1、 同位語從句誤區(qū)探秘同位語從句是對與之同位的名詞中心詞作進一步解釋，說明該名詞的具體內(nèi)容，一般由that引導(dǎo)。能接同位語從句的常見名詞有：idea, fact, news, belief, hope, evidence, opinion, problem, truth, answer, proposal, theory, decision, discovery, thought等。誤區(qū)一 引導(dǎo)同位語從句的that 可以省略that引導(dǎo)同位語從句時，僅起連詞作用，沒有實際意義，也不在從句中作任何成分，且表示肯定或明確意義，但不能省略。例1 Some researchers believe tha

2、t there is no doubt _ a cure for AIDS will be found.(05廣東） A. which B. that C. what D. whether【解題指導(dǎo)】在doubt, possibility, order, news, word, idea, hope, suggestion, information, plan, thought, fear, belief等名詞后，說明其具體內(nèi)容的從句是同位語從句，從句中不缺句子成分，意義非常完整，用that引導(dǎo)。故答案是B。例2 Danby left word with my secretary _ he w

3、ould call again in the afternoon.(05浙江) A. who B. that C. as D. which【解題指導(dǎo)】從句子的結(jié)構(gòu)和意義兩方面分析可知，空格后的從句說明的是word的具體內(nèi)容，表達(dá)了明確的意義，因此應(yīng)選用that引導(dǎo)同位語從句。同位語從句“that he would”與它所說明的名詞word被with my secretary分開了。Word這里是不可數(shù)名詞，意思為“話、口信”。誤區(qū)二 同位語從句只能用that引導(dǎo)同位語從句除了用連接詞that引導(dǎo)外，根據(jù)其結(jié)構(gòu)和意義，也可以由whether, 連接代詞who, what, whose, whic

4、h，連接副詞how, when, where, why，how等引導(dǎo)。在doubt, question, fear等表示“懷疑，疑問”等意義的抽象名詞后的同位語從句通常用whether引導(dǎo)，且表示不肯定或不明確，即含“是否”之意，此時從句也不缺句子成分。例3 The question _ it is right or wrong depends on situation. A. whether B. that C. what D. when 【解題指導(dǎo)】根據(jù)句意“是非正誤還是問題”解釋說明question的內(nèi)容，但又表明了不肯定的意義，因此此題應(yīng)選whether,表示“是否”。 當(dāng)idea作名

5、詞用于肯定句后面跟同位語從句時，根據(jù)句意以及句子結(jié)構(gòu)，可以用連接代詞who, what, whose, which，連接副詞how, when, where, why等引導(dǎo)同位語從句，且在從句中要充當(dāng)一定的句子成分。例4 Do you have any idea _ is actually going on in the classroom?(05遼寧) A. that B. what C. as D. which【解題指導(dǎo)】 根據(jù)所給信息判斷，as, which不能引導(dǎo)同位語從句，再根據(jù)句子結(jié)構(gòu)判斷，從句中缺少主語，故應(yīng)選what引導(dǎo)同位語從句。實際上這里是省去了介詞of的用法。誤區(qū)三 同位

6、語從句與定語從句混用同位語從句是說明名詞中心詞（往往是一些表事實或概念的抽象名詞）的具體內(nèi)容，that引導(dǎo)同位語從句時，起連詞作用，沒有實際意義，也不作句子的任何成分，一般不能省略；而定語從句是對先行詞加以修飾、限制，描述先行詞的性質(zhì)、特征，that在定語從句中充當(dāng)一定的句子成分，為關(guān)系代詞，作賓語時，that可以省略。例5 Theres a feeling in me _ well never know what a UFO is not ever.(02上海) A. that B. which C. of which D. what 【解題指導(dǎo)】根據(jù)句意判斷，從句well never kn

7、ow what a UFO is not ever作a feeling的同位語。解釋其具體內(nèi)容，故選答案that。that只起連接作用，不作從句的任何成分。 例6 We dont believe the news _ he told us yesterday. A. that B. what C. when D. how 【解題指導(dǎo)】根據(jù)句子結(jié)構(gòu)判斷，從句中謂語動詞told帶直接賓語，故應(yīng)判斷為定語從句，選答案that，在定語從句中作賓語。能用which嗎？可以省去嗎？為什么？The thought came to him _ he had no time to prepare for the
