六大英语构词法详解22539

英语构词通常包括六种方法:转化法、派生法、合成法、混合法、截短法和首尾字母结合法。 一、【派生法】 英语构词法中在词根前面加前缀或在词根后面加后缀,从而构成一个与原单词意义相近或截然相反的新词的方法叫作派生法。 1.前缀 除少数英语前缀外,前缀一般改变单词的意义,不改变词性;英语后缀一般改变词类,而不引起词义的变化。 (1)表示否定意义的前缀常用的有dis-, il-, im-, in-, ir-, mis-, non-, un-等,在单词的前面加这类前缀常构成与该词意义相反的新词。例如: agree同意→disagree不同意 fair公平的→unfair不公平的 possible可能的→impossible不可能的 understand理解→misunderstand误解 (2)表示其他意义的前缀常用的有a-(多构成表语形容词), anti- (反对;抵抗), auto- (自动), co- (共同), en- (使), inter- (互相), re- (再;又), sub- (下面的;次;小), tele- (强调距离)等。例如: co-worker 同事,帮手 enlarge 使变大 cooperate 合作 rewrite 重写

subway 地铁 2.后缀 给单词加后缀也是英语构词的一种重要方法。后缀通常会改变单词的词性,构成意义相近的其他词性;少数后缀还会改变词义,变为与原来词义相反的新词。下面仅作简单介绍。 (1)构成名词的后缀常用的有-ence,-(e)r/ -or (从事某事的人),-ese (某地人),-ess (雌性),-ian (精通……的人),-ist (专业人员),-ment (性质;状态),-ness (性质;状态),-tion(动作;过程)等。例如: differ不同于→difference区别 write写→writer作家 China中国→Chinese中国人 act表演→actress女演员 music音乐→musician音乐家 (2)构成动词的后缀常用的有-(e)n (多用于形容词之后),-fy (使……化),-ize (使……成为)。例如: wide→widen加宽 beauty→beautify美化 pure→purify提纯 real→realize意识到 organ→organize组织 sharp→sharpen使变锋利 (3)构成形容词的后缀常用的有-al,-able (有能力的),-(a)n(某国人的),-en (多

最新初中英语常用构词法归纳

英语专题讲座(一) 词汇的分类和构词法 一、复习要点阐述 我们学习的语言的每一篇文章都是由句子构成的。每一个句子都是由或多或少的词构成的。单词是语言构成的最基础内容,教英语的老师通常会说“一个学生记住的词汇是与他的英语成绩成正比。”这句话说明了一件事,就是词汇量的重要性。就像我们自己的国语中文,一个孩子从小到大,在日常生活中记住了大量的词汇,所以运用起来很自如。如何能记好英语的单词及其他们的用法,了解英语的词类和构词法对于一个考生来说是很重要的。所以在今天的专题中,我们将复习英语的词类和初中阶段我们所要掌握的几种构词法,使同学们对英语的词类及其简单的用法有一定的了解,并能正确的使用词汇。 二、要点复习的策略及技巧 (一)英语的词类 英语中的词类根据其语法功能分为名词、冠词、代词、数词、副词、介词、连词、感叹词、动词十类。根据意义又可以分为实词和虚词。实词指具有实际意义并能单独作句子成分的词。这些词是名词、数词、代词、形容词、副词和动词六类。虚词指没有实际意义或实际意义不明显、不能在句子中单独作句子成分的词。这些词是冠词、介词、连词和感叹词四类。 下面我们就词汇的分类、名称、作用及例词列表。

从上面的表格中我们简要地讲解了英语十大词类的基本用法。同学们可以仔细的体会一下此表的内容。这将有助于你们对句子和文章的理解。 (二)构词法 语言的基本要素之一是词汇。在语言发展的最初阶段,人们使用的是少量而简单的词汇,这些词汇只表示日常简单的事物和概念,构成语言最基本的词,称为原生词,也叫基本词或词根词。英语里的原生词大都是单音节的。如:sun, man, head, foot, fish, see, run等,其数量是有限的。随着社会的发展与进步,语言的扩充与融合使语言变得复杂,原有的原生词已不够用,人们便创造了一些新词来表示新有的事物与概念,按照语言一定的规律创造新词的方法,就是我们所说的构词法。在初中阶段我们学习了下列构词法,了解了这些构词法,我们对词的用法就更方便一些。 1. 合成法 合成法至今保持着旺盛的生命力,在现代英语中不少新词都是借助原有的词合成的。 1)名词+名词→名词 basket(篮子)+ball(球)→basketball篮球book (书) +shop(商店) → bookshop书店 book(书) + store(商店) → bookstore书店house(房子) +work(劳动) → housework家务劳动 home(家庭) + work(工作) → homework家庭作业 2) 形容词+名词→名词 black(黑色的)+board(木板)→ blackboard黑板English(英国的)+man(人)→ Englishman英国人 loud(大声的)+speaker(说话者) → loudspeaker扬声器 3)动词的-ing形式+名词

