副词和形容词同形（副词和形容词同形（AdverbsandAdjectivesIdenticalinForm））有的形容词同副词在词形上完全一样，但形容词起的是定语作用，而副词起的却是状语作用。如：Anearlyrisergetsupearly.Afasttraintravelsfast.Dailynewspapersarepublisheddaily.Thisishardwork.Wehavetoworkhard.区别副词和形容词常常依靠该词句法功能。如篻ostraight,tellsomeonestraight中为副词。在短语setsomeone/somethingstraight,putsomeone/somethingstraight,drinkwhiskystraight,keepone’sfacestraight中的straight看作形容词，因straight在些起宾语补足语的作用。英语中常有成对的副词：一个不带－ly,另一个由形容词加后缀－ly构成。这种有－ly的副词有时可同无－ly的副词互换，有时两者的用法和意义不一。但一般来说没有后缀－LY的副词表示动作所造成的结果、状态或给人的感觉，而,带有后缀－LY的副词则表示的动作方式。如：bright,brightlycheap,cheaplyShesellshergoodscheap.(cheap可用cheaply替换。在较为随便的谈话中，当动词是buy,sell时，常用cheap.clean,cleanlyThisknifecutscleanly.Thebulletwentcleanthroughthewall.Cleanthrough=rightthrough.作副词的clean含义为completely,right.在非正式语体里，它常跟动词forget,介词over,through,副词away,out连用。如：SorryIdidn’tturnup---ICLEANFORGOT.Theballsailedcleanovertheroof.Theprisonergotcleanaway.I’mafraidI’mcleanoutof(=havenomore)food.clear,clearlyStandclearofthedoorsofthetrain.副词clear跟of一起时，意为awayfrom,nottouching.Hethrewherclearacrosstheroom.Clearacross=rightacross“Isaiditveryloudandclear(clear=clearly);Iwentandshoutedinhisear.”HespokesoclearlythatIcouldheareveryword.close,closelyComeclose;Iwanttotellyousomething.(作副词时，“接近地，”“紧密地”，表具体近的程度)Theboyfollowedclosebehindhisfather.Thefellowstoodcloseagainstthewall.副词close是near之意，过去分词前常用closely.如：Theteacherwascloselyfollowedbyhispupils.Closely表示一种抽象的概念，“紧密地”“密切地”“严密地”。WeshouldcloselybeunitedaroundChairmanJiang.Shecloselyresembleshermother.Watchhimclosely.(=carefully,withattention)dead,deadlyTheroadisverydangerous.Godeadslow.(=exactly,completely,slow,可用slowly替换)还有deaddrunk,deadtired,deadright,deadsure,deadcertain等与deadslow同.Don’ttouchthat.It’sdeadly.(=adj.;fatal,causingdeath)It’sdeadlypoisonous.(=very)Ican’treadthis.It’sdeadlydull.(=very)Deep,deeplyDeep作副词时，常用来表示具体的深度，“深地”，修饰静止的状态和具体的动作。而deeply用来修饰情感的动词、形容词和过去分词，表示抽象的概念。Ourteachersoftenworkdeepintothenight.Hehadtodigdeeptofindwater.Weweredeeplymovedbywhathehaddone.I’mdeep
