2)人称代词有主格和宾格之分.通常主格作主语,宾格作宾语.如:

注意 英语习惯上的用法.当两个以上的人称代词作主语时,其并列时其排列顺序一般为you, he, she, I,而复数时为we, you, they:如男女并列时,应先男后女,如:He and she...如果在表示不好意思,承担责任时,单数时用,I, he, she, you,复数时用They, you, we,如:Tom and I are good friends.
3)人称代词还可作表语.作表语时用宾格.如:
-Who is knocking at the door?-It's(我) me.
4)人称代词在than之后与其他人或事物进行比较时,用主格和宾格都可以.如:
He is older than(我)me/I.

指示代词包括:this, that, these, those.

2)有时that 和those 指前面讲到过的事物,this和these则是指下面将要讲到的事物.如:

3)有时为了避免重复提到的名词,常可用that或those代替.如:
