2018考研英语语法：状语从句的省略
2018考研英语语法：状语从句的省略语法是考研英语当中除了词汇以外又一大让人头疼的板块，可真是“语法，想说爱你不容易”，但是语法的复习又是必不可少的，文都网校考研频道整理了考研英语语法之状语从句的省略，快来看看吧!
状语从句的省略是英语语言在使用过程中出现的一种较普遍的语法现象，一方面，它能使句子变得更简洁，但另一方面，它对你的理解能力提出了很高的要求，增加了理解的难度。我们知道状语从句的引导词可以帮助大家判断前后两句话的逻辑关系，一旦省略了引导词，那么弄清楚前后两句话的逻辑关系就比较难，这就需要大家掌握状语从句的省略原则，在此基础之上再进一步分析前后的逻辑关系，从而把里面的逻辑关系翻译出来。
当主句的主语与从句的主语一致时，可以省略从句的主语，连接词可以保留，从句中的谓语动词与主语是主动的关系就用动词的ing形式，如果是被动的关系就用ed形式。比如说2011年英语二翻译的一个句子：While producing large quantities of CO2, these computers emit a great deal of heat, so the centers need to be well
air-conditioned。这句话中while后面的句子省略了主语，因为从句中的主语和后面的主语一致都是these computers，并且动词produce与主语是主动的关系，所以变成分词形式producing。这句话翻译为：这些计算机在产生大量二氧化碳的同时，还释放了大量的热量，因此数据中心需要良好的空调设备。
当主句的主语与从句的主语不一致时，要保留从句的主语，连接词必须省略，从句中的谓语动词与主语是主动的关系就用动词的ing形式，如果是被动的关系就用ed形式。比如说1999年英语一阅读中的这句话：But, for a small group of students, professional training might be the right way to go since well developed skills, all
other factors being equal, can be difference between having a job or not. 这句话的状语是all other factors being equal，省略了连词because，因为主句的主语与从句的主语不一致，所以保留了all other factors。All other factors与后面的谓语动词之间是主动的关系，把后面的be动词变成分词形式就可以。翻译为：但是对少数学生而言，职业培训也许是可取之路，因为在其他因素相同的情况下，熟练的技能是能否得到工作的关键。
还有2007年英语二阅读理解中的一句话，Thanks to an accident of history, most Americans receive health insurance through their employer, the government picking up the bill for the poor and the elderly. the government与主句主语most Americans不一致，保留状语从句的主语，后面谓语动词用动词ing形式是由于pick与the government是主动的关系，翻译为：由于历史的偶然，大部分美国人通过他们的雇主来获得医疗保险，而政府则帮穷人和老人买单。
状语从句的省略是状语这部分内容的难点，当状语的连词省略了，很多同学不能判断出来状语与主句的逻辑关系，就会出现翻译的障碍，影响理解，这也是考研英语句子中的比较难的一种语法现象。

2018考研英语十二大基础语法体系之一致关系_毙考题
2018考研英语十二大基础语法体系之一致关系 语法基础贯穿英语的各个题型，基础复习阶段，词汇和语法都是基础和重点。小编带大家一起来梳梳理十二大基础语法体系，下面是一致关系语法知识点，大家注意学习和应用。十二大基础语法体系之一致关系 一致关系 英语的一致有三种:主谓一致，代词一致，肯定与否定一致 (一)主语与谓语的一致 英语语法要求，主语如果是单数，谓语动词也要用单数形式;主语若是复数，谓语动词也要用复数形式 例如: She likes to eat well.她好吃 We all like good food.我们都喜欢好饭菜。 Everybody was happy with the decision. 人人都对这个决定感到高兴。 I am a doctor.我是个医生。 (二)概念一致 1. And连接的两个或多个单数名词作主语时，谓语动词用复数形式 His opinion and mine are different他的观点和我的是不同的。 Bob and Peter are deadly rivals. Bob和peter是死对头。 What she says and what she does are totally different. 她说的和做的完全不同。 但是如果and连接的是指一个单一概念时，谓语动词用单数。 Bread and milk has been my breakfast for years. 牛奶面包多年来一直是我的早餐。 Her lawyer and old friend is going to marry her.她的律师和老朋友要娶她。 All this effort and sacrifice has come to nothing. 所有这些努力和牺牲都白费了。 由and连接的单数主语分别有many a，ever y，each，no修饰时，动词用单数。 如：During the holidays, every train and every plane was crowded.假期期间每列火车及每架飞机都非常拥挤。 No boy and no girl has the right to refuse education. 男孩和女孩都没有拒绝教育的权利。Man a man and man a woman was moved b this picture。许多男男女女都被这幅画感动。2.如果主语是一个抽象概念(如不定式、动名词、主语从句等)谓语动词用单数形式。如果主语是用and连接的两个或多个抽象概念，谓语动词用复数形式。 如：Swimming jogging and cycling are all goad farms of sports exercises.游泳、慢跑和骑自行车都是很好的运动形式。 To live to eat is not a very goad attitude toward life. 活着就是为了吃不是好的生活态度。 To live to eat and to eat to live are very different attitudes toward life. 以what，who，why，haw, whether等wh一词引起的从句做主语时，谓语动词通常用单数;由and连接的两个主句如果指两件事，动词用复数。

