This is the house that I lived two years ago.This is the hou

題目：

This is the house that I lived two years ago.This is the house I lived two years ago.
這兩個定語從句對嗎?爲什麼?
某些在從句中充當時間,地點或原因狀語的"介詞+關係詞"結構可以同關係副詞when 和where 互換,例如：
This is the house in which I lived two years ago.
=This is the house where I lived two years ago.
That有時可以代替關係副詞 when,where 或者why引導定語從句表示時間．地點或原因（百度百科）
那麼,是否上面一句句子可以改爲：
This is the house that I lived two years ago.
That有時可以代替關係副詞 when,where 或者why引導定語從句表示時間．地點或原因,that也可以省去.那麼,是否還可以演變成：
This is the house I lived two years ago.
如果錯的話,錯在哪兒了?

解答：

一般定語從句中,that 如果在從句中做賓語,那是可以省略的,如果在從句中做主語不可省
本句live 是不及物動詞,that 又做的是從句的賓語,所以想要讓不及物動詞接賓語,必須搭配相應的介詞in .但是定語從句中一般如果在關係代詞前面加介詞,就不用that,要用which.所以最後一句錯了,this is the house in which I lived two years ago.=this is the house where i lived two years ago.
