1.人称代词的主格作主语,宾格作动词的宾语和介词的宾语。
例:They have English lessons on Saturday.他们星期六上英语课。The teacher asked them to stay in the classroom.老师叫他们呆在教室里。them就是宾格We are listening to them.我们在听他们说话。
2.人称代词作表语时,一般用宾格,特别是在日常会话中。例:"Who is knocking at the door?""It's me."I"It's him"/"it's her""谁在敲门?”“是我。”只有一个词的句子用宾格:"Who wants to try?""Me."“谁想试一试?”“我。”在“it + be +代词+定语从句"结构中,用宾格是随便的说法,用主格是非常正式的说法。例:It was me/ I who broke the window.是我打破了玻璃窗。
