關(guān)于英語語法句子種類2
只有一個主語 (或并列主語)和一個謂語(或并列謂語)的句子叫簡單句。
1.根據(jù)句子的結(jié)構(gòu),簡單句可分為5種:
(1)S+V
(2)S+V+O
(3)S+V+P
(4)S+V+InO+DO
(5)S+V+O+C
此外,還有 there be句型,這一句型具有就近原則,也即謂語動詞用單數(shù)還是復(fù)數(shù)要看接近于be動詞的那個名詞。
2.根據(jù)句子的功能,簡單句可分為4類:
陳述句、疑問句、祈使句、感嘆句
(一)陳述句
1.肯定式
2.否定式
(1)加not構(gòu)成的否定句
(2)由no, hardly, never, nobody, nothing等構(gòu)成的否定句。
其中兩者的全部否定用 neither或nor,部分否定用both +not.
如: Neither of them knows French.
Both of them don't know French.
三者或三者以上的全部否定用 none, nothing, nobody, no one等,部分否定用all, many, every加not構(gòu)成
如: None of these answers are right.All these books are not mine.
(3)在某些句子中,按語意應(yīng)放在that從句中的否定詞not被移前到主句的謂語動詞中,這種否定提前的情況用于think, believe, suppose等動詞,如:I don't believe it will be very cold tomorrow.
(二)疑問句
按結(jié)構(gòu)可分為四種
1.一般疑問句:
(1)用Yes,No來回答的疑問句。
(2)往往把be,助動詞,情態(tài)動詞置于句首。
(3)在一般疑問句中,如果提問人對答案沒有肯定或否定的意向,句中常用非肯定詞,如:
Is there anything wrong with your car?
如果提問人對答案有肯定的意向,即希望得到肯定的回答,則在該用非肯定詞的地方用肯定詞,如: Would you like some drink?因此,在招待客人或向人表示樂意提供幫助時,通常用some代替any。
2.特殊疑問句:
用疑問代詞或疑問副詞提問的句子,不用Yes,No回答。
(1)疑問詞作句子的賓語、狀語、表語或修飾這三種成份時,用疑問詞+一般疑問句,
如: When will you go?
(2)疑問詞作主語或主語的定語時,與陳述句的順序相同,
如:
Whose father works in Shanghai?
Who is on duty today?
3.反意疑問句
(1)構(gòu)成:陳述句 + 簡略問句
肯定 否定
否定 肯定
簡略問句的主語與陳述句保持一致,只能用人稱代詞 (there除外),簡略問句的謂語動詞也與陳述句保持一致,如果是否定,一定要用簡寫。如:
Jim isn't a student, is he?/There are some books in it, aren't there?
(2)陳述部分I'm...結(jié)構(gòu),疑問部分一般用aren't I,如:
I'm late, aren't I?
(3)陳述句中有l(wèi)ittle, few, no, never, nothing, nobody, hardly等詞表示否定時,簡略問句用肯定。
(4)陳述句中有指物的不定代詞nothing, something, anything時,簡短問句中用代詞it,陳述句中有指人的不定代詞everyone, no one, someone, everybody, nobody, anybody時,簡短問句中用代詞he或they,如:Everyone is here, aren't they/isn't he?
(5)陳述句的主語是指示代詞this, that等時,疑問部分的主語在形式上與前者不同,但在邏輯上卻與前者一致,如:This is very important, isn't it?
(6)陳述部分如果是“I (don't) think (believe, suppose...)+賓語從句”時,疑問部分中的動詞和主語應(yīng)與賓語從句中的主語和動詞保持一致,如:I don't believe she knows it, does she?
(7)含有情態(tài)動詞must的句子表示猜測時,疑問部分與must后面部分一致,不能用mustn't,如:You must be tired, aren't you?當(dāng)must表示“有必要”時,疑問部分用needn't,如:You must go home right now, needn't you?當(dāng)mustn't表示禁止時,疑問部分一般用must,如:
You mustn't walk on grass, must you?
(8)祈使句的反意疑問句
肯定祈使句 +will you/won't you?
否定祈使句 +will you?
Let's...+shall we?(包括對方)
Let us...+will you?(不包括對方)
(9)感嘆句的反意疑問句一律用否定式,并用be的一般現(xiàn)在時,如:
What a lovely girl, isn't she?
(10)前面否定后面肯定的反意疑問句在回答時,需根據(jù)其實際情況,實際情況是肯定的,則用Yes+肯定結(jié)構(gòu),實際情況是否定的,則用No+否定結(jié)構(gòu),如:
— You can't speak English, can you?
— Yes, I can(不,我會的)
(11)關(guān)于“'d”和“'s”
注意比較:
He'd like a cup of tea, wouldn't he?/You'd better go now, hadn't you?
He's never late for school, is he?/He's never been there, has he?
4.選擇疑問句:選擇疑問句是用or連接詢問的兩部分,以供選擇,答案必須是完整的句子或其省略形式,不能用Yes或No回答,如:Are you Jim or Tom?I'm Tom.
(三)祈使句
用以表示命令、請求或建議,主語通常省略。
肯定式謂語用動詞原形,否定式用“ Don't (Never)+動詞原形”,Stand up, please./Don't be afraid.
