句子的英译 主语和谓语的确定 翻译理论方法

翻译之虚拟语气

虚拟语气 第一种: 由“ if ”引导的虚拟句子 (1). 与现在的事实相反 [If --- + 过去式（be一般用were）---, --- + would do---] If I were you , I would marry him. 如果我是你,就会嫁给他。 (2). 与过去的事实相反 [If --- + had +过去分词---, --- +would have done---] If you had worked hard , you would have passed the exam. 如果你用功学习,就会通过考试了。(3). 与将来的事实可能相反 [If ---+ should +动原/wereto+动原/过去式---, ---+ would do---] If it should rain tomorrow , what would you do ? 如果明天下雨,你怎么办? 【真题】Linda __________________________________(不可能收到我的电子邮件)；otherwise, she would have replied.（2011,12） Couldn’t have received my email 【真题】You would not have failed if you _______________________________(按照我的指令去做).（2009,12） You had followed my orders. 解析：考点是虚拟语气。 【真题】If she had returned an hour earlier , Mary______________________________________ (就不会被大雨淋湿了). wouldn’t have been caught in the heavy rain . 解析：考点是虚拟语气、词汇。 【真题】If the reaction were to take place,____________________released.(巨大的能量就会被释放出来) Tremendous amounts of energy would 第二种: 用在表示要求、建议、命令等的名词从句中 从句谓语形式为 “---(should ) + do sth”(在美语中should常省去) 。 类似用法的动词有 insist (坚持) , suggest (建议) , order(命令) , propose (建议) , demand (要求) , command (命令) , advise (建议) , desire (要求、请求) , request (请求) , require (需要、要求) , ask (要求) , prefer (宁愿), recommend(推荐) , arrange ( 安排) , advocate ( 拥护、提倡) ,maintain(坚决主张)等后面的宾语从句中。 【CET-4:2006.6】The professor required that __________________(我们交研究报告)。 参考答案：we hand in our research report(s) 【真题】They requested that_______________(我借的书还回图书馆)by next Friday.【2010，12】books I borrowed （should）be returned to the library / I （should）return the book I borrowed to the library 解析：①request的用法。request v. 要求；当request表示“要求”时，引导的宾语从句要使用虚拟语气，即（should）+ 动词原形。②定语从句。“我借的书”，the book （that）I borrowed；③单词的拼写。归还return，借borrow，图书馆library ④本题提供了两个版本的答案，但在表示“规定，规则”时，被动语态更为常用。 第三种: 用在“It + be + important (,necessary , natural , essential , strange , absurd , amazing , annoying , desirable, surprising , vital , advisable , anxious , compulsory , crucial , imperative , eager , fitting , possible , impossible , improper , obligatory , probable , preferable , strange , urgent 等, 以及insisted , suggested , ordered , requested , arranged , recommended 等) + that ---（should）do sth”结构中的that 引导的主语从句中。 第四种：混合时间虚拟语气（主要是抓住时间状语） (对过去事实虚拟+对现在事实虚拟) If I had studied English at school, I could read the English novel now.

主语与谓语动词的一致

主语与谓语动词的一致 江苏沛县湖西中学鹿俊先 221611 英语谓语动词的形式必须随其主语的人称及数的不同而变化，这就叫作主语与谓语动词的一致，简称主谓一致。 在现代英语中除动词be有不同的人称形式(am, is, are, was, were)以及动词have有特殊的单数第三人称现在式形式(has)外，其余的动词只有单数第三人称现在式形式加-s / -es，其他形式则无区别。因此对于学习者而言，主谓一致问题主要是注意单数第三人称现在式动词形式加-s / -es的问题。处理主谓一致问题可依照不同的原则，即从不同的角度着眼。以下对这些原则及容易产生困惑之处加以分析、归纳。 1．语法一致，即主语为单数，就使用单数形式的动词，主语为复数，就使用复数形式的动词。 1．1．单数及复数名词的辨别。 某些名词单数词尾，却用作复数，如：people (人们), police, cattle, poultry（家禽）等。 People have the right to defend themselves. The police are investigating the murder of a six-year-old girl. The poultry have been fed. 某些名词复数词尾，却常用作单数，如：news, mathematics / maths, physics, politics等。

