构词法课件初中篇1:构词法课件初中构词法课件初中学习目标:1. 了解英语单词的三大构词法重点学习合成法;派生法转化法2. 学习重难点:学习合成法;派生法转化法学习过程:1. 英语构词法之一:合成法利用复合法构成的单词,是由两个各自本身有意思的词,组合在一起,拥有一个新的意思。

例如:classmate(同班同学)= class(班级) + mate(同伴)类似的`单词还有许多,根据这个方法可以让自学单词:同事workmate 校友schoolmate 同桌deskmate 合成名词的构成方法1.动词+副词get-together 聚会2.副词+动词ine 收入output 产量,输出3.名词+名词apple tree 苹果树boy student 男生woman doctor合成形容词的构成方法1.形容词+名词-ed warm-hearted 热情的kind-made 手工的left-handed 左手的2.名词+过去分词man-made 人造的hand-made 手工的water-covered 被水覆盖的3.副词+过去分词well-known 著名的highly-developed 高度发展的4.形容词+现在分词good-looking 漂亮的easy-going 随和的5. 副词+现在分词hard-working 辛劳的2.英语构词法之二:派生法形象地说“派生法”就是从一个单词引申出另外一个新词。

学生也会发现许多单词加一些词缀就成了另一个词,什么叫词缀呢?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2.后缀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。

3.英语构词法之三:转化法转化法,顾名思义,就是把单词的一种词性转化成另一种词性。

这样的单词在英语里有许多许多。

因为单词本身的组成没有改变,只是词性进行改变,记忆起来更加容易。
