（1）學(xué)生能夠盡可能多地使用本板塊的核心詞匯和學(xué)生用書

（2）學(xué)生能夠正確使用形容詞、副詞的比較級(jí)和最高級(jí)。一、教學(xué)要求

1.學(xué)生在語篇學(xué)習(xí)過程中已經(jīng)接觸過一些規(guī)則形容詞和副詞變比較級(jí)和最高級(jí)（+er,+est）以及不規(guī)則變化，但在將語言感知轉(zhuǎn)化為系統(tǒng)的語法知識(shí)方面還需加強(qiáng)?？勺寣W(xué)生在情景運(yùn)用練習(xí)中將語言感知轉(zhuǎn)化為系統(tǒng)的語法學(xué)習(xí)。2.在變化規(guī)則的學(xué)習(xí)中，雙寫、變y為i等規(guī)則易遺忘，造成變形錯(cuò)誤，且不規(guī)則變化與規(guī)則變化相互干擾，記憶和運(yùn)用都易出錯(cuò)。構(gòu)建句子時(shí)，學(xué)生對(duì)than和the的使用以及比較范圍的表達(dá)較為生疏，容易出錯(cuò)?？勺寣W(xué)生制作規(guī)則和不規(guī)則變化的對(duì)比卡片，將形容詞、副詞變比較級(jí)和最高級(jí)的規(guī)則（雙寫、變y為i等

）及不規(guī)則形式清晰羅列，便于學(xué)生在日常學(xué)習(xí)中強(qiáng)化記憶。二、學(xué)情分析

以重讀閉音節(jié)結(jié)尾的詞，如末尾只有一個(gè)輔音字母，應(yīng)先雙寫該字母，再加-er,estbigfatbiggerfatterbiggestfattest以“輔音字母+y”結(jié)尾的詞，先把y變成i，再加-er,esteasyfunnyeasierfunniereasiestfunnest部分雙音節(jié)和多音節(jié)單詞在單詞前加more,mostinterestingcomfortablymoreinteresting
