形容詞變副詞的規(guī)則：
1.一般情況下直接加“l(fā)y”,如quick---quickly 2.以“y”結(jié)尾的,先將“y”改成“i”,再加“l(fā)y”,如happy---happily
少數(shù)以e結(jié)尾的形容詞,要去掉e再加-ly.例如：true-truly等.
但絕大多數(shù)以e結(jié)尾的形容詞仍然直接加-ly.例如：polite-politely,wide-widely等.
形容詞變副詞通常是加ly,其變化有規(guī)律可循,請(qǐng)記住以下口訣：
一般直接加,“元e”去e加,“輔y”改i加,“l(fā)e”結(jié)尾e改y.
分別舉例如下：
quick—quickly,
true—truly,
happy—happily,
possible—possibly.
另外：
一、在形容詞詞尾直接加-ly.如:real-really; helpful-helpfully; careful-carefully; hopeful-hopefully; slow-slowly; quick-quickly; quiet-quietly
二、以輔音字母加y結(jié)尾的形容詞要變y為i,然后再加-ly.如:busy-busily; angry-angrily; easy-easily
三、某些以輔音字母加不發(fā)音的字母e結(jié)尾和以-ue結(jié)尾的形容詞要先去掉e,然后再加-y或-ly.如:terrible-terribly; true-truly; gentle-gently
另外,副詞還可以由形容詞加前綴a-得來(lái),如:loud (adj.)-aloud (adv.)
此外,部分名詞加后綴也可變成副詞,如:part-partly.
例句:It is partly her fault.有部分是她的錯(cuò).
需注意:friendly; motherly; lovely等詞是形容詞而非副詞.
再看轉(zhuǎn)化副詞.在英語(yǔ)中,有些詞既可以作形容詞,又可以作副詞,如early,much,fast,little,wide,loud等.由于這類詞詞性雖不同,但詞形卻一樣,這就需要大家學(xué)會(huì)在特定語(yǔ)境中判斷它們各自的詞性.例句:Thank you very much.(adv.) 多謝.There is much water in the river.(adj.) 河里有很多水.The music is too loud.Please turn it down.(adj.) 音樂(lè)聲太大,請(qǐng)調(diào)低點(diǎn).He speaks loud enough.So everyone in the room can hear what he said.(adv.) 他說(shuō)話的聲音很大,所以房間里每個(gè)人都能聽(tīng)到他的話.
另外,還有一類副詞和形容詞詞義相同,但拼寫(xiě)卻不同,如well和good.例句He speaks good English.他講一口流利的英語(yǔ).He speaks English well.他英語(yǔ)講得不錯(cuò).
