谁知道定语从句和状语从句分别该怎样用呀

（一）定语从句有先行词+引导词+陈述句，翻译成……的+先行词。例如： This is a boy who always comes earliest.定语从句引导词由先行词和引导词在从句中位置或作用决定。引导词通常有：表示物的有that,which; 表示人的有who ,whom;表示地点的有where;表示时间的有 when;所有格的有 whose 。例如：1) I prefer the village where we visited last year.
2) Let's go to the village that is quiet and near.
3) The biggest apple that we bought is for you.
4) I'm the person whose boy is good at drawing.
（二）状语从句和主句组成复合句。有因果状语从句如because; 时间状语从句如when, since , while,as；让步状语从句如although, though；条件状语从句如if；比较状语从句如than , as 等。

定语从句是从句作定语
状语从句时从句作状语

时间状语从句：表示过去的过去
例句:after they had enter the house,they went into the dining room
她们逃进了屋里，走进了饭厅。
（这件事情发生在5年以前)
定于从句：主语
是物的时候用which 是人的时候用who 宾语用whom
例句:the woman who is standing unter the tree is TOM's mother
站在树下的那个女的是汤姆的妈妈
