as引导定语从句的用法

Answer 1

as引导定语从句的用法This experiment is very simple,as indeed it is.实验非常简单,事实上也确实如此。

as引导定语从句时，有如下结构：“the same…as”，“such…as”，“as…as”“so many (much, few, little)…as”，译作“像……一样的人(或物)”。例如：This is such an easy novel as you can read.

这本小说很容易，你能读得懂。They have never read so many books as I read last year.他们从来都没有读过像我去年读过的那些书。as单独引导定语从句时，修饰整个主句或主句中的一部分，可以放在句首、句中或句末。

当as在从句中作主语时，从句的谓语通常是被动语态或系表结构;as在从句中作宾语时，从句的谓语常用“情态动词+动词原形”构成。常见的结构如下：as is known to all 众所周知as has been said above 如上所述as was expected 正如预料的'那样

as has been pointed out 正如他指出的那样as we all can see (know, hear)正如大家看到的(知道的、听到的)那样。例如：As is known to everybody, the moon travels round the earth once every month.众所周知，月球每个月绕地球转一周。
