动词词尾加--ed的三种读音

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, need

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—need, 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
