That we will be late is certain. (We will be late.)2.) That he did not come yesterday is a pity. (He did not come yesterday.) (注意) 主語(yǔ)從句的that一定不能省略，而賓語(yǔ)從句中的that可以省略。 Eg. 1.) That we will be late is certain. (主語(yǔ)從句，that不能省略) 2.) I hope (that) we will win the game. (賓語(yǔ)從句，that 可以省略)2. 當(dāng)主語(yǔ)是一般疑問句時(shí)，連接詞是whether(or not) 即： whether(or not) +該一般疑問句的陳述語(yǔ)序(注意)“if” 不能引導(dǎo)主語(yǔ)從句，這要與賓語(yǔ)從句進(jìn)行區(qū)分。Eg. 1.) Whether he will go there is not known. (Will he go there?) 2.) Whether they can finish the job (or not) is not clear. (Can they finish the job?)3. 當(dāng)主語(yǔ)是特殊疑問句時(shí)，連接詞是特殊疑問詞“8W+H” 即：特殊疑問詞“8W+H” +該特殊疑問句的陳述語(yǔ)序 （注：8W指的是what/where/which/who/whom/why/whose/when, H 指的是how）Eg. 1.) What he did yesterday is not known. (What did he do yesterday?)2.) Where he went yesterday is not clear. (Where did he go yesterday?)3.) Which team he liked has not been decided. (Which team did he like?)4.) Who won the game seems certain. (Who won the game?)5.) Whom he met yesterday is not clear. (Whom did he meet yesterday?)6.) Why he was late for the meeting is to be found out. (Why was he late for the meeting?)7.) Whose book this is is not clear. (Whose book is this?)8.) When he will arrive is not known. (When will he arrive?)9.) How we will help the lost boy will be discussed at the meeting. (How will we help the lost boy?) II. (注意一) 主語(yǔ)從句后置! 為了避免主語(yǔ)冗長(zhǎng),句子頭重腳輕,經(jīng)常用it作形式主語(yǔ),主語(yǔ)從句放在后面作真正的主語(yǔ).Eg. 1.) That we will be late is certain.- Its certain that we will be late. 2.) Whether he will go there is not known.- It is not known whether he will go there. 3.) Where he went yesterday is not clear.- It is not clear where he went yesterday. It 作形式主語(yǔ)常用句型：(that 引導(dǎo)的主語(yǔ)從句是真正的主語(yǔ)) It is possible/important/necessary/clear that. Its said/ reported that. 據(jù)說/據(jù)報(bào)道 Its been announced/declared that. 已經(jīng)通知/宣布 It seems/appears/happens that 顯然、明顯、碰巧. Its no wonder that并不奇怪/無疑 （注意二）主語(yǔ)從句中 ，謂語(yǔ)動(dòng)詞一般用單數(shù)。What引導(dǎo)的主語(yǔ)從句，謂語(yǔ)動(dòng)詞根據(jù)表語(yǔ)決定What he needs _is_ that book.What he needs _are_ some books.（注意三）What 與 that 引導(dǎo)主語(yǔ)從句的區(qū)別Eg. (1) What you said yesterday is right. (What did you say yesterday?)(2) That she is still alive is a puzzle. (She is still alive.) 練習(xí)題1. _ he made an important speech at the meeting was true.A. That B. Why C. What D. How 2. _well go camping tomorrow depends on the weather. A If B Whether C That D Where 3._ is known to us all is that America is a developed country. A. Which B. As C. What D. It4. Its known to us all _ a form of energy . A. water is B. that water is C. is water D. that water to 賓語(yǔ)從句 I. 賓語(yǔ)從句: 賓語(yǔ)是個(gè)句子，或者說從句在句中充當(dāng)賓語(yǔ).1. 當(dāng)賓語(yǔ)是陳述句時(shí)，連接詞是that 即： that(可省略)+該陳述句Eg. 1.) I hope (that) he will come tomorrow. (He will come tomorrow.)2.) He guesses (that) this team will win. (This team will win.) (注意) 主語(yǔ)從句的that一定不能省略，而賓語(yǔ)從句中的that可以省略。 