I dont know about the fact that he is a teacher.三、知識(shí)講解知識(shí)點(diǎn)1：同位語從句的定義在句中充當(dāng)同位語成分，一般跟在一些抽象名詞后，如（evidence 證據(jù)/ promise承諾、允諾/notice通知/news/idea/fact/word消息/truth/belief/possibility/problem/hope/desire/thought/suggestion）,對(duì)前面的名詞起補(bǔ)充說明的作用。Word came that our football team won the match.The idea that computers can recognize human voices surprises many people.I have no idea whether the meeting will be held.劃線部分是同位語從句。知識(shí)點(diǎn)2：同位語從句的引導(dǎo)詞連詞：that, whether連接代詞：who, whom, what, whose連接副詞：when ,where, how, why 等。注：if ,which 不能引導(dǎo)同位語從句He must answer the question whether he agrees to it or not. 他必須回答他是否同意這樣一個(gè)問題。 知識(shí)點(diǎn)3：同位語從句的語序同位語從句的語序是陳述句語序即：連接代詞/副詞+主語+謂語+其他成分。例句如下：My question how I can get in touch with him has not been answered.知識(shí)點(diǎn)4：間隔同位語從句 同位語從句通常是跟在它解釋或說明的名詞后，但有些情況下，由于句子結(jié)構(gòu)的原因，同位語從句不緊跟在名詞后，而被其他的詞隔開。 A warm thought suddenly came to me that I might use the pocket money to buy some flowers for my mother's birthday 簡(jiǎn)析：由于that從句太長(zhǎng)，為避免句子失去平衡，此處用了間隔同位語從句 知識(shí)點(diǎn)5： 虛擬語氣在同位語從句中的應(yīng)用含有表示“請(qǐng)求、建議、命令、要求”等意義的詞的主語從句、賓語從句、表語從句和同位語從句中，常用虛擬語氣， 結(jié)構(gòu)為：（should）+ 動(dòng)詞原形。這類詞有：一堅(jiān)持insist，二命令order, command，四建議suggest, advise, recommend,propose,四要求 demand, request, require, desire, etc.It is suggested that the meeting (should)be put off till next week.She insisted that we stay at her house instead of a hotel.Her suggestion was that there (should) be a map of the world in each office.The headmaster made the request that we (should) obey the traffic rules in a foreign country.注意：suggest表示“暗示、表明”時(shí)， 后面從句不用虛擬語氣。Her pleased look suggests that she has won the game. 從句動(dòng)作在insist之后發(fā)生 虛擬語氣insist 從句動(dòng)作在insist之前發(fā)生 陳述語氣She insisted that she heard someone in the next room.I insisted that you (should) be there on time.She insisted the man stole her purse and be sent to the police station.知識(shí)點(diǎn)6：幾點(diǎn)注意事項(xiàng)1. 只用whether不用if的情況：（1）表語從句和同位語從句 （2）介詞后 (3)與or not連用 （4）與不定式連用 （5）主語從句句首My question is whether he leftIt all depends on whether they will support them.I dont care whether he comes or not.Idont know whether to go there.whether the meeting will be held is still a problem.2. 在以下情況中that不能省略(1)當(dāng)句中的動(dòng)詞后接多于兩個(gè)由that引導(dǎo)的賓語從句時(shí)，第一個(gè)that可省，但后面的that不可省。例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.(2)當(dāng)主句的謂語動(dòng)詞與that賓語從句之間有插入語時(shí)，that一般不可省。例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.(3)當(dāng)that從句是雙賓語中的直接賓語時(shí)，that不可省。例句：I cant tell him that his mother died.(4)當(dāng)it作形式賓語時(shí)，that不可省。例句：I find it necessary that we should do the homework on time.（5）表語從句和同位語從句中that一般不省略。The trouble is that I have lost his address.The idea that you can do this work well without thinking is quite wrong.四、例題精析【例題1】- Is it true that Mike refused an offer from Yale University yesterday?- Yeah, but I have no idea _ he did it; that's one of his favorite universities.A. when B, why C. that D. how【答案】B【解析】why he did it 是idea的同位語從句，考查連接副詞?！纠}2】The only way to succeed at the highest level is to have total belief _ you are better than anyone else on the sports field.A how B that C which D whether【答案】B【解析】that you are better than anyone else on the sports field是total belief的同位語從句，考查連詞?！纠}3】Evidence has been found through years of study_ childrens early sleeping problems are likely to continue when they grow up.A. why  B. how   C. whether D. that【答案】D【解析】that childrens early sleeping problems are likely to continue when they grow up是Evidence的同位語從句，屬于間隔同位語從句。課程小結(jié)本節(jié)課主要學(xué)習(xí)了同位語從句，包括連接詞的選擇、語序、和虛擬在此種從句中的應(yīng)用。
