一般过去时加ed

Question

一般过去时加ed有一道题 Tom always has a shower in the morning
要求陈述（昨天\上周等）发生的事情
他的答案是：this morning he had a shower
我不是很明白、哪个大神可以知道一下 谢谢🙏

Answer 1

this morning he had a shower里面用的过去时属于不规则变化的动词过去式：
have---had are---were get---got say---said feel---felt do/does---did is---was go---went
drink--drank eat--ate bring----brought think----thought buy----bought catch---- caught teach ---- taught sit----sat wear----wore cut----cut sweep----swept sleep——slept see----saw become----became[1] read——read等等
一般过去时加ed：
1．直接加ed：work—— worked look——looked
2．以不发音e结尾的单词，直接加d：live ——lived hope——hoped use——used
3．以辅音字母+y结尾的，变y为i加ed：study—— studied carry——carried worry——worried
4．以重读闭音节结尾且末尾只有一个辅音字母的，双写最后的辅音字母+ed：stop—— stopped plan——planned
重读闭音节体现形式为辅-元-辅结构，例如nod,n为辅音，o为元音，d为辅音。
5. 以ic结尾的动词，要把ic变成ick再加ed，如picnic→picnicked，traffic→trafficked
