爱华网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;pssible-possibly
具体规则如下：
1.一般情况下直接加“ly”，如：
quick-quickly; polite-politely; sad-sadly;imediate-immediately; recent-recently
2.少数以e结尾的形容词，要去掉e再加-ly。如：true-truly;due-duly
绝大多数辅音字母加e结尾的形 容词直接加-ly。如：
polite-politely; wide-widely;wise-wisely;nice-nicely
3.以“y”结尾的，且读音为 / i/，先将“y”改成“i”，再加“ly”，如：
happy-happily; heavy-heavily;angry-angrily; busy-busily
但是如果读音为 / ai /，直接加ly，如：dry-dryly;sly-slyly; shy---shyly
4.以ic结尾的词，加ally，如：
economic-economically; basic-basically;scientific-scientifically; automatic-automatically;energetic-energetically;但是public-publicly例外。
5.以辅音字母加le结尾时,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时加ly，如：sole-solely。但是whole-wholly例外。
6. 以-ll结尾时，只须加–y，如：dull-dully;shrill-shrilly
需注意:有些以ly结尾的词是形容词而非副词。如：
friendly people; motherly care; lovely dog; monthlyexam; heavenlypeace; amanly sport
