2. The Olympic spirit has taught me that winning isn't everything.
3. It has helped me understand that it's okay to fail.

【分析】
解题时需结合题目给出的中文语义和指定的英语短语结构，同时遵循英语语法规则：1. 第一题使用teach sb to do sth结构，主语it为第三人称单数，谓语动词需用相应形式；2. 第二题要用到提示短语the Olympic spirit，结合语境用现在完成时体现动作的影响，后接that引导的宾语从句；3. 第三题使用it's okay to do sth结构，结合语境用现在完成时表达已产生的影响，后接that引导的宾语从句。
【解析】
1. 根据中文“它教会我们要努力奋斗，公平行事”和提示短语teach sb to do sth，主语it是第三人称单数，一般现在时谓语用teaches，“努力奋斗”对应work hard，“公平行事”对应play fairly，用and连接两个并列成分，故句子为It teaches us to work hard and play fairly.
2. 根据中文“奥林匹克精神教会我，胜利并非一切”和提示短语the Olympic spirit，强调动作对现在的影响用现在完成时has taught，“胜利”用动名词winning作从句主语，“一切”对应everything，故句子为The Olympic spirit has taught me that winning isn't everything.
3. 根据中文“它让我明白，失败也没关系”和提示短语it's okay to do sth，强调对现在的影响用现在完成时has helped，“失败”对应动词原形fail，故句子为It has helped me understand that it's okay to fail.
【答案】
1. It teaches us to work hard and play fairly.
2. The Olympic spirit has taught me that winning isn't everything.
3. It has helped me understand that it's okay to fail.
