女同步语法一:派生法(前缀/后缀的构成规律)
☆同步语法二:合成法(各类合成词的构成与意义)
语法精讲精练
(一)基本定义
派生法(Derivation)是英语构词法中最为活跃的方式之一,通过在一个词根(root)的前面
或后面添加词缀(afx)形成新词。其中:前缀(prefix)加在词根前,改变词义,一般不改
变词性;后缀(sux)加在词根后,改变词性,有时也改变词义。掌握派生规律能大幅提升
词汇量,也是高考语法填空、完形填空、阅读理解中推断词义的重要依据。
(二)核心用法与规律
1.常见前缀(改变词义)
前缀
含义
例词(高中常见)
un-
不、非
unhappy,unable,uncommon
dis-
不、否定、相反
disagree,disappear,disadvantage
in-/im-/il-/
不、非(根据首字母变
体)
incorrect,impossible,illegal,irregular
ir-
re-
再、重新
rebuild,review,recycle
pre-
在.…之前
preview,predict,prevent
mis-
错误地
misunderstand,mislead,mistake
over-
过度、超过
overwork,overeating,overcrowded
underestimate,underdeveloped,
under-
低于、不足
underground
en-/em-
使(动词化)
enable,encourage,embody
高考常考否定前缀的词义转换,尤其是im-il-ir-的拼写规则(如possible→impossible;
legal--→illegal;regular--→irregular)o
2.常见后缀(改变词性)
①名词后缀
后缀
含义
例词

-tion /

④副词后缀

例词

y
地
quickly,carefully,fortunately
quick,careful,fortunate
-ward(s)
朝……方向
forward,backward,upward
for(e),back,up
在…方
-wise
otherwise,clockwise,likewise
other,clock,like
面、方向
高考完形填空常以派生词形式出现(如un-+known→unknown;care+-less→
careless);语法填空则常要求根据语境转换词性(如动词变名词:achieve→
achievement;形容词变副词:beautiful→beautifully)。
(三)核心含义与易混点
1.否定前缀的微妙差异
un-通常用于形容词或过去分词(如unfair,unfinished)
dis常用于动词或抽象名词(如disapprove,disagreement)
Qin-/im-/il-/ir用于以特定字母开头的形容词(如inadequate,immature,
illogical,irresponsible)
注意:有些词有两种否定形式,含义不同,如unhealthy(不健康)vs.unhealthful(不利于
健康的)一一高考偶有辨析。
2.形容词后缀-ful和-less的对比
hopeful(充满希望的)hopeless(没有希望的)
careful(小v心的):careless(粗心的)
理解为“有..的"与"无…的”,是高考常考的反义词构成法。
3.名词后缀-tion与-sion的拼写差异
-tion最普逼(如action,education)
9-sion常出现在-d,-de,-se结尾的动词后(如decide→decision,provide→
provision,express-expression)
而-ssion出现在以-mit,-cede等结尾的动词后(如transmit→transmission,succeed
-→succession)
4.动词→名词的后缀选择
不同动词需搭配不同后缀,记忆需结合词根规律:
以-ate结尾的动词→加-ion→create→creation
O以-ify结尾的动词→加-ication→classify→classification
⊙以-ive结尾的形容词→加-ity→active→activity
(四)高考高频考点总结(附例句)
1.根据上下文推断派生词含义
⑧例句:The unforeseen problem caused a lot of trouble,(un-+foresee+-en
→未预见的;高考中可通过已知部分推测词义)
2.语法填空:词性转换
Q例句:The
(discover)of penicillin is of great significance.答案:
discovery(discover+-y,动词变名词)
3.语法填空:否定前缀的使用
Q例句:tis
(possible)for him to finish the work in two hours.答案:
impossible(以p开头,用im-)
4短文改错:派生词拼写错误
O例句:The situation is getting badly in the area.→worse但若考查派生词,如:
He is a famously writer.→famous(去掉-ly)
5.阅读理解:利用派生法猜词
②例句:The lifeless desert seemed to stretch to the horizon.(Iife+-ess→无
生命的)
