一、关于时间定语从句和时间状语从句的区别
关键是看前面有没有先行词,有就是定语从句,没有就是时间状语从句.举例如下：
1.By the time when you arrived in Beijing,we had stayed there for two weeks.
有先行词 the time 那么when you arrived in London就是定语从句
2.when you arrived inBeijing,we had stayed there for two weeks.
没有先行词 when you arrived in London就是时间状语从句
二、关于地点定语从句和地点状语从句的区别
where引导的状语从句是充当主句的地点状语而已,where前面没有先行词.where引导的定语从句它是修饰先行词(表地点的名词/名词短语)的.举例如下：
1.You'd better make a mark where you have any questions.
2.You`d better make a mark at the place where you have any questions.
以上两句字意思相同,但第一个是状语从句,后一个是定语从句.定语从句有先行词THE PLACE,而状语从句没有.状语从句中where引导的句子做地点状语,不出现place.定语从句出现先行词place,再用where引导的定语来修饰place.
