/kl??r?/、clearest

/kl??r?st/。如果原級(jí)詞末的發(fā)音為/?/，加er和est時(shí)，/?/音后得加上/g/音，如long/l??/、longer

/l??g?(r)/、longest

/l??g?st/。形容詞比較級(jí)常見用法如下：1通常情況下，我們用“比較級(jí)+than”來引出比較的第二部分。①Thispictureismorebeautiful

thanthatone.這幅畫比那幅畫更漂亮。②

Thewhitecatisfatterthan

theblackcat.白貓比黑貓胖。我們常用“Which/Who...+

比較級(jí)，...

or...?”的句型表示在兩者中選擇。①

Whichpictureismorebeautiful,thisoneorthatone?這幅畫和那幅畫，哪個(gè)更漂亮？②

Whoisyounger,JohnorJimmy?約翰和吉米，誰更年輕？口訣比較級(jí)要變化，一般詞尾加-er。詞尾若有啞音e，直接加r就可以。重讀閉音節(jié)，單個(gè)輔音字母要雙寫。輔音字母加y，要把y改i。最高級(jí)加-est，前面加the莫忘記。形容詞若是多音節(jié)，只把more，most前面寫Completethetablewiththecorrectcomparativeandsuperlativeadjectives.AdjectiveComparativeSuperlativeAdjectiveComparativeSuperlativefunnyprettyclosebrightbeautifulinterestingkindsadslimwonderfuldifficultheavysmartgoodcutebadPracticeAdjectiveComparativeSuperlativeAdjectiveComparativeSuperlativefunnyfunnierfunniestprettyprettierprettiestclosecloserclosestbrightbrighterbrightestbeautifulmorebeautifulthemostbeautifulinterestingmoreinterestingthemostinterestingkindkinderkindestsadsaddersaddestslimslimmerslimmestwonderfulmorewonderfulthemostwonderfuldifficultmoredifficultthemostdifficultheavyheavierheaviestsmartsmartersmartestgoodbetterbestcutecutercutestbadworseworstChecktheanswers.注意：構(gòu)成形容詞比較級(jí)和最高級(jí)的er和est，自成一個(gè)音節(jié)，讀作/?(r)/和/?st/。如果原級(jí)詞末為不發(fā)音的字母r，加er和est時(shí)，r要發(fā)/r/音，如clear/kl??(r)/、clearer/?kl??r?(r)/、clearest/?kl??r?st/。如果原級(jí)詞末的發(fā)音為/?/，加er和est時(shí)，/?/音后得加上/ɡ/音，如long/l??/、longer/?l??ɡ?(r)/、longest/?l??ɡ?st/。形容詞比較級(jí)、最高級(jí)的常見用法1.A+be+比較級(jí)+than+B.e.g.TinaismorebeautifulthanBetty.
