形容詞和副詞的比較級和最高級Unit3-4形容詞：是修飾名詞（人或事物），表示名詞的性質、特征或屬性的一種詞類。它在句中作定語、表語和賓語補足語。副詞：用來修飾動詞、形容詞及其他副詞的詞叫副詞。副詞在句中多作狀語.

somewhereinterestingsomethingelse④副詞放在所修飾的動詞之后，形容詞和副詞之前。如果前面是行為動詞，則后面用副詞。如:1.Sheworkshard.（修飾動詞）

2.Iam

verybusy.（修飾形容詞）

3.Herunstoo

quickly.（修飾副詞）

一、構成的規(guī)則變化:1、單音節(jié)詞和少數(shù)雙音節(jié)詞一般在詞尾加-

er或-este.g.

cold–colder–coldestnice—nicer–nicest2、重讀閉音節(jié)詞末尾只有一個輔音字母時,先雙寫這個輔音字母,再加-er或-est。

big–bigger–biggestthin–thinner–thinnest3、以“輔音字母+y”結尾的雙音節(jié)詞，先改y為i,再加-er或-est。

4、多音節(jié)詞和部分雙音節(jié)詞在詞前加more或most。
