形容詞、副詞的比較級(jí)和最高級(jí)的構(gòu)成規(guī)則
1.一般單音節(jié)詞和少數(shù)以-er,-ow結(jié)尾的雙音節(jié)詞,比較級(jí)在后面加-er,最高級(jí)在后面加-est;
(1)單音節(jié)詞
如:small→smaller→smallest short→shorter→shortest
tall→taller→tallest great→greater→greatest
(2)雙音節(jié)詞
如:clever→cleverer→cleverest narrow→narrower→narrowest
2.以不發(fā)音e結(jié)尾的單音節(jié)詞,比較在原級(jí)后加-r,最高級(jí)在原級(jí)后加-st;
如:large→larger→largest nice→nicer→nicest able→abler→ablest
3.在重讀閉音節(jié)(即:輔音+元音+輔音)中,先雙寫(xiě)末尾的輔音字母,比較級(jí)加-er,最高級(jí)加-est;
如:big→bigger→biggest hot→hotter→hottest fat→fatter→fattest
4.以“輔音字母+y”結(jié)尾的雙音節(jié)詞, 把y改為i,比較級(jí)加-er,最高級(jí)加-est;
如:easy→easier→easiest heavy→heavier→heaviest
busy→busier→busiest happy→happier→happiest
5.其他雙音節(jié)詞和多音節(jié)詞,比較級(jí)在前面加more,最高級(jí)在前面加most;
如:beautiful→more beautiful→most beautiful
different→more different→most different
easily→more easily→most easily
注意:(1)形容詞最高級(jí)前通常必須用定冠詞 the,副詞最高級(jí)前可不用。
例句: The Sahara is the biggest desert in the world.
(2) 形容詞most前面沒(méi)有the,不表示最高級(jí)的含義,只表示“非?!?
It is a most important problem.
=It is a very important problem.
6.有少數(shù)形容詞、副詞的比較級(jí)和最高級(jí)是不規(guī)則的,必須熟記。
如:good→better→best well→better→best
bad→worse→worst ill→worse→worst
old→older/elder→oldest/eldest
many/much→more→most little→less→least
far →further/farther→ furthest/farthest
