(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。

　　5. “Was it under the tree _________ you were away talking to a friend?” “Sure. But when I got back there, the bike was gone.

　　A. that B. where C. which D. while

　　【陷阱】此题很容易误选A，认为这是强调句型。

　　【分析】其实此题应选D。做好此题的关键是正确理解上下文的语境。在此句中，it 是代词，指代 the bike，句意为：“当你离开去同朋友谈话的时候，你的自行车是在这树下吗?”“当然，但当我回来时，自行车就不见了。”现在反过来分析一下，假若选A，将此句判为强调句，句子即为 Was it under the tree that you were away talking to a friend? 若进一步转换为非强调句，句子则为 Under the tree while you were talking to a friend，句意显然很荒唐。

　　6. It’s more than half a century _________ my grandfather joined the Party and became a servant to the people.

　　A. when B. that C. since D. while

　　【陷阱】容易误选B，认为这是强调句型。

　　【分析】假若选B，将此句分析为强调句，那么若将此句还原为非强调句就应该是My grandfather joined the Party and became a servant to the people more than half a century. 很显然, 句中的 more than half a century 是一段时间，然而它修饰的谓语动词 joined…became 却是两个终止性动词，这显然不合适。其实，此题应选C，属于“It is+一段时间+since 从句”句型，句意为“我爷爷加入党组织成为人民的公仆已有半个多世纪了”。此句的主句谓语也可以用现在完成时态(has been)，但在口语中多用一般现在时代替。

　　7. It was lack of money, not of effort, _________ defeated their plan.

　　A. which B. as C. that D. what

　　【陷阱】容易误选A，受空格前逗号的影响，误认为这是一个非限制性定语从句，从而误选了A。

　　【分析】其实，此题最佳答案为C，整个句子为强调句，被强调成分为 lack of money, not of effort。由于句中插入 not of effort 这一结构，干扰了许多同学对 it was lack of money that defeated their plan 这一强调句的认识和理解。
