字母組合br和gr的發(fā)音規(guī)則br和gr是常見的字母組合，在英語中有著不同的發(fā)音規(guī)則，其中,br通常發(fā)/b/和/r/兩個(gè)音，而gr通常發(fā)/g/和/r/兩個(gè)音。gr和br發(fā)音的區(qū)別：gr發(fā)音時(shí)，是舌根音，br是雙唇音。br與gr的發(fā)音口決：1.br讀音口訣：

嘴唇緊閉，空氣停滯，然后爆破發(fā)音,b-r的發(fā)音就呈現(xiàn)出來.2.gr讀音口訣：舌頭抵住上腭，喉嚨發(fā)出濁音,g-r的發(fā)音就實(shí)現(xiàn)了。Let’slearn.Let’schant.Greengrapesgrow.Greengrapesgrow.Grandpaandmybrotherwatchgreengrapesgrow.Brownbreadbakes.Brownbreadbakes.GrandmaandmybrotherwatchBrownbreadbakes.聽到gr時(shí)坐正，聽到br時(shí)拍下手。Readandgroup.greenbrowngrowgrandmabreakfastbrothergrassgrapeslibrarygreatbrowngreenbrgrbreakfastbrotherlibrarygrowgrandpagrassgrapesgreatChoose,writeandsay.GrandpaGrandmagrowsgreengrapes.orangepotatoes.browngrasspurpleapples.Grandpagrowsgreengrapes1.________________________.2._________________________.Groupwork:1.小組討論如何連詞成句。2.將所造句子認(rèn)真寫入橫向線內(nèi)(大寫、空隙、標(biāo)點(diǎn))Grandmagrowspurplegrapes將全班分成八個(gè)人一組，每個(gè)小組排成一個(gè)長隊(duì)，請第一位學(xué)生選其中一個(gè)詞，小聲告訴下一位學(xué)生，如此這樣，直到小聲傳到本隊(duì)的最后一名學(xué)生時(shí)，就請這位最后的學(xué)生大聲說出他所聽到的單詞，然后請第一名學(xué)生也大聲說出自己剛一開始傳給第二名學(xué)生的單詞，這樣就可以判斷出他們一組，每個(gè)組員是否都傳遞了正確的讀音。PassingWords.green browngrow grandmabreakfastbrothergrass grapeslibrary greatPlayagame.了解br,gr的發(fā)音規(guī)則記憶br,gr的發(fā)音規(guī)則根據(jù)發(fā)音規(guī)則讀出生詞一、判斷劃線部分讀音是（T）否（F）相同()1.A.green B.grass C.brown()2.A.great B.glass C.grate()3.A.break B.bring C.library()4.A.umbrella B.brother