(四)感嘆句
用以表示快樂、痛苦等強烈感情的句子稱為感嘆句。
感嘆句有用 how或what開頭的兩種形式。
1.How開頭的感嘆句
(1) How+形容詞(副詞)+主語+謂語。如:
How beautiful the flower is!
(2) How修飾動詞,句型是“How+主+謂”,如:
How I wish I could hear Beethoven himself play it!
(3) How+形容詞(副詞),省略主語和謂語,如:
How interesting(it is)!
2.what開頭的感嘆句:
(1)What+(a)+形容詞+名詞+主語+謂語,如:
What a nice horse it is! What fine weather! What good news!
(2)What(a)+名詞!
What a pity!
二、句子的成分
組成句子的各個部分叫句子成分。句子的各種成分包括主語、謂語、表語、賓語、定語、狀語等。
主語 句子的主體,發(fā)出動作的人或物,表示所說的是誰或是什么。主語一般放在句首,特殊句型中,在句末,由名詞、代詞或相當(dāng)于名詞的詞或短語充當(dāng)。如:
He was born in a small village.他出生在一個小村莊。
謂語 說明主語的動作特征狀態(tài)等,由動詞或動詞短語構(gòu)成。如:
She told me about that story.
主謂一致:主語和謂語必須在人稱、數(shù)兩方面保持一致。主謂一致的關(guān)鍵是判斷主語是單數(shù)還是復(fù)數(shù)。
1. 一般情況主語的數(shù)比較明確 如:
His mother works in a office.她媽媽在辦公室工作。
2. and 連接的兩個或兩個以上名詞或代詞做主語時,謂語動詞用復(fù)數(shù)形式。如:
Linda and Susan are from America.琳達和蘇珊來自美國。
3. each, either, neither, another做主語時,謂語動詞用單數(shù)。如:
Neither of us has been to France.我們兩個都沒去過法國。
4. 由some, any, no, every構(gòu)成的合成代詞作主語時,謂語用單數(shù)。如:
No one knows his phone number.沒有人知道他的電話號碼。
5. 由either…or…;neither…nor…;not only…but also…構(gòu)成的合成代詞作主語時,謂語與距離最近的主語保持一致。如:
Not only my friends but also my sister agrees with me.我的朋友和我的妹妹都贊同我。
6. 集合名詞people, police等作主語時,位于用復(fù)數(shù)。如:
The people were surprised to see him dancing in the street.人們很驚訝的看他在街上跳舞。
7. 集合名詞family, class等作主語時,如看作整體,謂語用單數(shù)。如強調(diào)個體,則謂語用復(fù)數(shù)。如:
My family has lived here for twenty years. 我們家在這里住了20年了。
His family were watching TV while the phone rang.電話響起時,他們?nèi)以诳措娨暋?/p>
8. some, any, none, half 作主語時,謂語動詞的單、復(fù)數(shù)形式視情況而定。如:
Half of the students are boys. 一半學(xué)生是男生。
Half is enough.一半就夠了。
9. 時間、距離、重量、數(shù)量、價值等名詞附屬作主語時,謂語動詞常用單數(shù)。如:
Ten years is not a long time.十年不算太久。
表語 用來說明主語的身份、特征、狀態(tài)等,位于連系動詞后??勺鞅碚Z的有名詞、代詞、形容詞、數(shù)詞、副詞、動詞不定式、介詞短語、分詞短語及從句等。如:
Is this pen yours? 這筆是你的嗎?
賓語 是動作的承受者。及物動詞及相當(dāng)于及物動詞的短語后都必須帶賓語。名詞、代詞、動名詞、不定式和從句均可作賓語。如:
The little boy waited his mother to buy him hamburgers.這個小男孩想讓他媽媽給他買漢堡。
有些動詞需要兩個同等的賓語,即直接賓語和間接賓語。直接賓語一般指動作的承受者,間接賓語指動作所向的或所為的人或物(多指人)。后接雙賓語的動詞有:answer, bring, buy, deny, do, fetch, find, get, give, hand, keep, leave, lend, make, offer, owe, pass, pay, play, promise, read, refuse, save, sell, send, show, sing, take, teach, tell, throw, wish, write等。間接賓語一般于直接賓語連用,通常放在直接賓語之前。如:
She made her son a birthday cake.她給她兒子做了一個生日蛋糕。
They sent me a letter.他們給我寄了一封信。
定語 修飾名詞或代詞的句子成分??梢宰龆ㄕZ的有名詞、代詞、數(shù)詞、形容詞、副詞、動詞不定式、介詞短語、動名詞、分詞短語及從句等。形容詞作定語放在名詞之前,副詞或副詞短語時常放在名詞后。如:
What a lovely day! 多好的日子啊!
I have a lot of work to do. 我有許多工作要做。
狀語 用來修飾動詞、形容詞、副詞的句子成分稱為狀語。狀語用來說明時間、地點、條件、原因、方式、程度、目的、結(jié)果等??捎米鳡钫Z的有副詞、不定式短語、分詞短語、介詞短語及從句等。如:
