第一篇:Lecture 8 名詞性從句教案
Lecture8 名詞性從句Nominal Clauses
一、名詞性從句的概念
在句子中起名詞作用的句子叫名詞性從句。名詞從句的功能相當于名詞詞組,它在復合句中能擔任主語、賓語、表語、同位語、介詞賓語等,因此根據它在句中不同的語法功能,名詞性從句又可分為主語從句、賓語從句、表語從句和同位語從句。
引導名詞性從句的連接詞可分為三類。
無成分連接詞:that,whether, if不充當從句的任何成分。
做成分的連接代詞:what, whatever, who, whoever, whom, whose, which.做成分的連接副詞:when, where, how, why.二、主語從句Subject Clauses 2.1主語從句的概念
主語從句是名詞性從句的一種,在主句中作主語,由連詞that,whether;連接代詞who, whom, whose, what, which, whatever, whoever, whichever;連接副詞when, why, where, how等詞來引導。連詞that只起連接作用,無實義。Whether作“是否”來解。2.2 主語從句的結構
(1)主語從句+謂語,從句用正常語序,沒有助動詞;主句的謂語動詞,一般用單數。That he was chosen made us very excited.Whether(or not)she will come to our party depends on her health.What they need is food and clean water.Who will be elected chairman remains a question.Which team will win the match is still uncertain.(2)It+is+形容詞(名詞詞組、過去分詞)+that從句:此結構中,由于主語過長,為保持句子平衡,用it作形式主語,that引導的主語從句后置。A.It is + adj.+that 從句
形容詞常為:clear, abvious, likely, true, certain, strange, natural, surprising, good, wonderful, funny, possible, probable….It is clear that their team will win.It is surprising that he made so many mistakes in the quiz.B.It+is+名詞詞組(commone knowledge, no wonder, an honour, a good thing, a pity, no
surprise ect.)+that?
It is an honour that she was elected representative of her team.It is no surprise that he failed the exam.C.It+be+過去分詞(said,reported,pointed out, thought, expected, decided, announced, arranged, believed, known to all, etc.)that… It is said that she was born in a noble family.It is reported that the minister was shot dead in the head.該結構中,某些形容詞、名詞詞組、過去分詞、that從句中的謂語動詞要用虛擬式。常見的形容詞/名詞詞組有:
essential(絕對必要的),important, advisable(明智的),desirable(希望能夠的), imperative(必須的),natural, necessary, regretful, strange, proper, urgent, duty, a pity, no wonder(難怪),a regret.It is strange that he(should)say so.It is important that the project be finished on time.It is no wonder that he(should)get so angry at it.D.It+seem(happen等不及物動詞及短語)+that
It seems/happens/appears/matters/occurred to me that Mary is not coming today.E.It +doesn’t matter(makes no difference, ect)+連接代詞或連接副詞引導的主語從句。
It doesn’t matter whether she will come or not.It makes no difference where we shall have the meeting.三、表語從句Predictive Clauses
表語從句在復合句中作表語,位于主句的系動詞之后,用以說明主語的內容??山颖碚Z從句的聯系動詞有be, look, seem, sound, appear等。
1.主語為名詞:fact, truth, cause, question, explanation, trouble, problem, assumption, belief及代詞this, that, these, those, it等的表語從句。The fact is that he didn’t finish his homework last night.This is just what we need at present.That is where the problem lies in.That引導的表語從句時,在句中無詞義,只起連接作用,但不可省去。
What 引導的主語從句后的表語從句。
What I want to know is which dictionary I should buy.What 引導的主語從句表示結果或名詞reason作主語時,后面的表語從句表示原因時要用that引導,不宜用because.What she saw is that the boy was searching for something in the room.The reason why she was late was that her mother was ill.2.主語+look(seem,sound,taste,smell)as if/though+從句 All this was over twenty years age, but it’s as if it was only yesterday.I sounds as if someone is knocking at the door.You look as if you didn’t care.注:從屬連詞if一般不用來引導表語從句,但as if可引導表語從句。
