【解析】

试题分析：考查定语从句和表语从句。先行词为表原因的the reason，且从句中的gave缺宾语，所以第一空用关系代词that或which用作gave的宾语，that 或which可以省略；第二空是由that引导的表语从句，即The reason …is（was） that…句式。

【知识拓展】

reason理由（名词），reasonable合情合理的（形容词）

1. reason（1）the reason for sth. /doing sth.为某事或做某事的理由。the reason for his being late他迟到的理由

（2）reason理由（名词），在句中做主语，后面的表语从句用that引导。The reason was that he had little education.理由是他受教育少。

（3）reason理由（名词），作先行词，在定语从句中作原因状语时用why引导定语从句，比如：The reason why he was late for class was that his mother was ill.他上课迟到的理由是她的妈妈病了。reason理由（名词），作先行词，在定语从句中作主语或宾语时用that/which,比如：The reason that/which she gave me was that she had got up late.他给我的理由是他起床晚了。

2. reasonable合情合理的（形容词），连系动词后面作表语。

What he said sounded reasonable.他说的话是合情合理的。
