地点状语从句 (adverbial clause of place)
   地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型，
   由连词where和复合关系词wherever (=no matter where )引导. 例如：
句型1：Where+地点从句，（there）+主句 
   注意：此句型通常译成“哪里……哪里就……”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，一般都不用there。例如：
   Where there is no rain, farming is difficult or impossible.
   They were good persons. Where they went, there they were warmly welcomed.
   You should have put the book where you found it.
句型2：Anywhere/ wherever+地点从句，+主句 
   注意：anywhere本身是个副词，但是，常可以引导从句，相当于连词，意思相似于wherever, anywhere引导的从句可位于主句之前，也可以位于主句之后。 而wherever本身就是个连词，表示“在何处，无论何处”。例如：
   Wherever the sea is, you will find seamen.
