初中英語(yǔ)語(yǔ)法:英語(yǔ)語(yǔ)法句子種類基礎(chǔ)知識(shí)
句子的種類可分為陳述句、疑問(wèn)句、祈使句和感嘆句。
1. 凡是說(shuō)明一件事情,提出一個(gè)看法,或者表達(dá)一種心情的句子都是陳述句。大多數(shù)的句子都是陳述句,它可以用肯定式和否定式,句末用句號(hào)".",通常用降調(diào)。
掌握陳述句的肯定式和否定式的構(gòu)成及用法。
e.g. We live in Tianjin. (肯定句)我們住在天津。
We don't live in Shanghai. (否定句)我們不住在上海。
注意:(1)在一般現(xiàn)在時(shí)的肯定式中,主語(yǔ)是第三人稱單數(shù)時(shí),動(dòng)詞要改成第三人稱單數(shù)形式。
e.g. John studies Chinese very well.
。2)一般現(xiàn)在時(shí)和一般過(guò)去時(shí)的否定式要加助動(dòng)詞do (does), did.
e.g. I don't like swimming. 我不喜歡游泳。
He doesn't have lunch at home every day. 他每天不在家吃午飯。
They didn't play football yesterday. 他們昨天沒(méi)有踢足球。
2. 掌握一般疑問(wèn)句、特殊疑問(wèn)句、選擇疑問(wèn)句和反意疑問(wèn)句的構(gòu)成、用法和答語(yǔ)。注意在一般現(xiàn)在時(shí)和一般過(guò)去時(shí)的疑問(wèn)句要加助動(dòng)詞do(does), did.
e.g. Do you often speak English at school ? 在學(xué)校你常講英語(yǔ)嗎?
Does she have a brother ? = Has she got a brother ? 她有兄弟嗎?
Did it take you two hours to do your homework last night ?

你父親每天早晨幾點(diǎn)鐘起床?
Why didn't your teacher come to school yesterday ?
昨天你們的老師為什么沒(méi)來(lái)學(xué)校呢?
提出兩種或兩種以上的情況,要求對(duì)方選擇一種,這種疑問(wèn)句叫選擇疑問(wèn)句。結(jié)構(gòu)是:"一般疑問(wèn)句+or+一般疑問(wèn)句",但常把后一部分里面和前一部分相同的成分省略。說(shuō)明or前面部分用升調(diào),后面部分用降調(diào)。
e.g. Is her brother an artist or a doctor ?
她的兄弟是一個(gè)藝術(shù)家還是個(gè)醫(yī)生?
Would you like tea or coffee ?
你愿意喝茶還是喝咖啡?
Shall we go to the cinema on Saturday or on Sunday ?
我們是周六還是周日去電影院?
反意疑問(wèn)句表示提問(wèn)者有一定的主見(jiàn),但沒(méi)把握,希望對(duì)方來(lái)證實(shí)。
注意反意疑問(wèn)句的結(jié)構(gòu)是:肯定的陳述句+否定的疑問(wèn)句(縮略形式)
或:否定的陳述句+肯定的疑問(wèn)句(縮略形式)
兩部分的人稱和時(shí)態(tài)要一致。
特別要注意否定的疑問(wèn)句中的助動(dòng)詞必須縮寫(xiě),主語(yǔ)(最后一個(gè)詞)必須是代詞而不能是名詞。
e.g. Your sister has ever been to Shanghai , hasn't she ?
你姐姐曾經(jīng)去過(guò)上海是嗎?
The boys didn't find anything , did they ?
男孩子們什么也沒(méi)找到/發(fā)現(xiàn),是不是?
在回答反意疑問(wèn)句時(shí),要根據(jù)事實(shí)而定,事實(shí)是肯定的要回答Yes , …,事實(shí)是否定的要回答No, ….
e.g. He isn't going to the meeting , is he ?

Yes , it did. / No , it didn't. 不,下雪了。是的,沒(méi)下雪。
3. 掌握祈使句的肯定式和否定式。祈使句沒(méi)有主語(yǔ)。指讓對(duì)方做某事,動(dòng)詞要用原形。表示請(qǐng)求,命令、建議等。
e.g. Go back to your seat , please. 請(qǐng)回到你的座位上去。

。╨et's是含有第一人稱主語(yǔ)的祈使句)

注意:否定形式是Let's (us , me)+not +動(dòng)詞原形
e.g. Let's not say anything about it.
對(duì)于這件事,咱們什么也不要說(shuō)了。
4. 表示喜怒哀樂(lè)等強(qiáng)烈感情時(shí)用感嘆句,理解由What和How引導(dǎo)的感嘆句的語(yǔ)序和感嘆句的使用方法。How和What與所修飾的詞放在句首,其它部分用陳述句語(yǔ)序。在口語(yǔ)中謂語(yǔ)常省略。
。1)how作狀語(yǔ),修飾形容詞,副詞或動(dòng)詞
結(jié)構(gòu):How+形容詞/副詞+主語(yǔ)+謂語(yǔ)
How nice the flowers are ! 花多漂亮!

。2)what作賓語(yǔ),修飾名詞(名詞前可有其他定語(yǔ)),單詞可數(shù)名詞前要加不定冠詞a(an).

賓語(yǔ)從句的時(shí)態(tài)呼應(yīng)是:主句的時(shí)態(tài)是一般現(xiàn)在時(shí),從句可以是任何一個(gè)時(shí)態(tài)。
如果主句的時(shí)態(tài)是一般過(guò)去時(shí),從句必須是過(guò)去時(shí)態(tài)的一種形式。

狀語(yǔ)從句的時(shí)態(tài)要與主句時(shí)態(tài)相互呼應(yīng)。但要注意以as soon as , when , until等引導(dǎo)的時(shí)間狀語(yǔ)從句表示將來(lái)的動(dòng)作時(shí),從句要用一般現(xiàn)在時(shí)表示將來(lái)。

以if引導(dǎo)的條件狀語(yǔ)從句假設(shè)的是將來(lái)的動(dòng)作,主句用一般將來(lái)時(shí),從句用一般現(xiàn)在時(shí)。
e.g. He will come to see me if he has time. 如果條件狀語(yǔ)從句放在賓語(yǔ)從句中,時(shí)態(tài)則依照賓語(yǔ)從句的要求而變。
e.g. My mother said she would buy me a book if I studied hard.
我母親說(shuō)如果我努力學(xué)習(xí),她要給我買一本書(shū)。
以because引導(dǎo)的原因狀語(yǔ)從句不可能和so一起連用。
e.g. He didn't come to school yesterday because he was ill.
他昨天沒(méi)來(lái)學(xué)校,因?yàn)樗×恕?/p>
注意防止出現(xiàn)以下錯(cuò)誤:
A. I'm sure he'll ring you up if he will come back.
從句時(shí)態(tài)錯(cuò)誤,will come應(yīng)該改為comes.
B. Because he was tired , so he went to bed very early.
中文習(xí)慣用"因?yàn)椤浴?quot;,但在英語(yǔ)中because不能和so同時(shí)使用,應(yīng)該去掉其中的一個(gè)。
