常见动词过去式过去分词的变化规则
1. 以-e结尾的一般在词尾加-d，如live（现在式）→lived（过去式）。

2. 以辅音字母+y结尾的，变y为i，再加-ed，如study（现在式）→studied（过去式）。

3. 以重读闭音节结尾，并且结尾只有一个辅音字母的，双写结尾的辅音字母，再加-ed，如stop（现在式）→stopped（过去式）。

4. 不规则动词，形式不规则，通常需要记忆。

例如：go（现在式）→went（过去式）、eat（现在式）→ate（过去式）。

5. 一部分动词的过去式和过去分词形式是相同的，如cut（切）
→cut（过去式和过去分词）。

需要注意的是，有一些动词的过去式和过去分词形式与现在式相同，所以在句中根据上下文区分时需要仔细观察。

初中英语动词过去式和过去分词变化规则一般地，英语动词的过去式和过去分词的变化规则如下：
1. 大多数动词的过去式和过去分词是在动词原形后加上-ed，例如：
work -> worked -> worked
talk -> talked -> talked
2.以不发音的-e结尾的动词，在后面直接加上-d，例如：
love -> loved -> loved
dance -> danced -> danced
3. 以一个辅音字母结尾的重读闭音节动词，将末尾的辅音字母双写后再加-ed，例如：
stop -> stopped -> stopped
admit -> admitted -> admitted
4. 以辅音字母+y结尾的动词，将y变为i，再加-ed，例如：
study -> studied -> studied
try -> tried -> tried
5.一些不规则动词的过去式和过去分词形式并不遵循以上规则，需要通过记忆：
go -> went -> gone
be -> was/were -> been
have -> had -> had
请注意，以上是一般的规则，但也有一些特殊的不规则动词需要特别记忆。

动词过去式、过去分词变化规则
（一）分规则变化和不规则变化两种.不规则变化需逐个记忆
（二）规则变化遵循以下原则：
(1) 一般情况下,在动词后加ed
构成：work / worked,stay /
stayed,shout / shouted等.
(2) 在以-e结尾动词后只加d：
close / closed,like /
liked,live / lived,smile /
smiled等.
(3) 以辅音字母加y结尾的动词,应将y改为i 再加-ed：study / studied,carry / carried等.
(4) 以重读闭音节或r音节结尾且(中间只有一个元音字母）且末尾只有一个辅音字母动词,要双写末尾的辅音字母再加-ed：stop / stopped,admit / admitted,refer /
referred,prefer / preferred 等.
【注】(1) 以字母l结尾的动词,若末尾一个音节为重读音节,则必须双写l再加-ed,如control / controlled,但若末尾一个音节为非重读音节,则可双写l(英国英语)或不双写l(美国英语),如travel / travel(l)ed.
(2) 动词picnic(野餐)的过去式和过去分词是picnicked,不是picniced.
(3) 词尾-ed 读音规则是：在清辅音后读作[t],元音和浊辅音后读作[d],在辅音[t]或[d]后读作[id].

动词过去式过去分词的变化规则
动词的过去式和过去分词的变化规则主要分为以下几种情况：
1. 一般情况下，动词过去式和过去分词都在动词词尾加上-ed。

例如：work（工作）→ worked（过去式）、worked（过去分词）。

2. 以辅音字母+y结尾的动词，在动词词尾的y变为i，再加-ed。

例如：study（学习）→ studied（过去式）、studied（过去分词）。

3. 以“辅音字母+元音字母+辅音字母”结尾的重读闭音节动词，需
要先双写最后一个辅音字母，再加-ed。

例如：stop（停止）→ stopped （过去式）、stopped（过去分词）。

4. 以“辅音字母+元音字母+辅音字母”结尾的非重读闭音节动词，
只需在动词词尾加上-ed。

例如：open（打开）→ opened（过去式）、opened（过去分词）。

5. 一些不规则动词的过去式和过去分词需要根据具体动词的不规则
变化规则来决定。

例如：go（去）→ went（过去式）、gone（过去分词）；be（是）→ was/were（过去式）、been（过去分词）。

需要注意的是，英语中存在一些不规则动词，其过去式和过去分词形
式不遵循以上规则，需要单独记忆。

动词过去式和过去分词改变规则：动词过去式和过去分词有规则改变和不规则改变两种。

规则改变:1. 通常情况直接加ed，如ask—asked, work—worked2. 以不发音e结尾，只加d，如love—loved, dance—danced3. 以辅音字母加y结尾，把y变为i，再加ed，如try—tried, study—studied4. 以一个元音字母和一个辅音结尾重读闭音节结尾动词(以重读闭音节或r音节结尾而末尾只有一个辅音字母),先双写末尾这个辅音字母,再加ed,如stop—stopped, permit—permitted 现在分词改变规则：1、通常在词尾加-ing（通常-ing）。

比如：going，playing，knowing2、以不发音字母e结尾，先去e再加-ing（去e）。

比如：making，arriving，coming3、以重读闭音节结尾，且词尾只有一个辅音字母时，先双写这个辅音字母，再加-ing（重闭单辅先双写）。

比如：running，stopping，preferring4、以-ie结尾，先将-ie改成y，再加-ing。

比如：tying，dying, lying口诀：现在进行ing,以e 结尾要去e，除去多个特殊词，系住tie-tying死去die-dying要躺下lie-lying，直接ie变成y,一元一辅双写辅（单音节词）。

把原形变单数第三人称方法1、通常情况加S2、以s,x,ch,sh,o结尾加es3、y前是辅音改y为i加es4、特殊情况have变has规则可数名词复数改变规则：1.通常情况加s ：book-- books mouth---mouths house---houses girl---girls2.以s 、sh 、ch 、x结尾加es ：class--- classes box----boxes match----matches3.辅音字母+ y结尾变y为i加es：city---cities country----countries party----parties factory----factories4.以o 结尾词+es只有以下词：heroes Negroes tomatoes potatoes zeroes/zeros以o 结尾而且词尾有两个元音字母+s radios, zoos, bamboos ,(pianos ,kilos photos)5.以f，fe 结尾变f或fe为v +es ：一、人称代词表示“我”、“你”、“她”、“她”、“它”、“我们”、“你们”、“她们”词，叫做人称代词。

动词过去式与过去分词规则
动词的过去式和过去分词通常需要遵循以下规则：
1. 以-e结尾的动词直接加-d或-ed作为过去式和过去分词。

例如：live（居住）的过去式和过去分词都是lived（居住过）。

2. 以辅音字母加-y结尾的动词，先将-y变为-i，再加-ed作为过去式和过去分词。

例如：study（学习）的过去式和过去分词都是studied （学习过）。

3. 以重读闭音节结尾的单词，如果末尾只有一个辅音字母，并且这个辅音字母前只有一个元音字母，则双写这个辅音字母，并加-ed作为过去式和过去分词。

例如：stop（停止）的过去式和过去分词都是stopped （停止过）。

4. 部分不规则动词，过去式和过去分词形式不按规则变化。

例如：go（去）的过去式是went（去过），过去分词是gone（已去）。

需要注意的是，英语中有很多不规则动词，它们的过去式和过去分词形式没有明确的规则可循，需要通过学习和记忆来掌握。
