A Poem
Good, better, best,
Never let it rest,
And till good is better,
Better is best !
好，更好，最好，
永不停歇，
直到好變為更好，
那么更好就是最好！
大多數形容詞有三個等級：原級、比較級和最高級。
原級指形容詞未經比較變化的初始形態。
當我們將兩個對象進行比較時，我們要用形容詞的比較級，表示“較……” “更……一些” “比……更……”。
當被比較的對象是三個或三個以上時，我們會用形容詞的最高級，表示“最……”，最高級前通常要加定冠詞 the。
Activity 1
Know how to form adjectives’ comparatives and superlatives
Look at the words and try to work out the rules of the formation of the adjectives’ comparatives and superlatives.
great greater greatest
tall taller tallest
small smaller smallest
① 大多數詞后加er變成比較級，加est變成最高級。
nice nicer nicest
fine finer finest
large larger largest
② 以字母e結尾的詞只加r或st變成比較級或最高級。
Look at the words and try to work out the rules of the formation of the adjectives’ comparatives and superlatives.
slim slimmer slimmest
big bigger biggest
red redder reddest
③ 以一個輔音字母結尾的重讀閉音節詞，雙寫最后一個輔音字母，再加er或est。
Look at the words and try to work out the rules of the formation of the adjectives’ comparatives and superlatives.
pretty prettier prettiest
easy easier easiest
busy busier busiest
④ 以輔音字母加y結尾的詞先去掉y，再加ier或iest。
Look at the words and try to work out the rules of the formation of the adjectives’ comparatives and superlatives.
beautiful more beautiful most beautiful
important more important most important
careful more careful most careful
popular more popular most popular
⑤ 多音節詞和部分雙音節詞應在其前加more變成比較級，加most變成最高級。
Look at the words and try to work out the rules of the formation of the adjectives’ comparatives and superlatives.
注意：
構成形容詞比較級和最高級的er和est，自成一個音節，讀作/ (r)/ 和/ st/。如果原級詞末為不發音的字母 r，加er和est 時，r 要發/r/ 音，如clear /kl (r)/、clearer / kl r (r)/、clearest / kl r st/。如果原級詞末的發音為/ /，加er 和est 時，/ /音后得加上/ɡ/音，如 long /l /、longer / l ɡ (r)/、longest / l ɡ st/。
