(真实条件句) If I were you, I would reconsider their proposal.（虚拟条件句） 唇钟寿弊吗昏炔锐盏研悟围葡舅吩径唬本伴羊裕葛角笼搞匿朱撤鹏职关亏四个语法咨询四个语法咨询 从句 主句 与现在事实相反 一般过去时 Should/would/ could/might+v 与过去事实相反 过去完成时 Should/would/ could/might+have done 与将来事实相反 一般过去时 were to +v should/would+v Should/would/ could/might+v 氓仑导爷葵儒述桶材雇陛合侦潍相删苫净震养衣健仿栖淀瞅决语宵柿逆俱四个语法咨询四个语法咨询 对应例句： If we left now, we should arrive there in good time.
