英语动词有五种基本形式,即动词原形、第三人称单数(现在式)、过去式、过去分词和现在分词.
1.第三人称单数的构成方法
与名词的单数变复数规则大致一样,即：
(1) 一般情况下由动词后加-s构成：work / works,read / reads等.
(2) 以s,x,z,sh,ch 以及字母o结构的动词日夏养花网,后加-es：guess / guesses,mix / mixes,go / goes,buzz / buzzes,finish / finishes,catch / http://www.rixia.cccatches等.
(3) 以辅音字母加y结尾的动词,应将y改为i 再加-es：www.rixia.ccfly / flies,study / studies等.
【注】① 有个别的变化不规则,如have / has,be / is等.
② 词尾-s和-es 读音规则是：在s,x,z,sh,ch 后的es读作[iz],其余的读作[z].
2.过去式和过去分词的构成方法
分规则变化和不规则变化两种.不规则变化需逐个记忆,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].
3.现在分词的构成方法
(1) 一般情况下,在动词后加-ing构成：work / working,sleep / sleeping,wait / waiting等.
(2) 在不发音的-e结尾动词去掉e后再加-ing：smile / smiling,move / moving 等.
(3) 以重读闭音节或r音节结尾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-ing：sit / sitting,plan / planning,refer / referring,occur / occurring等.
(4) 以字母ie结尾的动词,通常将ie改为y,再加ing：die / dying,lie / lying,tie / tying等.
【注】(1) 以字母l结尾动词,若末尾一个音节为重读音节,则必须双写l再加ing,如control / controlling,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)ing.
(2) 名词变复数、形容词和副词变比较级和最高级、动词变过去式和过去分词等都有“改y规则”,但动词的现在分词没有“改y规则”.
(3) 动词picnic(野餐)的现在分词为picnicking,不是picnicing.
望采纳，谢谢！

多数动词的基本形式有四种现在式；过去式；过去分词；现在分词。

1、现在式

动词的现在式即动词原形（如：meet, do, like等），用于祈使句、不定式的时态中的一般现在时，但碰到单数第三人称时，需要在动词原形词尾加-s(其构成法与名词复数的构成法及读单相同，如meets, does, likes, studies。

I live in the center of the town。我住在市中心。

2、过去式

过去式主要用于过去日夏养花网时（不因人称和数而弯化），有规则和不规则两种变化。多数动词都是规则动词，在动词原形之后-ed构成过去式（和 过去分词），如:liked，studied。

I went home at half past five yesterday。

我昨天五点半回家。

3、过去分词

与hava或had构成完成时态，与be构成被动时态。构成情况与过去式相同。例如：developed countries发达国家。

例如：Tom has already passed this exam。

汤姆已经通过了这次考试。

4、现在分词

一般情况在词尾加-ing，如：looking，walking以不发音的字母e结尾的，去掉e后再加-ing，make-making，lose-losing，以重读闭音节结尾，词尾只有一个辅音字母的，双写末尾的辅音字母再加-ing，如：run-running, get-getting, begin-beginning。
