學習構詞法基礎知識是非常有好處的，它可以使我們能夠輕松認識更多單詞，以一種巧妙的方式擴大詞匯量，短期內記住更多的單詞。今天，就一起來學習構詞法的基礎知識吧！英語中的構詞法主要有三種，即轉化法、合成法和派生法。一. 轉化法在英語中，一個單詞由一種詞性轉化為另一種或幾種詞性而詞形不變的方法叫做轉化法。1. 動詞轉化為名詞●Let me have a?try.讓我試試。●They are only allowed to sell soft?drinksat school.在學校里只準許他們出售不含酒精的飲料。2. 名詞轉化為動詞●He?shoulderedhis way through the crowd.他用肩膀推開人群前進。●The smell from the kitchen made his mouth?water.從廚房傳來的氣味使他流口水。3. 形容詞轉化為動詞●We will try our best to?betterour living conditions.我們要盡力改善我們的生活狀況。●They tried to?perfectthe working conditions.他們努力改善工作條件。4. 形容詞轉化為名詞●He didn’t know the difference between?rightand?wrong.他不辨是非。●The?oldin our village are living a happy life.我們村的老年人過著幸福的生活。5. 形容詞轉化為副詞●How?longhave you lived there?你在那兒住多久了？6. 個別詞在一定場合中可轉化為名詞●Warm clothes are a?mustin the mountains.穿暖和的衣服到山區(qū)去是必須的。●Life is full of?upsand?downs.人生有得意時也有失意時。●His argument contains too many?ifsand?buts.他的辯論中含有太多的“如果”和“但是”。二. 合成法由兩個或兩個以上的單詞連在一起合成一個新詞，這種構詞法叫做合成法，合成的詞叫做合成詞。合成詞一般看其詞，知其意。1. 合成名詞●名詞/代詞+名詞?newspaper blood-test she-wolf●動詞+名詞?typewriter pickpocket daybreak●形容詞+名詞?greenhouse highway●副詞+名詞?overcoat outside●名詞+v.-ing/v.-ing +名詞?handwriting reading-room freezing-point●動詞+副詞/ 副詞+ 動詞?breakthrough get-together outbreak outcome●名詞+介詞+名詞?sister-in-law editor-in-chief2. 合成形容詞●名詞+形容詞/形容詞+名詞?world-famous duty-free large-scale long- term●副詞+形容詞?over-anxious evergreen●名詞+過去分詞?man-made sun-burnt●名詞+現(xiàn)在分詞?peace-loving English-speaking●形容詞+現(xiàn)在分詞?good-looking easy-going●副詞+過去分詞?well-informed widespread●副詞+現(xiàn)在分詞?hardworking far-reaching●形容詞+名詞+ed?warm-hearted absent-minded●數(shù)詞+名詞+ed?three-legged ten-storied●數(shù)詞+名詞?one-way five–star●數(shù)詞+名詞+形容詞?ten-year-old 800-meter-long●名詞+to+名詞?face –to-face door - to -door3. 合成動詞●名詞+動詞 baby-sit sleepwalk●副詞+動詞?outnumber underestimate overwork●形容詞+動詞?whitewash4. 合成副詞●形容詞＋名詞?meanwhile anyway●形容詞＋副詞?everywhere anyhow●副詞＋副詞?however●介詞＋名詞?beforehand overhead●介詞＋副詞?forever5. 合成代詞●代詞賓格＋self/selves?herself themselves●物主代詞＋self/selves?myself yourselves●形容詞＋名詞?anything nothing6. 合成介詞●副詞＋名詞?inside outside●介詞＋副詞?without within●副詞＋介詞?into三. 派生法由一個詞加上前綴或后綴構成一個與原單詞意義相近或截然相反的新詞叫做派生法。1. 前綴除少數(shù)前綴外，前綴一般改變單詞的意義，但不改變單詞的詞性。（1）表示否定意義的前綴●un- unhappy unfinished undress●dis- disagree disbelieve●in- [il-(在字母l前)，im- (在字母m,b,p前)，ir- (在字母r前)] inaccurate illegal impolite imbalance irregular●mis- misbehave mislead mistake●non- nonstop nonsmoker（2）表示其他意義的前綴●en- “使……”?enrich enlarge encourage●inter- “相互”international intercontinental●re- “再，又，重”?rethink retell recycle●tele- “遠程的”?telescope telephone telegraph●auto- “自動的”?automatic automobile●co- “共同”?coworker cooperate coexist●anti- “反對，抵抗”?antiwar antifreeze antinuclear●multi- “多”?multistory multicultural multicolor●bi- “雙，二”?bicycle bilingual bilateral●micro- “極小的，微小的”?microwave microcomputer●over- “太多，過分”?overwork overdo overestimate●self- “自己，本身”?self-centered self-confident self-control●under- “在……下面，……下的，不足的”?underline, underground, underestimate, underrate2. 后綴（1）形容詞后綴●-able “可……的，具有……的”?acceptable drinkable knowledgeable reasonable●-al “與……有關的”?physical, magical, political●-an “屬于某地方的人”?American African●-ern “方向”?southern, northern, eastern●-ful/ less “（沒）有……的”?helpful, useful, homeless, hopeless●-ish “如……的；有……特征的” foolish childish selfish●-ive “有……傾向的”?active attractive expensive●-en “由……制成的”?golden wooden woolen●-ous “有（性質）的”?famous, dangerous, poisonous●-ly “有……性質的”?friendly yearly daily●-y “構成形容詞”?noisy dusty cloudy（2）名詞后綴●-er / or “表人或用具”?farmer, baker, visitor, professor, cooker, container●-ese “某國（人）的”?Chinese, Japanese●-ian “某國、某地人；精通……的人” musician, Asian, Russian, technician●-ist “某種主義或職業(yè)者”?physicist, scientist, communist，socialist●-ess “表女性，雌性”?hostess, actress, princess●-ment “行為或其狀態(tài)”?government, movement, achievement●-ness “性質，狀態(tài)”?illness, sadness, carelessness●-tion “動作，過程，結果”?invention, organization, translation●-ance/ ence “抽象；行為、性質、狀態(tài)” importance, appearance, absence, existence●-th “性質、情況”?depth, warmth, truth●-ful “（滿的）量”?handful, spoonful, mouthful●-(a)bility “抽象、性質、狀態(tài)”?possibility, disability, reliability●-al “過程、狀態(tài)”?survival, arrival, approval●-y “性質、情況”?modesty, delivery, honesty●-dom “處于……狀態(tài)；性質” freedom, boredom●-age “狀態(tài)，行為，身份及其結果”?courage, storage, marriage（3）動詞后綴●-fy / ify “使得；變得” simplify, beautify, purify●-en “使成為；變得” shorten, deepen, sadden●-ize “使成為”?apologize, realize, specialize（4）副詞后綴●-ly “方式，程度”?freely, truly, angrily●-ward(s) “向……”?towards, forward, upwards（5）數(shù)詞后綴●-teen “十幾” fourteen, eighteen, thirteen●-ty “整十位數(shù)” forty, fifty, sixty●-th “序數(shù)詞” twelfth, twentieth微信公眾號搜索：?北京小學學習資料? ? ?家長升學指南??關注公眾號，獲取最新資訊！? ?
