规则变化是指动词原形后加 -ed 形成过去式,如:
work - worked
watch - watched
talk - talked
不规则变化是指动词原形变化后形成过去式,如:
go - went
come - came
see - saw
缺省变化是指动词原形直接作为过去式,如:
put - put
cut - cut
hit - hit
这些规则来自英语的演变过程,在不同的历史时期,英语的语法和词汇都有所变化,导致了这些变化规则的产生。
例句:
I worked hard yesterday. (我昨天很努力工作。)
He went to the store. (他去商店了。)
She put the book on the table. (她把书放在桌子上。)
