英语中,过去式与过去分词的区别和用法
表示一般过去式的动词通常用动词的过去式形式来表示,而动词的过去式是在动词原形的基础上变化的.动词的过去式可分为规则动词和不规则动词.规则动词的过去式变化如下:
(1)一般情况下,动词词尾加 -ed ,如:
worked played wanted acted
(2)以不发音的 -e 结尾动词,动词词尾加 -d,如:
lived moved decided declined hoped judged raised wiped
(3)以辅音字母 + y结尾的动词,把-y变为-i 再加-ed,如:
studied tried copied justified cried carried embodied emptied
(4)以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,再加 -ed,如:
stopped begged fretted dragged dropped planned dotted dripped
(5)注:不规则动词的过去式变化规律性不强,须多加记忆.
go - went,make - made, get - got ,buy - bought ,come - came ,fly-flew ,is/am-was, are-were ,see-saw ,bring-brought,do-did,teach-taught, think-thought, are-were, say-said,sit-sat. read-read, spend-spent.(部分)
1 、规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同.四点变化规则:
(1)、一般动词,在词尾直接加“ ed ”.
work---worked---worked ,visit---visited---visited
(2)、以“ e ”结尾的动词,只在词尾加“ d ”.
live---lived---lived ,
(3)、以“辅音字母 + y ”结尾的动词,将 "y" 变为 "i" ,再加“ ed ”.
study---studied---studied ,cry---cried---cried ,
(4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”.
stop---stopped---stopped , drop---dropped--dropped
