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
