许多英语单词的构成都有一定的规律，这种规律被称为构词法。掌握构词法知识对我们更好地理解词义、认识新词和扩大词汇量都有重要意义。英语中的构词法有合成法、派生法和转化法三大类。一、合成法由两个或两个以上的单词合成的词叫合成词，这种构词法称为合成法。最常见的合成法包括：合成名词、合成形容词、合成动词。词与词之间有的用连字符连接，有的直接连接在一起。
1.合成名词的常见结构(1)名词＋名词　bedrm卧室；sprtsman男运动员；lifebat救生船(2)名词＋动词-ing　handwriting书法；sightseeing观光；sunbathing日光浴(3)形容词＋名词　hardware硬件；midnight午夜；gentleman绅士(4)动词-ing＋名词　writing-paper书写纸；hiding-place藏身处；swimming-pl游泳池(5)动词＋名词　watchdg看家狗；pickpcket扒手；playgrund操场(6)名词＋动词　snwfall降雪；daybreak黎明；waterdrp水滴

三、转化法(cnversin) 在词形不变的情况下，把一个单词由一种词性转换成另一种词性，而没有加任何词缀，这种构词方法称为转化法。转化法种类很多，但数量最多的是由名词转化为动词和由动词转化为名词两大类。转换后的词义与转换前的词义通常有密切的联系，但有时差异也很大。例如：dream v.做梦→n.梦lk v.看→n.相貌back n.后背→v.支持air n.空气→v.通风
1.许多名词可转化成动词，意思也随着有些改变。如：chair(n.椅子→ v.主持)　hand(n.手→v.递，交)land(n.土地→v.着陆)　ck(n.厨师→v.烹调)rder(n.命令→v.订购)　name(n.名字→v.取名)lift(n.电梯→v.举起)　picture(n.画→v.描绘)press(n.报刊→v.挤压)　nurse(n.护士→v.照料)smke(n.烟→v.吸烟)　stand(n.看台→v.站)2.大量动词可转化为名词，有时意思没有太大改变。如：try(v.尝试→n.尝试)　swim(v.游泳→n.游泳)sigh(v.叹气→n.叹气)　cry(v.哭→n.哭)shut(v.呼喊→n.呼喊)　kiss(v.吻→n.吻)

5.形容词转化成副词。如：deep(adj.深的→adv.深深地)wide(adj.宽的→adv.广泛地)hard(adj.困难的→adv.努力地)well(adj.健康的→adv.很好地)
