“他自己玩得不开心”常见的英文表述有：He didn't have a good time by him lf. 或者 He wasn't happy playing by him lf.
“have a good time”是一个常用的短语，表示“玩得开心，过得愉快”，其否定形式“didn't have a good time”则表示“玩得不开心”；“by one lf”表示“独自，自己”，所以“by him lf”就是“他自己”。
“happy”是“开心的，快乐的”，“be happy doing sth.”表示“做某事很开心”，“wasn't happy playing”即“玩得不开心”。 这两种表述都能够准确传达“他自己玩得不开心”的意思。
