Ⅰ 英語語法有哪些
首先我們來了解英語學習的本質。我們學習英語,為的是日後工作學習專無障礙溝通交流屬。英語不比數學和語文,它不是一門學問,不需要深入研究,只要多多練習,多說多用就能學會了。Ⅱ 常見英語語法介紹
時態講解
一、一般現在時主要用於:
1 、表示經常性或習慣性動作。 e.g. It seldom snows here.
2 、表示現在的特徵或狀態。 e.g. He is always ready to help others.
3 、普遍真理。 e.g. Action speaks louder than words.
4 、劇情圖片介紹,背景說明,動作解說。 e.g. (Tom enters the room and sits at the table)
Doctor : What's your trouble, young man?
Tom : I've caught a cold, doctor.
5 、時間、條件、讓步、方式狀語從句表將要發生的動作時。
e.g. Tomorrow we shall go for an outing unless it rains.
與這種時態連用的時間狀語常有: always, often, never, seldom, usually, once, a week, now 等。
二、一般過去時主要用於:
1 、表示過去某個時間發生的動作或情況(包括習慣性的動作或狀態)
e.g. When did you read the novel? She often came to help us in those days.
2 、談到過去的情況時 e.g. I didn't know you were so busy.
3 、談到已死人的情況時 e.g. Lei Feng was a great communist fighter.
與這個時態連用的時間狀語常有:
yesterday, last night, the other day, two months ago, in 1985, then, just now, when, after, as soon as 引導的時間狀語從句,表示主句動作開始的時間。
三、現在完成時主要用於:
1 、表示到現在為止這一時期中發生的動作或情況,即多次動作的總和。
e.g. We have learnt four English songs this month. How many times have you read the novel?
For many days we haven't seen each other.
2 、表示對現在有影響的某一已發生的動作。
e.g. The delegation has left 代表團已經走了(說明現在不在這里) Look, what you have done. 看你乾的事。
與這一時態連用的時間狀語有: already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短語,連詞 since 引導的時間狀語從句。
一般過去時與現在完成時的區別:
一般過去時:重在說明動作在過去發生時的具體情況(時間、地點、方式、對象、細節等)。
現在完成時:只提起已發生的動作(事實)及其影響,不說明動作發生時的具體情況。
cf. Have you had your lunch? What did you have for lunch?
I have ever been to the Great Wall, and I went there last summer with my father.
註:現在完成時表達的動作常具有反復性,故下面一句是錯的:
Have you seen the six thirty's news program? 應改為: Did you see the six thirty's news program?
四、現在完成進行時主要用於:表示過去開始的某一動作一直持續到現在,以至延伸到將來,它強調動作延續時間之長久。e.g. I've been writing an article. 我一直在寫一篇文章。(還在寫)
cf. I've written an article. 我寫了一篇文章。(已寫完)
It has been raining these days. 這些天一直在下雨。
五、過去完成時
1 、過去完成時是一個相對時態,表示過去的過去,只有在兩個過去發生的動作相比較時才可顯示出來。
e.g. As soon as we got to the station, the train had left.
註:主從句表達的動作緊接時,即兩動作發生的時間沒有明顯時間上的懸殊或空檔時,主從句都可用一般過去時。 e.g. Where did your brother study before he joined the army?
2 、過去完成時可表示截止過去某一時間動作的總或動作的結束。
e.g. By the end of last month. We had reviewed four books By eight o'clock, he had finished his homework.
與這個時態連用的時間狀語常有: by 1985, by eight o'clock, by then, by the end of last month, by the time when, when, as soon as, before 等連詞引導的時間狀語從句,表示主句動作結束的時間。
(六)現在進行時主要用於:
1 、表示現在或現階段正在進行的動作。 e.g. Listen, someone is crying. What are you doing these days?
2 、代替一般現在時,表示經常性動作或狀態,而含有某種感情色彩。
e.g. How are you feeling today? 你今天感覺怎樣?(顯得親切)
He is doing well in his lessons. 他的功課很好。(贊揚)
You are always boasting. 你老愛吹牛。(厭煩)
3 、動詞 go, come, leave, arrive 等表將要發生的動作時。 e.g. They are leaving for Shanghai.
