【正文】 promise, information, conclusion, order, suggestion, problem, question, thought, report, belief, decision, doubt, opinion, theory等抽象名詞。例如： The news that his heath is failing made us sad. 他健康狀況不佳的消息使我們很難過。// I have no idea where they are spending their holidays. 我不知道他們在哪里度假。// The question who should do the work requires 。// There is no doubt that he will e here ， 這是毫無疑問的。// He was tortured by the doubt whether he would accept their 。　　掌握同位語從句的用法要注意以下兩個(gè)問題：　　1. 同位語從句有時(shí)可以不緊跟在它所說明的名詞后面， 而是被別的詞隔開， 以使得整個(gè)句子的結(jié)構(gòu)顯得平衡。例如：He got the news from Mary that the sports meeting was put off. 他從瑪麗那里獲知了運(yùn)動(dòng)會(huì)被推遲的消息。// Word came that Hussein had been captured. 侯賽因已被捕的消息傳來。2. 同位語從句和定語從句結(jié)構(gòu)相似， 通常位于某一名詞或代詞后面， 但兩者存在明顯區(qū)別： 同位語從句對名詞性成分加以補(bǔ)充說明， 是該名詞性成分具體內(nèi)容的體現(xiàn)(相當(dāng)于名詞的作用)。 that引導(dǎo)的同位語從句中引導(dǎo)詞that不在該同位語從句中充當(dāng)句子成分， 但不能被省略， 同位語從句還可以用whether、 how等連詞引導(dǎo)(定語從句則不能)。定語從句對先行詞加以限制或修飾、 說明先行詞的性質(zhì)或特征(相當(dāng)于形容詞的作用)， 定語從句的引導(dǎo)詞均在該定語從句中充當(dāng)特定的句子成分(that在其引導(dǎo)的限定性定語從句中充當(dāng)主語、 賓語或者表語， 充當(dāng)定語從句中賓語的that經(jīng)?？杀皇÷?。注意體會(huì)以下四組例句：　　(1) 第一組例句：　?、?We can39。t solve the problem how we can travel faster than ?！　?how引導(dǎo)的從句表示其前面的名詞the problem的具體內(nèi)容， 屬于同位語從句)　?、?I can39。t remember the problem that they ?！　?引導(dǎo)詞that就是that引導(dǎo)的從句中have的賓語， the problem的具體內(nèi)容也沒有得到說明， 故本句中that引導(dǎo)的從句是修飾problem的定語從句)　　(2) 第二組例句：　?、?I won39。t believe the fact that he lied to his ?！　?that引導(dǎo)同位語從句對fact的具體內(nèi)容進(jìn)行說明， that在其中不充當(dāng)具體的句子成分)　?、?I won39。t believe the fact (that) he told ?！　?that引導(dǎo)定語從句對fact進(jìn)行限定， that在該從句中充當(dāng)賓語)　　(3) 第三組例句：　　① The news that Tom would go abroad is told by 。　　(that引導(dǎo)同位語從句對news的具體內(nèi)容進(jìn)行說明， that在其中不充當(dāng)具體的句子成分)　　② The news that he told me is that Tom would go abroad next year. 他告訴我的消息是湯姆來年將出國?！　?句中的第一個(gè)that引導(dǎo)定語從句限定先行詞news， 第二個(gè)that引導(dǎo)表語從句)　　(4) 第四組例句：　　① We have no idea at all where he has 。　　(where引導(dǎo)同位語從句說明idea的具體內(nèi)容)　?、?That39。s the place where he was ?！　?where引導(dǎo)定語從句限定先行詞place)例題講解：［考題1］ There is much chance ____ Bill will recover from his injury in time for the race.
