二、語言知識歸納：形容詞比較級的構成與用法，比較級是比較等級語言點的下屬分枝。

（一）比較等級的概念

1. 形容詞和副詞的比較等級分為原級、比較級和最高級三種。

2. 隻描繪性形容詞和副詞才有比較等級。

3. 形容詞和副詞比較級和最高級的的構成分為兩種情況：

1）多數雙音節和所有多音節形容詞或副詞加more -, most -；

2）單音節及少數以-er, -ow, -y結尾的雙音節形容詞或副詞 加-(e)r, -(e)st。

（二）比較等級的構成

1．形容詞和副詞的原級就是它們的原形，除它們的一般用法外，還用于as…as, (not) as / so…as句型，如：

This building looks not as / so high as that one. (so…as隻用于否定句)

Mr Sun speaks English as fluently as you. (as…as既能用于肯定句，又能用于否定句)

2. 加more, most構成比較級或最高級的形容詞和副詞詞根無變化；如：

sudden-more sudden-most sudden, difficult-more difficult-most difficult,…

3. 加-(e)r, -(e)st構成比較級或最高級的形容詞和副詞的詞根變化規則如下：
