常用的就是“作为”和一些固定搭配“regard as之类的”


我在网上帮你搜了一篇,as介绍



as 作介词,意为“如同,作为”。例如:
  Unite as one man. (团结得像一个人。)
  as 还可以用于 regard , view , treat , acknowledge 及类似意义的动词之后,构成固定搭配。例如:
  Most of us regard him as a kind man. (我们大多数人认为他是个好心人。)
  We treat them as our friends. (我们把他们当作朋友。)
  4. as 用作关系代词,引导非限制性定语从句,并在从句中充当主语、宾语或表语等,有“正如……”或“据……”的意思;它所引导的从句位置较灵活,可以位于句首、句中或句末。例如:
  As we know from his accent, he is from Shanghai. (正如我们从他的口音中所知道的,他来自上海。)(从句位于句首)
  Mary, as we had expected, passed the exam. (正如我们所预料到的,玛丽通过了考试。)(从句位于句中)
  as 还可以引导限制性定语从句。若先行词被 the same , such 修饰,关系代词应用 as .例如:
  This is such an interesting book as everybody likes to read. (这是一本有趣的、每个人都喜欢看的书。)( as 在从句中作宾语)
  This is such a good book as will help you in your study. (这是一本对你学习有帮助的好书。)( as 在从句中作主语)
  He is not such a kind boy as he looks. (他看上去地个善良的男孩,实际上却不是。)( as 在从句中作表语)
  You must show my wife the same respect as you show me. (你必须尊重我的妻子,就像尊重我一样。)( as 在从句中作宾语)
  需要注意 as 引导定语从句时与 so/such……that 引导的结果状语从句的区别。试比较:
  This is such an interesting book as everybody likes to read. ( as 引导定语从句,代替先行词 book ,在从句中作宾语)
  This is such an interesting book the everybody likes to read it . ( that 引导结果状语从句,因为从句中 read 后面有代词 it 作宾语。)
