高中英語語法基礎學習知識點
單詞和語法是學習英語的重中之重，也是最難的地方。隨着不同的英語學習時期，需要掌握的語法知識也會越來越多。進入高中以後，同學們逐漸會感覺到學習的壓力，下面，小編給大家整理了高中需要掌握的語法知識點，大家可以作爲學習的參考。
Unit1~2.直接引語變間接引語
一、如何變人稱;
下面有一句順口溜"一隨主。二隨賓，第三人稱不更新"。"一隨主"是指在直接引語變間接引語時，如果從句中的主語是第一人稱或被第一人稱所修飾。從句中的人稱要按照主句中主語的人稱變化如：
She said. "My brother wants to go with me. "→She said her brother wanted to go with her.
"二隨賓"是指直接引語變間接引語時，若從句中的主語及賓語是第二人稱。或被第二人你所修飾。從句中的人稱要跟引號外的主句的賓語一致。如果引號外的主句沒有賓語。也可以用第一人稱，如：
He said to Kate. "How is your sister now?"→He asked Kate how her sister was then。
"第三人稱不更新"是指直接引語變間接引語時。如果從句中的主語及賓語是第三人稱或被第三人稱所修飾從句中的人稱一般不需要變化如：
Mr Smith said。 "Jack is a good worker。"→Mr Smith said Jack was a good worker。
二、如何變時態：
直接引語在改爲間接引語時、時態需要做相應的調整。
現在時它需改爲過去時態;過去時態改爲完成時;過去完成時則保留原來的時態。如：
1)She said. "I have lost a pen."→She said she had lost a pen
2)She said. "We hope so."→She said they hoped so.
3) She said. "He will go to see his friend。"→She said he would go to see his friend。
但要注意在以下幾種情況下。在直接引語變爲間接引語時，時態一般不變化。
①直接引語是客觀真理。
"The earth moves around the sun and the moon moves around the earth, the teacher told me. → The teacher told me the earth moves around the sun and the moon moves around the earth。
②直接引語是過去進行時，時態不變。如：
Jack said. "John, where were you going when I met you in the street?"→Jack asked John where he was going when he met him in the street。
③直接引語中有具體的過去某年、某月、某日作狀語，變爲間接引語時，時態不變。如：
Xiao Wang said. "I was born on April 2l, 1980。" →Xiao Wang said he was born on April 20, 1980。
④直接引語如果是一般現在時。表示一種反覆出現或習慣性的動作，變間接引語，時態不變。如：
He said, "I get up at six every morning。" →He said he gets up at six every morning。
⑤如果直接引語中的情態動詞沒有過去時的形式(例：ought to， had better, used to)和已經是過去時的形式時，(例：could, should, would, might)不再變。如：
Peter said. "You had better come have today。" →Peter said I had better go there that day。
三、如何變狀語：
直接引語變間接引語，狀語變化有其內在規津，時間狀語由"現在"改爲"原來"(例：now變爲then, yesterday。變爲 the day before)地點狀語，尤其表示方向性的，或用指示代詞修飾的狀語，由"此"改爲"彼"(例：this 改爲that),如：
He said, "These books are mine." →He said those books were his.
四、如何變句型：
①直接引語如果是陳述句，間接引語應改爲由that引導的賓語從句。如：She said, "Our bus will arrive in five minutes."→She said that their bus would arrive in five minutes.
②直接引語如果是反意疑問句，選擇疑問句或一般疑問句，間接引語應改爲由whether或if引導的賓語從句.如：He said, "Can you swim, John?" →He asked John if he could swim.
"You have finished the homework, haven't you?" my mother asked. →My mother asked me whether I had finished the homework.
"Do you go to school by bus or by bike?" →He asked me if I went to school by bus or by bike.
③直接引語如果是特殊問句，間接引語應該改爲由疑問代詞或疑問副詞引導的賓語從句(賓語從句必須用陳述句語序)。
She asked me, "When do they have their dinner?"→ She asked me when they had their dinner.
④直接引語如果是祈使句，間接引語應改爲"tell(ask, order, beg等) sb (not) to do sth."句型。如：
"Don't make any noise," she said to the children. →She told (ordered) the children not to make any noise. "Bring me a cup of tea, please," said she.→She asked him to bring her a cup of tea.
⑤直接引語如果是以"Let's"開頭的祈使句，變爲間接引語時，通常用"suggest +動句詞(或從句)。"如：
He said, "Let's go to the film." →He suggested going to the film.或He suggested that they should go to see the film.
引述別人的話有兩種方式：一是使用引號引出人家的原話，這叫做直接引語;一是用自己的話把人家的話轉述出來，這叫做間接引語。例如：
John said, "I'm going to London with my father."