3.主語+look+as 從句:
He looked just as he had looked ten years before.連詞because, why 引導的表語從句。I think it is because you are doing too much.That’s why she got angry with him.在一些表示“建議、勸說、命令”的名詞后面的表語從句中,謂語動詞用虛擬語氣,形式為(should)+動詞原形。常見的詞有:advice, suggestion, order, proposal, plan, idea, opinion, view等。
My suggestion is that we(should)start early tomorrow.His proposal was that they(should)choose a chairman through election.四、同位語從句Appositive Clauses
同位語從句在復合句中作同位語,一般對主句中的抽象名詞起說明和解釋的作用。這些抽象名詞有:fact, fear, belief, evidence,idea, news, doubt,proof, promise, reason, rumor, hope, truth, message, conclusion等。這類同位語從句意義完整,不缺少句子成分,常用that引導(不用which),that在從句中不充當任何成分。
The news that our football team had defeated the rival team made the fans wild with joy.There is rumor that boy is the illegitimate son of the prince.連接代詞who, what引導的同位語從句。
The question who should do the work requires consideration.I have no idea what he is doing now.副詞(how, when, where)和從屬連詞(whether)引導的同位語從句。You have no idea how worried I was when I heard that you had an accident.I have no idea when I can keep up with my classmates.We haven’t yet settled the question where we are going to spend our summer vacation.I have no idea whether he’ll come or not.同位語從句與其中心詞可被謂語動詞等其他成分分隔,此時要能分清句子結構。The thought came to him that the enemy maybe had fled the city.一些表示“建議、命令、要求”的名詞如 advice, suggestion, request, motion, proposal, order, recommendation等后所跟的同位語從句中,謂語動詞用虛擬語氣(should)+動詞原形表示。Could you agree to our request that this(should)be setteld as soon as possible? What do you think of her proposal that we(should)make a play about this story? 同位語從句與定語從句的區別
1.同位語從句前面的名詞只能是上述一些特定的名詞,而定語從句的先行詞可以是名詞、代詞、主句的一部分或是整個主句。
We are not looking into the question whether he is worth trusting.(同)Our team has won the game, which made us very happy.(定)
2.同位語從句與其前的名詞之間在邏輯上“主系表”結構的關系,而定語從句與其先行詞之間是修飾與限定的關系。
We were delighted at the news that our Women’s Volleyball Team had won.——The news is that our Women’s Volleyball Team had won.The team that has won the game is China’s Women’s Volleyball Team.3.That引導定語從句時,在從句中一般作主語或賓語(指物時還可以用which代替),并且作賓語時常常省略;that引導同位語從句時,僅起連接作用,不充當任何成分,但不能省略,也不能用which來代替。
The news that Mr.Li will be our new English teacher is true.(同)The news(that)he told me yesterday is true.(定)
4.有些引導詞如how, whether可以引導同位語從句,但不能引導定語從句。That question whether we need it has not been considered.I have no idea how I can please my boss.五、賓語從句Object Clauses 1.主語+謂語+that從句
The boy dreamed that he was flying to the moon.1.1 常用于這種結構的動詞有很多:say, think, wish, hope, suppose, see, believe, agree, admit, deny, expect, explain, feel, dream, hear, declare, imagine, wonder, know, mean, notice, prefer, report?
