1. 三大從句用法一大堆,要背嗎
為您解答
看你是哪個年級的了。。
你要是初中的話,建議不要背那麼多語回法,一個是初中老師有答時講不清楚,一個是初中的話英語靠語感就可以
要是高中,那建議你背一下,再配一些題,像一本之類的語法書,高中學語法還是很管用的,分析句子成分啊,翻譯啊,作文之類的語法都蠻重要
大學就更不用說了,語法必學的
希望能幫到您
2. 求初中英語各類從句的用法
英語的復合句包括並列句和主從句兩種。其中並列句是兩句地位完全相同的簡單句用表示並列關系的連詞連接而成(例如and,or等)。主從句雖然有兩套主謂結構,但是其中一套是主要的,稱為主句,另一套只是充當主句的某個成分,稱為從句。英語從句分為賓語從句,定語從句,狀語從句,主語從句,表語從句,同位語從句6種。
賓語從句和表語從句
賓語從句和表語從句是從句中較為簡單的一種。這兩種從句是以句子的形式代替了主句中的賓語或表語,也就是直接占據了謂語後賓語或表語的位置,比較明顯。引導賓語從句或表語從句的引導詞最常用的是that,以及關系代詞what,which,who(whom),關系副詞when,where,how,whether。
由於主從復合句中有兩套主謂結構,因而要注意時態的搭配。時態搭配的原則是從句服從主句,但是可以根據情況靈活配置,不過主從句之間不出現時段斷層。因而一般常見的配置組合為:
主句 現在時 過去時 將來時
從句 現在時,過去時,將來時 過去的時態 一般現在時
註:當從句的內容是客觀真理時,無論主句是什麼時態,從句永遠用一般現在時,例:The teacher told the students that the light travels faster than the sound in the air.
定語從句
定語從句是從句充當定語的用法,引導詞與時態搭配的規則與賓語從句相同。定語從句與賓語從句區分的要點是賓語從句充當主句的賓語,占據了主句中賓語的位置,而定語從句的主句結構完整,定語從句在引導詞的引導下跟在被修飾的主句的主語或賓語(表語)之後,起修飾作用,而被修飾的詞語稱為先行詞。例如:
①People don』t know who runs in the morning in the park everyday.人們不知道是誰每天早晨在公園里跑步。
②People don』t know the man who runs in the morning in the park everyday.人們不知道那個每天早晨在公園里跑步的人是誰。
在②中,主句部分People don』t know the man句子結構是完整的,the man是被從句修飾的成分,即先行詞。
注意,that是引導短語從句的引導詞中最靈活而且用法最多的,通常可以代替所有關系代詞(which,what,who,whom),而且有幾種情況必須使用that:A.先行詞是不定代詞時;B.先行詞受形容詞最高級修飾時;C.當先行詞被any, few, little, no, all, much, some等詞修飾時D.當先行詞為序數詞或被序數詞所修飾時;E.當先行詞被the very, the only, the last, the just, the same等修飾時;F.當先行詞既包含人又包含物時當先行詞是疑問代詞who,which,what或主句以這些詞開頭時;G.當先行詞為主句表語或關系代詞為從句表語時。
以下兩種情況一般只使用which:在「介詞+關系代詞」結構中先行詞為「those+表事物的復數名詞」時。
當先行詞為時間,地點或方式名詞時,就有是使用關系代詞和關系副詞的問題了。原則非常簡單:如果從句主謂賓結構完整,就使用關系副詞;如果從句主謂賓結構不完整,使用關系代詞。例如:
①This is the place where they met each other for the first time.
這是他們第一次見面的地方。
②This is the place that they will never forgrt.
這是他們永遠不會忘記的地方。
在①中,從句部分的主謂賓結構是完整的,因而主句中的「place」充當了從句的地點狀語,所以使用了關系副詞where;在②中從句中沒有賓語,因而主句中的「place」 充當了從句的賓語,所以使用了關系代詞that。
注意定語從句中有一類非限制性定語從句。非限制性定語從句是先行詞的附加說明,去掉了也不會影響主句的意思,它與主句之間通常用逗號分開,例如:
This is the house which we bought last month. 這是我們上個月買的那幢房子。(限制性)
The house, which we bought last month, is very nice.這幢房子很漂亮,是我們上個月買的。(非限制性)
2) 當先行詞是專有名詞或物主代詞和指示代詞所修飾時,其後的定語從句通常是非限制性的,例如:
My house, which I bought last year, has got a lovely garden. 我去年買的的那幢房子帶著個漂亮的花園。
3) 非限制性定語從句還能將整個主句作為先行詞, 對其進行修飾, 這時從句謂語動詞要用第三人稱單數,例如:
He seems not to have grasped what I meant, which greatly upsets me. 他似乎沒抓住我的意思,這使我心煩。
Liquid water changes to vapor, which is called evaporation. 液態水變為蒸汽,這就叫做蒸發。
說明:關系代詞that和關系副詞why不能引導非限制性定語從句。
狀語從句
狀語從句的種類最多,知識點比較零散,歸納之後有以下幾種:
時間狀語從句
引導詞:when, as, while, as soon as, while, before, after, since, till, until, the minute, the moment, the second, every time, the day, the instant, immediately , directly, no sooner … than,hardly …when, scarcely … when
例:
I didn't realize how special my father was until I was 18.
