这句话里面为什么有in?in在这里表达的是什么意思?
答
the old castles in which the kings and queens of France used to live.是定语从句,而LIVE是不及物动词,住在某地是live in +地点,IN WHICH = WHERE能不能更详细一点..我不是听的很明白..住在某地是live in+地点的话可不可以是where you can visit the old castles which the kings and queens of France used to live in?in which=where是固定的吗?不论在什么情况下都成立的?castles是先行词，是国王与王后曾经住过的地方，故引导词用WHERE ‘副词’，但如果用WHICH‘代词’时就要加IN ，因为LIVE 是不及物动词，就象刚开始说的住在某地是live in +地点。没错，在定语从句中，in which=where是固定的希望这次你能明白。
