I wish I would be a solider. 我想当一名军人。 虚拟语气在状语从句中的应用 1. if only的条件状语从句中的虚拟语气 if only 与 I wish一样，也用于表示与事实相反的愿望，其后所接虚拟语气的时态与 wish 后所接时态的情况相同。如： If only the player had had more courage! 这位选手再多有一些勇气就好了。 If only Daisy would go with me! 黛茜要是愿意和我一起去就好了! 想要学好英语，需要大量的积累单词和掌握语法。以上就是英语四级语法知识，希望可以给大家在学习的时候带来四级帮助。

语学习需要积累的是词汇，你需要搞明白的就是语法，语法能指人，none既可以指人，也可以指物，none后面还可以接of; eg：No one failed the examination. None of the students failed the examination. 6. it 的用法 (1)指代人，通常用于口语中; (2)书面语： ① it 用来指代时间、距离、温度、天气等 eg：It’s three years since I saw him. ② it 用来前指或者后指 eg：I’ve lost my book. Where

语四级用到一个形容词，而selectively明显是一个副词。 6、名词可数与不可数的错误。 例如：In modern society, people are under various pressures(误) In modern society, people are under various kinds of pressure. (正) pressure是一种无形的但是有很多种类的事物，所以不能直接在后面加复数s，但是要形容他多，各种各样后面加一个种类kinds of 就正确表达出了复数形式。 7、及物动词与不及物动词的误用。 例如：The traffic accident was taken place at the junction of two highways. (误) The traffic accident took place at the junction of two highways. (正) 发生是一个主动的过程，没有什么事是被发生的，所以不能用was taken place 。 8、情态动词的误用。 例如：They should spent much time. (误) They should spend

给谁?(作介词宾语，置句首) To whom did you speak on the campus? 你在校园里和谁讲话了?(作介词宾语，置介词 后，不能用who取代。) 说明3： 疑问代词用于对介词宾语提问时，过去的文体中介词和疑问代词通常一起放在句首，现代英语中，疑问代词在句首，介词在句未，例如： For what do most people live and work? 大部分人四级的时候对于四级语法里的疑问代词不是很了解，下面是小编给大家分享的大学英语四级语法生活和工作的目的是什么?(旧文体) What are you looking for? 你在找什么?(现代英语) 说明4： 疑问代词还可引导名词性从句，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

四级考试中取得高分，语法不能忽视。因为语法已经渗透到各种题型当中去了。听力中有语法、阅读理解中也有语法行时用在一起表示动作正在和一直在延续进行。 三、不定式 动词不定式是非谓语动词的重要组成部分，在六级考试中非谓语动词部分是一个重点。常跟不定式的动词有 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 的单词之后，我们来看一看在什么情况下单词 to 可以被省略。 l、在一般助动词或者情态动词之后 to 可以被省略。 2、在动词 make，let， watch，see …之后作宾语的时候， 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? 为什么花这么多时问 ? 和 Why not go right now? 为什么 不 现在去呢 ? 以上就是英语四级语法知识，希望可以给大家学习带来四级考试中取得高分，语法不能忽视。因为语法已经渗透到各种题型当中去了。听力中有语法、阅读理解中也有语法，下面是小编给大家分享的四级语法知识，大家可以作为学习的参考。 一、从句 从句分为定语从句、状语从句、名词性从句。其中定语从句又可以分为限制性定语从句及非限制性定语从句。在复习从句的时候要注意它们的引导词以及限制条件。 1、在非限制性定语从句中 which 可以作主 语， as 则一般不用作主语; 2、在状语从句中用来表示“一……就”的习惯搭配有 hardly / scarely ...， no sooner … than ; 3、可以引导原因状语从句的符合连词有 in that，now that 。 seeing that，considering that …等; 4、在名词性从句中应该注意 whether 和 if 的区别。 Whether 引导的从句可以放在句首，而 if 则不行; if 引导的从句可以有否定的形式，而 whether 从句就不行; whether 和 or not 可以连起来用，但 if 和 0r not 就不能连用， or not 必须放在句末。 看一道 例题： 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 抛开前面的从句先不看，后面主句的意思是今天雇员越来越多地成为中产阶级，受过扎实的正规教育，担任需要智力和技能的专业工作或管理工作。从句的意思是 50 年前，被雇佣就意味着在工厂或农场里当劳力。显然前后句所表达的并非同一个概念，空格中应该填入表示让步的连词，引导从句。 when 在这里的用法比较特殊，它可以代替 although ，所以正确答案是 A 。又如： You describe the boy as stupid，when in fact he is very smart .你把那个男孩说得很笨，但是实际上他非常聪明。 二、时态 英语中最常见以及常考的时态是一般现在时、一般过去时、一般将来时、现在完成时、现在进行时等八种。这些时态我们几乎在每次使用英语的时候，无论是说话或者是写作，都会遇到，一般用法早已熟记于心了，复习的时候只要留心他们的一些特殊用法，这里以现在完成时和现在 ( 完成 ) 进行时为例。 现在完成时的一些特殊用法： l、在 this is(it is)the first time that …句型中，从句常用完成时态。如： It is the second time he has been out with her . 2、 have been t0 与 have gone to 的区别。前者侧重表示经历过，说话人可能已经不在那个地方，或者已经回来了。而后者表示已经去了那里，说话的时候可能还在那里，或者在去那里的路上。 3、用在时间或条件状语从句中，表示将来某个动作发生之前业已完成的动作，如： I ll go to see the film as soon as I have finished my homework .我一做完作业就去看电影。其中做完作业的动作在看电影动作之前完成。 4、 when 引起的疑问句中一般不用现在完成时，因为询问者关心的是事情发生的具体时间现在 ( 完成 ) 进行时除了表示正在进行的动作之外，还主要有以下的用法： l、与频度副词如 always，continually，constantly 。 forever 等状语连用，表示经常发生的，具有持续性动作的事情，或者表示不满，或者心中抱怨。如： She is always thinking 0f others .她总是替别人着想。 2、与 hope、 wonder、 want 等词连用，表示婉转的口气，例如： I m wondering if you could lend me some money . 3、另外还因该注意到，表示心理状态、情感、感觉、所有关系及特征等状态的动词一般不用进行时，如： smell，taste，sound，notice， hate，like，love，believe，understand，Want，seem，appear，contain，see ，hear，agree，belong 等。 看一道 相关的例题： The company _______a rise in salary for ages 。 but nothing has happened yet promised been promising promising D. promised 这个句子的意思是说公司长期以来一直答应增加工资，但依然毫无结果。句子中有时间状语 for ages 。它常与现在完成时连用，这种时态强调动作的持续性，表示现在以前的这一段时间里一直在做而且现在仍然在进行的一个动作。另外， but 以后的从句也表示了现在完成时，说明和现在有关。正确答案应该是 B ，可以和现在完成进行时连用的表示一段时间的状语还有 for a year，these few early morning，since yesterday，for about two hours 等。把它们与进行时用在一起表示动作正在和一直在延续进行。 三、不定式 动词不定式是非谓语动词的重要组成部分，在六级考试中非谓语动词部分是一个重点。常跟不定式的动词有 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 的单词之后，我们来看一看在什么情况下单词 to 可以被省略。 l、在一般助动词或者情态动词之后 to 可以被省略。 2、在动词 make，let， watch，see …之后作宾语的时候， 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? 为什么花这么多时问 ? 和 Why not go right now? 为什么 不 现在去呢 ? 以上就是英语四级帮助。
