(单选题)

It was the experience he had at school made him succeed.

A.what; what

B.that; that

C.what; that

D.that; had

参考答案：B

参考解析：

考查关系代词that的用法和强调句的基本结构。句意：正是他在学校的经历使他获得了成功。分析题干可知，第一空为关系代词引导的定语从句，先行词为experience，并在从句中充当宾语；what引导名词行从句，不能引导定语从句，因此排除A、C项；将it was和第二空去掉，句子完整，故为强调句，此处旨在强调“the experience that he had at school”。强调句型：It is/was+被强调部分+that/who。故选B。
