【正文】 必修三Unit5 Noun clauses as the appositive同位語：對(duì)句子中某一成分作進(jìn)一步解釋、說明，與前面名詞在語法上處于同等地位的句子成分叫做 。（名詞、代詞、數(shù)詞和從句）Are you three ready to start out?They each can get a chance to travel by air.We have two foreign teachers, a Canadian and a American.The news that we’re having a holiday tomorrow is true.同位語從句：跟在名詞后，進(jìn)一步說明該名詞的具體內(nèi)容，作同位語的從句。它通常跟在某些名詞之后，如：advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word（消息），problem， question, doubt, thought等。They were delighted at the news that their team had won. Where did you get the idea that I could not e？有時(shí)同位語從句可以不緊跟在被說明的名詞后面，而被別的詞隔開。 The thought came to him that Tom might have returned the book.同為從句的連接詞：①that引導(dǎo)同位語從句時(shí)無詞義，也不充當(dāng)任何成分，但通常不可以省略。 He hasn’t made the decision whether he will go there. The news that Mr. Li will be our new English teacher is true.② whether引導(dǎo)同位語從句時(shí)意為“是否”，通常不能用if來代替。The question who should do the work is being discussed at the meeting.

The news that our team has won the final match is encouraging. 2. The news that you told us is really encouraging.② that的功能不同：that引導(dǎo)同位語從句時(shí)是一個(gè)純連詞，不充當(dāng)任何成分；而引導(dǎo)定語從句時(shí)，不僅起連接作用，而且還指代先行詞并在從句中充當(dāng)主語、賓語等成分。1. Dad made a promise that he would buy me a CD player if I passed the English test. 2. Dad made a promise that excited all his children.③ that引導(dǎo)同位語從句時(shí)是一個(gè)純連詞，故不能用which替換；而that引導(dǎo)定語從句時(shí)是代詞，常可以和另一關(guān)系代詞which替換。1. The fact that he is from Canada is new to me. 2. The fact that surprised me is that he is not Chinese. ④ 引導(dǎo)同位語從句的關(guān)聯(lián)詞，除that外，還可以根據(jù)句義使用任何其它疑問代詞或副詞；而定語從句不可用what, how, whether等引導(dǎo)。 had no idea at all what I should do next. 2. There is no proof whether he was killed by others.⑤ 當(dāng)when, why, where和how等引導(dǎo)的同位從句時(shí)，它們?yōu)檫B接副詞，雖然在句子中充當(dāng)成分，但前面沒有與其意義相同的先行詞；而在定語從句中它們有關(guān)系副詞，在其前面分別有表示時(shí)間，原因，地點(diǎn)和方式意義的名詞作先行詞。1.