Eg. 1.) That we will be late is certain. (主語(yǔ)從句，that不能省略) 2.) I believe (that) we will win the game. (賓語(yǔ)從句，that 可以省略)2. 當(dāng)賓語(yǔ)是一般疑問句時(shí)，連接詞是whether(or not)/if 即： whether(or not)/if +該一般疑問句的陳述語(yǔ)序Eg. 1.) I ask whether/if Tom knows Jack. (Does Tom know Jack?) 2.) I dont know whether/if he came back yesterday. (Did he come back yesterday?)3. 當(dāng)賓語(yǔ)是特殊疑問句時(shí)，連接詞是特殊疑問詞“8W+H” 即：特殊疑問詞“8W+H” +該特殊疑問句的陳述語(yǔ)序 （注：8W-what/where/which/who/whom/why/whose/when, H-how）Eg. 1.) I dont know what he did yesterday. (What did he do yesterday?)2.) He wants to know where he went yesterday. (Where did he go yesterday?)3.) He didnt tell me which team he liked. (Which team did he like?)4.) We want to know who won the game at last. (Who won the game?)5.) His mom asked whom he met yesterday. (Whom did he meet yesterday?)6.) He didnt find out why he was late for the meeting. (Why was he late for the meeting?)7.) I am not sure whose book this is. (Whose book is this?)8.) They ask me when he will arrive. (When will he arrive?)9) We have discussed how we will help the lost boy. (How will we help the lost boy?) II. (注意一) 當(dāng)主句的謂語(yǔ)動(dòng)詞是command/demand/insist/order/require/suggest等表示要求或建議的動(dòng)詞時(shí)，從句謂語(yǔ)動(dòng)詞用（should）+動(dòng)詞原詞，should 可以省略。eg （1）She required (that) he (should) go back home right now. She required (that) he go back home right now. （2）I suggested (that) he (should) ask his teacher for help. I suggested (that) he ask his teacher for help. （注意二）當(dāng)主句中believe/expect/suppose/think等作謂語(yǔ)動(dòng)詞時(shí)，否定要前移。 Eg. I dont think that he will come tomorrow. (He wont come tomorrow.) He doesnt believe that it is true. (It is not true.) （注意三）賓語(yǔ)從句的語(yǔ)序賓語(yǔ)從句從句的語(yǔ)序必須是陳述語(yǔ)序，即連接詞+主語(yǔ)+謂語(yǔ)+其他成分eg. I believe that they will come soon. He asked me whether I was a teacher. They wanted to know what they can do for us.（注意四）賓語(yǔ)從句的時(shí)態(tài)賓語(yǔ)從句的時(shí)態(tài)受主句的限制，即：主句是一般現(xiàn)在時(shí)態(tài)，從句根據(jù)實(shí)際情況而定。主句是一般過去時(shí)態(tài)，從句用相應(yīng)的過去的時(shí)態(tài)。如果從句的動(dòng)作發(fā)生在主句之前，則從句要用過去完成時(shí)態(tài)。eg. 1)She says that she is a student. She said that she was a student. 2)She says that she will fly to Japan in a week. She said that she would fly to Japan in a week.（注意五）由whether或特殊疑問詞8W+H引導(dǎo)的賓語(yǔ)從句(也就是第二、第三種情況時(shí))，如果賓語(yǔ)從句的主語(yǔ)和主句的主語(yǔ)是同一對(duì)象，可以用“疑問詞+不定式”做賓語(yǔ)的簡(jiǎn)單句結(jié)構(gòu)。eg. I dont know what I should do next. I dont know what to do next. He didnt know where he would live. He didnt know where to live. He wasnt clear which way he should go to reach the bank. =He wasnt clear which way to go to reach the bank.（注意七）含有賓語(yǔ)補(bǔ)足語(yǔ)時(shí)，若賓語(yǔ)是個(gè)句子，賓語(yǔ)通常用形式賓語(yǔ)it 代替，真正的賓語(yǔ)放在賓語(yǔ)補(bǔ)足語(yǔ)之后。 Eg. 1) We think it wonderful that we will go on a trip this weekend. (賓語(yǔ)是陳述句) 2) I think it uncertain whether we will win the game. （賓語(yǔ)是一般疑問句） 3) We hope it discussed how we will solve the problem. (賓語(yǔ)是特殊疑問句)練習(xí)題1。 Do you know _ the Capital Museum?

