______ modify the meaning of the stem, but usually do not change the part of speech of the original word.
选项
A、Prefixes
B、Suffixes
C、Roots
D、Affixes
答案
A
解析
本题考查词汇基本概念。派生词缀又根据在单词中的位置分为前缀(Prefix)和后缀(Suffix)两类。前缀出现在单词的前边。前缀的主要功能是改变词干的语义,一般来说前缀不改变园的词性,如,当我们在 friendly前边加上un-时,它的语义发生了改变,但是单词的词性不变。后缀加在词干的后边。后缀主要改变词性,也可以改变语义的功能。间缀(Affix)是前缀和后缀的合称。词根(Root)是指词中含词义主要部分的要素,在此基础上,单词可通过加前缀或曲折词尾或通过语音变化衍生而得。
