7.great changes have taken place since then in the factory ___a____we are working.a.where b.that c.which d.therein不是前面有么,为什么要用where
答案选a.where
【解析】定语从句的关键在于：找出先行词（即被定语从句所修饰的名词/代词）,将其代入定语从句中,看从句的连接问题.
如果能直接连接,或可以直接充当定语从句的主语/宾语/表语时,一般使用关系代词；
如果不能,且需要额外加上介词,并一起在定语从句中充当状语时,则使用关系副词.
此题将先行词the factory（先行词只能是名词/代词,有时也可以是句子）放入定语从句中,明显为：we are working (at/in) the factory
即必须加上介词at/in,然后一起在从句中充当（地点）状语,所以用关系副词where.

a

谢谢采纳。

这个in 不是属于定语从句里的
而是和the factoryz在一起构成一个地点状语
而后面的定语从句是修饰FACTORY的，所以用WHERE

你好！
选择a
分析：这是因为正是有了in，致使该定语从句的先行词变为了完整的地点状语in the factory，所以要用where引导定语从句。
