學習英語四級語法之前首先要學習句子，因為句子是人類語言的核心，通過對句子的分析理解，可以更好的掌握語法。下面是小編給大家分享的相關(guān)內(nèi)容，大家可以作為參考。 一、基數(shù)詞 1)基數(shù)詞寫法和讀法： 345　three hundred and forty-five; 2)基數(shù)詞一般是單數(shù)形式，但下列情況，常用復數(shù)： a. 與of 短語連用，表示概數(shù)，不能與具體數(shù)目連 用，如scores of people 指許多人; b.　在一些表示"一排"或"一組"的詞組里; 如：They arrived in twos and threes.　他們?nèi)齼蓛傻牡竭_了。 c. 表示"幾十歲"; d. 表示"年代

語四級的過程中，積累單詞和掌握語法是最重要的。下面是小編給大家分享的英語四級語法

備考英語四級的過程中，單詞的積累和語法的掌握是學習的重中之重。下面是小編給大家分享的四級語法知識點，大家可以作為學習的參考。 1. 某些動詞后要接不定式 某些及物動詞后只能接不定式作賓語，其中最常用的動詞有agree， afford， arrange， appear， ask， attempt， care， choose， continue， decide， demand， desire， determine， expect， fail， fear， forget， hate， hesitate， hope， intend， learn， like， love， manage， mean

of the moon.　地球是月球的49倍。 c. 主語+謂語+倍數(shù)(分數(shù))+ 形容詞(副詞)比較級+ than… The grain output is 8 percent higher this year than that of last year.今年比去年糧食產(chǎn)量增加8%。 d. 還可以用by+倍數(shù)，表示增加多少倍 The production of grain has been increased by four times this year.今年糧食產(chǎn)量增加了4倍。 （2）分數(shù)表示法 構(gòu)成：基數(shù)詞代表分子，序數(shù)詞代表分母。分子大于1時，分子的序數(shù)詞用單數(shù)，分母序數(shù)詞用復數(shù)： 1/3 one-third ; 3/37 three and three-sevenths.

過去式; 表示將來不可能實現(xiàn)的愿望用“would/could+動詞原形”; 表示過去不可能實現(xiàn)的愿望時用“had+過去分詞”。如： I wish I were better-looking. 要是我長得再漂亮些就好了。 I wish I had met the film star just now. 我要是剛才遇到那位電影明星該多語氣主要體現(xiàn)在三個方面：基本用法，各自為政，以及含蓄之美。下面是小編給大家整理的語法好啊! I wish I would be a solider. 我想當一名軍人。 虛擬語氣在狀語從句中的應用 1. if only的條件狀語從句中的虛擬語氣 if only 與 I wish一樣，也用于表示與事實相反的愿望，其后所接虛擬語氣的時態(tài)與 wish 后所接時態(tài)的情況相同。如： If only the player had had more courage! 這位選手再多有一些勇氣就好了。 If only Daisy would go with me! 黛茜要是愿意和我一起去就好了! 想要學好英語，需要大量的積累單詞和掌握語法。以上就是英語四級語法知識，希望可以給大家在學習的時候帶來四級幫助。

語學習需要積累的是詞匯，你需要搞明白的就是語法，語法能指人，none既可以指人，也可以指物，none后面還可以接of; eg：No one failed the examination. None of the students failed the examination. 6. it 的用法 (1)指代人，通常用于口語中; (2)書面語： ① it 用來指代時間、距離、溫度、天氣等 eg：It’s three years since I saw him. ② it 用來前指或者后指 eg：I’ve lost my book. Where

語四級用到一個形容詞，而selectively明顯是一個副詞。 6、名詞可數(shù)與不可數(shù)的錯誤。 例如：In modern society, people are under various pressures(誤) In modern society, people are under various kinds of pressure. (正) pressure是一種無形的但是有很多種類的事物，所以不能直接在后面加復數(shù)s，但是要形容他多，各種各樣后面加一個種類kinds of 就正確表達出了復數(shù)形式。 7、及物動詞與不及物動詞的誤用。 例如：The traffic accident was taken place at the junction of two highways. (誤) The traffic accident took place at the junction of two highways. (正) 發(fā)生是一個主動的過程，沒有什么事是被發(fā)生的，所以不能用was taken place 。 8、情態(tài)動詞的誤用。 例如：They should spent much time. (誤) They should spend

