反身代词
表示「……自己」，也用于一批固定搭配。
myself / yourself / himself；by oneself / teach oneself
要点
- 反身代词要与主语在人称和数上一致。
- 常作宾语或同位语，不能单独作主语。
- 固定搭配：by oneself、enjoy oneself、teach oneself、help oneself。
- myself / yourself / himself / herself / itself / ourselves / yourselves / themselves。
- 只有第二人称靠单复数分两种：yourself（你一个）／yourselves（你们）。
- 作同位语时表强调「本人」，位置可前可后：The president himself opened the meeting.
- 后接反身代词的一批动词要成套记：hurt oneself、introduce oneself、buy oneself sth、forget oneself、kill oneself。
- by oneself 有两层意思：「独自」和「靠自己」，替成 alone 只留下第一层。
例句
Let me introduce myself.
让我自我介绍一下。
He learned to play guitar by himself.
他自学弹吉他。
They are old enough to take care of themselves.
他们够大了可以照顾自己。

易错提示
- 反身代词不能单独作主语 —— 不说 Myself did it.
- by oneself 有两个意思：「独自」和「靠自己」，看句子判断。
- 主语是 we / you / they 时反身代词要跟着一块变复数：You should believe in yourselves.（不能写 yourself）
- enjoy oneself 的 oneself 必须与主语一致 —— 别不分主语一律写 myself。
