4. as 引导的定语从句

1) as 引导的定语从句可置于句首，而which不可。As we all know, he never smokes.

2) as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which。

3) 非限定性定语从句中出现expect, think, suppose 等表示猜测、想象、预料等时。

She succeeded in her doing the research work , as we expected.

4) the same……as; such……as 中的as 是一种固定结构, 和……一样……。

3. why 指原因，其先行词是原因，起原因状语作用。例如：

Nobody knows the reason why he is often late for school. 没人知道他为什么上学总迟到。

2. where指地点，其先行词表示地点，在句中作地点状语。例如：

　This is the place where he works.这是他工作的地点。
