英语辅音连缀PPT课件

-,1,英语辅音连缀,英语辅音,-,2,英语单词中两个或两个以上辅音连在一起称为辅音连缀，如desk/desk/中的/sk/,friend/frend/中的/fr/,以及/spri/中的/spr/等。辅音连缀经常发生在词首和词尾。,-,3,一、辅音连缀读法详解1、一般读法在朗读时，辅音连缀中任何两个辅音间都不能加上元音，如：把/frend/读成/frend/就不对了。正确的方法是：第一个音（或第一、第二个音）要读得轻而短，很快过渡到第二个音（或第三个音）上去。,-,4,2、/s/后面爆破音的读法当清辅音/p/t/k/在/s/后面时，无论所属音节重读与否，都不送气，发音类似于它们各自相对应的浊辅音，但又不完全相同，区别在于：它们发音时声带不振动。如：school/sgu:l/,student/sdju:dnt/,spring/sbri/等。,-,5,3、词尾加-s,-es,-ed后的读法一般情况下，可遵循以下规则：清对清，浊对浊，元音也对浊。也就是说，词尾音是清辅音的，加了-s或ed之后，就发清辅音/s/或/t/;词尾音是浊辅音或元音的，加了-s或ed之后，就发浊辅音/z/或/d/。如：books/buks/,bag/bgz/,knows/nuz/,asked/skt/,love/lvd/等。,-,6,词尾音为/t/d/，加-s后，分别读成/ts/和/dz/,如：cats/kts/，gifts/gifts/,reads/ri:dz/,ends/endz/等;,-,7,词尾音为/t/d/，加-ed后，分别读成/tid/和/did/,如：invited/invaitid/，visited/visited/，needed/ni:did/，pretended/pritendid/等；;,-,8,词尾音为/s/z/t/d/等，加-es后读/-iz/，如：boxes/bksiz/,sizes/saiziz/,wishes/wiiz/,watches/wtiz/,bridges/bridiz/等。,-,9,二、辅音连缀发音训练1、词首连缀/-l/bl/blueblowblackblushblowblock/kl/climbclaimcliqueclockclerkclose/fl/flyflowfleefleshflingflat/gl/glassglideglowgladglobeglory/pl/playpleaseplotplanplentyplug,-,10,/-r/br/breadbreakbrokebringbrightbrother/kr/crycreamcrushcroakcradlecrack/dr/dreaddrydrilldreamdressdrive/fr/fromframefrankfreeFrenchfrail/gr/greengrowgreatgrassgrabgrade,-,11,/pr/praypressprintprundpreparepractice/tr/trytreetraintrucktreattroubletropical/r/threethrowthreatthroughthroatthrob（跳动）/r/shriek（尖叫）shrill（尖叫）shrinkshrewd（厉害）shrimp（虾）,-,12,/s-/sp/spyspeakspitsparksportspade/st/staystealstillsteakstarstorystand/sk/skyskisketch（草图）schoolscoldskate/sf/sphere(圆体)sphinx（狮身人面像）spherical(天体的)/sl/sleepslid（滑动）slowslimslot（缝）slum（贫,-,13,/sm/smallsmilesmokesmithsmack（咂嘴）smart/sn/snowsneezesnakesnap（拉断）snatch（抓住）/spr/springspray（喷洒）sprout（发芽）spruce（潇洒的）spreadsprinkle（洒，撒）/skw/squaresqueeze（挤）squat（蹲）squint（斜视）squeak（尖叫）,-,14,/str/stringstrongstreetstraightstride（大步走）/skr/screamscrew（螺旋）script（手稿）scroll（卷轴）scratch（抓，挠）/spl/spleen（脾脏）splay（展开）splash（溅泼）splendidsplint（夹板）,-,15,/-w/dw/dwelldwarf（矮子）dwindle（减少）/kw/quitequickquitquotequeenquiver（抖动）/sw/sweatswear（骂人）swap（交换）swag（摇晃）sway（倾斜）swerve（突然转向）/tw/twicetwintwelvetwisttwinkletwenty,-,16,2、词尾连缀清辅音+s/-s/capslipsbooksroofssmiths（铁匠）desks浊辅音+s/-z/dogspigscabsribsleavesprovesclothesharmssonsmeansgirlsmilessingssongs,-,17,元音+s/-z/playsobeysbuysstaysknowstriesgoest+s/ts/testsrestsbeastsfeasts（宴会）boasts（自夸）hosts（主人）giftsshifts（轮班）listsd+s/dz/fieldsshields（盾牌）wields（挥动）folds（折叠）holdsendsspendspretends（假装）extends（延伸）,-,18,清辅音+ed/-t/stoppedsteppedaskedkickedkissedmissedwashedFinishedwatchedtouched,-,19,浊辅音+ed/-d/robbedrubbedbeggedhuggedlovedmovedseizedseemedharmedlearnedburnedlongedbangedcalledsmiled,-,20,t+ed/tid/inventedinvitedvisitedexpectedwantedrespectedinspectedrelatedsuspectedlastedd+ed/did/needednoddedsurroundedpretendedendedextendedfoldedmendedspeededcrowded,-,21,s/s/-s
