10、納如下：一，引導(dǎo)詞1、由that 引導(dǎo)的陳述句性的賓語從句，在很多動(dòng)詞如say, think, wish , hope, see, believe, agree, expect, hear , feel等動(dòng)詞后。連詞that只起連接作用，在從句中不做句子的成分，也無詞匯意義，在口語中常被省略，但在大多數(shù)情況下還是以不省為好，特別是在筆語中。例：I told him that he was wrong.在think, believe, suppose, expect等動(dòng)詞引起的賓語從句中，有時(shí)謂語盡管是否定意義，卻不用否定形式，而將think 等動(dòng)詞變?yōu)榉穸ㄐ问?。例：I dont think y

11、ou are right. (我認(rèn)為你做的不對(duì))在許多帶有復(fù)合賓語的句子中，that引導(dǎo)的賓語從句經(jīng)常移到句子的后面，而用it做形式賓語。例：We think it wrong that he told a lie to everyone (我認(rèn)為他向每一個(gè)人撒謊是錯(cuò)誤的)2、由連詞if、 whether 引導(dǎo)的表示“是否”的賓語從句。Whether, if 在從句中不做句子的成分，一般情況下，whether和if 可以替換。例：I dont know if/whether he will come tomorrow.The teacher asked if/whether we had fi

12、nished the experiment.在介詞后面的賓語從句中不用if引導(dǎo)例：Everything depends on whether we have enough money。賓語從句中有or not時(shí)不用if引導(dǎo).例：I dont know whether the movie star will come or not.和不定式連用作賓語時(shí)不用if引導(dǎo).例：Whether to go there or not has not been decided.3、由wh-引導(dǎo)的賓語從句。連接代詞who, whom, whose, what, which,和連接副詞when, where, w

13、hy, how 等連接的賓語從句，它們?cè)诰渲屑从羞B接從句的作用，又在句中充當(dāng)句子的成分。例：Do you know which film they are talking about? (which做定語)I dont know where he lives. (where 做地點(diǎn)狀語)二，賓語從句的語序，賓語從句從句的語序必須是陳述語序，既連接詞+主語+謂語+其他成分例：I believe that they will come soon.He asked me whether I was a teacher.They wanted to know what they can do for

14、us.三，賓語從句的時(shí)態(tài)。賓語從句的時(shí)態(tài)受主句的限制，既：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)。例: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.3) She says that she has finished her

15、homework already.She said that she had finished her homework already.4) She says that she can sing a song in English.She said that she could sing a song in English.如果賓語從句說的是客觀真理、自然現(xiàn)象或事實(shí)時(shí)，這時(shí)賓語從句要用一般現(xiàn)在時(shí)態(tài)。例：The teacher said that the earth goes round the sun.He told me that Japan is an island country.Co

16、uld you tell me是用來征詢對(duì)方的意見，語氣委婉，并不表示過去。例：Could you tell me when we will visit the History Museum?注意事項(xiàng)：由陳述句變成賓語從句時(shí)，要注意人稱的變化。例：She said: “I have been to England before.”She said that she had been to England before.She asked me: “Do you like maths?”She asked me if I liked maths.賓語從句與簡(jiǎn)單句的交換。由連接代詞和連接副詞引導(dǎo)的

17、賓語從句，如果賓語從句的主語和主句的主語是同一個(gè)人時(shí)，可以用“疑問詞+不定式”做賓語的簡(jiǎn)單句結(jié)構(gòu)。例：I dont know what I should do next.I dont know what to do next.He didntt know where he would live.He didntt know where to live.There be 句型1 there be 結(jié)構(gòu)中的be 是可以運(yùn)用各種時(shí)態(tài)的。 例：There is going to be a meeting tonight.今晚有個(gè)會(huì)議。 There was a knock at the door.有人敲

18、門。 There has been a girl waiting for you.有個(gè)女孩一直在等你。 There will be rain soon.不久天就要下雨了。 2動(dòng)詞be單復(fù)數(shù)形式要跟there be之后的真正的主語一致。并且要根據(jù)就近一致原則來變換be 的單復(fù)數(shù)形式。 如： There is a book on the desk.課桌上有一本書。 How many people are there in the city? 這個(gè)城市里有多少人口。 There is a pen and two books on the desk.課桌上有一個(gè)鋼筆和兩本書。 There are tw

19、o books and a pen on the desk. 課桌上有兩本書和一個(gè)鋼筆。 There are some students and a teacher in the classroom. 在教室里有一些學(xué)生和一位老師。 There is a teacher and some students in the classroom. 在教室里有一位老師和一些學(xué)生。 3 在there be引起的句子結(jié)構(gòu)中，用來修飾主語的不定式主動(dòng)形式和被動(dòng)形式均可。 例：There is no time to lose (= to be lost).時(shí)間緊迫。 There is nothing to s

20、ee (=to be seen).看不見有什么。 There is nothing to do.(=to be done) 無事可做。 二、 結(jié)構(gòu)變形：在there be 結(jié)構(gòu)中還可把be 改變從而使得there be結(jié)構(gòu)有了一些改變具體總結(jié)如下： 1 There used/seem/ happen/appear to be 例：There might be snow at night.晚上可能有雪。 There appeared to be nobody willing to help.看來沒人愿意幫忙。 There used to be a building here.過去這兒有一座樓房。

21、 There happened to be a man walking by.碰巧有個(gè)人在此經(jīng)過。 There doesn't seem to be much hope.好象沒有太大的希望。 2 在there be的 be 前還可以加上各種情態(tài)詞， 例：There must be something wrong.一定有問題。 There ought not to be so many people.不應(yīng)該有這么多的人。 There might still be hope .可能還有點(diǎn)希望。 3 在there be句型中的be還可以換成其他的動(dòng)詞與there連用，這些詞都是表示狀態(tài)的如：

22、live stand exist remain等或用來描寫某事的發(fā)生或某人的到達(dá)如come, appear, enter, follow, occur等。 例：There lived a rich man.這以前住著一個(gè)富翁。 Then there came a knock at the door.然后有人敲門。 Long, long ago, there lived a king.很久很久以前，有一個(gè)國王。 There followed a terrible noise.然后是傳來了可怕的聲音。 Suddenly there entered a strange man.突然進(jìn)來了一個(gè)奇怪的人
