英语里通过加后缀来改变词性。 ①常见的名词后缀有: -er thinker, teacher, driver(动词变名词) -or actor, visitor, conductor(动词变名词) -ist scientist, artist, chemist, terrorist(没变) -ian musician, mathematician(没变) -ese Chinese, Japanese (没变) -ness happiness, kindness, usefulness(形容词变名词) -tion preparation, education, communication(动词变名词) -ment movement, development, improvement(动词变名词) -ion discussion, commission, television(动词变名词) -ship friendship, hardship(名词、副词变名词) -hood childhood, boyhood(没变) -dom freedom, kingdom(形容词、名词变名词) -th truth, length, width(形容词变名词)
②常见的动词后缀有 -ize realize, modernize, apologize(形容词或名词变为动词) -en widen, shorten, deepen(形容词变为动词)
③常见的形容词后缀有 -ful useful, careful, wonderful(动词变形容词) -less careless, useless, helpless(动词变形容词) -ous dangerous, curious好奇的(名词变为形容词) -ly friendly, lovely(名词或动词变为形容词) -y rainy, sunny, snowy(动词变为形容词) -able comfortable, acceptable(动词或名词变为形容词)
动词变成名词后一般会有这几种类型: 1.名词和动词同形:
比较容易理解,这类词也比较多,如:
care,既可做动词, 意为:关心,担心,也可以当名词,意为:当心,小心,注意。
certificate,既可做动词,意为:用证书证明(认可),也可以当名词,意为:证明书,执照。
2.表示动作结果:
换言之,就是与这个动作相应的行为产生的条件的具体反应。如LZ所提的动词:provide(提供),provision(供应, 供给) 这一类一般有如下两个小分类:
A:一般以-t, -s, -se, -l, -n结尾的动词,构成名词时可以加-s(t)ure, 一般具有抽象意义,如: Depart(离去)v.-departure(离开)n. Fail(失败)v.-failure(失败)n. Press(压)v.-pressure(压力)n. B:一般以-te, -de, -se. –ze,–ct.等结尾的动词,构成名词时可以加-ion,如: Invite(邀请)v.-invitation(请帖)n. Protect(保护)v.-protection(保护)n. Extend(伸展)v.-extension(伸张)n. 3.表示动作执行者(施事):
这个形式较为单一,一般只有加后缀-er(-eer, -ier) 或-or(-our),-ant,如: lead(领导)v.-leader(领导人)n. murder(谋杀)v.-murderer(谋杀者)n. engine (引擎)v.-engineer(技师)n. 或:
counsel(劝告)v.-counsel(l)or(顾问)n. govern(统治)v.-governor(统治者)n. 或:
assist(帮助)v.-assistant(助手)n. serve(服务)v.-servant(仆人)n.
4.表示动作被执行者(受事):这一类型较为常见的是后缀:-ee, 如: employ(雇用)v. -employee(雇员)n. examine(检查)v. -examinee(考生)n. 5.表示动作的抽象意义:
一般只有具有抽象意义的动词,才能使用这种方法,构成名词,如:
fulfill(履行)v.-fulfil(l)ment(实现)n. judge(判断)v.-judg(e)ment(审判)n. move(移动)v.-movement(运动)n. treat(对待)v.-treatment(待遇)n.
英语动词变形容词有什么规律
第一,后面加able,afford-affordable;以e结尾的动词则去e加able,love-lovable:表示具有此性质、特点或属性。
第二,后面加ed,scatter-scattered;以e结尾的动词则直接加d,use-used:表示被动性的属性或特点。
第三,不规则的动词则必须记忆,记住其过去分词形式规律不大,意义同上。
第四,后面加ing,run-running,die-dying,变为现在分词形式,有的去e加ing,有的双写加ing,有的改为y加ing,规律同现在分词,表示有正在主动的进行的属性或特点。 动词变形容词类:
1. 在动词后加后缀-ful, 如:
care→careful; use→useful; thank→thankful; help→helpful; wonder→wonderful forget→forgetful
2.后加ED/ING等。如:INTEREST - --INTERESTED WOUND - --WOUNDED 在原动词后加
