The doctor did a lot to reduce the patient's fear

问题描述:

The doctor did a lot to reduce the patient's fear
that he would die of the disease.
中的that 为何不能用of which?

The doctor did a lot to reduce the patient's fear that he would die of the diesease.
你可能理解错了.这里"he would die of the disease"是that的同位语,在这里只可以用that连接.不过同位语不一定永远用that 连接,但这里不可以用of which.因为这里不是定于从句结构.
