据工信部网站7月25日消息，工信部、科技部等七部委联合发布《关于做好新能源汽车动力蓄电池回收利用试点工作的通知》，确定17省市区为试点。请看本报周五的报道：

China will launch a pilot electric vehicle (EV) battery recycling program in 17 cities and regions, the industry ministry said, with the government keen to head off an emerging pollution threat.

The Ministry of Industry and Information Technology said in a notice published on its website late Wednesday that the cities and regions would encourage car producers to establish recycling service outlets and cooperate with battery producers, used car dealers and scrap merchants to build regional recycling systems.

报道中的head off就是“阻止发生”的意思。例如：

I’m calling the editor now to head off this story before they print it.

我现在就给编辑打电话，让他们不要发这条稿件。
