If I were you, I would not accept his offer.
If I had time, I would certainly go to the cinema with you.
2) 表示与过去情况相反：主句谓语用“would / could / might + have +过去分词”，从句谓语用过去完成时。
If I had got up a little earlier, I wouldn’t have missed the train. If I had been more careful, I might have passed that exam.
3) 表示与将来情况相反：主句谓语用“would / could / might +动词原形”，从句谓语用“were +动词不定式”或“should +动词原形”。
