问题 ______ 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。派生词缀根据在单词中的位置分为前缀(Prefix)和后缀(Suffix)两类。前缀的主要功能是改变词干的语义，一般来说前缀不改变词的词性。后缀主要改变词性，也可以改变语义的功能．词缀(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。
