I helped my mother cook a dinner.
My father whshed the clothes and I watched TV.不是说过去时,前面的动词变为过去式,后面的动词就为原型吗,为什么这里的watch要加ed?
请详细解释
类型不是和前一个一样吗，为什么用法不一样？

想必是LZ听课听漏了
过去式时前面的助动词变为过去式后面的动词为原型
附：助动词：do(did)
那是help的词组固定用法
help sb do（原型）sth
固定搭配不为句子的时态变动而变动
因此叫“固定”搭配

是不是说以后除了这些，其他动词都要变过去式

第一句句子中help sb. do是固定搭配
第二句句子中有两个主语，当中有一个and把整句句子分成两句小句。
而且并不是说有一个动词变形了，后面的动词就不变了。
例：I saw and heard the thing yesterday.