He admitted the fact that he had stolen the wallet. (注意) that引導(dǎo)同位語(yǔ)從句時(shí)只是中心詞和同位語(yǔ)從句之間的橋梁而已，無任何意義，也不充當(dāng)任何成分，但that 不可以省略（二）. 當(dāng)同位語(yǔ)從句是一般疑問句時(shí)，連接詞是whether(or not) 即： whether(or not) +該一般疑問句的陳述語(yǔ)序(注意) 此處不能用if. 1.) He hasnt made the decision whether he will go there. (decision 的內(nèi)容是 Will he go there?) 2.) They have not come to an agreement whether he should take part in this game. (agreement 的內(nèi)容是 Should he take part in this game?) （三）. 當(dāng)同位語(yǔ)從句是特殊疑問句時(shí)，連接詞是特殊疑問詞“8W+H” 即：特殊疑問詞“8W+H” +該特殊疑問句的陳述語(yǔ)序 （注：8W指的是what/where/which/who/whom/why/whose/when, H 指的是how）1.) I have no idea what the boy is doing in the next room now.2.) We havent yet settled the question where we are going to spend our summer vacation this year.3.) We have not come to a conclusion which team is the best. 4.) The question who should do the work is being discussed at the meeting.5.) The doubt whom he talked with yesterday is important to the case(案件). 6.) The doubt why he did not come yesterday is important to the case(案件). 7.) The problem whose money this is has not been solved. 8.) I have no suggestion when he will be back9.) The thought came to me how I can solve this problem. 2. that 引導(dǎo)的同位語(yǔ)從句和定語(yǔ)從句的區(qū)別1)意義不同：that 引導(dǎo)的同位語(yǔ)從句是用來進(jìn)一步說明前面名詞的內(nèi)容，是解釋中心詞；而that 引導(dǎo)的定語(yǔ)從句用來修飾、限定前面的先行詞，是修飾中心詞（先行詞）。Eg. The news that our team has won the final match is true. The news that he told us is true.分析中that引導(dǎo)同位語(yǔ)從句，解釋說明“news”的內(nèi)容：我們隊(duì)取得了決賽勝利。 中that引導(dǎo)定語(yǔ)從句，對(duì)“news”加以限定：是他告訴我們的，而非來自其他渠道，起修飾作用。2) that功能不同：that引導(dǎo)同位語(yǔ)從句時(shí)是一個(gè)純連詞，只是中心詞和同位語(yǔ)從句之間的連接詞，不充當(dāng)任何成分；而that引導(dǎo)定語(yǔ)從句時(shí)，是關(guān)系代詞，不僅起連接作用，而且還指代先行詞并在從句中充當(dāng)主語(yǔ)、賓語(yǔ)等成分。Eg. Dad made a promise that he would buy me a CD player if I passed the English test. . Dad made a promise that excited all his children.分析 中 that引導(dǎo) 同位語(yǔ)從句，其中that無詞義，也不充當(dāng)任何成分；.中that引導(dǎo)定語(yǔ)從句，that指代promise，又在從句中充當(dāng)主語(yǔ)，且that可以用which替換。3)that可否省略：that引導(dǎo)同位語(yǔ)從句時(shí)，不可省略。在引導(dǎo)定語(yǔ)從句時(shí)，若在從句中作賓語(yǔ)，可以省略，若作主語(yǔ)則不可以省略。Eg.The news that our team has won the final match is true. The news (that) he told us is true. The news that is from this newspaper is true. 分析 中 that引導(dǎo) 同位語(yǔ)從句，不能省略。.中that引導(dǎo)定語(yǔ)從句，that指代news，在從句中充當(dāng)賓語(yǔ)， that可以用which替換，也可以省略。中that 也是引導(dǎo)定語(yǔ)從句，that 指代news, 在從句中充當(dāng)主語(yǔ)，that 可以用which 替換，但that 不能省略。3. 有時(shí)同位語(yǔ)從句可以不緊跟在被解釋說明的名詞后面，而被別的詞隔開。 定語(yǔ)從句有時(shí)也可以不緊跟在被修飾的先行詞后面，而被別的詞隔開。Eg. The news is true that a new teacher will come tomorrow to teach us English. A new teacher will come tomorrow who will teach us English. （定語(yǔ)從句who will teach you English 修飾a new teacher, 被will come tomorrow 隔開，定語(yǔ)從句與先行詞分離） 練習(xí)題1). They expressed the hope _ they would come over to China soon.2) The fact _ he didnt see Tom this morning is true.3) Word has come _ some American guests will come to our college for a visit next week.4). He cant answer the question _ he got the money from his home yesterday. 