Dear Raymott & Soup,
Thank you for your kindest help you have done.
Wern & Martin give many exercises, but no complex sentence in which noun clause does the work of the subject.
I’d like to show one complex sentence:
Exercise 37 (No.9)
They always talk who never think.
The answer: They always talk (Main Clause) , who never think (Adjective Clause)
Here I have a problem. I have already known “Who never think” is a noun Clause, but they answer Adjective Clause.
Could you help me with this problem?
Thank you in advance.
