这道题是考查强调句还是定语从句？还是……
It was in the small house ______ was built with stones by his father ______ he spent his childhood.http://yingyu.chazidian.com
A. which, that                           B. that, which
C. which, which                        D. that, where
【陷阱】几个干扰项均有可能误选，主要是分不清为强调句型，或即使分清为强调句型，也分不清强调哪一个成分。
【分析】答案选A，第一空填 which，用以引导定语从句；第二空填that，为强调句的结构词，被强调部分为 in the small house (以及修饰它的定语从句 which was built with stones by his father)。此题难就难在强调句型中套用了定语从句。请再看类似例子：
(1) It was the boy _____ had been in prison _____ stole the money.(from http://yingyu.chazidian.com)
A. who, where                        B. that, how
C. who, that                            D. that, which
此题答案选C，全句为强调句，被强调成分是 the boy (以及修饰它的定语从句who had been in prison)。
(2) It was just in the room _____ he was born _____ he died.
A. where, which                        B. that, that
C. where, that                           D. which, that
此题答案选C，全句为强调句，被强调成分是 in this room，where he was born 为修饰 the room 的定语从句。
