As的用法：
1.按传统用法,用as…as 表比较和用 so…as 表比较二者有别.so…as 结构传统上用于否定句,（ 如莎士比亚“不如井深” ）,和疑问句中（如在如她所说的那样糟糕吗?）,和某些if 从句中（如在 如果象你所说的那样糟,你就该离开 ）.但so…as 结构在美国英语中日趋少见,而在所有语境中使用as…as 现在则是完全可以接受的.在有as…as 和 than 同时用作比较时,在书面语中,第二个as 应该保留.一种写法He is as smart as,or smarter than,his brother,（他如他兄弟一般聪明,甚至超过他了） ,而不应写成 He is as smart or smarter than his brother,这在正式文件中被认为是不可接受的.在很多方言中,用as 代替 that 如 We are not sure as we want to go 或 It's not certain as he left .这种结构在书面语中尚不成立.当as 表示一个因果关系时,前面应有逗号,如She won't be coming,as we didn't invite her.（她不会来这里,因为我们没有邀请她） .当用于表示时间关系时,as 前没有逗号：
She was finishing the painting as I walked into the room.[x]
She was finishing the painting as I walked into the room（我走进房间的时候她刚好画完画）.
2.当as 引导一个从句且位于句首时,应注意弄清 as 是表示“原因”还是表示“与…同时”.句子As they were leaving,I walked to the door 既可表示我向门口走去,因为他们离开了,也可表示在他们离开的时候,我向门口走去.as 有时赘用,引导动词的补助成分诸如 consider,deem,和 account,.如在他们将此认为是民权运动的里程碑.认为此测量标准不必要.这种用法也许源于词的类比用法regard 和 esteem ,在此as 这种形式的用法是标准的：
We regarded her as the best writer among us.[x]
我们认为她是我们中最好的作家.
