谢邀。 根据 主谓一致 的原则，i was是英语中的主流。。 但是在if引导的 虚拟语气 中，如果与现在相反，谓语动词用过去式，be动词一律为were. If i were you.（虚拟语气中be动词只能用were）（或者也可将were放句首倒装为were i you，意义不变） 以下是其他一些关于虚拟语气的语法点： （图片来源于本人可亲可敬的英语老师往届学生的笔记） Is there any rules for i was/were?
Los Angeles crime scenes in 1953
If i were a bird, i would fly in the sky.
所以传到现代英语中，i am和he/she/it is的虚拟式的标准用法就应该是 if i/he/she/it were，而不是was。 由上面两表也可以看出，古英语中的虚拟式（虚拟语气）是非常规范、常用的，每个动词都有规范的.
Who were these buildings designed by? From other's conversation,i found out they mentioned i was and sometimes they also mentioned i were. Or who was these buildings designed by? 在表达“i was”或“i were”时，应该使用“i was”。 “was”的用法：在英语中，“was”是动词“be”的过去式，主要用于第一人称单数和第二人称单数以及第三人称单数主语。当描述真实发生的过.
Does were/was refer to these buildings or who? 第二个if i were you 和第三个if he be found guilty 有什么区别呢。 Which of the following is correct ?
