若一个动词中有一个元音字母,且最后一个字母是辅音字母,那么双写那个辅音字母再加ed
如drop——dropped

(1)一般情况在动词尾加— ed。例如:
work—worked, want—wanted
(2)以不发音的e结尾的动词,直接加—d。例如:
live—lived, hope—hoped
(3)以“辅音字母+y“结尾的动词,变y为I再加— ed。例如:
study—studied, cry—cried
(4) 以重读闭音节一个辅音字母结尾的动词,双写词尾的辅音字母再加— ed。例如:
stop—stopped, beg—begged.
(5)词尾听加的— ed的发音,有以下几种情况:
a. 以元音或浊辅音结尾的动词。加— ed后,— ed发音浊辅音[d]。
b. 以清辅音结尾的动词,加— ed后,— ed发清辅音[t]。
c. 以[t] [d]结尾的动词,加— ed后,— ed发[id], 与结尾的[t]、[d]相拼,读作[tid]或[did].

blow- blew- blown, draw-drew-drawn, grow-grew-grown, throw-threw-thrown, know-knew-known
六、有些动词的过去分词是在原形词尾加n或en,变成以en结尾的单词。如:

11.以ould结尾且读音为〔ud〕的情态动词过去式。如:
can—could,shall—should,will—would
12.在动词原形后加d或t变成过去式,并且发生音变。如:
hear〔hi 〕—heard〔h :d〕, say〔sei〕—said〔sed〕,
mean〔mi:n〕—meant〔ment〕, dream—dreamt 〔dremt〕
13.动词的过去式与动词原形一样。如:

你说的双写是什么意思?现在分词才有双写的。
