中国政府试图拯救剧烈波动的股票市场免于崩盘的努力周二似乎起作用了，周二收市指数大涨。请看本报昨日的报道：

    China’s efforts to stave off a crash in the world’s most volatile stock market showed signs of gaining traction Tuesday, with the country’s main share benchmarks surging amid signs of intensifying government support.

    Chinese equity markets have fallen more than 20 percent from their peak in mid-June, when a yearlong rally fueled by cheap money shuddered to a halt as a crackdown on leveraged stock trading triggered panic selling.

    报道中的volatile就是“易变的，不稳定的，易挥发的，爆炸性的”，名词是volatility。例如：

    There have been riots before and the situation is volatile.

    以前曾发生过暴乱，现在局势不太稳定。
