一般情況下，單音節詞和個別雙音節詞直接在詞尾加-ertalltaller

以不發音的字母e結尾的單音節詞和少數雙音節詞只在詞尾加-rnicenicer形容詞的比較級構成方法原級比較級

以重讀閉音節結尾且詞尾只有一個輔音字母時，雙寫結尾的輔音字母，再加-erbigbigger

以“輔音字母＋y”結尾的雙音節詞，變y為i，再加-erbusybusier

其他雙音節詞和多音節詞，在前面加more來構成比較級important/easilymoreimportant/moreeasily

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。重讀閉音節，單個輔音字母要雙寫。輔音字母加上y，要把y來改為i。比較級規則變化助記口訣2.不規則變化原級比較級good/wellbetterbad/badly/illworseoldolder/eldermuch/manymorelittlelessfarfarther/further活動小結通過以上的活動，我們可以知道比較級的構成：1.規則變化——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。重讀閉音節，單個輔音字母要雙寫。輔音字母加上y，要把y來改為i。2.不規則變化探究二Thistreeis_____thanthattree.Sheis______thanbefore.tallerthinner1.A+be+形容詞比較級+than+B.
