1、Unit2 Witnessing time名詞性從句名詞性從句: 即指性質(zhì)相當(dāng)于名詞的從句，它包括主語從句、賓語從句、表語從句和同位語從句。 一、引導(dǎo)名詞性從句的連接詞 連接代詞：who, whom, whose, what, which, whoever, whatever, whichever 連接副詞：when, where, how, why, whenever, wherever, however連接詞：whether, if “是否”不充當(dāng)句子的任何成分。 that只能起連接主句和從句的作用，不充當(dāng)從句的任何成分，無詞義。二、名詞性從句的分類1. 主語從句：用作主語的從句叫主語從句
2、。That she likes such kind of films is very interesting. Whether he will come remains a question. What she is doing is none of your business.Whoever comes will be welcome.Where he has been is still a puzzle.However you do it is all right with me.2. 表語從句：表語從句在句中作表語，它位于主句的系動(dòng)詞之后。The problem is that smok
3、ers cannot go without smoking. 問題是抽煙的人不抽煙就會(huì)感到難受。 The question is whether it is worth doing. 問題是這是否值得做。China is no longer what it used to be. 中國(guó)已不是從前那個(gè)樣子了。This is where he has worked for years. 這就是他多年工作的地方。3. 賓語從句：在句中可以作謂語動(dòng)詞或介詞或某些形容詞的賓語。They know that the habit may kill them. They doubt whether or no
4、t Jack is a good student. The teacher is satisfied with what she has said. Im glad that I can go with you.4. 同位語從句: 同位語從句說明其前面的名詞的具體內(nèi)容?？捎糜谕徽Z從句的名詞有advice, fact, demand, doubt, hope, idea, information, message, news, order, problem, promise, question, request, suggestion, truth, wish, word等。The news
5、that we won the game is exciting.I have no idea when he will come back home. Word came that our football team had won the match. 三、名詞性從句中的注意點(diǎn)主語從句：1. 有時(shí)用形式主語it代替主語從句作形式主語放于句首，而把主語從句置于句末。常用句型如下。1) It is +名詞+ that (名詞: a pity/no wonder/a pleasure) eg. It is a pity that my new computer doesnt work.2) It
6、 is +形容詞+ that (形容詞若是strange, necessary, important, natural 主語從句得用虛擬語氣should +v.eg. Its necessary that you complete the design before National Day. 3) It is +過去分詞+ that (常用動(dòng)詞: report, say, tell, believe, think )eg. Its said that the sports meet will be put off. 4) It + 不及物動(dòng)詞+that eg. Itoccurredtomet
7、hat I had told him the news. 我突然想起來我已經(jīng)告訴他這個(gè)消息了。2. 使用主語從句應(yīng)注意。1) 從句作主語，謂語常用單數(shù)，但以what開始的主語從句，如后面的表語為復(fù)數(shù)時(shí)，謂語也用復(fù)數(shù)。eg. What he wants to buy are three books and two ball pens.What he wanted to see was an end to all the armies of the world.2) that從句位于句首時(shí)，that絕對(duì)不能省略。That we are invited to the concert is good
8、news to us.3. It 作形式主語和引導(dǎo)強(qiáng)調(diào)句的比較。 It作形式主語代替主語從句，主要是為了平衡句子結(jié)構(gòu)，主語從句的連接詞沒有變化。而it引導(dǎo)的強(qiáng)調(diào)句則是強(qiáng)調(diào)句子某一部分，無論強(qiáng)調(diào)的是什么成分，都可用連詞that。被強(qiáng)調(diào)部分指人時(shí)也可用who/whom。eg. a) It is a pity that you didnt go to see the film. 你不去看那場(chǎng)電影真可惜。 b) It doesnt interest me whether you succeed or not.我對(duì)你成功與否不感興趣。 c) It is in the morning that the m
9、urder took place.謀殺案是在早上發(fā)生的。（強(qiáng)調(diào)句型） d) It is John that broke the window. 是John打碎的窗戶。（強(qiáng)調(diào)句型）賓語從句：1. 連接詞that引導(dǎo)的賓語從句，若主句動(dòng)詞后有兩個(gè)或以上的賓語從句，除第一個(gè)that外，其余均不可省。eg. I forgot (that) my papers was due on Tuesday and that my teacher had said he would not accept late papers. 2. 在demand, order, suggest, decide, insist
10、, desire, request, command等表示要求、命令、建議、決定等意義的動(dòng)詞后，賓語從句常用“（should）+ 動(dòng)詞原形”。eg. I insist that she (should) do her work alone. 我堅(jiān)持要她自己工作。3. 注意賓語從句中的時(shí)態(tài)呼應(yīng)。1）當(dāng)主句動(dòng)詞是現(xiàn)在時(shí)，從句根據(jù)自身的句子情況，而使用不同時(shí)態(tài)。eg. He studies English every day. （從句用一般現(xiàn)在時(shí)）eg. He studied English last term. （從句用一般過去時(shí)）eg. He knows (that) he will study
