第一，as soon as与as black as，as red as，as white as结构无异。
第二，这个结构本身还可以简化。
例如：Her hair is as black as ebony. 简化为Her hair is black as ebony.
Her lips is as red as blood. 简化为Her lips is red as blood.
Her skin is as white as snow. 简化为Her skin is white as snow.
所以，怎么切的问题便迎刃而解了，第二个as处切，第一个as没有含义。
第三，回到as soon as，怎么实施教学？先降维再升维，完整展示表达升级过程。
I will call you soon.
I will call you soon as I get home.
I will call you as soon as I get home.
第四：需要从as的本质突破，消灭固定搭配。
总评：语言是运动变化的，就英语而言，多从结构入手，难题迎刃而解。
