，有时用play at，说“玩”（某物）用play with，如play (at) football，play (at) chess和play (at) cards，play with a ball和play with a doll。说“弹奏（某物）”不可没有with。

2.说“弹奏（乐器）”现在说play比说play on（或upon）普通，如play the violin现在比play on（或upon）the violin普通。

3.These boys play in the garden every morning等句子里的play作“游玩”解。这意思专用于儿童，不用于成人，如不可说These men play in the garden every morning，该把play改作enjoy themselves或have a good time。at play（正在游玩）也专用于儿童。例如：The boys are at play.
