既可作可数名词又可作不可数名词的使用
我在牛津高阶英汉双解词典中看到单词ability既可作可数名词又可作不可数名词,并没有详细说明如何区分该词可数与不可数?以下是词典中的例句看的有点云里雾里.还请高手答疑解惑!
Almost everyone has some musical ability.

He was a man of extraordinary abilities.

students of mixed abilities

A woman of her ability will easily find a job.

I try to do my job to the best of my ability(= as well as I can) .
希望有专业的回答!

作可数名词的是确指一种或几种某些方面的能力 如extraordinary abilities 等
作不可数名词,泛指能力,人是否有能这样做的能力,如my abilityI take care of them to the best of my abilities��They tackled them to the best of their ability.�����������ability�ǿ������������֮ǰ˵�ģ���������ʵ���ȷָһ�ֻ���ijЩ��������� ����仰�Dz��Dz��䰡����ô����������������ʵ���ȷָһ�֣��������ijЩ���������������I try to do my job to the best of my ability(= as well as I can)�˴���ָ�����ļ���I take care of them to the best of my abilities���˴�ָ�ø��ַ����չ˺����ǣ�����˵�ø��ְ취��С��
