英语中构成单词的方法常有合成、派生、转化词义等几种。下面请走进构词法专列逐项欣赏:

一、合成词汇展厅

合成词,又名复合词,因由两词(或多词)合并成一词(词与词之间也可以有连字符)而得名;其中合成名词是标准的大家庭,其次是合成形容词,合成介词、副词、数词等也“人才辈出”。

A. 合成名词网页grandchildren, afternoon, volleyball, washroom, policeman, keyboard, goodbye, pencilbox, postman, breakfast, etc.

B. 合成形容词网页English-speaking, Chinese-English, etc.

C. 其它合成词网页something, everybody, sometimes, twenty-first, yourself, etc.

列车员:春天到,杨柳青青树枝发——英语中也有不少“词干”通过加前缀或后缀,“长出”串串“派生词”!请瞧好了……

二、派生词小观园

所谓派生词,就是由词根加前缀或后缀重组而成:如like(像)-unlike(不像),加前缀,一般不导致词类(性)转变,而只是引起意义上的变化,故有加前缀便可能构成反义词之说;near(adj.)-nearly(adv.),加后缀,意义变化不大,只改变了词类(性);其中以名词、形容词的后缀最多,加上副词、数词的后缀合称四大常见后缀。

A. 后缀主页其中以名词后缀(像-ness,-tion,-ian,-ure,-ing等)、形容词的后缀(像-ful,-ed,-less,-able等)居多;它们与副词后缀(-ly)、数词的后缀(像-teen,-ty,-th等)合称“四大名缀”。

a. 名词后缀网页good-goodness; play-player; America-American; build-building; please-pleasure; different-difference; etc.

b. 形容词后缀网页friend-friendly; England-English; close-closed; etc.

c. 副词、数词等后缀网页certain-certainly; eight-eighteen; eighty-eighteenth; etc.

B. 前缀主页like-dislike; happy-unhappy; etc.

列车员:词汇大家族里还有不少“双重身份”者:它们既服役于此词类,一转身又去另一方面军效劳,人称“转化词或兼类词”。眼见为实,一起去看看……

三、转化词全家福

A. 动词→名词方队

water浇水 / 水,break打破/休息,go去/试,watch观看/手表,boat划船/船,cook煮饭/厨师,etc.

注:look, talk, rest, swim, try, read等动词常用于have / take a...结构中作名词。

B. 动词→形容词方队

open开/开着的;clean擦洗/干净的;etc.

C. 名词→形容词方队

light灯/轻的;淡的(颜色);orange桔子;桔红色/桔红色的;Chinese中国人/汉语 / 中国的;etc.

D. 其它转化词方队

dear亲爱的/昂贵的;like喜欢/像;etc.

注:多数词仅词性变化,如:work v. & n.工作,yellow adj. & n.黄色(的);thank v. & n.感谢;that pron. & adj.那(个), etc.

四、体验性自测题:
