1、分词作状语专题教案分词作状语专题适用学科英语适用年级高一适用区域全国课时时长120分钟知识点现在分词；过去分词教学目标使学生掌握分词作状语的各种题型的做题方法教学重点“分词作状语”题解题方法教学难点掌握分词作状语这类句式教学过程一、 复习预习分词的形式：1. 动词-ing形式；2. 动词-ed形式二、 知识讲解与例题精析分词作状语是高考考查的热点和重要考点，其热点考查内容如下：一、确定分词形式分词作状语时，通常放在句首，并且用逗号与主句隔开。同时，分词作状语时其逻辑主语与主句主语应保持一致，也就是说在确定选择现在分词还是过去分词时，要判断主句主语与分词中心词的关系。如果句子的主语是动词-ing

2、形式所表示的动作的发出者（即表主动或正在进行），分词形式选用现在分词；如果句子的主语是动词-ed形式所表示的动作的承受者时（即表被动或完成），分词形式选用过去分词。例：1,_,Istretchedmyhandoutforit.A.IsawthebookIwantedontheshellB.ThebookIwantedwasontheshellC.SeeingthebooklyingacrossthedeskD.Lyingonthedesk分析：分词作状语时，其逻辑主语应与句子的主语一致。根据这一原则，可知句子的主语I只能与see保持一致。如果选A,该句中没有连词，没能构成并列句和主从复合句，此

3、时要选用非谓语动词形式。所以选C2,Seenfromthehill,theparklooksverybeautiful.分析：“Seenfromthehill”是过去分词作状语。分词作状语时，其逻辑主语应与句子的主语一致。根据这一原则，可知，“thepark”是“Seenfromthehill”的逻辑主语，它们之间表示被动关系，所以分词形式用seen.二确立句子主语可能是谁确立句子主语可能是谁时，仍然遵循分词作状语时其逻辑主语与主句主语应保持一致的原则。反过来要根据分词形式确立句子主语。例：Havingbeenattackedbyterrorists,_.A.doctorscametothei

4、rrescue B.thetallbuildingcollapsedC.anemergencymeasurewastaken D.warningweregiventotourists分析:本题仍考查非谓语动词的用法。句中“Havingbeenattackedbyterrorists”是现在分词作状语。分词作状语时，其逻辑主语应与句子的主语一致。根据这一原则，可知“受攻击”的应是“thetallbuilding”,即“Havingbeenattacked”的逻辑主语是“thetallbuilding”.句意为“大楼因为受到恐怖分子的袭击而倒塌”.答案:B三独立主格结构分词作状语时其逻辑主语与主句

5、主语应保持一致，但当分词逻辑主语与主语不一致时，分词要有自己独立的逻辑主语，这种主语常常是名词或代词，置于动词-ing形式或动词-ed形式之前。这种名词/代词+动词-ing/动词-ed结构在语法上被称为独立主格结构。此时分词形式的选择取决于名词/代词与v-ing/v-ed形式所表示动作的逻辑关系，如果它们之间表示主动或分词动作正在进行，选择现在分词，如果它们之间表示被动或完成，选择过去分词。1,名词/代词+动词-ing例：Springcomingon,thetreesturnedgreen.2，名词/代词+动词-ed例：Thequestionsettled,theyfeltreleased.3

6、，with/without+名词/代词+动词-ing/-ed例：Withthetreegrowntall,wegetmoreshade.Ourschoollooksbeautifulwiththeflowerscomingout.Thebattlewasoverwithoutashotbeingfired.四分词作状语时，相当于一个状语从句。例：_weight,thedoctorhaswarnedmetokeepoffsugar.A.Imputtingon B.Havingputon C.AsImgaining D.Togain分析：在并列句和主从复合句中,逗号只起分隔作用,前后两部分的逻辑关

7、系必须使用连接词来表达;否则要使用非谓语动词.该题中B，C两项是非谓语动词作状语,但其逻辑主语与主句主语不一致,所以只能使用连接词来表达前后两部分的逻辑关系.答案:C五现在分词和过去分词作独立成分英语中一些特殊的分词可用作独立成分，不需要逻辑主语。这种无依着动词形式结构已经成为固定用法。常见的不需要逻辑主语的动词-ing/-ed形式结构:Considering(that)考虑到supposing(that)如果generallyspeaking一般说来franklyspeaking坦白说Judgingfrom从判断talkingof说到Concerning关于settingaside.除开Co

8、mingto谈到allowingfor.考虑到Proving/provided(that)假定supposing/suppose(that)假如Seeing(that)既然given(that)假设；如果；考虑到putfrankly坦白地说takenasawhole总的说来例：1.Putfrankly,Idontagreewithwhathesaid.坦白地说，我不同意他说的话。2.Giventhegeneralstateofhishealth,itmaytakehimawhiletorecoverfromtheoperation.考虑到他的一般身体状况，他手术后恢复过来可能需要一段时间。3.
