名詞性從句（賓語從句、表語從句、主語從句）講解與練習(xí)

1、.名詞性從句賓語從句、表語從句、主語從句六大根本句型1主系表句型- be 連系動詞do2、主謂賓- dovt3、主謂- dovi-不及物動詞4、主謂賓補-dovt5、主謂賓賓-dovt 記雙賓語的動詞一定要記。6、There be 不及物動詞do-be 不及物動詞賓語從句定義：在主謂賓句型的賓語的位置上把做為名詞的賓語擴展成一個be句型或者do句型?？梢杂靡韵鹿竭M展表示：主語+謂語+從句。賓語從句的連詞 that , whetheror not或if; whichwhichever, whowhoever，who

2、mwhomever ，whosewhosever，whatwhatever; whenwhenever，wherewherever， why，howhowever;  how many, how much, how long, how often，how soon賓語從句的形式：1、主謂賓句型的賓語從句: 作為名詞的賓語擴展成一個be句型或者do句型。He knows the newsHe knows that the teacher is in classroom2、主謂賓賓-dovt 句型的賓語從句，把直接賓語變?yōu)橐粋€be或do句

3、型。He tells me the newsHe tells the news to meHe tells me that she is a teacherHe tells that she is a teacher to me3、主謂賓補句型的賓語從句需要it來做形式賓語I find Chinese important主 謂 賓 補I find that we make a quick decision about this matter important主 謂 賓語從句

4、 補I find it important that we make a quick decision about this matter主 謂 形式賓語 補 賓語從句I think it necessary that we take plenty of hot water every day .我認(rèn)為每天多喝開水是有必要的.I feel it a pity that I havent been to the get-together.我沒去聚會,感覺非常遺憾.I have made it a rule that

5、I keep diaries.我每天寫日記成了習(xí)慣.4、賓語從句的省略形式：某些形容詞后面可以帶賓語從句，其形式為sb+be+形容詞+that賓語從句：這一類形容詞通常是表示人物的心理，情感等狀態(tài)的形容詞如：sure, certain, glad, please, happy, sorry, afraid, satisfied, surpriseda. I am glad that you helped me.b、I am sure that you can pass the exam.1、I am glad of your help.2、I am sure about your exam.分

6、析：上面句子中介詞后面所跟成分都做介詞賓語。我們完全可以將他們換成that+陳述句:3、 I am glad of that you helped me.4、 I am sure about that you can pass the exam.從語法上講，以上的構(gòu)造都是正確的。但是，由于這樣表達(dá)過于啰嗦，所以我們可以將其簡化，省去介詞，由于它們是賓語從句，所以連同that也可以省掉，因此，這是一種省略形式的賓語從句。表語從句同樣的道理，假如在主系表句型表語的位置上把表語變成一個be句型或者do句型，那么稱為表語從句。 The question is difficult -

7、_the question is how we make money .主語 系 表 主語 系 表語從句 The question is difficult - the question is that she is a thief主語 系 表語從句The question is difficult -the question is that there is a thief in the room主語 系 表語從句 事實是因為每個人都要生活- the fact is because

8、everyone must live小結(jié)：表語從句的引導(dǎo)詞與賓語從句一樣，規(guī)律與賓語從句一樣，只不過稱呼不同而已，因此掌握賓語從句以后，表語從句無需特別學(xué)習(xí)。但要注意以下幾點：1、不可以用if，而用whether 連接表語從句as if 例外。False: The question is if the enemy is marching towards us.錯誤Right: The question is whether the enemy is marching towards us.正確2、that在表語從句中不可以省掉。the question is

9、60;that she is a thief3、注意比較That is because.句型與that is why.句型“That is because.與“That is why.之間的不同在于“That is because.指原因或理由，“That is why.那么指由于各種原因所造成的后果。例如：1：He did not see the film last night.That is because he had to help his little sister with her homework.2、He had seen the film bef

10、ore.That is why he did not see it last night.第一句話說明原因， 第二句話說明結(jié)果4、當(dāng)主語是reason, fact，idea等抽象名詞時，表語從句的連接詞應(yīng)該用that.The reason is that he didnt go to schoolThe traditional view is _ we sleep because our brain is “programmed tomake us do so.A when B. why C. whether D. thatYou are saying

11、that everyone should be equal, and this is _ I disagree.A. why B. where  C. what D. how主語從句假如將主謂賓或主系表的主語擴展成為一個句子，稱為主語從句： The question is difficult -that she makes money is difficult主語 系 表 主語從句 系 表- it is difficult that she makes money形式主語 系 表 真正的主語It= that she makes money 主語從句的構(gòu)造：it is.that.the

12、 cat is a fact - that there is a cat in the room is a fact主語從句it is a fact that there is a cat in the room形式主語 系 表 真正主語he knows the news- that he knows the news surprises meIt surprises me that he knows the news小結(jié)：主語從句的引導(dǎo)詞與賓語從句一樣，規(guī)律與賓語從句一樣，只不過稱呼不同而已，因此掌握賓語從句以后，主語從句無需特別學(xué)習(xí)。但需要注意兩點：1,主語從句有形式主語it2, 

13、;引導(dǎo)詞if不能引導(dǎo)主語從句，只能用whether.or notIf 不能引導(dǎo)主語從句他明天是否上學(xué)還不知道 if he will go to school is unclear 錯誤 it is unclear if he will go to school錯誤Whether he will go to school is unclear It is unclear whether he will go to school 正確3、以下幾點需要注意：It 作形式主語和it引導(dǎo)強調(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

14、子構(gòu)造，主語從句的連接詞沒有變化。而it引導(dǎo)的強調(diào)句那么是對句子某一部分進展強調(diào)，無論強調(diào)的是什么成分，都可用連詞that。被強調(diào)部分指人是也可用who/whom。例如：It is a pity that you didnt go to see the film.It was the football team and It hadwho helped the old man4、1 主系表的主語從句形式 it +系+表+從句It is a fact that 事實是It is natural that 很自然2主謂賓的主語從句形式：it+謂語及物動詞+賓語+從句3主謂的主語從句形式：

15、 it +謂語不及物動詞從句It seems that 似乎It happened that 碰巧4主謂賓賓的主語從句形式：it +謂語+賓語+賓語+從句5主謂賓補的主語從句形式：it +謂語+賓語+補語+從句穩(wěn)固練習(xí)1. Nowadays consumers become more and more practical and buy only _they need.
