this is the house + i lived in the house last year 怎么把这两句话用定语从句合在一起

你说的都对。

this is the house where i lived last year

=this is the house in which i lived last year

where = in which 意为： in the house

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

一般定语从句中，that 如果在从句中做宾语，那是可以省略的，如果在从句中做主语不可省

本句live 是不及物动词，that 又做的是从句的宾语，所以想要让不及物动词接宾语，必须搭配相应的介词in 。但是定语从句中一般如果在关系代词前面加介词，就不用that,要用which.所以最后一句错了，this is the house in which I lived two years ago.=this is the house where i lived two years ago.

The house where I lived ten years ago has been pulled down.把这个句子改成两个简单句

The house has been pulled down.

I lived in the house ten years ago.

将句子的结构梳理清楚，主语有house 和I，分别把这两个主语提出来，然后在把原句抄下来就行了。

Where. 分析：由where引导的地点状语从句，用来强调house