5). Do you have any idea _ is actually going on in the classroom? 6). The problem _ we should have the meeting in the hall now must be decided at once.2. The suggestion _ the monitor gave is good. The suggestion _ we will have a trip on the Great Wall this week is good. A. that B. C. which D. where 定語(yǔ)從句 定語(yǔ)從句：定語(yǔ)是個(gè)句子,也就是一個(gè)句子作定語(yǔ)從屬于主句。定語(yǔ)一般是由形容詞充當(dāng)，所以定語(yǔ)從句又稱作形容詞從句。另外，定語(yǔ)從句是由關(guān)系代詞或關(guān)系副詞引導(dǎo)的，故又稱作關(guān)系從句。關(guān)系代詞和關(guān)系副詞又統(tǒng)稱為引導(dǎo)詞。 區(qū)別：漢語(yǔ)中，定語(yǔ)只能放在名詞前面，而英語(yǔ)中，定語(yǔ)既可以放在名詞前（形容詞修飾名詞），也可以放在名詞后面（定語(yǔ)從句修飾名詞）。被修飾的中心詞叫作先行詞。Eg.（1） He is a clever boy. He is a boy who is clever. (a boy 是中心詞或者先行詞，who is clever 是修飾a boy 的定語(yǔ)從句，who 是關(guān)系代詞，替代先行詞 a boy)拆成兩個(gè)句子：He is a boy. （主干）This boy is clever. （定語(yǔ)） 定語(yǔ)從句一般要緊跟在中心詞（先行詞）的后面，即：He is a boy (this boy is clever). 去掉定語(yǔ)從句中與中心詞（先行詞）重復(fù)的部分，即this boy, 把它替換成指人的關(guān)系代詞who, 即 He is a boy who is clever. （2）他是一個(gè)我們喜歡的男孩。拆成兩個(gè)句子：他是一個(gè)男孩。He is a boy. (主干) 我們喜歡這個(gè)男孩。We like this boy. (定語(yǔ))定語(yǔ)從句在中心詞（先行詞）的后面，即：He is a boy (we like this boy).去掉定語(yǔ)從句中與中心詞（先行詞）重復(fù)的部分，即this boy, 把它替換成指人的關(guān)系代詞who, 即 He is a boy (we like who). 但是，定語(yǔ)從句中，關(guān)系代詞要緊跟中心詞（先行詞）后面，所以who 要緊跟在a boy 后面，即：He is a boy who we like. 一.關(guān)系代詞引導(dǎo)的定語(yǔ)從句1.關(guān)系代詞代替前面的先行詞，關(guān)系代詞/先行詞都在定語(yǔ)從句中充當(dāng)句子成分，可以作主語(yǔ)、賓語(yǔ)、定語(yǔ)等。常見的關(guān)系代詞有： that, which, who, whom, whose。that既可指人又可指物，在定語(yǔ)從句中作主語(yǔ)或賓語(yǔ)，作賓語(yǔ)時(shí)還可省略。which代替物，在定語(yǔ)從句中作主語(yǔ)或賓語(yǔ)，作賓語(yǔ)時(shí)還可省略who代替人，在定語(yǔ)從句中作主語(yǔ)或賓語(yǔ)，作賓語(yǔ)時(shí)還可省略。whom代替人，在定語(yǔ)從句中作賓語(yǔ)，還可省略。whose既可指人又可指物，是所有格，在定語(yǔ)從句作定語(yǔ)。（一）. 先行詞是人，1) 在定語(yǔ)從句中充當(dāng)主語(yǔ)時(shí)：that/whoEg. An architect is a person that/who designs buildings. I will never forget the teacher that/who taught us chemistry in my middle school. 2) 在定語(yǔ)從句中充當(dāng)賓語(yǔ)時(shí)：that/who/whom/ (關(guān)系代詞省略) Eg. Do you know the man that/who/whom/ we met in the school library yesterday? This is the student that/who/whom/ my father taught ten years ago. 3) 在定語(yǔ)從句中充當(dāng)定語(yǔ)(所有格)時(shí)：whose/ of whom Eg.The girl whose father is an engineer studies abroad. 其父是一位工程師的那個(gè)女孩在國(guó)外留學(xué)。 The girl the father of whom is an engineer studies abroad. A child whose parents are dead is called an orphan. A child the parents of whom are dead is called an orphan. （二）. 先行詞是物，1) 在定語(yǔ)從句中充當(dāng)主語(yǔ)時(shí)：that/which Eg. Tom works in a factory that/which makes watches. I do not like stories that/which have unhappy endings. 2) 在定語(yǔ)從句中充當(dāng)賓語(yǔ)時(shí)：that/which/ (關(guān)系代詞省略) Eg. This is the book that/which/ you want to buy? The letter that/which/ I received yesterday is very important. 