the rate below which infaltion has taken off in the past.= the rate wihch inflation has taken off in the past below.先行词 关系代词,主语 谓语动词 时间状语 介词（也可提到关系代词前：...below which...)...which在从句中充当什么成分，做宾语吗？是inflation has taken offthe rate?感觉不通啊给你换个角度看，...inflation has taken off below the rate in the past.由此可以看出，which = the rate 在介词 below 后做介词的宾语。
