形容詞和副詞的比較級和最高級形容詞：是修飾名詞（人或事物），表示名詞的性質，特征或屬性一種詞類。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.

一、形容詞和副詞的概念

①形容詞作定語一般放在被修飾的名詞之前。如:

anew

book,two

bigtrees

等。二、形容詞和副詞的用法②形容詞放在系動詞be、look、get、keep、turn、feel、become、seem、grow、smell等之后。如:1.I

am

short.2.Shelooks

fine.3.They

turn

green.③如果形容詞修飾不定代詞something,anything,everything,nothing等時，要放在不定代詞后面。如:somethinginterestingnothingnew④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.Iamverybusy.（修飾形容詞）3.Herunstooquickly.（修飾副詞）4.Weplayhappily.（修飾動詞）⑤通常在形容詞后加-ly變成副詞。slow→______real→______usual→______careful→______easy→______happy→______heavy→______angry→______slowlyusuallyeasilyheavilyreallycarefullyhappilyangrilybigbigger

原級、比較級、最高級smallsmallersmallest構成方法原級比較級最高級單音節詞和少數多音節詞一般在詞尾加-er/?/或-est/ist/coldcoldercoldestfastfasterfastest以字母e結尾的形容詞，加-r或-stnicenicernicestlargelargerlargest重讀閉音節詞只有一個輔音字母時，應先雙寫輔音字母；再加-es或-estbigbiggerbiggesthothotterhottest以“輔音字母+y”結尾的雙音節詞，先改“+y”結尾的雙音節詞，先改“y”為“i”,再加-er或-esteasyeasiereasiestearlyearlierearliest多音節詞和部分雙音節詞在詞前加more或mosttiredmoretiredmosttiredbeautifulmorebeautifulmostbeautiful單音節和少數多音節的形容詞和副詞的比較級和最高級的構成分規則和不規則。變化如下：請你牢記：一，要雙寫再加-er,-est的詞有哪些？hotbigfatthinredwetsadglad…二.不規則變化的詞有哪些？原級比較級最高級good/wellbetterbestbad/ill/badlyworseworstmany/muchmoremostlittlelessleastoldolderoldesteldereldestfarfartherfarthestfurtherfurthestNotes:類似slowly,quickly這樣的雙音節詞，雖然也是輔音字母加y結尾，但這里的-ly是表示副詞的后綴，因此比較級和最高級的構成是在單詞前加more和most。2.強調程度時，形容詞和副詞前可加上too,very,so,quite等。比較級前則要加上much,even,alittle,alot,still,abit等詞(組)，表示程度。3.

farther常指時間、距離上的遠。further常用于引伸和抽象的意義，表示“進一步，更深刻，更深入等”。4.older表示年齡大小或年代的久遠，elder表示兄弟姐妹之間的長幼關系。沒有比較級和最高級的詞含有絕對概念的有形容詞和副詞：absolute,entire,whole,total,perfect,excellent,thorough,complete,wonderfulimportant

①在含有連詞than的比較級中，前后的比較對象必須是同一范疇，即同類事物之間的比較。

②在比較級前面使用much，表示程度“強得多”。如：Awatermelonismuchbiggerthananapple.

③very,quite一般只能修飾原級，不能修飾比較級。注意：2．“比較級+and+比較級”或“moreandmore+原級”表示“越來越……”
