分析句子结构the rate below which
America's capacity utilization ,for example,his historically high levels earlier this year,and its jobless rate(5.6% in Aug.) has fallen below most estimates of the natural rate of unemployment ------the rate below which inflation has taken off in the past. 主要是破则号后面得，which在这里是什么成分？好像在这里成了代词，做状语？ 谢谢各位！
which是定于从句的引导词。 看看这个简单的例子： This is the bridge under which the accident occured。 在你的问题中：below which = 例句中的under which。 below which inflation has taken off in the past 是the rate 的从句。
America's capacity utilization 主语 has fallen 谓语 below most estimates of the natural rate of unemployment ------the rate below which inflation has taken off in the past。
状语 该句的状语先由一个介词短语 below most estimates of the natural rate of unemployment构成。破折号后面可以理解为介词宾语的同位语，进一步说明the natural rate of unemployment，但是，这里有了现行词the rate，然后又有一个定于从句限制说明这个自然失业率。
（ below which inflation has taken off in the past）。 学习进步。 李健。
