I + were还是was?

I + were还是was? 是 i was 还是 i were yes,i were 还是 was.为什么 yes,i were 还是 was.为什么 虚拟语气中,应该用I was还是I were you （was,were） I (was,were) he (was,were) If I were you.这个句型对么.是were还是was或是am yes,i were or was They____fantastic.填were还是was? 第三人称用was还是were? 是if i was you 还是 if i were you?那是所有虚拟语气 am 都变成 were 么? 英语语法是If I was a boy还是If I were a boy? Were you watching TV when I called you还是when i was calling you?为什么? She began to feel as though she were(was) flying是用was正确还是were正确?这句是虚拟语气吗?因为我知道一个句型if I were you,I will play basketball.就把 was 改成 were了. I was a boy还是I were a boy?为什么if I were you,而不是if I was you?was[wCz; wEz]be 的过去式(第一人称及第三人称单数)if she were you,... I thought you__having a break 填was 还是were 为什么you是第二人称怎么这里也用were If he [] ready,I would go.是只能用were,还是were和was都可以,简单解释下. 英语小语法,很容易的!为什么 总是听到有的人说 I was.有的人又说：I were...那到底是 用was 还是用were呢?
