(a shame, no wonder, etc.) 3.It is suggested that Miss Liu (should) give a performance at the party.( decided, ordered, requested, proposed, etc)

I’d rather you had finished the work yesterday. 在would rather句型中，与过去事实相反，从句 的谓语动词用过去完成时；与现在、将来事实相 反，从句的谓语动词用过去时。
六 有时虚拟语气的条件从句不用if引导，而用but for, without, if only, otherwise等词。 1) But for your help, I couldn’t have made such great progress in English. 2) Without air, we couldn’t live. 以but for, without开头的句子，谓语动词的形式 和if的主句的一致。 3) If only the weather were fine. 以If only开头的句子，谓语动词的形式和if从句的 一致。 4) I had been there by taxi, otherwise I would have missed the train. 主、从句的谓语动词的形式都和if从句相一致。
