三.派生法
亦称词缀法,是三种构词法中最活跃的一种,
大约有三分之二的英语单词都是用这种方法构成的。因此,掌握一些常用派生词的构词规律对于我们正确拼写单词和在阅读中猜词能力的培养就显得尤为重要。
在英语的派生词中, 词根决定词的根本意义, 前缀改变词义,
后缀引起词性的改变(个别后缀还会改变词义)。如:ax-表示to:alone, aside, ahead, aloud. “in-”在
“m”之前变体为 “im-“, 在 “ l”之前作 “il-”, 在 “r”之前作 “ir-”;“non-” 和
“en-”则常加在名词或形容词之前。但前者所构成的词仍然是名词或形容词, 而后者却构成了动词。
“un-”常用于动词或形容词之前,其派生词仍为动词或形容词。
有时候,你在阅读中会碰到既有前缀又有后缀的派生词, 只要你确认它的词根, 你就可以猜到它的含义。 如:independent,
disorderly, inattention, rebroadcast, non-communism, nonconductor,
undeveloped, intercultural, unrealizable,unrecognizable, etc.
