without虚拟语气用法「without虚拟语气用法和if」
otherwise,but for without 虚拟语气里怎么用 结构是什么
otherwise,but for without 虚拟语气条件不是通过if引导的条件句来表示,而是暗含在上下文中,但都可以还原成if引导的,用法与if条件虚拟一样
(1)用but for 、without(如果没有)等来代替条件从句,如

Without electricity human life would be quite different=If there were no electricity ,human life would be quite different
(2) 用otherwise、or(or else),even though等表示与上文的情况相反,从而引出虚拟语气。如:
I lost your address.Otherwise,I would have visited you long before. =I lost your address.If I hadn't lost your address ,I would have visited you long before.
but for (要不是) , but that (要不是) , without, otherwise , or (否则) 虚拟语气是什么用法?
虚拟语气的虚拟时态原则在哪类句子中都是一致的,即:
对现在的情况虚拟,时态倒退成一般过去时;
对将来的情况虚拟,时态倒退成一般过去时;
对过去的情况虚拟,时态倒退成过去完成时。
因此,出现but for、without时,先从句子中判断出是在对哪种情况虚拟。
应用条件
在表示假想的虚假的、与事实相反的或难以实现的情况时用虚拟语气,表示主观愿望或某种强烈情感时,也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法,愿望,假想,猜测,怀疑或建议,而不是根据客观实际,就用虚拟语气。主要是英语语法的一种表达。
