过去式的发音规则
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、其他辅音和元音后读作[d]。如:enjoyed, studied, moved, called 3.在t / d后读作[id]。如:wanted, needed 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
1 / 2
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
2 / 2