2019考研英语语法解析：副词_毙考题
2019考研英语语法解析：副词 学习语法和学习语言是相辅相成的，英语水平要提升，语法知识点必须要熟练掌握。基础复习阶段，对于遇到的相关语法一定要弄懂弄会。小编分解各个语法知识点，帮助大家一一攻克。下面是副词语法知识点解析： 2019考研英语语法解析：副词 副词可修饰动词、形容词、副词、介词短语及整个句子。 例句： disappointment. (1997年第3题) 分析：该句是简单句，其中副词much修饰介词短语。 译文：我父亲的弟弟安德鲁不会参加野餐，这令全家人非常失望。 一、副词的分类 1. 时间副词，如now, yesterday, today, ago, then, lately, soon, shortly, immediately, finally, recently, before, tomorrow。 例句: Americans 选自2004年Text 4) 分析：该句是简单句。 译文：现在美国人不重视智力。 2. 地点副词，如here, there, above, below, downstairs, upstairs, home, somewhere, everywhere, elsewhere, down, up, anywhere等。 例句：Here is an example, which I he because the audience all shared the same view of doctors. (选自2002年Text 1) 分析：该句是复合句，两个which引导的定语从句分别修饰an example和a story，前一个which引导的定语从句为非限制性定语从句，起补充说明作用。 译文：比如说，在一次护士大会上，我听到了一个能很好地发挥幽默效果的故事，因为所有的听众都对医生持有相同的看法。 3. 程度副词，如fairly, rather, very, almost, too, quite, enough, so, much。 例句: She had clearly no intention of doing any work, although she was very well paid.(1997年第34题) 分析：该句是复合句，although后面跟的是让步状语从句。 译文：虽然付给她的报酬丰厚，但她无意去工作。 4. 频率副词，如sometimes, often, usually, always, frequently, constantly, rarely, seldom, never, occasionally。 例句： according to the functions that need to be served. 分析：该句是简单句，其中意为内嵌式的。在方式状语中，that need to be served 为定语从句，修饰the functions。 译文：此外，根据需要满足的功能，设计者通常必须选择家具或设计内嵌式家具。 5.方式副词，表示动作发生或进行的方式，如quickly，fast，slowly，suddenly，carefully，well, properly, roughly, angrily, rudely。 例句：You would be shocked if the inside of your bedroom were suddenly changed to look like the inside of a restaurant. 分析：该句是复合句，if引导的从句表示与现在相反的虚拟语气。 译文：如果你的卧室内部突然变得和饭店内部一样，你可能会大吃一惊。 6.疑问副词，如when, where，how，why, who。 例句：So where are the headlines warning of gloom and doom this time? (选自2002年Text 3)
初中英语语法状语从句大全
初中英语语法状语从句大全 1.时间状语从句 引导连词有when，while，till，not…until，since， after ,before ,as soon as The bus won’t start until everybody gets on. 公共汽车直到每人都上车为止，才开动。 When he knocked at the door I was cooking. 当他敲门时，我正在煮饭。 Last night before he came back home, his wife had already cooked dinner and waited for 2 hours. 昨天晚上在他回到家之前，他的妻子已经做好晚饭足足等了他两小时之久。 After I went to church, I went shopping. 2. 地点状语从句 地点状语从句通常由where, wherever 引导。 Where there is a will, there is a way. 哪里有志向，哪里就有出路。有志者事竟成。 Where there is a life, there is a hope. 哪里有生命，哪里就有希望。留得青山在，不怕没柴烧。 Wherever you go, whatever you do, I will be right here waiting for you. 不管你去哪里，不管你做什么，我都会在此守侯你。
3.原因状语从句 引导连词有because，as, since。 He didn′t see the film because he had seen it. 他没有看那部电影，因为他已经看过了。 They couldn’t get on the train，for it was too crowed. 比较：because, since, as和for 1) because语势，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since。 I didn't go, because I was afraid. Since /As the weather is so bad, we have to delay our journey. 2) 由because引导的从句如果放在句末，且前面有逗号，则能 够用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。 He is absent today, because / for he is ill. He must be ill, for he is absent today.