Mathematics / Maths（数学学科）is the science of pure quantity. (Her mathematics / maths（数学能力）are / is rather shaky.) The news is favourable this morning. 某些名词单数、复数形式相同，都是单数词尾，如：fish, sheep, deer, craft, Chinese, Swiss等。 In summer the red dear has a reddishbrown coat. A baby deer is able to stand up as soon as it is born. Baby deer are able to stand up as soon as they are born. 某些名词单数、复数形式相同，都是复数词尾，如：means (=way), works (=factory), crossroads, series, species, barracks, headquarters 等。 All means have been tried. Every means has been tried. 1．2．避免主语的同位语及其它修饰语语义上的干扰。 容易产生干扰的同位语：each, one of…, like …, such as…, including…, especially…, particularly…, for example,…等。 Some rubbish, such as / like food and paper, rots away over a period of time. Practical lessons, such as / like woodwork, are not considered to be as important as maths. We each have a different point of view. (each作同位语)

虚拟语气(含答案)

实验中学2014届高三英语语法专项复习------虚拟语气 虚拟语气的概念---虚拟语气是动词的一种特殊形式，用来表达说话人的愿望，意图，建议，惊奇，设想等未能实现的情况，以及在说话人看来实现可能性很小的情况。 虚拟语气的特点： １．虚拟语气表达的是与客观现实相反的观念。 ２．虚拟语气常由一个表示条件的从句和一个主句构成。 ３．由于虚拟语气中条件从句中的条件是与客观事实相反，因此其主句的结论也只能是想象的，非真实的。 ４．虚拟语气的特点决定了它句中动词形式的使用与真实句中的动词形式的是不同的。含if条件句的虚拟语气按时间的不同，分成以下三种形式：1）与现在事实相反的虚拟语气。 2）与过去事实相反的虚拟语气 3）与将来事实相反的虚拟语气 一．在不同时间下，含if条件句的虚拟语气的3种形式： 与现在事实相反 were might if+主语+ 过去式动词would ，主语+ could + V should 与过去事实相反 might would + have + 过去分词If +主语+had +过去分词, 主语+ could Should 与将来事实相反 were might if + 主语+ were to +v 主语+ would + V should + v. could 注：１.虚拟语气中助动词be的过去时(无论句子的主语是第几人称，是单数还是复数)一律用were，不用was。 ２.含if条件句的虚拟语气句子中，如果“if”从句中含有“were, had ”或“should ”时，则可省略连词“if ”，而把“were, had ”或“should”移至主语之前，构成倒装句。 1.与现在事实相反 １）If I had a car, I should be very happy. =Had I a car, I should be very happy.(将had提到句首，再将if省略，构成倒装句)

当主句的主语和从句的主语一致时且谓语动词为be

当主句的主语和从句的主语一致时且谓语动词为be，常省略从句的主语和be 动词. 省略的条件: (1)从句中被省略的主语必须与主句的主语一致,或者是it；(2)谓语动词必须含有be；(3)从句必须与主语和be动词一起省去，不可只省略主语而保留整个谓语，也不可只保留主语而省略谓语。 1. 由when/while/as/once/whenever/as soon as引导的时间状语从句 例：Please come here as soon as（it is）possible. While （I was——walking in the rain, I heard my name called. 我在雨中漫步时，听到有人叫我的名字。 由if/unless引导的条件状语从句例：She won’t come to party unless（she is）invited.由though/although/even if/even though引导的让步状语从句 例：He is very good at painting, though（he is）very young. T hough（he was）exhausted, he stayed up late. 尽管疲惫不堪，他仍很晚才睡。由because引导的原因状语从句 例：He was praised because （he was）brave. 5. 由wherever/where引导的地点状语从句 例：Fill in the blanks with articles where（it is）necessary. 从句和主句中相同或大体相同部分都可以省略 例：The sooner, the better. 越早越好。 She is as tall as I. 她和我一样高。 由as if/as though/as 引导的方式状语从句 例：The boy looked as if（he was）afraid of nothing. I wonder why he didn’t do as（he was）told to. 比较状语从句省略相同的部分： 例：She likes reading better than (she likes) going to parties. He has lived here longer than I (has lived). In winter it is colder in Beijing than（it is）in Guangzhou.
