英语构词法,形容词变名词,副词,动词之间的转化关系或窍门,

一般的词典附录里有,可以查.不建议专门去背,最好是见到的单词多了,自己随时总结.

这个蛮复杂的啊,建议多搜搜,积累多了就差不多全了.

1.invention 2.blending 3.borrowing 4.abbreviation
5.acronym 6.back formation 7.analogical creation 8.loan
这是我们学的,应该就是这个吧

派生法：在一个单词的前面或后面加上词缀构成新词的方法, 称为派生法.
如：polite--impolite happy-- unhappy work--worker
合成法：
把两个或两个以上的词按照一定的顺序构成新词的方法被称为合成法构词,又叫复合法.用合成法构成的词是合成词(compound).
如：blackboard(黑板),windmill(风车)
转化法：
把一个词从原来的词类转化为另一种词类,从而使该词具有新的意义和作用,成为一种新词.转化构成的新词,不是词形的变化,而是词性的变化.名词,形容词,动词,甚至代词,副词,介词,连词都可以相互转化.
如： He tried very hard to elbow his way to the front. （elbow 名词用作动词）

place 有“放置”之意
dis- 表否定——不放置,即移走,被拿开,多用于被动,用于被替换的事物
re- 表示“又,再” 再次放置,就是用新的替换了旧的,多用于替换后的事物
obtain ob向+ tain 握,持
attain at向+ tain 握,持
从构词法上来看 这两个词是没有不同的
而且...我也分不出来这两个词的不同..所以..sorry..帮不到你了
dismal entity 不知道...
refine 可以理解为反复的让一样东西变好,所以是精制,精炼
parameter para是旁边 meter是一种量度...放在旁边参照的量度,也就是参量了

用hyphen（连字符 “—”）可以连接两个词构成新词.
如 toughly-charactered (性格坚韧）
按照构词法,副词可以修饰分词,这里就用副词toughly修饰分词charactered,例句：He is toughly-charactered,endowed with swift thoughts and possessing a down-to-earth spirit.(他性格坚韧,拥有敏捷的思维和坚持到底的精神.）
再如 man-eater （食人者）
rubbish-maker(垃圾制造者）
这是名词相互修饰的例子,例句如下
She is really a man-eater.(她简直就是个食人族.）
We cannot become rubbish-makers,destroying our homeland.（我们不能成为垃圾制造者,破坏我们的家园.）
上述是自己随机造出的词,例句也是自己造的,字典里应该查不到.

today I want to talk about english.english has 3 develop procedures:Old English,Middle English and Modern english.Compare with the modern one,old english has less loanwords but more derivational affixes.However,85% of old words do not use anymore.during middle english history,about 10 thousand loanwords were brought in by Norseman and had a crutial development in english's history.modern english become standardization,immobilized and normalization because of the broaden of reading materials' number and scale.
english is consist by prefix,root and suffix.roots are mostly derived from latin,and it determine the word's meaning.prefix can change the sense of a word,like dis-,un-,turn a positive word to a negative one.suffix is the key of part of speech.with -tion or -sion,an adj can be a noun ,for instance.To remember a word easily,just remember the root can string a series of words together.with this method,recall th prefix and suffix can recacll the whole series of word.
that is all i want to say,thank you