Please hand me the book.请把那本书递给我。 ③某类人的名词可以用作动词来表示动作,如: She nursed her husband back to health.她看护丈夫,使他恢复了健康。 ④某些抽象名词也可作动词。如: We lunched together.我们在一起吃了午餐。 3)形容词转化为动词 有少数形容词可以转化为动词。如: We will try our best to better our living conditions.我们要尽力改善我们的生活状况。 4)副词转化为动词 有少数副词可以转化为动词。例如: Murder will out.(谚语)恶事终必将败露。 5)形容词转化为名词 ①表示颜色的形容词常可转化为名词,如: You should be dressed in black at the funeral.你在葬礼中该穿黑色衣服 ②某些形容词如old, young, poor, rich, wounded, injured等与the连用,表示一类人,作主语时,谓语用复数如下,如: The old in our village are living a happy life.我们村的老年人过着幸福的生活。 2.派生法

英语构词法

Ⅰ.构词法(Word Formation) A.词根(Root) B.派生词(Derivative) C.合成词(Compound Words) 词是什么? “词”的英语是“Word”。依据词典“Word”可译为“语言、言、话、字、文字、词”等。人类在学习一种语言时最基本的两件事就是认识词和使用词来表达思想。 那么“Word”是什么? 我们先从表达思想来说。大凡人要把心中所感觉到的和所想的表达出来时,一个共通的表达模式就是“举出主题并说明它”。这种表达模式我们叫做“一句话”,在语言学上称为句子(Sentence)。例如: 例A:Your book is on the desk. (你的书在书桌上。) 例B:Tom goes to school by bicycle every day. (汤姆每天骑自行车上学。) 例C:The lady who has just passed by is our English teacher. (刚经过的那位女士是我们的英语老师。) 解说:上面各例都是句子。例A是表示我们生活中周边的静态事物,例B是表达事物的动态现象,例C所表达的是两者都有。那么句子是由什么来组成的呢?由上面各例可以了解句子的组成要素如下: 由上面的解说我们可以了解: 定义:词、短语、从句等称为句子组成的要素(Element)。 词是句子的组成要素中不能再细分的最小表意单位(Sense unit)。 构词法 英文词和中文词的最大不同点在于中文词是属于象形文字语系,字形是固定不变,而且是一字一音;英文词是属于符号文字语系,其字形(拼写法)须配合语意和句意表达的条件并受其约束,同时有一字一音、一字二音、一字三音……等。请参考下列的中英文词对比。 上面对比表中所列示者只是英文词的基本变化部分,实际上英文词的词形变化还不止这些。语言学家把这种专门研究词形变化现象和规则的学问称为词形学(Morphology),通常简称为构词法(Word Formation)。 构词法基本上包括下列三项: 1.词根(Root) 2.派生词(Derivative) 3.合成词(Compound Words) A.词根(Root) 定义:英文词形成的“根基”部分称为词根(亦称字根)。 现以“like”为例列示如下: Root like................................................... 像 a-like.................................................... 相像 un-like................................................... 不像 like-ness............................................ 相像 un-like-ness............................................ 互不相像 解说:如例所示“like”就是“alike…unlikeness”等词的词根。因英文词源自拉丁语者约占五分

英语中的构词法详解及记忆大全

英语构词通常包括六种方法:转化法、派生法、合成法、混合法、截短法和首尾字母结合法。 一、【派生法】 英语构词法中在词根前面加前缀或在词根后面加后缀,从而构成一个与原单词意义相近或截然相反的新词的方法叫作派生法。 1.前缀 除少数英语前缀外,前缀一般改变单词的意义,不改变词性;英语后缀一般改变词类,而不引起词义的变化。 (1)表示否定意义的前缀常用的有dis-, il-, im-, in-, ir-, mis-, non-, un-等,在单词的前面加这类前缀常构成与该词意义相反的新词。例如: agree同意→disagree不同意 fair公平的→unfair不公平的 possible可能的→impossible不可能的 understand理解→misunderstand误解 (2)表示其他意义的前缀常用的有a-(多构成表语形容词), anti- (反对;抵抗), auto- (自动), co- (共同), en- (使), inter- (互相), re- (再;又), sub- (下面的;次;小), tele- (强调距离)等。例如: co-worker 同事,帮手 enlarge 使变大 cooperate 合作 rewrite 重写 subway 地铁

