形容詞變副詞通常是加ly,其變化有規(guī)律可循,請記住以下口訣:

一般直接加,―元(e)去e加,―輔(y)改i加,le結(jié)尾e改y。

分別舉例如下:quick---quickly; true---truly; happy---happily; possible----possibly

具體規(guī)則如下:

1) .一般情況下直接加―ly,如:

quick---quickly; polite---politely; sad---sadly; immediate---immediately; recent---recently

2). 少數(shù)以e結(jié)尾的形容詞,要去掉e再加-ly。如:

true-truly; due-duly

絕大多數(shù)輔音字母加e結(jié)尾的形容詞直接加-ly。

如:polite-politely; wide-widely; wise-wisely; nice-nicely

3). 以―個y結(jié)尾的,且讀音為 / i /, 先將―y改成―i,再加―ly,如:

happy---happily; heavy---heavily; angry---angrily; busy---busily

但是如果讀音為 / ai /, 直接加ly,如:

dry-dryly; sly-slyly; shy---shyly

4).以ic 結(jié)尾的詞,加ally,如:

economic---economically; basic---basically; scientific---scientifically; automatic---automatically; energetic---energetically

5).以輔音字母加le結(jié)尾時,去e加y,如:

simple---simply; considerable---considerably; terrible---terribly; gentle---gently; possible---possibly; probable---probably; incredible---incredibly

元音字母加le時加 ly,如:sole-solely。但是whole-wholly例外。

6). 以-ll結(jié)尾時,只須加 –y,如:

dull---dully; shrill---shrilly

需注意: 有些以ly結(jié)尾的詞是形容詞而非副詞。如:

friendly people; motherly care; lovely dog; monthly exam; heavenly peace; a manly sport
