，当先行词是reason 时，关系副词用why 还是that ?
解题思路： 判断reason在从句中所做的成分
解题过程：
在定语从句中，如果reason在句子中充当成分，如主语、宾语或者表语时，用which/that引导。
The reason which/that he gave to us is true.
（which指代的先行词 reason在定语从句中做gave的宾语，因此可以用which / that）
I don’t believe the reason which/that he has given us for his being late.
（先行词reason在定语从句中做given的宾语，因此可以用which / that）
如果先行词reason不在定语从句中做任何成分时，用why来引导。
I know the reason why she was late.
（She was late句子结构完整，reason在从句中不做任何成分）
再如：
The reason why he did not go to school is that he was ill.
This is the reason which/that he gave his boss in the office
最终答案：略