1.2 在表示請求、命令、建議的動詞后的賓語從句要用虛擬語氣,常見的有:command, demand, desire, insist, order, propose, recommend, request, require, suggest.He proposed that we(should)set a dead line for the complement of the plan.賓語從句
2.主語+謂語+wh-從句
We must find out who did all this.You may take what you want.此結構的賓語從句,實際上是一個陳述句語序的特殊疑問句,沒有助動詞。常用于這種結構的動詞有:see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover,understand, inform, advise? 3.主語+謂語+whether(if)+從句
I want to know whether(if)he will join us this afternoon.I doubt whether he will succeed.I don’t know if you can help me.此結構的賓語從句相當于whether(if是否)+陳述句語序的一般疑問句,沒有助動詞。注意:if 和whether引導的賓語從句一般可以互換,但whether常與or not連用,if 一般不與or not 連用。
I wonder whether it is true or not.4.主語+be+表語形容詞+從句
I am afraid that we are going to miss the train.I am not sure whether(if)they are doing their best.在該結構中,從句作形容詞賓語,有的語法書認為是狀語從句。用于這種結構的形容詞有:afraid, angry, amazed, anxious, glad, happy, pleased, sad, satisfied, sure, surprised, ashamed, astonished, certain, delighted, disappointed… 5.介詞賓語從句,賓語從句也可用做介詞的賓語。I walked over to where she sat.There is disagreement among economists about what money is and how money is measure.He laughed at what they said.a.連詞that引導的名詞性從句很少作介詞的賓語,只用在except, but, in后。其他一些介詞的賓語從句如果由連詞that引導,則需用it先行一步,作形式賓語。
He is a good student except that he is careless.I know nothing about him except that he is from the south.You may rely on it that I shall help you.b.介詞賓語不可以用which來引導,而要用what來引導。Are you sorry for what you’ve done?
C.作介詞賓語時,只能用whether, 不能用if.Everything depends on whether we have enough experience.D.如果賓語從句后還有賓語補足語,即帶有復合賓語時,則用it作形式賓語,而將賓語從句后置。
We thought it strange that Xiao Wang did not come yesterday.He has made it clear that he will not give in.在使用賓語從句時應注意時態呼應
A.如果主句是一般現在時、一般將來時或祈使句時,從句謂語動詞可以用任何所需要的時態。
He says his father is/was a teacher.I’m sure that you will succeed.B.主句謂語動詞是過去時態,從句謂語動詞一般須用過去時。用什么樣具休的時態就要依從句的需要而定。I thought he studied hard.He said he was watching TV.They didn’t know when they would go to Beijing.She said she had finished the work.C.從句如果與某一具體的過去時間狀語連用,盡管其謂語動作發生在主句謂語動作之前,仍用一般過去時。
She told me that her father died in 1991.D.從句所說明的是一般真理或客觀事實,即使主句用過去時,從句仍用一般現在時。The teacher told the students that the computer is a wonderful machine.
第二篇:名詞性從句教案
名詞性從句包括:
主語從句
表語從句
賓語從句
同位語從句
? The question is who can complete the difficult task.? He has no idea what a remarkable woman Mary is.? That she was able to come made us very happy.? He objected that it was impossible.一、主語從句
1、主語從句在復合句中作主句的主語
That she was chosen made us very happy.What caused the accident is a complete mystery.Whoever comes to the party will receive a present.【注】 “that”在主語從句中不作任何成分,但放在句首時不能省略。
2、問:怎么才能 that 不放在句首呢?
答:有時為了使句子結構平衡,避免“頭重腳輕”,常用it作形式主語,而把從句放在后面。
It depends on the climate whether they are going shopping today.試試看:新產品銷售得好不好取決于它的質量和價格。
It作形式主語的幾種結構:
1、It+ be +形容詞+ that從句
It is strange that he knows nothing about it.2、It+ be +名詞+ that從句
It is a pity that they have failed in the match.3、It+動詞+賓語+ that從句
It depends on its quality and price whether a new product sells well.4、It+動詞的被動結構+ that從句
It is still unknown which team will win the match.作文常用句式:
1、It turned out that...結果是?
2、It has been proved that...已經證明?
3、It is well-known that...眾所周知?
4、It must be pointed out that...必須指出?
