．不规则动词的词形变化
定义 动词由原形转变为过去式和过去分词时不按词尾加“-ed”之变化规则者叫做不规则动词（Irregular Verbs）。
现代英语新生成的动词都归入“-ed”的规则变化，例如：
park→parked （停车——1864）
fax→faxed （以传真传送——1979）
e-mail→e-mailed （以电脑网络传送——1982）
（所附年次为最早用例出现年次——O.E.D.）
因此，不规则动词可以说都是古英语动词的不规则变化因其常用度很高而一直沿用到今天者，所以我们今天在学习英语时绝对无法，也不可能规避这些不规则动词。
从英语的演变来看，不规则动词就是强势动词（Strong Verbs）——即其词形变化全依其本身之语音（尤其是元音）变化来进行而不借助词尾的变化。例如：
原形： buy sing speak
过去式： bought sang spoke
过去分词： bought sung spoken
而每一型式的变化都有其类群，例如：
buy bought bought （买）
bring brought brought （带来）
fight fought fought （作战）
think thought thought （想）
sing sang sung （唱）
drink drank drunk （喝）
swim swam swum （游泳）
begin began begun （开始）
speak spoke spoken （说）
break broke broken （打破）
steal stole stolen （偷）
freeze froze frozen （冷冻）
因此我们学习不规则动词的时候，最有效的方法就是要针对这种词形变化的现象，了解其变化的型式，发出声音背念，使其能自然地隔入我们的speaking和writing，这样才能说确实地把不规则动词学会了。
注：与强势动词相对，须借助“-ed”之词尾来进行词形变化的规则动词就叫做弱势动词（Weak Verbs）。
不规则动词的类别
每个学习英语的人都会在不同阶段或多或少碰到不规则动词所带来的麻烦，特别是在形态拼写方面。
不规则动词里是不是杂乱无序的动词呢？当然不是；实际上是乱中有序、有条不紊的。
首先，不规则动词是针对规则动词而言。
大家知道，规则动词（regular verbs）的过去式（the past form）和过去分词（the past
participle）都一样的要加上“ -ed/-d”，如：
①a. Jason worked until five o'clock（过去式）
b. Have you worked late?（过去分词）
②a. Xiao Lin decided to go abroad（过去式）
b. Has his wife decided to join him ?（过去分词）
不规则动词则不然；它们的过去式和过去分词并不一致，学习时要集中精神，加以辨别，才可避免错误。
语法学家根据动词“原形、过去式、过去分词”三形式上的变化，把不规则动词划分为下列类别：
一 三种形式都相同
第一类的包括下列这些常见动词：
① cut-cut-cut ; ② hurt-hurt-hurt ; ③ put-put-put; ④ shut-shut-shut; ⑤
cost-cost-cost; ⑥burst-burst-burst; ⑦ hit-hit-hit; ⑧ cast-cast-cast; ⑨
set-set-set; ⑩ let-let-let。
例如：
⑴a. Don't go on blowing the balloon! It will burst.
b. One of his car tyres had a nail and it burst.
c. The dog has burst free and ran away.
二 其中两种形式相同
第二类可分为十一小类；下面是其中常见的四种：
① bind-bound-bound; find-found-found
② bring-brought-brought;
think-thought-thought
③ dig-dug-dug; strike-struck-struck
④ bend-bent-bent; build-built-built
例如：
⑵a. You have to bend your head when you bow.
b The mechanic bent the wire and broke it.
c. Here come the woman bent down with age.
三 三种形式都不同
第三类可再分为八小类，如下：
① take-took-taken; shake-shook-shaken
② hide-hid-hidden; bite-bit-bitten
③ tear-tore-torn; bear-bore-born/ borne
④ choose-chose-chosen;
speak-spoke-spoken
⑤ know-knew-known; blow-blew-blown
⑥ write-wrote-written; drive-drove-driven
⑦ drink-drank-drunk; begin-began-begun
⑧ show-showed-showed/shown;
swell-swelled/swollen
例如：
⑶a. Can you write down your name?
b. I wrote it there, didn't I?
c. Have you written to John, who is now in New York?