2.后缀 给单词加后缀也是英语构词的一种重要方法。后缀通常会改变单词的词性,构成意义相近的其他词性;少数后缀还会改变词义,变为与原来词义相反的新词。下面仅作简单介绍。 (1)构成名词的后缀常用的有-ence,-(e)r/ -or (从事某事的人),-ese (某地人),-ess (雌性),-ian (精通……的人),-ist (专业人员),-ment (性质;状态),-ness (性质;状态),-tion(动作;过程)等。例如: differ不同于→difference区别 write写→writer作家 China中国→Chinese中国人 act表演→actress女演员 music音乐→musician音乐家 (2)构成动词的后缀常用的有-(e)n (多用于形容词之后),-fy (使……化),-ize (使……成为)。例如: wide→widen加宽 beauty→beautify美化 pure→purify提纯 real→realize意识到 organ→organize组织 sharp→sharpen使变锋利 (3)构成形容词的后缀常用的有-al,-able (有能力的),-(a)n(某国人的),-en (多用于表示材料的名词后),-ern (方向的),-ese(某国人的),-ful,-

英语基本构词法

英语基本构词法 英语最基本的构词法(word formation)有三种:派生(derivation)、合成(compounding)和转化(conversion)。利用构词法记忆单词,可以记忆成串,举一反三。 Ⅰ.派生法 派生词缀和词根结合,或者粘着词根和粘着词根结合构成单词的方法,叫做派生法(derivation),也称作缀词法。用派生法构成的词叫做派生词(derivative)。派生词的词缀法是英语构词法中最活跃的一种,在英语构词的历史上发挥极其重要的作用。另外,这种构词法也是我们可以发挥能动性借以扩大词汇量的一种构词法。词缀分为前缀和后缀两种。 A.前缀 1.表示“否定”、“相反”意义的前缀: de- decrease减少;decentralize分散;degrade降级,降低……的地位; dis- dislike不喜欢;disagree不同意;distrust不信任;disappear消失; il- illegal不合法的;illogical不合逻辑的;illegalize宣布……为非法; im- impossible不可能的;immoral不道德的;impractical不现实的; un- unwilling 不情愿的;unbelievable 难以置信的;unnecessary 不必要的等等。 2.表示时间先后的前缀 ex- ex-husband前夫;ex-president前总统; fore- foretell语言;foresight先见之明,预见;foresee预见,预知; mid- midterm其中的;midnight午夜; post- postwar战后的;postgraduate研究生;postdoctoral博士后的等等。 3.表示方向位置的前缀 ex- export出口;exclude把……排斥在外;external外部的; in- input输入;indoor室内的;inrush涌入;incoming进来的等等。 4.表示程度的前缀 extra- extraordinary非凡的,惊人的;extracurricular课程以外的; out- outnumber比……多;outrun超过,跑得比……快; sur- surpass超过,优于;surplus剩余的;surrealism超现实主义等等。 5.表示数量的前缀 bi- bilateral双边的,两边的;bipartisan两党的;bilingual两语的; mono- momocycle独轮车;monologue独白;monodrama独角戏,单人剧;

