动词过去式不规则变化:有那些单词是除双写改为单写加t的?“双写改为单写加t”这句话成立吗?

“动词原形中的ell改为old,变成过去式。如: sell—sold,tell—told ”那么这句话成立吗?
动词过去式不规则变化的理论是什么?规律是什么?
求助,回答得好加悬赏!

动词变为过去式依旧是动词,当然还会有动词的特性。(1)一般情况下,动词词尾加 ed ,如:   work—worked; play—played;want— wanted; act—acted   
(2)以不发音的 e 结尾动词,动词词尾加 d,如:   live—lived; move—moved; decide—decided; decline—declined; hope—hoped;   
(3)以
+ y结尾的动词,把y变为i 再加ed,如:   studied tried copied justified cried carried embodied emptied   
(4)以一个
结尾的
动词,双写词尾
,再加 ed,如:   stopped begged fretted dragged dropped planned dotted dripped   
(5)注:
的过去式变化规律性不强,须多加记忆。   go - went,make - made,get - got ,buy - bought ,come - came ,fly-flew ,is/am-was,are-were ,
,bring-brought,do-did,teach-taught, think-thought, say-said,sit-sat. read-read, spend-spent, eat-ate,give-gave,tell-told,write-wrote,feel-felt,find-found,hear-heard,know-knew,   put-put,grow-grew,take-took,catch-caught,come-came,become-became,swim-swam,sweep—swept,sing—sang,draw—drew,   
以上的(1)至(4)条中的发音均有改变,具体分别有/d/ /t/ /id/。   而
的过去式的发音则略有不同,但是有些还是按照一定规律变化的。如以上的:make - made,get - got ,buy - bought ,come - came ,fly-flew ,bring-brought,teach-taught, think-thought, say-said,sit-sat. read-read, spend-spent,give-gave,tell-told,write-wrote,feel-felt,find-found,hear-heard,know-knew,put-put,grow-grew,take-took,catch-caught,become-became,swim-swam,sweep—swept,sing—sang,draw—drew
