Salary,wage和pay这三个词都可以表示“工资”,但其含义不同.salary是指非体力劳动者所得到的“工资、薪水”,通常按月,有时按季或年计算(Salary is usually paid monthly,sometimes three months or a year,for a job,esp.as for workers of higher skill and rank);wage指简单劳动或体力劳动者所得的“工资、工钱”,通常按周、日等短期计算发给(Wages are paid weekly for a job,esp.as for labourers or workers.),常用复数形式;pay指不论工作性质如何,针对劳动所支付的报酬,它包含salary和wage(s)(pay is paid for a job),为不可数名词.
所以没有上下文吗?
选A应该它没复数B有