與這種時態連用的時間狀語常有: now, these days, recently, this week 等。
七、過去進行時主要用於: 表示過去某個時刻或階段正在進行的動作。
e.g. At that time she was working in a PLA unit. 那時她在解放軍某部工作。
What were you doing this time yesterday?
與這個時態連用的時間狀語常用: at nine o'clock, this time last night, these days, at that time 等。
用 when 引導的時間狀語從句表示主句的動作正在進行的時間。
e.g. When he came in, I was reading a newspaper.
註:
1 、 while 引導時間狀語從句敘述過去的動作時,從句常用過去進行時。
e.g. I read a magazine while I was waiting for the bus.
2 、 when 用作並列連詞,意為「這時」,連接兩分句時,第一句多用過去進行時。
e.g. I was reading a newspaper when he came in.
一般過去時與過去進行時的區別:
一般過去時:強調過去某一時間開始或完成的動作。
過去進行時:強調過去某一時間正在進行的動作。
試區別下面兩句:
We were building a reservoir last winter. 去年冬天我們在修建一座水庫。(可能尚未建成)
We built a reservoir last winter. 去年冬天我們修建了一座水庫。(已經建成)
八、一般將來時主要用於: 表示將要發生的動作或情況
e.g. Tom will have a bike of his own.
與這個時態連用的時間狀語常用: tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
一般將來時態與其它結構表將來情況的區別:
一般將來時態 :主要從時間的角度表將要發生的動作或情況。
be going to 結構 :①表(主觀上)打算或准備做某事時。 ②表有發生某事的預兆時。
e.g. They are going to have a competition with us in studies. It is going to rain.
據以上區別,故下面一句是錯的:
I am going to be eighteen years old next year. 應改為: I shall be eighteen years old next year.
be about to do sth 結構 :意為「剛要做某事」、「馬上要做某事」強調時間之緊迫性。
e.g. We are about to discuss this problem. 我們將馬上討論這個問題。
be to do sth 結構: 表示按計劃、安排、規定將實施某事或表示註定會發生某事。
e.g. When is the train to leave. All these things are to be answered for.
及物動詞與不及物動詞
英語中按動詞後可否直接跟賓語,可把動詞分成及物動詞與和及物動詞。
1.及物動詞: 字典里詞後標有vt. 的就是及物動詞。及物動詞後必須跟有動作的對象(即賓語),可直接跟賓語。see 看見 (vt.) +賓語 I can see a boy.
2.不及物動詞:字典里詞後標有vi. 的就是不及物動詞。不及物動詞後不能直接跟有動作的對象(即賓語)。若要跟賓語,必須先在其後添加上某個介詞,如to,of ,at後方可跟上賓語。
具體每個動詞後究竟加什麼介詞就得背動詞短語了,如listen to,look at…..
3. 賓語(動作的對象):是名詞或代詞,或相當於名詞的詞或短語(如動名詞)。其它詞不看作動作的對象呢。
4.舉例:「看」
(1)see 看見 (vt.) +賓語 I can see a boy.
(2)look 看 (vi.) x賓語(即不能直接加賓語). Look! She is singing.
Look carefully! (注意:carefully 是副詞,不是名詞,故不作賓語喲)
(3)look at 看…….+賓語 Look at me carefully! (me是代詞,作賓語了)
連系動詞
連系動詞本身有一定的詞義,但不能獨立作謂語,必須與表語一起構成謂語。
表語通常由名詞、形容詞,或相當於名詞或形容詞的詞或短語等充當,說明主語是什麼或怎麼樣。
一、 連系動詞的類型有:
1. "存在"類:表示存在或具有某種特徵或狀態.這類連系動詞強調"存在"。常見的有:be(是),look(看起來),feel(摸上去),seem(似乎是),appear(似乎、顯得),prove(證明是),smell(聞起來),taste(嘗起來),sound(聽起來)等。例如:
The story sounds true.
Those oranges taste good.
2. "持續"類:表示某種情況或狀態的持續。這類連系動詞強調"持續"。常見的有:remain(依然),keep(保持),stay(保持),continue(繼續、仍舊),stand(處於某狀況或情形)等。例如:
Why don't you put the meat in the fridge? It will stay fresh for several days.
