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。 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. ”/ "It's him"/ "it's her" “谁在敲门?”“是我。” 在很正式的英语中也用主格,可以说:It is I. 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。 为了避免太正式或太随便,我们可以用别的句式来表达。例: I was the one / person who broke the window. 3.人称代词处在动词之前,会影响选用主格还是用宾格。例如 but和except 既可作介词也可作连词,因此在but或except之后,用主格还是用宾格就要慎重。例: No one but / except I read the book. No one read the book but / except me / I. (me 比I 更常见)只有我读过这本书。 代词宾格的习惯用法——一道高考题的启示 (1)—Susan,go and join your sister cleaning the yard. —Why ____ ?John is sitting there doing nothing.
