Wrd Building（Ⅱ）构词法（Ⅱ）
一、派生词派生词是指在一个单词的前面或后面加一个词缀而形成的新词。1.前缀(1)常用的表示否定意义的前缀有：dis、im、in、mis、nn、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。例词：appear(出现)→disappear(消失)；pssible(可能的)→impssible(不可能的)；crrect(正确的)→incrrect(不正确的)；lead(带领)→mislead(误导)；stp(停下)→nnstp(不停的)；happy(快乐的)→unhappy(不快乐的)。
(2)常用的表示其他意义的前缀有：a(多构成表语形容词)、 en (加在某些名词或形容词前构成及物动词)、 inter (互相), re (再、又)等。例词：alne单独的；asleep 睡着的；encurage 鼓励；internatinal 国际的；review 复习。
2.后缀(1)加在某些动词之后，构成名词的后缀有：ment、ing、er、r、in、atin、sin。例词：develp(发展)→develpment(发展)；meet(遇见)→meeting(会议)；read(阅读)→reader(读者)；act(表演)→actr(男演员)；invent(发明)→inventin(发明)；explain(解释)→explanatin(解释)；prvide(提供)→prvisin(供应物)。(2)加在某些名词之后，构成形容词的后缀有：ful、y、ly。例词：care(小心)→careful(小心的)；wind(风)→windy(多风的)；friend(朋友)→friendly(友好的)；week(周，星期)→weekly(每周的)。
(3)加在某些名词后，构成与该词词义相反的形容词的后缀有：less。例词：care(小心)→careless(粗心的)；hme(家)→hmeless(无家可归的)。 (4)加在某些形容词后，构成名词的后缀有：ness。注意：以y结尾的形容词需变y为i，再加ness。例词：dark(黑暗的)→darkness(黑暗)；happy(快乐的)→happiness(幸福)。 (5)加在某些形容词后，构成副词的后缀有：ly。注意：以y结尾的形容词需变y为i，再加ly。例词：busy(繁忙的)→busily(忙碌地)；quiet(安静的)→quietly(安静地)；happy(快乐的)→happily(快乐地)。
二、转化 转化是在不改变拼写形式的基础上，由一种词性转化为另一种词性，主要有：动词转化为名词、形容词转化为副词、动词或名词等。例词：water(n.水)→ water(v.浇水)；plant(v.种植)→plant(n.植物)；fast(adj.快的)→fast(adv.快地)；dry (adj.干的) →dry(v.使变干)；green(adj.绿色的)→green(n.绿色)。
