Accordingly to recent news reports (NYT, WSJ), the Chinese government has mandated that, beginning July 1, every PC sold in China must include a censorship program called Green Dam. This software is designed to monitor internet connections and text typed on the computer. It blocks undesirable or politically sensitive content and optionally reports it to authorities. Green Dam was developed by a company called Jin Hui and is available as a free download. We examined version 3.17.
这段我先翻译一下，其它的，大家自己翻译：
据纽约时报、华尔街日报最近报道，中国政府要求自2009年7月1日起，国内计算机在销售时必须预装绿坝审查软件。该软件用于监控计算机的网络连接和文本输出，可阻止不良或敏感政治内容并有选择性地报告给官方。绿坝软件由金惠开发并提供免费下载，我们对该软件的3.17版本进行了测试。
