大学英语四级考试语法：—定语从句

大学英语四级考试语法：—定语从句 很多同学在大学英语四级考试中会存在一些误区，认为语法不那么重要，其实英 语语法是学习英语的指南，对我们帮助很大。以下是小编给大家整理的大学英语四级 考试语法：—定语从句，希望可以帮到大家 1、mary is a beautiful girl. 名词的扩展靠限定，最基本的就是在名词的前面增加一个形容词这样的定语，上 面的句子就是表语girl的前面加了一个形容词。显然，如果只是mary is a girl这样的 句子会让人觉得非常枯燥，没有什么意义，所传递的信息量极其有限。所以，名词前 面加定语，可以使被限定的名词更加生动，更加形象而富有生命。如果要对名词给出 更多限定，挖掘更多内部信息，我们可以在名词前面加多个定语来限定，如mary is a beautiful chinese girl. 放在名词前面起到限定作用的定语有很多种形式，形容词，名词，动词现在分词，动词过去分词等。虽然形式多样，但是这类定语还是比较好理解，只要顺着句子的顺序，就基本可以明白是怎么回事。 2、the computer that i bought yesterday works well. 有时候，我们需要对名词给出很多的说明，用大量的信息来限定名词。这时，如 果还是把长长的限定成分放在名词前面，就会头重脚轻，所以英语中会用跟在名词后 面的定语从句来限定前面的名词。根据定语的功能还可以分为限制性定语从句和非限 制性定语从句。两者的区别在于前者与被限定名词之间没有逗号，而后者则有逗号隔开;前者起到限定作用，不可或缺，后者起到补充作用，舍去后对剩余部分影响不大。 本句子通过“that i bought yesterday”这个that引导的定语从句，使得主语the computer得到限定而明确，是我昨天买的计算机而不是别的。如果明白了这个名词可 以通过后面加定语从句来扩展，我们的句子马上可以变得复杂起来，请看下例：another popular spectator sport, which is known as the sport of kings, is horse-racing, which is controlled by the jockey club. 译文：另一种以特大型运动著称的流行观赏运动是赛马，这种比赛由赛马总会控制。

He was asked a number of questions at the press conference.

大学英语四级考试技巧重点总结

大学英语四级考试技巧重点总结 大学英语四级考试,是每个大学生都要过的一项英语水平考试。 那么如何顺利复习考过英语四级,有哪些英语四级考试技巧和经验总结呢? 接下来就给大家详细讲讲这些问题吧,希望对大家复习英语四级有所帮助。 一、英语四级考试听力技巧 备考听力,要先复习好听力。 在平时的复习中,可以充分利用琐碎时间练习。 然后只要掌握一定的英语四级考试技巧,听力就能拿到高分。 英语四级考试听力技巧可概括为以下3点: 第一就是听前预测。 大家可以在听力开始播放之前就快速浏览一遍题目,划出题干和选项中的关键词,这样可以大致推测出这篇文章的主题是什么。 第二就是记笔记。 大家在听的时候要及时记下和题目有关的关键信息,这样做题时就能够快速定位正确选项,而不用每道题都回想半天。 第三就是要特别注意试题的排列次序。 因为四级听力题常常将小题按录音材料的内容排列顺序。 所以如果没有时间预先阅读选项或时间不宽裕,大家也可以边听录音边依次浏览选项,同时进行思考、答题。 二、英语四级考试翻译技巧 英语四级考试翻译题型与听力,阅读,写作相比不一样。 因为,其它几部分只需要提升英语水平即可。 而翻译,不仅需要扎实的英语基础,更需要深厚的中文功底。 英语基础知识的夯实,你可以在真题中学习。 真题资料可以帮你逐句精解单词和语法知识,词汇注释和语法知识详细到可以不用查阅任何资料。 能为你的复习节省大量的时间,大大提高你的复习效率。 翻译做题技巧: 1.翻译时有必要增加词语来使英文的表达更加顺畅。

2.为了有更强的节奏感和押韵,汉语中也经常会出现排比句。 在翻译这些句子时,为了符合英文表达的逻辑,就要有所删减或省略。 3.注意词类变形和词性转换,尤其是名词、动词、形容词之间的转换。 4.要注意语态之间的转换。汉语中主动语态出现频率较高,英语中被动语态的使用率较高。 5.在遇到较长的句子或较复杂的句子时,可以考虑分译,以使译文简洁,通俗易懂。 三、英语四级考试写作技巧 英语四级写作复习技巧之前,建议大家多学习四级范文。 写作考试技巧: 1.卷面整洁,不要做涂改。 2.少用模板、少说空话,多些现场发挥,这点要求你要注意平时积累。 建议大家背点开头、结尾的万能句型,积累一些好的写作语料,四级作文就成了。相关文章： 1.英语知识 2.30%的英文 3.英语资料下载 4.英语最实用口语100句 5.各等级的英语水平是什么

