that修饰形容词+名词短语时不定冠词的位置
Sometimes that can be used as an adverbial.
For example,
A - I can't afford that expensive a book.
B - I can't afford that an expensive book.
Which sentence is correct?
"that" describes the "expensive".It can't be omitted here.It's an adverbial,not a pronoun.
答
选A 这里的that是一个副词 修饰expensive 意思是 那么贵
相当于so expensive a book
