巴黎气候变化大会周六晚通过全球气候变化新协定。协定将为2020年后全球应对气候变化行动作出安排。请看本报昨日的报道：

    The global climate summit in Paris forged a landmark agreement Saturday, setting the course for a historic transformation of the world’s fossil fuel-driven economy within decades in a bid to arrest global warming.

    After four years of fraught U.N. talks often pitting the interests of rich nations against poor, imperiled island states against rising economic powerhouses, French Foreign Minister Laurent Fabius declared the pact adopted, to the standing applause and whistles of delegates from almost 200 nations.

    报道中的pit ... against就是“使...敌对”。例如：

    It won’t do you the slightest bit of good if you pit yourself against that giant company with its legion of lawyers.

    有许多律师替这个大公司打官司，跟它作对对你没什么好处。
