How【疑難討論】-【要點(diǎn)歸納】一、主語從句的概念作句子主語的從句叫主語從句。主語從句通常由從屬連詞that, whether和連接代詞what, who, which, whose, whichever, whatever, whomever, whoever以及連接副詞how, when, where, why等詞引導(dǎo)。that在句中無詞義，只起連接作用；連接代詞和連接副詞在句中既保留自己的疑問含義、又起連接作用，在從句中充當(dāng)從句的成分。例如：1. That light travels in straight

6、lines is known to us all.2. Whether we will go camping tomorrow depends on the weather.3. Whoever doesnt reach the Great Wall is not a true man.4. Who will give us a lecture on how to learn makes no difference.5. What is known to us all is that the 2008 Olympic Games took place in Beijing. 6. Where

7、the celebration will be held has not been announced.7. Why he was late for school this morning is not clear.8. Whichever of the customers comes in the shop everyday will receive a prize.二、主語從句的分類（一）由連接詞（that, whether）引導(dǎo)的主語從句。1. That he finished writing the composition in such a short time surprised

8、us all. 2. Whether we will go for an outing tomorrow remains unknown. （二）由連接代詞（what, who, which, whose, whichever, whatever, whoever）引導(dǎo)的主語從句。1. Who will be our monitor hasnt been decided yet. 2. Whom we must study for is a question of great importance. 3. What caused the accident remained unknown. 4

9、. Whatever you did is right. 5. Who the watch belongs to was lost is unknown. （三）由連接副詞（how, when, where, why, wherever, whenever, however）引導(dǎo)的主語從句。1. When they will start is not known yet.2. How this happened is not clear to anyone. 3. Wherever you are is my home. 4. However good you are is nonsense.

10、 5. Wherever he once lived is well preserved. 三、主語從句的注意事項(xiàng)（一）形式主語的句型為了使句子保持前后平衡，常把主語從句移至句子后部，而用it 作形式主語，但what，whatever， whoever引導(dǎo)的主語從句除外。常見的使用it作形式主語的句型有：1. It + be + 形容詞+ 從句能用于這種句型中的常見形容詞有：strange, natural, obvious, true, possible, clear, likely, impossible, surprising，amazing, uncertain, necessary等

11、。(1) It is not clear if the people will risk being attacked by sharks.(2) It is necessary that each of us should do our best to protect the environment.(3) It is strange that the man should have stuck to his silly ideas.2. It + be +名詞詞組+從句常用于這種句型的名詞詞組有：a pity, a shame, a fact, an honor, good news等。(

12、1) It is a pity that you cant stay here longer.(2) It is a great honor that I have been invited here today.(3) It is really good news that you have achieved the full scholarship of your school.(4) It is a law in science that energy cannot be created or destroyed.3. It + be + 過去分詞+從句常用于這種句型的過去分詞有：sai

13、d, reported, hoped, believed, expected, decided, thought, known, well-known, announced等。(1) It isnt decided whether we will go shopping next Sunday.(2) It is required in the regulations that you should not tell other people the password of your email account.(3) It is known to all that the gun powde

14、r was first invented by the Chinese. 4. It+ +不及物動(dòng)詞+從句常用于這種句型的過去分詞有：seems, happens, turns out, occurs, remains to be seen, doesnt matter(1) It seems that they know what they are doing.(2) It remains to be seen whether they can make great progress in this project.(3) It happened that she was out when

15、we called.(4) It didnt occur to him that he could get the first prize in the English speech contest.(5) It makes no difference where we shall have the meeting.(6) It doesnt matter whether she will come or not. 5. It+ +及物動(dòng)詞+賓語+從句 (1) It deeply shocked me what he said is not the way he did it. (2) It

16、doesnt interest me whether you succeed or not.(二) 主語從句中中的虛擬語氣1. 在“It is important (essential, strange, natural, necessary, appropriate, surprising, unfortunate, regrettable, shocking等 ) that”這類句型中，that所引導(dǎo)的主語從句中的謂語動(dòng)詞常用 (should)+動(dòng)詞原形結(jié)構(gòu)， 表示某事“重要”，“奇怪”，“喜悅”，“必要”“遺憾”等意義。例如： (1) It is important that we al

17、l should attend the meeting. (2) It is necessary that he (should) be sent to hospital at once. (3) It is necessary that we should clean the room every day.2. It was a pity ( a shame，no wonder) 表示驚奇、不相信、惋惜、理應(yīng)，竟然如此等,例如：(1) It was a pity (a shame, no wonder, etc.) that you should be so careless. (2) It

18、 was a pity that you should be so careless注意：這種從句表示的是事實(shí)如果說話人對(duì)這種事實(shí)表現(xiàn)出驚奇的情感，就可用虛擬語氣。反之，如果不表示驚奇等情感that從句也可用陳述語氣，例如： (1) It is true that he has made a very important discovery in chemistry.(2) It is a pity that we wont be able to go to the south to spend our summer vacation. (3) It is strange that he di

19、d not come yesterday. (4) It is a pity that you cant swim3. 在It + be+ suggested /advised/ordered/requested/ insisted/required 中, that從句的謂語也應(yīng)該用“should + 動(dòng)詞原形”的形式, should有時(shí)可以省略。例如：(1) It was suggested that we (should) take some effective measures to promote the sales.(2) It will be desired (suggested,

20、 decided, ordered, requested, proposed) that she should finish her homework this afternoon.(3) It is suggested that the work should be done with great care.(四) 主語從句作主語的單復(fù)數(shù)問題1. 主語從句一般看作第三人稱單數(shù)。例如：(1) That he finished writing the composition in such a short time is a big surprise to us all. (2) Whether

21、 we will go for an outing tomorrow remains unknown. (3) Who will be our monitor hasnt been decided yet. (4) When and where we will hold the meeting has not been decided yet. 2. what引導(dǎo)的主語從句做主語(1) 通常情況下，由what引導(dǎo)的主語從句放在句首時(shí)，其后的謂語動(dòng)詞一般用單數(shù)。例如：What caused the accident is not clear. What was once regarded as

22、impossible has now become a reality.(2) 當(dāng)主句中的表語是復(fù)數(shù)形式，或what從句的謂語動(dòng)詞及其補(bǔ)足語均為復(fù)數(shù)形式時(shí)，主句的謂語動(dòng)詞應(yīng)用復(fù)數(shù)。例如：What he gave me are five English books. What are used as chief building materials today are steels and concrete. (3) 當(dāng)what引導(dǎo)的主語從句是一個(gè)由and連接的并列結(jié)構(gòu)時(shí)，應(yīng)根據(jù)句意確定其表達(dá)的單復(fù)數(shù)意義，然后決定主句謂語動(dòng)詞的單復(fù)數(shù)形式。What he says and acts does n

23、ot concern me. What he says and acts do not agree.What I say and what I think is no business of yours.What you eat and how much you exercise are important factors in a weight loss program.What caused the accident and who was responsible for it remain unknown to us. (五) what與that 在引導(dǎo)主語從句時(shí)的區(qū)別what 引導(dǎo)主語

24、從句時(shí)在句時(shí)在從句中充當(dāng)句子成分，如主語賓語表語，而that 則不然，that 只起連接作用,不做成分。例如：(1) What (The words that) he said at the meeting excited everybody present. (2) That she is still alive is a consolation. 【基礎(chǔ)訓(xùn)練】根據(jù)句子的意思，從A、B、C、D四個(gè)選項(xiàng)中選擇最佳答案。1. _ makes this shop different is that it offers more personal services. A. What B. Who C
