3、較級前面一般用much, even, a little修飾，表示程度；其中even, much 只能修飾比較級。形容詞、副詞的比較級和最高級的句子構(gòu)成：1.比較級：表達“A大于B” 物體A + am / are / is + 形容詞比較級 + than + 物體B. I am taller than you. Pasta is more delicious than pizza. 物體A + 行為動詞 + 副詞比較級 + than + 物體B. Mary runs faster than Sam . He studies better than me.表達“A和B一樣”，用asas的結(jié)構(gòu)。 A
