考点二 非限制性定语从句中需要注意的几个问题
1.关系代词和关系副词的选择。
在非限制性定语从句中,关系代词和关系副词的选择方法与限制性定语从句一样:关系词在从句中作主语或宾语时,用关系代词(which, who, whom, whose, as);在从句中作状语时,用关系副词(when, where)。

这位老人有一个女儿,她是一名艺术家。(who在从句中作主语)
He will put off the picnic until May 1st, when he will be free.
他将把野餐推迟到5月1日,那时他将有空。(when在从句中作时间状语)
2.关系副词why不能引导非限制性定语从句,但可用for which代替why来引导。
He didn’t tell us the reason, for which he went abroad without telling anybody.
他没有告诉我们理由,为什么没有告诉任何人就去了国外。
3.非限制性定语从句由“介词+关系代词”引导时,其中的关系代词用which或whom。
