___if I had arrived yesterday without letting you know beforehand?
这个不是虚拟.也不是和过去相反.说的是"如果我昨天你不知道我到来你会惊讶吗"仔细观察整句没有和过去相反"只是单独讲述这件事希望帮到你.
if you had asked him beforehand
虚拟语气情境下与现在事实相反的用法是 从句:动词的过去式（be的过去式一般用were） 主句:would/ should/ could/ might + 动词原形 所以答案应为：you (should know) 或者 you (would know) 另外提供另外两种虚拟语气不同情境的用法： 与过去事实相反 : 从句 :had + 过去分词 主句 :would/ should/ could/ might + have + 过去分词 与将来事实相反 : 从句:动词过去式,should + 动词原形, 主句 :were to + 动词原形 would/ should/ could/

beforehand和before hand区别
beforehand和beforehand区别是：1、beforehand是副词,而before-hand是动词。2、beforehand的作用是放在副词后修饰动词,而before-hand是放在句子中,两个单词之间还有一段话。
在口语中，表示提前做什么，用in advance还是beforehand？我觉得in advance比较正式
