多个形容词修饰名词的顺序

Question

Now that you like the computer so much,why not buy it?
Well,I can't afford ____computer.
中间是用that a expensive 还是that expensive a 呢？

Answer 1

a that expensive. that在这里表示那么地，意思与so一样，是一个副词，用来修饰expensive,故它应在expensive前面。而一台如此贵的电脑用so应该是so expensive a computer,故这里是that expensive a computer

Answer 2

such an expensive或so expensive a才对
你给出的两个都不对

Answer 3

that expensive a =so expensive a (computer) 这里that为副词意思是“如此”相当于so

Answer 4

that a expensive
