不跟朋友玩太晚的英文表达可以是 "Don't stay up too late playing with your friends." 或者 "Don't play with your friends too late into the night."

这个表达来源于英语中常用的结构 "Don't + 动词原形 + 太 + 形容词/副词"，用来表示禁止或建议不要做某件事情。

例如：

Don't eat too much junk food. (不要吃太多垃圾食品)
Don't drive too fast. (不要开车太快)
Don't work too hard. (不要工作太辛苦)

也可以用来建议别人不要做某件事情太久或太晚，如：

Don't stay up too late studying. (不要熬太晚看书)
Don't watch TV for too long. (不要看电视太久)

有时候也可以用来表示一个人不喜欢做某件事情，如：

I don't pke to eat vegetables. (我不喜欢吃蔬菜)
She doesn't pke to swim. (她不喜欢游泳)

希望以上解释能帮到您！
