2、2系列的教學(xué)案。要求太泛，可以在精練一點(diǎn)2.復(fù)習(xí)導(dǎo)學(xué)：(1)形容詞和副詞的原級。句中通常有so, very, too，asas這些標(biāo)志詞。例：Im very tired.He jumps so high.I write as carefully as Helen.(2)形容詞和副詞比較級的定義。 形容詞比較級：用于人或物兩者進(jìn)行比較時(shí)，表示“更”。句中通常有than, much, a little, A or B這些關(guān)鍵詞句。 副詞比較級：用于動(dòng)作的比較，通常與動(dòng)詞共同使用，表示“更”。副詞和形容詞可以合并在一起進(jìn)行比較區(qū)分(3)形容詞與副詞比較級的構(gòu)成規(guī)律：構(gòu)成法原級比較級一般在形容詞或副詞

3、后加ertall，hightaller, higher結(jié)尾有e的直接加rnice, latenicer, later重讀閉音節(jié)單詞，需要雙寫最后的輔音字母，再加-erbig, thin, fat, hot, redbigger, thinner, fatter, hotter, redder以輔音字母加y結(jié)尾的詞，變y為i，再加-erheavy, early, happy, busyheavier, earlier, happier, busier有些形容詞和副詞的比較級是不規(guī)則的，如: good/ well -better, far-farther, many/ much-more (4)形

4、容詞比較級句子的結(jié)構(gòu)是：句型的列舉不要用公式的形式來表達(dá)+be+形容詞比較級+than+例：Mike is shorter than her.My pencils are longer than theirs.(5)副詞比較級句子結(jié)構(gòu)（以一般現(xiàn)在時(shí)為例）：+行為動(dòng)詞(s/es)+副詞比較級+than+ 例如：肯定句：Helen sings better than Mike. The girls sing better than the boys.否定句：Helen doesn't sing better than Mike. The girls don't sing bette

5、r than the boys. 一般疑問句：Does Helen sing better than Mike? Do the girls sing better than the boys?(6)形容詞比較級與副詞比較級的區(qū)分：比較對象不同：形容詞比較級用于比較人或物，副詞比較級用于比較動(dòng)作。動(dòng)詞搭配不同：形容詞比較級搭配be動(dòng)詞，My mother is taller than my sister. 副詞比較級搭配行為動(dòng)詞，My mother runs faster than my sister.(7) tall 指身高，high 指動(dòng)作做得高 big, small指體積的大小，old,

6、young指年齡的大小。 good 修飾名詞，指事物好，well 修飾動(dòng)詞，指動(dòng)作做得好。在這兩類詞的列舉中要在簡單省略點(diǎn)3.預(yù)習(xí)自測：一、 句型轉(zhuǎn)換。1. Tom is taller than his classmates. (同義句轉(zhuǎn)換) His classmates _ _ _ Tom.2.
