Salary是可数的.如果你说只是自己的SALARY,那么只有一份工资,是单数.如果你说多人的工资（不是钱数）,就是复数. 譬如：I work in a company with a salary of $4000. The company pays the workers $4000 salaries.
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）是可数名词：She draws a substantial salary. 她的薪水相当高。
