状语 地点状语从句表示地点、 方位， 这类从句通常由where引导。
例如时间状语： Where there is a will, there is a way。 有志者， 事竟成。// They will go where they are happy。 他们想到他们觉得快乐的地方去。
(1)地点状语从句由where，wherever，引导，如：
We must camp where we can get water。
我们必须在能找到水的地方露营。
（2）地点状语从句与定语从句的区别
where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。如：
Go back where you came from。
(where引导地点状语从句）
你从何处来到何处去。
Go back to the village where you came from。(where引导定语从句，修饰village)
回到你来的那个村子里去。
（3）地点状语从句的省略，如
Fill in the blanks with articles necessary。
(necessary前省略了where it is)
在需要的地方填上冠词。
