where在英语中可以引导多种从句，是一个具有多重功能的引导词。它既是高考考查的重点，也是同学们容易混淆的难点。在高二课本前几个单元中也多次出现where引导的从句，仅在第五单元中就出现了where引导的两种从句：

　　1. Some of the native population moved to the inland, mountainous parts of the islands, to Ireland, Scotland and Wales, where they continued speaking their own languages. (定语从句)

　　2. It is built where two rivers come together. (地点状语从句)

　　现将where引导的从句进行归纳，以使大家准确、全面地掌握其用法：

　　一、 引导名词性从句。where引导主语从句、宾语从句、表语从句和同位语从句时, 既可以表示“地点”概念，还可以表示“场合”、“形势”、“情况”等概念。如：

　　Where the meeting will be held is not known yet. (主语从句)

　　I don't know where I am mistaken. (宾语从句)

　　The question is where we can get so much money. (表语从句)

　　The question where he has gone puzzles us. (同位语从句)

　　二、引导定语从句。where引导定语从句时，既可以引导限制性定语从句，也可引导非限制性定语从句；where本身在从句中作地点状语，从句的前面不仅可以用表“地点”的名词作先行词，还可以用有地点含义的抽象名词作先行词。如：

　　I work in a business where almost everyone is waiting for a great chance.

　　There are cases where the word“mighty” is used as an adverb. 在一些情况下，mighty一词可用作副词。

　　三、引导地点状语从句。where引导地点状语从句时，一般修饰句中的动词或动词短语，说明动作发生的地点。where本身在从句中作地点状语, 表达的意思相当于at the place where。如：

　　After the war, a new school building was put up where there had once been a theatre.

　　You should make it a rule to leave things where you can find them again.
