形容詞要用比較級的形式，形容詞比較級之后要用than引出比較的對象。單音節(jié)和少數(shù)雙音節(jié)單詞構(gòu)成方法原級比較級一般在詞尾加-ertall,long,short,

old,small以字母e結(jié)尾的形容詞直接加-rnice,fine,large以重讀閉音節(jié)結(jié)尾的形容詞，如末尾只有一個輔音字母，應(yīng)先雙寫該字母，再加-erbig,hot,thin以“輔音字母+y”結(jié)尾的形容詞，先把y變成i，再加-erbusy,easy,earlytaller,longer,shorter,older,smallernicer,finer,largerbigger,hotter,

thinnerbusier,easier,

earlier注意：表示比較時，原來的句子結(jié)構(gòu)并沒有改變，只是將形容詞變成比較級的形式，然后在后面用than引出所比較的對象。如：原來的句式是The

YangtzeRiveris

long，在與另一條河進(jìn)行比較時，則只將long變成longer，后面加上“than+比較的對象(如theYellowRiver)”即可。如果基本句式是Summer

is

a

hotseason，在與其他季節(jié)比較時，只需將形容詞變成比較級的形式，其他結(jié)構(gòu)不變，即Summer

is

a

hotter

season，然后接“than+比較的對象”即可。例如:Summerisahotterseasonthanspring.
