请教句中which在从句所做的成份~The proportion of empty space in a rock is known as its porosity.But note that porosity is not the same as permeability,which measures the ease with which water can flow through a material; this depends on th Could you tell me who he is?这里的从句是宾语从句吗?它在句中所做的成份是什么? 宾语从句引导词在从句中做成份吗 关于从句中关系词所做的成份名词性从句和形容词性从句里的关系词作什么成份?应该如何识别? 定语从句和名词性从句中,which各做什么成份?... that在定语从句中做不做成份,如果做都可以做什么成份,请举例说明. They are all questions to which there are no answers这是个定语从语,为什么要用to which引导呢,which为什么就不行呢?而且to which在定语从句中什么成份啊?那么to which在从句里是代词,类似状语的成份啦 总是能见到关系词不在从句中做作任何成份的句子,这是什么句?如下：There is also the objection that the city has always been the core from which cultural advancement has radiated.句子中that好像不在从句中做任何的 总是能见到关系词不在从句中做作任何成份的句子,这是什么句?如下：There is also the objection that the city has always been the core from which cultural advancement has radiated.句子中that好像不在从句中做任何的 定语从句介词加which常在句中做什么成份 如果是定从,那that在从句中做什么成份, 71：some experts are not surprised that 从句.这个that 从句在句中充当什么成份?some experts are not surprised that 从句.这个that 从句在句中充当什么成份? which在定语从句中可以做主语吗? which在主语从句中做成分不 which在主语从句中做定语么 which为什么不能在宾语从句中做主语 怎样区分定语从句中关系词所做的成分啊!例如：This is the city that/which I visited last year.This is the city where Iworked last year.为什么一个用that或which引导,而另一个用where引导啊?怎么判断先行词在句中 下列关系词通常在定语从句中所充当的成分Whose,that,which,where...通常在定语从句中所充当什么成分呢...
