The science of medicine,_____progress has been very lately ,is perhaps the most inportant of all
the sciences.
a.to which b.in which c.which d.with which
.in which 是正确选项.
题目been后面打少了个made,完整的句子是：The science of medicine,【in which 】progress has been 【made】 very lately ,is perhaps the most inportant of all sciences.这是个非限制性定语从句,先行词The science of medicine,关系代词in which,in which逻辑上是in the science of medicine.
把原复合句分拆为两个简单句是：The science of medicine is perhaps the most important of all the sciences.Progress has been made in the sciece of medicine very lately.
再问： 如果 in which 换成 whose 或 of which 在非限制性定语从句中做定语这样理解可以吗？
再答： 这里不能用whose 或of which，关系代词不是做定语，而是做状语。不过i可以用where。你看清楚了吗？是不是打少了个made？
