把 “as...as + 名词” 结构中的as...as 看作一个固定的词组，理解为：作定语修饰后面的名词，表示程度即可，意为“多达；远至；多长；多高”。不要拆开分析，没有实际意义。举例说明：

表示“数量概念”：as much as + 具体钱数/时间等。spend as much as a million dollars

表示“距离”：as far as + 具体地点。walk as far as the station

表示“长度”：as long as + 具体尺寸。The line is as long as ten meters.

表示“高度”：as high as + 具体尺寸。The tree is as high as five meters.

以此类推，举一反三。
