成人英语三级阅读理解(36)

Across the whole world, thousands of large and small firms—and government agencies—are installing special software that can block access to individual Web sites from employees' computers. And while many companies are only blocking the obvious suspects, such as sites featuring pornography, gambling or hate speech, some firms are taking matters a step further. According to statistics, 30 to 40 percent of Internet surfing between 9 a.m. and 5 p.m. is not work related.

现在全世界成千上万的大小公司和政府机构都装了一种特殊的软件，用来封锁其雇员的计算机访问那些特殊网站。一些公司只封锁那些有明显嫌疑的站点，比如带有色情、赌博或仇视言论特征的；而有一些公司则采取了更进一步的措施。根据统计，在早上9点到下午5点期间，30%到40%的网络浏览是和工作无关的。