2018考研英语语法长难句之并列结构(例句版)
2018考研英语语法长难句之并列结构 （例句版） 语法长难句，对于任何一个认真准备考研英语的考生而言，都不会是陌生的词。那么经常出现在考研英语中的长难句大概都有哪些结构呢?总的来说，考研英语中的语法长难句类型包含如下：隔离结构、并列结构、同位语从句、后置定语、状语从句、标语从句、插入语、比较结构、强调和倒装等。今天，就来带领大家来看一下那些在考研英语中出现的长难句结构---并列结构。 并列结构，顾名思义，并列结构就是将性质相同，内容相似，结构相似，无先后顺序，无因果关系的成分或者句子的并列的结构。因其成分为并列出现，故被称为并列结构。在英语句子中，经常出现“and，but，as well as，or，or else，both...and，neither...nor，either...or，not only...but(also)，as...as”等，将两个性质对等或是结构对等的部分连接成并列结构。无论是在做阅读理解还是翻译模块时，平行结构的作用还是比较大的：考生可以根据出现的平行结构来推断出与其对等的部分，进而可以通过对已知部分的理解，来推断出对等部分的含义，最终达到理解整个句子的意义。 例如：And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. 在个句子中，句子的主干为：one leading authority says that+宾语从句;而在这个宾语从句“these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better.”，我么可以看到not only...but(also)..结构，很明显，宾语从句中包含着一个并列结构;而并列的两部分为harnessed 和brought under conscious control;“to help us sleep and feel better”是状语成分。那么这个句子在进行翻译时，就要考虑到这个平行结构的处理：而一名顶级权威认为，这些极其强烈的大脑活动不仅可以被抑制，实际上还可以受到意识的控制，进而帮助我们睡得更香，是我们感觉更好。 同时，在2015年的考研英语题目中，有一道题目是词义考查题目：24.The word “moola”(Para. 4) most probably means . [A]skills [B]energy [C]earnings [D]nutrition 定位到文中第四段的句子，我们就可以很轻松的选出答案：“The bargain is very pure: Employee puts in hours of physical or mental labor and employee draws out life-sustaining moola.”。根据and前后的关系puts in hours of physical or mental labor和draws out life-sustaining moola，就可以推断出“几个小时的体力和脑力劳动的投入”就可以“获得维持生活的工资”。 通过长难句中的平行结构给各位考生展示了“对付”平行结构的方法，希望考生可以在之后的复习过程中，对于这类结构多加留意和用心，并能投入到长难句的复习当中。 其实看看凯程考研怎么样，最简单的一个办法，看看他们有没有成功的学生，最直观的办法是到凯程网站，上面有大量学员经验谈视频，这些都是凯程扎扎实实的辅导案例，其他机构网站几乎没有考上学生的视频，这就是凯程和其他机构的优势，凯程是扎实辅导、严格管理、规范教学取得如此优秀的成绩。 辨别凯程和其他机构谁靠谱的办法。 第一招：看经验谈视频，凯程网站有经验谈视频，其他机构没有。

2019考研英语语法小讲：复合句
2019考研英语语法小讲：复合句 复合句(Complex Sentence) 一个主句和一个以上的从句所构成的句子称为复合句，也称为主从复合句。复合句通常由关联词把主句和从句连接起来。 例句： Other models exist that are hybrids of these three, such as delayed open瞐ccess, where journals allow only subscribers to read a paper for the first six months before making it freely available to everyone who wishes to see it. (选自2008年Text 2) 分析：该句是复合句，其中主干结构是Other models exist;that引导的定语从句修饰models，而在从句中又套了一个由where引导的定语从句修饰open瞐ccess;在 where从句中，before 引导的时间状语从句中有一个who引导的定语从句修饰 everyone。 译文：其他存有的模式都是由以上三种模式相结合的产物。比如延缓式广开门路的模式，前6个月只允许付费的订阅者查阅相关论文，之后，才对大众免费开放。 例句： However, whether such a sense of fairness evolved independently in capuchins and humans, or whether it stems from the common ancestor that the species had 35 million years ago, is，as yet，an unanswered question. (选自2005年Text 1) 分析：该句是复合句，本句中由or连接两个并列主语从句，后接系表结构is an unanswered question;定语从句that the species had 35 million years ago修饰the common ancestor。