二、表語從句
1、表語從句在復合句中作主句的表語
The reason is that you don’t trust her.This is where I disagree.例:The reason ____ we didn't trust him is ______ he has often lied. reason 后面的表語從句只能用that 引導, 不能用because 引導, 但reason后面的定語從句可以用why。
2、表語從句不能用if引導,但可用as if引導。例如: He looked as if he was going to cry.三、賓語從句
賓語從句在復合句中作主句的賓語,賓語從
句一般放在動詞、介詞或形容詞后。
She explained that she was late because of the heavy traffic.【注】
① 有時要用it作形式賓語,而把賓語從句放在句子的后面。He has made it clear that he will not give in.①
如do you think/believe/suppose/expect/imagine后接特殊疑問詞引
導的賓語從句,疑問詞要放在句首。
What do you think is going on outside? ③
I/We(don’t)think/believe/suppose/expect/imagine后接賓語從句
時,反義疑問句要與從句中的主語和謂語保持一致。
I don’t suppose he cares,does he? ④ 在賓語從句中,引導詞whether和if基本一樣,但介詞后的賓語
從句多用whether。
It all depends upon whether we can get their cooperation.⑤ 動詞doubt如用于肯定句,其后的賓語從句常用if/whether引導,如用于否定句或疑問句,則賓語從句用that引導。
I doubt if/whether our football team will win the match.I don’t doubt that I can defeat him in the contest.四、同位語從句
在主從復合句中作同位語的從句稱為同位語從句。同位語從句常放在fact, news, idea, truth, hope, problemin, formation 等名詞后面,用以說明該名詞的具體內容。
The news that they had won the game soon spread over the whole school.?
引導同位語從句的關聯詞用that時,不能省略,不能用which替代
1.引導詞that與what的區別
? what從句中作句子成分(主語、賓語、表語等)what=all that/everything that ? that引導的主語從句放在句首時,不能省略
What we can’t get seems better than what we have.That a new teacher will come to teach us geography is true.2.引導詞if和whether的區別
? whether或if均可表示“是否”的情況如下:
引導賓語從句。例如:
I wonder whether/if the news is true or not.? 只能用whether不能用if表示“是否”的情況:
? 在表語從句中。例如:
The question is whether the film is worth seeing.? 在同位語從句中。例如:
The news whether our team has won the match is unknown.Answer my question whether you are coming.? 在主語從句中。例如:
Whether we shall attend the meeting hasn’t been decided yet.如果用it作形式主語,則whether和if都能引導主語從句。
例如:It hasn’t been decided whether/if we shall attend the meeting.? 用于句型“名詞+as to + whether”中。例如:
There is some question as to whether the public should be told about the accident.? 后面直接跟動詞不定式時。例如:
He doesn’t know whether to stay or not.? 后面緊接or not時。例如:
We didn't know whether or not she was ready.? 用if會引起歧義時。例如:
Please let me know if you like it.該句有兩個意思 “請告訴我你是否喜歡”或 “如果你喜歡,請告 訴我”用了 whether就可以避免歧義。3.引導詞who與whoever的區別
whoever引導名詞性從句時,相當于anyone who或those who,它
既是從句的主語,又是主句的主語。而who只作從句的主語,它
引導的從句才是主句的主語。
Whoever has helped to save the drowning girl is worth praising.Who will be elected president doesn’t make much difference to me.4.引導詞what與whatever的區別
whatever引導名詞性從句時,與what差不多,只是語氣上更強
些,有“任何一切??”之意。
? This is exactly what I want.? It is generally considered unwise to give a child whatever he or she wants.5.同位語從句與定語從句的區別
同位語從句本身完整,定語從句不完整,因此其前的名詞在定語從句中通常作主語、賓語或表語等成分。I made a promise that if anyone set me free I would make him very rich.The mother made a promise that pleased all her children.從結構看,同位語從句常由連接詞that引導,雖在從句中不充 當任何成分,但不可省略。而定語從句中由關系代詞引導,代替先行 詞,并在從句中充當成分(主語或賓語),充當賓語時??墒÷?。6.It 作形式主語和it引導強調句的比較
將 “it is/was?that?”去掉后,句子仍然成立的是強調句,否則是that引導的主語從句 如:
It is a pity that you didn’t go to see the film.It is in the morning that the murder took place.It is John that broke the window.7.whoever與no matter who;whatever與no matter what whoever和whatever既可以引導名詞性從句,也可引導讓步狀語
從句;no matter who和no matter what只引導讓步狀語從句。Whatever(=No matter what)you may think,I’m going ahead with my plans.Take whatever you need and leave me alone.9.名詞性從句中的語氣
(1)在It is necessary/natural/important/strange...+that從句中,從句中的謂語動詞用“should+原形動詞”表虛擬語氣,且should 可省略。
It is necessary that the problem should be settled at once.(2)表示“建議、命令、要求”意義的動詞,后接that從句時,從句
中的謂語動詞要用虛擬語氣,即“should+原形動詞”,且should 可省略。
Bob’s doctor suggests that he(should)rest for a few days.(3)表示“建議、要求、命令、想法”意義的名詞,后接that從句時,從句中的謂語動詞要用虛擬語氣:“should+動詞原形”,should可以省略。
這類名詞有:advice,agreement,command,decision,demand, determination,order,preference,proposal,request,requirement等。This is our only request that this(should)be settled as soon as possible.同樣,如主語是表示“建議、要求、命令、想法”意義的名詞,那么that引導的表語從句中也要用虛擬語氣。
Her suggestion was that they(should)carry on their conversation in French.

