高考辅导资料AS引导非限制性定语从句
AS引导非限制性定语从句时,通常指的不是主句中的某一个名词(先行词),而是指整个主句表达的内容,对主句所作的陈述进行附加说明,意为―这,如或正如‖。这种从句可位于主句之前,之中或之后。
As we all know, Taiwan belongs to Taiwan, as we all know, belongs to Taiwan belongs to China, as we all 注意下面的习惯用法:
as is well discussed 正如已讨论过的
as is often said 正如通常所说 as is often the case 通常就是这样 as has been pointed 正如所指出的那样 as has been said before 如上所述 as often happens 如同经常所发生的那样 as might be expected正如所料 as is well known to all众所周知
在多数情况下,从句中的谓语助动词可以省略 as explained before 如前面所解释的 as mentioned above 如前面所提到的 as shown in the figure 如图所示 as seen from the table 从表中可以看出 as already discussed
