Unit5Unit5同位语从句在主从复合句中，用作同位语的从句，叫同位语从句。同位语从句是用来解释说明前面名词的内容的从句。【要点精讲】1.同位语从句一般跟在某些名词后面， 如:idea,fact,news,hope,belief, suggestion,proposal,word,thought, doubt,truth,possibility,promise, order等，用以说明或解释该名词的 具体内容。这些名词一般都具备两个 特征：一、均为抽象名词；二、可以 涵盖一定的信息内容。如：Thenews

thatourteacher’sheathisfailingmadeussad.Ihavenoideawheretheyarespendingtheirholidays.Ihave______________hewillreturntoChina.我不知道他何时回中国。noideawhen2.同位语从句有时可以不紧跟在它所说明的名词后面,而是被别的词隔开,以使整个句子的结构显得平衡。如：

HegotthenewsfromMarythatthesportsmeetingwasputoff. Wordcamethatthepopstarwouldholdaliveconcertinourcity.3.同位语从句通常由that引导，但that 不在从句中充当成分，也不能省略； 同位语从句也可以由whether,when, where,how等引导。如：

Theyraisedthequestionwherewe shouldgo.Theproblem_________wecaneatmoresafelyhasattractedthegovernment’sattention.我们是否吃的更安全这个问题，得到了政府的关注。I________________shedidn’taccepttheniceoffer.我不知道她为什么不接受更好的机会。whetherhavenoideawhy4.当先行词为demand时，其后所跟同位语从句的谓语动词要用“should+动词原形”，其中，should也可省略。除demand外,这类名词还有advice,suggestion,order,request, requirement等。如：

Themanagermadeademandthatthe workers(should)finishthetaskahead oftime.【注意】同位语从句与定语从句的区别：①从词类上区别：同位语从句前面的名 词只能是idea,fact,news,hope,belief, suggestion等词；而定语从句的先行 词可以是名词、代词、主句的一部分 或整个主句。②从性质上区别：同位语从句是名词性从句，其作用相当于一个名词，是对前面的名词作进一步解释、说明；定语从句的作用相当于一个形容词，用来修饰前面的名词或代词。③从引导词及其在句中的成分上的区别：有些引导词如how,whether等可以引导同位语从句，但不能引导定语从句。定语从句的引导词均在从句中充当特定的句子成分。如：Iwon’tbelievethefactthatheliedtohismother.(that引导同位语从句，对fact进行说明，that不充当句子成分。)Iwon’tbelievethefact(that)hetoldme.(that引导定语从句对fact进行限定，that在从句中充当宾语。)用适当的连接词补全下面的对话。Jack:Tom,I'veheardthenews________youwonfirstprizeintheChineseSpeechContest.Congratulations!Tom:Thanksalot.I'mreallyexcited.Jack:I'dliketoaskyouwhyyouchosetostudyChinese.that
