一、形容詞、副詞的比較級和最高階的構成規則
1.一般單音節詞和少數以-er, -ow結尾的雙音節詞,比較級在後面加-er,最高階在後面加-est;
(1)單音節詞
如:small→ smaller- * smallest short- + shorter- + shortest
tall→taller→tallest great→greater- + greatest
(2)雙音節詞
如:clever- +cleverer- *cleverest narrow- +narrower - * narrowest
2.以不發音e結尾的單音節詞,比較在原級後加-r,最高階在原級後加-st;
如:large- + larger- + largest nice- +nicer - *nicest able- +abler- +ablest
3.在重讀閉音節(即:子音+母音+子音)中,先雙寫末尾的子音字母,比較級加-er,最高階加-est;
如:big→ bigger→biggest hot -→hotter- + hottest fat→ fatter→fattest
4.以子音字母+y"結尾的雙音節詞,把y改為i,比較級加-er,最高階加-est
如:easy- +easier- + easiest heavy→heavier - + heaviest
busy→busier- + busiest happy→happier - +happiest
5.其他雙音節詞和多音節詞,比較級在前面加more,最高階在前面加most,如:beautiful→more beautiful- →most beautiful

easily- * more easi ly→most easily
注意:(1)形容詞最高階前通常必須用定冠詞the, 副詞最高階前可不用。例句:The Sahara is the biggest desert in the world.
(2) 形容詞most前面沒有the, 不表示最高階的含義,只表示"非常"。It is a most important problem.
=It is a very important problem.
6.有少數形容詞、副詞的比較級和最高階是不規則的,必須熟記。
如:good→better- +best well→better- →best
bad- *worse- tworst ill- + worse→worst
