有这样一道题：
It was in the small house ______ was built with stones by his father ______ he spent his childhood.
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.
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。
