opening 当"机会"解时是可以用作可数名词

相当与Opportunities，但是与Opportunities不同的是opening是 工作的机会多指工作职位的一个空缺提供给就业者的，而Opportunities 是意泛旨对于整个社会所有的人的机会去就业。job openings means job vacancies provided by a certain employer. job opportunity means the chances for the people of the whole society to get jobs, which reflect s a nation's economy in a certain degree.
