One day Mary's mother told her best friend of all her hopes and fears. homework 和 hope 及 fear 都是抽象名词,为什么前者不能用复数形式,而后者却可以用复数形式?
按照名词的单复数形式,抽象名词可分四种情形[参见 advice, hope/hopes, science]:
advice(建议), information(信息), news(新闻), happiness(幸福), anger(愤怒), progress(进步), harm(伤害), damage(损坏), envy(嫉妒), work(工作), honour(荣誉), courage(勇气), health(健康), wealth(财富), assistance(援助), bravery(勇敢), knowledge(知识), honesty(诚实), importance(重要性), ugliness(丑陋), good(善良), behaviour(行为)
B. 既可用作不可数名词, 又可用作可数名词的抽象名词, 在这两种用法中, 词义不发生本质变化: hope/hopes(希望), fear/fears(恐惧), belief/beliefs(信念), condition/conditions(条件), science/sciences(科学), success/successes(成功), study/studies(学习)
C. 只能用作可数名词的抽象名词： idea(想法)，remark(意见,评论,话)，situation(局势)，answer(回答)，case(情况)，event(事件)，mistake(错误)，statement(声明)
D. 只以复数形式出现的抽象名词(其单数往往另有含义): goods(商品), manners(礼貌), riches(财富), wishes(祝愿), congratulations(祝贺), letters(文学), spirits(情绪), thanks(感谢)