It's already ten in the morning. The store remains closed. What's the matter?
3. "變化"類:表示由一種情況或狀態變化成另一種情況或狀態。這類連系動詞強調"變化"後的情況或狀態.常見的有:become(變成), turn(變成), grow(變得), go(變得)等。例如:
Put the fish in the fridge, or it will go bad in hot weather.
二、注意事項
1. 有些連系動詞通常不用於被動語態和進行時態中。如:feel, taste等詞。例如:
-Do you like the material?
-Yes, it feels very soft.
2. 一般情況下,連系動詞主要跟形容詞或分詞作表語。例如:
Be careful when you cross this very busy street. If not, you may get run over by a car.
3. 能跟名詞作表語的連系動詞常見的有:be, become, appear, seem, prove, remain和turn等.注意:turn後跟(表示主語身份的)名詞作表語時,不加冠詞。例如:
Twenty years later, he turned teacher.
The population growth in China remains a problem.
4. 連系動詞也可跟不定式(to do / to be),常見的有:appear, seem, remain, prove, look等。例如:
Having a trip abroad is certainly good for the old couple, but it remains to be seen whether they will enjoy it.
On the long journey, Peter proved to be a most interesting guide. We all had a wonderful time.
終止性動詞與延續性動詞
終止性動詞指不會持續一段時間的動作,即動作在瞬間或短時間內完成。 例如:get arrive 這類動詞不與一段時間連用
終止性動詞:表示不能延續的動作,即動作發生後立即結束。如:begin,arrive, borrow, ...終止性動詞的肯定式是不能持續的,所以不能和表示一段時間的狀語連用,而終止性的否定式就可以和表一段時間的狀語.
一、延續性動詞和終止性動詞的概念
英語中,動詞按其動作發生的方式、動作發生過程的長短,可分為延續性動詞和終止性動詞。
延續性動詞表示能夠延續的動作,這種動作可以延續下去或產生持久影響。如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。
終止性動詞也稱非延續性動詞、瞬間動詞或短暫性動詞,表示不能延續的動作,這種動作發生後立即結束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。
二、延續性動詞的用法特徵
1.延續性動詞可以用於現在完成時,其完成時態可與表示"段時間"的狀語連用。表示"段時間"的短語有:for two years, ring the past three years, since last year, how long等。如:I have learned English since I came here.自從我來到這兒就學英語了。
2.延續性動詞不能與表示短暫時間的"點時間"狀語連用。如:It raind at eight yesterday morning.(誤) rain為延續性動詞,而at eight表示"點時間",前後顯然矛盾。如果用延續性動詞表示一瞬間的動作,可以藉助come, begin, get等終止性動詞來表示。上句可改為:It began to rain at eight yesterday morning.(正)又如:
-When did you get to know Jack?
-Two years ago.
-Then you've known each other for more than two years.
-That's right.
三、終止性動詞的用法特徵
1.終止性動詞可用來表示某一動作完成,因此可用於現在完成時。如:
The train has arrived.火車到了。
Have you joined the computer group?你加入電腦小組了嗎?
2.終止性動詞表示的動作極其短暫,不能持續。因此,不可與表示一段時間的狀語連用(只限肯定式)。如:
(1)他死了三年了。
誤:He has died for three years.
正:He has been dead for three years.
正:He died three years ago.
正:It is three years since he died.
正:Three years has passed since he died.
(2)他來這兒五天了。
誤:He has come here for five days.
正:He has been here for five days.
正:He came here five days ago.
正:It is five days since he came here.
正:Five days has passed since he came here.
(1)、(2)句中的die、come為終止性動詞,不能與表示"段時間"的狀語連用。那麼,應如何正確表達呢?可以採用下面的四種方法:
(1)將句中終止性動詞轉換為相應的延續性動詞,如上面兩例中的第一種正確表達方式。下面列舉幾例:leave→be away, borrow→keep, buy→have, begin/start→be on, die→be dead, move to→live in, finish→be over, join→be in/be a member of, open sth.→keep sth. open, fall ill→be ill, get up→be up, catch a cold→have a cold。
(2)將句中表示"段時間"的狀語改為表示過去確定時間的狀語,如下面兩例中的第二種正確表達方式。
(3)用句型"It is+段時間+since..."表達原意,如上面兩例中的第三種正確表達方式。
(4)用句型"時間+has passed+since..."表達原意,如上面兩例中的第四種正確表達方式。
3.終止性動詞可用於現在完成時否定式中,成為可以延續的狀態,因而可與表示一段時間的狀語連用。如:
He hasn't left here since 1986.
