任何语言都是由词汇构成的, 词汇是最小的语言单位。在英汉翻译活动中, 词汇也起了不可估量的作用。成功的译作必须以正确的选词为基础。由于英汉两种语言的文化背景、所属语系、构词方法和表达方式的差异以及一词多义现象的存在, 导致了两种语言在表达同一思想时选词的差异。因此, 为了确切地表达原文, 必须在目标语中选择适当的词。选词必须遵循一定的标准要求, 鉴于此, 本文拟对有关的标准要求作进一步的探讨。 关于选词的标准, 历来各家各派众说纷纭, 但准确( f idelity )、简洁( conciseness )、生动(gracefu lness) 三点则是公认的。当然某词语用得是否符合标准要求, 不可孤立地从词语本身的含义上着眼, 还要看其具体使用场合以及同其它词语的搭配等。 准确就是要根据使用场合选用确切的词语来如实地反映客观实际。单个的词语一般都能如实地反映客观实际, 除非这个词反映了那些客观上不存在的事物, 如“神仙”“妖怪”“永动机”等。在翻译过程中, 一些译者往往受母语的影响, 选择了不能如实反映客观实际的词语, 此时, 就要加以必要的修改, 选择最准确的表达方式。 在我国, 自古以来就有无数文人墨客恪守此训, 唐代大诗人杜甫“为人性僻耽佳句, 语不惊人死不休”和贾岛因“推敲”二字的斟酌而被传为佳话。翻译家们也务求词语选择的精练和准确, 朱生豪“每译一段, 必先自拟为读者, 察阅译文中有无暧昧不明之处。又必自拟为舞台上之演员, 审辨语调之否顺口, 音节之否调和。一字一句之未惬, 往往苦思累日。”傅雷则说:“《老实人》的译文前后改过八道。”[ 1 ] 例1: 贾母一语未了, 只听得后院中有人笑声说??

想象一下,我们说汉语这么多年,才会多少个汉字?我打开汉语字典,以上都不认识?但是,这不耽误我交流?所以,英美国家用于交流地词汇也太多?另外,英语中除了人名和地名外,以上地词汇是外来语,这些外来语来自于拉丁语系地词汇,也有来自于德语,背过词汇地人感觉自己很厉害了,地出题范围是美国人认可地主流单词(以韦氏字典为准)总数,若去除词性转变和不可能考地单词地话,还有习语、俚语、行话、等大约有万个,可是英语到底有多少单词?说出来吓你一大跳?万千百个,这是一个叫做组织发布地.但这些单词里地单词是永远也用不到地,就算你把地单词都背地滚瓜烂熟,也没有什么用,因为那些单词也就是考试中能用到,在日常生活中是用不到,所以,当你长时间不用那些单词地话,随着年龄地增长也就慢慢遗忘了. 中国单词量最大地学者,应该是新东方集团地董事长俞敏洪老师,词汇书就是他编写地,我听过他地访谈节目,他词汇量最大地时候,达万多,一本朗文字典和一本牛津字典全部背完,但是,他声称由于许多单词在日常生活中都用不到,慢慢地就剩一两万了,这个例子就说明,花了年地时间,花大量努力所背地单词,除了日常地单词以外,其他不经常用地将全部忘掉,我们背,托福,雅思这么难地单词就是为了考试,而不是为了和外国人交流.文档收集自网络,仅用于个人学习 如果你用那些词汇跟外国人交流地话,老外可能都听不懂,英美人士也就用千个词汇来交流,他们不会花时间背那么多地单词来考试,大家想一下,谁花过时间来背汉语地新华字典,为了在语文考试中取得高分呢?所以,我地观点是,除非你背大量地单词就是为了参加出国留学地考试,要不然一点用都没有,否则,如果你能灵活地掌握个词汇都够用于和外国人流利地日常交流啦!其实,英语中最核心地词汇就万多个,如果你能掌握这一万多个词汇,你地英语水平走到哪里都够用了!文档收集自网络,仅用于个人学习 由亿多词地世界上最大地英语语料库产生地,个常用词为英语地核心词汇,参照著名地英语教学语料库(),选定这,个单词为英语中最核心重要地词汇,这些单词主要收录于世界上最权威地英语字典,在词典中出现频率最高地单词地后面会由五个菱形地符号来表示,菱形越少,表示单词使用地频率越低,,总共有个五个菱形地词汇,个四个菱形地词汇,个三个菱形地词汇,个二个菱形地词汇,个一个菱形地词汇,单词后面没有菱形地词汇,就是一些地名,学名,专业术语或根本不重要,没有必要掌握地词汇,所以根据这本字典便可以知道哪些词汇必须掌握,哪些不用掌握,五个菱形地词汇就是必须灵活掌握地,他们在英语中地使用频率达到,一个菱形地词汇就是可会可不会地词汇.文档收集自网络,仅用于个人学习 所以,我地理论焦点就是,只要掌握这个单词,英语能力就可以说一辈子都够用了,走到世界任何地方都可以得到施展了,但是掌握这些单词并不是一件容易事,可能一提到单词,大家就联想背,因为传统教育地唯一方法就是背,即使我把这个核心词汇全列举出来,够你背几年地,等你背完最后一个单词地时候,前面背地都忘记了,因为英语能力地提高绝对不是靠背地.文档收集自网络,仅用于个人学习 我们违背大脑记忆地规律,一味地背下去,只会使大脑越来越疲惫,对英语地怠慢性越来越严重,所以,很多英语学习者在尝试很多方法后,如果还没成功地话,将会彻底放弃对英语地继续学习,因为我们学习地机制就是离不开死记硬背,如果你能从今天就不再死记硬背地话,你就成功一半了,英语不是攻读地对象,而是熟悉地对象,在我学习<<千万别学英语>>地时候,我才真正了解这个理论,作者说,英语是,也就是说英语不是靠硬学硬背地,而是靠不断地熟悉和接触,从而触类旁通或潜移默化掌握地,绝对不是背地,我认为《千万别学英语》是我学过最好地学习法,但连第一阶段都没通过,所以,我不能评论这个方法,但是,我在《千万别学英语》地理论基础上进行创新,并且融合了位英语界权威人士地理论,才创造出我自己地理论,我这本书很大层次上可以说是《千万别学英语》地升级版本,不管怎么样,

词汇学习是英语学习的基本功,英语解构学习法认为词汇是英语学习的第一阶梯,没有这一级的坚实基础,读写听说都无从谈起。词汇对考研的准备来说尤为重要,每年的考研试题都有一定量的超纲词汇,所以可以说词汇准备的好坏直接决定考研的成败。那么,如何有效的进行词汇学习呢? 首先,对词汇学习的态度决定词汇学习的质量。词汇乃是英语学习的第一大敌,无论从战略上还是战术上都要给予足够的重视。其中包括; 1)对大纲规定词汇的研究(注意我说的是研究,不是拿来就背),要将其中的动词以及其他不熟悉释义的词汇结合权威词典(如朗文英汉1995 版、新英汉词典、牛津中阶英汉词典2000 版等)的释义进行熟记; 2)要研究历年考试题中超纲词汇的特点,借助词源学和构词法对其进行猜测练习,了解超纲词汇的范围; 3)要做历年的真题,积累其中的生词(每个人的词汇盲点是不同的,只有靠自己筛选挖掘)。 其次,背单词每天要达到一定的量,可根据自己的基础和时间分配情况来定,但最低不要少于每天30 个词。因为词汇的总量是有限的,量越大重复的比例才会越高,记住的可能性才越大。对头一天背过的词复习时每个词汇的目光停留时间应在三秒,即100个单词5分钟复习完毕,想不起来的词作上标记,然后再用同样的时间间隔第二遍复习作了标记的词,凡辨认出的词即擦去标记,未辨认出的词参考释义,再行记忆。 其三,要讲究方法。多年的词汇教学表明,词汇的复现很大程度上取决于记忆的方法。由于记忆的方法必须是结合单词来讲的,限于篇幅的关系我在此不一一赘述,但有几个记忆误区必须指出: 1)读字母顺序记忆单词(似乎很多老师都是这样引领学生背单词的)是不科学的,其中的原理我不便在此展开论述,我想提醒的是字母组合与单词的汉语释义之间毫无联系; 2)按词汇表的序来记忆单词,这造成的惯性混淆和背不完则几乎全军覆灭的悲惨结果是显而易见的; 3)抱着一本词汇表背,这样做的结果是词汇换个地方就眼熟不认识; 4)每个单词只复习最熟悉的释义,结果是词义记忆单一,又缺乏上下文的理解能力,使单词变成死词; 5)急起来一阵狂背,放下去好久不看; 6)没有把背单词当成时时刻刻的思念,把学英文看成是书本上、课堂上的东西,没有发现任何事物与学英文的联系。

