Module 12 Save our worldUnit 3 语法专项英语构词法知识精讲构词法就是按照一定规律来创造新词的方法。
学习英语构词法基础知识很有用，不仅使我们深刻理解英语单词的形成规律，还可以让我们学会举一反三，更巧妙地记忆单词，扩大词汇量。
英语构词法主要有三种：转化法、合成法和派生法。
其中，合成法也叫复合法。
1.转化法英语中，有些单词兼有多个词性。
把一个单词由一种词性转换为另一种或几种词性而词形不变，但有时候会有发音方面的细微变化（主要是重音的转移）。
这种构词方法就叫转化法。
（1）名词转化为动词book n. 书book v. 预定back n.后背back v.支持hand n. 手hand v.交给nurse n. 护士护理water n.水water v.浇水（2）动词转化为名词drink v.喝drink n.饮料look v.看look n. 看talk v.说话talk n.谈话walk v.走路walk n. 步行，散步try v.尝试try n.试图，努力go v. 去go n. 尝试，努力（3）形容词转化为名词light adj. 明亮的light n.光，光线right adj. 正确的right n. 正当；权利；右边wrong adj. 错误的wrong n. 坏事；错误的或不公平的行为young adj. 年轻的young n. 年轻人（the young）old adj.年老的old n. 老年人（the old）（4）形容词/副词转化为动词slow adj.慢的slow v.放慢perfect adj. 完美的perfect v.使完美better adj./adv.better v. 使更好，改善，改进（5）形容词转化为副词enough adj. 足够的enough adv. 足够地long adj. 长的;long adv. 长久地straight adv. 直的straight adv.直地hard adj. 硬的;困难的;hard adv. 努力地；猛烈地2.合成法/复合法由两个或两个以上独立且意义不同的单词连在一起合成一个新词，一般来说，前一个词修饰或限定后一个词，这种构词法叫做合成法，也叫复合法。
合成的词叫合成词或复合词。
合成词一般看其词，知其意。
（1）合成名词●名词+名词weekday(工作日)，weekend(周末)，newspaper(报纸)●代词+名词shewolf（母狼），shegoat（母山羊）●形容词+名词blackboard(黑板), freshman(大一新生)●副词+名词 overcoat(外套)，downstairs(底楼，楼下；此词还可做adj.或adv.)●动词+名词typewriter(打字机)●动名词+名词readingroom(阅览室)，swimmingpool（游泳池）●名词+动名词handwriting（书写），sightseeing (观光，游览)●动词+副词breakthrough（突破）， gettogether（聚会）●副词+ 动词outbreak(战争、疾病等爆发) , oute(结果，效果)●名词+介词+名词 motherinlaw(婆婆) editorinchief（主编）（2）合成动词●名词+动词 babysit（看孩子） sleepwalk （梦游）●形容词+动词 whitewash（粉刷）●副词+动词 outnumber(数目超过) ，overwork (过度工作)，underestimate(低估)（3）合成形容词●名词+形容词 worldfamous(世界著名的), dutyfree(免税的)●形容词+名词largescale(大规模的), long term(长期的)●副词+形容词 overanxious(过度焦虑的), evergreen(长青的)●名词+过去分词 manmade（人造的）, handmade(手工的), stateowned(国有的)●名词+现在分词 peaceloving(爱好和平的)，Frenchspeaking(讲法语的)●形容词+现在分词 goodlooking(好看的) ， easygoing（随和的）●副词+过去分词 welleducated(受过良的)，wellknown(著名的)●副词+现在分词 hardworking(努力工作的) , farreaching(广泛的)●形容词+名词+ed warmhearted(热心的) , absentminded(心不在焉的)●数词+名词+ed threelegged(三条腿的) tenstoried(十层楼高的)●数词+名词+形容词 eightyearold(八岁大的) 700meterlong(七百米长的)（4）合成副词●形容词＋名词 meanwhile(与此同时)，anyway(不管怎样)●形容词＋副词 everywhere(到处,处处)，anywhere(任何地方)，nowhere(任何地方都不,无处)●副词＋副词however(然而，但是)（5）合成代词●代词宾格＋self/selves himself herself itself themselves●物主代词＋self/selves myself ourselves yourself yourselves●形容词＋名词anything nothing everything somebody anybody nobody（6）合成介词●副词＋名词 inside outside●介词＋副词 without within●副词＋介词into3.派生法英语构词法中，在一个词根前面或后面加上一个词缀构成一个新词，这种构词法叫派生法。
加在词根前面的词缀叫前缀，加在词根后面的词缀叫后缀。
词根承载单词的基本语义。
比如impossible的词素分析如下：im(不，表否定) poss (能力,能够)ible (可能的，形容词后缀)前缀词根后缀前缀与后缀的不同作用一般来说，前缀改变词义，后缀改变词性。
如possible(可能的)是形容词，impossible（不可能的）还是形容词，但词义改变了，im是否定前缀，意为“不”，这就叫前缀改变词义；再比如possible(可能的)是形容词，possibility (可能)是名词，ty是名词词缀，这就叫后缀改变词性。
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，而不改变词义，少数后缀也可改变词义。
特殊情况特殊记，同学们记住词缀总诀：前缀改变词义，后缀改变词性。
常见的前缀和后缀汇总表ly，副词后缀carefully, happily, quickly, especially, suddenlyen(材料的) ,形容词后缀en结尾过去分词做形容词golden, wooden, woolenbroken, stolen, fallen, drunken，spokenen(使变得……)，多接在形容词之后，动词后缀widen(加宽),broaden(开扩) , shorten(缩短)，strengthen(加强)，weaken（削弱，变弱）fy(使…化), 动词后缀beautify(美化), purify(净化), qualify(有资格) ate(做,造成), 动词后缀educate(教育)，graduate(毕业), locate(位于)ise英式/ize美式(使...化) , 动词后缀realise/realize(意识到), memorise/memorize(记住), globalise/globalize(全球化)语法专练英语构词法题组A 基础过关练单选题（本大题共50小题，共分）1.Kate is girl.