新課程與創新教學活動設計大賽
類型: 語法
烏魯木齊外國語學校(第十二中學)
趙麗
名詞性從句學案
一、學習目標
1、本階段大綱要求
近年來,引導名詞性從句的連接代詞及連接副詞為高考必考項目。此語法項目除單選外,完形,短文改錯也考。另外學好它,對閱讀理解是大有好處的。名詞性從句包括主語從句、賓語從句、表語從句和同位語從句
2、本階段重點、難點
1表命令建議order,(命令),suggestion, advice(建議)
的名詞后的表語從句 2.that.whether的區別 3.What, that, which 4:that 的省略
5: whoever引導的名詞性從句 6:because引導的表語從句 7: 名詞性從句皆用陳述語序
二、基礎知識體系、重點內容、題的類型及解題方法等 基礎知識體系
名詞性從句的連接詞按其在從句中所起的作用分為:
1)連接代詞:who(-ever), what(-ever), which(-ever), whom(-ever), whose 2)連接副詞:when, where, why, how 3)連接詞:that, whether, if 連接代詞和連接副詞在從句中充當一定的句子成分,而連接詞在從句中不充當句子成分,只起連接作用
名詞性從句的難點把握
1由whoever/whatever/whichever/whomever引導的名詞性從句 這些詞引導的名詞性從句相當于帶有定語從句的名詞詞組:
whoever=anyone who?“任何??的人”;whomever是whoever的賓格形式 whatever=anything that? “任何??的物”
whichever=any ? that? “任何??的(已知范圍內的或上文提到過的)人或物” that引導的同位語從句與定語從句的區別:
The suggestion that the students(should)have plenty of exercise is very good.The suggestion(that/which)he raised at the meeting is very good.對比發現上句中的that只起連接作用,在從句中不充當任何成分,因此它引導的是同位語從句,其中that不能省略;下句中that不僅起引導作用,同時在從句中還充當了動詞raised的賓語,因此它是定語從句,此時that可用which代替,又因其在定語從句中充當賓語,故又可省略。
2.名詞性從句中的what和that what和that的選用一直是學生學習的一個難點,正確選擇的關鍵是看該從句結構是否相對完整、是否缺少主語、賓語或表語等成分而定。he said at the meeting surprised everybody present.That he said nothing at the meeting surprised everybody present.The problem is what we should do to protect the ear What th.The fact is that we should do something to protect the earth.3.名詞性從句中的whether和if 在主語從句、表語從句和同位語從句中遇“是否”句用whether引導而不用if;在賓語從句中whether和if??蓳Q用。4.名詞性從句中的虛擬語氣
表示“堅持、命令、建議或要求”等詞義出現時,不管是在哪一種從句中,常用虛擬語氣,從句中的謂語動詞形式為(should)+ 動詞原形,其中should可省略。常用詞有insist, suggest, order, demand等。三. 教學步驟。1.復習句型結構。
帶領學生復習一下英語當中的五種簡單句型結構以及主從復合句和并列句,并分清楚他們之間的區別與聯系。
簡單句 S + V
He fled.S + V + O
He didn’t invite me.S + V + P
I am a teacher.S + V + Oo
He promised me a bike as my birthday gift.S + V + O + C
I want you to assist me.簡單句 + 并列連詞
+簡單句
→ 并列句
簡單句 + 并列連詞
+ 主從復合句 → 并列句
2.分辨句子。從以下所給的例題中選出名詞性從句并標明是哪種名詞性從句。
1.The people invited to the ball may dress __ they please.賓從
A.however
B.whatever
C.wherever
D.whenever 2.I can't quite remember __ you started doing the work.賓從

A.what;that
B.that;that
C.what;what
D.that;what 12.He has given us a suggestion ____ we should buy a cottage in the country with the money _________we have saved.同位語從句 定從
A.that , what
B.which, which
C./, which
D.that, /
