were you 和did you 的用法

were 是句子的谓语,有“是”的意思,were you 后跟的是名词,形容词或动词的ing形式,表示你是……吗?比如,were you a teacher?（你是个老师吗?）； were you happy?（你是高兴的吗?） were you watching that game at that time?（你那会儿是正在看电视吗?） 其回答是,yes,i was、 no,i wasn't
did 是助动词,没意义.did you 后必须跟动词原形,表示你做什么了吗.比如,did you climb the mountain yesterday?（你昨天爬山了吗?）其回答是 yes,i did、 no,i didn't
