英文形容词变副词规则
一般情况下直接加“ly”。
如quick-quickly; polite-politely; sad-sadly;imediate-immediately; recent-recently.
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.
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.
以ic 结尾的词，加ally。
如economic-economically; basic-basically;scientific-scientifically; automatic-automatically; energetic-energetically.
以辅音字母加le结尾时,去e加y——高考最喜欢考这一点规则。
如simple-simply; considerable-considerably;terrible-terribly.
元音字母加le结尾时，直接加 ly，如sole-solely。但是whole-wholly例外。
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;monthly exam; heavenly peace.