13.She is pleased with ____ you have given him and all ______you have told him.賓從 定從

B.what, that
C.what, which
D.which, what 14.The reason __ we were late is __ we missed the train.定從 表從
A.why;because
B.why;that
C.why;why
D.that;that 因高三為復習課,所以在復習完基本句型的基礎上作此練習,可以幫助學生進一步去熟悉句型結構,為名詞性從句的掌握打下基礎。三.做題,討論,自我總結。
在這一板塊,先給學生8分鐘時間完成上述題目,之后三人小組討論進行答案分析,然后老師給出正確答案,并對學生自己無法解決的題目進行講解。然后,再次進入討論環節,并進行自我總結,總結出在做名詞性從句當中須注意的點。1.連詞的選用。1.名詞性從句的連接詞按其在從句中所起的作用分為:
1)連接代詞:who(-ever), what(-ever), which(-ever), whom(-ever), whose 2)連接副詞:when, where, why, how 3)連接詞:that, whether, if 連接代詞和連接副詞在從句中充當一定的句子成分,而連接詞在從句中不充當句子成分,只起連接作用
2.名詞性從句需使用陳述語氣。3.連詞if和 whether 的區別。
A 在動詞不定式之前只能用whether。如:
例8 I can’t decide whether to stay.我不能決定是否留下。
B 在whether …… or not 的固定搭配中。如:
例9 I want to know whether it’s good news or not.我想知道是否是好消息。
C 在介詞后,只能用whether。如:
例10 His father is worried about whether he lose his work.他的父親擔心是否會失去工作。
D 賓語從句放在句首表示強調時,只能用whether。如:
例11 Whether they can finish the work on time is still a problem.他們是否能準時完成這項工作還是個問題。
E 用if會引起歧義時,只用whether。如:
例12 Could you tell me if you know the answer ?
5.表命令建議order,(命令),suggestion, advice(建議)
的詞后跟的從句使用虛擬語氣sb should do, should 可以省略 一主張:insist 二命令:order command 三建議:suggest advise recommend 四命令:desire demand require request 6.that引導的同位語從句與定語從句的區別:
The suggestion that the students(should)have plenty of exercise is very good.The suggestion(that/which)he raised at the meeting is very good.對比發現上句中的that只起連接作用,在從句中不充當任何成分,因此它引導的是同位語從句,其中that不能省略;下句中that不僅起引導作用,同時在從句中還充當了動詞raised的賓語,因此它是定語從句,此時that可用which代替,又因其在定語從句中充當賓語,故又可省略。四.鞏固練習。五.課后反思。
因為是高三的學生,所以本節課主要以復習舊知識和鞏固練習為主,而且在整節課中以學生為主體,讓學生去活動以得出最后的知識,效果較好。但是因為有的學生基礎知識較差,在活動中參與性不強。
第四篇:名詞性從句 (教案)
名詞性從句(教案)
在句子中起名詞作用的各種從句,通稱為名詞性從句。根據它們在句子中所起的作用,可分為主語從句、賓語從句、表語從句和同位語從句。
關于what 所引導的名詞從句
what 引導名詞性從句時,可表示兩種意義:一是疑問意義,即“什么”;二是表示“?的東西”、“?事情”,相當于the thing which.Do you know what that is ? This is what he has asked for.主語從句
主語從句可以直接放在主語的位置上;也可以用it 作形式主語,而將從句放在句末。That 引導的主語從句用it 作形式主語的尤為多見。1)That light travels in straight lines is known to all.It is known to all that light travels in straight lines.2)When the plane is to take off has not been announced.It has not been announced when the plane is to take off.用it 作形式主語從句結構
it 引導的主語從句已經形成下面的四種固定用法: 1)It is +名詞+從句 It is a fact that ? 2)It is +形容詞+從句 It is necessary that.? 3)It is +過去分詞+從句 It is said ?
