央行行长周小川周日在博鳌论坛上指出中国的通货膨胀也在下降，因此必须谨慎、警惕是否会出现通货紧缩。请看本报昨日的报道：

    China’s central bank governor Zhou Xiaochuan warned Sunday that the country needs to be vigilant for signs of deflation and said policymakers were closely watching slowing global economic growth and declining commodity prices.

    Zhou’s comments are likely to add to concerns that China is in danger of slipping into deflation and underline increasing nervousness among policymakers as the economy continues to lose momentum despite a raft of stimulus measures.

    报道中的vigilant就是“警惕”，名词vigilance是“警惕性”，这个词源自vigil (守夜、警戒)，vigilante是“义务警员”。例如：

    We kept a vigilant eye out for alligators and venomous snakes.

    我们警惕地睁大眼睛，以防短吻鳄和毒蛇的出现。
