英语形容词变副词的不规则变化形容词变副词的规则:1.一般情况下直接加“ly”,如quick---quickly2.以“y”结尾的,先将“y”改成“i”,再加“ly”,如happy---happily少数以e结尾的形容词,要去掉e再加-ly。例如:true-truly等。但绝大多数以e结尾的形容词仍然直接加-ly。例如:polite-politely,wide-widely等。形容词变副词通常是加ly,其变化有规律可循,请记住以下口诀:一般直接加,“元e”去e加,“辅y”改i加,“le”结尾e改y。分别举例如下:quick—quickly,true—truly,happy—happily,possible—possibly.另外:一、在形容词词尾直接加-ly。如:real-really;helpful-helpfully;careful-carefully;hopeful-hopefully;slow-slowly;quick-quickly;quiet-quietly二、以辅音字母加y结尾的形容词要变y为i,然后再加-ly。如:busy-busily;angry-angrily;easy-easily三、某些以辅音字母加不发音的字母e结尾和以-ue结尾的形容词要先去掉e,然后再加-y或-ly。如:terrible-terribly;true-truly;gentle-gently另外,副词还可以由形容词加前缀a-得来,如:loud(adj.)-aloud(adv.)此外,部分名词加后缀也可变成副词,如:part-partly。例句:Itispartlyherfault.有部分是她的错。需注意:friendly;motherly;lovely等词是形容词而非副词。再看转化副词。在英语中,有些词既可以作形容词,又可以作副词,如early,much,fast,little,wide,loud等。由于这类词词性虽不同,但词形却一样,这就需要大家学会在特定语境中判断它们各自的词性。例句:Thankyouverymuch.(adv.)多谢。Thereismuchwaterintheriver.(adj.)河里有很多水。Themusicistooloud.Pleaseturnitdown.(adj.)音乐声太大,请调低点。Hespeaksloudenough.Soeveryoneintheroomcanhearwhathesaid.(adv.)他说话的声音很大,所以房间里每个人都能听到他的话。另外,还有一类副词和形容词词义相同,但拼写却不同,如well和good。例句HespeaksgoodEnglish.他讲一口流利的英语。HespeaksEnglishwell.他英语讲得不错。多音节y结尾的词将y改为i后加lyeasy-easilyhappy-happilyheavy-heavily单音节y结尾的词直接加lygay-gayly(gaily)sly-slyly(slily)以ve结尾的词去e加lytrue-truly以le结尾的词去e加ygentle-gentlypossible-possibly其他以e结尾的词一律加lynice-nicelywise-wiselypolite-politely以ll结尾的词只加yfull-fully以ic结尾的词加allyautomatic-automaticallyenergetic-energetically其他形容词均加lycareful-carefullyglad-gladly
