Question

表示“像...一样，按照”，引导比较或方式状语从句。 要用几个as？

Answer 1

1. 解答: 这道题的核心是as的不同用法。如果as引导方式状语，用一个as即可，比如as a true friend of mine。如果是比较状语，一般应该用两个as，比如as soon as possible

2. 语法: 英语中单词as的词性多，固定用法也多。作为介词，它表示“像：作为”。比如：dressed as a clown 打扮得像个小丑，work as a courier 以导游的身份工作。作为副词，它可以引导比较结构，并且和介词词性的as连用。比如as much as possible 尽可能的多，as tall as his father 像他父亲那样高大。as也有连词词性，词义和用法类似when，比如：He came up to me as I was speaking. 我说话的时候，他迎着我走上来。

3. 例句：

① He is as tall as you are. 他跟你个子一般高。（副词）

② Our new English teacher, Mr. Green always treats us as friends. 我们新来的英语老师格林先生总是拿我们当朋友看待。

③ She's as good an actress as she is a singer. 她当演员和当歌手都同样出色。

④ Woman as she was, she was brave. 尽管是个女性，她却很勇敢。

Answer 2

只需要用一个as即可。
方式状语从句表示动作进行的方式，除了用as外，还可以用the way、how、however来引导，其中however的语气最强，表示“不管怎样”，引导方式状语从句。
希望我能帮助你解疑释惑。

Answer 3

用几个as 要根据句子的具体意思吧。
如
He ran as fast as his classmate.
他跑的和他的同学一样快。

I will do it as you told me.
我会按照你说的来做。

Answer 4

像...一样：as ... as...，比如 as good as him, as swift as wind 等等。

按照：as per, persuant to, according to，比如 as per your email, pursuant to Clause 2.5, according to the contract 等等。

建议查查字典相关的词条，记一下例句，会很有帮助的。

Answer 5

如果是引导从句的只能用一个as.
