高中英语定语从句题,
Human facial expressions differ from those of animals in the degree to which they can be controlled on purpose
这句话里to 是从句里的，那in是什么作用？degree也不能用in 他在主句中有用么？

to 是给which用的,因为which指代的是degree,to the degree的意思是“达到...的程度”.in是跟着differ来的,differ in的意思是“在...方面有所不同”,所以在这里的意思是“人类与动物面部表情的不同在于他们有意识控制的程度不同.”
不知道说清楚了没,希望能帮上忙
再问： degree是in的宾语吗？
再答：是的，degree是词组differ in 的宾语，可以说成是介词in的宾语，意思是“在程度上有不同”