I haven't heard from my father for two weeks.
4.終止性動詞的否定式與until/till連用,構成"not+終止性動詞+until/till ..."的句型,意為"直到……才……"。如:
You can't leave here until I arrive.直到我到了,你才能離開這里。
I will not go to bed until I finish drawing the picture tonight.今天晚上直到我畫完畫,我才上床睡覺。
5.終止性動詞可以用於when引導的時間狀語從句中,但不可以用於while引導的時間狀語從句中。when表示的時間是"點時間"(從句謂語動詞用終止性動詞),也可以是"段時間"(從句謂語動詞用延續性動詞)。而while表示的是一個較長的時間或過程,從句謂語動詞用延續性動詞。如:
When we reached London, it was twelve o'clock. (reach為終止性動詞)
Please look after my daughter while/when we are away. (be away為延續性動詞短語)
6.終止性動詞完成時不可與how long連用(只限於肯定式)。如:
誤:How long have you come here?
正:How long have you been here?
正:When did you come here?

Ⅳ 英語語法的介紹
英語語法是針對英語語言的語法進行的研究。語法是組詞造句的規則,是版把合適的詞放進合適位權置的藝術文化底蘊,語法可以分成為兩大部分:分別為詞法和句法。詞法包括各類詞的形態及其變化,句法主要講句子的種類和類型,句子成分以及遣詞造句的規律。語法的精髓在於掌握語言的使用。
Ⅳ 英語中的一些常用語法
語從句(Subject Clause)
定義:如果一個句子在復合句中充當一個主語,那麼這個句子就是主語從句.
第一部分:常規主語從句,即句子在復合句中充當一個主語
第二部分:為了防止句子頭重腳輕,通常把形式主語it放在主語位置,真正主語擱置於句末
狀語從句 (Adverbial Clause)
狀語從句指句子用作狀語時,起副詞作用的句子。它可以修飾謂語、非謂語動詞、定語、狀語或整個句子。根據其作用可分為時間、地點、原因、條件、目的、結果、讓步、方式和比較等從句。狀語從句一般由連詞(從屬連詞)引導,也可以由片語引起。從句位於句首或句中時通常用逗號與主句隔開,位於句尾時可以不用逗號隔開。
同位語部分是個句子,就是同位語從句,這種用法比較"固定",把關鍵的幾個詞背下來.
下面這個材料供參考.
===========================
一、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。
I had no idea that you were here.我不知道你在這里。
二、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。如:
I』ve come from Mr wang with a message that he won』t be able to see you this afternoon. 我從王先生那裡來,他讓我告訴你他今天下午不能來看你了。
三、英語中引導同位語從句的詞通有連詞 that,whether,連接副詞 how,when,where等。(註:if,which 不能引導同位語從句。)如:
l have no idea When he will be back.我不知道他什麼時候回來。
He must answer the question whether he agrees to it or not.
他必須回答他是否同意這樣一個問題。
四、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:
Several years later,word came that Napoleon himself was coming to inspect them.
幾年以後,有消息傳來說拿破崙要親自視 察他們。
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。
五、同位語從句與定語從句的區別。
1、同位語從句與前面的名詞是同位關系,即說明它前面名詞的內容;而定語從句與前面的名詞是修飾與被修飾關系,即限定它前面的名詞范圍,或補充一些情況。如:
The news that l have passed the exam is true.我通過了考試這一消息是真的。
(同位語從句,即從句所表達的意思就是前面名詞的內容。)
The news that he told me just now is true.他剛才告訴我的消息是真的。
(定語從句,從句對前面名詞起修飾限製作用,即「他告訴我的」那個消息,而不是別的消息。)
2、引導同位語從句的that是連詞,在從句中不充當任何成份,而引導定語從句的that是關系代詞,除起連接作用外,還在從句中充當主語、賓語或表語等。如:
The idea that computers can recognize human voices surprises many people.
