现在分词的变化规律-供参考

1、现在分词的变化规律1 一般情况下，直接在动词后加-ing work - working sleep - sleeping study - studying2 动词以不发音的-e结尾，要去-e加-ing take - taking make - making dance - dancing3 闭音节的单音节词，或以重读闭音节结尾的多音节词，这些词的末尾只有一个辅音字母时，双写这个辅音字母，再加 -ing.cut - cutting put - putting begin - beginning 4 以-ie结尾的动词，把ie变成y再加-inglie - lying tie - tying die

2、 - dying动词的过去式变化规律规则动词的过去式由“动词原形+-ed”构成，具体变化有：直接在词尾加-ed。wantwanted,workworked,needneededcleancleaned 以不发音的e结尾的在词尾加-d。如：likeliked,livelived, useused, movemoved 以一个元音字母加一个 HYPERLINK /s?q=%E8%BE%85%E9%9F%B3%E5%AD%97%E6%AF%8D&ie=utf-8&src=wenda_link t _blank 辅音字母结尾的 HYPERLINK /s?q=%E9%87%8D%E8%AF%BB%E9%

3、97%AD%E9%9F%B3%E8%8A%82&ie=utf-8&src=wenda_link t _blank 重读闭音节动词，先双写结尾的辅音字母，再加-ed。如：stopstopped, triptripped 以辅音字母加y结尾的动词，先把y变成i，再加-ed。如：studystudied, carrycarried, hurryhurried, marrymarried不规则动词的过去式见课本后的不规则动词表。大体上归纳有以下六条记忆法：以t结尾的词，过去式与原形相同。如：putput, letlet, cutcut, beatbeat 以d结尾的词，把d变成t。如:buildbui

4、lt, lendlent, sendsent, spendspent 以n结尾的词，在词后加t。如：meanmeantburnburnt,learnlearnt 以ow / aw结尾的词，把ow / aw变成ew。如：blowblew, drawdrew, knowknew, growgrew 含有双写字母的词，将双写改为单写，在词尾加t。如：keepkept,sleepslept, feelfelt, smellsmelt 含有 HYPERLINK /s?q=%E5%85%83%E9%9F%B3%E5%AD%97%E6%AF%8D&ie=utf-8&src=wenda_link t _bla

5、nk 元音字母o / i的词，将o / i变成a。如：singsang,givegave, sitsat, drinkdrank 规则动词词尾加-ed有三种读音： 在 HYPERLINK /s?q=%E6%B8%85%E8%BE%85%E9%9F%B3&ie=utf-8&src=wenda_link t _blank 清辅音后读作t。如：asked, helped, watched, stopped 在 HYPERLINK /s?q=%E6%B5%8A%E8%BE%85%E9%9F%B3&ie=utf-8&src=wenda_link t _blank 浊辅音和元音后读作d。如：enjoyed

6、, studied, moved, called 在t / d后读作id。如：wanted, needed动词的三单变化规律一般现在时主语单三人称时的动词变化 在一般现在时中，当主语为第三人称单数时，动词要用“s”型（即第三人称单数形式）。 所谓动词“s”型的构成，可按名词变复数的规则来记，即： 在动词尾直接加 s。如： playplays， wantwants， workworks， knowknows， helphelps，getgets 以字母s、x、ch或o结尾的动词加-es；如： guessguesses， fixfixes， teachteaches， brushbrushes，

7、gogoes，dodoes，watchwatches，catchcatches 以辅音字母y结尾的动词，先变y为i，再加-es。如：studystudies，carrycarries，flyflies，worryworries 强调如何将主语是第三人称单数的肯定句变为否定和疑问句。现举例说明（用划线部分来说明顺口溜）： His mother works in a factory His mother doesnt work in a factory Does his mother work in a factory？Mr Li teaches us English Mr Li doesnt teach us English Does Mr Li teach you English？ My brother studies maths well
