【正确答案】 A

【答案解析】原文：According to China Daily, the so-called “996” work schedule, in which employees work from 9 am to 9 pm, six days a week, spread from IT to other industries. Some companies may even demand more overtime. In a 2018 study, more than 80 percent of Chinese employees said they were overworked and under mental and physical stress. This can cause depression, weight gain and sleep deprivation, which lower work productivity.根据新闻定位句可知，新闻主要介绍了“996”工作模式以及它带给人们身体和精神压力。故选A。