4)It +不及物動詞+從句 It seems that ?
注意:不要將強調句里的強調詞it 和形式主語it 混淆起來。強調句是it is(was)+強調部分+ that(who)?。John bought a toy plane for his son yesterday.It was John that(who)bought a toy plane for his son yesterday.(強調主語)
It was a toy plane that John bought for his son yesterday.(強調賓語)
It was for his son that John bought a toy plane yesterday.(強調目的狀語)
It was yesterday that John bought a toy plane for his son.(強調時間狀語)
賓語從句
1.作動詞的賓語:
Everybody knows that matter takes up space.2.作介詞賓語:
This depends on how hard you work.3.作形容詞賓語:
They are confident that they can do it well.4.要注意的問題:
1)引導詞that的省略:
I think(that)you are right.2)形式賓語it:
He has made it clear that the meeting will not be postponed.3)否定意義的轉移:
think, believe, suppose, expect, I don’t think he has time to play chess with you.I don’t suppose it is the rush hour yet.4)插入語疑問句:
I think that John will arrive at five o’clock.When do you think John will arrive? They said that they had cleaned the classroom.What did they say they had done?
表語從句
1.和be, seem, remain, look聯系動詞連用的表語從句:
My idea is that this plan should be carried out immediately.It looks that it is going to rain.2.Where, why, how 等引導的表語從句: That is why we called off the meeting.This is how we did it.注:主語是reason的表語從句that 要用引導,不要誤用because: The reason(why)he was late was that he missed the bus.(不能用because)
同位語從句
同位語從句用于表示名詞的內容,對其加以解釋。常見的詞有:fact, idea, news, conclusion.The doctor came to the conclusion that the patient was suffering from cancer.The discovery that every heavenly body has gravity was made by Newton.注:同位語從句和定語從句的區別:同位語從句是對前面名詞的補充說明;定語從句則是對前面名詞的修飾和限定。
The idea that one can do the work without thinking is wrong.(同位語從句)
The idea that you put forward at the meeting is wrong.(定語從句)
第五篇:名詞性從句教案
名詞性從句復習教案
一、學習目標 1.本階段大綱要求
近年來,引導名詞性從句的連接代詞及連接副詞為高考必考項目。此語法項目在語法填空中經常出現。另外學好它,對閱讀理解也是大有好處的。
名詞性從句包括主語從句、賓語從句、表語從句和同位語從句
2、本階段重點、難點
(1)表命令建議order,(命令),suggestion, advice(建議)的名詞后的表語從句(2)that和whether的區別(3)what, that, which的用法(4)that 的省略
(5)whoever引導的名詞性從句(6)because引導的表語從句(7)名詞性從句皆用陳述語序
二、基礎知識體系、重點內容、題的類型及解題方法等 1.基礎知識體系
名詞性從句的連接詞按其在從句中所起的作用分為:
1)連接代詞:who(-ever), what(-ever), which(-ever), whom(-ever), whose 2)連接副詞:when, where, why, how 3)連接詞:that, whether, if
連接代詞和連接副詞在從句中充當一定的句子成分,而連接詞在從句中不充當句子成分,只起連接作用 2.名詞性從句的難點把握
1)由whoever/whatever/whichever/whomever引導的名詞性從句
這些詞引導的名詞性從句相當于帶有定語從句的名詞詞組:whoever=anyone 1 who?“任何??的人”;whomever是它的賓格形式whatever=anything that? “任何??的物”
whichever=any ? that? “任何??的(已知范圍內的或上文提到過的)人或物” 2)that引導的同位語從句與定語從句的區別:
