Question

This is the house _______ I want to buy.　　A. in which 　　　B. that 　　　C. whose 　　　D. where

请解释

Answer 1

选B，定语从句选代词代指前面的the house。此处的the house不是做地点状语，而是做名词，故所填代词即buy的宾语，选名词性代词that 。“这就是我想买的房子”。
如果所填代词再从句中作状语，例如 this is the house （ ） I was borned. 从句中born是非及物动词，则所填词不可能在从句中充当宾语，只能做状语，故这是个地点状语从句，填where或 in which.“这是我出生的那座房子”

Answer 2

that
定语从句，that 或which引导
这就是我想要买的房子。

Answer 3

B
the house 作先行词，that引导的定语从句，特征是that(house)在定语从句中做成分，充当buy的宾语。
