請問英文不規則動詞是否有一個變化規律!!!

There is no exact rule for it.

But, in fact, your observation is right.

A majority of such similar words can be written in present tense
,past tense and present perfect based on their suffixes like ' -eak'.

For the minor ones, they do not follow the 'rule'.

Cf. ' leave' 'left' ' left'

' interweave' 'interwove' 'interwoven'.


Hope you find it useful.
