大凡英语练习者,都会觉得单词难记。因而挺多英语训练先行者概括出真不少行之有效的记忆单词方法,其中几种方式就是使用构词法记单词。使用构词法记单词着实是多种极度有效的方法,妥善英语词汇的构成规律。多见的构词法有三种,此中几种叫派生法。所谓派生法,就是在词的前方添加前缀或在词的后面添加后缀形成另整个词的方式。本文针对初中所学的前缀后缀,举行归类,来个大汇总,方便初中生尤其是即将参加中考的学子们记忆,而且通过例句讲解,帮助所有人驾驭这些词的用法。这是本文分歧于剩余很多同类文章所不同的地点,严格从考纲出发,所列举的词100%是初中所学,是中考考纲所呼吁驾驭的,希望本身的付出或许帮到很多的同学。

 

 

一、前缀的作用及所学的前缀
前缀用在词根前面以变更词的含义,一般不转变词性。初中所学的前缀有:
一)否定前缀
1. un- :unhappy,unusual,unfair,unlike,unfriendly,uncomfortable,uncrowded,uneasy,unexpected,unlucky,unbelievable,unable,unforgettable。

2. im-:impolite,impossible。
3. in-:inexpensive,incorrect,informal。
4. dis-:dislike,disappointed,discover,discourage,dishonest,disappear,disbelief,disadvantage,disabled。
5. ir-:irregular。
二)其它前缀
1. re-(表明再,又):review,recycle,return,reuse,reusable,research。
2. inter-(表示在。。。。。。之间,相互):interview,internet,international。
3. under-(声明低于):underwear,underground。
4. bi-(表明两):bicycle。

如I don’t feel happy也可能说成I feel unhappy。上面的unlike是介词,而dislike是动词,在适用于时务必诱发留心。另一,包括否定前缀的词用在反义疑难句中,后面短暂的平常疑义句照样要用否定的,如:
1. That’s impossible,isn’t it?
2. He feels unlucky,doesn’t he?
二、后缀的影响及所学的后缀
后缀用在词根后面以变化词性。初中所学的后缀有:

一)动词变成名词
在一个动词后面加上某一个后缀,使之变为名词。
1).动词+er/or/ist/ress变成名词(声明动作的施行者)
A.teach-teacher,work-worker,read-reader,think-thinker,perform-performer,wait-waiter,sing-singer,play-player,cook-cooker,record-recorder,keep-keeper,listen-listener,farm-farmer,climb-climber,lead-leader,speak-speaker,report-reporter,clean-cleaner,help-helper。
B.write-writer,drive-driver,dance-dancer,ride-rider,rule-ruler,manage-manager,make-maker。

D.visit-visitor,act-actor,invent-inventor,compete-competitor,translate-translator,direct-director。
E.tour-tourist。
F.wait-waitress,act-actress。

2).动词+tion变成名词
act-action,suggest-suggestion,communicate-communication,invite-invitation,pollute-pollution,compete-competition,predict-prediction,invent-invention,prepare-preparation,protect-protection,celebrate-celebration,direct-direction,educate-education,examine-examination,inspire-inspiration,introduce-introduction,produce-production,graduate-graduation,pronounce-pronunciation。
3) .动词+ing变成名词
draw-drawing,paint-painting,build-building,say-saying,cross-crossing,happen-happening,end-ending,mean-meaning,feel-feeling,begin-beginning,open-opening。
4) .动词+ment变成名词

5).动词+ance变成名词
appear-appearance,disappear-disappearance。
6).动词+sion变成名词
express-expression,discuss-discussion,decide-decision。
在句子中,假如作主语、宾语、表语,就能把动词改为名词。自己们来看看,
用括号内所给词的恰当模式填空:
1. He is a basketball_______(play).
2. Thank you for your_________(invite).
3. The teacher is pleased with his ________(improve)in English.

二)名词变成形容词
在一个名词后面加上某一个后缀,使之变为形容词。
1).名词+ful变成形容词
thank-thankful,help-helpful,care-careful,use-useful,hope-hopeful,beauty-beautiful,wonder-wonderful,pain-painful,harm-harmful,success-successful,truth-truthful。
2).名词+less变成形容词
help-helpless,hope-hopeless,use-useless,care-careless,harm-harmless。
3).名词+y变成形容词
rain-rainy,wind-windy,snow-snowy,sun-sunny,fog-foggy,ice-icy,health-healthy,luck-lucky,noise-noisy,sleep-sleepy,thirst-thirsty,hunger-hungry。
4).名词+ly变成形容词

6).名词+ous变成形容词

10).名词以ce结尾,把ce改为t变成形容词
silence-silent,patience-patient,confidence-confident,importance-important,convenience-convenient。
在句子中,如果作表语、定语或宾补时,非常能用要把名词变成形容词。或在动词后附加某些后缀也可变成形容词。
1) .动词+ing(即当今分词)变成形容词
move-moving,care-caring,understand-understanding,burn-burning,freeze-freezing,fascinate-fascinating,embarrass-embarrassing,surprise-surprising,bore-boring,tire-tiring,excite-exciting,interest-interesting,disappoint-disappointing,frighten-frightening,boil-boiling。
2).动词+ed(即过去分词)变成形容词

3).动词+able变成形容词
understand-understandable,forget-forgettable,enjoy-enjoyable,comfort-comfortable,value-valuable,believe-believable。
动词和形容词在句子中的影响决然不同,在适用于时要有点好根据实际状况作出变化,当然也要挺好划分如今分词与过去分词所作的形容词,当今分词表明主动或正在实行,半数以上形容事物;过去分词声明被动或已经达成,多数形容人。如;
1. I am___(bore)with the____(bore)job.
2. He found the news______(excite).
3. Only when something is lost do we find it______(value).

四)形容词变成副词
除外一点形容词、副词同形的词如early/late/fast/high/far/hard等之外,大左半形容词后面加上ly变成副词,不过有些要作改变,注意差别的改变状况。
1).careful-carefully,real-really,wide-widely,wise-wisely,polite-politely,loud-loudly,gradual-gradually,general-generally,most-mostly,cheap-cheaply,special-specially,certain-certainly,sudden-suddenly,recent-recently,different-differently,complete-completely,beautiful-beautifully,total-totally,slow-slowly,quick-quickly。

3).simple-simply,gentle-gently,possible-possibly,probable-probably,comfortable-comfortably,terrible-terribly。
4).true-truly。
形容词作表语、定语、宾补,而副词作状语。试仿照:
1. That thing made(使) me happy.(形容词作宾补)
2. They are making(制作) cards happily.(副词作状语)
3. We live a happy life.(形容词作定语)
4. She seems very happy.(形容词作表语)

五)形容词变成名词
形容词后面加上后缀ness/th/ity等可变回名词。
1) .good-goodness,kind-kindness,ill-illness,sick-sickness,sad-sadness,shy-shyness,fair-fairness,busy-business,careful-carefulness,careless-carelessness。
2) .warm-warmth,long-length,wide-width,true-truth,young-youth。
3) .able-ability,active-activity,creative-creativity,popular-popularity。
形容词和名词作用区别,在适用于时要多加留神。咱们来看这两道拣选题:
1.This time he failed the exam because of his_____.
A. careB.carefulnessC. carelessD. carelessness
2.She helped to look after a/an____man.
A.ill B. sick C. illnessD.sickness
以上对表达行初中课本(人教版)所出表达的前缀后缀实行了概括,并对其用法实行了有点好的剖析,对初中生的英语练习应该有一定的协助。