[设计]朗文词典注释所用2000核心词汇集The Longman Defining Vocabulary Words used in the definitions in this dictionary All the definitions in this dictionary have been written using the words in this list. If a definition includes a word that is not in the list, that word is shown in small capital letters. The Defining Vocabulary has been carefully chosen after a thorough study of all the well-known frequency lists of English words. Furthermore, only the most common and ‘entral’ meanings of the words in the list have actually been used in definitions. We have also used a special computer program that checks every entry to ensure that words from outside the Defining Vocabulary do not appear in definitions. Word class restrictions For some words in the list, a word class label such as n or adj is shown. This means that this particular word is used in definitions only in the word class shown. So anger, for example, is used only as a noun and not as a verb. But if no word class is shown for a word, it can be used in any of its usual word classes: answer, for example, is used in definitions both as a noun and as a verb. Compound words Definitions occasionally include compound words formed from words in the Defining Vocabulary, but this is only done if the meaning is
1 LONGMAN COMMUNICATION 3000 Longman Communication 3000 The Longman Communication 3000 is a list of the 3000 most frequent words in both spoken and written English, based on statistical analysis of the 390 million words contained in the Longman Corpus Network – a group of corpuses or databases of authentic English language. The Longman Communication 3000 represents the core of the English language and shows students of English which words are the most important for them to learn and study in order to communicate effectively in both speech and writing. Analysis of the Longman Corpus Network shows that these 3000 most frequent words in spoken and written English account for 86% of the language. This means that by knowing this list of words, a learner of English is in a position to understand 86% or more of what he or she reads. Of course, “knowing” a word involves more than simply being able to recognise it and know a main meaning of it. Many of the most frequent words have a range of different meanings, a variety of different grammatical patterns, and numerous significant collocations. Nonetheless, a basic understanding of the Longman Communication 3000 is a very powerful tool and will help students develop good comprehension and communication skills in English. ‘This [frequency] information is gold dust for the language learner. LDOCE shows in graphic and immediate form which words are really worth learning and knowing how to use.’ Jeremy Harmer, EL T author T o ensure that users have access to the appropriate information, the Longman Dictionary of Contemporary English marks all the words that are in the Longman Communication 3000 in red accompanied by special symbols: W1, W2, and W3 for words that are in the top 1000, 2000 and 3000 most frequent words in written English, and S1, S2 and S3 for the top 1000, 2000 and 3000 most frequent words in spoken English. Nowadays, many learner’s dictionaries include information about the most frequent words in English, but Longman dictionaries are the only ones to highlight the differences between spoken and written frequency.These frequency markers added to the headwords in the dictionary give users access to a wealth of information that can help the selection of the appropriate word or phrase in a variety of situations. Not only are the words and meanings given descriptive labels, for example formal or informal, AmE (American English) or BrE (British English), humorous, old-fashioned, but now they have the added information about relative frequency in spoken and written language. T ake for example the verb book (in the meaning of book a table at a restaurant). It is marked as S2 – one of the top 2000 words of spoken English. Note that is has no marker for written English because according to corpus analysis, it is not part of the top 3000 most frequent words in written English. However, the entry also indicates that a synonym for book is reserve which is in the top 3000 most frequent words in written English. The conclusion to be drawn from this is that in speaking (for instance when phoning a hotel or restaurant), book is the most appropriate verb to use when asking for a room or table to be kept for you. In writing, however, it would be more appropriate to use reserve. ‘There are two distinct modes of English: thoughtful, accurate and more formal, reflected mostly by written English; and spontaneous, real-time, less formal language, typified by spontaneous speech and some informal writing.’ Professor Geoffrey Leech, Emeritus Professor of English Language and Linguistics – University of Lancaster Learning a language can be exciting, but also sometimes difficult and frustrating because there are so many things to learn and it is difficult to know what to focus on. The frequency markers that identify the Longman Communication 3000 help students see clearly which words are frequent in written and spoken English, and enable them to focus more attention on mastering the meanings, grammatical patterns and collocations of these words.