While Tom was watching TV, his wife was reading.
No sooner had I arrived home than it began to rain.
Every time I take your advice, I get into trouble.
地點狀語從句
引導詞:where, wherever, anywhere, everywhere
Generally, air will be heavily polluted where there are factories.
Wherever you go, you should bring the mp3 player with you.
原因狀語從句
引導詞:because, since, as, since, seeing that, now that, in that, considering that, given that, considering that, in as much as, in so much as
Now that everybody has come, let's begin our clas.
Considering that he is no more than 10 years old, his height of 1.60 m is not normal.
目的狀語從句
引導詞:so that, in order that, lest, in case, for fear that, in the hope that, for the purpose that, to the end that
The boss asked his secretary to give him the letter so that he could send it out himself.
The instructor raised his voice that the students at the back could hear more clearly.
結果狀語從句
引導詞:so … that, so… that, such … that, such that, to the degree that, to the extent that, to such a degree that,

條件狀語從句
引導詞:if, unless, as/so long as, only if, providing/provided that, suppose that, in case that, on condition that
You will certainly succeed so long as you keep on trying.
Provided that there is no opposition, we shall call off the meeting.
讓步狀語從句
引導詞:though, although, even if, even though, as(用在讓步狀語從句中 必須要倒裝),while ( 一般用在句首 ),no matter …, in spite of ,the fact that, while, whatever, whoever, wherever,whenever, however, whichever
Much as I respect him, I can't agree to his proposal.
No matter how hard he tried, she could not change her mind.
比較狀語從句
引導詞:as(同級比較), than(不同程度的比較), 特殊引導詞:the more … the more … ; just as …, so…; A is to B what /as X is to Y; no … more than; not A so much as B

方式狀語從句
引導詞:as, as if, how, the way
When in Rome, do as the Roman do.
She behaved as if she were the boss.
Sometimes we teach our children the way our parents have taught us.
應當注意的知識點有:
引導時間狀語從句的連詞
主要有when, while, as, by the time, before, after, since, till/until, as soon as等。其中when、while和as都可表示"當……時候",但用法有區別:
1) when意為"在……時;當……時",可表示"點時間"或"段時間",從句謂語可以 是終止性動詞,也可以是延續性動詞。例如: When I got home, he was having supper.
2) as意為"邊……邊……"或"與……同時",重在表示兩個動作同時發生、伴隨進行。as從句是終止性動詞時,主句通常也必須是終止性動詞。例如: They sang as they danced.
3) while只可表示"段時間",從句謂語只限於延續性動詞。例如: While I was sleeping, my father came in.
引導原因狀語從句的連詞
原因狀語從句一般由because, since, as, for引導. 注意as, because, since 和for的區別:
1) 如果原因是構成句子的最主要部分, 一般用because。because引導的從句一般不放在句子的開頭。例如: I missed the train because I got up late.
注:對於以why開頭的問句, 一般只能用because引導的從句來回答。
2) 如果原因已為人們所知, 或不如句子的其餘部分重要, 就用as或since、since 比as稍微正式一些。as和since引導的從句一般放在句子的開頭。例如:
As he was not well,I decided to go there without him.
Since this method doesn't work, let's try another.
3) for表示所說的理由是一種補充說明,因此,for引導的從句可以放在括弧里,而
且for引導的從句一般不放在句子的開頭。例如: I decided to stop and have lunch, for I was feeling quite hungry.
引導結果狀語從句的連詞
主要有so/such…that…,so that等。
1) so...that結構在某種情況下可以與enough to和too...to結構相互轉換。例如:
She is so short that she can't reach the buttons of the lift.
=She is too short to reach the buttons of the lift.
2)so that也可以引導結果狀語從句,意為"結果是;以致於"。例如: They missed the bus so that they were late for class.
注:so that也可引導目的狀語從句, 此時可用to或in order to替換, 將其改為簡單句。
例如: He got up early so that he could get to school on time.
=He got up early to get to school on time.
