专题08定语从句易混辨析【理论回顾】一、as引导的非限制性定语从句与it作形式主语的区别1.it做形式主语，可以代替___________________等，避免句子头重脚轻。2.as引导的非限定性定语从句，指代___________________。它引导的定语从句既可以位于主句的前面，也可以位于主句的___________________“”。它常翻译为正如，在这些从句中as作主语或宾语。例1：__________isknowntousall,paperwasfirstmadeinChina.例2：__________isknowntousallthatpaperwasfirstmadeinChina.二、that引导的定语从句与that引导的同位语从句的区别首先看引导从句的关系词that是否在从句中充当句子成分。如果在从句中充当主、宾、表，则是___________________。再看that前的名词是否是一些需要有内容的名词，如：idea,fact,thought,news等。后面的从句是说明其内容的，这个名词在后面的从句中不充当任何成分，这个从句则是___________________。例1：Thenews______camefromthefrontwastrue.例2：Thenews______hewonthegamewastrue.三、定语从句与强调句的区别1.强调句中that不充当成分，_____________省略定语从句中that充当成分，当充当的成分是宾语时，___________省略2.一般来说，如果将itis/was...与连接词去掉，句子仍然正确，就为__________________。这时就选用that连接词；否则就为___________________，其关系词的选择应根据先行词与从句的关系而定。例1：ItwasintheparkthatIsawKatelastweek.例2：ItwastheparkwhereIsawKatelastweek.例3：Itwasinthegardenofhisoldhouse______hegrewup______hedugupapotofgold.A.that;thatB.where;whereC.where;thatD.that;where四、非限制性定语从句与并列句的区别非限制性定从是补充说明主句，而并列句前后是并列关系，一样重要。并列句有特殊的___________________比如分号表示句子之间为并列关系，或者___________________and,but等。例1—：Hewrotealotofnovels,noneof__________werepopular.—It’sthesamewithhiswife.Shewrotesomeplays,butnoneof__________wasasuccess.A.these,themB.which,whichC.those,whichD.which,them例2：MrLihasthreedaughters,noneof________isanengineer.例3：MrLihasthreedaughters,butnoneof__________isadancer.例4：MrLihasthreedaughters;__________aredoctors.【想一想】例1：Itwasinthesmallhouse_____wasbuiltwithstonesbyhisfather____hespenthischildhood.A.which;thatB.that;whereC.which;whichD.that;which例2：Wheredidyoumeethim?Itisinthecinema____________Imethim.Itisinthecinema____________doorfaceswest.A．thatB．whereC．whoseD．which【练一练】一、辨析以下句子1.Ihavenoideawhenshewillbeback.______________________________________________________________2.ThefactthattheChinesepeopleinventedthecompassisknowntoall．______________________________________________________________3.“Wheredidyoufindtheprofessorwhomadethespeechyesterday?”“Itwasinthehallwherethestudentsoftenhaveameeting.”______________________________________________________________4.Itisontheislandthattheyspent10years.______________________________________________________________5.Itistheislandwheretheyspent10years.______________________________________________________________二、选择题1.Hehadthousandsofstudents,manyof______gainedgreatsuccessintheirownfield.A.whomB.themC.whichD.who2.Heaskedalotofquestions,noneof______waseasytoanswer.A.whichB.themC.whatD.that3.Heaskedalotofquestions,andnoneof______waseasytoanswer.A.themB.whichC.whatD.that4.Hetoldmethathehadtwogirl-friends,neitherof_______knewanythingabouttheother.A.whomB.themC.whichD.who5.Hetoldmethathehadtwogirl-friends,andneitherof_______knewanythingabouttheother.A.themB.whomC.whichD.who6.Hehadalotoffriends,onlyafewof______invitedtohiswedding.A.whomB.themC.whichD.who7.Theyputfo...
