補充說明：

規則動詞的過去式由“動詞原形+-ed”構成,具體變化有：

1.直接在詞尾加-ed.如:want—wanted,

work—worked,need—needed,clean—cleaned

2.以不發音的e結尾的在詞尾加-d.如：like—liked,

live—lived,use—used,move—moved

3.

以一個母音字母加一個子音字母結尾的重讀閉音節動詞,先雙寫結尾的子音字母,再加-ed.如：stop—stopped,

trip—tripped

4.以子音字母加y結尾的動詞,先把y變成i,再加-ed.如：study—studied,carry—carried,

hurry—hurried,marry—married

1.以t結尾的詞,過去式與原形相同.如：put—put,let—let,

cut—cut,beat—beat

2.以d結尾的詞,把d變成t.如:build—built,

lend—lent,send—sent,spend—spent

3.以n結尾的詞,在詞後加t.如：mean—meant,

burn—burnt,learn—learnt

4.以ow / aw結尾的詞,把ow /

aw變成ew.如：blow—blew,draw—drew,know—knew,grow—grew

5.含有雙寫字母的詞,將雙寫改為單寫,在詞尾加t.如：keep—kept,

sleep—slept,feel—felt,smell—smelt

6.含有母音字母o / i的詞,將o / i變成a.如：sing—sang,

give—gave,sit—sat,drink—drank
