He is the man.
He came here last week.
He is the man who came here last week. (该句中的“who came here last week”为定语从句,修饰“the man”,很明显,从句中的“who”是“came back”动作的发出者,所以“who”在从句中充当主语。)
She is the woman.
I served her yesterday.
She is the woman I served yesterday. (该句中的“I served yesterday”为定语从句,修饰“the woman”,其实,定语从句中省掉了关系代词“who,whom或that”。关系代词在定语从句中作宾语时,可将其省略。完整的句子应为“She is the woman who / whom / that I served yesterday. ”如果将从句部分的关系代词代入句中的话,应为:I served who / whom / that yesterday,很明显,从句中的“who / whom / that”是“served”动作的承受者,所以关系代词在从句中充当宾语。)
They are the books.
I bought the books last year.
They are the books I bought last year. (该句和第二句用法相同,关系代词which / that因在定语从句中充当宾语,被省略了,能看明白吧?其实完整的句子应该是:They are the books which / that I bought last year. 关系代词代入定语从句中,则为:I bought which / that last year. 能看出“which / that”充当的是宾语吧。)
