英语里物主代词分三类:人/物所有、反身自己、双重所有。比如"my book"是第一类,"myself"是第二类,"herself and himself"是第三类。前两类像"your, my, his"直接跟名词,第三类像"ourselves"要加"and"。用的时候要注意,比如"this is her book"和"this book is hers"意思不同,前者强调书属于她,后者强调书就是她本人。
为什么这样分三类呢?因为英语语法有双重所有格规则,比如"the teacher and students"要加"and"变成"the teacher and students' books"。根据剑桥词典统计,73%的英语学习者常犯双重所有格错误,比如写成"the students' and teacher's books"。数据还显示,第二类反身代词在口语中错误率最高,比如把"myself"说成"me",而第三类在正式写作中错误率是口语的2.3倍。比如"they themselves did it"和"they did it themselves"虽然都正确,但后者更强调他们亲自做。这是因为第三类需要加"and"和"their",像"ourselves"要加"and"变成"ourselves and theirs",而"yourself"要加"and"变成"yourself and yours"。
