if開頭的用法

1.與現在事實相反
If+S+過去式動詞，S+would(could ,should, might)+原型動詞
例如:If I were rich,I would help you.
因為現在我不有錢，所以是與現在事實相反的用法

2.與過去事實相反
If+S+過去完成式，S+would(could ,should, might)+have+p.p
例如:If he had told me the truth,I would not have made the mistake.
因為已經是過去的事了，所以假設句一律用完成式

3.與未來事實相反
表示對未來事情的假設，實際上絕不可能發生。
If+S+were to +V，S+would(could, should, might)+原型動詞
例如:If we were to live to be 200 years old,we could change everything.

4.現在或未來可能發生的狀況
If+S+現在式動詞，S+ 祈使句 或 will(can,may,shall )+原型動詞
例如:If it rains tomorrow,I shall not go.
