英语五大基本句型讲解

英语五种基本句型详解 句子是由主语、谓语动词、表语、宾语、宾语补足语等组成的。英语句子有长有短，有简有繁，似乎千变万化，难以捉摸，但其实只有五种基本句型。所有英语句子都可以看成是这五种基本句型的扩大、组合、省略或倒装。因此掌握这五大句型，是掌握其他各种英语句子结构的基础。 英语句子依其组合方式可分为以下五种基本句型，句子成分的表示法为: S: Subject （主语）， V：Verb （动词）， O: Object （宾语）, 10 : In direct Object 间接宾语）, DO: Direct Object 直接宾语）， P：Predicative （表语）， OC: Object Complement （宾语补足语）。 五种基本句型见下表 种类句型例句 第1种S+V （主语+不及物动词） We work.（不及物） 第2种S+V+O（主语+及物动词+宾语） He plays （及物）the pia no 第3种S+V+P （主语+系动词+表语）We are （系动词）stude nts. 第4种S+V+IO+DO（主语+及物动词+间接宾语She gave （及物） me

考研英语翻译技巧——it形式主语句型

考研英语翻译技巧——it形式主语句型 考研英语中，形式主语通常是指it作形式主语的情况。在翻译时，我们一般都将其处理为固定词组，置于句首。形式主语分为以下两种： ①It is+v-ed+that It is said that...据说……；It is reported that...据报道……；It is estimated that...据估计……；It is suggested that...据建议……；It must be admitted that…必须承认……；It should be realized that...应该意识到……；It can be found that...可以发现……；It is agreed that...大家一致认为……；It cannot be denied that…不能否认……；It may be said without f e a r o f e x a g g e r a t i o n that…毫不夸张的说…… ②It is +adj.+that It is clear/certain/natural/necessary that...是很明显/很肯定的/很自然/很有必要的。例如：It is strange that she should have failed to see her own shortcomings.奇怪的是，她并没有看到自己的缺点。 考研英语中，it作形式主语的情况常出现在主语从句中，且以It 作形式主语置于句首，而that引导的真正的主语从句置于句末。主要有两种情况：it形式主语+主语从句；it形式主语+不定式。下面我们将通过真题例句，介绍这两种情况下句子的翻译技巧。（本文由太阳城考研1号编者原创）

英语中的五种基本句型

五种基本句型 句子由主语和谓语两大部分组成。主语结构比较单一，谓语结构则不然，不同类别的谓语动词导致不同的谓语结构，从而形成了不同的句型( Sentence Pattern )。换句话说，不同的句型是由不同类别的谓语动词所决定的，因此，句型又被称为动词句型 ( Verb Pattern )。语法家们对句型的分类不尽相同，一般认为，现代英语的基本句型主要有五种： 1. “主----系-----表” (SLP)句型： 在这种句型中，谓语动词是以be为主的连系动词(Linking Verb )，后面跟主语补语(Subject Compleme nt),如： These oranges have kept fresh. 这些桔子一直很新鲜。 Mary is a student / here /in the room. 玛丽是个学生/ 在这儿/ 在房间里。 有的语法家把be后面的副词(短语)或介词短语视为状语，从而形成了“主----动----- 状” (SVA这一在五种基本句型之外的句型(见上面最后一个例句)。 2. “主----动” (SV句型： 在这种句型中,谓语动词为不及物动词( Intransitive Verb ),谓语部分通常只包括限定 动词,即使有状语,也属任意性状语,即：去掉后并不影响句子结构和意义的完整,如： This bread won 't keep (for a long time). 这种面包不好(长期)存放。 Tom has left. 前面说过, 有些句子中的状语是不可缺少的,这种状语被称为必具性状语,从而构成“主 ----动----状” (SVA)句型，但这仅限于少数几个动词的某些用法，因而不是一种主要句型，如： They are staying in a hotel. 他们暂住在一家旅馆里。 3. “主----动----- 宾” (SVO 句型： 在这种句型中,谓语动词为只带一个宾语的及物动词,这种动词被称为单宾语及物动词 ( Monotransitive Verb ),如： He kept the money. 他保存着这些钱。 The train leaves London at nine. 这列火车九点钟驶离伦敦。

“It”作形式主语和形式宾语用法详解

新希望英语语法精讲------“It”作形式主语和形式宾语 “It”作形式主语和形式宾语的用法详解 It作形式主语和形式宾语用法，是英语学习的主要语法项目之一。无论是单项选择，还是完行填空，it 用法始终是反复考查的重、热点之一。现将it在特殊句型中作形式主语和形式宾语用法，进行如下归纳分析，以供学习参考。 一、It 用作形式主语当不定式（短语）、动名词（短语）或从句在某个句子中作主语时，为保持句子结构前后平衡，避免头重脚轻，因此常用it作形式主语置于句首，而将真正的主语放在句尾。此时it只起先行引导作用，本身无词义。 e.g. It is wrong to tell a lie. (说谎是错误的。) 〔It为to tell a lie的形式主语〕 It is no use arguing about it. (争吵是没用的。) 〔It为arguing about it的形式主语〕 It is uncertain who will come. (谁要来还不确定。) 〔It为who will come的形式主语〕 It 作形式主语的常见句型： ①It + be + 形容词+ to do sth. / doing / that …. e.g. It is very important to learn a foreign language. (学一门外语非常重要。) It is useless crying over the spilt milk. (覆水难收。) It was really surprising that she married a man like that.(她嫁给那样的男士真让人惊讶。) ②It + be +名词词组+ doing / that …. e.g. It is no good telling lies. (撒谎没好处。) It is a pity that you didn’t go to see the film yesterday. (你昨天没看成那部电影真遗憾。) It is a truth that there would be no new China without the Communist Party. (没有共产党就没有新中国，这是毋庸质疑的。) ③It + be + 过去分词+ that …. 该句型常见动词有：say, hope, think, suppose, expect, report, know, believe, decide, etc. e.g. It is said that they have invented a new type of computer. (据说他们发明了一种新型电脑。) It is believed that China will become one of the strongest countries in the world. (大家都相信中国将会步入世界强国之列。) It was reported that more than 170 thousand people died in the 2004 tsunami. (据报道，至少有十七万人在2004年那场海啸中丧生。) ④It + seems / appears / happens等不及物动词+ that …. e.g. It seems that he enjoys pop songs very much.(似乎他非常喜欢流行歌曲。) It appears that Tom might change his mind. (看来汤姆可能会改变主意。) ⑤若句子是疑问形式，就只能用it作形式主语。 e.g. Does it matter much that they won’t come tomorrow? (他们明天不来很重要吗？) Is it true that he will go abroad next week? (他下周出国是真的吗？) ⑥It + takes + (sb.) + some time + to do sth. 这是一个表示“（某人）花多少时间干某事”的句型，其中it是形式主语，代替后面的不定式（to do sth.），句型中的sb.也可以省略。 e.g. It took me some time to read the reading materials.(我花了一些时间才读完那段阅读材料。)It took him fourteen hours to go to New Zealand from Shanghai by plane.(从上海乘飞机去新西兰花了他14小时。) How long does it take you to go to Beijing from Qingdao by train? (从青岛坐火车到北京一般要花多久时间？) I am not sure, but I think it takes at least nine hours to get there. (我不能肯定，但估计至少要九个钟头才能到那儿。) 二、It 用作形式宾语 当不定式（短语）、动名词（短语）或从句在某个句子中作宾语时，为保持句子结构平衡，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾。此时it仍只起先行引导作用，本身无词义。下列四种情况须用it 作形式宾语：