=In order to get to school on time,he got up early .
主語從句
主語從句主要有三類:
由連詞that引導的主語從句。 例如:That you will win the medal seems unlikely.
你想獲得獎牌看起來是不可能的。
用連接代詞which或連接副詞if, whether 引導的主語從句。 例如:
Which of them escaped from the prison is still a mystery.
他們哪一個是從監獄里逃跑的,仍然是個謎。
When they will come hasn』t been made pubic.
他們什麼時候來還不知道。
Whether she is coming or not doesn』t matter too much.
她來不來都無關緊要。
用關系代詞(what,whatever,who,whoerver)引導的主語從句。
主語從句可以直接放在主語位置上,也可以用it作形式主語, 而將從句放在句末(尤其是當謂語較短時)。
當what引導的主語從句表示「…的東西」時,一般不用it作形式主語。
錯:It is a book what he wants.
對:What he wants is a book. 他想要的是本書。
如果帶主語從句的句子是疑問式,則必須用it作形式主語的結構。
例如:Has it been settled who will be sent to carry out the task ?
誰將被派去執行這項任務決定了嗎 ?
固定用法:It is +名詞+從句;It is +形容詞+從句;It is +過去分詞+從句;It +不及物動詞+從句(當「及物動詞 + 賓語」較短時,也可用這種結構);It +某些固定結構+ 主語從句。
同位語從句
在復合句中用作同位語的從句叫同位語從句。它一般跟在某些名詞後面,用以說明該名詞表示的具體內容。如: I heard the news that our team had won.我聽到了我們隊獲勝的消息。
可以跟同位語從句的名詞通常有news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,words(消息),possibility等。
英語中引導同位語從句的詞有連詞 that,whether,連接副詞 how,when,where等。(註:if,which 不能引導同位語從句。)如:I have no idea when he will be back.我不知道他什麼時候回來。
有時同位語從句可以不緊跟在說明的名詞後面,而被別的詞隔開。如:The thought came to him that maybe the enemy had fled the city. 他突然想起可能敵人已經逃出城了。
這是我教學中總結的,學生們反映還不錯,有什麼不明白的再問我。
3. 初中英語面試,哪些語法是常考點,會涉及到三大從句嗎
詞類常考名詞,動詞,代詞,形容詞,副詞 介詞。時態會考一般現在時現在進行時,一般過去時,現在完成時,一般將來時,現在進行時,過去進行時 以及被動語態。從句會考定語從句,賓語從句和狀語從句。

2. 主語從句很多情況下都可以放到句子後面,而用代詞it作形式上的主語. :
3. 形式賓語
4. 由名詞性關系代詞whatever, whoever, whichever 等引起的賓語從句
5. whether and if 都能引導從句, 但用法有所不同. 當主語從句直接位於句首時,應用whether,而不用if. Whether 後能直接or not, 但if 不能.
Whether he will come or not is not known.
6. 在名詞reason後的表語從句必須用that引導, 不可誤用 because.
The reason why he is often late for class is that he has the bad habit of getting up late in the morning.
二: 定語從句
1. 引導定語從句的關系詞有who, whom, whose, that, when, where, why and which. 在非限制定語從句中, 只可用which, who, whose, where , when., 如果指代前面整個句子, 多用which.
2. 當引導定語從句的先行詞前有all, any, no, little, much, very first 等詞, 或先行詞前為形容詞最高級所修飾時,或先行詞為all, anything, nothing, something, everything 時,從句的引導詞只能用that.
3. as 可做引導詞引導定語從句, 多和such, the same 連用. As 引導的定語從句也可修飾整個句子, 既可放在先行詞後,也可放在句子開頭.
4. 介詞+which/whom/whose從句
5. 代/名+介詞+which 從句
6. 同位語從句和定語從句
三 狀語從句:
修飾主句中的動詞, 形容詞和副詞, 通常有從屬連詞引導, 按其意義和作用可分為時間, 地點, 條件, 原因, 讓步, 目的, 結果, 方式, 比較.等
1. 時間狀語從句:
1) 常見連詞有 after, as, before, once, since, till, (not)until, when, whenever(no matter when), while, as long as, as soon as etc.
2) no sooner…than, hardly(scarcely, barely)…when: 剛做…就….

5. 讓步狀語從句:
1): even if, though, even though, while(盡管) no matter what/how/which, however, whatever, whichever, however etc.
2) 由as 引起的讓步從句, 語氣較強烈,被強調的詞須放在句首.