3)在定語(yǔ)從句中充當(dāng)定語(yǔ)(所有格)時(shí)：whose /(whichs) / of which Eg. Do you know the hotel whose window we can see here? ( = Do you know the hotel whichs window we can see here?) =Do you know the hotel the window of which we can see here? （關(guān)系代詞whose指代先行詞hotel, 也可以用of which, whose window=the window of which, 意思是: the window of the hotel。） He can repair the desk whose leg is broken. (= He can repair the desk whichs leg is broken.) =He can repair the desk the leg of which is broken. （三）. 先行詞既有人，又有物，1)在定語(yǔ)從句中充當(dāng)主語(yǔ)時(shí)：that Eg. The time, place and persons that are mentioned in the story are very important. He was watching the children and parcels that filled the car. 他正望著塞滿車的孩子和包裹。 2)在定語(yǔ)從句中充當(dāng)賓語(yǔ)時(shí)：that / (關(guān)系代詞省略) Eg. The time, place and persons that/ the writer mentioned in the story are very important. （注 意） 1.當(dāng)介詞與關(guān)系代詞緊密相連時(shí)，即介詞后面的關(guān)系代詞用whom（指人時(shí)）或者which(指物時(shí))， 而不用who（指人時(shí)）和that（指人或物時(shí)）。例如： (1) The man to whom our headmaster talked just now is our English teacher. 我們校長(zhǎng)剛才與他談話的那個(gè)人是我們的英語(yǔ)老師。注意：介詞與關(guān)系代詞不是緊密相連時(shí)，或者說介詞放在句子后面時(shí)，這時(shí)可以用who，也可用that，還可以省略關(guān)系代詞。因此，上面的這句話還可以有如下四種說法： The man whom our headmaster talked to just now is our English teacher. The man who our headmaster talked to just now is our English teacher. The man that our headmaster talked to just now is our English teacher. The man our headmaster talked to just now is our English teacher. 第4句簡(jiǎn)潔、自然，所以口語(yǔ)中用得最多。 (2)This is the book for which you asked. 注意：介詞與關(guān)系代詞不是緊密相連時(shí)，或者說介詞放在句子后面時(shí)，這時(shí)可以用which，也可用that，還可以省略關(guān)系代詞。因此，上面的這句話還可以有如下三種說法： This is the book which you asked for. This is the book that you asked for. This is the book you asked for. 2. 關(guān)系代詞which 可以指代前面的整個(gè)句子。 關(guān)系代詞as 也可以指代前面的整個(gè)句子。Eg. He comes from America, which I know from his accent. (which 在定語(yǔ)從句中作know的賓語(yǔ)，其先行詞是前面的整個(gè)句子he comes from America.) = He comes from America, as I know from his accent. 練 習(xí) 題1.Isthisthefactory_youvisitedtheotherday?A.that B.Which C.

C.for which D.that 二、關(guān)系副詞引導(dǎo)的定語(yǔ)從句常用的關(guān)系副詞只有三個(gè)：when,where,why，關(guān)系副詞在定語(yǔ)從句中作狀語(yǔ),在定語(yǔ)從句中充當(dāng)時(shí)間、地點(diǎn)和原因狀語(yǔ)。（一）關(guān)系副詞when的用法 關(guān)系副詞when代替的先行詞表示的是時(shí)間，when在定語(yǔ)從句作時(shí)間狀語(yǔ)。Eg. I will never forget those days _we lived together. = I will never forget those days which we lived together in. = I will never forget those days in which we lived together. = I will never forget those days when we lived together. (時(shí)間the time) in/on/during which. = (時(shí)間the time) when.(區(qū)分) I will never forget those days _ we spent together. （二）關(guān)系副詞where的用法 關(guān)系副詞where代替的先行詞表示的是地點(diǎn)，where在定語(yǔ)從句作地點(diǎn)狀語(yǔ)。Eg. This is the place _ Li Bai once lived. =This is the place which Li Bai once lived in. =This is the place in which Li Bai once lived. = This is the place where Li Bai once lived. =This is where LiBai once lived. (地點(diǎn)the place) in/at which. = (地點(diǎn)the place) where.(區(qū)分) This is the place _ Li Bai once visited. （三）關(guān)系副詞why的用法 關(guān)系副詞why代替的先行詞表示的是原因，why在定語(yǔ)從句作原因狀語(yǔ)。Eg.
