如何看是否及物动词 还有 先行词~定语从句中That，which,where 等的用法

Question

给点举例子啊

Answer 1

The factory in which/where his father worked has closed.
The factory which was built in 1978 has closed.
第一个例子，the factory 是先行词，从句中的work为不及物动词，the factory做从句的状语，所以可以用关系副词where 表地点，也可以用in which (因为work in the factory)
第二个例子，the factory 是先行词，从句缺主语，the factory 做从句的主语，用关系代词（which/that)
所以分清先行词在从句中所做的句子成份很重要（做主语、宾语用关系代词；做状语用关系副词）
关系代词：that/which/who/whom/whose
关系副词：when, why, where
介词+which
灵活运用就OK了。

Answer 2

及物动词，看字面意思，及物，触及得到物体的，就是说一个动词做出来，后面有没有一个承受者，比如打，后面肯定有一个而被打的东西。这就是及物。不及物就是没有承受者的动词，比如跳，后面就没有什么能被跳。
定语从句中的引导词that which who whom where when等。
先行词是物体时用that或which
先行词时人时用that和who（可是主语或宾语）whom 引导时先行词只能是从句的宾语。
先行词若是地点和时间而且在从句里充当状语就用where，，when
