Unit4 At the farm B . Lets learnDraw and say 教學(xué)設(shè)計(jì)一、教材分析：本單元圍繞“At the farm”這一題材展開，學(xué)習(xí)農(nóng)場(chǎng)里的蔬菜和動(dòng)物，以及單、復(fù)數(shù)的使用習(xí)慣。本課時(shí)是本單元的第五課時(shí)詞匯教學(xué)課。重點(diǎn)學(xué)習(xí)的單詞是cow, hen, horse和sheep,還有它們的復(fù)數(shù)形式變化cow cows, hen hens, horse horses和sheep sheep,并能簡(jiǎn)單地描述動(dòng)物的特征，如：These are sheep. Wow! Theyre so cute!學(xué)生能夠理解名詞的單復(fù)數(shù)變化，并能正確地運(yùn)用。尤其要注意sheep sheep這個(gè)單詞的復(fù)數(shù)形式比較特別，本課時(shí)不打算深入探討名詞的單復(fù)數(shù)變化規(guī)律，只要求學(xué)生記住就行了。因此，在授課的過(guò)程中，運(yùn)用以舊帶新的方法自然引出新課內(nèi)容，讓學(xué)生新舊結(jié)合、不斷積累，將所學(xué)的語(yǔ)言用于生活。二、學(xué)情分析：學(xué)生從三年級(jí)開始學(xué)習(xí)PEP英語(yǔ)，已經(jīng)具備了一定的口語(yǔ)表達(dá)能力。學(xué)生在觀察能力、思維能力、語(yǔ)言表達(dá)能力方面都有了較好的提高，有著強(qiáng)烈的好奇心與動(dòng)手操作的能力。他們喜歡在自己的探索中獲取知識(shí)，喜歡在玩中學(xué)，喜歡在做中學(xué)，喜歡在想中學(xué)，喜歡在用中學(xué)。三、Teaching ContentUnit4 At the farm B .
