副詞的構(gòu)成
從形態(tài)上看，大多數(shù)副詞都是由"形容詞+后綴-ly"構(gòu)成的，例如：slowly, heavily, truly, terribly等。
形容詞變副詞：
①.在形容詞詞尾直接加-ly。如:real-really; helpful-helpfully; careful-carefully; slow-slowly; quick-quickly; quiet-quietly
②.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
③.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
注意: friendly; motherly; lovely，weekly，lively等詞是形容詞而非副詞。
④.英語中還有少數(shù)與形容詞同形的副詞，例如：daily, early, fast, hard, high, long, near, straight, well等。請比較它們的詞義和用法：
the high jump 跳高項目(形容詞) to jump high 跳得高(副詞)
a fast car 行得快的汽車(形容詞)to drive fast 開快車(副詞)
an early riser 早起的人(形容詞)to get up early 起得早(副詞)
a straight line直線(形容詞)Go straight ahead. 一直朝前走。(副詞)
注意：兼有兩種形式的副詞
①.late 與lately：
late意思是"晚"; lately 意思是"最近"。例如：You have come too late. What have you been doing lately?
②.deep與deeply：
deep意思是"深"，表示空間深度;deeply時常表示感情上的深度，"深深地"。例如：He pushed the stick deep into the mud. Even father was deeply moved by the film.
③.high與highly：
high表示空間高度;highly表示程度，相當于much 。例如：The plane was flying high. I think highly of your opinion.
④.wide與widely：
wide表示空間寬度;widely意思是"廣泛地"，"在許多地方" 。例如：He opened the door wide. English is widely used in the world.