大学英语四级语法考点透析

第一章动词的时与体(Tense & Aspect) 时（tense）是个语法范畴，它是表示时间区别的动词形式。英语动词只有“现在时”和“过去时”，而没有“将来时”（在英语中，表示“将来”手段多种多样，但没有一种独特的、能与“现在时”和“过去时”平起平坐的专一表示“将来”的动词形式----“将来时”）。 体（aspect）也是一个语法范畴，它表示动作或过程在一定时间内处于何种状态的动词形式。英语有进行体(progressive aspect)和完成体(perfective aspect)。进行体是由助动词be的一定形式加主动词的-ing 分词构成；完成体由助动词have的一定形式加主动词的-ed分词构成。 现在时和过去时既可以单独使用，也可以和进行体或完成体结合使用，也可以同时与完成体和进行体结合使用。这样，英语的限定动词词组便有8种时、体形式。它们分别是：一般现在时(simple present)、一般过去时(simple past)、现在进行体(present progressive)、过去进行体(past progressive)、现在完成体(present perfective)、过去完成体(past perfective)、现在完成进行体(present perfective progressive)、过去完成进行体(past perfective progressive)。在这一章中，我们单独挑出完成体来加以详述。 1．1 必须使用完成体的结构 1）It (This, This evening, yesterday...) is (was, will be) first (second, third...) time (day, month…)…结构中的分句，要求用完成体。 Is this the first time you've been to Beijing? This was the first time he had been to Beijing. This is the eighth month that I have been out of work.. This was the eighth month that I had been out of work. This is the second time that the goods produced by our factory have been shown in the International Exhibition. This was the second time that the goods produced by our factory had been shown in the International Exhibition. 2）在no sooner…than, hardly/barely/scarcely…when,等的句型中，主句要用过去完成体。 He had no sooner seen me than he left the room. No sooner had he seen me than he left the room. The helicopter had hardly landed when the waiting crowd ran toward it. Scarcely had I seen the lightning when I heard a clap of thunder. 3）将来完成体用来表示在将来某一时间以前已经完成或一直持续的动作。经常与before+将来时间或by+将来时间连用，也可与before或by the time引导的现在时的分句连用。 I will have finished all the work by the time you are back this evening. I am sure he will have left Paris by this time tomorrow. I hope we will have got all the information before you come tomorrow. By the time you get to New York, I _______for London. （2002年1月） A) would be leaving B) am leaving C) have already left D) shall have left 本题时间状语为by+将来时间，考察将来完成体用法，应选择D)。 By the time he arrives in Beijing, we ________here for two days.（2001年6月） A) have been staying B) have stayed C) shall stay D) will have stayed 将来完成体用来可以表示在将来某一时间以前一直持续的动作，本句话的意思是：我们将在这里呆两天，因此谓语动词用将来完成体，答案为D)。 1．2 现在完成体与现在完成进行体 现在完成进行体兼有现在完成体和现在进行体二者基本特点。由于它有现在完成体的特点，所以它

I wish (that可省略,下同)I knew the answer to the question.(wish, 动词过去式knew)我希望知道这个答案。(事实上是不知道) 2. I wish it were spring in my hometown all the year around.(wish, were)但愿我的家乡四季如春。(事实上不可能) 3. I wish I were a bird.(wish, were)但愿我是只小鸟。(事实上不可能) 4. When she was at the party,she wished she were at home.(wished,过去虚拟动词were)(事实上并不在家) 5. Now that he is in China, he wishes he understood Chinese.(wishes,过去虚拟动词understood)

现在他在中国，他希望能懂得中文。(事实上并不懂) 6. When we begin the trip, they will wish they were with us.(will wish,过去虚拟动词were)(事实上并不和我们在一起) 二)、对过去情况的虚拟(和过去的事实相反)： 用wish表示对过去事情的遗憾。其句子结构为：宾语从句的谓语用过去完成时，或would, could, might+现在完成时。例： 1.

大学英语四级常考语法总结

大学英语四级常考语法总结 一、虚拟语气。应着重复习能引起虚拟语气的某些介词、介词短语和连词(如lest, in case, otherwise等);一部分表示建议、主张、命令等概念的词语，由于本身隐含说话人的主观愿望，其后的主语从句、宾语从句、同位语从句往往采用“should+动词原形”;虚拟倒装句;在would rather, wish, as if, it’s time that等句型中使用适当形式表达主观愿望;混合虚拟句。 二、独立主格题。一般说来，在句子中没有连接词的情况下，逗号是无力连接两个句子的，其中一个分句要么是非谓语形式，要么是独立主格结构。两种结构都做状语，不同的是独立主格结构有自己的逻辑主语。 三、时态。英语中共有16个时态。四级考试中出现最多的是将来完成时、现在完成时、过去完成时和完成进行时。 四、名词性从句。形容词性的定语从句是考核的重点，用什么引导词，引导词前面的介词形式，引导词在从句中做什么成分，从句的语序等均有可能成为考点。此外，主语从句、同位语从句、宾语从句也应适当复习。 五、主谓一致。这类考题灵活性大，需要根据实际情况判断谓语动词的单复数形式。一部分具有生命意义的集合名词做主语时谓语动词多采用复数形式，如people, poultry, militia等;用and连接的成分表单一概念时谓语动词用单数;就近原则：主语中含有某些连词(如as well as, besides, in addition to等)时，谓语动词的数同第一个主语保持一致。

六、倒装结构。分为全部倒装和部分倒装。那些否定词(组)、介词短语能引起倒装句，部分倒装和全部倒装有和区别，as在倒装结构中的用法及意义等等，都是考生应当重视的地方。 七、非谓语动词。①根据非谓语动词同其所修饰的名词或逻辑主语的一致关系，确定使用主动语态或被动语态，然后考虑采用现在分词、现在分词被动式或过去分词;②非谓语动词同主句谓语动词动作发生的先后关系。动作正在进行的用现在分词进行式，同时发生或不分先后发生的用现在现在分词一般式或过去分词;在主句谓语动词之前发生的用现在分词完成式、不定式完成式;发生在主句谓语动词之后的多用不定式一般式;③表状态多用分词，表目的多用不定式。
