as引导定语从句的用法
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。
