参加AEIS入学考试，学好as引导的非限制性定语从句

　　在AEIS入学考试中非限制性定语从句也分成不同的种类，在不同情况下，该从句的使用方法也是不一样的。今天AEIS考试研究中心重点介绍as引导的非限制性定语从句：

　　as引出非限定性定语从句时，代替整个主句，对其进行说明。

　　但通常用于像as we allaknow, as it is know, as is know to all, as it is, as is said above, as always mentioned above, as is usual, as is often the case, as is reported in the newspaper等句式中。

　　as在非限定性定语从句中作主语、表语或宾语，且引出的从句位置比较灵活，可位于句首或句末，也可置于主句中间。通常均由逗号将其与主句隔开。as有“正如……， 就像……”之意。

　　如：

　　As it known to the United States, Mark Twain is a great American writer.

　　美国人都知道，马克?吐温是一位伟大的美国作家。(as在从句中作主语)

　　He forgot to bring his pen with him, as was often the case.
