/klɪərə/、clearest

/klɪərɪst/。如果原级词末的发音为/ŋ/，加er和est时，/ŋ/音后得加上/g/音，如long/lɒŋ/、longer

/lɒŋgə(r)/、longest

/lɒŋgɪst/。形容词比较级常见用法如下：1通常情况下，我们用“比较级+than”来引出比较的第二部分。①Thispictureismorebeautiful

thanthatone.这幅画比那幅画更漂亮。②

Thewhitecatisfatterthan

theblackcat.白猫比黑猫胖。我们常用“Which/Who...+

比较级，...

or...?”的句型表示在两者中选择。①

Whichpictureismorebeautiful,thisoneorthatone?这幅画和那幅画，哪个更漂亮？②

Whoisyounger,JohnorJimmy?约翰和吉米，谁更年轻？口诀比较级要变化，一般词尾加-er。词尾若有哑音e，直接加r就可以。重读闭音节，单个辅音字母要双写。辅音字母加y，要把y改i。最高级加-est，前面加the莫忘记。形容词若是多音节，只把more，most前面写Completethetablewiththecorrectcomparativeandsuperlativeadjectives.AdjectiveComparativeSuperlativeAdjectiveComparativeSuperlativefunnyprettyclosebrightbeautifulinterestingkindsadslimwonderfuldifficultheavysmartgoodcutebadPracticeAdjectiveComparativeSuperlativeAdjectiveComparativeSuperlativefunnyfunnierfunniestprettyprettierprettiestclosecloserclosestbrightbrighterbrightestbeautifulmorebeautifulthemostbeautifulinterestingmoreinterestingthemostinterestingkindkinderkindestsadsaddersaddestslimslimmerslimmestwonderfulmorewonderfulthemostwonderfuldifficultmoredifficultthemostdifficultheavyheavierheaviestsmartsmartersmartestgoodbetterbestcutecutercutestbadworseworstChecktheanswers.注意：构成形容词比较级和最高级的er和est，自成一个音节，读作/ə(r)/和/ɪst/。如果原级词末为不发音的字母r，加er和est时，r要发/r/音，如clear/klɪə(r)/、clearer/ˈklɪərə(r)/、clearest/ˈklɪərɪst/。如果原级词末的发音为/ŋ/，加er和est时，/ŋ/音后得加上/ɡ/音，如long/lɒŋ/、longer/ˈlɒŋɡə(r)/、longest/ˈlɒŋɡɪst/。形容词比较级、最高级的常见用法1.A+be+比较级+than+B.e.g.TinaismorebeautifulthanBetty.
