(2)人称代词作表语时，用宾格时较多，特别是在口语中，例如：

Who is knocking at the door?- It’s me. 谁敲门?-是我。

If I were her, I would take the advice. 我要是她就接收这个意见。

Imagine yourself to be me. 设想你是我。

但在下面这种结构中却常用主格：

It was he who did it.

It is she who wants it.

在表示比较的非正式的文体中，常用宾格代替主格：

He is more intelligent than her.

He is taller than I am.

3、在使用人称代词时还应注意以下几点：

(1)we, you两词有时可用来泛指一般人：

We (you) have to be cautious under such circumstances.

在这样的情况下大家应特别小心。

We (You) should keep calm even when we (you) are in danger.

即使在危急时刻也要保持冷静。

They也可用来泛指某一些人：

They don’t allow us to smoke here. 这儿不让抽烟。(They代表谁不清楚)

They don’t make decent furniture nowadays. 现今做不出象样的家具。

(2)she可以用来代表国家、船只、大地、月亮等：

I think England will do what she promised to do. 我想英国会履行她的诺言。

The “Easter” is due in tomorrow, isn’t she? 东方号轮船明天进港，是吗?
