比较级、最高级的构成规则及专项练习 1.一般单音节词和少数以-er,-ow结尾的双音节词,比较级在后面加-er,最高级在后面加-est; (1)单音节词 如:small→smaller→smallest short→shorter→shortest tall→taller→tallest great→greater→greatest (2)双音节词 如:clever→cleverer→cleverest narrow→narrower→narrowest 2.以不发音e结尾的单音节词,比较级在原级后加-r,最高级在原级后加-st; 如:large→larger→largest nice→nicer→nicest able→abler→ablest 3.在重读闭音节(即:辅音+元音+辅音)中,先双写末尾的辅音字母,比较级加-er,最高级加-est; 如:big→bigger→biggest hot→hotter→hottest fat→fatter→fattest 4.以“辅音字母+y”结尾的双音节词, 把y改为i,比较级加-er,最高级加-est; 如:easy→easier→easiest heavy→heavier→heaviest busy→busier→busiest happy→happier→happiest 5.其他双音节词和多音节词(一个元音为一个音节),比较级在前面加more,最高级在前面加most; 如:beautiful→more beautiful→most beautiful different→more different→most different tired→more tired→most tired (很重要,也很特殊) 注意:(1)形容词最高级前通常必须用定冠词 the,副词最高级前可不用。 例句: The Sahara is the biggest desert in the world. (2) 形容词most前面没有the,不表示最高级的含义,只表示"非常"。 It is a most important problem. =It is a very important problem. 6.有少数形容词、副词的比较级和最高级是不规则的,必须熟记。 如:good(well)--better--best bad(ill)--worse--worst Old--older/elder--oldest/eldest many/much—more--most Little—less--least far --further/farther-- furthest/farthest 构成方法 : (1)一半在词尾加-er或-est (2)以e结尾的词,加-r或-st (3)重读闭音节词词尾只有一个辅音字母时,先双写辅音字母,再加-er-est (4)以“辅音字母+y”结尾的双音节词,先把“y”改为“i”,再加-er或-est (5)在此前面加more或most 一、请写出下列形容词的比较级和最高级。 big ______ ______ small ______ ________ new ______ ________ tall ______ ______ short______ ________ old______ ________ weak ______ ______ strong ______ ______ fat______ ________ 1 本文来源:https://www.wddqw.com/doc/ed376682960590c69ec3765f.html
