Grammar

英語中很多單詞的構(gòu)成形式是有規(guī)律的，掌握單詞的構(gòu)成規(guī)律有助于理解和記憶詞匯。英語的常見構(gòu)詞法有合成法(Compounding)、前綴法(Prefix)、后綴法(Suffix)和轉(zhuǎn)化法(Conversion)。縮寫法和簡寫法(AbbreviationandSimplification)也是構(gòu)詞法的一種。1.派生法

派生法，又叫詞綴法，即在一個單詞前或后加上前綴或后綴，構(gòu)成新的單詞。供參考Word-formation構(gòu)詞法

Grammar(1)常見前綴：

有的前綴不僅構(gòu)成詞類的轉(zhuǎn)化，而且還會引起意思上的變化。前綴中有相當(dāng)一部分可以構(gòu)成反義詞。①表示否定意義的前綴前綴含義例詞un-不；非happy→unhappy(不高興的)usual→unusual(不尋常的)in-不；非active→inactive(不積極的)Word-formation構(gòu)詞法

Grammar前綴含義例詞im-不；非polite→impolite(不禮貌的)dis-不；非like→dislike(不喜歡)appear→disappear(消失)non-不；非smoker→non-smoker(非吸煙者)Word-formation構(gòu)詞法

Grammar②其他前綴含義例詞mis-錯誤；失誤understand→misunderstand(誤解)lead→mislead(誤導(dǎo))re-又；再；重新view→review(復(fù)習(xí))write→rewrite(重寫)inter-相互；交互；在一起net→Internet(互聯(lián)網(wǎng))national→international(國際的)connect→interconnect(相互關(guān)聯(lián))Word-formation構(gòu)詞法

Grammar(2)常見后綴：后綴通常使詞由一種詞類轉(zhuǎn)化為另一種詞類。①形容詞→副詞后綴例詞＋-lywide→widelyquiet→quietly以“輔音字母＋-y”結(jié)尾的形容詞，變y為i，再加-lyhappy→happilyangry→angrily以“輔音字母＋-le”結(jié)尾的形容詞，去掉e，再加-ysimple→simplyterrible→terribly少數(shù)以e結(jié)尾的形容詞，要去掉e，再加-lytrue→trulyWord-formation構(gòu)詞法

Grammar后綴例詞＋-yrain→rainyhealth→healthywealth→wealthyluck→lucky＋-lyweek→weeklylove→lovelyfriend→friendly＋-ousdanger→dangerous＋-fulcare→carefuluse→usefulhelp→helpful＋-lessuse→uselesscare→careless②名詞→形容詞Word-formation構(gòu)詞法

Grammar③動詞→形容詞前綴例詞＋-edinterest→interested＋-ingfollow→followinginterest→interesting＋-tive/-iveact→activeattract→attractive＋-ableenjoy→enjoyablecomfort→comfortableWord-formation構(gòu)詞法

Grammar④形容詞→名詞前綴例詞＋-nesssad→sadnesskind→kindness＋-ydifficult→difficulty＋-ityreal→realitypopular→popularity＋-ce(以t結(jié)尾的形容詞去t，再加-ce)
