规则动词的过去式由“动词原形+-ed”构成,具体变化有:
1. 直接在词尾加-ed。如: want—wanted, work—worked, need—needed, clean—cleaned
2. 以不发音的e结尾的在词尾加-d。如:like—liked, live—lived, use—used, move—moved
3. 以一个元音字母加一个辅音字母结尾的重读闭音节动词,先双写结尾的辅音字母,再加-ed。如:stop—stopped, trip—tripped
4. 以辅音字母加y结尾的动词,先把y变成i,再加-ed。如:study—studied, carry—carried, hurry—hurried, marry—married

不规则动词的过去式见课本后的不规则动词表。大体上归纳有以下六条记忆法:
1. 以t结尾的词,过去式与原形相同。如:put—put, let—let, cut—cut, beat—beat
2. 以d结尾的词,把d变成t。如:build—built, lend—lent, send—sent, spend—spent
3. 以n结尾的词,在词后加t。如:mean—meant, burn—burnt, learn—learnt
4. 以ow / aw结尾的词,把ow / aw变成ew。如:blow—blew, draw—drew, know—knew, grow—grew
5. 含有双写字母的词,将双写改为单写,在词尾加t。如:keep—kept, sleep—slept, feel—felt, smell—smelt
6. 含有元音字母o / i的词,将o / i变成a。如:sing—sang, give—gave, sit—sat, drink—drank

规则动词词尾加-ed有三种读音:
1. 在清辅音后读作[t]。如:asked, helped, watched, stopped
2在浊辅音和元音后读作[d]。如:enjoyed, studied, moved, called
3. 在t / d后读作[id]。如:wanted, needed

现在分词的构成方法如下 : 一般情况下,直接在动词原形后面加 -ing.
going asking finding working being seeing printing raining standing studying speaking spelling
以不发音的-e 结尾的动词,去-e ,再加-ing。 coming taking firing encircling writing becoming breathing leaving
闭音节的单音节词,或以重读闭音节结尾的多音节词,这些词的末尾只有一个辅音字母时,双写这个辅音字母,再加 -ing.
sitting running getting cutting stopping beginning planning permitting


一般现在时主语单三人称时的动词变化
①在一般现在时中,当主语为第三人称单数时,动词要用“s”型(即第三人称单数形式)。
②所谓动词“s”型的构成,可按名词变复数的规则来记,即:
i)在动词尾直接加 s。如:
play—plays, want—wants, work—works, know—knows, help—helps,get—gets
ii)以字母s、x、ch或o结尾的动词加-es;如:
guess—guesses, fix—fixes, teach—teaches, brush—brushes, go—goes,do—does,watch—watches,catch—catches

iii)以辅音字母+y结尾的动词,先变y为i,再加-es。如:
study—studies,carry—carries,fly—flies,worry—worries
