9. such+名词性词组+that...；so+形容词/副词+that... 如此……以致……

(1)“such+a(an)+形容词+名词+that...”，可以改写成“so+形容词+a(an)+名词+that...”，例句①可以改写成：She is so good a teacher that we all love her.
(2)在“such+形容词+名词复数或不可数名词+that...”结构中，形容词如果是many/few或much/little时，用so不用such，即：so+many/few+可数名词复数+that... ，so+much/little+不可数名词+that...。如：
