,Lynn,国际音标,音素 Phoneme 是英语关于语音的最小的单位。英语语音共有48个音素,其中元音音素20个。辅音音素28个,发音时声带振动,气流在通过口腔时不受发音器官阻碍的音素叫元音。元音有单元音和双元音两大类。发音时气流在通过口腔时受到发音器官的阻碍而发出的音素叫辅音。其中声带振动的叫浊辅音,声带不震动的叫清辅音。音标是记录音素的符号。现在我们用国际中的48个音标来记录英语语音。,音素(48个),元音因素(20个),辅音因素(28个),单元音(12个),双元音(8个),清辅音(11个),浊辅音(15个),半元音(2个),音节,音节的概念音节是由元音和辅音字母构成的发音单位。就语 音形式而言,一个音节通常由一个元音音素加上一个或几个辅音字母构成。单独一个元音字母也也可以构成一个音节。但辅音一般不单独构成音节。音节的分类音节包括重读音节和非重读音节。重读音节又分为开音节、闭音节、r 音节和re 音节。,单词的音节 在一个词中,有几个元音因素(不是元音字母),就有几个音节。单词按其音节多少来划分,可分为三种单音节词由一个音节构成的词叫做单音节词,如big,fight,I,you,a 等双音节词由两个音节构成的词叫做双音节词,如worker,teacher,our等。多音节词由三个或三个以上音节构成的词叫作多音节词,如family,afternoon,university等。,开音节:在一个音节中,如果一个元音字母的后面没有辅音字母,或者只有一个辅音字母(r除外),后面又带有一个不读音的字母e,这样的音节叫做开音节。元音字母在开音节中读字母音。,闭音节:在一个音节中,如果一个元音字母的后面只有一个或两个辅音字母(r除外),这样的音节叫做闭音节。元音字母在闭音节中读短音。,Pronunciation,开音节:元音字母+辅音字母+不发音的e,元辅 e 结构,元音字母在开音节中读字母音,闭音节:元音字母+辅音字母,元辅结构,元音字母在闭音节中读短音,26个字母读音,Aa Bb Cc Dd Ee Ff Gge i bi:s i:di:i:ef di:Hh Ii Jj Kk Ll Mm Nneit ai dei kei el em enOo Pp Qq Rr Ss Ttu pi:kju:a:es ti:Uu Vv Ww Xx Yy Zzju:vi:dblju:eks wai zed,A,Dale Grace name age game Jane Dave,/ei/,Frank thank hand Alice Mary Jack map bag cat,/,E,he we green me sea evening meet feet,/i:/,pen yes desk well Helen red seven pencil egg,/e/,/ei/,Grace name eraser case baseball game Jane Dave table take,sale date age make gate hate skate safe same wave grape late,am Alice map black and racket Mary Jack bat backpack hat bag relaxing,bad band bank hand land plan pants sad actor dance dad answer,/,/i:/,he she we evening green these need between please meet three,pen yes desk tennis well dresser Helen yellow spell red seven pencil,/e/,me eat sea east meal team easy beef feel free keep feet sweet,egg help sell tell best wet west left,Kate name grade age cake face game,Ann map bag thank am and apple,元音字母 Aa 在单词中的发音,开音节:,闭音节:,ei,ei 发这个音的字母和字母组合a ai ay a:cake make name game snake gate lazy ai:rain train wait ay:day May play taday way 根据发音规则,圈出下列单词中发音不一样的单词。1.face wave sheep tail 2.grape plane name coat 3.time tape train snake 4.rain soap cake train,发这个音的字母和字母组合a a:dad cap cat bad apple bag flag hand rabbit ant black fat has stand rat map根据发音规则,找出每组中发的单词。1.rat bed face sport 2.hear cup fat pear 3.rice bat finger tree 4.sea young knife apple,he she me tree jeep bee see,egg pen desk pencil yes ten bed,元音字母 Ee 在单词中的发音,e,闭音节:,i:,开音节:,i:发这个音的字母和字母组合e ea ee e:me be she he we evening ee:sweet bee sweep sheep see sleep three green ea:meat leaf sea pea teach eat clean根据发音规则,圈出下列单词中元音字母组合发音相同的两个词。1.seat rain bean cat 2.gift feet teacher dog 3.pig star tree jeep 4.sweet sea fish the,e 发这个音的字母和字母组合e ea e:egg bell desk leg pet ten pen ea:bread head breakfast根据发音规则,找出每组中不发e的单词。1.cat well leg pen 2.sweat map pet elephant 3.egg ten tall desk 4.bread head bed toy,b 发这个音的字母和字母组合b bb b:book ball bird big boy bag banana bb:rubber rabbit cabbage根据发音规则,圈出发b的2个单词。1.cab gift beach love 2.pet god tub bed 3.weather boy bus make 4.rabbit read dress baby,k发这个音的字母和字母组合c k ck c:cap cook cup car can class k:cook milk key desk kite cake ck:clock sock cock neck从下列单词中找出一个发sk的单词。1.cake car desk neck 2.mask rock ink clock 3.disk truck silk duck,s发这个音的字母和字母组合s c ss ce s:star sun snake sea see c:pencil city cedar ceiling celebrate ss:grass glass class boss ce:face race rice nice根据发音规则,圈出每组中2个发s的单词。1.whose juice lick student 2.those case scarf shoes 3.space nose science meat 4.tears piece bus nose,d 发这个音的字母和字母组合d ed d:duck seed door desk day red head bed read cold ed:smiled opened played根据发音规则,圈出没有发d的1个单词。1.bed clothes hand 2.dog cold five 3.dance duck grape,f发这个音的字母和字母组合f ff ph gh f:five fan flower fish four leaf ff:giraffe ph:phone elephant photo gh:laugh选出下列单词中不发f的单词,写在横线上。knife flower foot fish pick get photo giraffe laugh leaf,independent,独立自主,g发这个音的字母和字母组合g gg g:glass golf get girl bag goat flag gg:egg 根据发音规则,圈出发g的单词。gas drive gum give violin bag jeans orange log bridge guess tank grade long language,h发这个音的字母和字母组合h wh h:he her head heart hair ham wh:who whose 根据发音规则,把下列单词中不发h的找出来。1.ham hat white()2.horse whale who()3.wheat hole hair(),
