1. 疑问词在句中不充当主语或者不修饰主语时,一般过去时的特殊疑问句结构为：疑问词 + 一般疑问句？例如：What did you do yesterday? 昨天你做什么了？When were you born? 你是什么时候出生的？Why didn’t you come here? 你们为什么没到这儿来？
2. 疑问词在句中充当主语或修饰主语时,一般过去时的特殊疑问句结构为:疑问词 + 行为动词的过去式(或 was/were + 表语) + 其它成分?例如:Who cleaned our classroom yesterday? 昨天谁打扫我们的教室了？Who was on duty the day before yesterday? 前天谁值日？Whose father came to see our teacher just now? 刚才谁的父亲来看我们老师了？好了，关于一般过去时，我们就先谈到这里。
