英語中構(gòu)成單詞的方法常有合成、派生、轉(zhuǎn)化詞義等幾種。下面請(qǐng)走進(jìn)構(gòu)詞法專列逐項(xiàng)欣賞：

一、合成詞匯展廳

合成詞，又名復(fù)合詞,因由兩詞(或多詞)合并成一詞(詞與詞之間也可以有連字符)而得名；其中合成名詞是標(biāo)準(zhǔn)的大家庭,其次是合成形容詞，合成介詞、副詞、數(shù)詞等也“人才輩出”。

A. 合成名詞網(wǎng)頁grandchildren, afternoon, volleyball, washroom, policeman, keyboard, goodbye, pencilbox, postman, breakfast, etc.

B. 合成形容詞網(wǎng)頁English-speaking, Chinese-English, etc.

C. 其它合成詞網(wǎng)頁something, everybody, sometimes, twenty-first, yourself, etc.

列車員：春天到，楊柳青青樹枝發(fā)——英語中也有不少“詞干”通過加前綴或后綴，“長(zhǎng)出”串串“派生詞”!請(qǐng)瞧好了……

二、派生詞小觀園

所謂派生詞，就是由詞根加前綴或后綴重組而成：如like(像)-unlike(不像)，加前綴,一般不導(dǎo)致詞類(性)轉(zhuǎn)變，而只是引起意義上的變化，故有加前綴便可能構(gòu)成反義詞之說；near(adj.)-nearly(adv.)，加后綴，意義變化不大，只改變了詞類(性)；其中以名詞、形容詞的后綴最多，加上副詞、數(shù)詞的后綴合稱四大常見后綴。

A. 后綴主頁其中以名詞后綴(像-ness,-tion,-ian,-ure,-ing等)、形容詞的后綴(像-ful,-ed,-less,-able等)居多;它們與副詞后綴(-ly)、數(shù)詞的后綴(像-teen,-ty,-th等)合稱“四大名綴”。

a. 名詞后綴網(wǎng)頁good-goodness; play-player; America-American; build-building; please-pleasure; different-difference; etc.

b. 形容詞后綴網(wǎng)頁friend-friendly; England-English; close-closed; etc.

c. 副詞、數(shù)詞等后綴網(wǎng)頁certain-certainly; eight-eighteen; eighty-eighteenth; etc.

B. 前綴主頁like-dislike; happy-unhappy; etc.

列車員：詞匯大家族里還有不少“雙重身份”者：它們既服役于此詞類，一轉(zhuǎn)身又去另一方面軍效勞，人稱“轉(zhuǎn)化詞或兼類詞”。眼見為實(shí)，一起去看看……

三、轉(zhuǎn)化詞全家福

A. 動(dòng)詞→名詞方隊(duì)

water澆水 / 水，break打破/休息，go去/試，watch觀看/手表，boat劃船/船，cook煮飯/廚師，etc.

注：look, talk, rest, swim, try, read等動(dòng)詞常用于have / take a...結(jié)構(gòu)中作名詞。

B. 動(dòng)詞→形容詞方隊(duì)

open開/開著的；clean擦洗/干凈的；etc.

C. 名詞→形容詞方隊(duì)

light燈/輕的；淡的(顏色)；orange桔子；桔紅色/桔紅色的；Chinese中國人/漢語 / 中國的；etc.

D. 其它轉(zhuǎn)化詞方隊(duì)

dear親愛的/昂貴的；like喜歡/像；etc.

注：多數(shù)詞僅詞性變化，如：work v. & n.工作，yellow adj. & n.黃色(的)；thank v. & n.感謝；that pron. & adj.那(個(gè))， etc.

四、體驗(yàn)性自測(cè)題：

做罷下列三種“體驗(yàn)性自測(cè)題”，相信大家定能從構(gòu)詞法的特點(diǎn)中獲益多多，并積極運(yùn)用于平時(shí)的知識(shí)識(shí)記中！

⒈ 形同意不同：仔細(xì)觀察轉(zhuǎn)化詞轉(zhuǎn)化前后的區(qū)別。