計算機能夠識別人的聲音的想法使許多人感到驚奇。(that在從句中不充當任何成份。)
The idea that he gave surprises many people.他提出的觀點令許多人感到吃驚。
(that在從句中作gave的賓語。)
一個名詞(或其它形式)對另一個名詞或代詞進行修飾,限定或說明,這個名詞(或其它形
式)就是同位語。同位語與被它限定的詞的格要一致,並常常緊挨在一起。
Ⅵ 英文語法詳解
there was an exceptionally interesting person (with whom)I dated 是定語從句,修飾 person,省略連接詞with whom。有一個我交往過的非常有趣專的人。 I thought I had found someone special to share my life with 是賓語從句,to後面表目的,我想我屬找到了一個特別的人來分享我的生活。 What is most important to sb 對某人來說最重要的是...... 。
Ⅶ 介紹一些簡單的英語語法知識.
一、英語語句基本結構分析:
主謂賓結構:
主語:可以作主語的成分有名詞(如boy),主格代詞(如you),動詞不定式,動名詞等。主語一般在句首。注意名詞單數形式常和冠詞不分家!
謂語:謂語由動詞構成,是英語時態、語態變化的主角,一般在主語之後。不及物動詞(vi.)沒有賓語,形成主謂結構,如:We come.
賓語:賓語位於及物動詞之後,一般同主語構成一樣,不同的是構成賓語的代詞必須是『代詞賓格』,如:me,him,them等
例:The boy needs a pen.主語the boy,謂語needs(need的第三人稱單數形式),賓語a pen.
主系表結構:
主語:同『主謂賓』結構。
聯系動詞(Link verb):be動詞(am,is,are,was,were,have been);其他聯系動詞如:become成為,turn變成,go變。其特點是聯系動詞與其後的表語沒有動賓關系,表語多為形容詞或副詞,既,不可能是賓語。
表語:說明主語的狀態、性質、等。可為形容詞、副詞、名詞、代詞、不定式、分詞。當聯系動詞不是be,而其後是名詞和代詞時,多表達『轉變為』之意,注意與動賓關系的區別。
感官動詞多可用作聯系動詞:look well/面色好,sound nice/聽起來不錯,feel good/感覺好,smell bad/難聞
例:Tom is a boy.(Tom是個男孩)/主語為Tom,系詞為be動詞的第三人稱單數is,表語為a boy
There be 結構:
There be 表示『存在有』。這里的there沒有實際意義,不可與副詞『there那裡』混淆。
此結構後跟名詞,表示『(存在)有某事物』
試比較:There is a boy there.(那兒有一個男孩。)/前一個there無實意,後一個there為副詞『那裡』。
二、定語:定語是對名詞或代詞起修飾、限定作用的詞、短語或句子,漢語中常用『……的』表示。
定語通常位於被修飾的成分前。若修飾some,any,every,no構成的復合不定代詞時,(如:something、nothing);或不定式、分詞短語作定語、從句作定語時,則定語通常置後。副詞用作定語時須放在名詞之後。
形容詞作定語:
The little boy needs a blue pen.(little修飾名詞boy;blue修飾名詞pen.)/小男孩需要一支蘭色的鋼筆。
Tom is a handsome boy./Tom是個英俊的男孩。
There is a good boy./有個乖男孩。
數詞作定語相當於形容詞:
Two boys need two pens./兩個男孩需要兩支鋼筆。
The two boys are students./這兩個男孩是學生。
There are two boys in the room./房間里有兩個男孩。
代詞或名詞所有格作定語:
His boy needs Tom's pen./他的男孩需要Tom的鋼筆。
His name is Tom./他的名字是湯姆。
There are two boys of Toms there./那兒有Tom家的兩個男孩。
介詞短語作定語:
The boy in the classroom needs a pen of yours./教室里的男孩需要你的一支鋼筆。
The boy in blue is Tom./穿蘭色衣服的孩子是湯姆。
There are two boys of 9,and three of 10./有兩個9歲的,三個10歲的男孩。
名詞作定語:
The boy needs a ball pen./男孩需要一支圓珠筆。
It is a ball pen./這是一支圓珠筆。
There is only one ball pen in the pencil box./這鉛筆盒裡只有一支圓珠筆。
副詞作定語:
The boy there needs a pen./那兒的男孩需要一支鋼筆。
The best boy here is Tom./這里最棒的男孩是Tom。
不定式作定語:
The boy to write this letter needs a pen./寫這封信的男孩需要一支鋼筆。
The boy to write this letter is Tom./將要寫這封信的男孩是湯姆。
There is nothing to do today./今天無事要做。
分詞(短語)作定語:
The smiling boy needs a pen bought by his mother./那個微笑的男孩需要一支他媽媽買的鋼筆。
The pen bought by her is made in China./她買的筆是中國產的。
There are five boys left./有五個留下的男孩。
定語從句:
The boy who is reading needs the pen which you bought yesterday./那個在閱讀的男孩需要你昨天買的鋼筆。
The boy you will know is Tom./你將認識的男孩叫湯姆。
There are five boys who will play the game./參加游戲的男孩有五個。
協助主要動詞構成謂語動詞片語的詞叫助動詞(Auxiliary Verb)。被協助的動詞稱作主要動詞(Main Verb)。
助動詞自身沒有詞義,不可單獨使用,例如:
He doesn't like English. 他不喜歡英語。
(doesn't是助動詞,無詞義;like是主要動詞,有詞義)
2) 助動詞協助主要動詞完成以下功用,可以用來:
a. 表示時態,例如:
He is singing. 他在唱歌。
He has got married. 他已結婚。
b. 表示語態,例如:
He was sent to England. 他被派往英國。
c. 構成疑問句,例如:
Do you like college life? 你喜歡大學生活嗎?
Did you study English before you came here? 你來這兒之前學過英語嗎?
d. 與否定副詞not合用,構成否定句,例如:
I don't like him. 我不喜歡他。
e. 加強語氣,例如:
Do come to the party tomorrow evening. 明天晚上一定來參加晚會。
He did know that. 他的確知道那件事。
3) 最常用的助動詞有:be, have, do, shall, will, should, would
Ⅷ 英語常用語法
1. 名詞
名詞可以分為專有名詞(Proper Nouns)和普通名詞 (Common Nouns),專有名詞是某個(些)人,地方,機構等專有的名稱,如Beijing,China等。普通名詞是一類人或東西或是一個抽象概念的名詞,如:book,sadness等。普通名詞又可分為下面四類:
1)個體名詞(Indivial Nouns):表示某類人或東西中的個體,如:gun。
2)集體名詞(Collective Nouns):表示若干個個體組成的集合體,如:family。
3)物質名詞(Material Nouns):表示無法分為個體的實物,如:air。
4)抽象名詞(Abstract Nouns):表示動作、狀態、品質、感情等抽象概念,如:work。
個體名詞和集體名詞可以用數目來計算,稱為可數名詞(Countable Nouns),物質名詞和抽象名詞一般無法用數目計算,稱為不可數名詞(Uncountable Nouns)。歸納一下,名詞的分類可以下圖表示:
_______________________________________
| |專有名詞 | |
| 名 | | 個體名詞 | |
| | | | 可數名詞 |
| | | 集體名詞 | |
| |普通名詞 | | |
| 詞 | | 物質名詞 | |
| | | | 不可數名詞|
| | | 抽象名詞 | |
一、名詞性從句
名詞性從句主要分為四大類:主語從句、賓語從句、表語從句和同位語從句。
<一>主語從句
1.that引導的主語從句
that引導的主語從句既可以放在句首也可以放在句末,在實際應用中我們常常採用it形式主語的形式。
例句:That he passed the English test is true. 千真萬確,他通過了英語考試。
→It is true that he passed the English test.
