英语定语从句问题
This is the factory＿＿＿his father works.和This is the factory＿＿＿his factory built.第一个用where,后一个用that或which.为什么,解释一下(详细)

Answer 1

做定语从句的思路就是,把先行词放入后面的定语从句中看是否完整,1.如完整则只需考虑人或事物；2.若不完整则考虑加介词或's;介词+which有时可转换为when、where,for which=why,介词+whom不能转化；'s的用whose.
上面第一句先行词为the factory,放入定语从句中要加介词 his father works in the factory才完整；in the factory=in which=where; 第二句先行词为the factory,放入定语从句中不需要加介词,his father built the factory,the factory指物用which或that,从句中作宾语,故也可省去.你第二句原句空后面的那个factory打错了吧,要改成father吧!
