现在进行时 动词加ing的变化规律
1)一般情况下,直接加 -ing:
如:go—going answer—answering study—studying be—being see—seeing
[注一] 和名词复数、一般现在时动词第三人称单数加-s(-es)不同,动词末尾如为“辅音字母 + y”时,y不变,其后直接加ing.如:study—studying fly—flying
carry—carrying
[注二] 动词结尾为辅音字母r时,加-ing,r在此必须发音.如:water—watering answer—answering wear—wearing
2)以不发音的e结尾的动词,去掉e,再加ing 如:come—coming write—writing take—taking
become—becoming
3)动词是闭音节的单音节词,或是以重读闭音节结尾的多音节词,而末尾只有一个辅音字母时,这个辅音字母须双写,然后再加ing.如:sit—sitting run—running stop—stopping begin—beginning admit—admitting forget—forgetting
[注一] send,think,accept等动词虽是闭音节或以重读闭音节结尾,
但末尾有一个以上的辅音字母,因此,这个辅音字母不双写,应直接加ing.如:sending thinking accepting
4)少数几个以-ie结尾的动词,须将ie变作y,再加ing.如:die—dying tie—tying
lie—lying躺,说谎
5)少数以-c结尾的动词变为现在分词时和过去式,须先将-c变为ck,然后再加-ing 或-ed .
如:picnic—picnicking (picnicked) traffic—trafficking (trafficked)
1.英语重读闭音节就是所谓的元音字母不是发它本身的字母音,重读闭音节就是
指在一个音节中,以辅音音素结尾的而且是重读音节的音节 (重读闭音节即两个辅音中间夹一个元音).
2.元音:a e i o u(其它为辅音)
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)