11、 English next year. （從句用一般將來時(shí)）eg. He has studied English since 1998. （從句用現(xiàn)在完成時(shí)）2）當(dāng)主句動(dòng)詞是過去時(shí)態(tài)，從句則要用相應(yīng)的過去時(shí)態(tài)，如一般過去時(shí)，過去進(jìn)行時(shí)，過去將來時(shí)等；當(dāng)從句表示的是客觀真理，科學(xué)原理，自然現(xiàn)象，則從句仍用現(xiàn)在時(shí)態(tài)。eg. The teacher told us that Tom had left us for America. She told me that the earth turns around the sun.表語從句：1. 表語從句的表現(xiàn)形式除了用從屬連詞，連接代詞和連接副詞引導(dǎo)以
12、外，還可用as, as if, as though。Things were not as they seemed.It looks as if it is going to rain.2. 另外還要注意以下常用的兩種結(jié)構(gòu)。The reason why is that eg. The reason why he was fired is that he didnt work hard.That is because eg. He was late for school yesterday. That is because he was ill. (because 說明理由) That is wh
13、y eg. He was ill. That is why he was late for school. (前面說明理由，why引導(dǎo)從句表結(jié)果) 同位語從句：1. 凡表示“請(qǐng)示、建議、命令”等動(dòng)詞的相應(yīng)的名詞引導(dǎo)的同位語從句，均用 (should) +v. 原形如：order, advice, suggestion, demand, proposal eg. The suggestion that he (should) not go there is of great value. 2. 同位語從句和定語從句的區(qū)別。 1) 定語從句中的that既代替先行詞，同時(shí)以在從句中作某個(gè)成分（主語或
14、賓語），而同位語從句中的that是連詞，只起連接主句與從句的作用，不充當(dāng)句中任何成分。 2) 定語從句是形容詞性的，其功能是修飾先行詞，對(duì)先行詞加以限定，描述定的性質(zhì)或特征；同位語從句是名詞性的，其功能是對(duì)名詞進(jìn)行補(bǔ)充說明。eg. The news that he told me is that Tom would go abroad next year.（他告訴我的消息是湯姆明年將出國(guó)。）（第一個(gè)that引導(dǎo)的從句是定語從句，that在從句中作賓語） The news that Tom would go abroad is told by him.（湯姆將出國(guó)的消息是他講的。）（同位語從句，
15、that在句中不作任何成分） 四、名詞性從句中應(yīng)注意的其它情況1. whether 與 if 的區(qū)別 1) 在賓語從句中可互換: eg. I dont know whether/if he will come this evening.2) 在表語、同位語從句中只能用whether: eg. The question is whether the film is worth seeing.3) 在主語從句中，只有用it作形式主語時(shí)，whether, if都能引導(dǎo)主語從句，而if引導(dǎo)的主語從句只能放在句尾，否則也只能用whether。eg. Whether we shall attend the
16、 meeting hasnt been decided. It is not sure if he will succeed.4) 在介詞后只用whether: eg. I havent settled the question of whether Ill go back home.5) 直接跟動(dòng)詞不定式時(shí)也只用whether: eg. He doesnt know whether to stay or not.6) 后面緊跟or not 只用whether。 eg. Whether you like it or not, you must do it well. We didnt know
17、 whether or not she was ready. 7) 某些動(dòng)詞后（discuss/depend）只用whether: eg. It all depends (on) whether they will support us.We must discuss whether he will be allowed come here.2. 名詞性從句的語序: 不管什么詞引導(dǎo)，從句的語序始終用陳述語序。eg. I dont know why he was crying. 我不知道她為什么哭。The question is why there is little rain here. 問題
18、是這里為什么雨水少。 3. Who/whoever,what/whatever等的用法區(qū)別 一般說來，what/who等含特指意義，而whatever/whoever等含泛指意義，意為“無論什么/無論誰”。 eg. Itisgenerallyconsideredunwisetogiveachildwhatever heorshewants. (這里的whatever表泛指意義) 無論孩子要什么就給他/她什么事不明智的Icantrememberatthemomentwhohassaidthewords.(這里的who表特定的某人) 4. that與what引導(dǎo)名詞性從句的區(qū)別what用來引導(dǎo)各種
19、名詞性從句，并在從句中做主語、賓語或表語，意為“所的事或物”。 eg. What I need is more time. (what引導(dǎo)主語從句，并在從句中做need的賓語)The boy isnt what he used to be. (what引導(dǎo)表語從句，并在從句中做be的表語) I have no idea what has happened to her. (what引導(dǎo)同位語從句，并在從句中做主語)that 也可用來引導(dǎo)名詞性從句，但 that本身無意義，也不在從句中做任何成分，僅僅起一個(gè)連接的作用。 eg. The teacher taught us that we shou