約翰說："我要和父親到倫敦去。"(引號內是直接引語)
John said that he was going to London with his father.
約翰說，他要和他父親去倫敦。(賓語從句是間接引語)
由直接引語變爲間接引語，分以下情況：
1. 直接引語是陳述句時
間接引語爲that引導的賓語從句(口語中that可以省略)，主句的引述動詞主要有say ,tell, repeat, explain, think等。
He said , "You are younger than I."-'He said (that ) I was younger than him.
2.直接引語是疑問句時
間接引語爲陳述語序：主句的謂語動詞say 改爲ask,或改爲wonder, do not know, want to know, be not sure, be puzzled等。
(1) 一般疑問句或反意疑問句變爲if (whether)引導的賓語從句。
She said, "Do you often come here to read newspapers?"
→She asked me if (或whether)I often went there to read newspapers.
She asked me , "You have seen the film, haven't you?"
→She asked me whether(或if )I had seen the film.
(2) 選擇疑問句變爲 賓語從句。
I asked him, "Will you stay at home or go to a film tonight?"
→I asked him whether he would stay at home or go to a film that night.
(3)特殊疑問句變爲由原來的疑問詞引導的賓語從句。
He asked , "Where do you live?"
→He asked me where I lived.
3.直接引語是祈使句時
間接引語爲不定式，作ask , tell, beg, order, warn, advise等動詞的賓語補足語(don't 變爲not ).
The teacher said to the boy, "Open the window."→The teacher told the boy to open the window.
His father said to him , "Don't leave the door open."→His father told him not to leave the door open.[注意](1) 有些表示建議、提議、勸告或要求的祈使句，可以用suggest ,insist等動詞 加以轉述。例如：
He said, "Let's go to the theatre."
→He suggested (our )going to the theatre.或He suggested that we(should) go to the theatre.
(2) "Would you mind opening the window?" he asked.
→He asked me to open the window.
"Why don't you take a walk after supper?" he asked .
→he advised me to take a walk after supper.
"Shall we listen to the music?" he asked.
→He suggested listening to the music.
4.直接引語是感嘆句時
間接引語爲what 或how 引導，也可以用that 引導。
She said, "What a lovely day it is !"
→She said what a lovely day it was .或She said that it was a lovely day.
5.如果主句謂語動詞爲各種現在時或一般將來時，則間接引語中的動詞仍保持直接引語原來時態。如果主句謂語動詞爲過去時，間接引語中的動詞時態按下列變化：
(1) 一般現在時變爲一般過去時
(2) 現在進行時變爲過去進行時
(3) 一般將來時變爲過去將來時
(4) 現在完成時變爲過去完成時
(5) 一般過去時變爲過去完成時
(6) 過去完成時不變，仍爲過去完成時[注意](1) 如果直接引語是表示客觀真理時，變爲間接引語，一般現在時不改爲一般過去時。如：
The teacher said "The earth goes round the sun."
→The teacher said that the earth goes round the sun.
(2) 如果直接引語中有明確表示過時間的狀語，變爲間接引語時，一般過去時不改爲過去完成時。如：
He said to me, "I was born in 1973."
→He told me that he was born in 1973.
(3)如果直接引語所述事實在當時和目前同樣生效，變爲間接賓語時，一般現在時不改爲一般過去時。如：
He said, "I'm a boy, not a girl."
→He said that he is a boy ,not a girl.
(4)如果直接引語中的謂語動詞表示一種反覆出現或習慣動作，在變爲間接引時，一般現在時不改爲一般過去時。如：
The girl said, "I get up at six every morning."
→The girl said that she gets up at six every morning.
(5)如果直接引語中含有since, when, while 引導的表示過去時間的狀語從句，在變爲間接引語時，只改變主句中的謂語動詞，從句的一般過去時則不變。如：
He said to me, "I have taught English since he came here ."
→He told me that he had taught English since he came here.
(6)如果直接引語中含有情態動詞 must, need, had better以及情態動詞的過去式could, might, should, would,在變爲間接引語時，這些情態動詞沒有時態的改變。例如：
The teacher said to me . "You must pay more attention to your pronunciation."
→The teacher told me that I must (have to ) pay more attention to my pronunciation.
He said , "I could swim when I was only six ."
→He said that he could swim when he was only six.