上述例子证明不规则动词的确比规则动词麻烦得多。莫怪有人说，英语动词是所有词类中，最难应付的一种。这话很中肯，毫不夸张。幸好，不规则动词也有迹可寻；就让我们“步步追踪”吧！
不规则变化动词的过去式：： (第二册第七课)Q & A 集锦康轩版相关课程翰林版相关课程
除了 be 外，动词中，其过去式呈不规则变化者，从第一册到本课，计有：
原形动词-过去式 原形动词-过去式
do-did draw-drew
drive-drove cut-cut
come-came eat-ate
fight-fought find-found
get-got give-gave
go-went have-had
hide-hid make-made
put-put read-read [rεd]
ring-rang run-run
say-said see-saw
shine-shone sing-sang
speak-spoke swim-swam
take-took tell-told
write-wrote feel-felt
hear-heard
这种不规则变化动词，因为是呈现不规则变化，故只能看到一个就记一个，无其他办法，但重要的是，要背得滚瓜烂熟。
比较特殊的是，have和has的过去式，均是had，但仍以have为其「原形动词」；do和does亦同，它们的过去式均为did，但仍以do为其「原形动词」。又read的过去式也是read，只是读法不同罢了。
须视句中意思，才能决定是否为过去时间者：有些时间，到底是属於「现在」，还是「过去」，或者是「未来」，须得看上下文来决定。
today（今天）
this morning/afternoon/evening（今天早上/下午/晚上）
如：
我今天早上八点来的。（显然是指已发生过的事。）——过去
我今天早上八点才会去。 （句中意思可见还没去。）——未来
过去式一般动词的否定句、疑问句和简答句的形成：
在谈这个主题之前，先来复习第一册第四、七课和第一册第八课所学过的：
否定句：
I have a dog. → I don't have a dog.
They have ten cards. → They don't have ten cards.
She loves cats. → She doesn't love cats. (注意love的变化——恢复为原形)
疑问句：
I have a dog. → Do you have a dog?
They have ten cards. → Do they have ten cards?
She loves cats. → Does she love cats? (注意love的变化——恢复为原形)
想想看：do/does 的过去式为 did，而 did 和 do/does 一样，均为助动词，故其后的动词须注意什麼变化？（参考前述的例句）
所以若是像这样的过去式动词的否定句变化，就会如下列例句：
否定句：
1. Mary wrote her homework last Sunday. → Mary didn't writeher homework
last Sunday.
2. Mr. Wang drove his car to the park. → Mr. Wang didn't drive his car to
the park.
3. Tom made the wish last year. → Tom didn't make the wish last year.
4. The students saw some dogs at school yesterday.
→ The students didn't see some dogs at school yesterday.
想想看：在现在式中，助动词的使用有分人称，而分别使用 do/does；从以上的例句中，请问过去式助动词 did
的使用，是否也因人称的不同，而使用不同的过去式助动词？
疑问句：在对照现在式中使用 do/does，及在过去式中使用 did 等助动词，形成否定句的用法，你是否可以将下列各过去式的句子，改为疑问句呢？
5. Mary went to the park by bicycle.
6. Mr. Wang took the MRT to school.
7. Tom made the wish last year.
8. The students saw some dogs at school yesterday.
9. We got the umbrella this morning.
简答句：你做对了吗？其实过去式的否定句和疑问句的写法，比现在式要简单得多，因为它根本无须考虑到人称的问题。依此推想，则你是否可写出上述五句的
Yes/No 的简答句了呢？
10.Yes,No,
11.Yes,No,
12.Yes,No,
13.Yes,No,
14.Yes,No,
▲在此要特别提出说明的是 do 的用法，因 do 有两个意义，当动词用时解释为「做」，另也可当作「助动词」使用，故在做句型变化时，常见有错误的现象：
4. He did his housework yesterday.（他昨天做了家事。）—— did 是动词。
5. Did he do his housework yesterday?（他昨天有做家事吗？）
—— did 是助动词，原动词则因助动词 did 的关系，恢复为原形动词。
6. He didn't do his housework yesterday.（他昨天没有做家事。）
—— didn't 是助动词 did 和 not 的缩写，原动词则因助动词 did 的关系，恢复为原形动词。
想想看：试将底下的句子翻译成英文。
1. 那些学生昨天并没有在学校游泳。
2. 上周四 Jack 教他的弟弟英语。
3. 今天下午 Coco 开车去台北吗？
4. 我今天早餐喝牛乳。
5. Jimmy 没有在早上六点起床过
