高中英语名词性从句语法
As a policeman ,i saw ( where ) there was violence ,drugs were always behind it .
Q1:为什么括号里填where,老师好像说过后面的从句有there这个地点状语,连接词就不能用where了（或者从句有时间副词,连接词就不能用when）.请问怎么改正?
Q2：“ drugs were always behind it ”这句话的连接词是哪个?

答案

where引导的为地点状语从句 where引导的地点状语从句如 Where there is a will, there is a way.---有志者事竟成. 最大的特点是地点状语从句部分属于从属地位,可以略去而只留主句there is a road.而定语从句需要有先行词 这句话没有先行词 完整说来 这句话地点状语从句where there was violence,加上主句drugs were always behind it这个主从复合句做saw的宾语.
A1：在where there was violence这个状语从句中,连接词where在从句中不做主语或者宾语而只作状语,剩下的there was violence 是主系表 也叫主动补结构.where 和 there没有相互制约 也就是只能用其一的规则.完全是根据句法需要来进行句子编码（encoding）.
A2：这句话链接词是where 在there was violence之前的那个where,很简单 一个连接词连接两句完整句,there was violence和drugs were always behind it.是两个完整句 主谓宾都不缺少,where作为连接词引导地点状语从句.