2) 表示交通方式、行程安排的動詞，例如 fly, walk, ride, drive, take (a bus, a taxi)等的現在進行時也經常用於表示將來(注意: 英語中一些表 "狀態和感官"的動詞通常不用於進行時【見下表】)

Unit 4~5.定語從句
1. 定語從句的結構及理解2. 定語從句的關係詞的使用3. 定語從句的簡化表達
知識總結歸納
(一)定語從句的結構：在複合句中，修飾某個名詞或代詞的句子(做這個名詞或代詞的定語)叫定語從
句，定語從句一般放在被修飾的名詞或代詞後面，被修飾的名詞或代詞叫做定語從句的先行詞，它與定語
從句之間要有一個詞連接，這個詞指代先行詞的內容叫做關係詞(關係代詞或關係副詞：that, which, who,
whose, when, where, why)。先行詞在定語從句中充當主語，賓語，時間，地點，原因狀語。
結構：先行詞+關係詞+定語從句。
1. Thereshesaw a wall of water that was quicklyadvancing towards her.
2. In Japan, someone who sees anotherperson making thegesture will thinkit means money.
3. A theme park is a collection of rides, exhibitions or other attractions that are based on a commontheme.4. The park has a conservation center that helps protect marine animals and their habitats in the
riversandcoastal waters ofAsia.
5. Visitors can go on exciting rides where they can feel what it is like to do thethings they have seen
theirheroes doin themovie.
6. OprahWinfrey is ablack woman whose rise tofame is an inspiring story.
(二)定語從句分爲限定性定語從句和非限定性定語從句：
限定性定語從句：從句對先行詞進行必要的描述或說明，缺少它，則句義顯得不完整，從句與先行詞
緊密相連。
非限定性定語從句：對先行詞進行補充說明，解釋，它與先行詞之間有逗號隔開。
1. Beforeshecould move, sheheard aloud noise,which grewtoa terrible roar.
2. Treeafter tree went down, cutdown bythe water, which must havebeen three meters deep.
3. Flora,whose beautifulhair anddress were all cold andwet, startedcrying.
4. Their talk includes rhythm and rhyming words as well as tongue twisters, which often make the
audience applaud.
(三)關係詞前面可以根據定語從句的內容加上一些介詞，這些關係詞在介詞後面常用 which 或 whom.
1. There was a man with whom I would have to work together and finally the manager of thecompany.2. Many people who saw the film were afraid to swim in the sea when they remembered the scenes
in which people were eaten bythe shark.
知識重點與難點
(一)當先行詞有最高級，序數詞修飾，是不定代詞，或是 all,no, only等形式時，關係代詞一般用that，
而不能用 which。
1. The Titanic was the largest shipthat hadeverbeen built atthattime.
2. Thereis onething that keeps worrying me.
(二)當先行詞是表示時間，地點，原因的詞時，關係詞用 when, where, why 還有which, that
1. I'mveryglad toreturn tomy hometown where I hadlived for10 years.
2. This is my hometown which Iused totalk about toyou.
3. Ithink Ican understand thereason why hedidn't tellthe truth tome.
4. No one believes thereason that he gaveus abouthis absence at themeeting.
(三)定語從句的簡化表達：
1. The man who is sitting onthe platformis a professorfromWuhanUniversity.
2. The letter thatwas mailed lastnight will reach himtomorrow.
3. The questionthat is beingdiscussed is veryimportant.
4. Youarewelcome toa partytobe givenin ourclass at7:45.
說明：以上的定語從句部分可以用更加簡單的非謂語形式表達出來：
1. The man sittingon theplatformis a professorfromWuhan University.
2. The letter mailed lastnight will reach himtomorrow.
3. The questionbeing discussedis veryimportant.
4. Youarewelcome toa partytobe givenin ourclass at7:45.
說明：修飾一個名詞除了後面用定語從句以外，還可以用非謂語動詞形式：doing短語，done短語，
beingdone短語，tobe done短語修飾。其結構和意思如下：
1. 被修飾名詞+doing短語： 正在做....的人/正在發生的事。
2. 被修飾名詞+ done短語： 被.....的人/事
3. 被修飾名詞+beingdone短語：正在被.....的人/事
4. 被修飾名詞+ tobe done短語：將要被.....的人/事
(1)Do youknow theman talkingto my sister?
(2)The "crazy"gesture, moving the indexfinger in acircle in front of the ear,means "youhave a
phone call"in Brazil.
(3)Did yousee that carbeingrepaired ?
(4)In a camera,the lensmust befocused onthe objectto bephotographed.
(5)The students toattend themeeting will arrive heretomorrow.
(6)Goods importedfromabroad arenotalways betterthan thosemade inChina.
(7)The Yellow River,said tobe "themotherriver"runs across China like a huge dragon.
總結：以上做定語的那些短語就是英語語法中所說的分詞，不定式的各種形式作定語。
1. 這些短語作定語應放在被修飾名詞的後面。如果單獨一個V-ing或 V-ed形式作定語，則可以放在被
修飾名詞前面。
2. 分詞作定語時，其動作應與全句動作同時發生。V-ing表示主動意義和正在做，V-ed表示被動意義。
beingdone表示正在被做的
3. 不定式作定語表示將要發生的，tobe done表示將要被做的
