句型1：If ＋主语＋过去时，主语＋ should (could, would, 或might) ＋动词原形

句型2 : If ＋主语＋had＋过去分词，主语＋ should（could, would, 或might）＋ have ＋过去分词

句型3：If ＋主语＋过去时/ should ＋动词原形/ were to＋动词原形，主语＋ should (could, would, 或might) ＋动词原形

句型4：主语＋（should）＋动词原形

句型5：wish后的宾语从句

与现在愿望不一致：主语＋过去时；

与过去愿望不一致：主语＋ had ＋过去分词/ could ＋ have＋过去分词；

与未来愿望不一致：主语＋ would / could ＋动词原形。如：

句型6： It’s time句型（当It’s time后用that从句时应该为“主语＋ should ＋动词原形”或“主语＋过去时”）

It’s time that you went / should go to school.

句型7：If only引起的感叹句相当于“How I wish ＋宾语从句”

句型8：would rather, as if（though）引导的句子也需使用虚拟，表示过去的情况用过去完成时，表示现在与将来的情况用过去时。

句型9：without, but, but for, but that, otherwise引起的短语或句子常暗含着虚拟条件。

句型10：If it were not for ... / If it hadn’t been for ... (要不是因为……)，其后面的主句也需使用虚拟。
