形容詞和副詞有三個比較等級：
①原級；②比較級；③最高級。
兩者之間比較用比較級；
三者或者三者以上進行比較用最高級。
形容詞和副詞比較等級的構成
1.什么是形容詞的原級？
表示修飾兩種東西的程度是一樣的,用as… as表示原級， 譯為“和……一樣”。
2.什么是形容詞的比較級？
表示兩者相比，一個比另一個更……，有比較級的 句中通常有than,且僅限于兩者比較。

不規則變化
比較級規則變化口訣
比較級要變化，一般詞尾加 er。
詞尾若有啞音e，直接加r就可以。
輔音字母若加y, 記得變y為i。
一輔重讀閉音節，末尾字母要雙寫。
多、雙音節有規律，詞前加more就可以。
比較級的用法
1）主語(‘A’)+謂語動詞+形容詞/副詞比較級+than+主語(‘B’)+ …
e.g. A modern train is faster than a car.
This book didn’t cost me more than that one.
2）在形容詞比較級前還可用much、even、 still、far、
a little等來修飾，表示“……的多”，“甚至……”,
“更……”, “……一些”。
e.g. He is much more serious than his brother.
This book is even more useful than that one.
3）“比較級＋and＋比較級”意為“越來越……” ，
多音節比較級用“more and more＋形容詞原級”形式。
e.g. It is raining harder and harder.
Chinese is becoming more and more popular.
4）“Which / Who is + 比較級… ”比較A、B兩事物, 問其中哪一個較……時用此句型。
e.g. Which T-shirt is nicer, this one or that one
Who is more active, Mary or Kate
5）the+比較級...，the+比較級... 表示“越……, 越……”。
e.g. The more, the better.
The harder you work,the better grades you’ll get.