The suggestion that the students(should)have plenty of exercise is very good.The suggestion(that/which)he raised at the meeting is very good.對比發現上句中的that只起連接作用,在從句中不充當任何成分,因此它引導的是同位語從句,其中that不能省略;下句中that不僅起引導作用,同時在從句中還充當了動詞raised的賓語,因此它是定語從句,此時that可用which代替,又因其在定語從句中充當賓語,故又可省略。2.名詞性從句中的what和that what和that的選用一直是學生學習的一個難點,正確選擇的關鍵是看該從句結構是否相對完整、是否缺少主語、賓語或表語等成分而定。He said at the meeting surprised everybody present.That he said nothing at the meeting surprised everybody present.The problem is what we should do to protect the earth.The fact is that we should do something to protect the earth.3.名詞性從句中的whether和if 在主語從句、表語從句和同位語從句中遇“是否”句用whether引導而不用if;在賓語從句中whether和if??蓳Q用。4.名詞性從句中的虛擬語氣
表示“堅持、命令、建議或要求”等詞義出現時,不管是在哪一種從句中,常用虛擬語氣,從句中的謂語動詞形式為(should)+ 動詞原形,其中should可省略。常用詞有insist, suggest, order, demand等。
三、典型例題
典型例題分析:
1.____we’ll go comping tomorrow depends on the weather.(96)A If B Whether C That D Where 解析:根據句意“我們明天是否能去野餐得看天氣”,在if和whether中選擇,因為句中引導的是主語從句,而if不能引導主語從句,故答案為B。2.____we can’t get seems better than ____ we have.(96)A What, what B What, that C That, that D That, what 解析:本題正是從學生學習名詞性從句的一個難點what和that的不同用法切入命題。that在引導名詞性從句時只起連接作用,在從句中不作任何成分,從句結構相對完整,具有陳述意義,what在引導從句的同時在從句中充當主語、賓語、表語或定語等句子成分。在本題中,從句中的謂語動詞get和have均為及物動詞,其后都缺了賓語,因此答案為A。
3.I remember ____ this used to be a quiet village.(93)A when B how C where D what 解析:本句從空擋至句末作及物動詞remember的賓語,是一個賓語從句,從句中主語、謂語、表語都有,結構相對完整,因此連接代詞what首先排除;又因句中已提到“這個村莊”、“安靜”,表示地點、狀態的where,how都可排除,正確答案為A,直譯為“我還記得這村莊過去是個安靜的村莊的那個時候,”意譯“我記得這里曾一度是個安靜的村莊?!?/p>
4.Go and get your coat.It’s ____ you left it.(92)A there B where C there where D where there 解析:題中從空擋至結束是一表語從句,there不能引導名詞性從句,故可排除A和D,選項C句意繁復,因此正確答案為B,意思是“它還在你原來所放的地方?!眞here在從句中作時間狀語。
5.No one can be sure ____ in a million years.(91)3 A what man will look like B what will man look like C man will look like what D what look will man like 解析:本題從名詞性從句的詞序排列切入命題,從另一角度考測學生對名詞性從句的句法結構掌握情況。當名詞性從句由一含疑問意義的連接詞引導時,必須把該引導詞放在名詞性從句的開頭,從句中使用主謂結構的陳述句語序,故答案為A。6.It worries her a bit ____ her hair was turning grey.(92)A while B that C if D for 解析:從句子的句法結構看,四個選項均能使題干結構完整,while能引導時間狀語從句和表示前后兩種情況對照的分句,if能引導賓語從句和條件狀語從句,for能引導表示原因的并列句,但如選A、C或D,句首的it所指不明,故A、C、D均不是最佳選項,最佳選項為B,that引導主語從句,it作形式主語放在句首,句意為“她的頭發在變白,這事兒使她有點著急?!?/p>
四、課堂強化訓練 主語從句典型錯誤
1.That she wants to know is which dress she should buy.2.He will give up his job surprises all of us.3.No matter who breaks the law will be punished 4.If the meeting will be held in our school is not known yet.5.That worried her a bit that he couldn’t get in touch with her friend.6.He is said he has gone to America 表語從句典型錯誤:
1.The reason why I was late was because I missed the train.2:.-----I rang you at about ten, but there is no reply.-----Oh, that was probably why I was seeing the doctor.3.The difficult we now meet with is if we can persuade him to tell the truth.4
