2、isproblem.________didn'thelp.辨析:定從:主從句間需用關(guān)系詞連接;簡單句:兩個獨立的句子,無任何關(guān)系詞連接。技巧:標(biāo)點符號是區(qū)分這類句子的切入點。Itwhich①題兩個句子間用逗號連接且沒有并列連詞,顯然是主從句關(guān)系,且為非限制性定語從句,需用關(guān)系代詞which;②題中句號分隔兩個句子,第二個句子中用It指代前一個句子。2.定語從句與并列句①Ihavethreebrothers,noneof________isateacher.②Ihavethreebrothers,butnoneof
3、________isateacher.③Ihavethreebrothers;________isateacher.whomthemnoneofthem定語從句:一般都是用關(guān)系代詞或關(guān)系副詞引起并列句:用but,so,and等表示轉(zhuǎn)折、因果、并列關(guān)系的連詞或分號連接。技巧:兩分句之間是否有并列連詞或分號①題是非限制性定語從句,用關(guān)系代詞whom引導(dǎo),被修飾的先行詞brothers在從句中作of的賓語;②題有轉(zhuǎn)折連詞but,是并列句,要用代詞them;③題是用分號連接的并列分句,后一句缺主語,可用none或none
4、ofthem。在其它情況下,除了none,代詞all,both或表示數(shù)量的基數(shù)詞亦可用在此類句型中。①OnMay5wereachedBeijing,wherewestayedforaweek.②OnMay5wereachedBeijing,andtherewestayedforaweek.③OnMay5wereachedBeijing;therewestayedforaweek.A.thereB.whereC.which(1)Hecametoschoollatethismorning,_________,ofco

8、或地點時(其前有介詞),則不能用when或where代替that。把強(qiáng)調(diào)句中的it,be和that去掉,再把被強(qiáng)調(diào)部分還原,句子仍然成立定語從句: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題是用關(guān)系副詞when引導(dǎo)的定語從句,修飾主句的表語October1st,1949,這里的when相當(dāng)于onwhich;②題為強(qiáng)調(diào)句,強(qiáng)