2.形式主語的四個主要句型
(1)It + be + 名詞 + that從句
例:It is a pity that…可惜的是
可應用於此句型的名詞還有fact / shame / honor / question等。
(2)It + be + 形容詞 + that從句
例:It is certain that… 很肯定
可應用於此句型的形容詞還有clear / better / natural / important 等。
(3)It + be + 動詞的過去分詞 + that從句
例:It is said that…據說
可應用於此句型的過去分詞還有believed / known / reported等。
(4)It + 不及物動詞 + that 從句
例:It seems that…好像是
可應用於此句型的不及物動詞還有happen / appear 等。
3.wh-引導的主語從句
例句:Where we will go hasn』t been decided. 我們要去哪兒還沒定下來。
<二>賓語從句
1.that引導的賓語從句
that常用來引導賓語從句,通常that可以省略。
例句:He has told me that he will go to Shanghai tomorrow.
他已經告訴我他明天要去上海。
注意:在demand、order、suggest、decide等表示要求、命令、建議、決定等意義的動詞後,that從句常用「(should) + 動詞原形」的結構(參考「虛擬語氣」部分)。
2.wh-引導的賓語從句
例句:I want to know what he has told you.
我想知道他告訴了你什麼。
3.形容詞後面所跟的賓語從句
某些動態形容詞(afraid、confident、aware、certain、sure、doubtful等)在句中做表語時,後面可跟賓語從句。
例句:I am confident that I can get the job.
我有信心我可以得到這份工作。
<三>表語從句
1.that引導的表語從句
基本結構:主語 + 系動詞 + that從句
例句:The fact is that we have lost the game.
事實是我們已經輸了這場比賽。
2.wh-疑問詞引導的表語從句
例句:That is why I tell you the news..
那就是我為什麼告訴你這個消息的原因。
3.從屬連詞as if、because、just as等引導的表語從句
例句:It is because I have ever heard of the story.
那是因為我曾經聽說過這個故事。
<四>同位語從句
同位語從句通常由that引導
可用於同位語從句的名詞有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。
例句:The news that we won the game is exciting.
我們贏得這場比賽的消息令人激動。

Ⅸ 英語的常用語法
常用語法有 一、句型1——主語+謂語
我們知道,一個句子是為了說明一件事(或表達一種感情),最簡單的表達方式,就是「誰,怎麼樣了」。這里的「誰」,就是句子的主語,它的內涵很豐富,可以是人、物、某種行為等。「怎麼樣了」,就是句子的謂語,由動詞充當。主語+謂語,即構成一個最簡單的句子。舉一些簡單的例子:
I dance.
She died.
we agree.
……
二、句型2——主語+謂語+賓語
句型2在句型1的基礎上多了一個賓語,賓語是什麼呢?還是從句子表達事情的角度看,可以理解為「誰,對誰怎麼樣了」。賓語,就是主語藉助一個動作(謂語)作用的一個對象。還是舉一些簡單的例子:
I hate him.
I love you.
I dance with her.(注意,為什麼這里多了一個with,學過動詞那一節的同學肯定知道哦~)
……
三、句型3——主語+謂語+間接賓語+直接賓語
在這個句型里,我們發現謂語後面跟了兩個賓語,直接賓語,就是謂語動詞直接作用的對象,而間接賓語,是指謂語需要先藉助於一個間接的對象,再把動作傳遞到直接賓語身上。
如,I give him a book.(「給」,這個動作,最終作用的對象是「書」,但需要先通過「他」,把「給」這個動作傳遞到書)
注意,如果理解不了這種句型,關系並不大,只有很少一些動詞需要通過接兩個賓語的方式來表達完整的意思,記住這些動詞就行了。
四、句型4——主語+謂語+賓語+賓語補足語
相對於句型2,這種句型中又多了一個賓語補足語,「補足」意思就是補充說明,所以賓語補足語的作用,就是用來補充說明賓語怎麼樣了。
I want you to go with me.(我要你,要你干什麼呢?to go with me,即要你跟我一些走,這個部分就是賓語補足語。)
注意,在這種句型中,補足語可能不是一個具體的單詞。
五、句型5——主語+系動詞+表語
還記得系動詞嗎?我們在動詞那一節也講過哦,這里就不復習了。這個句型,就是在講如何使用系動詞。表語,就是跟在系動詞後面的成分的一個統稱,不用過分在意它是什麼意思。感官類系動詞,其後一般接形容詞;be動詞後一般接名詞(或不定式等)。同樣舉一些最簡單的例子:
It smells good.
She is a teacher.
……
