2.that和why不能引导非限制性定语从句3.as和which引导非限制性定语从句的异同①、The meeting was put off，which/as was exactly what we wanted.as和which都可以引导非限制性定语从句，用来代替整个主句或主句中的一部分内容，有时两者可以互换。
②、The sun rises in the east，as everyone knows.= As everyone knows，the sun rises in the east.He was thrown into prison，which got round throug out the village。
as引导的从句可以放在主句之前，而which引导的从句只能放在主句之后。
定语从句在句首时只能用as, as 具有正如之意，与之搭配的动词一般是固定的。
●As常用在以下习惯用语中●as anybody can see 正如人人都能看到的那样●as is known to all 众所周知●as we had expected 正如我们所预料的那样●as often happens 正如经常发生的那样●as has been said before 如上所述●as is mentioned above 正如上面提到的比较：My brother who is 18 years old is a college student. 我18岁的那个弟弟是大学生。
My brother, who is 18 years old, is a college student. 我弟弟是大学生,今年18岁。
第一句中，限制性定语从句限制了先行词的意义，明确是18岁的那个弟弟（而不是其他的，即有可能还有几个弟弟）。
第二句使用了非限制性定语从句，表明可能只有一个弟弟，18岁，起补充说明作用。
另外，如果先行词是专有名词或独一无二的人或物，通常用非限制性定语从句。
His mother, who loved him very much, died in 1818. 最爱他的母亲于1818年去世了。
I like to chat with Jack, who is a clever boy. 我喜欢和杰克聊天，他是个聪明人。
