It has a long/short tail”對(duì)相應(yīng)的人或物的大小長(zhǎng)短做出正確的描述。為了達(dá)到以上教學(xué)目標(biāo)，我把課堂分成兩部分：long/short的學(xué)習(xí)以及，big 和small的學(xué)習(xí)。按照整體設(shè)計(jì)思路：實(shí)物呈現(xiàn)操練情景操練表演chant的過(guò)程，首先通過(guò)動(dòng)物圖片引出兔子玩偶，兩個(gè)大小不同的兔子引出big 和small。并通過(guò)實(shí)物兔子玩偶引導(dǎo)學(xué)生用I have a rabbit,its big/small.讓學(xué)生在句子中操練新詞。運(yùn)用角色扮演，讓更多的學(xué)生在情景中運(yùn)用句子，達(dá)到操練的目的。讓學(xué)生在chant節(jié)奏鮮明的音樂(lè)中，聽(tīng)，說(shuō)，做相結(jié)合。從呈現(xiàn)到操練