給誰?(作介詞賓語，置句首) To whom did you speak on the campus? 你在校園里和誰講話了?(作介詞賓語，置介詞 后，不能用who取代。) 說明3： 疑問代詞用于對介詞賓語提問時，過去的文體中介詞和疑問代詞通常一起放在句首，現(xiàn)代英語中，疑問代詞在句首，介詞在句未，例如： For what do most people live and work? 大部分人四級的時候?qū)τ谒募壵Z法里的疑問代詞不是很了解，下面是小編給大家分享的大學英語四級語法生活和工作的目的是什么?(舊文體) What are you looking for? 你在找什么?(現(xiàn)代英語) 說明4： 疑問代詞還可引導名詞性從句，例如： I can't make out what he is driving at. 我不知道他用意何在。 Can you tell me whose

四級考試中取得高分，語法不能忽視。因為語法已經(jīng)滲透到各種題型當中去了。聽力中有語法、閱讀理解中也有語法行時用在一起表示動作正在和一直在延續(xù)進行。 三、不定式 動詞不定式是非謂語動詞的重要組成部分，在六級考試中非謂語動詞部分是一個重點。常跟不定式的動詞有 agree, fail，promise，afford，ask，happen，resolve，te, seek, long，threaten，claim，manage，trouble ,consent, neglect, try，decide ，offer，undertake，demand，eer，determine，prepare，want， pretend，wish，endeavor，proceed，struggle 等，在了解了加 to 的單詞之后，我們來看一看在什么情況下單詞 to 可以被省略。 l、在一般助動詞或者情態(tài)動詞之后 to 可以被省略。 2、在動詞 make，let， watch，see …之后作賓語的時候， to 可以被省略。 3、在 why 和 why not 之后 to 可以被省略，如： Why spend such a lot of time? 為什么花這么多時問 ? 和 Why not go right now? 為什么 不 現(xiàn)在去呢 ? 以上就是英語四級語法知識，希望可以給大家學習帶來四級考試中取得高分，語法不能忽視。因為語法已經(jīng)滲透到各種題型當中去了。聽力中有語法、閱讀理解中也有語法，下面是小編給大家分享的四級語法知識，大家可以作為學習的參考。 一、從句 從句分為定語從句、狀語從句、名詞性從句。其中定語從句又可以分為限制性定語從句及非限制性定語從句。在復習從句的時候要注意它們的引導詞以及限制條件。 1、在非限制性定語從句中 which 可以作主 語， as 則一般不用作主語; 2、在狀語從句中用來表示“一……就”的習慣搭配有 hardly / scarely ...， no sooner … than ; 3、可以引導原因狀語從句的符合連詞有 in that，now that 。 seeing that，considering that …等; 4、在名詞性從句中應該注意 whether 和 if 的區(qū)別。 Whether 引導的從句可以放在句首，而 if 則不行; if 引導的從句可以有否定的形式，而 whether 從句就不行; whether 和 or not 可以連起來用，但 if 和 0r not 就不能連用， or not 必須放在句末。 看一道 例題： And _______fifty years ago “being employed” meant working as a factory labour or as a farmhand，the employee of today is increasingly a middle class person with a substantial formal education，holding a professional or management job requiring intellectual and technical skills . B. which D. that 拋開前面的從句先不看，后面主句的意思是今天雇員越來越多地成為中產(chǎn)階級，受過扎實的正規(guī)教育，擔任需要智力和技能的專業(yè)工作或管理工作。從句的意思是 50 年前，被雇傭就意味著在工廠或農(nóng)場里當勞力。顯然前后句所表達的并非同一個概念，空格中應該填入表示讓步的連詞，引導從句。 when 在這里的用法比較特殊，它可以代替 although ，所以正確答案是 A 。又如： You describe the boy as stupid，when in fact he is very smart .你把那個男孩說得很笨，但是實際上他非常聰明。 