as of 的使用方法

The ocean threw its water over the island with a roar as of many voices.

as of 的意思是？as什么词性，什么用途？

1.The ocean threw its water over the island with a roar as of many voices.

2. The ocean threw its water over the island with a roar of many voices.

大家把句1 和句2 做个对比。

as 和of 之间没任何关系。上面两句的of 介词短语都是定语，修饰a roar，这里的 of表示“充满”之意，a roar of many voices 的意思是：“很多种声音汇集在一块的一声怒吼”。

句1 含有as，表示“像；如”之意，说明这声怒吼好像充满了很多种声音似的，带有比喻含义。

句2 没as，就没“像；如”的意思。