英文构词法讲解

英文构词法 按照语言一定的规律创造新词的方法叫作构词法。英语构词法主要有转化法、派生法、合成法、混合法、截短法和首尾字母结合法六种, 一、转化法 英语中,有的名词可作动词,有的形容词可作副词或动词,这种把一种词性用作另一种词性而词形不变的方法叫作转化法。 1.动词转化为名词 很多动词可以转化为名词,大多意思没有多大的变化(如下①);有时意思有一定变化(如下②);有的与一个动词和不定冠词构成短语,表示一个动作(如下③)。例如: ①Let's go out for a walk.我们到外面去散散步吧。 ②He is a man of strong build.他是一个体格健壮的汉子。 ③Let's have a swim.咱们游泳吧。 2.名词转化为动词 很多表示物件(如下①)、身体部位(如下②)、某类人(如下③)的名词可以用作动词来表示动作,某些抽象名词(如下④)也可作动词。例如: ①Did you book a seat on the plane?你订好 飞机座位了吗? ②Please hand me the book.请把那本书递给我。 ③She nursed her husband back to health.她 看护丈夫,使他恢复了健康。 ④We lunched together.我们在一起吃了午餐。 3.形容词转化为动词 有少数形容词可以转化为动词。例如: We will try our best to better our living conditions.我们要尽力改善我们的生活状况。 4.副词转化为动词 有少数副词可以转化为动词。例如: Murder will out.(谚语)恶事终必将败露。 5.形容词转化为名词 表示颜色的形容词常可转化为名词(如下①);某些形容词如old, young, poor, rich, wounded, injured等与the连用,表示一类人,作主语时,谓语用复数(如下②)。例如: ①You should be dressed in black at the funeral.你在葬礼中该穿黑色衣服。 ②The old in our village are living a happy life.我们村的老年人过着幸福的生活。 二、派生法 在词根前面加前缀或在词根后面加后缀构成一个与原单词意义相近或截然相反的新词叫作派生法。 1.前缀 除少数前缀外,前缀一般改变单词的意义,不改变词性;后缀一般改变词类,而不引起词义的变化。 (1)表示否定意义的前缀常用的有dis-, il-, im-, in-, ir-, mis-, non-, un-等,在单词的前面加这类前缀常构成与该词意义相反的新词。例如:appear出现→disappear消失 correct正确的→incorrect不正确的 lead带领→mislead领错 stop停下→non-stop不停 (2)表示其他意义的前缀常用的有a-(多构 成表语形容词), anti- (反对;抵抗), auto- (自动), co- (共同), en- (使), inter- (互相), re- (再;又), sub- (下面的;次;小), tele- (强调距离)等。例如: alone单独的antigas防毒气的 autochart自动图表 cooperate合作enjoy使高兴 internet互联网reuse再用 subway地铁telephone电话 2.后缀 英语单词不仅可以通过加前缀构成新词,也可加后缀构成新词。后缀通常会改变单词的词性,构成意义相近的其他词性;少数后缀还会改变词义,变为与原来词义相反的新词。

英语构词法详细讲解

构词法 一、转化法(兼类词):指在不同的语境中,名词动用,动词名用等。 如:https://www.wendangku.net/doc/984078440.html,ok was the first to map (v.)the east coast.(库克是第一个画西部海岸地图的人) 2.The house can house (v.)many people.(这房子可以住下好多人) 二、合成词:英语中的合成词有合成形容词、合成名词、合成动词、合成副词、合成动词、合成代词等, 如:合成形容词:well-known, warm-hearted, easy-going 合成名词:raincoat, earthquake, waterfall,blackboard, classroom, motherland 合成动词:underline, overcome, 合成副词:maybe, wherever, however, therefore 合成代词:himself, everyone, nobody 三、派生法(词缀法或缀合法),这种词是最为活跃的一种,大约三分之二的英语单词是用这种方法构成的。因此,掌握一些常用派生词的构词规律对于我们正确拼写单词和在阅读中猜词能力的培养就显得尤为重要。在英语的派生词中,词根决定词的根本意义,前缀改变词义,后缀引起词类的的改变(个别后缀还会改变词义) 1.名词后缀 -er:writer, teacher, manager, worker, employer, interviewer -ee: employee, interviewee -or:actor, sailor, editor, beggar, operator -ian:librarian, American, physician -ist:scientist, physicist, artist, cyclist, typist, biologist, geologist -ese:Chinese, Japanese (-er, -ee,-or, -ian, -ist, -ese: 表示“从事某种职业或来自------的人” ) -ism:Marxism, socialism, nationalism, communism (-ism表示----主义) -ess:actress, waitress, hostess (-ess表示性别) -ness:happiness, illness, coldness, carelessness, sickness -ment:movement, agreement, achievement, appointment, adjustment -ship:friendship, hardship(困苦、苦难、艰难困苦) -ion:education, decision, communication, impression, description, collection -ity:reality, purity, responsibility, possibility -ance(ence):performance, independence, science , violence, reference, appearance -ure:failure, departure(分离,分开) -al:arrival,survival, signal -hood:childhood, boyhood, neighborhood, livelihood -th: truth, depth, (-ism, -ess, -ness, -ment, -ship, -ion, -ity, -ance(ence), -ure, -al, -hood, -th: 表示“行为的过程、状态或性质”) 2.形容词后缀 -less: hopeless, endless, careless, helpless, (表“否定”) -ful: useful, careful, hopeful, grateful, powerful -ous:dangerous, humorous, cautious, infectious -able:enjoyable, comfortable, considerable, admirable, unforgettable -y:snowy, dirty, greedy, rainy, sunny, guilty -ent(-ant):different, independent, confident, violent, efficient, distant