2) 比較級+than, so much/a lot more than
3) no more…than, not more…than, less…than
4) the more…the more
6. 初中英語從句都有哪些啊,有沒有詳細的歸納
1.主語從句
1)主語從句可直接位於主語的位置,如果從句較長,謂語又較短,可用it作形式主語,而將從句放在句末。常見的句型有:
*It is a fact\a pity\a question\good news that...
2.賓語從句
1)賓語從句可位於及物動詞、介詞和某些形容詞後。連詞that常可省略。介詞後一般接疑問詞引導的賓語從句。in that(因為),except that(除了),but that(只是)已構成固定搭配,其他介詞後一般不接that引導的賓語從句。
*I promised that I would change the situation.
3.表語從句
表語從句出現在結構為「主語+系動詞+表語從句」的句子中。表語從句除可用that,what,when,why,whether,how等引導外,還可由because,as if(though)等引導。that常可省略。如主句主語為reason,只能用that引導表語從句,不可用because.
The reason why so many people died there is that there were not enough food supplies.
4.同位語從句
同位語從句用於對前面出現的名詞作進一步說明,一般用連詞that引導,由於先行名詞的意義不同,也可用whether,who,when,where,what,why,how等引導。常見的先行名詞有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有時由於謂語較短,將同位語從句位於謂語之後。
I had no idea how many books I could borrow at a time.
5.定語從句
定語從句所修飾的先行詞可以是名詞或代詞,也可以是一個句子。定語從句通常位於先行詞之後,由關系代詞或關系副詞引導。
The girl whose parents died in an accident is living with her grandmother.
7. 初中英語有哪幾種從句具體的用法老師講的太差了聽不懂…
從句是相對於主句而言的,即它是從屬於某一個主句,而不能單獨作一個句子。在英語中主要有三大從句,即:
1. 名詞性從句(包括主語從句,賓語從句,表語從句,同位語從句)
2. 定語從句
3. 狀語從句(包括時間、條件、結果、目的、原因、讓步、地點、方式等)。
1)主語從句用作主語,如:
That the earth is round is true. 地球是圓的是真實的。
2)賓語從句用作賓語。如:
Do you know where he lives?
3)表語從句用作表語,如:
My opinion is that you should not go alone. 我的意見是你不應單獨前往。
4)同位語從句用於解釋說明前面的名詞。如:
The fact that the earth is round is true. 地球是圓的的事實是真實的。(that從句用於解釋說明the fact)
5)定語從句相當於一個形容詞,用於修飾前面的名詞。如:
The student who answered the question was John. 回答問題的學生是John.
6)狀語從句相當於一個副詞,如:
When it rains, I usually go to school by bus. 天下雨時,我通常坐公共汽車上學。(時間狀語)
If he comes tomorrow, you will see him. 如果他明天來,你就可以看見他。(if 引導的條件狀語從句,其結構為:if +狀語從句,+主句)。要注意在狀語從句中有一個規則是「主將從現」,即主句是將來時,則從句要用一般現在時表示將來。
He returned home to learn his daughter had just been engaged.他回家後得知女兒剛剛訂婚了。(結果狀語,結果狀語只是僅限於learn(得知),find(發現),see,hear,to be told(被告知),make(使得)等具有界限含義的動詞。)
You must speak louder so that /in order that you can be heard by all. 你必須大聲說話,才能讓所有人聽到你說話。(目的狀語,可以由that, so that, in order that, lest, for fear that, in case等詞引導。)
Since /As the weather is so bad, we have to delay our journey. 天氣那麼糟,旅行推遲了。 (原因狀語從句,常用 because, since, as, for fear (恐怕), seeing that (既然) ,now that (=since), considering that (考慮到) 等引導。)
Though/Though he was worn out, (still) he kept on working. 雖然他已經精疲力竭了,但仍然繼續工作。(讓步狀語從句,引導的連詞主要有以下這些:though, although, as; even if, even though; whether...or...; no matter+疑問詞,疑問詞-ever.)
Where I live there are plenty of trees. 我住的地方樹很多。(地點狀語從句,通常由where, wherever 引導。)
As water is to fish, so air is to man. 我們離不開空氣,猶如魚兒離不開水。(方式狀語從句通常由as, (just) as…so…, as if, as though引導。)
主句和從句的劃分方法是相同的。句子的成分從謂語動詞處來劃分比較容易。謂語動詞前面的部分是主語,後面常接賓語,修飾謂語動詞的是狀語,修飾主語、賓語的是定語,若謂語是系動詞,則系動詞後的部分是表語。如:
I am a teacher. 其中,I 是主語,am是謂語,a teacher 是表語。
He likes playing football very much. 其中,he是主語,likes是謂語,playing football是賓語,very much是狀語。
8. 英語初中的從句有哪幾種 用法是什麼
