元音+/輔音+元音2、二分開(kāi)：當(dāng)兩個(gè)元音字母之間有兩個(gè)輔音字母時(shí)，一般把它們分開(kāi)，一邊一個(gè)。如：af/ter，cor/nersum/mer，bet/ter，com/mon

元音+輔音/輔音+元音3、輔音連綴不分開(kāi)：輔音連綴不分開(kāi)，必須劃在一個(gè)音節(jié)里。如pr/tr/dr/fl/cl/sp/sw/scr等，不能分開(kāi)，一般劃歸后面的音節(jié)。如：如a/gree，re/flect,in/stant4、字母組合手牽手：（1）輔音字母組合劃分音節(jié)時(shí)不能分開(kāi)。如：tea/cher,fa/ther（2）如果兩個(gè)元音字母組合或者一個(gè)元音字母和一個(gè)半元音字母構(gòu)成的組合發(fā)的是一個(gè)單元音或雙元音，劃分音節(jié)時(shí)，不能將其從中分開(kāi)，要?jiǎng)澰谝黄?。如：trou/sersvoy/agetow/er5、雙字相連不連手：英語(yǔ)里的合成詞，如how/ever，birth/daywork/shop等，原始的兩個(gè)單詞一般分開(kāi)發(fā)音；若兩個(gè)單詞的頭尾相連字母是字母組合或輔音連綴，仍然要拆開(kāi)發(fā)音。如restroom中間的tr,不能發(fā)[tr]。6、前綴后綴獨(dú)自走：前綴或后綴單獨(dú)劃分音節(jié)。如：dis/like，pass/a/ble

輔音字母+le結(jié)尾，應(yīng)看做一個(gè)音節(jié)。音節(jié)是讀音的基本單位。音節(jié)的核心是元音，元音可單獨(dú)構(gòu)成音節(jié)，也可以與輔音一起構(gòu)成音節(jié)。兩個(gè)輔音字母之間不管有多少個(gè)元音字母，一般都是一個(gè)音節(jié)。不可拆分的字母組合：th,sh,ch,tch,ck,cr,pr,bl,fl等。Attention2syllablespa-cket3syllablesche-mi-calin-sideca-bleex-am-pleen-er-gyA1Lookatthesyllablesbelow.Combinethemintowordswithhyphen(-).A2Saythesewords.Thenwritethenumberofsyllablesinbrackets.5.candle ()6.dangerous ()7.bettery ()8.American ()1.newspaper ()2.hear ()3.able ()4.anyone ()23343123Dividethewordsintosyllables:tidyreplylockconversationpopulationcongratulationtelecommunicationti-dyre-plylockcon-ver-sa-tionpo-pu-la-tioncon-gra-tu-la-tionte-le-com-mu-ni-ca-tionExerciseWhatistheboygoingtodo?
