补充说明:


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
