1、精選優(yōu)質文檔-傾情為你奉上 句子的種類【名師點睛】一. 陳述句的構成形式及基本用法1. 陳述句： 陳述句是用來陳述一個事實或表達說話人看法（包括肯定和否定）的句子。通常用降調，句末用句號“.”。Tom has a new car. The flower isnt beautiful. 2. 陳述句否定式的構成(1) 如果肯定陳述句的謂語部分含有助動詞、情態(tài)動詞或連系動詞be，則只需在這些動詞后加not即可構成否定式。 He is playing the guitar.（肯定） He is not playing the guitar.（否定） We can get there before d

2、ark.（肯定） We cant get thee before dark.（否定） (2) 如果陳述句的謂語動詞是實義動詞，而其中又沒有情態(tài)動詞或助動詞時，則需根據人稱和時態(tài)在該實義動詞前加dont, doesnt或didnt。同時把該實義動詞變?yōu)樵巍?He plays the violin well.（肯定） He doesnt play the violin well.（否定） She won the game.（肯定） She didnt win the game.（否定） (3) 如果句子是there be結構或謂語動詞是have（有），除了be和have之后加not之外，句中如果

3、有some要變?yōu)閍ny。例如：There is some water in the cup. There is not any water in the cup.He has some books. He has not any books.(4) 除not以外，否定詞no, never, nothing, nobody, few等也可構成否定句。例如：There is something wrong with his bike. There is nothing wrong with his bike.I have seen the film. I have never seen the f

4、ilm.二. 祈使句的構成形式及基本用法 祈使句是用來表示命令、請求、建議、號召等的句子，謂語動詞用原形，句末用感嘆號“！”或句號“.”。朗讀時一般用降調。1. 肯定的祈使句：（1）祈使句主語是you時，you常省略，但如果要特別強調對方或表達某種強烈的情緒時可以有主語或稱呼語。 Be quiet. You be quiet!（2）“Do+祈使句”表示一種強烈的感情或請求，do起強調作用。 Do come back at once! Do be careful.（3）please用在祈使句中可以表示一種客氣的語氣，但please用在句末時，必須用逗號與其余部分分開。 Open the wind

5、ow, please.（4）Let引導祈使句時，后面需跟上人稱代詞或稱呼語，人稱代詞一般只用第一、第三人稱。 Let Jack wait a minute. Lets go to school.（5）在祈使句中，Lets和 Let us是有區(qū)別的。Lets包括說話者，而Let us不包括聽話者在內。這點從反意疑問句時可明顯看出。 Lets go skating, shall we?（表示內部的建議） Let us try again, will you?（表示向別人發(fā)出請求） 2. 否定祈使句通常以Dont或Never開頭。其結構通常是：“Dont(Never)+動詞原形+其他成分” 例如：

6、Dont do that again! Never leave todays work for tomorrow! Dont be late next time!三. 一般疑問句、特殊疑問句、選擇疑問句、反意疑問句的構成形式及基本用法1. 一般疑問句： （1）一般疑問句的肯定形式 一般疑問句一般是指以助動詞、情態(tài)動詞、be動詞或have（有）開始，通常要求以yes，或no來回答的疑問句，一般疑問句讀時通常用升調。 Do you know Mr. Smith? Can you swim? （2）一般疑問句的否定結構 在一般疑問句的否定結構中，把副詞not放在一般疑問句的主語之后。但如果用not的

7、簡略形式-nt，則須將-nt與一般疑問句句首的be, have，助動詞或情態(tài)動詞寫在一起。在實際運用中，一般都采用簡略式。 Are you not a football fan? Arent you a football fan? Will she not like it? Wont she like it? 與漢語不同的是，英語一般疑問句否定結構的答語是否定還是肯定，全由答語的否定或肯定來決定。若答語是肯定的，則用yes加肯定結構；若答語是否定的，則用no加否定結構。 Arent you a football fan? 你不是足球迷嗎？ Yes, I am.No, I am not. Won

8、t she like it? Yes, she will. No, she wont. 2. 特殊疑問句特殊疑問句由“疑問代詞或疑問副詞+一般疑問句”構成，句子一般用倒裝語序，但如果主語是疑問代詞或由疑問代詞修飾時，用陳述句的語序。特殊疑問句不能用yes或no回答，讀時用降調。例如：Who is on duty today? How long have you been in Beijing?What time do you get up every morning?What must I do now?常用的特殊疑問句詢問內容 疑問詞或句型 例 句 回 答 職業(yè)，身份 what What i

13、gh is the tower? Shes 1.73 metres.Its 450 metres. 3. 選擇疑問句： 選擇疑問句是說話者提出兩種或兩種以上的不同情況，讓對方選擇回答的疑問句。其結構是“疑問句+選擇部分”。選擇部分由or連接，or前面的部分讀升調，or后面的部分讀降調。 選擇疑問句不能用yes或no回答，而必須具體的選擇答復。 Is your bag yellow or black? Its black.。 Would you like some tea or coffee? Either will do.。 Which do you like better, singing

14、or dancing? I like dancing better.4. 反意疑問句： 反意疑問句是指在陳述句之后附加一個意思與之相反的簡短問句，問對方是否贊同的疑問句。附加問句的否定式必須縮寫。（1）肯定的陳述句后跟否定的附加問句，否定的陳述句后跟肯定的附加問句。 I am your teacher, arent I? He didnt study hard, did he?（2）如果陳述句中含有否定副詞never（從不，決不），hardly（幾乎不）或其他表示否定代詞或形容詞，如nothing, none no one, nobody, neither, few, little等，則附加問

15、句只能用肯定式。如： They hardly write to each other, do they? He has found nothing, has he? Few people knew the secret, did they? （3）當反意疑問句是“否定陳述句+肯定附加問句”時，英語與漢語的回答習慣存在差異。英語回答時只看實際情況，若答語的具體內容是肯定的就用“Yes+肯定結構”，答語的具體內容是否定的就用“No+否定結構”，而譯成漢語時，則必須把yes譯“不是”，把no譯成“是的”。 -You wont be away for long, will you? 你不會離開太久，是

16、嗎？ -Yes, I will.不，我會離開很久。 -No, I wont.是的，我不會離開很久。 -I dont think shell come by bike, will she? 我認為她不會騎自行車，會嗎？ -Yes, she will.不，她會騎自行車來。 -No, she wont.是的，她不會騎自行車來。四. 由what, how引導的感嘆句的構成形式、用法及區(qū)別感嘆句是表示喜、怒、哀、樂以及驚異等感情的句子。句末用感嘆號“！”，讀時用降調，感嘆句往往由what或how引導，what修飾名詞，how修飾形容詞，副詞或動詞。1. what引導的感嘆句：（1）what + a/an
