请教一句关于as a result of which的从句
原句：We may define chemistry as the science in which we deal with the chemical change in matter as a result of which it is possible to form a new substance.
句子的意思我能明白：我们可以说,化学是论述物质化学变化的科学,通过化学变化可能形成新的物质.
但是具体的句子成分有点弄不清楚,as之后的内容做什么成分,as a result of which做状语?那之后的it is.做什么成分?书上说是which引导的定语从句,先行词是chemical change,那which之前的as a result of 做什么成分,which在它所引导的定语从句中怎么理解,总不能说(chemical change)it is possible.,即使作状语也理解不通啊
请高手帮忙分析一下这个句子的句子结构

Answer 1

We may define chemistry as a science, in the science we deal with the chemical change. As a result of the chemical change, it is possible to form a new substance.这里是两个定语从句,把先行词还原出来就差不多可以明白了.which 替代的是化学变化,it 就成了一个形式主语,指代的也是那个化学变化 不要纠结到底是什么成分,句子理顺弄懂对了就行吧,一般不会问你哪个是状语哪个是补语吧,又不是搞研究的. 我是那样理解的,不知道对不对也不知道你能不能理解了.
