Nothing can bring him to sell the house..请说明为什么]
Nothing can bring him to sell the house.Yeah,it is the house [ ]he has spent the happiest days of his life.
A.that
B.which
C.for that
D.in which

选择D
it is the house.句子一
he has spent the happiest days of his life .句子二
1,我把需要填空的句子分成两个句子,俩个句子的主谓宾语全都有.
2,判断是否为定语从句.首先,括号前有house是一个名词作为先行；其次括号后还有一个句子,那么连接两个句子的必然需要一个连词,那就得由关系词来充当；再次判定是关系代词还是关系副词,分析：句子二,主语是he,谓语是spent,宾语是the happiest days of his life,主要是days,在主谓宾语都不缺少情况下,如果有其它的短语,那就是状语,也就是说第二个句子缺少一个状语,那关系词就是关系副词,只能在where when why中选,当然也何以转换成介词+which的结构.in the house.句子二实际完整的应该是
he has spent the happiest days of his life in the house.
句子一it is the house
句子二in the house he has spent the happiest days of his life.
下面我们要把两个句子融合在一起,就要把公共去掉,然后还得补个连词,这里house指的是地点,所以可以用where=in which
it is the house (where / in which) he has spent the happiest days of his life.
如果这还是不够详细的话,只能怪我才疏学浅了.
