if条件句分两种: 真实条件句和虚拟条件句, 如 何区分则看假设的条件是否能实现。
非真实条件句表示的假设只是说话人的主观愿 望或假想,是不可能实现的或实现的可能性不 大, 此时要用虚拟语气。
虚拟语气可以表示过去,现在和将来的情况,它的 基本特点是从句中谓语动词的时态“退后一步” 。 ◆与现在事实相反的假设
此时从句通常用过去时, 主句用should / would / could / might + 动词原形。 If they were here, they would help you.
此时从句通常用过去完成时,主句用should / would / could / might + have + 动词的过去分词。 If you had come here yesterday, you would have seen him. 如果你昨天来这里的话, 你就会见到他。
◆与将来事实可能相反的假设 此时从句通常用过去时/ were to +动词原形/ should + 动词原形,主句用should / would / could / might + 动词 原形。 If you succeeded, everything would be all right.
If you were to succeed, everything would be all right.
If you should succeed, everything would be all right.
注意: 在虚拟语气的从句中, be动词的过去式一律 用were, 不用was。 If I were you, I would go to ask him.
would / should / 动词过去式(be用 were) might / could + 动 should + 动词原形 词原形 were to + 动词原形 would / should / 动词过去式(be 用 were) might / could + 动 词原形
would / should / might / could have + 动词过去分词
