重读闭音节和过去式过去分词

1、英语动词变过去式和过去分词记忆法 动词可分为规则动词和不规则动词规则动词的过去式和过去分词是一样，变化规则如下：1一般在动词末尾加-ed，如：pull-pulled, cook-cooked2结尾是e加d，如：taste-tasted3末尾只有一个元音字母和一个辅音字母的重读闭音节，应双写末尾的辅音字母，再加-ed，如：stop-stopped注：闭音节是一个元音字母后跟一个或几个辅音字母的单词。闭音节： a)辅音+元音+辅音 例如：bad，bed，sit，hot，cup;b)元音+辅音 例如 it、of;c) 元音+多个辅音 例如： egg ，fish 。重读闭音节：闭音节为重读音节的音节。

2、重读闭音节中元音字母不是发它本身的字母音，而是发短元音。如：:runswim jog sit begin-beginning(重读在gin这个音节上，相当于把gin改成双写的) . 重读闭音节三要素：（1）必须是重读音节；（2）以一个辅音字母结尾；（3）元音字母发短元音。4以“辅音字母+y”结尾的，变y为i， 再加-ed，如：study-studied不规则动词动词过去式和过去分词变化规律如下： 【AAA型】： Cost cost cost cut cut cut put put put read read read set set set shut shut shut hit hit hit

3、 hurt hurt hurt let let let 【ABB型】： (原形aught/oughtaught/ought) catch caught caught teach taught taught bring brought brought buy bought bought think thought thought (原形元音变化元音变化) sit sat sat meet met met find found found get got got stand stood stood understand understood understood win won won hold

4、held held shine shone shone dig dug dug hang hung/hanged hung/hanged (原形 “t” “t”) lose lost lost build built built spill spilt spilt spoil spoilt spoilt send sent sent spend spent spent smell smelt smelt feel felt felt mean meant meant lend lent lent learn learnt/learned learnt/learned (原形 “d” “d”)

5、Make made made have(has) had had pay paid paid say said said lay laid laid sell sold sold tell told told hear heard heard (“ee/ea” “e.t” “e.t”) sweep swept swept keep kept kept leave left left sleep slept slept 【ABC型】： (原形变形原形+en/ne) be(am,is) was been be(are) were been see saw seen do did donego we

6、nt gone beat beat beaten eat ate eaten give gave given hide hid hidden fall fell fallen mistake mistook mistaken take took taken drive drove driven rise rose risen ride rode ridden write wrote written (原形 “-o-” “过去式-n”)break broke broken speak spoke spoken choose chose chosen forget forgot forgotten

7、 freeze froze frozen wake woke/waked woken/waked (原形 “ew” “原形-n”) draw drew drawn blow blew blown show showed shown fly flew flown grow grew grown throw threw thrown know knew known (原形 “-a-” “-u-”) begin began begun ring rang rung drink drank drunk sing sang sung sink sank/sunk sunk/sunken swim swa

8、m swum 【其他】 lie lay lain wear wore worn 【ABA型】 become became become come came come run ran run 【AB型】(无过去分词) May might Must must can could shall should will would 英语重读闭音节就是闭音节为重读音节的音节。重读闭音节中元音字母不是发它本身的字母音，而是发短元音。重读闭音节三要素：（1）必须是重读音节；（2）以一个辅音字母结尾；（3）元音字母发短元音。改变时态时，重读闭音节需要双写末尾辅音字母.如:run-runningswim-swim

9、mingjog-joggingsit-sittingbegin-beginning(重读在gin这个音节上，相当于把gin改成双写的) .像travel这种重读不在vel的，可以为travelled，也可以是traveled.举两个很经典的例子： forbid-forbidding (重读闭音节，双写).prohibit-prohibiting (重读在第二音节，非重读闭音节，不双写).变为过去式时1，重读闭音节也需双写末尾辅音字母如prefer-preferred（重读闭音节，双写）offer-offered（重读第一音节，非重读闭音节，不双写）元音：a e i o u辅音：b d g v

10、r z n p m t c （k g) f l s h j w y q半元音：y2什么叫闭音节单个元音字母后面有辅音字母且以辅音字母结尾的重读音节。就是一个元音字母后跟一个或几个辅音字母的单词。可以这么理解：闭音节： a)辅音+元音+辅音 例如：bad，bed，sit，hot，cup;b)元音+辅音 例如 it、of;c) 元音+多个辅音 例如： egg ，fish 。3重读音节重读音节指的是单词中读音特别响亮的音节。用音标标记双音节、多音节词的读音时，应使用重读符号“”。单音节词多数是重读音节，标记读音时不需要使用重读符号。双音节词的第一个音节通常是重读音节。例如：stu-dent -Chi-na -sec-ond -au-tumn in-deed含有a- be- de- re- in- ex- 等前缀的双音节词往往是在第二个音节上重读。双音节词的重读位置不会因增加前缀或后缀而发生改变。例如：a-bout be-fore ex-cuse re-pair for-get-ful in-ven-tor多音节词通常在倒数第三个音节重读。例如：el-e-phant con-grat-u-la-tion词尾有-ic或-tion,-sion的词，在-ic或-sion,-tion前的一个音节上重读。例如： im-pression republic；emphatic在含有两个以上音节
