English Grammar Help

I 是應該加was(如果是過去式的話.)
I am-現在式
I have been -present perfect tense(忘了中文)
I was(過去式)

所以答案是2.)和4.)

i were you 通常用於假設的句子上.
eg, if i were you, i would not help him.
在假設句子上,用i was you 反而不及I were 正式

如果不是假設的句子,用I were XX大多數會被人當是錯

你好，依你的问题看，我们是应该答 2) 或 4) 的。

因为 I 是 First Pronoun，所以要用 was 的，而不是用 were 的。

我们通常在想象某样事物/状况 (imagine something / a situation) 时，英国人是用 I were 的，反而美国人会比较喜欢用 I was 的，请看以下的例子。。。

1) If I were you, I would not buy the car.

2) If I were you,I definitely wouldn't do that.

3) If I were rich, I would have a yacht.

希望能帮到你咯。。。: )

I think 2,4正確,冇點解.
