把该部分放入一个例句中分析一下,例如：She spent as much time as she could learning English（她花费她尽可能多的时间来学习英语）.其中第一个as是一个程度副词相当于so,可译成“如此…”,第二个as相当于从属连词引导一个比较状语从句,通常是个省略句,在此是as she could spend time learning English的省略.此结构一般被总结为：as … as sb can\could 或as … as possible,例如该句也可说成She spent as much time as possible learning English.此时我们可把它看成一个简单句,忽略其语法构成.