二、時態(tài) 英語中最常見以及?？嫉臅r態(tài)是一般現(xiàn)在時、一般過去時、一般將來時、現(xiàn)在完成時、現(xiàn)在進行時等八種。這些時態(tài)我們幾乎在每次使用英語的時候，無論是說話或者是寫作，都會遇到，一般用法早已熟記于心了，復習的時候只要留心他們的一些特殊用法，這里以現(xiàn)在完成時和現(xiàn)在 ( 完成 ) 進行時為例。 現(xiàn)在完成時的一些特殊用法： l、在 this is(it is)the first time that …句型中，從句常用完成時態(tài)。如： It is the second time he has been out with her . 2、 have been t0 與 have gone to 的區(qū)別。前者側(cè)重表示經(jīng)歷過，說話人可能已經(jīng)不在那個地方，或者已經(jīng)回來了。而后者表示已經(jīng)去了那里，說話的時候可能還在那里，或者在去那里的路上。 3、用在時間或條件狀語從句中，表示將來某個動作發(fā)生之前業(yè)已完成的動作，如： I ll go to see the film as soon as I have finished my homework .我一做完作業(yè)就去看電影。其中做完作業(yè)的動作在看電影動作之前完成。 4、 when 引起的疑問句中一般不用現(xiàn)在完成時，因為詢問者關(guān)心的是事情發(fā)生的具體時間現(xiàn)在 ( 完成 ) 進行時除了表示正在進行的動作之外，還主要有以下的用法： l、與頻度副詞如 always，continually，constantly 。 forever 等狀語連用，表示經(jīng)常發(fā)生的，具有持續(xù)性動作的事情，或者表示不滿，或者心中抱怨。如： She is always thinking 0f others .她總是替別人著想。 2、與 hope、 wonder、 want 等詞連用，表示婉轉(zhuǎn)的口氣，例如： I m wondering if you could lend me some money . 3、另外還因該注意到，表示心理狀態(tài)、情感、感覺、所有關(guān)系及特征等狀態(tài)的動詞一般不用進行時，如： smell，taste，sound，notice， hate，like，love，believe，understand，Want，seem，appear，contain，see ，hear，agree，belong 等。 看一道 相關(guān)的例題： The company _______a rise in salary for ages 。 but nothing has happened yet promised been promising promising D. promised 這個句子的意思是說公司長期以來一直答應增加工資，但依然毫無結(jié)果。句子中有時間狀語 for ages 。它常與現(xiàn)在完成時連用，這種時態(tài)強調(diào)動作的持續(xù)性，表示現(xiàn)在以前的這一段時間里一直在做而且現(xiàn)在仍然在進行的一個動作。另外， but 以后的從句也表示了現(xiàn)在完成時，說明和現(xiàn)在有關(guān)。正確答案應該是 B ，可以和現(xiàn)在完成進行時連用的表示一段時間的狀語還有 for a year，these few early morning，since yesterday，for about two hours 等。把它們與進行時用在一起表示動作正在和一直在延續(xù)進行。 三、不定式 動詞不定式是非謂語動詞的重要組成部分，在六級考試中非謂語動詞部分是一個重點。常跟不定式的動詞有 agree, fail，promise，afford，ask，happen，resolve，te, seek, long，threaten，claim，manage，trouble ,consent, neglect, try，decide ，offer，undertake，demand，eer，determine，prepare，want， pretend，wish，endeavor，proceed，struggle 等，在了解了加 to 的單詞之后，我們來看一看在什么情況下單詞 to 可以被省略。 l、在一般助動詞或者情態(tài)動詞之后 to 可以被省略。 2、在動詞 make，let， watch，see …之后作賓語的時候， to 可以被省略。 3、在 why 和 why not 之后 to 可以被省略，如： Why spend such a lot of time? 為什么花這么多時問 ? 和 Why not go right now? 為什么 不 現(xiàn)在去呢 ? 以上就是英語四級幫助。
