2、isproblem.________didn'thelp.辨析：定从:主从句间需用关系词连接；简单句：两个独立的句子，无任何关系词连接。技巧：标点符号是区分这类句子的切入点。Itwhich①题两个句子间用逗号连接且没有并列连词，显然是主从句关系，且为非限制性定语从句，需用关系代词which；②题中句号分隔两个句子，第二个句子中用It指代前一个句子。2.定语从句与并列句①Ihavethreebrothers，noneof________isateacher.②Ihavethreebrothers，butnoneof
3、________isateacher.③Ihavethreebrothers；________isateacher.whomthemnoneofthem定语从句:一般都是用关系代词或关系副词引起并列句:用but，so，and等表示转折、因果、并列关系的连词或分号连接。技巧：两分句之间是否有并列连词或分号①题是非限制性定语从句，用关系代词whom引导，被修饰的先行词brothers在从句中作of的宾语；②题有转折连词but，是并列句，要用代词them；③题是用分号连接的并列分句，后一句缺主语，可用none或none
4、ofthem。在其它情况下，除了none，代词all,both或表示数量的基数词亦可用在此类句型中。①OnMay5wereachedBeijing，wherewestayedforaweek.②OnMay5wereachedBeijing，andtherewestayedforaweek.③OnMay5wereachedBeijing；therewestayedforaweek.A.thereB.whereC.which(1)Hecametoschoollatethismorning,_________,ofco

7、muchhigherthanothers.whohewhoseits3.定语从句与强调句①ItwasOctober1st，1949________thePeople'sRepublicofChinawasfounded.②ItwasonOctober1st,1949________thePeople'sRepublicofChinawasfounded.强调句:“It＋be＋被强调部分＋that从句”。被强调部分可以是除谓语外任何其它成分，当被强调部分指人时，可用who(whom)代替that；当被强调部分是时间
8、或地点时（其前有介词），则不能用when或where代替that。把强调句中的it，be和that去掉，再把被强调部分还原，句子仍然成立定语从句:把it，be和that去掉,句子不成立。技巧：去掉it，be和that去掉,看句子成不成立①题是用关系副词when引导的定语从句，修饰主句的表语October1st，1949，这里的when相当于onwhich；②题为强调句，强
