沪教七下第四单元语法专练 反身代词与方位介词 第一部分:反身代词 一、知识点梳理 1. 反身代词的形式 反身代词表示"自己",必须与主语的人称和数保持一致。 人称 单数 复数 第一人称 myself (我自己) ourselves (我们自己) 第二人称 yourself (你自己) yourselves (你们自己) 第三人称 himself (他自己) themselves (他们自己) herself (她自己) itself (它自己) 记忆口诀: 一、二人称用物主(my myself, your yourself/yourselves) 第三人称用宾格(him himself, them themselves) 单数self,复数selves 2. 反身代词的三大用法 用法 说明 例句 强调用法 强调主语或宾语"亲自"、"本人",可去掉而不影响句子完整 I myself finished the work.(我亲自完成) 宾语用法 作宾语,表示动作回到主语自身 Be careful! Don't hurt yourself. 固定搭配 与特定动词连用,构成固定短语 enjoy oneself(玩得开心) 3. 常考固定搭配 enjoy oneself = have a good time(玩得开心) They enjoyed themselves at the party. by oneself = alone(独自) She did her homework by herself. help oneself to(随便吃/用) Help yourself to some fish. look after oneself / take care of oneself(照顾自己) You're old enough to look after yourself. teach oneself = learn by oneself(自学) He taught himself English. 4. 易错点提醒 不要混淆:itself(它自己) vs it's self(错误写法) yourself(你一个人) vs yourselves(你们一群人) 主语和宾语是同一个人时,宾语必须用反身代词 误:I saw me in the mirror. 正:I saw myself in the mirror. 二、反身代词专项练习题 (一)用适当的反身代词填空 1.
