Word formation excludes（）
A、affixation and compounding
B、conversion and shortening
C、clipping, acronymy and blending
D、repetition and alliteration
【正确答案】：D
【题目解析】：The most productive means of word-formation are affixation, compounding and conversion. The rest of the new words come from shortening including clipping and acronymy together with blending and other means. 较为多产的方式是词缀法、复合法和转类法。剩余的新词来自缩略法，包括截短法和首字拼音法，加上自拼法和其他途径。重复和押头韵是修辞方法。
