PAGEPAGE4一、比較級(jí)和最高級(jí)的講解變化規(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→smallestshort→shorter→shortesttall→taller→tallestgreat→greater→greatest（2）雙音節(jié)詞如：clever→cleverer→cleverestnarrow→narrower→narrowest2．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→largestnice→nicer→nicestable→abler→ablest3．在重讀閉音節(jié)（即：輔音＋元音＋輔音）中，先雙寫末尾的輔音字母，比較級(jí)加-er，最高級(jí)加-est；如：big→bigger→biggesthot→hotter→hottestfat→fatter→fattest4．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→easiestheavy→heavier→heaviestbusy→busier→busiesthappy→happier→happiest5．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→morebeautiful→mostbeautifuldifferent→moredifferent→mostdifferenteasily→moreeasily→mosteasily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：TheSaharaisthebiggestdesertintheworld.（2）形容詞most前面沒(méi)有the，不表示最高級(jí)的含義，只表示"非常"。Itisamostimportantproblem.=Itisaveryimportantproblem.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→bestwell→better→bestbad→worse→worstill→worse→worstold→older/elder→oldest/eldestmany/much→more→mostlittle→less→leastfar→further/farther→furthest/farthest一、寫出下列形容詞和副詞的比較級(jí)形式。1.long_______2.tidy______3.hot_____________4.large________5.thin_________6.good_____________7.bad_________8.little_________9.sincere____________10.much_______11.early_________12.fast_____________13.hard_______14.difficult_________15.badly____________16.far_________17.carefully_________18.instructive________19.easily______20.often____________二、形容詞、副詞的比較級(jí)和最高級(jí)的用法1．“A+be+形容詞比較級(jí)+than+B”意思為“A比B更……”。如：Thistreeistallerthanthatone.這棵樹(shù)比那棵樹(shù)高。注意：①在含有連詞than的比較級(jí)中，前后的比較對(duì)象必須是同一范疇，即同類事物之間的比較。②在比較級(jí)前面使用much，表示程度程度“強(qiáng)得多”。如：Awatermelonismuchbiggerthananapple.③very,quite一般只能修飾原級(jí)，不能修飾比較級(jí)。Thisismuchthebest.b.序數(shù)詞通常只修飾最高級(jí)。Africaisthesecondlargestcontinent.10.要避免重復(fù)使用比較級(jí)。(錯(cuò))Heismoreclevererthanhisbrother.(對(duì))Heismorecleverthanhisbrother.(對(duì))Heisclevererthanhisbrother.11.要避免將主語(yǔ)含在比較對(duì)象中。(錯(cuò))ChinaislargerthatanycountryinAsia.(對(duì))ChinaislargerthananyothercountryinAsia.12.要注意對(duì)應(yīng)句型，遵循前一致的原則。ThepopulationofShanghaiislargerthanthatofBeijing.Itiseasiertomakeaplanthantocarryitout.13.要注意冠詞的使用，后有名詞的時(shí)候，前面才有可能有名詞。比較：Whichislarger,CanadaorAustralia?Whichisthelargercountry,CanadaorAustralia?Sheistallerthanhertwosisters.Sheisthetallerofthetwosisters.二、根據(jù)句意，用所括號(hào)內(nèi)所級(jí)形容詞的比較等級(jí)形式填空：1.Bobis_________(young)thanFredbut___________(tall)thanFred.2.Yingtianisnotas___________(tall)asYongxian.3.Almostallthestudents'facesarethesamebutLiDeminglooks_______(fat)thanbefore.4.Whichis_________(heavy),ahenorachicken?5.--How_________(tall)isSally?--She's1.55metres________(tall).WhataboutXiaoling?--She'sonly1.40metres________(tall).Sheismuch_______(short)thanSally.Sheisalsothe_______(short)girlintheclass.6.Heis______(bad)atlearningmaths.Heismuch_______(bad)atChineseandheisthe_________(bad)atEnglish.7.AnniesaysSallyisthe________(kind)personintheworld.8.Heisoneofthe_________(friendly)peopleintheclass,Ithink.9.Adictionaryismuch(expensive)thanastory-book.10.Anorangeiaalittle______(big)thananapple,butmuch________(small)thanawatermelon.11.TheChangjiangRiveristhe_______(long)riverinChina.
