反身代词表示"自己"，由"物主代词/人称代词宾格 + self/selves"构成。口诀：一二人称物主加，三人称用宾格加。
顺口溜记忆
- 反身代词表自己，主宾表同别忘记
- 第一第二用物主，my、your 加 self/selves
- 第三用宾格，him、her、it、them 加 self/selves
- 单数 self 复数 selves，s 结尾的变 selves
要点讲解
- 构成：myself, yourself, himself, herself, itself, ourselves, yourselves, themselves
- 作宾语表示动作回到主语：I taught myself English. 我自学英语。
- 作同位语加强语气：I did it myself. 我自己做的。
- 常用短语：enjoy oneself(玩得开心), help oneself to(随便吃), by oneself(独自), look after oneself(照顾自己)
例句解析

- Help yourself to some fish. 请随便吃些鱼。
- He did his homework by himself. 他独自完成了作业。

易错提醒
- by oneself 表示"独自、单独"；oneself 必须和主语保持一致，如 She enjoyed herself. 不能说 herself 与主语不一致。
