如:I am a student. Tom is a boy, and he is a student.
Mary is very pretty, and she likes singing.
The boys are students, and they are in the room.
The dog is small. It is Tom's.
2) 人称代词的句法功能
A) 人称代词有主格和宾语之分:主格用作主语,宾格用作宾语。
B) 人称代词的主格形式在在句中作主语和表语。
如: I like music(主语). She is a teacher.(主语)
She and I are good friends(主语).
Neither she nor I am student.
