Reflexive pronouns
反身代词是英语中表达“······自己；本身”含义的一类代词。有人称和数之分。它由第一人称、第二人称形容词性物主代词和第三人称人称代词宾格形式在词尾加-self 或-selves 构成。具体见下表：
人称 单数 复数
第一人称 myself ourselves
第二人称 yourself yourselves
第三人称 himself herself itself themselves
Grammar
用法：
反身代词与它所指的名词或代词形成互指关系，
在人称或数上保持一致。
（1）作宾语（作及物动词或介词的宾语）
表示动作的执行者和承受者是同一个人或事物。
e.g. I cut myself when I was cutting up vegetables.
我在切菜时切到我自己了。
The old man lives by himself in the countryside.
这位老人独自生活在乡下。
用法：
（2）作同位语（作主语或宾语的同位语，加强语气, 表示
“亲自；本身；本人”）
① 作主语的同位语 (反身代词一般紧跟主语之后/放在句末)
e.g. I myself do not agree. 我本人不同意。
He will speak to her himself. 他要亲自去跟她说。
② 作宾语的同位语 (此时反身代词一般紧跟宾语之后)
e.g. Would you please give this basketball toTom himself？

注意：反身代词不能单独作句子的主语。
