如果单词以元音字母(a,e,i,o,u)加 y 以外的其他辅音字母结尾的,要双写最后一个字母加ed,像stop,drop,要写成stopped,dropped。\r\n 规则动词的过去式由“动词原形+ed”构成,具体变化有:\r\n 1. 直接在词尾加-ed。如: want—wanted, work—worked, need—needed, clean—cleaned;\r\n 2. 以不发音的e结尾的在词尾加-d。如:like—liked, live—lived, use—used, move—moved;\r\n 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;\r\n 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.\r\n 不规则动词的过去式大体上归纳有以下六条记忆法:\r\n 1. 以t结尾的词,过去式与原形相同。如:put—put, let—let, cut—cut, beat—beat;\r\n 2. 以d结尾的词,把d变成t。如:build—built, lend—lent, send—sent, spend—spent;\r\n 3. 以n结尾的词,在词后加t。如:mean—meant, burn—burnt, learn—learnt;\r\n 4. 以ow / aw结尾的词,把ow / aw变成ew。如:blow—blew, draw—drew, know—knew, grow—grew;\r\n 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;\r\n 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。
