(5) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。如：My son failed again in the exam, which made me very angry.注意：(1) 关系代词that和关系副词why不能引导非限制性定语从句。(2) as或which引导的非限制性定语从句，可以修饰整个主句或主句的一部分。as引导的定语从句还可以放在主句之前，而which引导的非限制性定语从句要放在句末。如： As has been announced, we should have our final exams next month. We shall have our final exams next month, as / which has been announced.(3) as可引导定语从句时，意为“正如”，which引导时，常意为“这就是。如：As we know, smoking is harmful to ones health. He has a son who likes to play football.试比较以下两个句子在意义上的不同：The college students who knew the truth left the small town.The college students, who knew the truth, left the small town.前一句中有一个限制性定语从句，它对名词的范围作了一定的限制。这个句子的意思是“只有那些知道事实真相的大学生离开了小镇”，并暗示那些不知道事实真相的大学生仍然还留在小镇上。后一句中有一个非限制性定语从句，它对前面的名词没有起到任何限制作用，这句话暗含的意思是：“大学生们都知道了事实真相并离开了小镇。”再比较下面两个句子：He has a son who works in a hospital. (限定性)他有一个在医院工作的儿子。（可能还有别的儿子，不在医院工作）He has a son, who works in a hospital. (非限定性)他有一个儿子，在医院工作。Step 3.
